Embodiment
The utility model is described in detail presently in connection with accompanying drawing.This figure is simplified schematic diagram, only in a schematic way
Illustrate basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.
Fig. 1, Fig. 2 and Fig. 3 are referred to, the utility model provides a kind of connector, and the connector includes circuit board 1 and connected
The first injection molding body 3 for connect wire harness 2 on the circuit card 1, forming outside circuit board 1 by Shooting Technique, it is set in the first note
Metal shell 4 outside plastomer 3, the second injection molding body 5 formed by Shooting Technique outside metal shell 4 and pass through injection
The 3rd injection molding body 6 that technique is formed outside the second injection molding body 5.
Referring to Fig. 2, in present embodiment, wire harness 2 includes the first wire 21, the second wire 22 and privates 23, can
To understand ground, in other unshowned embodiments, wire can also only have one or two or more than three, user Ke Gen
According to needing voluntarily to set.In addition, each wire is connected on the circuit card 1 by welding manner.
Fig. 3 and Fig. 4 are referred to, when connector assembles, wire harness 2 is connected on the circuit card 1, for the first time the first note of injection
Plastomer 3, which is arranged on outside circuit board 1, prevents water from entering circuit board 1 and wire harness 2, and the injected plastics material of the first injection molding body 3 is using viscosity
Good, high temperature resistant, anti-vibration, corrosion resistant PUR, make wire harness 2, the injection molding body 3 of circuit board 1 and first be closely linked, and prevent
Only wire harness 2 or circuit board 1 come off.
Referring to Fig. 4, metal shell 4 is set in the outside of the first injection molding body 3, and then by the first injection molding body 3 and circuit
Plate 1 wraps up, and metal shell 4 can prevent electromagnetic interference and antidetonation.Under metal shell 4 includes upper lid 41 and engaged with upper lid 41
Lid 42, in use, upper lid 41 and lower cover 42 are fixed, compared to the work of the soldering again of the outside copper-clad paper tinsel of circuit board 1 before
