Hereinafter, one preferred embodiment of the present invention will be described with reference to the accompanying drawings. For convenience, only suitable embodiments are shown, but of course, this is not intended to limit the invention.

FIG. 1 shows a perspective view of an electric connector assembly 1 to which an unlocking mechanism as an example of the present invention is applied, FIG. 2 shows a side view thereof, and FIG. 3 shows a sectional view taken along line AA of FIG. ..

The electric connector assembly 1 is composed of a pair of a receptacle connector 20 and a plug connector 60. The receptacle connector 20 and the plug connector 60 each have a symmetrical shape. The receptacle connector 20 can be fixed to the substrate 2 and the plug connector 60 can be fixed to the substrate 6 for use. The receptacle connector 20 and the plug connector 60 can be fitted or removed by bringing the substrates 2 and the substrates 6 facing each other close to each other or separated from each other along the direction of the arrow “α” in the drawing. 1 to 3 show a state before fitting them. 4 and 5 show the state after fitting. FIG. 4 is a partially broken perspective view, and FIG. 5 is a cross-sectional view thereof.

As is well shown in FIGS. 3 and 5, the receptacle connector 20 is mainly composed of a housing 21 and a plurality of, in this case, five contacts 22 arranged in a row in the housing 21 along the “β” direction. Further, it has a lock piece 30 arranged at the end of the contact row along the arrangement direction "β" of these contacts 22.

The housing 21 has a substantially rectangular outer shape, and includes a base 23 having a predetermined thickness on which the contacts 22 are installed, and a side wall 27 erected around the base 23. The fitting side with the plug connector 60 is open, and an insertion space 21a into which a part of the plug connector 60 is inserted is provided inside the housing 21 in a state of communicating with the opening.

Each contact 22 is erected in the insertion space 21a of the housing 21 toward the fitting side with the plug connector 60 along the fitting / removing direction “α”. Each contact 22 may be formed as a pair of a long terminal portion 22A that is slightly longer in the fitting / removing direction “α” and a short terminal portion 22B that is slightly shorter in the same direction. The long terminal portion 22A and the short terminal portion 22B are inserted into the holes of the substrate 2 in a state of being combined with each other at their terminal 22c. The contact portion 22a with the mating contact in the long terminal portion 22A is arranged closer to the mating contact in the fitting removal direction "α" than the contact portion 22b with the mating contact in the short terminal portion 22B. As a result, when the receptacle connector 20 and the plug connector 60 are fitted, each contact 22 is connected at a timing different from that of the mating contact.

The lock piece 30 is formed as a metal plate-like body erected along the fitting / removing direction “α” toward the fitting side with the plug connector 60. The lock piece 30 is erected in the same direction toward the fitting side with the plug connector 60 by inserting and fixing the end portion into the hole provided in the substrate 2. The insertion-side tip of the lock piece 30 is supported by a support portion 27a projecting inward of the side wall 27 of the housing 21 in the arrangement direction "β" of the contact 22.

The lock portion 32 may be, for example, a locking hole provided on the tip end side of the lock piece 30, that is, on the fitting side with the plug connector 60. The locking hole 32 can be easily formed by punching out a metal plate. However, the lock portion is sufficient as long as it can form a lock with the corresponding lock portion on the other side, and does not necessarily have to be the locking hole 32. For example, instead of the locking hole 32, it may be a recess or the like, or it may be formed by a member other than the plate-shaped body.

The plug connector 60 is mainly composed of a housing 61, a plurality of contacts 62 arranged in a row in the housing 61 along the "β" direction, in this case, five contacts 62, and further, the arrangement direction "β" of these contacts 62. With a displacement member 70 arranged at the end of the contact row along the line.

The housing 61 has a substantially rectangular outer shape, and has a plate-shaped base 63 having a predetermined thickness on which the contact 62 is installed, and a fitting / removing direction from the base 63 toward the fitting side of the receptacle connector 20. A plurality of, here, four contact holding portions 65 suspended along "α" and one at each end of the contact holding portion row along the arrangement direction "β" of these contact holding portions 65 are provided. The guide portion 66 is provided.

