Description
Technical field
The utility model belongs to Signal transmissions wire connection structure, specifically, relates to a kind of waterproof wiring joint.
Background technology
Situation that existing holding wire connects (holding wire of water meter that line is checked meter now strictly according to the facts connects), exist more wiring loaded down with trivial details, take a lot of work, time-consuming and connection joint is non-watertight, waterproof effect is not good, the problems such as wiring place loose contact.
Chinese patent CN 202662879 U discloses a kind of waterproof wiring joint, belongs to holding wire syndeton.This utility model comprises wiring male, wiring female, wiring nut, sealing ring, wiring male establishes contact pin, wiring female establishes copper sleeve, the male outer coating of wiring male, the female outer coating of wiring female sets up separately and the external screw thread that wiring nut thread coordinates and the axially loaded portion corresponding with axial tightening portion.
But the structure of this device is too complicated and huge, water proofing property and steadiness are also inadequate, easily damage.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art part, the purpose of this utility model is to provide the DB9 waterproof cable assembly that a kind of structure is simple, air-tightness is strong, to overcome defect of the prior art.
To achieve these goals, the utility model provides a kind of DB9 waterproof cable assembly, described DB9 waterproof cable assembly is provided with a sleeve pipe, cable is arranged with in described sleeve pipe, described cable is electrically connected with pin head, the injection moulding internal mold be made up of rubber is arranged with outside described sleeve pipe, the injection moulding external mold be made up of PVC is arranged with outside described injection moulding internal mold, the top of described sleeve pipe is provided with a panel screw, described panel screw level is arranged among injection moulding internal mold and injection moulding external mold, one end of described panel screw is socketed with inner support, the side of described inner support is connected with metal shell, described metal shell and described pin head insulate.
As further illustrating DB9 waterproof cable assembly described in the utility model, preferably, described metal shell is electrically connected with the screen of described cable.
As further illustrating DB9 waterproof cable assembly described in the utility model, preferably, described injection moulding external mold is provided with a kink, and described injection moulding internal mold is covered in the inwall of whole kink.
As can be seen here, the DB9 waterproof cable assembly that the utility model provides, due to the setting of injection moulding internal mold and injection moulding external mold, such that structure of the present utility model is simple, good waterproof performance, and can reduce small product size.
Accompanying drawing explanation
Fig. 1 is the cutaway view of DB9 waterproof cable assembly of the present utility model;
Fig. 2 is the cutaway view of another embodiment of DB9 waterproof cable assembly of the present utility model;
Fig. 3 is the structural representation of the pin head of DB9 waterproof cable assembly of the present utility model.
Description of reference numerals is as follows:
Sleeve pipe 1, cable 11, pin 2, inner support 3, metal shell 4, injection moulding external mold 5, injection moulding internal mold 6, panel screw 7, kink 8.
Embodiment
Structure of the present utility model, feature and other objects is understood further in order to enable auditor, preferred embodiment appended by now combining is accompanied by accompanying drawing and is described in detail as follows, embodiment illustrated by this accompanying drawing is only for illustration of the technical solution of the utility model, and non-limiting the utility model.
First, please refer to Fig. 1, Fig. 1 is the cutaway view of DB9 waterproof cable assembly of the present utility model.As shown in Figure 1, the DB9 waterproof cable assembly that the utility model provides is provided with a sleeve pipe 1, cable 11 is arranged with in sleeve pipe 1, cable 11 is electrically connected with pin 2, the injection moulding internal mold 6 be made up of rubber is arranged with outside sleeve pipe 1, the injection moulding external mold 5 be made up of PVC is arranged with outside injection moulding internal mold 6, the top of sleeve pipe 1 is provided with a panel screw 7, panel screw 7 level is arranged among injection moulding internal mold 6 and injection moulding external mold 5, one end of panel screw 7 is socketed with inner support 3, inner support 3 is connected with metal shell 4, metal shell 4 and pin 2 insulate.
In addition, metal shell 4 of the present utility model is electrically connected with the screen of cable 11, thus, not only makes ground connection more simple, but also reduces small product size.
As shown in Figure 2, injection moulding external mold 5 is provided with a kink 8, and injection moulding internal mold 6 is covered in whole kink 8 inwall, effectively can avoid the cable that fractures thus, makes the waterproof cable assembly of this structure can adapt to the narrower and small or not easy-operating environment in space.
As can be seen here, the DB9 waterproof cable assembly that the utility model provides, due to the setting of injection moulding internal mold and injection moulding external mold, such that structure of the present utility model is simple, good waterproof performance, and can reduce small product size.
It is to be understood that, above-mentioned utility model content and embodiment be intended to prove the utility model the practical application of technical scheme is provided, should not be construed as the restriction to the utility model protection range.Those skilled in the art in spirit of the present utility model and principle, when doing various amendment, equivalent replace or improve.Protection range of the present utility model is as the criterion with appended claims.
