Description

  The present invention relates to an electrical connector for a cable having a terminal with a cable (hereinafter referred to as “cable connector”), and further to the electrical connector for a board connected to the cable connector (hereinafter referred to as “substrate connector”). The connector assembly.

  Patent Document 1 discloses a cable connector having a terminal with a cable in which a cable is connected to a connection portion of a terminal made of a metal plate. This cable connector is fitted into a fitting recess formed on the board connector as a mating connector attached to the circuit board and opening upward. In this Patent Document 1, the cable extending direction is described as “front” and the terminal insertion direction is “backward”. However, here, for easy comparison with the present invention, the terminal insertion direction is “front”. The cable extending direction is described as “rearward”. In this Patent Document 1, a terminal housing hole extending in the front-rear direction perpendicular to the connector mating direction and parallel to the surface of the circuit board is formed in the housing of the cable connector, and is crimped to the front end portion of the cable extending rearward. The terminal thus inserted is inserted into the terminal receiving hole from the rear side toward the front and is received in the terminal receiving hole.

The housing is formed with an engagement hole that communicates between the terminal receiving hole and the outside through the upper wall of the housing. A lance projecting obliquely upward and rearward is formed on the upper surface of the terminal. When the terminal is inserted into the terminal receiving hole, the lance is elastically deformed to enable insertion. Then, in a state where the terminal is accommodated in the terminal accommodation hole of the housing, the lance enters the engagement hole of the housing and engages with the inner surface of the engagement hole in the rear direction, thereby the terminal accommodation hole. The terminal is prevented from coming off from the terminal.
JP 2002-33150 A

  When the lance is formed on the terminal as in Patent Document 1, the lance is formed by cutting and raising a part of the terminal. However, in a terminal made of a metal plate, a lance formed in a tongue shape by cutting and raising has low strength. For example, in the case where the lance in Patent Document 1 is formed by cutting and raising a part of the terminal, when the strong rearward force acts on the cable, the inner surface of the engagement hole and the lance are locked. In addition, an excessive force is applied to the lance so that the lance is easily bent and deformed in the thickness direction of the lance, and further, the terminal may be detached from the housing. When the strength of the lance is increased so as to avoid deformation or breakage of the lance, the inner surface of the engagement hole may be damaged by the engagement with the lance. In addition, it is difficult to obtain elastic deformation when the terminal is inserted into the terminal receiving hole, which makes insertion difficult.

  In view of such circumstances, the present invention, in the cable connector, even if an inadvertent force acts on the cable in the extending direction of the cable, without causing deformation or damage to the terminal or the housing, An object of the present invention is to provide an electrical connector for a cable that reliably prevents a terminal from being detached from a housing, and an assembly having the connector and a board connector.

<First invention>
An electrical connector for a cable according to the present invention is an electrical connector for a cable having a terminal with a cable in which a cable is connected to a connection portion of a terminal made of a metal plate and the cable extends rearward, and is attached to a circuit board. The terminal is fitted to the fitting portion of the board electrical connector as the mating connector in a fitting direction perpendicular to the extending direction of the cable, and the terminal has a contact portion in front of the connection portion, and the contact portion Is connectable to the corresponding contact portion of the board electrical connector.

  In such an electrical connector for cable, in the present invention, the terminal has an extending portion that is positioned forward of the connecting portion and extends forward, and a restricted portion that extends from the front end portion of the extending portion in the fitting direction. In the connector fitting state, the regulated portion is positioned in front of the regulating portion provided on the terminal of the board electrical connector, and the rear surface of the regulated portion faces the front surface of the regulating portion. The movement of the restricted portion to the rear is restricted by the restricting portion.

  In such an electrical connector for cables, the regulated portion is formed as a part of a metal terminal and does not have to have elasticity like a lance, so that the strength can be increased and When a large inadvertent force is applied to the rear, the regulated portion can sufficiently withstand even if it comes into contact with the regulating portion formed as a part of the metal terminal of the board electrical connector. Further, since the restricting portion is a metal, it has sufficient strength, and the restricting portion is not damaged when the restricted portion comes into contact with the restricting portion. Furthermore, the regulated portion extends in the fitting direction from the front end portion of the extending portion extending forward, and the rear surface of the regulated portion is opposed to the front surface of the regulated portion. The portion can be formed to have a large size in the width direction (a direction perpendicular to both the front-rear direction and the fitting direction) and the size in the fitting direction. Therefore, when an inadvertent force is applied to the cable in the rearward direction, the rear face of the restricted part and the front face of the restricting part are reliably applied even if there is a slight displacement of the terminal in the width direction and the fitting direction. Touch. As a result, the rearward movement of the restricted portion is reliably restricted by the restricting portion.

<Second invention>
An electrical connector for a cable according to the present invention is an electrical connector for a cable having a terminal with a cable in which a cable is connected to a connection portion of a terminal made of a metal plate and the cable extends rearward, and is attached to a circuit board. The terminal is fitted to the fitting portion of the board electrical connector as the mating connector in a fitting direction perpendicular to the extending direction of the cable, and the terminal has a contact portion in front of the connection portion, and the contact portion Is connectable to the corresponding contact portion of the board electrical connector.

  In such an electrical connector for cable, in the present invention, the terminal includes a pair of extending portions that are positioned forward of the connecting portion and extending forward, and a regulated portion that connects the extending portions. In the connector fitting state, the pair of extending portions are positioned on both sides of the restricting portion provided on the terminal of the board electrical connector in a direction perpendicular to both the front-rear direction and the fitting direction. And the said restricted part is located ahead of the said restricting part, the rear surface of this restricted part is facing the front surface of the restricting part, and the movement of the said restricted part to back is restricted by the said restricting part. It is characterized by being adapted.

  In such an electrical connector for cable, similarly to the first invention, the regulated portion is formed as a part of a metal terminal and does not have to be elastic like a lance, so the strength is increased. When a large inadvertent force acts on the cable backward, the regulated part is sufficient even if it comes into contact with the regulating part formed as a part of the metal terminal of the board electrical connector. Can withstand. Further, since the restricting portion is a metal, it has sufficient strength, and the restricting portion is not damaged when the restricted portion comes into contact with the restricting portion. Furthermore, since the said restricted part has connected the extension part located in the both sides of a restriction part, when it sees in the front-back direction, a restriction part and a restricted part cross | intersect. Therefore, when an inadvertent force is applied to the cable in the rearward direction, the rear surface of the restricted portion and the front surface of the restricting portion can be reliably applied even if the terminal is slightly displaced in the width direction and the fitting direction. Touch. As a result, the rearward movement of the restricted portion is reliably restricted by the restricting portion.

