Description

  The present invention relates to a connector.

  Conventionally, in a wire-to-board connector for connecting an electric wire such as a cable to a circuit board such as a printed circuit board, a pair of combined bodies to which electric wires arranged in a row are connected are combined by a holder. There has been proposed a technique in which an electric wire connector is configured, and the electric wire connector is inserted into a housing of a board connector to be fitted (engaged) (see, for example, Patent Document 1). Thereby, the electric wires arranged in two rows can be connected to the circuit board.

  FIG. 14 is an exploded view of a conventional wire connector.

  In the figure, 811 is a pair of combined bodies to which electric wires 891 arranged in one row are connected, and is combined by a holder 831 in a state of facing each other, thereby constituting an electric wire connector. Each combined body 811 includes a plurality of terminal accommodating chambers 813, and terminals (not shown) connected to the tips of the electric wires 891 are accommodated in the terminal accommodating chambers 813. An electric wire locking portion 814 is formed at the upper end of the partition wall that partitions the adjacent terminal accommodating chamber 813.

  On the other hand, the holder 831 includes a pair of end walls 832 and a partition wall 833 that connects the end walls 832. On each end wall 832, protrusion pieces 836 a and 836 b and a locking protrusion piece 837 are formed.

  Then, each coupling body 811 is in such a posture that the opening of the terminal accommodating chamber 813 faces the partition wall 833, and the engaging protrusion 821 protruding from the side end surface is provided with a groove between the strip pieces 836a and 836b. By being engaged with the holder 831, the holder 831 is attached. In this case, the front side wall 834 protruding from the lower end of the partition wall 833 comes into contact with the lower end of the combined body 811, and the locking protrusion 837 locks the upper surface of the side end protrusion 822 of the combined body 811. Further, the protrusion 835 protruding from the upper end of the partition wall 833 enters between the adjacent wire locking portions 814.

  In this way, the electric wire connector configured by coupling the pair of coupled bodies 811 by the holder 831 is inserted into and fitted into the housing of the board connector (not shown). Thus, the two rows of electric wires 891 can be electrically connected to a circuit board (not shown) on which the board connector is mounted.

  In the figure, reference numeral 1 denotes an electric wire connector as a connector in the present embodiment, which is connected to a terminal end of a cable including a plurality of electric wires 91. Reference numeral 101 denotes a board connector as a mating connector in the present embodiment, which is mounted on a circuit board as a board (not shown). The board connector 101 is a so-called straight type connector, and is mounted in an upright state with respect to the circuit board, that is, in an open state facing upward. The electric wire connector 1 is vertically fitted to the board connector 101, whereby the electric wire 91 is pulled out perpendicular to the circuit board.

  Further, in the present embodiment, expressions indicating directions such as upper, lower, left, right, front, rear, etc. used for explaining the configuration and operation of each part of the wire connector 1 and the board connector 101 are absolute. The wire connector 1 and the board connector 101 are suitable when the wire connector 1 and the board connector 101 are in the posture shown in the figure, but the posture of the wire connector 1 and the board connector 101 is changed when the posture is changed. It should be interpreted according to changes.

  Here, the board connector 101 is a receptacle connector, which is integrally formed of an insulating material such as a synthetic resin, and includes a housing 111 as a connector body that fits with the wire connector 1, and a bottom plate of the housing 111. And a board-side terminal 161 as a counterpart terminal made of a metal rod-like member attached so as to penetrate the portion 112. The housing 111 is a substantially rectangular parallelepiped box-shaped member extending in the direction orthogonal to the fitting direction with the wire connector 1 and in the arrangement direction of the board-side terminals 161, that is, in the width direction of the board connector 101. It is.

  The bottom plate portion 112 is formed with a terminal insertion hole 116 penetrating the bottom plate portion 112, and the board-side terminal 161 is fitted into the terminal insertion hole 116, whereby the bottom plate portion 112 is inserted into the bottom plate portion 112. Installed. The board-side terminal 161 includes a solder tail part 162 that extends downward from the bottom plate part 112, is inserted into a through hole formed in the circuit board and is electrically connected by soldering or the like, and the terminal fitting. A main body part 163 fitted and held in the hole 116 and a contact part 164 extending upward from the bottom plate part 112 and contacting the electric wire side terminal 61 of the electric wire connector 1 are included.

