Description

Connector water-tight structure

Technical field:

The utility model relates to technical field of electric connectors, refers in particular to the connector docking structure.

Background technology:

Electric connector, can realize pegs graft fast uses, and has been widely used at present in the electronic product, especially computer, Communication Equipment etc.At present, electric connector shape and kind are varied, only need get final product during use inserting, quite convenient, however connector commonly used, owing to have defective in the docking structure design, cause plug to insert and not only exist when using slotting not firm, the phenomenon that gets loose easily, and do not have water-proof function, bring inconvenience to use, so improve for being necessary in fact.

The applicant is because the disappearance and the inconvenience of above-mentioned known connector docking structure, the spirit of adhering to the research innovation, keeping on improving, utilize its professional eye and professional knowledge, work out a kind of applied range, meet industrial utilization and can effectively promote the connector docking structure of Butt sealing.

Summary of the invention:

The purpose of this utility model is to provide a kind of butt joint convenient, connects and stablizes, and has the connector water-tight structure of the effect of water-tight.

For achieving the above object, the utility model adopts following technical scheme:

Connector water-tight structure comprises connector plug, is provided with seal in the periphery of plug, takes this, and when plug inserted in the respective socket, the end of seal and socket or inwall formation were sealed and matched.

Seal is an annular, is enclosed within on the plug, and plug offers corresponding annular groove fit seal and installs.

Be compared with the prior art, the utility model is that the periphery at plug is provided with seal, in the time of in plug inserts corresponding socket, seal and socket end or inwall form and are sealed and matched, not only can increase the stability of grafting, and have sealing effectiveness, and reach waterproof and dustproof, improve the connector serviceability.

Embodiment:

Understand for the juror can be had purpose, feature and the function of the utility model further, lift preferred embodiment now and cooperate graphic being described in detail as follows:

At first seeing also Fig. 1, shown in Figure 2, is the structural representation of the preferred embodiment of the utility model, and the utility model is relevant connector water-tight structure, comprise a plug 10, plug is implanted into respective terminal, is used for electrically connecting butt joint, realizes the signal transmission.Periphery at plug 10 is provided with seal 20, takes this, and when plug 10 inserted in the respective socket, seal 20 was sealed and matched with the end or the inwall formation of socket.

Seal 20 is an annular, adopts the colloidal materials moulding, is enclosed within on the plug 10, and plug 10 offers corresponding annular groove 11 fit seal 20 and installs.Seal 20 outer peripheral faces are a little more than the plug periphery, and end or the inwall formation of satisfying seal 20 and socket are sealed and matched.

Shown in Fig. 3,4,5,6, during enforcement, the female seat 30 of docking with plug is formed with a socket 31, and socket 31 shapes are the same with plug, are prolate shape, have the fool proof function; Be provided with tongue piece 32 in the socket 31, tongue piece 32 is provided with respective terminal, for use in the terminal in the electrical banjo, is provided with hanging platform 33 in the periphery of female seat 30, and hanging platform 33 is the evagination form, with female seat 30 one-body molded making.For cooperating hanging platform 33 work, at the outside of plug extended configuration hook 12 is arranged, with the hanging platform 33 that articulates female seat 30, realize axial limiting.

From shown in Fig. 3,4,5 as can be known, the hanging platform 33 of female seat 30 is symmetrical set, corresponding plug hook 12 also is symmetrical set, hook 12 is molded on the left and right sides alar part 13, and alar part 13 is crossed out by the plug rear end, is the T font, form press sections 14 with the hook 12 relative other ends, like this, can realize pressing press section 14 and drive hook 12 outer opening, to reach the action of triping.

Group is established when implementing, and plug 10 axially docks with female seat, and in the socket 31 of insertion female seat, and the tongue piece 32 in the socket is complied with in insertion plug the corresponding interface, makes the respective terminal in both form electric connection, realizes that signal transmits.20 of the seals of plug periphery are followed and are inserted in the socket 31, and are sealed and matched (shown in Fig. 5,6) with the formation of socket inwall, not only can increase the stability of grafting, and have sealing effectiveness, reach waterproof and dustproof, improve the connector serviceability.When plug 10 was pegged graft, the hook 12 in plug 10 outsides was also taken advantage of a situation on the hanging platform 33 that is buckled in the female seat periphery, realizes axial restraint, prevents plug 10 and female seat axial separation, is connected firmly.

In the time of need pulling the plug out of the socket, inwardly press press section 14, utilize the structural of alar part 13, press section 14 inside pressures are then linked up with 12 outer sticking up and are opened, and break away from hanging platform 33 with this, reach the action of triping, with pulling the plug out of the socket.

Certainly, more than diagram is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so every principle according to the utility model is done the equivalence variation or modified, and all should be covered by in the protection range of the present utility model.