  It is preferable that the extended portion has a front end bent in the fitting direction, and the regulated portion is formed by connecting the front ends of the extended portion. In this way, the strength of the extended portion is improved by bending the front end portion of the extended portion in the fitting direction. Further, since the rear surface of the restricted portion extending in the fitting direction is formed of a plate surface of a metal plate, the rear surface of the restricted portion can be increased by increasing the size of the restricted portion in the width direction and the fitting direction. The area can be increased. This makes it possible to increase the contact area between the rear surface of the restricted portion and the front surface of the restricted portion. As a result, even if the terminals are misaligned in the width direction and the fitting direction, the movement of the restricted portion to the rear is restricted by the restricting portion, and the terminal of the cable electrical connector is reliably prevented from coming off.

  The contact portions are formed as a pair of contact pieces that allow the corresponding contact portion of the terminal of the electrical connector for the board to enter when the connector is fitted, and press and contact the corresponding contact portion, and the pair of contact pieces are: It is preferable that the front end in the fitting direction is curved so as to be wound inside the opposite direction.

  In this way, the pair of contact pieces are curved so that the tips in the fitting direction are wound inwardly in the opposite direction, so that when the connector is fitted, the curved parts become the introduction parts, and the board The terminal of the electrical connector is guided and easily enters between the contact pieces. In addition, since the tip of the contact piece is curved and it is not necessary to provide the introduction portion at a position opposite to the approach direction than the contact portion, the contact piece can be formed with a smaller size in the fitting direction. Therefore, it is possible to reduce the height of the cable connector.

  The contact portion preferably extends in a cantilever shape toward the front. By forming the contact portion in a cantilever shape extending forward, it is possible to increase the length of the contact portion in the front-rear direction even if the size in the fitting direction, that is, the connector height direction is reduced. it can. Therefore, it is possible to form the contact portion with a sufficient length in the front-rear direction while maintaining the cable electrical connector low, and as a result, the elasticity of the contact portion is increased and the terminals of the board electrical connector are connected. The contact pressure can be secured.

<Third invention>
A connector assembly according to the present invention includes the electrical connector for a cable according to the first invention or the second invention, and an electrical connector for a board that is fitted and connected to the electrical connector for the cable. The terminal of the electrical connector for boards is formed so as to be positioned in the range of the terminal with cable in the fitting direction. As described above, the terminals of the electrical connector for board are positioned in the range of the terminal with cable in the fitting direction, so that the height of the connector assembly can be reduced.

<Fourth Invention>
A connector assembly according to the present invention includes the cable electrical connector according to the first invention or the second invention, and a board electrical connector fitted and connected to the cable electrical connector. And an electric connector for a cable having a fixed portion that is locked and fixed to the housing of the board connector, and a connecting portion that is electrically connected to a corresponding circuit portion of the circuit board. The connection part and the contact part of the circuit board, and the fixing part and the connection part of the electrical connector for board are provided at non-overlapping positions in the front-rear direction.

  If the connection part, contact part, fixing part, and connection part are provided at overlapping positions in the front-rear direction, these parts cannot be provided at the overlapping positions in the height direction, so they are shifted in the height direction. Must be provided. As a result, the height dimension of the assembly becomes large. In the present invention, in the connector fitting state, the connection part and the contact part of the cable electrical connector and the fixing part and the connection part of the board electrical connector are provided at non-overlapping positions in the front-rear direction. There is no need to shift each part in the height direction, and the height of the connector assembly can be reduced. In the connector assembly of the present invention, there is a great demand for space saving in the height direction, i.e., low profile, but there is room in the direction in which the cable extends, i.e., in the front-rear direction. There is no problem even if the size in the front-rear direction of the connector assembly is somewhat increased by providing the non-overlapping positions.

<Fifth invention>
A connector assembly according to the present invention includes the electrical connector for a cable according to the first invention or the second invention, and an electrical connector for a board that is fitted and connected to the electrical connector for the cable. The corresponding contact portions of the terminals of the board electrical connector reach between the extended portions of the terminals of the cable electrical connector.

  By making the dimension in the mating direction of the corresponding contact portion of the board electrical connector so that the tip of the corresponding contact section reaches between the extension portions of the cable electrical connector in the connector mated state. The effective fitting length, that is, the distance in the fitting direction from the tip of the corresponding contact portion in a state where the connectors are completely fitted to the proper contact position between the corresponding contact portion and the contact portion of the cable connector is increased. It can be secured. Thereby, in the connector fitting state, the contact position between the contact portion of the cable electrical connector and the corresponding contact portion of the board electrical connector is changed from the normal contact position when the connectors are completely fitted. Even if the contact part is slightly shifted from the front end side of the corresponding contact part, it is possible to ensure electrical continuity between the contact part and the corresponding contact part. Therefore, even if there is a manufacturing error in the above fitting direction or an assembly error in the same direction of each part of the connector, or even if the connector fitting state is incomplete, the contact portion And a stable contact state of the corresponding contact portion can be ensured.

  In addition, even when an inadvertent external force acts on the contact portion between the contact portion and the corresponding contact portion in the connector fitting state, the effective fitting length is ensured to be large, so that the terminals can be easily detached. The stable contact state between the terminals can be favorably maintained.

  In the cable connector according to the present invention, since the rear surface of the restricted portion extending in the fitting direction faces the front surface of the restricting portion, the restricted portion has a large size in the width direction and a size in the fitting direction. It is possible. Therefore, when an inadvertent force is applied to the cable in the connector mating state, even if there is a slight displacement of the terminal in the width direction or mating direction, the front of the regulating part and the regulated part The rear surface comes into contact with certainty. As a result, the movement of the restricted portion to the rear is restricted, so that the terminal of the cable connector is reliably prevented from coming off. Further, the regulated portion is formed on a metal terminal and can have sufficient strength against the force received at the time of contact, and the regulated portion is a metal terminal of the board connector. The terminal of the cable connector will not be deformed or damaged even if it comes into contact with the restricting portion formed on the cable. Further, since the restricting portion is a metal, it has sufficient strength, and the restricting portion is not damaged when the restricted portion comes into contact with the restricting portion.

