Description

  The present invention relates to an electrical connector assembly for electrically connecting a printed wiring board and a cable, and more particularly to an electrical connector assembly for preventing incomplete mating of connectors.

When fitting a male member and a female member of an electrical connector (hereinafter simply referred to as a connector), it is necessary to reliably connect the male member contact and the female member contact electrically. Therefore, a protrusion is formed on one of the housing of the male member and the housing of the female member, and an engaging claw is formed on the other of the housing of the male member and the female member. A mechanism for maintaining the fitting state of the housing of the male member and the female member by engaging them is widely used (see, for example, Patent Document 1).
In the connector having such a mechanism, the operator pushes one housing into the other housing, and the male member and the female member are brought into contact with each other when the protrusion and the engaging claw are engaged. It can be recognized that the fitting can be surely performed.

In recent years, with the miniaturization of various devices including portable communication terminals, miniaturization of connectors is also required. As a result of the miniaturization of the connector, there has been a problem that the male member and the female member of the connector cannot be reliably connected at the site where manufacturing, repair, etc. are performed.
The fitting / separation work between the male member and the female member of the connector is performed by the operator's fingertip, but when the male member and the female member are smaller than the fingertip of the operator, the male member of the connector The work itself for fitting and separating the female member and the female member becomes difficult. Further, with the miniaturization of the connector, the protrusions and the engaging claws are also reduced, and it is conceivable that the touch when they are engaged becomes difficult to recognize by the fingertip of the operator.
If the fitting between the male member and the female member of the connector is uncertain, the electrical connection between the contacts will be obstructed. For this reason, even if it is a small connector, the mechanism which fits the male type member and female type member of a connector reliably, and can connect contacts reliably is requested | required.

  The present invention has been made based on such a technical problem, and provides an electrical connector assembly that can securely connect a male member and a female member of a connector so that contacts can be reliably connected. With the goal.

An electrical connector assembly of the present invention made for such an object is an electrical connector assembly for electrically connecting a printed wiring board and an electric wire, and a first housing fixed to the printed wiring board, 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 a first contact held in the second housing. And a second contact connected to the electric wire, and a slide member held on the second housing so as to be movable along the insertion / extraction direction of the second housing with respect to 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 to each other. The printed wiring board and the electric wire are electrically connected via the second contact.
In the electrical connector assembly having such a configuration, when the fitting between the first housing and the second housing is incomplete, by sliding the slide member toward the first housing along the insertion / extraction direction, The second housing can be pressed. 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 an engaging claw that engages with the convex portion is formed on the second housing. Since the first plate portion having the first housing portion is formed , when the first housing and the second housing are incompletely fitted, the first pawl portion protrudes from the convex portion by the engagement claw riding on the convex portion. Displacement in the direction of separation. If the displaced first plate portion is pressed by the slide member, the second housing can be pressed toward the first housing along the insertion / removal direction, and the first housing and the second housing are connected to each other. It becomes possible to make it fit completely.
In the present invention, the concept of “electric wire” includes FFC (Flexible Flat Cable), FPC (Flexible Print Cable) and the like.

  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. Is preferred. By providing the slide member so as not to protrude from the second housing, when the pressing surface of the second housing is pressed to fit the second housing and the first housing, the slide member is held by a finger. You can prevent accidental pressing.

The slide member includes an engaging portion that engages with the first housing . By engaging the slide member itself with the first housing, the slide member not only presses the second housing to securely fit the first housing and the second housing but also the first housing. The function of restraining the fitting state of the second housing to the housing can be exhibited.

In addition, a convex portion is formed on the first housing, and a first plate portion having an engaging claw that engages with the convex portion is formed on the second housing, and the engaging portion is provided on the slide member. Formed on the formed second plate portion . In this configuration, the engaging claw is engaged with the convex portion, and the first plate portion and the second plate portion are arranged so as to overlap each other with the engaging portion engaged with the first housing. . When the second plate portion is pressed to release the engagement of the engaging portion from the first housing, the first plate portion is also pressed via the second plate portion, and the slide member, the first housing, And the engagement between the second housing and the first housing are simultaneously released. Thereby, it is possible to release the fitting state of the slide member and the second housing to the first housing by one operation.

