Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for preventing detachment when a male connector and a female connector are engaged.

(Prior Art) Conventionally, as shown in FIGS. 7 and 8, a connector body a of a female connector A has two annular shaft supports b, which are formed by curved projecting pieces at both ends of the connector body a.
The end portion of a locking member d, which is formed by bending an elastic wire material into a U-shape and forming a wide middle part, is attached to the annular shaft supports b and b, respectively. It is known that the horizontal bent parts e and e of the annular shaft support are fitted with a narrower interval, and the locking member d is engaged with the notch f formed on the side surface of the annular shaft support b to regulate its inclination. There is. In this case, when the male connector B is engaged with the female connector A, the locking member d of the male connector A is engaged with the notch f and is outside the movement trajectory of the male connector B during the engagement operation, and the inclination is Since this is constant, the locking member d does not get in the way, and the work of fitting the locking member d into the recess g of the male connector B can be done easily and quickly.

(Problems to be solved by the invention) In the above-mentioned conventional device, since the shaft support b of the shaft support member c is formed into an annular shape by bending the protruding piece as described above, the hole is made small in diameter. There is a limit to how far the locking member d can fit into the recess f of the male connector B due to looseness between the fitting horizontal bent part e and the fitting between the locking member d and the recess f of the male connector B. There was an inconvenience that the number of molding steps was increased.

In addition, when connector A is mounted lying on the edge of a printed circuit board, and when connector A is gripped by a robot and moved to a predetermined position, the tip of locking member d touches the top surface of connector body a. Because it is not fixed near the surface it contains, in the former case, the tip will protrude outside the end surface of the printed circuit board during storage, and in the latter case, the tip will enter the vicinity of the robot grip and cause damage to other parts. There was a problem in that the locking member was damaged or deformed when it hit the grip of the object or robot.

The present invention aims to solve the above-mentioned conventional problems.

(Means for solving the problem) A horizontal bent part at the end of the locking member, which is made by bending an elastic wire material into a U-shape and forming a wide middle part, is provided on the connector body of the connector. In a connector that is rotatably supported on a shaft supporting member and the locking member is fitted into a recess of another connector to prevent the other connector from detaching from the connector during connection, the shaft supporting member is a groove comprising two shaft support plate pieces standing upright on both sides of the shaft support plate piece, in which a locking member engages when the tip thereof is located at or near a surface X including the top surface of the connector body; It is characterized in that a groove into which the locking member engages when the tip is located on or near the surface Y including the side surface of the connector body is formed by press molding.

(Embodiments) Examples of the present invention will be described below with reference to the accompanying drawings.

1-3 illustrate a connector using one embodiment of the present invention. In the same figure, 1 is an elastic wire material such as a steel wire bent into a U-shape, the middle part of which is made wide, and the wide part is fitted into the recess of another connector B connected to connector A. A locking member 2 is provided with horizontal bent portions at both ends of the wire material, and 2 is a shaft support member provided on both sides of the upper surface of the connector body 3 to rotatably support the locking member 1. be. This shaft support member 2 is provided with two shaft support plate pieces 4 that stand up on both sides of the plate member, and a hole 5 for pivotally supporting the horizontal bent portion of the locking member 1 is bored in the shaft support plate piece 4. The tip also includes a groove 6 into which the locking member 1 fits when the tip is located on the plane X that includes the top surface of the connector body 3 (or when it is positioned near the plane A groove 7 is formed into which the locking member 1 fits when positioned on the plane Y (or may be positioned near the plane Y). This shaft support member 2 was produced by simple press molding.

Thus, when transporting this connector A by placing it in a magazine 8 as shown in the fourth figure, for example, the locking member 1 is locked in the groove 7 of the shaft support member 2, and the connector is inserted in this state. Place A into magazine 8.

Further, as shown in Figure 5, when the connector A is mounted lying on the edge of the printed circuit board 9, the locking member 1 is engaged with the groove 6 of the shaft support member 2 when not connected to another connector. The tip of the locking member 1 is prevented from protruding outward from the end surface of the printed circuit board 9, so that the locking portion does not get deformed or damaged by hitting other objects during storage or the like.

Similarly, when this connector A is gripped by a robot and attached to a predetermined position of an electronic device,
The locking member 1 is engaged with the groove 6 of the shaft support member 2 so that there is no problem when the robot grasps the connector A.

In the embodiment described above, the grooves 6 and 7 formed in the shaft support plate piece 4 of the shaft support member 2 were formed by recessing by press molding, but as shown in FIG. The grooves 6, 7 as described above can be formed by a pair of substantially hemispherical protrusions 10, 10 formed at an interval substantially equal to the diameter of the strip.

(Effects of the invention) As described above, according to the invention, the shaft support material can be easily press-formed, and when the connector is mounted lying on the edge of the printed circuit board, the connector can be mounted on the electronic device by a robot. When transporting the connector in a magazine, the work can be carried out smoothly, and the locking member is not damaged or deformed.