  Furthermore, when the restricted portion is configured to connect the extending portions located on both sides of the restricted portion in the width direction, the restricted portion and the restricted portion intersect when viewed in the front-rear direction. As a result, even if there is a slight misalignment of the terminal in the width direction or the mating direction, the front surface of the restricting portion and the rear surface of the restricted portion can be reliably brought into contact with each other. Removal is reliably prevented.

  Further, in the connector assembly according to the present invention, since the terminal of the board connector is located in the range of the terminal with the cable in the fitting direction in the connector fitting state, the connector assembly can be reduced in height. . Furthermore, the connection and contact portions of the cable connector and the fixing and connection portions of the board connector are provided at non-overlapping positions in the front-rear direction, so that it is not necessary to shift the portions of both terminals in the fitting direction. Further, the connector assembly can be further reduced in height.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

<First embodiment>

FIG. 2 is a plan view showing the position of the cable connector and the board connector of FIG. 1 shifted in the cable extending direction. 3 is a cross-sectional view taken along the line III-III of FIG. 2 at a plane perpendicular to the circuit board, showing a cross section at the terminal position in the connector width direction. 3A is a cross section before the connector for the cable and the connector for the board are fitted, FIG. 3B is a cross section immediately after the fitting of both the connectors, and FIG. And the cross section after the movement of the moving member of the connector for substrates is shown.

  In this embodiment, the connector 10 includes a cable connector 10 having a terminal with a cable and a board connector 40 which is a mating connector attached to a circuit board (not shown). The connector assembly 1 includes a cable C attached to the cable connector 10 in a direction perpendicular to the circuit board in a state where the cable C is parallel to the surface of the circuit board and extends rearward (leftward in FIG. 1). 1 can be fitted and connected with the fitting direction as the downward direction.

  As shown in FIG. 1, the cable connector 10 includes a substantially rectangular parallelepiped housing 20 and a terminal 30 (see FIGS. 3A to 3C) to which the cable C is attached, that is, a terminal with a cable. have. A plurality of terminal holes 21 penetrating in the front-rear direction are formed in the housing 20 in a line in the connector width direction. The housing 20 protrudes toward the outside of the connector at a position closer to the rear of both side surfaces extending in the front-rear direction, and the first locked portion 20A formed by thinning the front ends of both side edges. It has the 2nd to-be-locked part 20B (refer FIG. 1). As will be described later, the first locked portion 20A and the second locked portion 20B are provided with a first lock portion 71A-1 and a second lock provided on the moving member of the board connector 40, as will be described later. It latches in part 71A-2 and a connector detachment direction, respectively. Hereinafter, for convenience of description, the first locked portion 20A and the second locked portion 20B are collectively referred to as “locked portions”.

  As is often seen in FIG. 3A, the terminal hole 21 penetrates in the front-rear direction, and a lower opening 22 that opens downward is formed at the front. The lower opening 22 has a terminal receiving portion 22A on the front end side and a locking hole 22B on the rear side thereof. The terminal receiving portion 22A is an opening for receiving the contact portion 62 of the terminal 60 of the board connector 40 from below, and the locking hole 22B forms a space for receiving a locking portion 33 of the terminal 30 described later. The inner wall surface of the stop hole 22B is engaged with the engaging portion 33 in the rearward direction to prevent the terminal with cable from coming off. That is, when an inadvertent force is applied to the cable C in the rearward direction, the rear end portion of the locking portion 33 is locked with the edge portion of the locking hole 22B in the front-rear direction. Terminal disconnection is prevented. The board connector 40 will be described later.

  4A and 4B are perspective views of the terminal 30 of the cable connector 10 and the terminal 60 of the board connector 40 according to the present embodiment as viewed from the rear. FIG. 4A is a state before the connector is fitted, and FIG. The state after fitting is shown. FIG. 5 is a perspective view of the terminal 30 of the cable connector 10 according to the present embodiment as viewed from the front. FIG. 6 is a cross-sectional view taken along the line VI-VI in FIG. 4B and shows a cross section at the position of the contact portion of both terminals in the front-rear direction.

  The terminal with cable is obtained by crimping the terminal 30 to the cable C. The terminal 30 has a shape obtained by rounding a metal plate into a substantially cylindrical shape, and as is often seen in FIGS. 3 (A), 4 (A), (B), and FIG. The connection part 32 and the latching | locking part 33 which extended below from 31 and were integrally formed with this base 31 are provided in order toward the front from the rear part. The terminal 30 has a pair of contact portions 34 that are located in front of the locking portion 33 and are connected to the front end portion of the locking portion 33 and extend forward. Further, the terminal 30 has an extending portion 35 that is located in front of the base portion 31 and extends forward, and a regulated portion 36 that connects the front end portions of the extending portion 35 to each other.

  The connection part 32 has a crimping part 32A and a crimping part 32B provided in front of the crimping part 32A. The caulking portion 32A has a pair of leg pieces and is caulked by the covering of the cable C, whereby the terminal 30 is held by the cable C (see FIG. 3A). The crimping part 32B also has a pair of leg pieces, and is crimped or soldered to the core wire C1 of the cable C and electrically connected to the core wire C1 (see FIG. 3A). In FIGS. 4A, 4B and 5, the caulking portion 32A and the crimping portion 32B are attached to the cable C, that is, before the caulking portion 32A and the crimping portion 32B are crimped. Shown open.

  The locking portion 33 has a pair of leg pieces, and the lower ends of both leg pieces are bent inward in the opposing direction, as is often seen in FIGS. 4 (A) and 4 (B). As shown in FIGS. 3A to 3C, the lower end of the locking portion 33 extends downward to a position where it enters the locking hole 22 </ b> B of the housing 20. The contact portion 34 is a pair of arm pieces extending in a cantilever shape toward the front with the plate surfaces facing each other in a direction perpendicular to both the front-rear direction and the fitting direction (vertical direction), that is, in the width direction. The elastic deformation is possible in the width direction. In this embodiment, since the contact portion 34 is formed to extend forward in a cantilever shape, the length of the contact portion 34 can be reduced even if the size in the fitting direction, that is, the connector height direction is reduced. The height can be increased in the front-rear direction. Therefore, it is possible to form the contact portion 34 with a sufficient length in the front-rear direction while maintaining the cable connector 10 at a low profile. As a result, the elasticity of the contact portion 34 is increased and the terminal 60 of the board connector 40 is connected. Contact pressure can be secured.

