Problems to be solved by the invention

[0004] In recent years, with the miniaturization of various devices such as portable communication terminals, miniaturization of connectors is also required. As a result of the miniaturization of the connector, there is a problem that the male / female member of the connector cannot be securely connected! It was.

The male / female member is fitted / separated between the male and female members of the connector, but when the male and female members are smaller than the fingertip of the worker, the connector The work for fitting and separating the male member and the female member is performed. Also, with the miniaturization of the connector, the protrusions and engaging claws become smaller, It is also conceivable that the feeling of mushroom is recognized by the operator's fingertips.

If the male and female members of the connector are not reliably fitted, the electrical connection between the contacts will be impaired. For this reason, there is a demand for a mechanism that can reliably connect the male and female members of the connector and securely connect the contacts even if the connector is small.

[0005] The present invention has been made based on such a technical problem, and is an electrical connector assembly in which a male member and a female member of a connector can be securely fitted and contacts can be reliably connected. The purpose is to provide.

Means for solving the problem

[0006] An electrical connector assembly of the present invention made for the above purpose is an electrical connector assembly for electrically connecting a printed wiring board and an electric wire, and is a first fixed to the printed wiring board. A housing, a second housing that fits into the first housing, a first contact held in the first housing and electrically connected to the printed wiring board, and held in the second housing. A second contact connected to the first contact and the electric wire, and a slide member held in the second housing so as to be movable along the direction of pulling the second housing into the first housing. . In such an electrical connector assembly, when the first housing and the second housing are fitted together, the first contact and the second contact can be electrically connected. The printed wiring board and the electric wire are electrically connected through the contact and the second contact.

When the electrical connector assembly having such a configuration is incompletely fitted between the first housing and the second housing, the slide member is moved along the punching direction along the first housing. The second housing can be pressed by sliding to the ring side. As a result, it is possible to completely fit the first housing and the second housing.

Here, in order to fit the first housing and the second housing, a convex portion is formed on the first housing, and the second housing is engaged with the convex portion. A plate portion having an engaging claw can be formed. In such a configuration, when the first housing and the second housing are not completely fitted, the engaging claw rides on the convex portion and the plate portion is displaced in a direction away from the convex portion. To do. This displacement is caused by the slide member. If the plate portion is pressed, the second housing can be pressed to the first housing side along the punching direction, and the first housing and the second housing can be completely fitted. It becomes possible.

In the present invention, the concept of “electric wire” includes FFC (Flexible Flat Cable), FPC (Flexible Print Cable) and the like.

[0008] By the way, the slide member is provided so as to be positioned in the same plane as the pressing surface when the second housing is fitted to the first housing or inward of the second housing from the pressing surface. It ’s good to be! / By providing the slide member so that it does not protrude from the second housing! /, When the pressing surface of the second housing is pressed to fit the second housing and the first housing, Can prevent accidental pressing of the slide member.

[0009] Note that the slide member preferably includes an engaging portion that engages with the first housing. By engaging the slide member itself with the first housing, the slide member does not simply press the second housing to securely fit the first housing and the second housing. The function of restricting the fitting state of the second housing to the housing can be exhibited.

[0010] Further, a convex portion is formed in the first housing, and a first plate portion having an engaging claw that engages with the convex portion is formed in the second housing, and the engaging portion is slid. It can form in the 2nd plate part provided in the member. In this configuration, the engaging claw is engaged with the convex portion, and the first plate portion and the second plate portion are arranged to overlap each other with the engaging portion engaged with the first housing. Is preferred. When the second plate portion is pressed to release the engagement of the engagement portion with the first housing, the first plate portion is also pressed through the second plate portion, and the slide member, the first housing, And the engagement between the second housing and the first housing can be released simultaneously. Thereby, the fitting state of the slide member and the second housing to the first housing can be released by one operation.

