Description

Rubber-covered integrated plug

Technical Field

The utility model relates to a connector plug, in particular to an encapsulated integrated plug.

Background

The conventional connecting plug is generally assembled or assembled by an inner core and an external plastic shell which wrap the pin, so that the protective performance of the plug is greatly reduced, and the plug does not make a clear indication of the plugging direction for a user, so that the plug is easily damaged or in poor contact due to plugging errors caused by the use of the plug.

Disclosure of Invention

In view of the above, the utility model provides an encapsulated integrated plug, which is characterized in that a female pin contact is fixed with a cable core, and the female pin contact and the cable core are wrapped by a die to form the integrated plug, so that the protection performance of the plug can be remarkably provided.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the rubber-covered integrated plug comprises a wire core, a contact pin connected with the wire core, a shell integrally wrapping the wire core and the contact pin, a plug-in part for connecting the plug or the socket is integrally arranged on one side of the front end of the shell, a jack for inserting the contact pin is formed in the plug-in part, and the contact pin is fixed in the jack.

Further, the outer diameter of the plug-in part is reduced inwards to form a step structure with the shell.

Further, a sealing gasket is sleeved on the plug-in part.

Further, the side of the plug-in part is provided with a positioning groove, and the number of the positioning grooves can be one or a plurality of.

Further, the length of the positioning groove is smaller than the length of the plug-in part.

Further, at least two positioning grooves are formed in the side face of the plug-in connection portion, and the positioning grooves are different in shape or size and used for identifying plug-in connection positions.

Further, a positioning hole is formed in the other side of the front end of the shell, and a positioning piece such as a positioning bolt is arranged in the positioning hole.

Further, the outer wall of the rear end of the shell is in a step structure.

The beneficial effects of the utility model are as follows: the cable and the contact pin which are wrapped with the wire core are integrally wrapped in the shell through injection molding, so that the protection performance of the shell on the wire core and the female pin can be greatly improved, and the protection level of the product is greatly improved; through set up the constant head tank on grafting portion, can avoid grafting mistake to cause the risk of product damage, and through set up sealed pad on grafting portion, then can further improve the leakproofness of product, the setting element then can guarantee the fastness after the product grafting.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and 2, the encapsulated integrated plug comprises a wire core 1, a contact pin 2 connected with the wire core 1, and a shell 3 integrally wrapping the wire core 1 and the contact pin 2, wherein one side of the front end of the shell 3 is integrally provided with a plug-in part 4 for connecting a socket, a jack 5 for inserting the contact pin 2 is formed in the plug-in part 4, the contact pin 2 is fixed in the jack 5, and the outer diameter of the plug-in part 4 is reduced inwards to form a step structure with a shell, so that the plug-in part is convenient to plug in with the socket.

Specifically, a sealing gasket 6 is sleeved on the plug-in part 4, so that the sealing performance of the contact part of the plug-in part 4 and the socket is improved, and the protection capability of the plug is improved.

As an embodiment, four positioning grooves 7 are uniformly formed on the side wall of the plugging portion 4, and one positioning groove 7 has a shape or size different from the other three positioning grooves 7, in this embodiment, the shape of one positioning groove 7 is rectangular, and the shape of the remaining three positioning grooves 7 is semicircular.

As an alternative embodiment, the number of the positioning grooves 7 may be two, one of the positioning grooves 7 may be rectangular, the other may be semicircular, or both may be rectangular or semicircular, but the two may be different in size.

Through setting up constant head tank 7 on the plug, with the corresponding complex spacer that needs to set up on plug complex socket undoubtedly, through setting up constant head tank 7, can make the warning of grafting position for operating personnel, avoid grafting error to cause contact pin 2 damage or contact failure's risk.

The length of the positioning groove 7 is smaller than that of the plugging part 4, and when the length of the positioning groove 7 is the same as that of the plugging part 4, a gap exists between the sleeved sealing gasket 6 and the positioning groove 7, so that complete sealing cannot be formed on the plugging part 4.

As a supplementary embodiment, the opposite side of casing 3 front end has seted up locating hole 8, and locating hole 8 runs through casing 3 and extension, locating part 9 in the locating hole 8, and locating part 9 select to use the locating bolt, through can carry out locking fixed with the socket that plug is connected with the locating bolt, improves plug socket connection's fastness.

As another embodiment, the outer wall of the rear end of the shell 3 is provided with a step structure, and the cable wrapping the wire core 1 is thinner than the shell 3, so that the shell 3 is convenient to take, visual coordination is better, and meanwhile, the shell 3 with the step structure can save raw materials during production.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
