Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a composite electrical connector. Background Technology

[0002] A circular electrical connector is a connector with a cylindrical structure and a circular mating surface. Due to its small size, light weight, and quick connection and disconnection capabilities, circular electrical connectors are widely used for electrical connections between instruments and electronic equipment. Currently, circular electrical connectors on the market are mainly divided into two types: one with a metal shell, which has the advantage of long service life and can be used in harsh environments; however, the high cost of metal materials and processing results in a high overall cost. The other type has a pure plastic shell, which has the advantage of low manufacturing cost, but a shorter service life and cannot be used in harsh environments. Therefore, existing circular electrical connectors cannot simultaneously achieve both long service life and low manufacturing cost, hindering their widespread application. Summary of the Invention

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a composite electrical connector that improves the service life and reduces the production cost of the composite electrical connector by setting a first connecting part and a second connecting part made of different materials.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0005] A composite electrical connector includes: a first connecting portion and a second connecting portion; the first connecting portion includes an insulating block, a connecting block, and an outwardly extending mounting portion, the mounting portion and the connecting block being located at the upper and lower ends of the insulating block, respectively, and the insulating block having a through hole for accommodating a plug; a positioning block and a plug are also provided on the outer side of the insulating block; the second connecting portion includes a protective ring, a connecting ring, and a fixing block for fixing the protective ring, the fixing block being distributed on the side of the protective ring; the connecting ring is located below the protective ring, and the connecting ring has a groove that mates with the positioning block and a snap fastener that mates with the plug; the first connecting portion and the second connecting portion are made of different materials; the protective ring is fixedly connected to the first connecting portion by inserting the plug into the snap fastener.

[0006] The aforementioned composite electrical connector has at least the following beneficial effects: by setting a first connecting part and a second connecting part, it is convenient to select insulating blocks and protective rings made of different materials according to the installation environment, thereby improving the compatibility and ease of use of the composite electrical connector and reducing the production cost of the composite electrical connector; by setting a protective ring and a connecting ring, the protective ring can be fixedly connected to the connecting ring by inserting a plug into the buckle, ensuring the connection stability of the first connecting part and the second connecting part, and improving the structural integrity and service life of the composite electrical connector.

[0007] Furthermore, the multiple through holes are evenly distributed on the insulating block, and the axial direction of the through holes is parallel to the axial direction of the protective ring. This structure ensures that the through holes can stably accommodate multiple plugs, avoiding short circuits caused by contact between plugs and improving the service life of the composite electrical connector.

By setting the fixing blocks, the connecting ring can be quickly and stably fixed to external devices, avoiding the need for rivets on the outside of the connecting ring, improving the production efficiency of composite electrical connectors, and ensuring the operational stability of composite electrical connectors.

[0009] Furthermore, the fixing block includes a first slider and a second slider connected to each other; the height of the first slider gradually increases along the direction close to the second slider, and the side of the second slider away from the first slider is arc-shaped. By setting the first slider and the second slider, it is ensured that the fixing block can be quickly and accurately inserted into the external device by the first slider and fixed by the second slider, thereby improving the ease of use of the composite electrical connector.

[0010] Furthermore, the outer side of the connecting block is provided with threads.

[0034] The working principle of this utility model will be further explained below.

[0035] During the production process, based on the usage environment of the composite electrical connector, different types of metal materials are selected for die casting to form the second connecting part 200. The fixing block 230 is distributed on the side of the protective ring 210, and the connecting ring 220 is located below the protective ring 210. The connecting ring 220 has a groove 221, a snap-fit ​​222, and a connecting hole 223. Specifically, the protective ring 210, the connecting ring 220, and the fixing block 230 are integrally formed, eliminating the need for additional riveting operations and simplifying the production process of the composite electrical connector. Next, the second connecting part 200 is placed into a mold, fixing the connecting ring 220 within the mold, and then injection molding or potting is performed. Insulating material is injected into a mold under pressure to form the first connecting part 100. A positioning block 140 is inserted into a groove 221, a plug 150 is inserted into a snap-fit ​​222, and a connecting strip 160 is inserted into a connecting hole 223, so that the second connecting part 200 is stably fixed to the upper end of the first connecting part 100.

The two sliders 232 ensure that the fixing block 230 can be quickly and accurately inserted into the external device via the first slider 231 and fixed via the second slider 232, improving the ease of use of the composite electrical connector. The thread 121 ensures that the first connecting part 100 can be quickly and stably fixed to the local device via the connecting block 120, preventing the first connecting part 100 from loosening during operation and improving the working stability of the composite electrical connector. The mounting hole 131 facilitates the quick and stable fixing of the mounting part 130 to the local device via bolts, improving the installation stability of the first connecting part 100.