  As often seen in FIG. 5, the lower end of the front portion of the contact portion 34 is formed as a winding portion 34 </ b> A that is curved so as to be wound inward in the width direction that is the opposing direction of both arm pieces. The winding portion 34A is located within the range of the extending portion 35 in the front-rear direction. Further, the winding portion 34A allows the contact portion 62 of the terminal 60 of the board connector 40 to enter when the connector is fitted, and is elastically pressed and brought into contact with the contact portion 62. Each winding portion 34A is formed with a convex portion protruding inward in the opposing direction, as is often seen in FIGS. 3A and 6, and the convex portion contacts the contact portion 62 of the terminal 60. A large pressure is secured.

  In the present embodiment, the lower end of the contact portion 34 is curved to form the winding portion 34A. Therefore, when the connector is fitted, the curved portion at the lower end serves as an introduction portion and contacts the terminal 60 of the board connector 40. The part 62 is guided to easily enter between the winding parts 34A. In addition, since the lower end of the contact portion 34 is curved and it is not necessary to extend the introduction portion below the winding portion 34A, the contact portion 34 can be formed with a smaller size in the fitting direction. . As a result, the height of the cable connector 10 is reduced.

  As shown in FIGS. 4A, 4B and 5, the front portion of the base 31 is beaded in a T shape having a portion extending in the front-rear direction and a portion extending in the width direction. Thus, the reinforcing portion 31 </ b> A is formed, and a concave portion is formed on the upper surface of the base portion 31 and a convex portion (not shown) is formed on the lower surface of the base portion 31. By providing the reinforcing portion 31A, strength against bending stress in the thickness direction over the front-rear direction is ensured in the portion extending in the front-rear direction. Moreover, in the portion extending in the width direction, strength against bending stress in the plate thickness direction over the width direction is ensured. Further, the portion extending in the width direction has an end portion extending to a connecting portion between the base portion 31 and the locking portion 33, that is, bent downward, and is bent in the thickness direction at the bent portion. Strength against stress is secured.

  The extending portion 35 forms a pair of arm pieces and extends in parallel from the front portion of the base portion 31 toward the front, and the front end portion thereof is bent downward. By bending the front end portion of the extending portion 35 in this way, the strength of the extending portion 35 is improved. In this embodiment, each extending portion 35 is subjected to bead processing so that a concave portion is formed on the convex bent surface at the bent portion and a convex portion is formed on the concave bent surface, as is often seen in FIG. Thus, the reinforcing portion 35A is formed, and the strength against bending stress in the thickness direction is ensured at the bent portion.

  As is often seen in FIG. 5, the regulated portion 36 is in a state where the front end portions of the extending portion 35 are connected to each other and extends in the width direction. The regulated portion 36 is located in front of the winding portion 34A of the contact portion 34, as can be seen in FIG. As is often seen in FIGS. 4A, 4 </ b> B, and 5, the terminal 30 is formed with a base portion 31, a pair of extending portions 35, and a hole portion 37 surrounded by the regulated portion 36. . The hole portion 37 forms a space that allows the tip portion of the contact portion 62 of the terminal 60 to enter when the connector is fitted.

  The extending portion 35 and the regulated portion 36 form a slit-like hole portion 37 extending in the front-rear direction on the metal plate forming the terminal 30 and plate the metal plate at a position closer to the front in the hole portion 37. It is formed by bending downward in the thickness direction. In the present embodiment, when forming the extending portion 35 and the regulated portion 36, as described above, a position closer to the front in the hole 37, that is, a position within the range of the hole 37 in the direction in which the hole 37 extends. Then, the extending portion 35 is bent. In this way, by bending the extending portion 35 at a position within the range of the hole portion 37, not only the tip portion of the contact portion 62 is allowed to enter the hole portion 37 but also the hole portion. Compared with the case where the metal plate is bent at a position outside the range, bending can be easily performed.

  In the case of a metal plate that can be bent easily, the hole does not need to reach the bent portion, and the hole is formed only at a position corresponding to the contact portion of the terminal of the board connector in the front-rear direction. It is good.

  The board connector 40 includes a synthetic resin housing 50 as an electrical insulating material, a plurality of metal terminals 60 arranged and held by the housing 50, and a front-rear direction with respect to the housing 50, that is, a circuit board. And a synthetic resin moving member 70 movably attached in a parallel direction, and a plurality of metal fixing fittings 80 attached to the housing 50.

The U-shaped portion and the bottom wall portion 53 form a receiving recess 54 that receives the cable connector 10 from above.

  The front wall portion 51 is formed with slit-like terminal holding holes 51A penetrating in the front-rear direction at predetermined intervals in the longitudinal direction, and the plate-like terminals 60 are pressed into the terminal holding holes 51A and held from the front. (See FIGS. 3A to 3C). The terminal 60 will be described later.

  As will be described later, a first locking portion (not shown) and a second locking portion 52A that are locked in the front-rear direction and a second locking portion 52A project outwardly in the connector width direction. Protrusively formed. In the present embodiment, the second locking portion 52A is formed behind the first locking portion, and the front surface and the rear surface are tapered surfaces.

  The rear end portion of the side wall portion 52 is formed as a fixing bracket holding portion 52B that protrudes in the connector width direction and the height direction and has a rectangular parallelepiped outer shape that is larger than the other portions. The fixing bracket holding part 52B is formed with a slit-shaped fixing bracket holding groove 52B-1 that opens rearward and extends in the front direction, and the fixing bracket 80 is press-fitted into the fixing bracket holding groove 52B-1 from the rear and held.

The fixed portion 82 is soldered to the circuit board, and the board connector 40 is fixed to the circuit board.

  The terminal 60 is made of a metal plate, and as is often seen in FIGS. 3A to 3C, a base 61 extending in the front-rear direction in contact with the bottom wall portion 53, and a rear side of the base 61 It has a contact portion 62 that protrudes upward from the base portion 61 at a shift position, that is, a left position in FIG. The front portion of the contact portion 62 is formed as a later-described restricting portion 62A. The contact portion 62 extends from the terminal holding hole 51 </ b> A of the housing 50 into the receiving recess 54 as can be seen in FIGS. 1 and 3A. Further, the terminal 60 has a mounted portion 63 that extends upward from the base portion 61 at an intermediate position in the front-rear direction and has a protruding end at the tip. The tip of the attached portion 63 bites into the inner surface of the terminal holding groove 51 </ b> A of the housing 50 and is locked to the housing 50, whereby the terminal 60 is fixed to the housing 50. As is often seen in FIGS. 3A to 3C, the terminal 60 having such a configuration has a dimension in the connector fitting direction, that is, a vertical direction substantially equal to the dimension in the same direction of the terminal 30 of the cable connector 10. The same.

