Polyamide is made, and that is to say the interior injection coating member 20 by the integral part of molten polyamide cure.Preferably, in order to carry
Sealing property is risen, the inner surface of the interior injection coating member 20 coheres with the metal connecting terminal 10 to be integrally provided.As
It is preferred that the outer surface of the interior injection coating member 20 is cohered with the shell body 30 and is integrally provided.In the present embodiment, it is described
The inner surface of interior injection coating member 20, outer surface are cohered integratedly with the metal connecting terminal 10 and the shell body 30 respectively
Set.The interior injection coating member 20 coheres ability with metal connecting terminal 10 with good.The interior injection coating member 20
With low or equal in the fusing point of the shell body 30, (i.e. described shell body 30 is with molten higher than the interior injection coating member 20
Point), cohere energy between the interior injection coating member 20 and the metal connecting terminal 10, the shell body 30 so as to be lifted
Power.In order to further enhance the sealing property to the metal connecting terminal 10, the interior injection coating member 20 and the metal
The cohesion of connection terminal 10 is more than the shell body 30 and the cohesion of the metal connecting terminal 10.It that is to say, it is described outer
Housing 30 from it is described it is interior injection coating member 20 extend to connection terminal 10 described in covering part and with the metal connecting terminal 10
During sealed connection, the shell body 30 by external force drive and cause the shell body 30 have with it is described it is interior injection coating member 20 and
During 10 separation trend of metal connecting terminal, the shell body 30 will not cause interior injection coating member 20 to be connected with the metal
Terminal 10 is separated, and the performances such as the shell body 30 are changed so as to obtain.It is to be appreciated that the corresponding shell body 30,
As long as the material selection of the interior injection coating member 20 and the connection terminal 10 meets above-mentioned cohesion requirement.
Please continue to refer to Fig. 4 to Fig. 7, interior injection coating member 20 ground is set described in the environmental sealing of shell body 30.It is described
As long as shell body 30 can be realized to the interior injection coating member 20 ground sealing, so as to enter to advance to the metal connecting terminal 10
One step seals.In order to strengthen, machinery is firm and sealing property, the shell body 30 are integrated through injection molding part.Specifically, it is described
Shell body 30 is embedded injection (insert molding) one with the metal connecting terminal 10, the interior injection coating member 20
Body part.Embedded injection, also referred to as insert injection moulding.In the present embodiment, the metal connecting terminal 10 and the interior note
Modeling coating member 20 is inserts.The metal connecting terminal 10, interior injection coating member 20 insertion are arranged on the shell body 30
It is interior.It that is to say, the metal connecting terminal 10, the interior injection coating member 20 are previously positioned in mould, then pass through injection
The shell body 30 is made.
In order to seal the sealing 11 of the metal connecting terminal 10, the shell body 30 has holding parts 31.It is described solid
Interior injection coating member 20 ground described in the environmental sealing of portion 31 is held to set.It that is to say, when being molded completion, the metal connecting terminal
10th, interior injection coating member 20 insertion is arranged in the holding parts 31.In the present embodiment, the holding parts 31 are arranged on
On following shell bodies 33.Further, in order to lift the sealing protection performance to the sealing 11, the one of the holding parts 31
End or both ends protrude from the ground of shell body 33 along the length direction parallel to the metal connecting terminal 10 and set.In the present embodiment
In, the both ends of the holding parts 31 protrude from the setting of the ground of shell body 33.The holding parts 31 can not only strengthen to the gold
Belong to the firm supporting role of connection terminal 10, additionally it is possible to which the interior injection coating member 20 is firmly attached to the sealing 11
On.
In order to consolidate the support sealing 11, the shell body 30 also includes shell body 33.The shell body 33 is along institute
The circumferentially extending of metal connecting terminal 10 is stated in loop-like, so as to for the sealing 31 provide more firm balancedly support and
The holding parts 31 are enabled closely to wrap up the interior injection coating member 20.The shell body 33 is arranged on the holding parts
Extend continuously to set on 31 and along the length direction of the metal connecting terminal 10.The shell body 33 surrounds cavity volume.It is described
Cavity volume is used for accommodating at least partly described connecting portion 12.
In order to strengthen the wear-resistant of shell body 30, resistance to elevated temperatures and improve mechanical strength, the shell body 30 by
Polyhexamethylene adipamide (Polyhexamethylene Adipamide) is made.Polyhexamethylene adipamide, also known as nylon66 fiber, it is
A kind of thermoplastic resin.It that is to say, the capsul 30 is formed integrally part by melting polyhexamethylene adipamide.Preferably, it is described
Shell body 30 has the fusing point higher than the interior injection coating member 20, and the resistance to of coating member 20 is internally molded so as to be not only convenient for being lifted
Thermal protective performance, so that interior injection coating member 20 enhancing and the shell body 30, the metal connecting terminal 10
Between stable bond performance.
