Description

  The present invention relates to a connector that can be fitted to a board connector fixed to an upper surface of a board by soldering.

2. Description of the Related Art Conventionally, a board connector in which a pair of fixing brackets is mounted on both left and right side surfaces of a hood portion is known. The board connector is fixed to the upper surface of the board by soldering a fixing bracket to the board. On the other hand, in a connector that can be fitted into the inside of the hood portion of the board connector, an electric wire is generally drawn out behind the housing. If the electric wire is swung up and down with this connector fitted inside the hood portion, the hood portion tends to move upward, and stress concentrates on the soldered portion. Therefore, in the connector described in Patent Document 1 below, a restricting portion that is locked to the lower surface of the substrate when fitted is provided, and the stress applied to the soldered portion is reduced by receiving a stress on the restricting portion. Yes.
JP 2005-317357 A

  However, since the connector has a configuration in which the restricting portion is locked to the lower surface of the substrate when the connector is fitted to the substrate connector, the operation force is increased. That is, since it is necessary to complete the fitting between the connectors and the locking of the restricting portion in one action, the fitting operation force is increased. Further, when the electric wire is shaken up and down, the stress applied to the soldering portion can be reduced by the restricting portion. However, for example, when the electric wire is shaken left and right, the stress applied to the soldering portion cannot be reduced.

  The present invention has been completed based on the above circumstances, and an object thereof is to reduce a fitting operation force and a stress applied to a soldered portion.

  The present invention relates to a connector that can be fitted to a board connector in which the outer peripheral lower surface of the hood part is fixed to the upper surface of the board by soldering, and is a housing that fits inside the hood part when fitted. Between the initial position and the mating position with respect to the housing, and after the housing is fitted into the hood portion at the initial position, the housing is pushed into the mating position and fitted into the hood portion. It is characterized in that the slider is in contact with the upper surface of the outer periphery of the hood portion and the lower surface of the substrate at the joint position.

  According to such a configuration, the slider can be pushed from the initial position to the fitting position after the housing is fitted inside the hood portion with the slider set at the initial position. That is, the fitting operation force can be reduced because the fitting of both connectors and the pushing of the slider can be performed in two actions.

  Further, when the electric wire drawn out from the housing is shaken up and down, the housing tends to move upward, and the slider tends to move upward via the hood portion. However, since the slider is in contact with the lower surface of the substrate, the upward movement of the slider is restricted and the upward movement of the hood portion is restricted. Therefore, the stress applied to the soldered portion can be reduced.

The following configuration is preferable as an embodiment of the present invention.
A structure provided with a protruding protrusion that protrudes upward from a surface that contacts the lower surface of the substrate in the slider and that locks in a moving direction of the slider with respect to a concave portion provided on the lower surface of the substrate when in the mating position It is good.
According to such a configuration, the movement of the slider at the fitting position to the initial position is restricted by the locking protrusion engaging with the recess. Therefore, the slider can be held at the fitting position, and the stress applied to the soldered portion can be reduced.

The slider may be configured to contact the outer peripheral side surfaces of the hood portion at the fitting position, and the locking protrusions may be locked to the concave portions in the contact direction of the slider and the outer peripheral side surfaces of the hood portion.
According to such a configuration, when the electric wire is swung left and right, the housing tries to move in the left and right direction relative to the board, and the slider moves in the left and right direction relative to the board through the hood portion. try to. However, since the locking projection is locked in the left-right direction (the contact direction between the slider and the outer peripheral side surfaces of the hood) with respect to the concave portion of the substrate, the slider moves in the left-right direction relative to the substrate. And the movement of the hood portion in the left-right direction relative to the substrate is restricted. Therefore, the stress applied to the soldered portion can be reduced.

The fitting direction of the housing and the moving direction of the slider may be the same.
According to such a configuration, the slider can be easily moved continuously after the housing is fitted inside the hood portion.