  In addition, protrusions are formed on both sides of the second plate portion of the slide member, and when the second plate portion is pressed against the second housing to release the engagement of the engagement portion with the first housing. The projection is formed with a recess, and when the projection enters the recess, an overhang is formed on the projection that is located on the side in which the second housing is pulled out from the first housing. You can also. 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 second housing is pulled out from the first housing. Therefore, when the second housing is pulled out from the first housing, the protrusion hits the overhanging portion. By pressing the second plate part to release the engagement of the engaging part with the first housing, the first plate part is also pressed through the second plate part, and the slide member and the first housing And the second housing and the first housing are simultaneously released, the slide member and the second housing can be pulled out from the first housing. When the engagement between the slide member and the first housing is released and the engagement between the second housing and the first housing is not released, the slide member is engaged with the first housing engaged with the first housing. Since the protrusion interferes with the overhang portion formed in the second housing, it is not possible to slide only the slide member.

According to the present invention, by providing the slide member, the second housing is pressed against the first housing by the slide member even when the fitting between the first housing and the second housing is incomplete. can do. 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, and the first housing and the first housing A complete fitting state with the second housing can be reliably maintained.

As shown in FIG. 3, the plug connector 30 includes a resin plug housing (second housing) 31 fitted into the receptacle housing 21 and a contact (second contact) 32 made of a conductive material such as a copper alloy. It consists of and.
On the lower surface side of the plug housing 31, a convex portion 33 that fits into the concave portion 23 of the receptacle housing 21 is formed. A plurality of contacts 32 are held in the plug housing 31 so as to correspond to the plurality of contacts 22 of the receptacle connector 20 while being spaced apart from each other. In each contact 32, the contact portions 32 a and 32 b are exposed from the opening formed on the side surface of the convex portion 33.

  Here, the contact 32 may have any configuration as long as it can be electrically connected to the contact 22, but in the present embodiment, as shown in FIG. 1, the electric wire 100 connected to the contact 32. However, the contact 32 of the structure arrange | positioned so that it may extend in the direction orthogonal to the insertion / extraction direction of the plug housing 31 with respect to the receptacle housing 21 is mentioned as an example.

As shown in FIG. 4, the contact 32 has a barrel portion 34 that is crimped to the electric wire 100, and a plate portion 35 that is continuous with the barrel portion 34 and is formed to extend downward perpendicular to the barrel portion 34. However, the shape is substantially L-shaped. The barrel portion 34 includes a wire barrel 34 a that is crimped to the core wire of the electric wire 100, and an insulation barrel 34 b that is crimped to the sheath of the electric wire 100. The contact portions 32 a and 32 b are bent at a lower portion of the plate portion 35 so as to be orthogonal to the plate portion 35.
As shown in FIGS. 1 and 3, such a contact 32 is accommodated in a cavity 36 formed in the plug housing 31, and the contact portions 32 a and 32 b are formed on the protrusion 33 of the plug housing 31 as described above. It is exposed and held from the opening formed in the side surface. Here, as shown in FIG. 1, the contact 32 may be held by the plug housing 31 by using a lance 32 c formed on the contact 32 and engaging the contact 32 with the plug housing 31. Alternatively, a technique such as molding may be used.

  As shown in FIG. 5, such a plug connector 30 is fitted into the receptacle connector 20 by inserting the convex portion 33 of the plug housing 31 into the concave portion 23 of the receptacle housing 21. Then, the contact portions 32 a and 32 b of the contact 32 on the plug connector 30 side are electrically connected to the contact beams 22 a and 22 b of the contact 22 positioned in the recess 23 of the receptacle housing 21.

In order to maintain the fitting state between the plug housing 31 and the receptacle housing 21, a protrusion (convex portion) 41 is formed on the side surface of the receptacle housing 21, and the engagement claw that engages with the protrusion 41 is formed on the plug housing 31. 51 is formed.
As shown in FIG. 2, the protrusion 41 is provided in a groove 42 formed in the side surface of the receptacle housing 21 and continuing in the vertical direction.
On the other hand, as shown in FIG. 6A, the engaging claw 51 is formed at a lower end portion of a lock plate (plate portion, first plate portion) 52 provided on the side portion of the plug housing 31. The lock plate 52 is formed along the groove 42 in a state in which the plug housing 31 is fitted to the receptacle housing 21. The lock plate 52 is integrally formed with the plug housing 31 by a support portion 52a having an L-shaped cross section formed so as to protrude laterally from the plug housing 31. The lock plate 52 is formed with notches 52c and 52c in the vicinity of the support portion 52a, whereby the lock plate 52 can be elastically displaced in a direction in which the tip end side is separated from or approaches the plug housing 31. . As shown in FIG. 5A, the engagement claw 51 is opposed to the protrusion 41 on the side surface of the receptacle housing 21 with the plug housing 31 fitted to the receptacle housing 21 at the lower end portion of the lock plate 52. It is formed to do. The engagement state between the plug housing 31 and the receptacle housing 21 is maintained by the engagement of the engagement claws 51 and the protrusions 41.

