Japanese Patent Publication No. 2015-170500

In the electrical connector assembly of Patent Document 1, when an unexpected force in the connector ejection direction (upward) acts on a plug connector that is in a state of being fitted and connected to a receptacle connector, the lock bracket is a fatigue. The lock portion receives the upward force (output) from the fatigue portion of the bracket. This output power also acts on the base part and the standing part integral with the lock part. It is easy to deform to be bent upward by receiving the output, and the base, standing portion and lock portion are formed integrally with one plate portion having a flat plate surface, and in particular, the base portion is formed in the longitudinal direction of the housing. Since it has a long elongated shape, when the output power is large, there is a fear that the base is greatly bent upward and damaged.

In view of such circumstances, the present invention has an object to provide an electrical connector and an electrical connector assembly capable of reliably preventing deformation and breakage of the lock bracket even when an output is applied to the lock section of the lock bracket.

According to the present invention, the above-mentioned problems are solved by the electrical connector according to the first invention and the electrical connector assembly according to the second invention.

<First invention>

The electrical connector according to the first aspect of the invention is an electrical connector that is releasably fit-connected to a mating connector, the electrical connector comprising: a housing extending in a longitudinal direction in a direction perpendicular to the connector fitting direction; It has a terminal arranged in the housing in the direction of the terminal arrangement direction, a lock member held in the housing, and an elastic deformation portion, and the housing has a receiving portion for accepting a mating connector.

In such an electrical connector, in the first invention, the locking member is a connector fitting direction starting from a base portion having a portion extending in the terminal arrangement direction and a portion of the base within the range of the housing in the terminal arrangement direction. And a locking protrusion that protrudes toward the one end side of the housing from the standing portion in the terminal arrangement direction, and locks the release portion of the fatigue portion when it is fixed to the fatigue portion provided in the mating connector. In the connector width direction perpendicular to both directions of the connector fitting direction and the terminal arrangement direction, standing in the direction of the connector fitting direction from the base at a position adjacent to the lock protrusion, and including the lock protrusion in the terminal arrangement direction. It has a reinforcing part extending over a range, the locking member is arranged in the housing receiving portion, and the locking protrusion protrudes into the receiving portion, so that the locking position for fixing to the fatigue portion of the mating connector and the terminal arrangement direction It is movable to the other end side of the housing and can be moved between unlocking positions that become unlockable, and the elastic deformation portion is characterized in that the locking member is elastically supported toward the locking position.

As described above, in the first invention, the lock member stands up from the base to the connector fitting direction in a position adjacent to the lock protrusion in the connector width direction, and extends over the range including the lock protrusion in the terminal arrangement direction. It has a reinforcement part. Therefore, in the range where the reinforcing portion is provided in the terminal arrangement direction, the size of the locking member in the connector fitting direction is increased by the amount of the reinforcing portion as compared to the case where only the base is present as in the prior art. As a result, since the strength against bending deformation in the connector fitting direction is improved, the lock member can be countered without bending deformation even when receiving a large output from the mating connector.

In the first aspect of the invention, the lock member is made of a metal plate, and in a state bent in the plate thickness direction of the metal plate, a plurality of plate portions are overlapped in the connector width direction, and the lock protrusion is a part of the plurality of plate portions It is formed in the plate part of, and the reinforcement part may be formed in another plate part adjacent to some of the plate parts among the plurality of plate parts. By making the lock member such a structure, the lock member can be easily manufactured from one sheet of metal plate member.

In the first invention, the lock member is a solid member in which materials are continuous in any of the connector fitting direction, the terminal arrangement direction, and the connector width direction, and the lock protrusion is a connector width direction of the lock member It may be formed in a part of the entire range of, and the reinforcement portion may be formed in the remainder of the entire range in the connector width direction of the lock member.

When the lock member is configured as such, since the lock protrusion and the reinforcement part are directly connected and integrated in the thickness direction, the lock protrusion is strongly reinforced. In addition, since the lock bracket is formed integrally with a thickness dimension that extends across the connector width direction except for the lock protrusion and the reinforcement, the strength of each part itself is also improved. Therefore, since greater strength is obtained over the entire lock bracket, it is possible to sufficiently counteract unexpected connector output.