The contact 62 is held in the outer wall of the contact holding portion 65 in a state of being embedded therein.

The guide portion 66 has a function of guiding the plug connector 60 to the insertion space 21a (see FIG. 3) on the receptacle connector 20 side when the receptacle connector 20 and the plug connector 60 are fitted. Tapers 66a and 66c are provided at the fitting side tip of the guide portion 66 so that the guidance can be performed smoothly. For the same reason, a taper 65a is also provided at the tip of the contact holding portion 65 on the fitting side.
A holding portion 65'corresponding to a part of the contact holding portion 65 is provided on the array side of the contact holding portion in the guide portion 66. A contact 62 is embedded in the holding portion 65's like the contact holding portion 65.
On the other hand, the outer wall 66d of the guide portion 66 on the side opposite to the arrangement side of the contact holding portion is provided with a recess 66b capable of accommodating the displacement member 70 in a state where the displacement member 70 is allowed to be displaced. The recess 66b is formed in the arrangement direction "β" of the contact 62 from the side 70a opposite to the arrangement side 70b of the contact 62 to the arrangement side 70b with respect to the displacement member 70. According to this configuration, the plug connector 60 can be miniaturized in the arrangement direction "β" of the contact 62 without impairing the function of the guide portion, and the electric connector assembly 1 can be miniaturized. .. Further, according to this configuration, since the accommodating side of the displacement member is protected by the contact holding portion 65, the strength of the displacement member can be increased. The displacement member 70 is preferably housed in the recess 66b over the entire length in the fitting / removing direction “α”. By protecting substantially the entire displacement member 70 with the housing 61, the displacement member 70 is excessively displaced even when an excessive force is applied to the displacement member 70 due to, for example, prying at the time of fitting. This can prevent damage and the like.

The contact 62 may have a substantially plate shape. The contact 62 is embedded in the wall of the contact holding portion 65 or the holding portion 65'of the guide portion 66, and is erected along the fitting / removing direction "α" toward the fitting side with the receptacle connector 20. It is provided in a state of being. Each contact 62 may be formed as a pair of terminals 62A and 62B. The pair of terminals 62A and 62B are embedded in the wall of the contact holding portion 65 or in the holding portion 65'of the guide portion 66 in a state of facing each other, and their ends 62a are combined with each other in the substrate 6. It is inserted into the hole. When the receptacle connector 20 and the plug connector 60 are fitted, the contact portion 22a of the long terminal portion 22A of the receptacle connector 20 comes into contact with the terminal 62A of the plug connector 60, and the contact portion 22b of the short terminal portion 22B of the receptacle connector 20 is formed. It contacts terminals 62B of the plug connector 60 and they are electrically connected.

The displacement member 70 is formed of a metal plate, and is erected along the fitting / removing direction “α” toward the fitting side with the receptacle connector 20. Since it is made of a metal plate, it has a predetermined elastic displacement action. Since the plate surface side of the displacement member 70 is separated from the wall forming the recess 66b of the guide portion 66 by a predetermined distance, the displacement action of the displacement member 70 is not hindered. The displacement member 70 is press-fitted and fixed to the recess 66b on both side surfaces by using the press-fitting portions 70c (see FIG. 2) provided on both side portions.

The displacement member 70 includes a corresponding lock portion provided corresponding to the lock portion 32 provided on the lock piece 30. The corresponding locking portion may be, for example, a locking protrusion 72 provided on the tip end side of the displacement member 70, that is, on the fitting side with the receptacle connector 2. However, it is not always necessary to provide it on the tip side, and it is not necessary to provide the locking protrusion 72. The corresponding lock portion is sufficient as long as it can form a lock with the lock portion 32 on the other side. When the receptacle connector 20 and the plug connector 60 are fitted, the locking protrusion 72 provided on the plug connector 60 is locked in the locking hole 32 provided on the receptacle connector 20, whereby the receptacle connector 20 and the plug connector 60 are fitted. If it is locked.

