Son》, its structure is：One end of binding post body sets bolt hole, and middle part is wire insertion groove, binding post body it is another
End is set closely to be connected with the integrally formed waterproof cap of binding post body, the waterproof cap with cable termination；It is described anti-
The internal diameter of water cap is engaged with cross-section of cable diameter.The binding post plays waterproof action by setting waterproof cap, so
This structure needs waterproof cap internal diameter to be engaged with cross-section of cable diameter afterwards, inserts not enter if not being inconsistent slightly and will result in cable
Go or cable and waterproof cap poor sealing and influence waterproof effect, therefore in actual use will to the size of waterproof cap
Ask comparison harsh, be unfavorable for processing and fabricating.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of conjunction simple in construction for the above-mentioned state of the art
Reason, easy to use, the water proof type metal wiring terminal that can effectively prevent moisture from invading.
Technical scheme is used by the utility model solves above-mentioned technical problem：A kind of water proof type metal wiring terminal,
Including flat plate section, changeover portion and the wiring section set gradually, it is characterised in that：The outer end elongation moulding of the wiring section has tubulose
The expanding seal section planted for conductor insulation part, ring offers one or more on the afterbody endoporus wall of expanding seal section
Bar rectangular channel, rectangular channel is interior to be equipped with sealing ring.
As an improvement, the endoporus aperture of the expanding seal section is the 102%~120% of conductor insulation part line footpath, expand
The length of footpath seal section is 0.5~3 times of conductor insulation diameter.
As an improvement, the sealing ring is y-type seal ring.
As an improvement, the wiring section is tubular structure, the endoporus aperture of wiring section is conductor current-carrying part line footpath
102%~110%, the interior hole length of wiring section is 3-6 times of conductor diameter.
Improve again, the electric force compounded grease of water-proof function is scribbled on the endoporus wall of the wiring section.
Improve again, the electric power that water-proof function is scribbled on the endoporus wall and rectangular channel inwall of the expanding seal section is compound
Fat.
Further improve, the changeover portion is the reducing changeover portion in ramp shaped, and changeover portion is solid construction.
Finally, circular arc is asked in the front end of the flat plate section, and the middle part of flat plate section is provided with a circular or special-shaped connecting hole.
Compared with prior art, the utility model has the advantage of：Interior boring ratio and cable are set up in the rear end of wiring section
Or the expanding seal section that outer insulation diameter is slightly larger, and y-type seal ring is set in expanding seal section, the current-carrying part of such conductor is inserted
Enter wiring section, and conductor insulation part is plugged on expanding seal section, and sealed by sealing ring, effectively block entering for rainwater
Leaching, avoid making wire that oxidation and corrosion occur due to moisture intrusion；Further, since the aperture ratio conductor insulation of expanding seal section
Part is slightly larger so that wire insertion is convenient, and is beneficial to processing and fabricating.The utility model is simple and reasonable, it is preferable to have
Waterproof action, it can effectively prevent moisture from entering conductor, delay the oxidation course of conductor, while lift dielectric level and production
Quality, ensure circuit reliability service.