  In the example shown in the figure, the board-side terminals 161 are arranged so that a total of 40 terminals are arranged in two rows at a pitch of 2.0 [mm], but the number of board-side terminals 161, that is, the number of poles And the pitch of the board | substrate side terminal 161 can be changed arbitrarily. Note that the board-side terminals 161 do not necessarily have to be fitted into all the terminal insertion holes 116, and the board-side terminals 161 can be omitted as appropriate in accordance with the arrangement of the wires 91 of the wire connector 1.

  The housing 111 includes a substantially rectangular flat plate-shaped bottom plate portion 112 and a pair of side plate portions 113 that extend along the long side of the bottom plate portion 112 and are erected from the bottom plate portion 112. Five surfaces are defined by a pair of end plate portions 114 extending along the short side of the bottom plate portion 112 and erected from the bottom plate portion 112, and the bottom plate portion 112, the side plate portion 113, and the end plate portion 114. A fitting space 115 having an open upper surface facing the portion 112 is provided. The wire connector 1 is inserted and fitted into the fitting space 115.

  1 and 2, the side plate 113 located on the near side, that is, the front side plate 113a has a lock opening 121 formed therein. The locking projection 121 provided in the electric wire connector 1 enters and engages with the locking opening 121. In addition, a bulge portion 122 for polarity is formed on the front side plate portion 113a, and a groove portion 122a for polarity is formed on the back side of the bulge portion 122 for polarity, that is, on the fitting space 115 side. And the convex part 22 for polarity with which the electric wire connector 1 is provided approachs and is engaged with this groove part 122a for polarity.

  1 and 2, the side plate portion 113 located on the back side, that is, the rear side plate portion 113b does not include the lock opening 121, the polar bulge portion 122, and the polar groove portion 122a. In terms of the point, it has the same configuration as the front side plate portion 113a. When the front side plate portion 113a and the rear side plate portion 113b are described in an integrated manner, they will be described as the side plate portion 113.

  Furthermore, the front side plate portion 113a and the rear side plate portion 113b protrude toward the rear side plate portion 113b and the front side plate portion 113a on the side of the fitting space 115, and the vertical direction, that is, the fitting direction with the electric wire connector 1. A ridge 118 extending in the direction is formed. Each of the protrusions 118 is formed at a position corresponding to each of the contact portions 164 of the board-side terminal 161 and extends along each of the contact portions 164. That is, as shown in FIGS. 2 to 4, the protruding portion 118 is located on the side surface of each contact portion 164.

  Further, it is desirable that the side end of the ridge 118, that is, the gap between the ridge of the ridge 118 and the side surface of the contact portion 164, is extremely small and may be zero. That is, it is desirable that the peak portion of the ridge 118 and the contact portion 164 are very close to each other, and may contact each other in some cases. Accordingly, when the wire connector 1 and the board connector 101 are fitted, the member of the wire connector 1 is prevented from entering between the protrusion 118 and the contact portion 164, and the contact portion 164 is damaged. There is nothing. Further, when the member of the electric wire connector 1 comes into contact with the contact portion 164 from a direction opposite to the protruding portion 118, the protruding portion 118 supports the contact portion 164 from behind, so that the electric wire connector 1 Even if force is received from the member, the contact portion 164 is not deformed. Accordingly, it is possible to reliably prevent the contact portion 164 of the board side terminal 161 from being damaged.

  Furthermore, it is desirable that the upper end surface of the protrusion 118 is located above the upper end of the contact portion 164, that is, closer to the fitting surface of the housing 111. Accordingly, when the wire connector 1 and the board connector 101 are fitted, the member of the wire connector 1 is prevented from coming into contact with the upper end of the contact portion 164, and the contact portion 164 of the board-side terminal 161 is damaged. There is no.

