The present utility model provides an airtight and watertight multi-core sealing assembly which is reasonable in structure and can solve defects of the prior glass sintering sealing assembly. The assembly is characterized in that the sealing assembly is composed of an epoxy resin injection molding body (1) and a pin contact piece (2), in the sealing assembly, a die opening method is adopted, epoxy resin materials are injected and molded through high temperature and high pressure, and the epoxy resin injection molding body is tightly and integrally combined with the pin contact piece (2) during the injection molding process. . By adopting the sealing assembly, the stability of electrical performance of a connector can be guarantee firstly, end face vertical water pressure and oil pressure resistant requirements can be satisfied, the intensity is large, the processing period is short, and the mechanical performance and the electrical performance are stable and reliable.
Description
Technical field
The utility model relates to watertight (airtight) electric connector field.
Technical background
Traditional watertight (airtight) connector adopts the mode of glass sintering to realize the function of the vertical water pressure resistance of connector (air pressure) usually.
In conjunction with referring to Fig. 1 (a), Fig. 1 (b), Fig. 1 (c), Fig. 1 (d); Among the figure, A1 is a connector shell, and A2 is a seal glass, and A3 is a contact pin contacting piece, and A4 is a sintered ring.
Glass sintering spare structure suitable has its limitation: the one, and glass sintering spare is difficult to realize the sintering of jack contact, can only adopt contact pin contacting piece to carry out sintering; The 2nd, because structure is limit, the spacing between glass sintering spare contact must keep certain numerical value, and it is more to satisfy the core number, the black box requirement that arranging density is bigger.Because these structural restrictions cause the scope of application of glass sintering spare and occasion to be limited to very much.
And glass sintering itself exists many defectives and hidden danger: the vitreum fragility of glass sintering is bigger, and sintering is difficult to reprocess after accomplishing; The glass exposure of some trade mark easy moisture absorption in air the time influences electric property; The sintered products consistency is relatively poor, can not satisfy large batch of production demand; And vitreum is different with the expansion rate of expanding with heat and contract with cold of other metal partss of black box, under rugged environment, gaps easily and causes decline airtight, watertightness performance; On sintered components, sign inconvenience; Structure is single, can not satisfy the demand of various environment or unconventional mounting structure.
The utility model content
The utility model technical problem to be solved is, to the deficiency of prior art, a kind of airtight and watertight multicore black box is provided, and is rational in infrastructure, can solve some drawbacks that traditional glass sintering black box exists.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of airtight and watertight multicore black box is characterized in that: said black box is made up of epoxy resin injection molding body 1 and contact pin contacting piece 2; Said black box is the mode that adopts die sinking, with epoxide resin material through the HTHP injection molded, in the process of injection moulding with the contact pin contacting piece 2 formation one of combining closely.
Said epoxy resin injection molding body 1 be provided with step surface 11 be used for connector in gland nut cooperate and realize axial location; Also be provided with on the said epoxy resin injection molding body 1 positioning spline 12 be used for connector in the positioning key realization radial location that matches.
The utility model can bring following beneficial effect:
The utility model can solve the problem of the vertical water pressure resistance oil pressure of connector ends, has improved the intensity of black box, can reprocess after the completion; The insulating material stable performance, nonhygroscopic, guarantee that electric property is stable; Homogeneity of product is high, can satisfy large batch of production demand; Do not receive the restriction of dimensional structure, it is more to satisfy the core number, the black box requirement that arranging density is bigger; The epoxy injected plastics material can be when injection molded, directly with needed sign once-forming on assembly surface; Structure can arbitrarily change according to the difference of installing and using environment.In addition, the utility model can make the black box modularization, forms process line, improves the processing efficient of connector black box greatly.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Like Fig. 2, shown in Figure 3,1 is the epoxy resin injection molding body among the figure, and 2 is contact pin contacting piece, and 11 is step surface, and 12 is positioning spline.
Present embodiment is the vitals in certain watertight connector, vertical water pressure resistance of this part requirement end face and oil pressure 4.4Mpa.
This modular construction is made up of the two large divisions, comprises epoxy resin injection molding body 1 and contact pin contacting piece 2.
(1) mentality of designing
Because the applied connector contact core of this product number is more, arrange comparatively closely, and the order demand is bigger, so the structure of employing epoxy injection moulding black box.The sealing assembly at first can guarantee the stable of connector electric property, satisfies the requirement of vertical water pressure resistance of end face and oil pressure simultaneously, and intensity is big, and the process-cycle is short, and mechanical performance and electric property are reliable and stable.
(2) structural design
Adopt the mode of die sinking, with the contact pin contacting piece 2 of brass material, again with epoxide resin material through the HTHP injection molded; With the contact pin contacting piece 2 formation one of combining closely; Make whole black box modularization,, improved the convenience of connector fitting operation to be easy to installation and assembling.
Referring to Fig. 4.
Claims (2)
1. airtight and watertight multicore black box, it is characterized in that: said black box is made up of epoxy resin injection molding body (1) and contact pin contacting piece (2); Said black box is the mode that adopts die sinking, with epoxide resin material through the HTHP injection molded, in the process of injection moulding with contact pin contacting piece (2) the formation one of combining closely.
2. according to claim 1 described a kind of airtight and watertight multicore black box, it is characterized in that: said epoxy resin injection molding body (1) be provided with step surface (11) be used for connector in gland nut cooperates the realization axial location; Also be provided with on the said epoxy resin injection molding body (1) positioning spline (12) be used for connector in the positioning key realization radial location that matches.
