[Patent Document 1] Japanese Patent Laid-Open Publication No. 2009-193916

However, in the above-described conventional configuration, for example, when the cable connected to one of the connectors is erroneously pulled in the direction of being pulled away from the other connector, the force is directly applied to the rotating member through the rotating member. A spring pushing means such as a spring piece having no gap at all, as a result, there is a risk that the elastic pushing means is easily deformed and destroyed. In general, the push-pull means has the disadvantage that the strength is weaker than the usual wall portion, and it is not desirable when such force is applied.

The present invention has been developed in order to solve the problems of the prior art, and an object thereof is to provide an electrical connector device in which the connector is simultaneously fitted in the above basic structure. In the state, even if, for example, the cable connected to one of the connectors is erroneously pulled in the direction of being pulled away from the other connector, the force can be prevented from being directly applied to the elastic pushing means, and it is desirable to disperse the force. Electrical connector device.

The electrical connector device of the present invention comprises a first connector and a second connector for use in a substrate, and the first connector and the second connector are mutually engageable, and are characterized in that: The first connector has a rotation member pivotally supported by the first connector through a support portion, and when the first connector and the second connector are fitted to each other, the support portion is The center is rotated toward the second connector, and a portion connected to the support portion can be positioned on a back side of the second connector, and the first connector further has a support for pushing the support in a direction in which the fitting is performed. A portion of the portion that is coupled to the support portion and that is pushed in the direction of the fitting.

In the above-described electrical connector device, the support portion may be disposed in the first connector, and be disposed in the direction along the fitting direction to be close to the second connector. a gap between the front side portion on the side and a rear side portion provided on a side away from the second connector in a direction along the fitting direction, wherein the spring pushing means is provided on the rear side portion and the aforementioned Between the support portions, the support portion is always pushed in the fitting direction, and the support portion is always in contact with the front side portion.

Further, a plurality of cables may be mounted on the side opposite to the side of the first connector to which the second connector is fitted.

According to this configuration, the gap (distance) between the portion connected to the support portion and the back surface of the second connector can be minimized to the extent that the rotating member is attached to the second connector, and the size of the device can be reduced. For example, even if the cable connected to the first connector is erroneously pulled in the direction of being pulled away from the second connector, the first gap can be absorbed by the small gap between the portion connected to the rotating member and the back surface of the second connector. The force is then absorbed between the support portion and the gap in which the support portion is disposed, that is, the portion on the front side of the elastic pushing means, for example, the front side portion forming the gap, thereby preventing the force from being directly applied to the elastic pushing means, and effectively Prevent damage caused by the bombing method.

The rotating member may be slightly C-shaped. In this case, the entire back surface including the rotary lever can be surrounded, and the plug connector can be more effectively prevented from being detached from the socket connector.

In the above electrical connector device, the gap may be formed by an outer casing provided in the first connector. Thereby, the structure of the gap can be made stronger.

Further, in the electrical connector device, the spring pushing means may be formed by bending a part of the outer casing forming the gap toward the second connector side.

Further, in the electrical connector device, a pressing portion may be provided in the outer casing, and the support portion may be sandwiched between the bottom side of the first connector and the support portion may be pushed toward the bottom side. Thereby, the support portion can be lowered Bounce sideways to prevent floating upwards.

Thereby, the rotating member can be prevented from being accidentally floated from the substrate.

According to the present invention, even if the connector of one of the connectors is erroneously pulled in the direction of being pulled away from the other connector, the force can be prevented from being directly applied to the connector provided on one of the connectors. This force can be dispersed.

Fig. 1 is a perspective view showing the electrical connector device 1 of the present invention. The device 1 is composed of a combination of a plug connector 10 and a receptacle connector 60 that can be fitted to each other. The plug connector 10 is formed as a cable side connector, and a plurality of cables 20 can be mounted on the side opposite to the side to which the receptacle connector 60 is fitted. Further, the receptacle connector 60 is formed as a substrate-side connector and is mounted on a substrate (not shown) for use. The plug connector 10 and the receptacle connector 60 respectively have an elongated shape in the length direction (joint 11, 70 between the direction of the direction) has a bilateral symmetrical shape.