  A partition wall 117 is formed on the upper surface of the bottom plate 112 so as to protrude upward and extend in the longitudinal direction of the bottom plate 112. The partition wall 117 is located between the front plate portion 113a and the rear plate portion 113b, and extends in parallel with the front plate portion 113a and the rear plate portion 113b. Therefore, the fitting space 115 is divided into two in the short direction of the bottom plate portion 112 (the left-right direction in FIGS. 3 and 4) by the partition wall portion 117. Then, in a state in which the electric wire connector 1 and the board connector 101 are fitted, the partition wall portion 117 enters the central space 17 of the electric wire connector 1. Further, the upper surface of the bottom plate portion 112 is in contact with or close to the lower surface of the combined body 11 of the wire connector 1.

  In the example shown in the figure, the partition wall 117 is present not in the entire longitudinal range of the bottom plate portion 112 but only in a part of the range, and is lower than the front plate portion 113a and the rear plate portion 113b. However, the dimensions of the bottom plate portion 112 in the longitudinal direction and the height direction can be appropriately changed.

  On the other hand, the electric wire connector 1 is a plug connector, and is integrally formed with a pair of coupling bodies 11 integrally formed of an insulating material such as a synthetic resin and an insulating material such as a synthetic resin. A pair of holders 31 having the same shape for connecting both ends of the combined body 11 in the width direction, and a wire-side terminal 61 as a terminal loaded in the combined body 11 and connected to the vicinity of the terminal end of the electric wire 91; Have The pair of coupling bodies 11 extend in the direction orthogonal to the fitting direction with the board connector 101 and in the arrangement direction of the wires 91, that is, in the width direction of the wire connector 1 (width direction of the coupling body 11). 1 and 2, the front coupling body 11 a located on the near side in FIGS. 1 and 2 and the rear coupling body 11 b located on the back side in FIGS. 1 and 2.

  Then, the outer plate portion 16 of the front coupling body 11a is engaged with the locking projections 21 that enter and engage with the locking openings 121 of the board connector 101, and the engagement between the locking openings 121 and the locking projections 21. An operation projection 23 for releasing the lock and releasing the lock, and a polarity projection 22 that enters and engages with the polarity groove 122a of the board connector 101 are formed. The rear coupling body 11b does not include the locking projection 21, the operation projection 23, and the polarity projection 22, but has the same configuration as the front coupling body 11a in other respects. When the front combined body 11a and the back combined body 11b are described in an integrated manner, the combined body 11 will be described.

  Each combined body 11 accommodates a body portion 12 extending in the width direction thereof, i.e., the width direction of the wire connector 1, an outer plate portion 16 connected to the body portion 12, and a plurality of the wire-side terminals 61. Terminal receiving recess 13. In the example shown in the figure, 20 wire-side terminals 61 are arranged in a line in the width direction of the coupled body 11 at a pitch of 2.0 [mm], but the number of wire-side terminals 61, That is, the number of poles and the pitch of the electric wire side terminals 61 can be arbitrarily changed. Note that the electric wire side terminals 61 do not necessarily have to be accommodated in all the terminal accommodating recesses 13, and the electric wire side terminals 61 can be appropriately omitted in correspondence with the arrangement of the electric wires 91 of the electric wire connector 1.

  The terminal accommodating recess 13 includes a counterpart terminal accommodating portion 13 a that opens to the surface of the outer plate portion 16, and an electric wire accommodating portion 13 b that opens to the surface of the main body portion 12. The counterpart terminal accommodating portion 13a accommodates the contact portion 64 of the electric wire side terminal 61 therein, and includes a slit-like opening that continuously opens on the surface and the bottom surface of the outer plate portion 16. When the wire connector 1 and the board connector 101 are fitted, the contact part 164 of the board side terminal 161 and a part of the protrusion 118 of the housing 111 enter the counterpart terminal housing part 13a, and the board side terminal The contact portion 164 of 161 engages and contacts the contact portion 64 of the electric wire side terminal 61, and a part of the protruding portion 118 engages with the counterpart terminal accommodating portion 13a.

  Further, the electric wire accommodating portion 13b accommodates the connecting portion 65 of the electric wire side terminal 61 therein, and extends in the vertical direction opening on the surface of the main body portion 12, that is, in the fitting direction with the board connector 101. An elongated slit-like opening. Each electric wire 91 has a predetermined range from the terminal end accommodated in the electric wire accommodating portion 13b, and a portion in the vicinity of the terminal end of the range is connected to the connecting portion 65, from the electric wire accommodating portion 13b. It is in the state of extending behind the combined body 11, that is, in the anti-fitting direction.