The slider may be provided with a cutout portion that accommodates the end portion of the substrate at least at the fitting position.
According to such a configuration, it is not necessary to provide a notch or the like on the substrate side in order to avoid interference between the end portion of the substrate and the slider.

The notch may be configured to accommodate the end of the substrate at the initial position.
According to such a configuration, it can be avoided that the end portion of the substrate and the slider interfere with the movement of the slider.

The slider may be configured to include a holding projection that is locked to the housing in the moving direction of the slider.
According to such a configuration, the slider can be held at the initial position by the holding protrusion. Therefore, it is not necessary to hold the slider in the initial position by hand when the two connectors are fitted.

  According to the present invention, the fitting operation force can be reduced, and the stress applied to the soldered portion can be reduced.

  As shown in FIG. 9, the terminal holding part 33 has a horizontally long block shape that is long in the left-right direction. The terminal holding portion 33 holds a plurality of terminals 32 that are arranged in the left-right direction in two upper and lower stages. Among these terminals 32, a small terminal 32A is arranged at the center in the left-right direction, and large terminals 32B larger than the small terminals 32A are arranged on both sides in the left-right direction. Specifically, four large terminals 32B and three small terminals 32A are arranged on the upper side, and four large terminals 32B and nine small terminals 32A are arranged on the lower side.

  The small terminals 32A are not arranged on the upper stage side corresponding to the four small terminals 32A arranged at the center on the lower stage side and the one small terminal 32A arranged on the right end of the lower stage side. An entry space into which the lock arm 20 provided in the first connector 10 enters when the connectors 10 and 30 are fitted together is formed on the upper stage side corresponding to the small terminal 32A at the center on the lower stage side. The entry space is provided with a lock portion 39 that is engaged with the lock arm 20 and holds the connectors 10 and 30 in a properly fitted state.

  Further, on the upper stage side corresponding to the small terminal 32A at the lower right end, a misassembly prevention rib 38 is provided to prevent the connectors 10 and 30 from being assembled in an upside down posture. In addition, a pair of guide ribs 40 are provided along the front-rear direction on both the left and right sides of the lock portion 39 to guide when the connectors 10 and 30 are fitted together.

  The terminal 32 is held in a state of passing through the terminal holding portion 33 in the front-rear direction. That is, the terminal holding portion 33 is formed with a press-fitting hole (not shown) for press-fitting the terminal 32 in the front-rear direction, and the terminal 32 is press-fitted into the press-fitting hole. Is held by the terminal holding portion 33. The front end side of the terminal 32 is configured to protrude forward from the terminal holding portion 33. The front end of the terminal 32 is located behind the front edge of the hood portion 34. On the other hand, as shown in FIG. 10, the rear end side of the terminal 32 extends rearward from the terminal holding portion 33, is then bent downward toward the upper surface of the printed circuit board P, and is further rearward on the upper surface of the printed circuit board P. After being bent, the printed circuit board P extends rearward along the upper surface. That is, a portion of the terminal 32 that extends rearward along the upper surface of the printed circuit board P is soldered to a connection land (not shown) provided on the upper surface of the printed circuit board P. The connection land is connected to be conductive. The rear end side of the terminal 32 is protected while being covered from both sides in the left-right direction by a pair of protective walls 37 provided at the rear portion of the second housing 31.

  As shown in FIG. 9, the hood portion 34 is configured to extend forward from the outer peripheral edge portion of the terminal holding portion 33. Specifically, the hood portion 34 connects a bottom wall 34A that contacts the top surface of the printed circuit board P, a pair of side walls 34B that rises upward from both lateral edges of the bottom wall 34A, and top edges of the side walls 34B. And a ceiling wall 34C. Both the lock portion 39 and the guide rib 40 are provided at the center in the left-right direction on the inner surface of the ceiling wall 34C. Further, as shown in FIG. 10, the protective wall 37 is provided so as to protrude rearward from the side wall 34B.