  In the terminal 60, a concave portion between the contact portion 62 and the attached portion 63 in the front-rear direction is formed as a receiving portion 64 that receives the restricted portion 36 of the terminal 30 of the cable connector 10 when the connector is fitted. The terminal 60 extends downward to the same level as a circuit board (not shown) in the connector height direction at a position closer to the front, that is, a right position in FIGS. 3A to 3C, and is parallel to the circuit board. Is bent in a certain direction (perpendicular to the paper surface), and a portion parallel to the circuit board is formed as a connecting portion 65. The terminal 60 is electrically connected to the corresponding circuit portion by soldering the connection portion 65 to the corresponding circuit portion of the circuit board.

  As shown in FIG. 1, the moving member 70 includes two arm portions 71 extending in the front-rear direction at substantially the same interval as the side walls 52 of the housing 50, and the front end of the arm portion 71 extending in the connector width direction. It has the connection part 72 which connects parts. The arm portion 71 has a shape in which an upper plate portion 71A and a lower plate portion 71B having plate surfaces perpendicular to the connector height direction are arranged at intervals in the connector height direction. The portion 71A and the lower plate portion 71B are connected by a locked portion 71C at a position of the rear end portion of the arm portion 71 closer to the connector outward (see FIG. 1).

  As is often seen in FIG. 2, the upper plate portion 71 </ b> A of each arm portion 71 has an edge portion on the inner side of the connector in the connector width direction positioned more inside the connector than the side wall portion 52 of the housing 50. The edge portion of the upper plate portion 71A has a planar shape having a step portion at an intermediate position in the front-rear direction, the front side portion extends inward of the connector from the rear side portion, and the front side portion is the first side portion. One lock portion 71A-1 and the rear side portion are formed as a second lock portion 71A-2.

  As will be described later, the first lock portion 71A-1 and the second lock portion 71A-2 are connected to the cable connector 10 and the connector detachment direction (the upward direction in FIGS. 3A to 3C) at the detachment prevention position. ) To prevent the cable connector 10 from being detached. Hereinafter, for convenience of explanation, the first lock portion 71A-1 and the second lock portion 71A-2 are collectively referred to as a “lock portion”.

  As is often seen in FIG. 1, the locked portion 71C is located on the outer side of the connector with respect to the side wall portion 52 of the housing 50, and the side surface of the locked portion 71C on the inner side of the connector is the side wall portion. 52 substantially coincides with the side surface of the connector outer side, that is, the surface on which the first locking portion (not shown) and the second locking portion 52A are provided in the connector width direction.

  When the moving member 70 is in the fitting allowable position, the locked portion 71C of the moving member 70 is located between the first locking portion and the second locking portion 52A of the housing 50. At the fitting allowable position, the front end surface of the locked portion 71C faces the rear end surface of the first locking portion in the front-rear direction, so that the moving member 70 is moved forward relative to the moving member 70. Even if a force is applied, the front end surface of the locked portion 71C and the rear end surface of the first locking portion abut. That is, since the locked portion 71C and the first locking portion are locked with each other when the locked portion 71C is moved in the forward direction, the moving member 70 is prevented from coming off forward.

  Further, when the moving member 70 is in the fitting allowable position, the second locking portion 52A having a front end surface formed as a tapered surface is positioned behind the locked portion 71C. That is, when the moving member 70 moves rearward toward the separation preventing position, the locked portion 71C has to get over the second locking portion 52A.

  When the moving member 70 moves to the separation preventing position, the second locking portion 52A having a rear end surface formed as a tapered surface is positioned in front of the locked portion 71C, so that the moving member 70 can be fitted. When moving forward toward the position, the locked portion 71C has to get over the second locking portion 52A.

  Next, how to use the thus configured cable connector 10 and board connector 40 will be described.

  First, as shown in FIG. 1 and FIGS. 3A to 3C, before the connector is fitted, the moving member 70 of the board connector 40 mounted on the circuit board (not shown) is in the forward position. That is, the cable connector 10 is inserted from above into the receiving recess 54 of the board connector 40 in the fitting allowable position, resulting in the connector fitting state shown in FIG. When the cable connector 10 is inserted, the contact portion 34 of the terminal 30 of the cable connector 10 and the contact portion 62 of the terminal 60 of the board connector 40 come into contact with each other, and the two connectors are electrically connected. Specifically, as shown in FIG. 6, the contact portion 62 of the terminal 60 enters between the winding portions 34 </ b> A of the pair of contact portions 34 of the terminal 30, and the winding portion 34 </ b> A is connected to the contact portion 62. And elastically press contact. In the present embodiment, when the contact portion 62 enters between the winding portions 34A, the curved portion of the winding portion 34A serves as an introduction portion, and the contact portion 62 is guided and interposed between the winding portions 34A. It is easy to enter.

  3B and 4B, in the connector fitting state, the contact portion 62 of the terminal 60 has a pair of terminals 30 so that the tip does not protrude from the upper surface of the terminal 30. Between the extended portions 35, that is, the holes 37. Thus, by making the dimension of the contact portion 62 in the fitting direction so that the tip of the contact portion 62 reaches the hole 37, the effective fitting length, that is, the connectors are completely fitted. A large distance in the fitting direction from the tip of the contact portion 62 in the combined state to the normal contact position between the contact portion 62 and the winding portion 34A of the terminal 30 can be secured. Thereby, in the connector fitting state, the contact position between the winding portion 34A of the cable connector 10 and the contact portion 62 of the board connector 40 is a normal contact when the connectors are completely fitted. Even if the position is slightly deviated from the position toward the distal end side of the contact portion 62, electrical conduction between the winding portion 34A and the contact portion 62 can be ensured. Therefore, even if there is a manufacturing error in the fitting direction of each part of the connector or an assembly error in the same direction of these parts, or even if the connector fitting state is incomplete, A stable contact state between the insertion portion 34 </ b> A and the contact portion 62 can be ensured.