In the first aspect of the invention, when the lock protrusion of the lock member is in the locked position in the connector fitting state, it is elastically supported by the elastic deformation portion, and the protruding tip may be in contact with the member having the fatigue portion of the mating connector. By setting it as such a structure, the member which has the said fatigue part is pressed by the said lock protrusion part in the terminal arrangement direction, and movement of the plug connector in the same direction is restricted. Therefore, it is possible to prevent the occurrence of an abnormal sound caused by the connectors having relatively reciprocating motions in the terminal arrangement direction and the members having the lock protrusions and the fatigue parts colliding with each other, and further, the lock protrusions and the fatigue It is possible to prevent damage to the member having the wealth.

In the first invention, the electrical connector has a shield member attached to the housing, and the elastic deformable portion may be integrally formed with the shield member. By forming the elastically deformable portion integrally with the shield member in this way, compared with the case where the elastically deformable member is provided as a separate member from the shield member, the number of parts can be reduced, and manufacturing cost can be suppressed. . In addition, when the connector is manufactured, the elastically deformable portion is also simultaneously attached by the attachment of the shield member to the housing, so that the step of attaching the elastically deformable member to the housing can be omitted, thereby simplifying the manufacture of the connector.

<Second invention>

The electrical connector assembly according to the second invention includes the electrical connector according to the first invention and a mating connector that is matedly connected to the electrical connector, wherein the mating connector is a locking member of the electric connector in the connector fitting state It characterized in that it has a fatigue portion that can be fixed to the locking projection in the direction of blocking the ejection of the connector.

In the present invention, as described above, by providing the reinforcing portion at a position adjacent to the locking protrusion of the locking member, the lock bracket has dimensions of the locking member in the connector fitting direction in a range where the reinforcing portion is provided in the terminal arrangement direction Compared to the conventional one, the size of the reinforcing portion is increased, and the strength against bending deformation in the connector fitting direction is improved, whereby the output from the mating connector can be sufficiently met.

Therefore, in this embodiment, the inner fatigue portion 72C of the fatigue bracket 70 positioned in front and the outer fatigue portion 75C of the fatigue bracket 70 positioned in the rear are not used. In addition, as described above, the lock bracket 30 can be installed in a position in which the posture shown in FIG. 4 is inverted left and right, and in this case, an inner fatigue portion of the fatigue bracket 70 located in the front. The outer fatigue portion 75C of the fatigue bracket 70 located at 72C and the rear side is used as the fatigue portion.

Next, the connector fitting operation of the receptacle connector 1 and the plug connector 2 is demonstrated based on FIGS. 1, 4, 6, and 7A. First, the receptacle connector 1 and the plug connector 2 are respectively attached to the corresponding circuit boards by solder connection. Next, as shown in FIG. 1, while the receptacle connector 1 is in an upwardly facing position, the receptacle connector 1 is in the upward direction, and the receptacle connector 1 is in an accepting portion of the plug connector 2. (56) (refer FIG. 2) is the downward facing position.

Next, the plug connector 2 is lowered while maintaining the posture of FIG. 1, and the protruding wall 12 of the receptacle connector 1 is introduced into the receiving portion 56 of the plug connector 2 from below. , The circumferential wall 53 of the plug connector 2 is introduced into the receiving portion 16 of the receptacle connector 1 from above. As a result, the contact leg portion 62A of the plug terminal 60 of the plug connector 2 is the contact portion 22A of the receptacle terminal 20 of the receptacle connector 1 or the inner contact piece of the shield member 40 ( 48) with contact pressure. In addition, as shown in Figs. 6A and 6B, the side plate portions 76 of the fatigue bracket 70 of the plug connector 2, respectively, are shield members of the corresponding receptacle connector 1 The outer contact piece 47 of 40 is brought into contact with the contact pressure.