  As shown in FIG. 10, the mounting groove 35 is formed through the side wall 34B in the vertical direction. On the other hand, the substrate fixing portion 36 is formed by punching a metal plate into a predetermined shape and performing bending or the like. The board fixing part 36 includes a main body part 36A having a substantially flat plate shape along the vertical direction, and a soldering part 36B protruding laterally from the lower end of the main body part 36A along the left-right direction. For this reason, the board | substrate fixing | fixed part 36 is formed in the substantially L shape seeing from the front-back direction as a whole. Among these, the soldering part 36B is soldered in a state of being placed on the fixed land of the printed circuit board P.

  Specifically, the mounting groove 35 includes a main body housing portion 35A into which the main body portion 36A of the board fixing portion 36 is inserted along the plate surface direction, and a soldering portion 36B along the direction perpendicular to the plate surface direction. It is comprised from the soldering part accommodating part 35B inserted. The soldering part accommodating part 35B is opened laterally toward the outer surface of the side wall 34B. Thus, the mounting groove 35 is provided within the thickness of the side wall 34B. Further, the substrate fixing portion 36 held inside the mounting groove 35 is also disposed within the plate thickness of the side wall 34B.

  As shown in FIGS. 1 to 3, a slit 36 </ b> C that opens downward is formed in the lower portion of the substrate fixing portion 36. The slit 36C divides the lower portion of the main body portion 36A and the soldering portion 36B into two parts in the front-rear direction. That is, the front leg portion 36F and the rear leg portion 36R are formed below the board fixing portion 36 with the slit 36C interposed therebetween. According to such a configuration, when the front edge of the hood portion 34 receives a force in a direction away from the upper surface of the printed circuit board P, the front leg portion 36F is first separated from the upper surface of the printed circuit board P by receiving the force. Acts on direction. On the other hand, in the rear leg portion 36R, the stress applied to the soldering portion 36B is reduced by opening and deforming the slit 36C. On the contrary, when the rear edge (terminal holding part 33) of the hood part 34 receives a force in a direction away from the upper surface of the printed circuit board P, the stress applied to the soldering part 36B of the front leg part 36F is reduced. The

  The first connector 10 has a first housing 11 made of synthetic resin. As shown in FIGS. 7 and 8, the first housing 11 has a horizontally long flat block shape that is long in the left-right direction. The first housing 11 can be fitted inside the hood portion 34. A plurality of cavities 12 are formed in the first housing 11 so as to penetrate in the front-rear direction. These cavities 12 are arranged side by side in the left-right direction in two steps, corresponding to the terminals 32 of the second connector 30.

  On the left side of the upper surface of the first housing 11 shown in FIG. 7, a detection groove 13 into which a misassembly prevention rib 38 enters when the connectors 10 and 30 are fitted is recessed along the front-rear direction. In addition, the lock arm 20 is formed in the front-rear direction at the center in the left-right direction on the upper surface of the first housing 11. Further, guide grooves 14 into which the guide ribs 40 enter when the connectors 10 and 30 are fitted are recessed along the front-rear direction on both sides of the lock arm 20 on the upper surface of the first housing 11 in the left-right direction.

  A box-shaped terminal (not shown) is accommodated in the cavity 12. The box terminal is composed of a small box terminal connected to the small terminal 32A and a large box terminal connected to the large terminal 32B. Along with this, the cavity 12 is also composed of a small cavity 12A for accommodating a small box-shaped terminal and a large cavity 12B for accommodating a large box-shaped terminal. The box-shaped terminal is held in the cavity 12 by a lance 15 formed inside the cavity 12 so as not to come off. The box terminal is connected to the end of an electric wire (not shown), and the electric wire is drawn out behind the cavity 12.

