The other end is connected with a black rubber core, and a terminal is provided under the black rubber core, and a PIN pin is provided inside the PCB contact piece, and an insulating device is provided under the PIN pin.

Further, rivets are provided on both sides of the PCB contact piece, and the iron shell is fixedly connected to the black rubber core through rivets.

Further, elastic iron sheets are provided on both sides of the black rubber core.

Further, the harpoon pin is an upright SMT short-body harpoon pin, and the surface of the PCB contact piece is provided with a gold-plated layer.

Further, the stainless steel shell is integrally plated with nickel, and the insulating device is epoxy resin fiberglass.

Compared with the prior art, the utility model has the following beneficial effects: this kind of straight piece harpoon can prevent rust by using nickel plating on the surface of the stainless steel shell, and it can be highly polished. The prongs and fixed ports are convenient for connecting the straight piece harpoon connector to the device, improving work efficiency, and using the contact of the PCB contact to achieve conduction, because the elastic iron pieces on both sides of the black rubber core are opposite to the straight piece harpoon It plays a certain role of conduction and fastening, and realizes data transmission by using the contact of the PIN pin set on the surface of the PCB contact piece. At the same time, combined with the insulation device set under the PIN pin, it effectively prevents the leakage of electricity and prevents accidents. By using the combination of short terminals and long terminals, the amount of interference and the position of the sticking are different, and there will be no problem that the long terminal interference has been damaged by the short terminal, so that each terminal can be well interfered and fixed inside the black rubber core. , will not spring back, and the long terminal can prevent it from sinking, so that the position of each row of terminals is well resolved, and the use of rivets plays a fixed role to ensure the position and quality of the product's solder feet. The utility model structure Simple, novel design, easy to connect, improve work efficiency, ensure terminal positioning without sinking, ensure terminal quality, prevent rust, can be highly polished, effectively prevent electricity leakage, prevent accidents, and have conductive and fastening functions , Simple operation, safe and reliable.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

As shown in Figures 1-4, a straight piece harpoon includes a stainless steel shell 1, a PCB contact 2 and a harpoon foot 4, the surface of the stainless steel shell 1 is provided with a PCB contact 2, and the bottom of the stainless steel shell 1 An iron shell 7 is provided, and a black rubber core 13 is provided inside the iron shell 7. A short terminal 8 is provided inside the black rubber core 13, and a long terminal 9 is provided on one side of the short terminal 8. The stainless steel shell 1 One side is provided with a fixed port 5, and one side of the fixed port 5 is provided with a harpoon foot 4 and the other end of the harpoon foot 4 is connected to a black rubber core 13, and a terminal 6 is provided below the black rubber core 13, and the A PIN pin 12 is provided inside the PCB contact piece 2 , and an insulating device 11 is provided below the PIN pin 12 .

Wherein, the two sides of the PCB contact 2 are provided with rivets 3 , and the iron shell 7 is fixedly connected with the black rubber core 13 through the rivets 3 .

Wherein, elastic iron sheets 10 are arranged on both sides of the black rubber core 13 .