  Between the front coupling body 11a and the rear coupling body 11b, both ends of which are coupled by the holder 31, are flat (flat) extending in the fitting direction with the board connector 101 and in the width direction of the wire connector 1. A central space 17 is formed. The central space 17 is a gap formed between the surface of the main body portion 12 of the front coupling body 11a and the surface of the main body section 12 of the rear coupling body 11b, and the electric wire connector 1 and the board connector 101 are fitted to each other. In this state, it is a gap into which the partition wall 117 of the housing 111 enters. As the partition wall 117 enters the central space 17, the distance between the front coupling body 11a and the rear coupling body 11b is kept constant, and the front coupling body 11a and the rear coupling body 11b in the fitting space 115 are maintained. Positioning in the thickness direction of the connector 101 is reliably performed.

  Further, projecting pieces 16 a are formed in the vicinity of both ends in the width direction of the electric wire connector 1 in the outer plate portion 16 of the combined body 11. The protruding piece 16a engages with the upper ends of the front plate portion 113a and the rear plate portion 113b of the housing 111 in a state where the electric wire connector 1 and the board connector 101 are fitted. Further, a flexible portion 16b that is partially separated from other portions by a slit is formed near the center of the outer side plate portion 16 in the width direction of the wire connector 1. The flexible portion 16 b can be easily elastically deformed in the thickness direction of the electric wire connector 1.

  Next, the configuration of the electric wire connector 1 will be described in more detail.

  FIG. 5 is an exploded view of the wire connector in the embodiment of the present invention, FIG. 6 is a top view of the wire connector in the embodiment of the present invention, and FIG. 7 is a perspective view of the front connector of the wire connector in the embodiment of the present invention. FIG. 8 is a five-side view of the front connector of the electric wire connector according to the embodiment of the present invention, and FIG. 9 is an enlarged view of the first main part of the front connector of the electric wire connector according to the embodiment of the present invention. FIG. 8 is an enlarged view of a portion C in FIG. 8, FIG. 10 is an enlarged view of a second main portion of the front connector of the electric wire connector in the embodiment of the present invention, and is an enlarged view of portion D in FIG. FIG. 12 is a perspective view of a pair of holders of the wire connector in the embodiment of the present invention, and FIG. 13 is a four-side view of the holder of the wire connector in the embodiment of the present invention. It is. 6, (a) is an overall view, (b) is an enlarged view of a portion B in (a), FIG. 8 (a) is a top view, (b) is a front view, and (c) is a front view. In FIG. 13, (a) is a front view, (b) is a top view, (c) is a side view, and (d) is a bottom view. It is.

  As shown in the drawing, a wire-side terminal 61 is accommodated at the lower end of each wire accommodating portion 13b that opens to the surface of the main body portion 12, and a wire-related member is disposed on both side walls of the upper end portion of each wire accommodating portion 13b. A stop 14 is formed. And the electric wire 91 accommodated in each electric wire accommodating part 13b is connected to the connection part 65 of the electric wire side terminal 61 in the vicinity of the terminal end, ie, the lower end, and the part corresponding to the upper end of the electric wire accommodating part 13b. Since it is locked by the wire locking portion 14, it is prevented from being detached from the wire housing portion 13b.

  The electric wire side terminal 61 is an integrally formed member made of a conductive metal plate, and as shown in FIG. 11, a main body portion 62 and a connecting portion connected to the upper end of the main body portion 62. 63, a contact portion 64 connected to both sides of the connecting portion 63, and a connecting portion 65 connected to the lower end of the main body portion 62 and the upper end of the connecting portion 63. The main body 62 is a substantially rectangular flat plate member extending in the vertical direction, that is, in the fitting direction with the board connector 101, and is held by the main body 12 in the electric wire housing portion 13b.