[0011] In addition, protrusions are formed on both sides of the second plate portion of the slide member, and the second plate portion is provided on the second housing for releasing the engagement of the engagement portion with the first housing. Pressing A protrusion into which the protrusion enters, and when the protrusion enters into the recess, an overhanging portion is formed that is located on the side in which the second housing is pulled out from the first housing! /, It can also be characterized. When the second plate portion is pressed to release the engagement of the engagement portion with the first housing, the projection of the slide member enters the recess of the second housing. In this state, an overhang portion formed on the second housing is located on the side of the protrusion in the direction in which the first housing force is also pulled out. Therefore, when the second housing is pulled out from the first housing, the protrusion hits the overhanging portion. By pressing the second plate portion to release the engagement of the engagement portion with the first housing, the first plate portion is also pressed via the second plate portion, and the slide member and the first housing are pressed. If the engagement with the housing and the engagement between the second housing and the first housing are released at the same time, the first housing force can be pulled out of the slide member and the second housing. The sliding member is disengaged from the first housing and the second housing is disengaged from the first housing! / ,! Since the protrusion interferes with the overhang portion formed in the second housing engaged with the housing, it is not possible to slide only the slide member. The invention's effect

[0012] According to the present invention, by providing the slide member, the first housing and the second housing can be fitted to the first housing by the slide member even when the fitting between the first housing and the second housing is incomplete. It can be pressed to the housing side. As a result, the first housing and the second housing can be completely fitted, and the first contact and the second contact can be reliably electrically connected.

Further, by engaging the engaging portion of the slide member with the first housing, it becomes possible to restrain the fitting of the second housing to the first housing by the slide member. A complete fitting state with the second housing can be reliably maintained. Brief Description of Drawings

[0026] In order to ensure that the plugnos / housings 31 and the receptacles / housings 21 are fitted together, the connector 10 further includes a slide member 60 as shown in FIG.

The slide member 60 has a structure in which a base portion 61, a pair of columnar guide portions 62, a support portion 63, and a plate portion (second plate portion) 64 are integrally formed! /, The

The guide part 62 is formed to extend downward from the base part 61 in a state where the guide part 62 is attached to the plug housing 31. The support portion 63 is formed to protrude from the base portion 61 to the side. The plate portion 64 is formed so as to extend vertically from the support portion 63, whereby the slide member 60 has a substantially H shape in a side sectional view.

In order to hold the slide member 60, the plug housing 31 is provided with guide posts 53 on both sides of the lock plate 52, as shown in FIG. 6 (b). A recess 54 for holding the pair of columnar guide portions 62 is formed from the guide post 53 and the support portion 52a of the lock plate 52. The pair of columnar guide portions 62 are slidably held by the recesses 54 along the direction in which the plug housing 31 is removed from the receptacle housing 21 (in other words, in the vertical direction). That is, as a result, as shown in FIGS. 8A and 8B, the slide member 60 is supported by the plug housing 31 so as to be slidable in the vertical direction. At this time, as shown in FIG. 8 (a), the downward movement of the slide member 60 is restricted by the base portion 61 coming into contact with the upper surface of the plug housing 31. Further, as shown in FIG. 8 (b), the upward movement of the slide member 60 is restricted by the protrusions 65 formed on both sides of the plate portion 64 hitting the guide posts 53 of the plug housing 31. The guide portion 62 of the slide member 60 is inserted into the hole 43 formed in the receptacle housing 21 shown in FIG. 2 with the plug housing 31 fitted to the receptacle housing 21.

Now, the plate portion 64 of the slide member 60 shown in FIG. 8 is elastically displaceable in a direction in which the lower end portion of the plate portion 64 is separated from or approaches the plug housing 31.

