Description

A kind of closed type connector

Technical field

The utility model belongs to connector technique field, and in particular to a kind of automobile closed type connector.

Background technique

Connector is by whether waterproof and dustproof can be divided into closed type connector and non-tight type connector.Wherein closed type connects Device is connect because it can realize waterproof and dustproof function, therefore suitable for automobile engine nacelle, chassis etc. to connector waterproof and dustproof The more demanding position of energy.Existing closed type connector is typically all in-line structure, is easy to appear the situation for loosening and mispluging, And sealing ring is set at female terminal sheath and plug terminal sheath cooperation, since sealing ring is assemblied in female terminal in use Between the parallel mating surface of the direction of insertion of sheath and plug terminal sheath and machinery positioning can not be realized with sheath, in socket end Easily there is the improper deformation of sealing ring in sub- sheath and plug terminal sheath swapping process（In the deformation of direction of insertion）, transposition, The case where falling off, so as to cause seal failure.

Summary of the invention

The utility model provides a kind of closed type connector, unstable for solving existing closed type connector connection, holds Easily there is the technical problem mispluged and sealing performance is poor.

In order to solve the above technical problems, technical solution used by the utility model is as follows：

A kind of closed type connector, including plug boot and socket jacket, are provided with plug terminal in plug boot, insert It is provided with female terminal in seat sheath, is symmetrically arranged with location hole in the lower part of plug boot, and symmetrical in plug boot inner wall It is provided with sliding groove, sliding groove is located under location hole and communicates with the inner vertical of location hole；It is symmetrical in the outer wall of socket jacket It is provided with holding tank, a resilient clip is mounted in each holding tank, the upper end of resilient clip is provided with fixture block, fixture block It is matched with location hole.

The position being in contact in plug boot with socket jacket is provided with perpendicular with plug terminals and socket terminals Sealing plate is provided with the relief hole plugged for plug terminals and socket terminals on sealing plate.

The present invention links together plug boot and socket jacket in such a way that resilient clip and location hole match, And in the sliding groove of the inner wall of plug boot setting, fixture block can be made to slide inside it, it is ensured that socket jacket can be correctly inserted into slotting In end protective cover, the generation for mispluging situation is prevented.Moreover, during insertion, resilient clip can be by the extruding of plug boot It is inside contracted toward holding tank dynamic, it is ensured that socket jacket can be inserted into plug boot.Moreover, because sealing plate is fixedly disposed at plug retaining In set, in grafting, plug terminals and socket terminals realize grafting by relief hole, dramatically reduce and expose area, energy Improve sealing performance to a certain extent, and sealing plate be it is perpendicular with the plugging direction of plug terminals and socket terminals, keep away Phenomena such as having exempted from the deformation, transposition of sealing ring in plug boot and socket jacket swapping process, having fallen off, further improves close Seal effect.

Detailed description of the invention

In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with It obtains other drawings based on these drawings.

Fig. 1 is the assembling schematic diagram of the utility model.

Fig. 2 is the structural schematic diagram of the utility model plug boot.

Fig. 3 is the structural schematic diagram of the utility model socket jacket.

Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other under that premise of not paying creative labor Embodiment shall fall within the protection scope of the present invention.

As shown in Figure 1-3, a kind of closed type connector, including plug boot 1 and socket jacket 2, it is set in plug boot It is equipped with plug terminal, is provided with female terminal in socket jacket 2, is symmetrically arranged with location hole 3 in the lower part of plug boot 1, and It is symmetrically arranged with sliding groove 4 in 1 inner wall of plug boot, sliding groove 4 is located under location hole 3 and the inner vertical phase with location hole 3 It is logical；It is symmetrically arranged with holding tank 5 in the outer wall of socket jacket 2, a resilient clip 6, bullet are mounted in each holding tank 5 The upper end of property clamp 6 is provided with fixture block 7, and fixture block 7 is matched with location hole 3.

Preferably, in order to improve the sealing performance of connector, the position being in contact in plug boot 1 with socket jacket 2 It is provided with the sealing plate 8 perpendicular with plug terminals and socket terminals, is provided on sealing plate 8 for plug terminals and socket terminals The relief hole 9 plugged.

In insertion, first it is retracted into it in holding tank resilient clip pressing, socket jacket is then inserted into plug retaining In set, resilient clip makes fixture block be adjacent to sliding groove under the action of own resilient, exerts a force to socket jacket, is inserting socket jacket Sliding in end protective cover, when fixture block slides into position of positioning hole, fixture block enters positioning hole and connects plug boot and socket jacket It is connected together.When needing to remove, fixture block is pressed, fixture block is detached from from positioning hole and enters in sliding groove, then pull downward on Socket jacket separates plug boot and socket jacket.

The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
