Description

Male end sheath

Technical Field

The utility model relates to a public end sheath.

Background

Typically, the male end sheath includes a male end pin slot having more than one male end and a connection receiving slot for connecting the male end. In order to smoothly insert the male pin into the male pin slot, the male pin slot has a certain space allowance, and accordingly, various structures are arranged in the male pin slot to ensure that the male pin can be horizontally, centrally and firmly installed in the male pin slot. Otherwise, the connection between the male terminal and the female terminal may have poor electrical contact or even improper connection.

Disclosure of Invention

In view of the above, an object of the present invention is to provide a male end sheath capable of horizontally, centrally and firmly mounting a male end pin in a male end pin slot, and ensuring good electrical connection.

In order to achieve the above object, the utility model provides a public end sheath, including first end and second end, first end includes more than one public end contact pin groove, and the second end extends and forms the connection holding tank, the bottom in public end contact pin groove form the introducing port to interface convergence, the front end of introducing port be equipped with can retrain the second of public end contact pin between two parties and lead the limit, the front end of second lead the limit be equipped with can retrain the decurrent first lead limit with public end contact pin.

Compared with the prior art, the invention has the beneficial technical effects that: through the arrangement of the structure, the male end contact pin is gradually limited in the male end contact pin groove in a downward and then centered manner, and the introduction port converging towards the plug port is added, so that the male end contact pin can be effectively and firmly installed in the male end contact pin groove in a horizontal, centered and firm manner.

In particular, the lower wall of the pin slot at the male end is provided with a barb. Through the setting of above structure, the barb can form the back-off with the mechanism on the public end contact pin and be connected, prevents that public end contact pin from deviating from in public end contact pin groove.

In particular, a slope is arranged at the joint of the outer wall of the first end and the outer wall of the second end. Through the setting of above structure, the connection of first end and second end is not the right angle and connects, but forms the side slope, can form comparatively continuous appearance on the one hand, and user's use is experienced well, and on the other hand, the setting up of side slope can make the rubber casing be difficult to from first end or second end by the rupture, makes the sheath firmer.

Particularly, the lower wall of the connecting accommodating groove is provided with a clamping block, the clamping block is trapezoidal, and the slope of the inclined edge of the clamping block at the entering side is smaller than that of the inclined edge of the clamping block at the locking side. Through the arrangement of the structure, the fixed connection part of the male end and the female end is arranged on the inner wall of the connection accommodating groove, so that the injection mold is greatly simplified.

Particularly, two through grooves for guiding are dug out from the lower wall of the connecting accommodating groove, guide grooves for guiding are formed in the left side wall and the right side wall of the connecting accommodating groove, and the fixture block is located on the lower wall between the two through grooves. Through the setting of guide slot and logical groove, can make things convenient for the public end ground to aim at the access, in addition, set up the fixture block on two lower walls that lead to between the groove, the lower wall of this part can be towards with the below skew, can make public end easily break away from with female end, the maintenance of the connector of being convenient for is used.

In the figure: 1. a male end pin slot; 11. a barb; 12. a first guide edge; 13. a second guide edge; 14. an inlet port; 2. connecting the accommodating grooves; 21. chamfering in the circumferential direction; 22. a guide groove; 23. a clamping block; 24. a through groove; 25. chamfering; 26. side slope; 27. a lower wall.

Detailed Description

As shown in fig. 1 to 4, a male end sheath includes a first end and a second end, the first end includes more than one male end pin slot 1, the second end extends to form a connection accommodation slot 2, an introduction port 14 converging toward the pin interface is formed at the bottom of the male end pin slot 1, a second guide edge 13 capable of constraining the male end pin to be centered is arranged at the front end of the introduction port 14, and a first guide edge 12 capable of constraining the male end pin to be downward is arranged at the front end of the second guide edge 13.

The lower wall of the pin slot 1 at the male end is provided with a barb 11.

A side slope 26 is arranged at the joint of the outer wall of the first end and the outer wall of the second end.

The lower wall of the connecting accommodating groove 2 is provided with a fixture block 23, the fixture block 23 is trapezoidal, and the slope of the inclined edge of the fixture block 23 at the entering side is smaller than that of the inclined edge of the fixture block 23 at the locking side.

Two through grooves 24 for guiding are dug out at the lower wall of the connecting accommodating groove 2, guide grooves 22 for guiding are arranged on the left side wall and the right side wall of the connecting accommodating groove 2, and the fixture block 23 is positioned on the lower wall between the two through grooves 24.