  As shown in FIG. 8, a pair of guide protrusions 16 extending in the front-rear direction are provided on the left and right side surfaces of the first housing 11. The guide protrusion 16 extends forward from the rear end portion of the first housing 11. The guide protrusion 16 enters the guide groove 41 that is recessed in the inner surface of the side wall 34 </ b> B of the hood portion 34 with the fitting of the connectors 10 and 30. Therefore, as shown in FIG. 6, in both connectors 10 and 30, both guide ribs 40 enter both guide grooves 14, misassembly prevention ribs 38 enter detection grooves 13, and both guide protrusions 16 are both guide guides 16. By entering the groove 41, the normal fitting state is stably guided. In FIG. 6, illustration of the internal structure of the first housing 11 is omitted for simplification of the drawing.

  As shown in FIG. 11, the slider 50 includes a frame-shaped main body 51 that has a substantially square frame shape, and a receiving portion 52 that protrudes forward in a cantilevered manner from the rear surface of the lower surface of the frame-shaped main body 51. Yes. The slider 50 is attached to the first housing 11 so as to be movable in the front-rear direction. Between the frame-shaped main body portion 51 and the receiving portion 52, a notch portion 56 in which an end portion of the printed board P is accommodated is formed. The notch 56 has substantially the same size as the thickness of the printed board P.

  The frame-shaped main body 51 is composed of a large-diameter portion 53 disposed substantially on the first half side and a small-diameter portion 54 disposed substantially on the second half side. The large-diameter portion 53 includes a pair of side walls 53A that are disposed to face each other in the left-right direction, and a ceiling wall 53B that connects upper edges of both side walls 53A. On the other hand, the small-diameter portion 54 includes a bottom wall 54A, a pair of side walls 54B that rise from both lateral edges of the bottom wall 54A, and a ceiling wall 54C that connects the upper edges of the side walls 54B. The ceiling wall 53B of the large-diameter portion 53 and the ceiling wall 54C of the small-diameter portion 54 are integrally formed with the upper and lower surfaces being flush with each other.

  The small diameter portion 54 is fitted on the outer peripheral surface of the first housing 11. Specifically, the small diameter portion 54 is in contact with the outer peripheral upper surface and the outer peripheral lower surface of the first housing 11 and both side surfaces of the both guide projections 16. On the other hand, the large diameter portion 53 is fitted on the outer peripheral surface of the hood portion 34. Specifically, the large-diameter portion 53 is in contact with the outer peripheral upper surface (the outer surface of the ceiling wall 34C) and the outer peripheral side surfaces (the outer surfaces of the both side walls 34B) of the hood portion 34. Thereby, the slider 50 can be moved in the front-rear direction between the initial position shown in FIG. 4 and the fitting position shown in FIG.

  A pair of holding grooves 16 </ b> A are cut out in the vertical direction on both side surfaces of both guide protrusions 16. On the other hand, as shown in FIG. 12, a pair of holding projections 58 are formed on the inner surface of both side walls 53A of the large-diameter portion 53 so as to protrude. As shown in FIG. 4, both holding protrusions 58 are fitted into both holding grooves 16A when the slider 50 is in the initial position. As a result, the slider 50 is held at the initial position.

  A step surface 55 is formed between the inner surface of the large diameter portion 53 and the inner surface of the small diameter portion 54. As shown in FIG. 5, the step surface 55 contacts the front edge of the hood portion 34 when the slider 50 is in the fitting position. Thereby, when the slider 50 is moved from the initial position to the fitting position, the slider 50 can be positioned at the fitting position.

  On the upper surface of the receiving portion 52 (the lower surface constituting the notch portion 56), a locking projection 57 is provided so as to protrude upward. The locking projection 57 includes a guide surface 57A that is inclined upward as it goes rearward, a horizontal surface 57B that extends horizontally behind the guide surface 57A, and a vertical direction from the rear end of the horizontal surface 57B toward the upper surface of the receiving portion 52. And a vertical surface 57 </ b> C that descends downward. As shown in FIG. 11, the locking projection 57 is formed in a horizontally long shape over substantially the entire length of the second housing 31 in the left-right direction.