In addition, in the connector fitting process, the lock protrusions 35A- of the lock brackets 30 in which the fatigue parts 75C and 72C of the two fatigue brackets 70 provided in the plug connector 2 are respectively in the lock position are provided. 1, 35B-1) in contact with the upper edge (inclined edge), and press the lock portions 35A, 35B with a pressing force toward the front (right side in Fig. 4) in the terminal arrangement direction. The lock portions 35A and 35B move forward when receiving the pressing force, and are respectively accommodated in the front end wall groove portion 17B and the rear projecting wall groove portion 17F (see FIG. 7(B)). Is brought into. At this time, the movement of the lock portions 35A and 35B is allowed by elastic deformation (compression) of the elastic deformation portion 45 pressed by the abutting portion 36B-1 of the lock bracket 30.

As described above, further dropping of the plug connector 2 is permitted by bringing the lock portions 35A, 35B to the unlocked position. And, as shown in Fig. 7(A), the fatigue of the outer fatigue portion 75C and the rear (left in Fig. 7(A)) of the fatigue bracket 70 in the front (right in Fig. 7(A)) When the inner fatigue portion 72C of the large bracket 70 reaches a position lower than the lock protrusions 35A-1, 35B-1 of the lock bracket 30, the lock portions 35A, 35B are pushed as described above. Power. As a result, the elastic deformation portion 45 is restored to the rear so as to reduce the amount of elastic deformation, and returns to the original locked position. The lock protrusions 35A-1 and 35B-1 returned to the locked position are positioned above the corresponding fatigue parts 75C and 72C, respectively, as shown in Fig. 7A, and the fatigue parts 75C, With respect to 72C), the connector is placed in a lockable state in the direction in which the connector is ejected (above). At this time, the protruding tip of the front lock protrusion 35A-1 is in contact with the plate surface of the outer reinforcement portion 74B of the fatigue bracket 70 installed in the front, and the protruding tip of the rear lock protrusion 35B-1 is It is in contact with the plate surface of the inner reinforcement portion 73B of the fatigue bracket 70 installed at the rear.

In addition, the front sub-reinforcing portion 38A of the lock bracket 30 and the main reinforcing portion 37 in a range corresponding to the front sub-reinforcing portion 38A accommodate the reception of the fatigue bracket 70 positioned correspondingly in front. The groove portion 79 enters from below. On the other hand, the rear sub-reinforcing portion 38B of the lock fitting 30 and the main reinforcing portion 37 in a range corresponding to the rear sub-reinforcing portion 38B accommodate the reception of the fatigue fitting 70 located in the corresponding position. The groove portion 79 enters from below. As a result, the reinforcing portions 37, 38A, and 38B of the lock bracket 30 enter the short groove portion 55A of the end wall 55 of the plug connector 2.

In this way, the terminals 20 and 60 are connected to each other, the outer contact piece 47 and the side plate portion 76 are connected to each other, and the lock fittings 30 and 70 are locked to complete the connector fitting operation. do. In the connector fitting state, even if the plug connector 2 is unintentionally lifted in the connector ejection direction (upward), the respective phase edges of the standing portions 32A, 32C and the regulated portion 34A are receptacle-side housings 10 ), the movement of the lock bracket 30 toward the upper side is restricted because it comes into contact with the regulatory surfaces 17B-1, 17C-1, and 17E-2. As a result, the locked and locked states of the lock parts 35A and 35B of the lock bracket 30 and the fatigue parts 75C and 72C of the fatigue bracket 70 are maintained, so that a stable lock state can be maintained.

In this embodiment, as described above, in the lock bracket 30 of the receptacle connector 1, the inner plate portion 30B is provided, and the inner plate portion 30B includes not only the inner portion 31B, but also the inner portion 31B. , By providing the main reinforcing portions 37 and the sub-reinforcing portions 38A, 38B in the range including the lock portions 35A, 35B in the terminal arrangement direction, the height dimension of the inner plate portion 30B is largely secured. Therefore, since the sufficient strength is secured to the bending deformation of the locking bracket 30 as a whole, especially the bending deformation in the connector insertion direction, the locking bracket 30 is plugged in the connector fitting state. Even if an unexpectedly large output is received from the fatigue bracket 70 of the connector 2, the lock bracket 30 can resist the output without bending deformation.