  Further, the contact portion 64 is a pair of elongated strip-like members bent substantially at right angles in the middle, and is an elongated plate-like contact extending in the vertical direction, that is, in the fitting direction with the board connector 101, facing each other. The arm part 64a and the contact convex part 64b formed in the front-end | tip of this contact arm part 64a, ie, a lower end, are included. The contact arm portion 64a can be elastically deformed, and the distance between the contact arm portion 64a and the contact convex portion 64b facing each other can be elastically extended. Therefore, when the wire connector 1 and the board connector 101 are fitted, the contact part 164 of the board-side terminal 161 that has entered the counterpart terminal housing part 13a is between the contact convex part 64b and the contact arm part 64a facing each other. Since it enters and widens the distance between the contact convex portion 64b and the contact arm portion 64a, the contact convex portion 64b and the contact arm portion 64a are elastically sandwiched from both sides. Thereby, the contact between the contact portion 164 of the board-side terminal 161 and the contact portion 64 of the wire-side terminal 61 is stably maintained, and the conduction state between the substrate-side terminal 161 and the wire-side terminal 61 is stably maintained. .

  The connecting portions 65 are a pair of flat plate members that are curved at substantially right angles toward the thickness direction of the board connector 101, specifically, toward the surface of the main body portion 12, each of which is a fork-shaped or tuning-fork. (S) shape. Each connection portion 65 includes a pair of connection arm portions 65a, a slit-like connection groove portion 65b formed between the opposing connection arm portions 65a, and a sharp point formed at the tip of each connection arm portion 65a. And an end portion 65c. When the electric wire 91 is pushed into the electric wire housing portion 13b from the surface side of the main body portion 12 toward the inner side of the electric wire housing portion 13b, the two locations near the lower end of the electric wire 91 are changed from the right side to the left side in FIG. And is pushed into the connection groove portion 65b of each connection portion 65. Here, the width of the connecting groove 65b is smaller than the outer diameter of the electric wire 91, and is set to a dimension equal to or smaller than the outer diameter of the core metal portion 91a of the electric wire 91. Therefore, when the electric wire 91 is pushed into the connection groove portion 65b, the insulating coating 91b that covers the periphery of the core metal portion 91a is broken by the sharp end portion 65c, and the exposed core metal portion 91a becomes the connection groove portion. It comes into contact with the connecting arm portions 65a on both sides of the 65b. As a result, the cored bar portion 91a is in direct contact with the connecting arm portion 65a and is reliably conducted, and the electric wire 91 is firmly held by the connecting arm portion 65a.

  Further, as shown in FIG. 9, an inclined lead-in portion 13d is formed at the lower end of the counterpart terminal accommodating portion 13a that opens to the surface of the outer side plate portion 16, and the lower end of the counterpart terminal accommodating portion 13a is tapered. It has a shape that is expanded in a shape. Therefore, when the wire connector 1 and the board connector 101 are fitted, the contact part 164 of the board-side terminal 161 and the protrusion 118 of the housing 111 can smoothly enter the counterpart terminal housing part 13a. There is no damage.

  At both ends of the coupling body 11, a coupling portion 25 for coupling to the holder 31 is formed so as to protrude outward in the width direction of the wire connector 1. The coupling part 25 is recessed from the surface side of the main body part 12 toward the surface side of the outer plate part 16, and the coupling groove part 25a extending in the vertical direction, that is, the fitting direction with the board connector 101, A connecting protrusion 25b that protrudes further outward from the connecting portion 25 in the width direction of the electric wire connector 1 and extends in the fitting direction with the board connector 101, and from the middle of the connecting protrusion 25b to the surface side of the main body 12 It includes a stop portion 25c extending toward the end, and an auxiliary protrusion 25d that defines an outer end in the width direction of the electric wire connector 1 of the coupling groove portion 25a and extends in the fitting direction with the board connector 101.

  On the other hand, the pair of holders 31 are separate members having the same shape. Each holder 31 includes a substantially rectangular flat plate-shaped back plate portion 31a, a pair of side plate portions 31b extending from both side edges of the back plate portion 31a and erected from the back plate portion 31a, A bottom plate portion 31c extending along the lower side edge of the back plate portion 31a and erected from the back plate portion 31a, and defining four surrounding surfaces by the back plate portion 31a, the side plate portion 31b and the bottom plate portion 31c. The substantially rectangular parallelepiped space is partitioned by a partition wall portion 33 extending in the vertical direction, that is, in the fitting direction with the board connector 101, thereby forming a pair of holding groove portions 32. Each holding groove 32 is a groove that opens to the front of the holder 31 and extends in the vertical direction.