  On the other hand, the printed board P is formed with a locking hole (an example of the “concave portion” of the present invention) H that can receive the locking projection 57 penetrating in the plate thickness direction. Of the inner surface of the locking hole H, the surface on the end side of the printed circuit board P is a front and rear locking surface H1 extending in the vertical direction. The front / rear locking surface H1 can be locked with the vertical surface 57C of the locking projection 57 in the front / rear direction, that is, the moving direction of the slider 50 when the slider 50 is in the fitting position. Accordingly, the slider 50 is held at the fitting position and is restricted from moving to the initial position.

  Of the inner surface of the locking hole H, the left and right side surfaces are left and right locking surfaces H2 extending in the vertical direction. As shown in FIG. 6, the left and right locking surfaces H <b> 2 can be locked in the left and right direction with the left and right side surfaces 57 </ b> D of the locking projection 57. As a result, the slider 50 is restricted from moving relative to the printed circuit board P in the left-right direction at the fitting position.

  The present embodiment is configured as described above, and its operation will be described subsequently. First, as shown in FIG. 1, the slider 50 is set to an initial position. When the slider 50 is set to the initial position, as shown in FIG. 4, both the holding projections 58 are fitted inside the both holding grooves 16A and locked in the front-rear direction, so that the slider 50 is held at the initial position.

  Next, the connectors 10 and 30 are fitted together. When the first housing 11 is fitted inside the hood portion 34, as shown in FIG. 2, both the connectors 10 and 30 reach the normal fitting state, and the lock arm 20 is locked to the lock portion 39. Thus, both connectors 10 and 30 are held in a properly fitted state. At this time, the end portion of the printed circuit board P is accommodated in the cutout portion 56. Thereby, when pushing the slider 50 from an initial position to a fitting position, it can avoid that the edge part of the printed circuit board P and the front end of the receiving part 52 interfere.

  Moreover, in the normal fitting state of both the connectors 10 and 30, as shown in FIG. 4, the front edge part of the hood part 34 is shallowly fitted inside the large diameter part 53. Due to this shallow fitting, both side walls 53A of the large-diameter portion 53 (both inner peripheral side surfaces of the large-diameter portion 53) are in contact with both side walls 34B of the hood portion 34 (both outer peripheral side surfaces of the hood portion 34). Thereby, when pushing the slider 50 from an initial position to a fitting position, it can avoid that the front end of both the side walls 53A of the large diameter part 53 interferes with the front end of the both side walls 34B of the hood part 34.

  Next, the slider 50 is pushed from the initial position to the fitting position. Then, from the state of FIG. 2, the guide surface 57 </ b> A of the locking projection 57 is in sliding contact with the end portion of the printed circuit board P and the receiving portion 52 is bent and deformed downward, and the horizontal surface 57 </ b> B rides on the lower surface of the printed circuit board P. When the slider 50 is further pushed in, the receiving portion 52 is restored and the locking projection 57 is fitted into the locking hole H as shown in FIG.

  In parallel with this, both holding projections 58 shown in FIG. 4 are formed on the inner surfaces of both holding grooves 16A, and both side walls 54B of the small-diameter portion 54 are bent and deformed in both left and right directions, thereby constituting the front surfaces of both holding grooves 16A. It gets over both front ribs and enters the inside of both insertion grooves 16B arranged in front of both front ribs. Then, both side walls 54B of the small diameter portion 54 are restored, and when the slider 50 is further pushed in, the stepped surface 55 comes into contact with the front edges of the side walls 34B of the hood portion 34, and the slider 50 reaches the fitting position. When the slider 50 reaches the fitting position, the front edge portion of the hood portion 34 is deeply fitted inside the large diameter portion 53.

  On the other hand, as shown in FIG. 3, the end portion of the printed circuit board P is accommodated in the notch 56, and the receiving portion 52 contacts the lower surface of the printed circuit board P. Further, when the vertical surface 57C of the locking projection 57 is locked in the front-rear direction with respect to the front-rear locking surface H1 of the locking hole H, the slider 50 is held in the fitting position. Further, as shown in FIG. 6, both side surfaces 57 </ b> D of the locking projection 57 are locked in the left-right direction with respect to the left and right locking surfaces H <b> 2 of the locking hole H, so The relative movement in the left-right direction is restricted.