In order to securely engage the plug housing 31 and the receptacle housing 21, the connector 10 further includes a slide member 60 as shown in FIG.
The slide member 60 has a configuration 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 guide portion 62 is formed to extend downward from the base portion 61 in a state where the guide portion 62 is attached to the plug housing 31. The support part 63 is formed to protrude from the base part 61 to the side. The plate portion 64 is formed 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, guide posts 53 are provided on both sides of the lock plate 52 in the plug housing 31 as shown in FIG. A concave portion 54 for holding a pair of columnar guide portions 62 is formed from the guide post 53 and the support portion 52 a of the lock plate 52. The pair of columnar guide portions 62 are slidably held by the concave portions 54 along the insertion / extraction direction of the plug housing 31 with respect to 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. 8A, the downward movement of the slide member 60 is restricted by the base portion 61 hitting the upper surface of the plug housing 31. Further, as shown in FIG. 8B, 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 can be elastically displaced 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 so as to protrude downward from the central portion 64b. As shown in FIG. 7 (b), engaging claws (engaging portions) 66 are formed on both ends 64 a, 64 a of the plate portion 64 on the surface facing the plug housing 31 when mounted on the plug housing 31. Has been.
As shown in FIG. 2, projections 44 are formed on both sides of the groove 42 on the receptacle housing 21 side corresponding to the engaging claws 66. As shown in FIG. 5 (b), the protrusion 44 is engaged when the plug housing 31 is fitted in 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. Engage with the pawl 66.
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, whereby 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. 9A, when the plug housing 31 is fitted into the receptacle housing 21, the plug housing 31 is pushed in so that the engagement 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 protrusion 44 of the receptacle housing 21 are not engaged, and the engaging claw 66 is caught by the protrusion 44. As a result, the slide member 60 is lifted from the plug housing 31.
Thereafter, by pushing only the slide member 60, as shown in FIG. 5B, the engagement claw 66 of the slide member 60 and the protrusion 44 of the receptacle housing 21 are engaged, and 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. 9B, when the engaging claw 66 is hooked on the projection 44 of the receptacle housing 21 and the slide member 60 is lifted from the plug housing 31, the slide member 60 has its upper end portion. 60 a does not protrude above the upper surface (pressing surface) 31 a of the plug housing 31. If the upper end portion 60a of the slide member 60 protrudes above the upper surface 31a of the plug housing 31 in this state, the slide member 60 may be pushed together with the plug housing 31 when the plug housing 31 is pushed. Because there is.

Further, as shown in FIG. 10A, the slide member 60 is in a fitted state between the plug housing 31 and the receptacle housing 21, that is, when the engagement between the projection 41 and the engagement claw 51 is incomplete. , And has a function for completely engaging them.
For this reason, the central portion 64b of the plate portion 64 has a corner portion facing the plug housing 31 at the lower end portion as a pressing portion 67. When the engagement claw 51 of the plug housing 31 does not engage with the protrusion 41 of the receptacle housing 21 and rides on the protrusion 41, the lock plate 52 of the plug housing 31 is separated from the receptacle housing 21 at the tip. It is elastically displaced so that it protrudes to the side. When the slide member 60 is pushed down in this state, as shown in FIG. 10B, the pressing portion 67 comes into contact with the protruding tip of the lock plate 52, and the lock plate 52, that is, the plug housing 31 is moved downward. Can be pressed. As a result, when the engagement 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. 31 and the receptacle housing 21 can be completely engaged. 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. 10B, when the pressing portion 67 of the slide member 60 hits the protrusion 55, the plug housing 31 is surely pushed down by the slide member 60.
Incidentally, the downward movement of the slide member 60 is restricted by the base portion 61 hitting 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 as the pressing portion 67 contacts the protrusion 55. Thereby, when the slide member 60 is pushed down, the plug housing 31 can be pushed down by the pressing portion 67 and the base portion 61, and the plug housing 31 can be surely pressed and fitted into the receptacle housing 21.