Both end portions 64a and 64a in the width direction of the plate portion 64 are formed to protrude downward from the central portion 64b. As shown in FIG. 7 (b), engagement claws (engagement portions) 66 are formed on the surfaces facing the plug housing 31 when the plug housing 31 is mounted on both ends 64a and 64a of the plate portion 64. Being! /

As shown in FIG. 2, protrusions 44 are formed on both sides of the groove 42 on the side of the receptacle housing 21 corresponding to the engaging claws 66. As shown in FIG. 5 (b), the protrusion 44 is in a state where the plug housing 31 is fitted into the receptacle housing 21 and the base portion 61 of the slide member 60 is in contact with the upper surface of the plug housing 31. Thus, the engagement claw 66 is engaged. In such a slide member 60, the engagement claw 66 of the slide member 60 and the projection 44 of the plug housing 31 engage with each other, so that the plug housing 31 and the receptacle housing 21 are engaged by the engagement of the projection 41 and the engagement claw 51. It has the function to restrain the fitting state.

As shown in FIG. 9 (a), when the plug housing 31 is fitted into the receptacle housing 21, the plug housing 31 is pushed in so that the engaging claw 51 and the protrusion 41 are engaged. In this state, as shown in FIG. 9B, the engaging claw 66 of the slide member 60 and the projection 44 of the receptacle housing 21 are not engaged, and the engaging claw 66 is caught by the projection 44. . As a result, the slide member 60 is lifted from the plug housing 31.

Thereafter, by pushing only the slide member 60, the engagement claw 66 of the slide member 60 and the projection 44 of the receptacle housing 21 are engaged with each other as shown in FIG. 5 (b), so that the plug housing 31 and the receptacle are engaged. The fitting state with the housing 21 is restrained.

At this time, as shown in FIG. 9 (b), when the engaging claw 66 is caught by the protrusion 44 of the receptacle housing 21 and the sliding member 60 is lifted from the plug housing 31, the sliding member 60 60a does not protrude above the upper surface (pressing surface) 31a of the plug housing 31.

In addition, as shown in FIG. 10 (a), the slide member 60 is in an incompletely engaged state between the plug housing 31 and the receptacle housing 21, that is, the engagement between the protrusion 41 and the engaging claw 51 is incomplete. When it is, it has a function to fully engage them.

Therefore, the central portion 64b of the plate portion 64 has a pressing portion 67 at a corner portion facing the plug housing 31 side at the lower end thereof. When the engaging claw 51 of the plug housing 31 is not engaged with the protrusion 41 of the receptacle groove and the winging 21 and is riding on the protrusion 41, the lock plate 52 of the plug housing 31 has the tip of the receptacle It is elastically displaced so that it protrudes to the side away from Uzing 21. When the slide member 60 is pushed down in this state, as shown in FIG. 10 (b), the pressing portion 67 comes into contact with the tip of the protruding lock plate 52, and the lock plate 52, that is, the plug housing 31. Can be pressed downward. As a result, when the engaging claw 51 of the plug housing 31 and the protrusion 41 of the receptacle housing 21 are not completely engaged, the slide member 60 pushes down the plug housing 31, and as shown in FIG. The force S can be obtained by completely engaging the housing 31 and the receptacle housing 21. In order to reliably exhibit such a function, the lock plate 52 is preferably provided with a protrusion 55 on the surface opposite to the engagement claw 51. As shown in FIG. 10 (b), when the pressing portion 67 of the slide member 60 hits the projection 55, the plug housing 31 is reliably pushed down by the slide member 60.

Incidentally, the downward movement of the slide member 60 is restricted when the base portion 61 hits the plug housing 31. At this time, the base portion 61 is preferably formed so that the base portion 61 contacts the plug housing 31 at the same time that the pressing portion 67 contacts the protrusion 55. Thus, when the slide member 60 is pushed down, the plug 67 and the base 31 can be pushed down by the pressing portion 67 and the base portion 61, and the plug and the housing 31 can be surely pressed and fitted to the receptacle knot 21. .

