Description

Plug-type readily releasable connector

Technical Field

The utility model relates to a connector technical field, in particular to plug-type readily releasable connector.

Background

Push-pull connectors are widely used in equipment in the fields of medical machinery, communication telephones, interphones, small terminals, satellite telephony, and the like, because of their characteristics of small size, convenient operation, electromagnetic interference resistance, environmental resistance, simple operation, and the like. The housings of conventional push-pull connectors are all assembled together by two parts.

However, in the prior art, since the two housings are combined together by parts, the problem of poor sealing performance of the easily separable connector is inevitable, and further improvement is needed.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a plug-type readily releasable connector for the connector has better leakproofness.

In order to solve the technical problem, the utility model discloses a technical scheme does:

a push-pull type frangible connector comprising: the plug comprises a positioning ring and a plug shell, wherein the positioning ring is sleeved in the plug shell in an interference fit manner, an insulator is arranged in the positioning ring, a plurality of contact pins are uniformly inserted in the insulator, the circumferential side of the insulator is symmetrically provided with two grounding rings in the plug shell, a wire pressing ring contacted with the grounding rings is arranged in the plug shell, and a tail nut is connected to the outer side of the plug shell in a threaded manner.

Preferably, a sleeve is arranged in the tail nut.

Preferably, a gasket is arranged in the sleeve.

Preferably, the radius of the wire pressing ring becomes gradually larger in a direction away from the ground ring.

Preferably, a plurality of strip-shaped holes are formed in the peripheral side of the grounding ring along the extending direction of the grounding ring.

Compared with the prior art, the utility model has the advantages that the plug inner sleeve is inserted into the socket shell in an interference fit manner, so that the integrity of the connector in design is ensured, and the connector has better air sealing performance and water tightness, and has the characteristics of small volume, good shielding effect, electromagnetic interference resistance, good environment resistance and high reliability; simultaneously, the novel anti-skidding appearance design in product surface, convenient operation during the plug.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 and 2, a push-pull type frangible connector comprises: the positioning ring 1 is sleeved in the plug shell 2 in an interference fit mode, and therefore the connector has good air tightness and water tightness. Referring to fig. 2 and 3, an insulator 3 is fitted over the positioning ring 1, and the insulator 3 itself is nonconductive.

Referring to fig. 4, one end of the insulator 3 can extend out of the wire pressing ring 7, a plurality of pins 5 are uniformly inserted into the insulator 3, and both ends of the pins 5 can extend out of both ends of the insulator 3.

Further, two ground rings 6 are provided on the periphery of the extension of the insulator 3, the two ground rings 6 are provided around the insulator 3, and the ground rings 6 are provided in the plug housing 2 so as to fix the ground rings 6. In addition, a wire pressing ring 7 is arranged in the plug housing 2, and one side of the wire pressing ring 7 close to the positioning ring 1 is abutted with the grounding ring 6.

Meanwhile, referring to fig. 3, in order to position the wire pressing ring 7, the radius of the wire pressing ring 7 is smaller as the wire pressing ring is closer to the grounding ring 6, and meanwhile, an inclined ring is installed on one side of the grounding ring 6 close to the wire pressing ring 7, so that one end of the wire pressing ring 7 can be inserted into the inclined ring, and on the other hand, a worker can conveniently sleeve the wire pressing ring 7 in the two grounding rings 6.

In this embodiment, a tail nut 8 is screwed on the outer side of the plug housing 2, and the positioning ring 1 is located in the tail nut 8.

In order to reduce the possibility of horizontal movement of the positioning ring 1, a sleeve 9 is arranged in the tail nut 8, and one end of the sleeve 9 is abutted to one end of the positioning ring 1, which is located in the tail nut 8, so that the possibility of spontaneous movement of the positioning ring 1 is effectively reduced.

Meanwhile, a gasket 10 is arranged in the sleeve 9, and has an anti-skid function.

In addition, a plurality of bar holes 61 have been seted up along the extending direction of ground ring 6 on the week side of ground ring 6, and the quantity of bar holes 61 is a plurality of and arranges along the circumferencial direction of ground ring 6, and when plug housing 2 emboliaed, ground ring 61 inwards takes place deformation to conveniently embolia plug housing 2, on the other hand, also practiced thrift the material.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