In order to release the fitting state between the plug housing 31 and the receptacle housing 21 from the state in which the plug member 31 and the receptacle housing 21 are restrained by the slide member 60, as shown in FIGS. 11A and 11B, the slide member 60 is used. The upper end portion of the plate portion 64 is pressed toward the plug housing 31 side. In a state where the fitting state of the plug housing 31 and the receptacle housing 21 is constrained by the slide member 60, the lock plate 52 of the plug housing 31 is positioned behind the plate portion 64. When the upper end portion of the lock plate 52 is pressed, the upper end portion of the lock plate 52 is simultaneously pressed. Then, the lower end portion of the plate portion 64 and the lower end portion of the lock plate 52 are elastically displaced in a direction away from the receptacle housing 21, and the engagement between the engagement claw 51 and the projection 41 and the engagement between the engagement claw 66 and the projection 44 are performed. Is released. In this state, if the plug housing 31 is pulled out in a direction away from the receptacle housing 21, the plug housing 31 and the slide member 60 can be removed from the receptacle housing 21, and the fitting between the plug connector 30 and the receptacle connector 20 can be released. it can.
In this way, the slide member 60 and the plug housing 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 between the plug housing 31 and the receptacle housing 21, the sliding member 60 and the receptacle housing 21 are fitted to each other so that the plug housing 31 and the receptacle housing 21 are fitted. Can be performed reliably. Further, when the fitting between the plug housing 31 and the receptacle housing 21 is incomplete, the plug housing 31 can be pushed in by pushing the slide member 60, and the plug housing 31 and the receptacle housing 21 are completely fitted. It becomes possible to make it.
Further, the upper end portion 60 a of the slide member 60 does not protrude upward from the upper surface 31 a of the plug housing 31 when the engaging claw 66 is caught by the protrusion 44 of the receptacle housing 21 and lifted from the plug housing 31. Therefore, it is possible to prevent the slide member 60 from being pushed together with the plug housing 31 when the plug housing 31 is pushed in, and the push-in operation of the slide member 60 can be reliably performed.
In addition, when the slide member 60 and the plug housing 31 are pulled out from the receptacle housing 21, the slide member 60 and the plug housing 31 are engaged with the receptacle housing 21 by one operation of pressing the upper end portion of the plate portion 64 of the slide member 60. Can be canceled. Therefore, the slide member 60 and the plug housing 31 can be easily removed.

  Here, as shown in FIGS. 11A and 11B, when the fitting between the plug connector 30 and the receptacle connector 20 is released, the upper end portion of the plate portion 64 of the slide member 60 faces the plug housing 31 side. After performing the pressing operation, the plug housing 31 needs to be pulled out in a direction away from the receptacle housing 21. 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, and the plug housing The operation of pulling 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 those who are 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 14A, projections 70 are formed on both sides of the plate portion 64 of the slide member 60. On the other hand, as shown in FIGS. 13 and 14B, the plug connector 30 has an upper end portion of the plate portion 64 of the slide member 60 connected to the plug housing 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 31 side is formed. A protruding 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 where the engaging claw 66 and the protrusion 44 are engaged, and the protrusion 70 becomes the recess 71. It is formed so as to be positioned above the protrusion 70 when it enters. Also, as shown in FIGS. 16A and 16B, the overhanging portion 72 and the protrusion 70 are formed at positions that do not interfere with each other when the slide member 60 is slid with respect to the plug housing 31.

When the fitting between the plug connector 30 and the receptacle connector 20 is released, as in the case shown in FIG. 11, after the operation of pressing the upper end portion of the plate portion 64 of the slide member 60 toward the plug housing 31 is performed, the plug An operation of pulling the housing 31 away from the receptacle housing 21 is performed. As shown in FIG. 15A, when an operation of pressing the upper end portion of the plate portion 64 of the slide member 60 toward the plug housing 31 is performed, the protrusion 70 enters the recess 71. In this state, when the operation of pulling the plug housing 31 away from the receptacle housing 21 is performed, the plug housing 31 and the slide member 60 are removed from the receptacle housing 21, and the fitting between the plug connector 30 and the receptacle connector 20 is released. Is done.
If the operator simultaneously performs the operation of pressing the upper end portion of the plate portion 64 of the slide member 60 toward the plug housing 31 and the operation of pulling the plug housing 31 away from the receptacle housing 21, the recess 71 The protrusion 70 that has entered contacts the overhanging portion 72. If the engagement claw 51 at the lower end of the lock plate 52 remains engaged with the protrusion 41, the plug connector 30 cannot be pulled upward from the receptacle connector 20, and therefore the slide member 60 is also moved upward. I can't. The operation of pressing the upper end portion of the plate portion 64 of the slide member 60 toward the plug housing 31 is reliably performed, and the engagement between the engagement claw 51 and the projection 41 and the engagement between the engagement claw 66 and the projection 44 are not released. As long as the slide member 60 does not move upward. In addition, by engaging the upper end of the plate portion 64 of the slide member 60 toward the plug housing 31, the engagement between the engagement claw 51 and the projection 41 and the engagement between the engagement claw 66 and the projection 44 are released. After that, when the plug housing 31 is pulled out in a direction away from the receptacle housing 21, the protrusion 70 that has entered the recess 71 hits the protruding portion 72, so that the slide member 60 and the plug connector 30 are pulled out integrally. Can do. That is, an operation of pressing the upper end portion of the plate portion 64 of the slide member 60 toward the plug housing 31 is performed, and the engagement between the engagement claw 51 and the projection 41 and the engagement between the engagement claw 66 and the projection 44 are released. It is possible to pull out the slide member 60 and the plug connector 30 as long as it is performed, and these operations can be performed continuously or in parallel.

