Multiple higher voltage signal.But existing product is finished low-temperature and low-pressure experiment at 4.4kPa, -55 DEG C of environmental condition and is done again and is situated between
When matter disruptive test, it is easy to occur dielectric withstanding voltage not by the phenomenon that, the analysis found that, be shell with casting glue it
Between due to being bonded breakdown failure phenomenon that is insecure and occurring, to cause the failure of product, enhance between casting glue and shell
Cementability become current rectangle high pressure electrical contact end connector urgent problem to be solved.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of rectangle high pressures with better proof voltage energy
Electrical contact end connector.
In order to solve the above technical problems, the utility model provides a kind of rectangle high pressure electrical contact end connector, including insert
Casing, seal cover board, rubber injection sleeve, insertion tube and metal sleeve, the grafting that plug casing front end face is provided with cooperation Socket casing are recessed
Slot has on grafting groove rear wall several insertion tubes, the insertion tube front end to have the internal projecting ring to extend internally, be placed in the middle part of insertion tube
Metal sleeve has jack in metal sleeve, and rubber injection sleeve is fixedly connected on rear side of plug casing, has seal cover board on rear side of rubber injection sleeve,
It is encapsulating region in rubber injection sleeve, is provided with several wire channels in rubber injection sleeve, each wire channel sequentially passes through sealing cover respectively
Plate, plug casing stretch into insertion tube；Plug casing, which extends back, inner sleeve, and rubber injection sleeve is extended with to front side to be coordinated with inner sleeve
Outer sleeve, fixing pin are stretched into through outer sleeve and inner sleeve in encapsulating region；
Plug casing rear end face is provided with encapsulating groove, and the insertion tube, which extends back, insertion tube root, and at insertion tube root
In in the encapsulating groove of plug casing, insertion tube root outer wall is set with silicone rubber sleeve, between insertion tube root and silicone rubber sleeve
Fixation is closely bonded by silicon rubber.
After such structure, due to increasing silicone rubber sleeve, and silicon rubber first carried out with insertion tube root it is be bonded,
If there is bad phenomenon is bonded, it can observe by the naked eye out, directly screen out because of insertion tube root and silicone rubber sleeve
Between be bonded it is insecure caused by failure, since silicone rubber sleeve tube material is silicon rubber, and casting glue is also silastic material, this
It is bonded between two kinds of identical materials and more direct than silicon rubber is bonded more secured, insertion tube root between engineering plastics
The structure for increasing silicone rubber sleeve mainly solves product and works at 4.4kPa, -55 DEG C of low-temperature and low-pressure environmental condition 2h
When carrying out dielectric withstanding voltage experiment, insertion tube root is not in the phenomenon that breakdown is failed with casting glue abutting edge, and product is each
Item performance indicator can be met the requirements.
In addition, using model engineering plastic manufacture shell, embedding set and pin, not only have good mechanical strength and
Dimensional stability, and it is light-weight, environmental resistance is good, dieletric strength is high.
For the clearer technology contents for understanding the utility model, below by the connector letter of this rectangle high pressure electrical contact end
Referred to as this plug terminal adapter.
The plug casing outer wall of this plug terminal adapter is equipped with flange；After such structure, flange can facilitate with
External equipment coordinates, and saves installation space.
The material of the plug casing of this plug terminal adapter is insulating materials；After such structure, this plug is improved
The safety of terminal adapter.
Description of the drawings
Fig. 1 is the structural schematic diagram of this plug terminal adapter embodiment.
Fig. 2 is the right view of Fig. 1.
Specific implementation mode
As shown in Fig. 1 to 2
This plug terminal adapter includes plug casing 11, seal cover board 16, rubber injection sleeve 15, insertion tube 13 and metal sleeve 14.
Plug casing 11 uses material for the insulating materials of diallyl isophthalate, and 11 front end face of plug casing is provided with
Coordinate the grafting groove 12 at 11 rear portion of Socket casing, there is eight hard insertion tubes 13,13 middle part of insertion tube on 12 rear wall of grafting groove
It is placed with metal sleeve 14, there are the internal projecting ring 13a to extend internally, 14 front end face of metal sleeve and internal projecting ring in 13 front end of each insertion tube
The rear end face of 13a coordinates, and limits the position of metal sleeve 14, metal sleeve 14 is using the copper alloy with favorable elasticity, surface
Plating is hard golden, has jack in metal sleeve 14.
Plug casing 11, which extends back, inner sleeve 11a, and the encapsulating groove (figure of plug casing 11 is formed in inner sleeve 11a