  Further, in the connector fitting state, even if an inadvertent external force acts on the contact portion between the winding portion 34A and the contact portion 62, the effective fitting length is ensured to be large. Does not easily occur, and a stable contact state between the terminals can be favorably maintained.

  In the present embodiment, in the connector fitting state, the tip of the contact portion 62 does not protrude from the upper surface of the terminal 30. Alternatively, the tip of the contact portion 62 may protrude from the upper surface of the terminal 30. Good. In this case, a collision between the tip of the contact portion 62 and the inner surface is avoided by providing a hole or a recess allowing entry of the tip of the contact portion 62 on the inner surface of the terminal hole 21 of the housing 20. It becomes possible to do.

  In the connector fitting state, the regulated portion 36 of the terminal 30 of the cable connector 10 enters the receiving portion 64 of the terminal 60 of the board connector 40, and the rear surface of the regulated portion 36 is the regulating portion 62A of the terminal 60. It faces the front of the.

  Next, the moving member 70 is moved backward to perform locking to prevent the cable connector 10 from being detached. When an operation force is applied to the moving member 70 by the operator applying a backward operation force with a finger, the moving member 70 has the locked portion 71 </ b> C of the moving member 70 engaged with the second locking of the housing 50. The vehicle moves over the portion 52A and moves backward, and is brought to the separation preventing position as shown in FIG.

  When the moving member 70 is brought to the separation preventing position, the first lock portion 71A-1 of the moving member 70 is located above the first locked portion 20A of the cable connector 10 and the second lock portion 71A-2 of the moving member 70. Is positioned above the second locked portion 20B of the cable connector 10, whereby the locking to the cable connector 40 is completed. That is, even if an inadvertent upward force acts on the cable connector 10, the first lock portion 71A-1 is locked with the first locked portion 20A in the connector release direction, and the second lock When the portion 71A-2 is engaged with the second locked portion 20B in the connector detaching direction, the detachment of the cable connector 10 is prevented.

  When the cable connector 10 is desired to be detached from the board connector 40, the movable member 70 is moved forward and returned, and the movable member 70 is brought to the original fitting allowable position to release the lock. Thereafter, the cable connector 10 may be pulled upward from the board connector 40.

  In the present embodiment, the rear surface of the regulated portion 36 of the terminal 30 of the cable connector 10 faces the front surface of the regulating portion 62A of the terminal 60 of the board connector 40 in the connector fitting state. When an inadvertent force is exerted on the rear surface, the rear surface of the restricted portion 36 that has moved rearward comes into contact with the front surface of the restricting portion 62A, so that further movement of the restricted portion 36 to the rear is restricted. Is done. As a result, the terminal 30 of the cable connector 10 is prevented from coming off.

  Further, the restricted portion 36 is formed as a part of the metal terminal 30 and can be increased in strength, and an unintentional large force acts on the cable C backward, Even if it comes into contact with the restricting portion 62A formed as a part of the terminal 60, the restricted portion 36 can be sufficiently tolerated, and the terminal 30 can be prevented from being deformed or damaged. Further, the restricting portion 62A is formed as a part of the metal terminal 60 and has sufficient strength in the same manner as the restricted portion 36. Therefore, the restricting portion 62A is brought into contact with the restricted portion 36. There is no deformation or damage.

  In the present embodiment, the regulated portion 36 connects a pair of extending portions 35 located on both sides of the regulating portion 62A in the width direction, and therefore, as shown in FIG. , The regulated portion 36 extending in the width direction (left-right direction in FIG. 6) and the regulating portion 62A extending in the fitting direction (vertical direction in FIG. 6) intersect each other. Therefore, when an inadvertent force is applied to the cable C in the rearward direction, the rear surface of the regulated portion 36 and the regulating portion 62A can be obtained even if there is a slight misalignment between the terminal 30 and the terminal 60 in the width direction and the fitting direction. The front surface of the is securely abutted. As a result, the movement of the restricted portion 36 to the rear is restricted by the restricting portion 62A, and the terminal 30 of the cable connector 10 is reliably prevented from coming off.

  Further, in the present embodiment, the front end portion of the extending portion 35 is bent downward, that is, in the fitting direction, and the regulated portion 36 connects the front end portions of the extending portion 35 to each other. Since the rear surface of the restricted portion 36 extending in the fitting direction is formed by a plate surface of a metal plate, the restricted portion 36 is increased by increasing the size of the restricted portion 36 in the width direction and the fitting direction. The rear surface area can be increased. Thereby, the contact area between the rear surface of the locked portion 36 and the front surface of the restricting portion 62A can be increased. As a result, even if the terminal 30 and the terminal 60 are misaligned in the width direction and the fitting direction, the terminal 30 of the cable connector 10 is more reliably prevented from coming off.

  Further, as shown in FIG. 3B, in the connector fitting state, most of the terminals 60 of the board connector 40 in the fitting direction, that is, the connector height direction, are the terminals 30 of the cable connector 10. Located within range. As a result, the height of the connector assembly 1 is reduced.

  In the present embodiment, in the connector fitting state, as shown in FIG. 3B, the caulking portion 32A, the crimping portion 32B, the locking portion 33, the contact portion 34, and the board connector 40 of the cable connector 10 are provided. The attached portion 63 and the connecting portion 65 are sequentially located forward, and these portions are provided at non-overlapping positions in the front-rear direction. If these parts are provided at overlapping positions in the front-rear direction, each part cannot be provided at the overlapping position in the height direction, so it is necessary to provide the parts shifted in the fitting direction, that is, the connector height direction. . As a result, the height dimension of the connector assembly becomes large.

  In the present embodiment, since these portions are provided at non-overlapping positions in the front-rear direction, it is not necessary to shift each portion in the height direction, and the connector assembly 1 can be reduced in height. In the connector of the present embodiment, there is a great demand for space saving in the height direction, that is, a reduction in height, but there is room in the space in the direction in which the cable C extends, that is, in the front-rear direction. There is no problem even if the size of the connector assembly 1 in the front-rear direction is slightly increased by providing it at the overlapping position.