Further, for example, when the plug housing 31 is fitted into the receptacle housing 21, the engagement claw 66 of the slide member 60 and the projection 44 of the receptacle housing 21 do not engage as shown in FIG. 9B. The plug housing 31 may be pulled out from the receptacle housing 21 without pushing the slide member 60 from the state where the engaging claw 66 is caught by the protrusion 44. In this case, as shown in FIG. 15B, the upper end portion of the plate portion 64 of the slide member 60 is pressed toward the plug housing 31. Then, the upper end portion of the lock plate 52 located behind the plate portion 64 is pressed by the plate portion 64, and the lower end portion of the lock plate 52 is elastically displaced in a direction away from the receptacle housing 21. The engagement with the protrusion 41 can be released. In this state, when the plug housing 31 is pulled out in a direction away from the receptacle housing 21, the fitting between the plug connector 30 and the receptacle connector 20 can be released.
As described above, the engagement claw 66 of the slide member 60 and the projection 44 of the receptacle housing 21 do not engage with each other, and the engagement claw 66 is caught by the projection 44 and the slide member 60 is lifted. In order to press the upper end portion, it is necessary to form the protrusion 70 and the projecting portion 72 in a positional relationship that does not interfere with each other so that the upper end portion of the plate portion 64 of the slide member 60 can be pressed toward the plug housing 31.

  In the above embodiment, the upper end portion 60 a of the slide member 60 does not protrude above the plug housing 31 so that the slide member 60 is not accidentally pressed simultaneously when the plug housing 31 is pushed into the receptacle housing 21. It was. For the same purpose, as shown in FIG. 17, it is also effective to extend the plug housing 31 to the side away from the slide member 60 so that the plug housing 31 can be pushed in at a position where the finger does not touch the slide member 60. It is. If the configuration shown in FIG. 17 can prevent erroneous finger contact, the upper end portion 60a of the slide member 60 projects upward from the upper surface 31a of the plug housing 31 while sliding upward. A configuration is also possible. With this configuration, the height of the plug housing 31 can be reduced.

Moreover, in the said embodiment, although the contact 32 of the plug connector 30 was set as the substantially L-shaped structure in which the electric wire 100 is located orthogonally to the insertion / extraction direction of the contact 32, it is not restricted to such a structure. As shown in FIG. 18, the plug connector 30 may be a type in which the electric wire 100 extends in the insertion / extraction direction of the contact 32. Even in this case, it is possible to obtain the same effect as described above by adopting the configuration as in the above embodiment and including the slide member 60.
Furthermore, the contact shape and method of the contact 22 of the receptacle connector 20 and the contact 32 of the plug connector 30 are not limited to those described above, and may be contacts of any other shape and method.

In addition, the receptacle housing 21 is a female housing having a recess 23, and the plug housing 31 is a male housing having a projection 33. However, the present invention is not limited to this, and the male housing and the female housing are replaced. Is also possible. Similarly, the contact 22 of the receptacle connector 20 is a female contact, and the contact 32 of the plug connector 30 is a male contact, but it is also possible to adopt a configuration in which the male contact and the female contact are interchanged. In that case, the receptacle connector 20 and the plug connector 30 may be configured to combine a female housing and a male contact, or a male housing and a female contact.
In addition to this, as long as it does not depart from the gist of the present invention, the configuration described in the above embodiment can be selected or changed to another configuration as appropriate.