In addition, in the present embodiment, as described above, in the fatigue bracket 70 of the plug connector 2, reinforcement plate portions 73 and 74 are provided to include the fatigue portions 72C and 75C. The fatigue parts 72C and 75C are reinforced by the reinforcing parts 73B and 74B located at. Therefore, even if the fatigue parts 72C and 75C receive an unexpectedly large output from the lock bracket 30 of the receptacle connector 1, it is possible to counter with sufficient strength.

Further, in the present embodiment, the main reinforcing portion 37 and the sub-reinforcing portions 38A and 38B of the lock fitting 30 of the receptacle connector 1 are the receiving groove portions 79 of the fatigue fitting 70 of the plug connector 2 ) Further, since it is intended to enter from the bottom to the inside of the short groove portion 55A of the plug-side housing 50, the lock bracket 30 and the fatigue bracket 70 fit into the connector as much as the entered dimensions. It will overlap in the direction. Therefore, the connector assembly can be reduced in size by the above dimensions in the connector fitting state.

Further, in the present embodiment, as described above, in the connector fitting state, when the lock bracket 30 receives the elastic support force from the elastic deformable portion 45 of the shield member 40 and brings it to the locked position, it is locked. The protruding ends of the lock protrusions 35A-1 and 35B-1 of the bracket 30 abut against the plate surfaces of the reinforcement parts 74B and 73B of the corresponding fatigue bracket 70, respectively. As a result, the reinforcing portions 74B and 73B are pressed in the terminal arrangement direction by the lock protrusions 35A-1 and 35B-1, so that movement of the plug connector 2 in the same direction is restricted. Therefore, the occurrence of the abnormal sound caused by the connectors 1 and 2 relatively reciprocating in the terminal arrangement direction and the lock protrusions 35A-1 and 35B-1 and the reinforcing parts 74B and 73B collide with each other. It is possible to prevent, and it is also possible to prevent damage to the lock protrusions 35A-1, 35B-1 and the reinforcing portions 74B, 73B.

In the modified examples shown in Figs. 8A and 8B, the fatigue bracket 170 is assumed to have two standing portions 172 standing from one base 171, but instead of this, For example, the base 171 may be formed as a shape in which the base portion 171 is divided at a central position in the width direction of the connector, that is, as a member in which one standing portion stands from one base. When the fatigue bracket is formed in this shape, two fatigue brackets are held on each end wall of the housing. At this time, the two fatigue portions are arranged so that the fatigue portions face each other in the connector width direction.

Next, the connector ejection operation will be described based on Figs. 7(A) and 7(B). When taking out the plug connector 2 in the connector fitting state with the receptacle connector 1, the pressing surface 30C-1 of the unlocking operation portion 30C of the lock bracket 30 of the receptacle connector 1 is terminal A release operation is performed by pressing in the arrangement direction toward the front (right in Fig. 7A). When the lock release operation portion 30C receives the pressing force toward the front as the release operation force, the elastic pieces 45A, 45B of the elastic deformation portion 45 of the shield member 40 contact the portion 36B of the lock bracket 30 It is deformed elastically by pressing with -1). Then, the elastic deformation portion 45 is compressed and elastically deformed, and the lock portions 35A and 35B move toward the front, as described for the connector fitting process described above.

As a result, as shown in Fig. 7(B), the lock protrusions 35A-1 and 35B-1 are received in the front short wall grooves 17B and the rear protrusion wall grooves 17F and brought to the unlocking position, , The lockable state of the lock portions 35A-1 and 35B-1 of the lock and the fatigue portions 75C and 72C of the fatigue bracket 70 of the plug connector 2 is released. Then, by lifting the plug connector 2 in the connector ejection direction (upward), the plug connector 2 is easily ejected, and the connector ejection operation is completed.

The lock portions 35A, 35B of the lock bracket 30 are located in the receiving portion 16 while the lock protrusions 35A-1, 35B-1 are located in the front end wall groove portion 17B, and It is located in the rear protrusion wall groove portion 17F. In other words, the lock portions 35A, 35B are located within the range of the receptacle-side housing 10 in the terminal arrangement direction, that is, in the longitudinal direction of the receptacle-side housing 10, and are moved within this range. Therefore, even if a large amount of protrusion of the lock protrusions 35A-1 and 35B-1 is secured, the terminals of the lock parts 35A and 35B within the above-mentioned range, regardless of the arrangement of the lock bracket 30 or not. Since the space for allowing movement in the arrangement direction can be easily secured, the enlargement of the connector in the terminal arrangement direction can be avoided.

