Abstract

The utility model relates to a plug for electrical devices and a socket structure, in particular to an anti-loose plug and socket structure. The plug comprises a plug body and a grafting body; both sides of the plug body are respectively provided with mutually parallel long slots; the upper end of each long slot is closed, and the lower end is opened; a locking rod is threaded through each long slot; the middle part of each locking rod is hinged in the corresponding long slot through a hinge; the upper end of each locking rod is connected into the long slot through a horizontally arranged flexible element, while the lower end extended out of the plug body is provided with a triangular locking part; the inner end of a pressing body is horizontally connected below the hinge of each locking rod; the outer end of the pressing body is extended out of the plug body; and the socket is provided with a jack corresponding to the plug body, and a lock hole corresponding to the locking part. The utility model mainly solves the technical problems that the existing way of connecting the plug with the socket through a bolt is inconvenient to operate, and the bolt can be easily lost in the use; moreover, the anti-loose plug and socket structure is not only applied to signal plugs and sockets, but also applied to power plugs and sockets.

Description

A kind of anti-loose plugs and sockets structure

Technical field

The utility model relates to the plug and socket structure of electrical equipment, particularly a kind of anti-loose plugs and sockets structure.

Background technology

Present appliance plug and socket kind are a lot, succeed in reaching an agreement from its function often to be divided into attaching plug and socket and Signal plug and socket.The attaching plug significant feature is exactly for electrical equipment provides power supply, and the effect of Signal plug is to provide data message (as: reticle plug provided) for electrical equipment.These plug and sockets mainly comprise in qualitative requirement: the contact of connecting line, insulation safety performance and patch the comfort level of operation and the steadiness of grafting.

Have only Signal plug and socket to have the firm structure of pegging graft in the existing plug and socket, it comprises the extension that is provided with the plug both sides, and this extension is equipped with perforation; The threaded connection hole that on socket, has the perforation of corresponding plug extension; One piece of set bolt is disposed in every pair of perforation respectively, set bolt passes the perforation of plug extension and the threaded connection hole on the socket so that the two is connected and fixed, so just can guarantee the connection stable degree of plug and socket, avoid owing to the insecure situation that causes signal provision to interrupt of pegging graft.But this structure has following shortcoming:

1, by the mode of bolt attachment plug and socket, operate cumbersomely, and bolt is in use lost easily.

2, less attaching plug and the socket of being used for of this structure.

The utility model content

The purpose of this utility model is to provide a kind of anti-loose plugs and sockets structure, mainly solve existing mode by bolt attachment plug and socket, operate cumbersome, and the bolt technical problem of in use losing easily, not only can be applied to Signal plug and socket, can also be applied to attaching plug and socket and.

For addressing the above problem, the utility model is achieved in that

A kind of anti-loose plugs and sockets structure is characterized in that:

This plug comprises plug body and grafting body, and these plug body both sides have the elongated slot that is parallel to each other respectively, and this elongated slot upper end closed, lower end are opened wide; Wear a locking bar in this elongated slot respectively, be hinged in the elongated slot by articulated elements respectively in the middle of the locking bar, this locking bar upper end is connected in the elongated slot by the flexible member of horizontally set respectively, and the position that plug body is extended in the lower end then is provided with leg-of-mutton latch part; Articulated elements below on this locking bar laterally connects a pressing body the inner, and extend outside the plug body this pressing body outer end;

Have on this socket corresponding to the jack of grafting body with corresponding to the lockhole of latch part.

Described anti-loose plugs and sockets structure is characterized in that: be communicated with the spring groove of horizontally set in this plug body with the elongated slot upper end, spring then is arranged in this spring groove.

By technique scheme, the utlity model has following advantage:

1, the utility model can make the two fastening by the structure of snap close and button hole behind plug insertion socket, avoids getting loose.

2, the utility model product is compared with the mode of original bolt, and is easy and simple to handle, laborsaving.

Embodiment

See also Fig. 1, the utility model discloses a kind of anti-loose plugs and sockets structure.As shown in the figure:

This plug 1 comprises plug body 2 and grafting body 3, and these plug body 2 both sides have the

elongated slot

21,22 that is parallel to each other respectively, and these

elongated slot

21,22 upper end closeds, lower end are opened wide; Wear a

locking bar

41,42 in this

elongated slot

21,22 respectively, be hinged in the

elongated slot

21,22 by articulated

elements

51,52 respectively in the middle of the

locking bar

41,42, these

locking bar

41,42 upper ends

flexible member

61,62 by horizontally set respectively are connected (be communicated with the spring groove of horizontally set in this plug body 2 with

elongated slot

21,22 upper ends, spring then is arranged in this spring groove) lower end in the

elongated slot

21,22 and extend the position of plug body 2 and then be provided with leg-of-mutton latch part 411,421;

Articulated elements

51,52 belows on this

locking bar

41,42 laterally connect a

pressing body

71,72 the inners, and extend outside the plug body 2 these

pressing body

71,72 outer ends.

Have on this socket 8 corresponding to the jack 81 of grafting body 3 with corresponding to the lockhole 82 of latch part 411,421.

When plug insertion socket, the latch part 411,421 on the

locking bar

41,42 buckles in the lockhole 82 of socket 8, guarantees that the plug grafting is firm.When plug need be extracted, by pushing

pressing body

71,72 latch part 411,421 is received toward inboard, plug 2 just can have been extracted from socket 8 smoothly like this.

Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
