Description
Technical field
The present invention relates to a kind of rectangle high pressure electrical contact end connector.
Background technology
8 core 12kVDC high pressure electric plug connectors of rectangle are according to the application demand of China's military equipment, are voluntarily developed
Signal transmission apparatus, in system between transmitter and travelling-wave tubes high voltage signal connection and transmission, can be with simultaneous transmission
Multiple higher voltage signal.But existing product is finished low-temperature and low-pressure experiment under 4.4kPa, -55 DEG C of environmental condition and is done again and is situated between
During matter disruptive test, it is easy to there is the phenomenon that dielectric withstanding voltage does not pass through, the analysis found that, be housing with casting glue it
Between due to being bonded breakdown failure phenomenon that is insecure and occurring, so as to cause the failure of product, strengthen between casting glue and housing
Cementability become current rectangle high pressure electrical contact end connector urgent problem to be solved.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of rectangle high pressure electric mortiser with more preferable proof voltage energy
Header connector.
In order to solve the above technical problems, the present invention provides a kind of rectangle high pressure electrical contact end connector, including jack shell
Body, seal cover board, rubber injection sleeve, insertion tube and metal sleeve, plug casing front end face are provided with the grafting groove for coordinating Socket casing, insert
Connecing has several insertion tubes on groove rear wall, there is the internal projecting ring to extend internally in the insertion tube front end, and metal is placed with the middle part of insertion tube
Casing, there is jack in metal sleeve, and rubber injection sleeve is fixedly connected with rear side of plug casing, has seal cover board, encapsulating on rear side of rubber injection sleeve
It is encapsulating region in set, several lead channels is provided with rubber injection sleeve, each lead channels sequentially passes through seal cover board, inserts respectively
Casing stretches into insertion tube；Plug casing, which extends back, inner sleeve, and rubber injection sleeve is extended with the overcoat coordinated with inner sleeve to front side
Ring, fixing pin are stretched into encapsulating region through outer sleeve and inner sleeve；
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 adding 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 more firm, insertion tube root is bonded between engineering plastics
The structure of increase silicone rubber sleeve mainly solves product and works under 4.4kPa, -55 DEG C of low-temperature and low-pressure environmental condition 2h
When carrying out dielectric withstanding voltage experiment, insertion tube root and the phenomenon that casting glue abutting edge is not in breakdown failure, and also product is each
Item performance indicator can be met the requirements.
In addition, the housing, embedding set and the pin that are manufactured using model engineering plastic, not only with 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 present invention, this rectangle high pressure electrical contact end connector is referred to as below
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 security of terminal adapter.
Brief description of the drawings
Fig. 1 is the structure diagram of this plug terminal adapter embodiment.
Fig. 2 is the right view of Fig. 1.
Embodiment
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 insulating materials of the material for 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, the middle part of insertion tube 13 on 12 rear wall of grafting groove
Metal sleeve 14 is placed with, there are the internal projecting ring 13a to extend internally, 14 front end face of metal sleeve and internal projecting ring in each 13 front end of 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