The displacement member 70 further includes an operated portion that can be operated from the outside of the connector by a jig or the like. The operated portion may be formed as, for example, a contact portion 71. The contact portion 71 may be provided in a state of protruding from the array side 70b of the contact 62 toward the side 70a opposite to the array side.

With reference to FIGS. 6 to 9, a contact portion 71 provided on the displacement member 70 and a movable portion, for example, a jig 7, are used to lock between the locking protrusion 72 and the locking hole 32. The cancellation method will be described.
6 is a partially broken perspective view corresponding to FIG. 4, FIG. 7 is a cross-sectional view corresponding to FIG. 3, and these views show a state before the jig 7 abuts on the contact portion 71. ing. On the other hand, FIG. 8 is a partially broken perspective view corresponding to FIG. 4, FIG. 9 is a cross-sectional view corresponding to FIG. 3, and these views are when the jig 7 is in contact with the contact portion 71. Indicates the state of.

The jig 7 is composed of a grip portion 7a and two insertion portions 7b extending in the same direction from the grip portion 7a, and has a substantially U-shape in front view. The jig 7 is made of metal in order to obtain strength.

The insertion portion 7b of the jig 7 faces the inside of the electric connector assembly 1 from the side of the plug connector 60 toward the side of the receptacle connector 20 through the hole 6a provided in the substrate 6, and more specifically, the substrate on the plug connector 60 side. It is inserted into the space 63a provided in 63 and the space 27c formed inside the side wall 27 of the housing 21 of the receptacle connector 20. Upon insertion, the jig 7 slides on its surface along the displacement member 70. By moving the jig 7 along the displacement member 70 in this way, the operation of the jig 7 can be stabilized. Since the displacement member 70 is made of metal, there is almost no possibility that the displacement member 70 will be scraped by the jig 7.

As shown in FIGS. 6 and 7, before the jig 7 abuts on the contact portion 71, the locking protrusion 72 is locked to the displacement member 70 on the side 70a opposite to the arrangement side 70b of the contact 62. A lock is formed between the hole 32 and the hole 32. The locking protrusion 72 is arranged on the fitting side of the contact portion 71 in the fitting / removing direction “α”, and the contact portion 71 has a locking hole 32 adjacent to the locking protrusion 72. It is arranged so as not to interfere with the locking with the locking protrusion 72.

As shown in FIGS. 8 and 9, when the jig 7 comes into contact with the contact portion 71 of the displacement member 70, the locking protrusion 72 of the displacement member 70 contacts the displacement member 70 through the contact. The 62 is displaced from the side 70a opposite to the arrangement side 70b toward the arrangement side 70b, that is, in the "β1" direction, and as a result, the locking protrusion 72 and the locking hole 32 are unlocked. Since the contact portion 71 is arranged adjacent to the locking protrusion 72, the contact portion 71 can efficiently transmit the force received from the jig 7 to the locking protrusion 72 at this time. As described above, according to this configuration, the locking protrusion 72 can be operated from the side of the plug connector 60 through the substrate 6 through the contact between the contact portion 71 and the jig 7, and with respect to the displacement member 70. The operation can be performed on the side 70a opposite to the arrangement side 70b of the contact 62, in other words, not between the contact row and the locking protrusion 72, but on the outside thereof. In this way, by operating the locking protrusion 72 by the jig 7 on the side opposite to the arrangement side of the contacts 62, there is no need for a space for interposing the jig 7 between the contact row and the locking protrusion 72. Therefore, the plug connector 60 can be miniaturized, and the electric connector assembly 1 can be miniaturized, particularly in the arrangement direction “β” of the contact 62.

The present invention is not limited to the above-described embodiment, and various other modifications can be made. For example, as shown in FIG. 10, the grip portion of the jig 7 is removed to leave only the insertion portion 7c, and instead, the end portion 7c'of the insertion portion 7c is exposed to the outside, and if necessary, the end portion is exposed. The insertion portion 7c may be operated through the 7c'. As a result, the lock can be released without using a dedicated jig. Further, although the operated portion has been described as a contact portion which is a protruding portion, it is sufficient that the operated portion can be displaced by operating a jig or the like which is a movable portion. It is not limited to the contact portion.
