Description

Technical Field

[0001] The utility model relates to the technical field of connector housings, and specifically relates to a single-sided and double-sided locking protection housing. Background Technique

[0002] A connector is also called a coupler. In China, it is also called a connector and a socket, generally referring to an electrical connector. That is, a device that connects two active devices and transmits current or signals. Connectors are usually used with housings, and the housing plays a protective role for the connector.

[0003] The currently common connector housing includes an upper shell and a lower shell. A clamping rod is provided on the upper shell, and a clamping ring is rotatably provided on the lower shell. The lower shell is inserted into the upper shell, and the clamping ring is rotated. The clamping ring is clamped on the clamping rod, and the lower shell is fixed on the upper shell.

[0004] For the above technical conditions, there is also a defect that the lower shell is fixed on the upper shell by relying on the clamping ring being clamped on the clamping rod, but the stability of the clamping ring is not good enough, and it is easy to be separated from the clamping rod under force, resulting in the lower shell being easily detached from the upper shell.

[0005] Based on this, the utility model designs a single-sided and double-sided locking protection housing to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a single-sided and double-sided locking protection housing to solve the above technical problems.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A single-sided and double-sided locking protection housing, including the housing of the connector, the housing includes an upper shell and a lower shell, the lower shell is connected to the upper shell, the upper shell is threadedly connected with a clamping rod, the lower shell is rotatably provided with a clamping ring, the clamping ring is clamped on the clamping rod, the upper shell is provided with a threaded hole, the clamping ring is fixedly connected with a fixing plate, the fixing plate is provided with a fixing hole, and a threaded rod is inserted into the fixing hole, and the threaded rod is threadedly connected in the threaded hole.

[0008] Preferably, a fixing groove is provided on the clamping rod.

[0009] Preferably, a rubber ring is sleeved on the clamping rod, and the rubber ring is between the clamping rod and the upper shell.

[0010] Preferably, a tightening ring is sleeved on the threaded rod, and the tightening ring is between the upper shell and the fixing plate.

[0011] Preferably, an auxiliary plate is fixedly provided on the clamping ring, and the auxiliary plate is below the fixing plate.

[0012] In summary, the present application has the following beneficial technical effects: When the housing of the connector is installed on the connector, the clamping ring is clamped on the clamping rod, the lower housing is fixed on the upper housing, the fixing holes on the fixing plate are aligned with the threaded holes on the upper housing, the threaded rod is inserted into the fixing holes of the fixing plate, and then the threaded rod passes through the pressing ring and is threadedly connected to the threaded hole. At this time, the clamping ring is fixed in the upper housing by the threaded rod and is not likely to fall off the clamping rod under force, improving the stability of the clamping ring and achieving the effect of improving the stability of the clamping ring of the connector housing.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] The following will further describe the present application in detail with reference to the Figures 1-4 accompanying drawings.

[0022] A single-sided and double-sided locking protective housing, including the housing of the connector. The housing includes an upper housing 1 and a lower housing 5, and the lower housing 5 is connected to the upper housing 1. The upper housing 1 is threadedly connected with a clamping rod 6, and two groups of clamping rods 6 are mirror-symmetrically arranged on the upper housing 1. A clamping ring 4 is rotatably arranged on the lower housing 5. By rotating the clamping ring 4, the clamping ring 4 is clamped on the clamping rod 6, and the lower housing 5 is fixed on the upper housing 1.

[0023] On one side of the upper housing 1 away from the clamping rod 6, a threaded hole 10 is opened. On the side of the clamping ring 4 close to the upper housing 1, a fixing plate 9 is fixedly arranged. The fixing plate 9 is integrally formed with the clamping ring 4. A fixing hole 11 is opened on the fixing plate 9, and a threaded rod 8 is inserted into the fixing hole 11. The threaded rod 8 is threadedly connected in the threaded hole 10, and the fixing rod makes it difficult for the clamping ring 4 to fall off the clamping rod 6 due to force.

[0024] At one end of the clamping rod 6 away from the upper housing 1, a fixing groove 3 is opened. The fixing groove 3 facilitates screwing the clamping rod 6 onto the upper housing 1. An auxiliary plate 7 is fixedly arranged on the clamping ring 4. The auxiliary plate 7 is below the fixing plate 9, and the auxiliary plate 7 is integrally formed with the clamping ring 4. When the clamping ring 4 is clamped on the clamping rod 6, the auxiliary plate 7 facilitates exerting force.

[0025] A rubber ring 12 is sleeved on the clamping rod 6. The rubber ring 12 is between the clamping rod 6 and the upper housing 1. When the clamping rod 6 is screwed tightly, one side of the rubber ring 12 abuts against the upper housing 1, and the other side abuts against the clamping rod 6. A tightening ring 2 is sleeved on the threaded rod 8. The tightening ring 2 is between the upper housing 1 and the fixing plate 9. The tightening ring 2 is made of rubber material. When the threaded rod 8 is tightened, one side of the tightening ring 2 abuts against the upper housing 1, and the other side abuts against the fixing plate 9. The tightening ring 2 plays a buffering role.

[0026] The implementation principle of this embodiment is as follows: When the housing of the connector is installed on the connector, the clamping ring 4 is clamped on the clamping rod 6, and the lower housing 5 is fixed on the upper housing 1. The fixing hole 11 on the fixing plate 9 is aligned with the threaded hole 10 on the upper housing 1. The threaded rod 8 is inserted into the fixing hole 11 of the fixing plate 9, and then the threaded rod 8 passes through the tightening ring 2 and is threadedly connected in the threaded hole 10. At this time, the clamping ring 4 is fixed in the upper housing 1 by the threaded rod 8 and is not likely to fall off the clamping rod 6 due to force, and the stability of the clamping ring 4 is improved, achieving the effect of improving the stability of the clamping ring 4 of the connector housing.
