[0002] An electrical connector is a coupling device that connects electrical terminals to form a circuit. It serves to connect or disconnect current or signals. An electrical connector consists of a fixed-end electrical connector, i.e., a female contact, and a free-end electrical connector, i.e., a male contact.

[0003] Electrical connectors are often connected using threaded mounting. However, the direct connection structure of electrical connectors has poor limiting effect. During use, problems such as loosening when the socket and plug are turned in the same direction and poor connection and mating stability can easily occur, resulting in loose connection and affecting the stability of the electrical connector connection.

[0004] There is an urgent need for an anti-rotation electrical connector assembly to address the technical deficiencies mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an anti-rotation electrical connector assembly to solve the problem of poor connection limiting structure and easy loosening mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-rotation electrical connector assembly, comprising a first housing and a second housing. A first contact element is installed inside the first housing. A first threaded groove is provided near the front end of the outer surface of the first housing. A connecting external threaded groove is provided near the rear end of the outer surface of the first housing. A limiting cylinder is installed inside the second housing. A connecting sleeve is movably connected to the front end of the second housing. A second contact element is installed inside the limiting cylinder. A limiting block is fixedly connected to the outer surface of the limiting cylinder. A limiting groove is provided inside the first housing. A connecting internal threaded groove is provided on the inner wall of the connecting sleeve. A second threaded groove is provided near the rear end of the outer surface of the limiting cylinder. A splicing block is fixedly connected to the outer surface of the limiting cylinder. A splicing groove is provided on the inner side of the second housing.

[0007] As a further technical solution of this utility model, the limiting blocks are provided in four sets, and the limiting blocks are arranged in a ring outside the limiting cylinder, and the limiting blocks are embedded in the limiting slot.

[0008] As a further technical solution of this utility model, the connecting external thread groove and the connecting internal thread groove are threadedly connected, and the rear end of the first housing can be inserted into the interior of the second housing.

[0009] As a further technical solution of this utility model, the splicing card block is provided in eight sets, and the splicing card block is embedded in the splicing card slot.

[0010] As a further technical solution of this utility model, the threads of the first threaded groove and the second threaded groove are opposite, and the number of pairs of the first contact and the second contact are the same.

[0011] As a further technical solution of this utility model, the exterior of the second housing is provided with anti-slip texture.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the anti-rotation electrical connector assembly not only realizes the functions of easy positioning and anti-loosening, and the function of firm connection, but also realizes the function of enhanced protection.

[0013] By configuring a first contact element, a first housing, a second contact element, a limiting cylinder, a second housing, a limiting block, a limiting slot, a splicing block, a splicing slot, and a connecting sleeve, during connection, the rear end of the first housing is inserted into the interior of the connecting sleeve. The limiting slot on the inner side of the first housing splices with the limiting block on the outer side of the limiting cylinder. Subsequently, the connecting sleeve rotates to connect with the first housing. The first contact element and the second contact element achieve a stable limiting connection through the limiting block and the limiting slot. The second contact element is firmly installed by the splicing block on the outer side of the limiting cylinder engaging with the splicing slot of the second housing. This structure achieves a connection function that facilitates limiting and prevents loosening.

[0014] By providing a first threaded groove, a connecting external threaded groove, a second threaded groove, and a connecting internal threaded groove, the electrical connector requires the first housing to be connected to the second housing during assembly. The first housing and the connecting sleeve are screwed together by the connecting external threaded groove and the connecting internal threaded groove. The threads of the first threaded groove and the connecting external threaded groove are in the same direction, while the threads of the first threaded groove and the second threaded groove are in opposite directions. When connected, opposite screwing forces are generated, which can better screw and fix the first housing and the second housing. This structure achieves the function of easy and firm connection.

[0015] By incorporating a first housing, a second housing, and anti-slip textures, the first and second housings can protect the first and second contacts. The force applied during connection to the outside of the first and second housings will not affect the contacts. The anti-slip textures on the outside of the second housing can improve the stability of the knob installation. This structure achieves both enhanced protection and easy connection.

The limiting groove 11 on the inner side of the first housing 3 is spliced ​​with the limiting block 9 on the outside of the limiting cylinder 6. Then, the connecting sleeve 15 is rotated to connect with the first housing 3. The first contact 1 and the second contact 5 are stably limited and connected through the limiting block 9 and the limiting groove 11. The second contact 5 is firmly installed by fitting the splicing block 13 on the outside of the limiting cylinder 6 with the splicing groove 14 of the second housing 7.

[0025] The external threaded groove 4 and the internal threaded groove 10 are threadedly connected. The rear end of the first housing 3 can be inserted into the interior of the second housing 7. The threads of the first threaded groove 2 and the second threaded groove 8 are opposite. The number of pairs of the first contact 1 and the second contact 5 are the same.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, during installation, the first housing 3 and the connecting sleeve 15 are screwed together by the connecting external thread groove 4 and the connecting internal thread groove 10. The threads of the first thread groove 2 and the connecting external thread groove 4 are in the same direction, while the threads of the first thread groove 2 and the second thread groove 8 are in opposite directions.

The threads of the first threaded groove 2 and the external threaded groove 4 are in the same direction, while the threads of the first threaded groove 2 and the second threaded groove 8 are in opposite directions. This creates opposing screwing forces during connection, allowing for better screwing and fixing of the first housing 3 and the connecting sleeve 15. The first housing 3 and the second housing 7 provide protection for the first contact 1 and the second contact 5 during connection. The force applied to the outside of the first housing 3 and the second housing 7 will not affect the contact parts. The anti-slip texture 12 on the outside of the second housing 7 can improve the stability of the knob installation. When connecting, the rear end of the first housing 3 is inserted into the inside of the connecting sleeve 15. The limiting groove 11 on the inside of the first housing 3 is spliced ​​with the limiting block 9 on the outside of the limiting cylinder 6. Then the connecting sleeve 15 is rotated to connect with the first housing 3. The first contact 1 and the second contact 5 are stably limited and connected through the limiting block 9 and the limiting groove 11. The second contact 5 is firmly installed by the splicing block 13 on the outside of the limiting cylinder 6 and the splicing groove 14 of the second housing 7.
