Description

Connector anti-loose structure

This creation is related to an electrical connector, especially a connector anti-loose structure.

As shown in the first figure, a female connector 1a for plug-in connection, such as a cable connector 2a, is conventionally provided, which mainly has a terminal block 10a, and a plurality of terminals 11a are disposed on the terminal block 10a. And the terminal block 10a is assembled for the connector 20a of the mated cable connector 2a, and the connector 20a has a corresponding terminal 21a for contacting the terminal 11a of the female electrical connector 1a; In the assembly with the terminal block 10a, a recess 22a into which the terminal block 10a is inserted is formed in the joint 20a to achieve the mating engagement.

However, since there must be some tolerances in the assembly, it means that there is a gap d between the inner side wall of the recess 22a and the side edge 12a of the terminal block 10a, and when the connector 20a of the cable connector 2a may be due to the weight of the cable or When other external factors are biased to one side, as shown in the second figure, the gap d between the joint 20a and the terminal block 10a is concentrated on the other side to enlarge the gap, so that the female electrical connector 1a is easily caused. The terminals 11a, 21a between the cable connectors 2a have problems such as poor contact or contact failure.

In view of this, the creator is trying to improve and solve the above-mentioned shortcomings, and he has devoted himself to researching and cooperating with the application of theory, and finally proposed a creation that is reasonable in design and effective in improving the above-mentioned defects.

The main purpose of the present invention is to provide a connector anti-loose structure which is designed to pass through the guiding surface so that the male and female connectors are less likely to be offset or misaligned during the jointing, resulting in poor contact between the terminals or Problems such as contact failure.

In order to achieve the above object, the present invention provides a connector anti-loose structure, comprising an insulative housing, a metal housing, and a plurality of terminals; the insulative housing has a terminal block for each terminal to be disposed on the surface of the terminal block. The metal case is covered on the outside of the insulating body, and a hollow socket portion is formed outside the terminal block, so that the terminal block is located in the socket portion; wherein the terminal block forms a guiding surface at least one side edge, the guiding The side edge of the terminal block is formed in a undulating type in which the rear end of the terminal block is protruded and the front end is concave.

In order to further disclose the features and technical contents of the present invention, please refer to the following detailed description and drawings of the present invention. However, the drawings are only for reference and description, and are not intended to limit the creation.

Please refer to the third figure, which is a schematic diagram of the three-dimensional appearance of the creation. The present invention provides a connector anti-loose structure, the connector 1 can be used to interface with a cable connector 2 for the purpose of telecommunications connection (ie, as shown in the fourth figure); the connector 1 includes an insulative body 10. A metal housing 11 and a plurality of terminals 12; wherein:

The insulative housing 10 has a terminal block 100 protruding forwardly for allowing the terminals 12 to be disposed on the surface of the terminal block 100, such as an upper surface and/or a lower surface. The metal casing 11 is wrapped on the outside of the insulative housing 10, and a hollow socket portion 110 is formed outside the terminal housing 100 to form an insertion port 111 with the terminal block 100 for docking the cable connector 2. It can be inserted into the insertion port 111 to be assembled.

As shown in the fourth and fifth figures, the cable connector 2 has a connector 20 that can be inserted into the insertion port 111, and is also covered with a metal shell 21 outside the connector 20, and the connector 20 is Also formed with a recess 200 that can be inserted into the terminal block 100, the joint 20 is provided with a plurality of terminals 22 on the surface corresponding to the recess 200, so that when the cable connector 2 is mated with the connector 1, The terminals 11 and 22 for both of them are in contact with each other to be in an electrically conductive state.

Referring to the fifth and sixth figures, the present invention mainly forms a guiding surface 101 at least one side of the terminal block 100 of the connector 1. The guiding surface 101 is connected to the terminal block 100. The side edge is formed in a undulating manner in which the rear end of the terminal block 100 is protruded and the front end is concave. The rib portion 102, a guiding portion 103, and a portion may be further sequentially included from the rear end of the terminal block 100 to the front end thereof. The engaging portion 104 is located at the rear end of the terminal block 100, the engaging portion 104 is located at the front end of the terminal block 100, and the guiding portion 103 is located between the protruding portion 102 and the engaging portion 104, thereby forming a The guide surface 101 described.

Therefore, by the above-mentioned structural composition, the anti-loose structure of the present connector can be obtained.

Accordingly, as shown in the sixth figure, when the cable connector 2 is inserted into the connector 1 of the present invention, the guiding surface 101 of the terminal block 100 can provide the connector 20 of the cable connector 2 with its notch The side edge 201 of the 200 is inserted along the guiding surface 101, and since the guiding surface 101 is protruded at the rear end of the terminal block 100, the joint 20 can be provided with a good assembly or anti-loose effect, and the cable can be prevented from being generated. The connector 2 is offset or offset, so that the terminals 11 and 21 are not caused to cause contact failure or contact failure. At the same time, the guiding surface 101 is concave at the front end of the terminal block 100, which can also contribute to the cable. The connector 20 of the connector 2 is inserted into the terminal block 200 so as not to be easily inserted because the protruding rib 102 of the guiding surface 101 is in close contact with the side edge 201 of the recess 200, and since the guiding surface 101 is in the protruding rib 102 The guiding portion 103 is provided between the engaging portions 104 to facilitate the insertion of the notch 200 of the joint 20 by the engaging portion 104, and is gradually guided to the protruding rib portion 102 through the guiding portion 103 to smoothly complete the insertion operation.

It should be noted that the embodiment of the present invention is that the guiding surface 101 is formed on both side edges of the terminal block 100, so that the terminal block 100 can be formed at a wider end and a narrower front end. The wide and narrower type can strengthen the connection with the cable connector 2 or the anti-loose effect.

In summary, this creation is a rare new creative product, which can achieve the intended use, but solve the lack of knowledge, and because of its novelty and progress, it fully meets the requirements of new patent applications. To file an application in accordance with the Patent Law, please check and grant the patent in this case to protect the rights of the creator.

However, the above description is only a preferred and feasible embodiment of the present invention, and thus the scope of the patent of the present invention is not limited thereby, and therefore equivalent structural changes made by using the present specification and the contents of the drawings are equally included in the present invention. Within the scope of creation, he is given to Chen Ming.