The plug connector 10 is mainly provided with: a joint 11; a casing 12 for holding the joints 11; and a metal casing 14 configured to cover the outer periphery of the casing 12; and a rotary tie rod 30 as a rotating member. The outer casing 14 of the plug connector 10 is constituted by an upper side upper side outer casing 14A covering the casing 12 and a lower side lower side outer casing 14B covering the casing 12, with the upper side outer casing 14A and the lower side outer casing 14B being used along The both end portions of the plug connector 10 in the longitudinal direction form a holding portion 15 for supporting the rotary lever 30. By the holding portions 15 holding the support portions 34 as the free end portions of the rotary lever 30, the rotary lever 30 can be pivotally supported by the outer casing 14 so as to be rotatable about the support portions 34.

In addition, the socket connector 60 is a structure other than a rotary tie rod, that is, a joint 70; a housing 62 for holding the joints 70; and a metal casing disposed to cover the outer circumference of the casing 62. 64.

The plug connector 10 and the receptacle connector 60 are inserted into the socket by the fitting portion 63 of the receptacle connector 60 through the fitting opening 63 of the receptacle connector 60 in the direction of the arrow A (hereinafter referred to as the fitting direction). The inside of the connector 60 is fitted to each other. 2 is a plan view showing the plug connector 10 and the receptacle connector 60 when the plug connector 10 and the receptacle connector 60 are in a fitted state.

When mated, the plurality of connectors 11 provided in the plug connector 10 and the corresponding connectors 70 provided in the receptacle connector 60 are in contact with each other, and the plurality of cables 20 on the plug connector 10 side are electrically connected to the substrate through the contacts. connection. Also, the outer casing 14 of the plug connector 10 is external to the receptacle connector 60 The shells 64 are in contact with each other to increase the shielding effect.

Moreover, according to the present configuration, when the plug connector 10 and the receptacle connector 60 are in the fitted state, the rotary lever 30 provided on the plug connector 10 is rotated toward the receptacle connector 60, and a part of the rotary lever 30 can be allowed (32). Positioned on the back side 46 side of the receptacle connector 60. Thereby, for example, even if the cable 20 connected to the plug connector 10 is erroneously pulled in the direction of being pulled away from the receptacle connector 60, the plug connector 10 can be prevented from being inadvertently from the receptacle connector 60 by rotating the lever 30. Being pulled away, the fitting state of the two connectors can be maintained.

3 is a perspective view showing the state in which the plug connector 10 and the receptacle connector 60 in the fitted state are removed, and the upper casing 14A is removed for convenience of explanation. Figure 4 is a partial enlarged view of one of the ends of Figure 3, and Figure 5 is a cross-sectional view taken along line 5-5 of Figure 2. The structure of the rotary tie rod 30 and its peripheral members will be described in detail with reference to the drawings.

The entire rotating lever 30 has a slightly C-shape. The rotary lever 30 includes a pair of opposing support portions 34 disposed along the longitudinal direction of the plug connector 10; similarly, an operation portion 32 disposed along the longitudinal direction of the rotary lever 30; and along the The support portion 34 is coupled to the arm portion 33 in a fitting direction A of the operation portion 32.

When the plug connector 10 and the receptacle connector 60 are fitted, the rotary lever 30 can be rotated toward the receptacle connector 60 centering on the support portion 34 held by the holding portion 15 of the plug connector 10 to connect The operation portion 32 of the support portion 34 is positioned on the side of the back surface 46 of the receptacle connector 60, and the entire portion of the receptacle connector 60 can be surrounded on the substrate by the operation portion 32 and the wrist portion 33. Thereby, the plug connector 10 can be prevented from being detached from the receptacle connector 60. However, the rotary lever 30 does not necessarily need to surround the entire receptacle connector 60, and may be disposed on at least a portion of the back surface 46 of the receptacle connector 60. For example, it may be slightly arranged on the left and right sides of the length direction of the plug connector 10. A character-shaped rotary lever (not shown) prevents the plug connector 10 from being detached from the receptacle connector 60. However, in the case of a structure that surrounds the entire back surface of the receptacle connector 60, it can be made stronger.

Further, as shown by a broken line in the figure, the drawing portion 31 made of a tape or the like may be arbitrarily attached to the operation portion 32 of the rotary lever 30, so that the rotation work can be easily performed. The rotary lever 30 is a small one having a length in the longitudinal direction of about 30 mm, and is not easily rotated. By providing the draw tape 31, the operation can be easily performed. Further, in order to prevent an increase in size of the device, the draw tape is preferably formed of a flexible material such as a tape.

The holding portion 15 for holding the support portion 34 of the rotary tie rod 30 may be formed by the outer casing 14B as shown in the illustrated embodiment. For example, it is also possible to use the lower side casing 14B of the plug connector 10 in the direction along the fitting direction A (illustrated arrow " ") is provided on the side of the front side wall 18 close to the side of the socket connector 60, and similarly in the direction of the fitting direction A by the lower side of the plug connector 10 A gap 22 is provided between the rear side walls 17 on the side away from the receptacle connector 60.