[0031] Now, to release the fitting state of the plug housing 31 and the receptacle housing 21 from the state where they are restrained by the slide member 60, as shown in FIGS. 11 (a) and 11 (b). , The upper end portion of the plate portion 64 of the slide member 60 is pressed against the plug housing 31 side. When the mating state of the plug housing 31 and the receptacle housing 21 is restrained by the slide member 60, the lock plate 52 of the plug housing 31 is positioned behind the plate portion 64, and the plate When the upper end portion of the portion 64 is pressed, the upper end portion of the lock plate 52 is simultaneously pressed.

If the plug housing 31 is pulled away from the receptacle housing 21 in this state, the plug housing 31 and the slide member 60 are removed from the receptacle housing 21, and the mating between the plug connector 30 and the receptacle connector 20 is released. Can do.

In this way, the slide member 60 and the plug nosing 31 can be pulled out by one operation of pressing the upper end portion of the plate portion 64 rather than pulling out each separately.

As described above, in the connector 10, in addition to the fitting of the plug housing 31 and the receptacle housing 21, the fitting of the plug housing 31 and the receptacle housing 21 is achieved by fitting the slide member 60 and the receptacle housing 21 together. Can be performed reliably. In addition, when the plug housing 31 and the receptacle housing 21 are not completely fitted, the plug member 31 can be pushed in by pushing the slide member 60 so that the plug housing 31 and the receptacle housing 21 are completely connected. It can be mated.

Further, the upper end portion 60 a of the slide member 60 does not protrude above the upper surface 31 a of the plug housing 31 when the engaging claw 66 is hooked on the protrusion 44 of the receptacle housing 21 and is lifted from the plug housing 31. Therefore, when the plug housing 31 is pushed in, the slide member 60 can be prevented from being pushed together with the plug housing 31, and the slide member 60 can be pushed in reliably.

In addition, when the slide member 60 and the plug housing 31 are pulled out from the receptacle housing 21, the engagement of the slide member 60 and the plug housing 31 with respect to the receptacle housing 21 is performed by one operation of pressing the upper end portion of the plate portion 64 of the slide member 60. Together Can be released. Accordingly, it is possible to easily remove the slide member 60 and the plug nosing 31.

It is necessary to perform an operation of pulling the plug housing 31 away from the receptacle housing 21 after performing the operation of pressing toward the 31 side. However, when a person who does not know the correct procedure tries to release the fitting between the plug connector 30 and the receptacle connector 20, the operation of pressing the upper end portion of the plate portion 64 of the slide member 60 toward the plug housing 31 side, The operation of pulling the plug housing 31 away from the receptacle housing 21 may be performed at the same time. Then, as shown in FIG. 12, the plug connector 30 is not pulled up, and only the slide member 60 is pulled up. As a result, the engaging claw 51 at the lower end of the lock plate 52 remains engaged with the protrusion 41, and the plug connector 30 cannot be pulled out from the receptacle connector 20. Therefore, only a person who is familiar with the correct removal procedure can remove the plug connector 30 from the receptacle connector 20, which may cause trouble.

Therefore, it is effective to adopt the following configuration.

As shown in FIGS. 13 and 14 (a), protrusions 70 are formed on both sides of the plate portion 64 of the slide member 60. FIG. On the other hand, as shown in FIGS. 13 and 14 (b), the plug connector 30 has an upper end portion of the plate portion 64 of the slide member 60 in order to release the fitting between the plug connector 30 and the receptacle connector 20. A concave portion 71 into which the projection 70 enters when the plate portion 64 is elastically displaced by pressing toward the plug housing 31 is formed. An overhanging portion 72 that protrudes toward the slide member 60 is formed above the recess 71. As shown in FIG. 15 (a), the overhanging portion 72 is configured such that the upper end portion of the plate portion 64 is pressed toward the plug housing 31 from the state in which the engaging claws 66 and the protrusions 44 are engaged, and the protrusion 70 becomes the recess 71. It is formed so as to be positioned above the projection 70 when it enters. Also, as shown in FIGS. 16 (a) and 16 (b), the overhanging portion 72 and the protrusion 70 do not interfere with each other when the slide member 60 is slid with respect to the plug housing 31! /.