In addition, in the present embodiment, the movement of the lock bracket 30 in the terminal arrangement direction is permitted by the elastic deformation of the elastic deformation portion 45 of the shield member 40. As described above, by providing the elastic deformation portion 45 on the shield member 40, which is a member different from the lock bracket 30, the need for the elasticity of the lock portions 35A, 35B itself is eliminated. 35A, 35B) The stiffness of itself, and the strength can be increased, so that a stable lock state can be obtained. Further, by increasing the protruding amount of the lock portions 35A and 35B, the rigidity and the strength of the lock portions 35A and 35B can be further increased, so that further improvement in stability in the locked state can be achieved. have.

In addition, in the above-mentioned Patent Document 1 mentioned in the prior art, since the elastically deformable member was provided as a separate member from the shield member, the number of components constituting the connector increases, and manufacturing cost increases. In the manufacture of the connector, there is a problem that the manufacturing process of the connector becomes complicated as the process of attaching the elastically deformable member to the housing is required. On the other hand, in this embodiment, as described above, since the elastic deformable portion 45 is integrally provided with the shield member 40, the elastic deformable member, such as Patent Document 1, is distinct from the shield member. Compared with the case of installing as a member, the number of parts can be reduced, and manufacturing cost can be suppressed. In addition, when the connector is manufactured, the elastic deformable portion 45 is also attached at the same time by the attachment of the shield member 40, so the step of attaching the elastic deformable member to the housing can be omitted, so that the manufacture of the connector is simple. Becomes

In the above-described embodiment, the plate portions 30A and 30B of the lock bracket 30 of the receptacle connector 1 are made by bending a metal plate member, but instead, the plate portion of the lock bracket is, for example, For example, it may be made by cutting a metal member as described below.

8 is a perspective view showing a lock bracket 130 according to a modification. As shown in Fig. 8, the lock bracket 130 is made of a plate portion by cutting of a rod-shaped metal member extending in the front-rear direction (terminal arrangement direction), and the unlocking operation portion is bent by bending the metal member. (130C) is made. The plate portion of the lock bracket 130 includes four plate portions of the lock bracket 30 shown in FIG. 3, that is, two outer plate portions 30A and two inner plate portions 30B in the plate thickness direction (connector width direction). It has a shape as integrated in. That is, the lock bracket 130 is a solid member in which materials are continuous in any of the connector fitting direction, the terminal arrangement direction, and the connector width direction. In Fig. 8, portions corresponding to the respective portions of the lock bracket 30 according to the above-described embodiment are denoted by the addition of "100", and their descriptions are omitted. In this lock bracket 130, the connecting portion 130D also has a shape such that the two plate portions of the connecting portion 30D of the lock bracket 30 in FIG. 3 are integrated, and the unlocking operation unit 130C is the same. It is located on one side in the connector width direction with respect to the connection portion 130D.

In the lock bracket 130, at the position of the lock protrusions 135A-1 and 135B-1 in the terminal arrangement direction, the lock protrusions 135A-1 and 135B-1 are in the thickness direction of the lock bracket 130 It is formed in a part of the entire range (in the connector width direction), and the reinforcing part 137 is formed in the remainder of the entire range. Since the lock protrusions 135A-1 and 135B-1 and the reinforcing part 137 are directly connected and integrated in the thickness direction, the lock protrusions 135A-1 and 135B-1 are more robust. Reinforced. In addition, since the plate portion of the lock bracket 130 is formed integrally with a thickness dimension that extends across the connector width direction, except for the lock protrusions 135A-1 and 135B-1 and the reinforcing portions 137 described above. , The strength of each part formed in the plate part is also improved. In this way, since greater strength is obtained over the entire plate portion, it is possible to sufficiently fight against unexpected connector output.

Here, as a modified example, the lock bracket 130 made of a metal member has been described with reference to FIG. 8, but instead, for example, a lock member having a shape shown in FIG. 8 is molded from a material such as resin. It is also possible to make.
