Description

Fixture

The invention relates to a jig, in particular to a jig for providing a reference role for a process of product assembly and the like.

Existing electronic devices often require fixtures to provide a reference role in manufacturing, assembly, etc., while conventional fixtures are mainly made of plastic materials. In order to improve the retention of traditional plastic fixtures and electrical connector frames, it is usually traditional. The plastic jig is provided with a rib structure to increase hard interference with the frame of the electrical connector, and is provided with a snap structure to be engaged with the metal case. However, in the initial state, the retaining force of the plastic jig and the frame of the electrical connector can meet the requirements, but if the plastic jig is subjected to high temperature after welding, the plastic jig will be deformed due to excessive temperature, thereby causing the jig and electricity. The retention of the connector frame is reduced. At the same time, the rib structure on the plastic jig may damage the frame of the electrical connector when it hardly interferes with the frame of the electrical connector.

In view of this, it is necessary to provide a new jig to overcome the above problems.

It is an object of the present invention to provide a jig that is resistant to high temperatures, has good elasticity, and is low in cost.

The jig of the present invention can be realized by the following technical solution: a jig assembled with an electrical connector and a reference plate, the electrical connector being located at one side of the jig, comprising an insulating body, assembled in insulation a conductive terminal in the body and a metal casing shielded on a periphery of the insulating body, the reference plate being located on the other side of the fixture, the reference plate The rear surface is provided with a snap groove, the jig is made of a metal material, and the front end of the lower wall of the jig is bent forward to form a fixed arm, and one end of the jig is abutted against the reference by the fixed arm The other end of the jig is engaged with the metal casing by a snap connection.

Compared with the prior art, the present invention is made of a metal material, has the characteristics of high temperature resistance, good elasticity, and the like, and does not deform under a high temperature environment, thereby ensuring the retention between the fixture and the frame of the electrical connector. At the same time, the foregoing fixture eliminates the design of the rib structure and reduces the risk of the fixture damaging the frame of the electrical connector. Moreover, the above-mentioned jig has better elasticity, and the corresponding structure can be increased according to the customer's demand, thereby increasing the diversity and practicability of the product.

The specific structure of the first embodiment of the jig of the present invention can be referred to as the first to sixth figures. The jig 4 in this embodiment is used to provide a reference role for the assembly of products such as electrical connectors. The first to sixth figures disclose the assembly fit of the jig 4 with the electrical connector and the reference plate 5.

Referring to the first and third to fourth figures, the jig 4 is stamped from a metal material and has a semi-closed frame shape. The upper wall of the jig 4 is provided with a card hole 41, and the front end of the upper wall thereof extends upward to form a first baffle 42, and the rear end thereof extends downward to form a second baffle 46. The front end of the lower wall of the jig 4 vertically extends downward to form a positioning plate 43 and extends forward to form a fixed arm 44. The rear end of the lower wall of the jig 4 is provided with a hook portion 45.

Referring to FIG. 2 to FIG. 5 , the electrical connector includes an insulative housing 1 , a plurality of conductive terminals 2 assembled on the insulative housing 1 , and a metal housing 3 shielded from the periphery of the insulative housing 1 .

Referring to the third and fourth figures, the insulative housing 1 includes a body portion 11 and an extending portion 12 extending forwardly from the body portion. The front surface of the extending portion 12 is recessed inwardly to form a receiving cavity 13 The rear surface of the portion 11 is provided with a plurality of receiving holes 14 , and the receiving holes 14 are in communication with the receiving cavity 13 . The upper wall of the main body portion 11 is provided with a recess 15 , and the recess 15 is provided with a square through hole 16 , and the through hole 16 communicates with the receiving cavity 13 .

Referring to the third and fourth figures, the conductive terminal 2 includes an abutting portion 21 and a bent portion 22. The abutting portion 21 is received in the receiving cavity 13 of the insulative housing 1 through the receiving hole 14 . The bent portion 22 extends upward from the rear end of the mating portion 21 in an arc shape and then extends vertically downward. An elastic piece 31 is disposed on the upper wall of the metal casing 3, and an intermediate portion of the elastic piece 31 is bent downward into an arc shape. The aforementioned reference plate 5 rear table The surface is provided with a snap groove 51.

When the jig 4 is received in the receiving cavity 13 of the insulative housing 1 , the first baffle 42 and the positioning plate 43 of the jig 4 abut against the front surface of the extending portion 12 of the insulative housing 1 . Then, the jig 4 is stuck against the reference plate 5, and a part of the fixing arm 44 is received in the locking groove 51 of the reference plate 5, and the end of the fixing arm 44 extends to the upper surface of the reference plate 5. The positioning plate 43 abuts against the rear surface of the reference plate 5, and then the abutting portion 21 of the conductive terminal 2 passes through the receiving hole 14 of the insulative housing 1, and the bent portion 22 is located outside the insulative housing 1. Finally, the metal casing 3 is assembled from the rear to the front of the insulative housing 1 and wrapped around the body portion 11.
