Abstract

The utility model discloses a plug and a socket. The plug and the socket comprises a rubber plug casing, a plug, a rubber socket casing and a socket, the rubber plug casing is sleeved on the plug and connected with the plug, the rubber socket casing is sleeved on the socket and connected with the socket, an annular groove and an annular limiting stand are arranged on the peripheral wall of the left portion of the rubber plug casing, an inner cavity is mounted on the right of the rubber socket casing, the left portion of the rubber plug casing is located in the inner cavity, an annular boss matched with the annular groove is arranged on the circumference wall of the inner cavity, and the right end face of the rubber socket casing is tightly attached to the side wall of the left end of the annular limiting stand. The plug and the socket have the advantages that the relative displacement between the plug and the socket can be effectively prevented, and the dust prevention effect is good.

Description

Plugs and sockets

Technical field

The utility model relates to a kind of circuit connector spare, particularly a kind of plugs and sockets.

Background technology

Plugs and sockets is electrical equipment requisite circuit connector spare when being connected with power supply, and along with the progressively enhancing of Electrical Safety consciousness, people are also more and more higher to the requirement of plugs and sockets.existing plugs and sockets, being connected and fixed between its plug and socket is mostly just to rely on the latch reed to the clamping of latch, therefore, (need to drag plugs and sockets as people because using) in the plugs and sockets motion process, between the plug and socket of originally mutually being close to, relative displacement might occur, thereby cause producing between plug and socket the gap, at this moment, air, ground dust granules will enter into this gap, and be deposited in gradually latch, latch reed etc. is located, thereby very easily cause between latch or creepage distance deficiency between the latch reed, affect the safe handling of plugs and sockets.

The utility model content

The technical problems to be solved in the utility model is that a kind of can effectively prevent from occuring between plug and socket relative displacement, the plugs and sockets of good dustproof effect are provided.

for solving the problems of the technologies described above, the utility model provides a kind of plugs and sockets of following structure: comprise the rubber plug shell, plug, rubber socket shell and socket, the rubber plug casing is on plug, and be connected with plug, the rubber socket casing is on socket, and be connected with socket, wherein, rubber plug shell left part periphery wall is provided with annular groove and annular stop platform, rubber socket shell right part is provided with inner chamber, rubber plug shell left part is positioned at inner chamber, the inner chamber perisporium is provided with the annular boss that matches with annular groove, annular stop platform left end side-walls is close in rubber socket shell right side.

after adopting said structure, compared with prior art, the utlity model has following advantage: when socket and plug connects and mutually is close to, rubber plug shell left part inner chamber perisporium will be enclosed within on rubber plug shell left part periphery wall, and be located at the annular boss on the inner chamber perisporium and be located at annular groove on rubber plug shell left part periphery wall mutually under the fastening effect, the socket that interconnects and be close together and plug will can not produce relative displacement in the plugs and sockets motion process, therefore having guaranteed effectively that rubber socket shell right side can remain mutually with annular stop platform left end sidewall is close to, make air, ground dust granules can't enter in plugs and sockets, thereby played good dust-proof effect, effectively guaranteed the safe handling of the utility model plugs and sockets.

Fig. 2 is the axial sectional structure schematic diagram of the utility model plugs and sockets.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model plugs and sockets is described in further detail.

as depicted in figs. 1 and 2, in this embodiment, the utility model plugs and sockets comprises rubber plug shell 1, plug 2, rubber socket shell 3 and socket 4, rubber plug shell 1 is enclosed within on plug 2, and be fixedly connected with plug 2 by screw, rubber socket shell 3 is enclosed within on socket 4, and be fixedly connected with socket 4 by screw, rubber plug shell 1 left part periphery wall is provided with annular groove 5 and annular stop platform 6, rubber socket shell 3 right parts are provided with inner chamber 7, rubber plug shell 1 left part is positioned at inner chamber 7, inner chamber 7 perisporiums are provided with the annular boss 8 that matches with annular groove 5, annular stop platform 6 left end side-walls are close in rubber socket shell 3 right sides.

Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection range of the utility model claims.