  In this embodiment, as is often seen in FIG. 6, the lower end of the contact portion 34 of the board connector 10 is curved to form the winding portion 34A. Instead, this is shown in FIG. Thus, it is good also as a form which this lower end extended toward the downward direction, without curving the lower end of a contact part. In the modification shown in the figure, the contact portion 34 ′ is dimple-processed on the outer plate surface in the width direction (left-right direction in FIG. 7), and a recess 34 ′ A is formed on the plate surface. At the same time, a protrusion 34 ′ B protruding inward in the width direction is formed on the plate surface on the inner side in the width direction. In the connector fitting state, the pair of contact portions 34 ′ is elastically pinched and contacted with the contact portion 62 of the terminal 60 at the protrusion 34 ′, so that a large contact pressure with the contact portion 62 is ensured.

  In the present embodiment, the terminal 30 of the cable connector 10 has a pair of extending portions 35 that extend forward and a regulated portion 36 that connects the front end portion of the extending portion 35. Instead, the terminal of the cable connector may have one plate-like extension portion extending forward and a restricted portion extending downward from the front end portion of the extension portion. The regulated portion can be easily formed by bending the front end portion of the extending portion downward. Also according to this modification, the rear surface of the restricted portion faces the front surface of the restricting portion of the board connector, so that the restricted portion can be formed with a large size in the width direction and a size in the fitting direction. Therefore, when an inadvertent force is applied to the cable in the rearward direction, the rear face of the restricted part and the front face of the restricting part are reliably applied even if there is a slight displacement of the terminal in the width direction and the fitting direction. Touch. As a result, the movement of the restricted portion to the rear is restricted by the restriction portion, and the terminal 30 of the cable connector 10 is reliably prevented from coming off.

  In the present embodiment, the restricting portion 62A is formed as a part of the contact portion 62 of the terminal 60 of the board connector 40. Instead, the restricted portion is separate from the contact portion in the board connector. It may be formed as a part.

  In the present embodiment, the fitting direction of the board connector 10 and the cable connector 40 is a direction perpendicular to the circuit board. However, the fitting direction is not limited to this, and the angle is with respect to the circuit board. The connectors may be fitted together.

<Second embodiment>
In this embodiment, the terminal of the cable connector is provided on the cable connector in a posture in which the base of the terminal is positioned on the lower side. It is different from the first embodiment provided in the cable connector in the positioned state. This embodiment, in combination with the first embodiment, widens the range of selection regarding the terminal holding direction, thereby improving the usability of the cable connector. Hereinafter, the present embodiment will be described focusing on differences from the first embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  FIG. 8 is a perspective view of the terminal 30 of the cable connector (not shown) and the terminal 60 of the board connector (not shown) according to the present embodiment as seen from the rear, and FIG. (B) shows the state after connector fitting. FIG. 9 is a perspective view of the terminal 30 of the cable connector (not shown) according to the present embodiment as viewed from the front. FIG. 10 is a cross-sectional view taken along the line XX of FIG. 8B and shows a cross section at the position of the contact portion between both terminals in the front-rear direction.

  The cable connector in the present embodiment has a housing (not shown) and terminals 30 as in the first embodiment. The terminal 30 itself has the same shape as the terminal 30 in the first embodiment, but the terminal 30 is turned upside down, that is, the base 31 is positioned on the lower side (FIG. 8A). , (B) and FIG. 9) are different from the first embodiment in that they are held in the housing.

  In the present embodiment, a pair of caulking portions 32A, a crimping portion 32B, and a locking portion 33 extend upward from the base portion 31 extending in the front-rear direction. In addition, the pair of contact portions 34 is connected to the front end portion of the locking portion 33 and extends forward, and the upper end of the front portion is curved so as to be wound inward in the width direction which is the opposing direction of the contact portions 34. A winding portion 34A is provided. Therefore, the curved portion of the winding portion 34A is positioned upward. As is often seen in FIG. 10, the front end portions of the winding portions 34 </ b> A are bent in a direction in which the front end portions are separated from each other, and the distance between the front end portions is increased. In this way, by expanding the introduction portion of the contact portion 62 of the terminal 60 of the board connector between the tip portions, the contact portion 62 enters between the winding portions 34A when the connector is fitted. It has become easier.

  Moreover, a pair of extension part 35 is extended toward the front from the front part of the base 31, and the front-end part is bent upwards. The regulated portion 36 is in a state where the front end portions of the extending portion 35 are connected to each other and extends in the width direction (see FIG. 9).

  The housing (not shown) of the present embodiment has the same outer shape as the housing 20 of the first embodiment, and the board connector (not shown) of the present embodiment is the same as that of the first embodiment. It has basically the same configuration as the board connector 40. Further, as shown in FIGS. 8 and 10, the connection portion 65 of the terminal 60 of the board connector is formed by bending the lower end of the terminal 60 in the direction opposite to that of the first embodiment. Has been.

  When the connector is fitted, the cable connector is fitted into the receiving recess of the board connector from above. When the cable connector is inserted, the contact portion 62 of the terminal 60 of the board connector enters between the pair of extending portions 35, that is, into the hole portion 37 and further between the winding portions 34 from below, The cable connector and the board connector are brought into a fitted state (see FIGS. 8B and 10).

  In the connector fitting state, as is often seen in FIG. 10, the pair of winding portions 34 </ b> A is elastically pinched with the contact portion 62 by a convex portion protruding inward in the opposing direction of the winding portions 3 </ b> A. In this way, the cable connector and the board connector are electrically connected. In the connector fitting state, as is often seen in FIG. 10, the rear surface of the regulated portion 36 of the cable connector terminal 30 faces the front surface of the regulating portion 62 </ b> A of the terminal 60 of the board connector.

  Therefore, in the case where it is required to provide the terminal 30 on the cable connector with the base 31 positioned at the lower side, according to the present embodiment, the rear surface of the restricted portion 36 in the connector fitting state. Is opposed to the front surface of the restricting portion 62A, so that when a rearward careless force acts on the cable, the rear surface of the restricted portion 36 that has moved rearward contacts the front surface of the restricting portion 62A. Thus, the further movement of the restricted portion 36 to the rear is restricted. As a result, disconnection of the terminal 30 of the cable connector is prevented.

  Also in the present embodiment, as in the first embodiment, the restricted portion 36 connects a pair of extending portions 35 located on both sides of the restricting portion 62A in the width direction. 10, when viewed in the front-rear direction, the restricted portion 36 extending in the width direction (left-right direction in FIG. 10) and the restriction portion 62A extending in the fitting direction (up-down direction in FIG. 10) Intersect. Therefore, when an inadvertent force is applied to the cable in the rearward direction, even if the terminal 30 and the terminal 60 are slightly misaligned in the width direction and the fitting direction, the rear surface of the regulated portion 36 and the regulating portion 62A The front face comes into contact securely. As a result, the movement of the restricted portion 36 to the rear is restricted by the restricting portion 62A, and the terminal 30 of the cable connector is reliably prevented from coming off.