Furthermore, the front side wall 18 and the rear side wall 17 may be formed, for example, by the upper casing 14A or by the casing 12. However, it is formed by the lower casing 14B, the upper casing 14A, and the like. In other words, it is possible to make a stronger structure than in the case of using the casing 12.

The support portion 34 disposed in the gap 22 uses a spring pushing means 44 disposed between the rear side wall 17 and the support portion 34, and is always pushed in the fitting direction A, that is, from the plug connector 10 toward the socket connector 60. . As a result, the operation portion 32 connected to the support portion 34 is similarly always pushed in the fitting direction A. Further, at this time, the support portion 34 is in a state of always abutting against the front side wall 18.

Therefore, as is apparent from the above configuration, the gap a between the operation portion 32 of the rotary lever 30 and the back surface 46 of the receptacle connector 60 can be set to a minimum required for mounting the rotary lever 30 to the receptacle connector 60. The size of the device can also be reduced.

Further, in this configuration, for example, even if the plug connector 10 is erroneously pulled in the direction of being pulled away from the socket connector 60 through the cable 20 or the like, the operation portion 32 of the rotary lever 30 and the socket connector 60 can be first used. The small gap a between the back faces 46 absorbs this force, and then the portion of the front side of the support portion 34 of the rotary tie rod 30 and the plug connector 10 of the plug connector 10 is here in particular a plug connector forming part of the gap 22. Absorbing between the front side walls 18 of the 10 prevents forces from being directly applied to the bouncing means 44. As a result, it is possible to effectively prevent breakage of the bombing means and the like.

The spring pushing means 44 may be formed by a part of the outer casing 14B forming the gap 22 as shown in the illustrated embodiment, or may be a general coil spring or the like (not shown). In the illustrated embodiment, the spring pushing means 44 connects the outer casing 14B toward the socket connector in an L-shaped state having a free end. The 60 side bend is formed such that the contact area of the spring pushing means 44 with the support portion 34 becomes large.

The holding portion 15 will be described in detail with reference to Fig. 5 . As described above, the support portion 34 is provided in the holding portion 15 and is always pushed in the fitting direction A by the elastic pushing means 44, but may be further provided on the bottom side, for example, the lower side outer casing 14B and the bottom wall. Between 19, a pressing piece 24 elastically abutting on the upper side of the support portion 34 is provided, whereby the pressing piece 24 pushes the support portion 34 all the way downward, thereby preventing the support portion 34 from floating upward. The pressing piece 24 is formed in a single-arm cantilever shape by, for example, punching, bending, or the like of a part of the upper casing 14A. By providing the pressing piece 24, the support portion 44 can always be brought into contact with the bottom wall 19, so that the support portion 34 (or the rotary tie rod 30) can be held by the holding portion 15 in a more stable state. According to the above configuration, the rotary lever 30 is always rotated in a state where it is pressed against the front side wall 18 and the bottom wall 19 of the plug connector 10. Further, the support portion 34 can be pressed against the bottom side by the pressing piece 24, and therefore, it is not always necessary to form the bottom wall 19 by the lower outer casing 14B.

Next, referring to the sectional view of Fig. 5 and Fig. 1, it is understood that the inner side surfaces of the wrist portions 33 of the rotary lever 30 are connected to the socket when the rotary lever 30 is rotated toward the socket connector 60 about the support portion 34. The facing portion of the device 60 is provided with a convex portion 35, and correspondingly, on the outer side surfaces of the socket connector 60, when the rotary lever 30 is rotated toward the socket connector 60 with the support portion 34 as the center, the convex portion is convex. The portion facing the portion 35 is provided with a recess 65. When the plug connector 10 and the receptacle connector 60 are in the fitted state, the convex portions 35 are engaged with the recesses 65, whereby the rotary lever 30 can be prevented from floating. Further, the protruding portion 66 provided adjacent to the concave portion 65 is engaged with the convex portion 35 after the concave portion 65 is engaged with the convex portion 35, thereby contributing to prevention of displacement of the uneven portions.

Furthermore, the above description has been made with the plug connector 10 as the cable side connector, that is, the cable 20 is connected to the plug connector 10, but it is of course not limited thereto, in the case where no cable is provided, or in the socket connector. The present invention can also be applied to the case where the cable is provided with 60.