  The reason why the fitting of both connectors 10 and 30 and the pushing of the slider 50 are divided into two actions as described above is to reduce the fitting operation force. That is, in order to fit both the connectors 10 and 30, a large fitting force is required due to the frictional resistance when the terminal 32 and the box-shaped terminal come into contact with each other. Combined operation force is required. In this respect, in the present embodiment, the fitting operation force can be reduced because the fitting of the connectors 10 and 30 and the pushing of the slider 50 are performed separately.

  In addition, since the fitting direction of the first connector 10 with respect to the second connector 30 and the pushing direction of the slider 50 are both forward and the same, the first connector 10 is continued after being fitted to the second connector 30. It is easy to push the slider 50. Further, since the slider 50 can be held at the fitting position by the locking projection 57 and the locking hole H, the slider 50 can be prevented from moving to the initial position unexpectedly.

  Now, a plurality of electric wires are pulled out behind the first connector 10, and the electric wires may be shaken up and down, left and right, or pulled backward. When the electric wire is shaken up and down, the first housing 11 receives an upward force and tries to move upward, and the slider 50 tries to move upward via the hood portion 34. At this time, since the movement of the slider 50 is restricted by the receiving part 52 coming into contact with the lower surface of the printed circuit board P, the movement of the hood part 34 is also restricted. Therefore, the stress applied to the soldering portion of the soldering portion 36B can be reduced.

  When the electric wire is swung left and right, the first housing 11 receives a force in the left and right direction and tries to move in the left and right direction relative to the printed circuit board P, and the slider 50 moves via the hood portion 34. An attempt is made to move in the left-right direction relative to the printed circuit board P. At this time, as described above, since the slider 50 is restricted from moving in the left-right direction relative to the printed circuit board P, the hood portion 34 also moves in the left-right direction relative to the printed circuit board P. To be regulated. Therefore, the stress applied to the soldering portion of the soldering portion 36B can be reduced.

  In addition, when the electric wire is pulled backward, the first housing 11 receives the force backward and tries to move backward, and the hood portion 34 moves backward via the locking portion between the lock arm 20 and the lock portion 39. Try to move on. When the hood part 34 tries to move rearward, the slider 50 tries to move rearward through a contact portion between the front edge of the side walls 34B of the hood part 34 and the step surface 55. At this time, as described above, the rearward movement of the slider 50 is restricted by the engagement between the vertical surface of the engagement protrusion 57 and the front and rear engagement surfaces H1 of the engagement hole H. Backward movement is also restricted. Therefore, the stress applied to the soldering portion of the soldering portion 36B can be reduced.

  As described above, in the present embodiment, the fitting operation of both connectors 10 and 30 and the movement of the slider 50 are performed in two actions, so that the fitting operation force can be reduced. In addition, since the slider 50 is configured not to move relative to the printed circuit board P in the up / down direction, the left / right direction, and the front / rear direction, the hood portion 34 is arranged in the up / down direction, left / right direction, and front / rear direction with respect to the printed circuit board P. Therefore, the stress applied to the soldering portion of the soldering portion 36B can be reduced.

  Moreover, since the fitting direction of both the connectors 10 and 30 and the pushing direction of the slider 50 are made the same, the slider 50 can be pushed in continuously after fitting both the connectors 10 and 30. Further, since the notch 56 is provided on the slider 50 side, the notch or the like may not be provided on the printed circuit board P side. Further, since the end portion of the printed circuit board P is accommodated in the cutout portion 56 at the initial position, interference between the end portion of the printed circuit board P and the slider 50 due to the pushing of the slider 50 can be avoided. Further, since the slider 50 can be held at the initial position by fitting both the holding projections 58 and both holding grooves 16A, the slider 50 is held at the initial position by hand when the connectors 10 and 30 are fitted. There is no need.