<Third embodiment>
In the third embodiment, the front portion of the base portion of the terminal of the cable connector is bent forward and obliquely forward, and the extension portion extends forward from the bent portion and the extension portion is fitted. The extension portion extends forward from the front portion of the base portion at the same position as the base portion in the fitting direction because it is not bent in the mating direction, and the front end portion of the extension portion is bent in the fitting direction. This is different from the first embodiment. Since the basic configurations of the cable connector and the board connector according to the present embodiment are the same as those of the first embodiment, different points will be mainly described. The same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  FIG. 11 is a perspective view of the terminal 30 ′ of the cable connector and the terminal 60 of the board connector according to the present embodiment as viewed from the rear. FIG. 11A shows a state before the connector is fitted, and FIG. The state after the combination is shown. FIG. 12 is a perspective view of the terminal 30 ′ of the cable connector according to the present embodiment as viewed from the front. FIG. 13 is a cross-sectional view taken along the line XIII-XIII of FIG. 11B, showing a cross section at the position of the contact portion between both terminals in the front-rear direction.

  In this embodiment, as is often seen in FIGS. 11 and 12, the front portion of the base portion 31 ′ is bent forward and obliquely forward, and the extending portion 35 ′ forms a pair of arm pieces and The bent portions extend in parallel to each other and forward. Further, the extending portion 35 ′ is not bent in the extending direction. The regulated portion 36 ′ extends in the width direction with the front end portions of the extending portion 35 ′ being connected to each other. That is, as shown in FIGS. 11A, 11B, and 12, the extending portion 35 ′ and the regulated portion 36 ′ are connected to the terminal of the board connector on the metal plate forming the terminal 30 ′. It is formed by providing a slit-shaped hole 37 ′ extending in the front-rear direction that allows the 60 contact portions 62 to enter.

  When the cable connector is inserted into the board connector, the contact portion 62 of the terminal 60 enters between the winding portions 34A ′ from below and further enters the hole portion 37 ′ from below (FIG. 11B). And FIG. 13).

  In the connector fitting state, the tip of the contact portion 62 protrudes upward from the hole portion 37 '. The tip is located at the same position as or below the position of the upper surface of the base 31 'in the fitting direction. As is often seen in FIG. 13, the pair of winding portions 34 </ b> A ′ is elastically pinched and contacted with the contact portion 62 at the convex portion protruding inward in the opposing direction, whereby the cable connector and the board The connector is electrically connected. Further, as is often seen in FIG. 13, the rear surface of the regulated portion 36 'of the terminal 30' of the cable connector faces the front surface of the regulating portion 62A of the terminal 60 of the board connector.

  Also in the present embodiment, as in the first embodiment, the rear surface of the regulated portion 36 'of the terminal 30' of the cable connector faces the front surface of the regulating portion 62A of the terminal 60 of the board connector in the connector fitting state. Therefore, when an inadvertent force is applied to the cable in the rearward direction, the rear surface of the restricted portion 36 ′ that has moved rearward comes into contact with the front surface of the restricting portion 62 </ b> A. Further movement of the part 36 'is restricted. As a result, the terminal 30 'of the cable connector is prevented from coming off.

  In the present embodiment, since the front portion of the base portion 31 ′ of the terminal 30 ′ is bent forward and obliquely downward, the hole portion 37 ′ is the same as that of the first embodiment in which the front portion of the base portion 31 is not bent. Located below the case. Therefore, in the connector fitting state, the tip end portion of the contact portion 62 of the terminal 60 is likely to protrude from the hole portion 37 ′ with a sufficient amount of protrusion. As a result, as shown in FIG. 13, when viewed in the front-rear direction, the restricted portion 36 ′ extending in the width direction (left-right direction in FIG. 13) and the fitting direction (up-down direction in FIG. 13) extend. The restriction portion 62A can be reliably crossed. Therefore, when an inadvertent force is applied to the cable in the rearward direction, the rear surface of the restricted portion 36 ′ and the restricting portion even if the terminal 30 ′ and the terminal 60 are slightly misaligned in the width direction and the fitting direction. The front surface of 62A abuts securely. As a result, the rearward movement of the restricted portion 36 'is restricted by the restricting portion 62A, and the cable connector terminal 30' is reliably prevented from coming off.

  In addition, although the form which controls more reliably the movement of the to-be-restricted part 36 'to back by making the front-end | tip of the said contact part 62 protrude from said hole part 37' was demonstrated here, Even if the tip does not protrude from the hole 37 ′, the tip is positioned within the thickness range of the restricted portion 36 ′ in the fitting direction, and the front surface of the restricting portion 62A is the rear surface of the restricted portion 36 ′. It goes without saying that the movement of the restricted portion 36 'to the rear can be restricted by the restricting portion 62A as long as it is at the opposite position.

  As described above, in this embodiment, the front portion of the base portion 31 ′ of the terminal 30 ′ is bent forward and obliquely downward. Further, when in the connector fitting state, the front end portion of the contact portion 62 ′ of the terminal 60 ′ is fitted to the upper surface of the front portion of the base portion 31 ′ that contacts the flat inner surface of the terminal hole of the housing. In the same direction) or below.

  Temporarily, the front part of base 31 'is not bent as mentioned above, and extension part 35' which does not have a bent part extends ahead in the same position in the fitting direction with the above-mentioned upper surface of base 31 '. Even in this case, in order to reliably restrict the movement of the restricted portion 36 ′ by the restricting portion 62 A, the tip end portion of the contact portion 62 ′ is the upper surface of the extending portion 35 ′. It is preferable to protrude above the position of the upper surface of the base portion 31 ′. Therefore, in order to prevent the front end portion of the contact portion 62 ′ from colliding with the inner surface of the terminal hole of the housing, a hole or a recess allowing the front end portion to enter is additionally provided on the inner surface of the terminal hole. Need to form.

  In the present embodiment, the tip portion does not protrude above the upper surface of the base portion 31 ′ in the fitting direction, so there is no need to provide such a hole or a recess, and the terminal hole is correspondingly reduced. It becomes a simple shape and the manufacture of the housing becomes easy.
