[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0017] like Figure 1 and Figure 2 The diagram shows a mining cable head structure, including a male plug 1 and a female plug 2. The male plug 1 and female plug 2 are respectively connected and installed on two devices, and are plugged into each other. After the male plug 1 and female plug 2 are plugged in, they are clamped and secured by the two ends of a U-shaped clip 3 passing through their connection points. The male plug 1 is provided with multiple copper male pins 11, and the copper male pins 11 are assembled and pressed together with plastic terminals and installed in the mounting holes on the male plug 1. The female plug 2 is provided with multiple copper female pins 21, and the copper female pins 21 are assembled and pressed together with plastic terminals and installed in the mounting holes on the female plug 2. The copper female pins 21 are correspondingly connected and engaged with the copper male pins 11. A cable 4 is connected to the female plug 2, and the end of the cable 4 is soldered to the copper female pins 21.
[0018] In a preferred embodiment, an O-ring is provided at the connection between the male plug 1 and the male copper pin 11.
[0019] In a preferred embodiment, an O-ring is provided at the connection between the female plug 2 and the copper pin 21.
[0020] In a preferred embodiment, a cable locking sleeve 41 is rotatably sleeved on the cable 4, and after the cable locking sleeve 41 is locked by rotational pressure, it is fixed to the female plug 2 by injection molding with a plastic sleeve 42.
[0021] This utility model discloses a mining cable head structure. The newly manufactured cable head's male and female plugs rely on a keyway structure to prevent incorrect insertion. The male and female copper pins are clamped by seven-hole plastic terminals to prevent short circuits. The keyway structure at the interface between the plastic terminals and the male and female plugs also prevents incorrect installation. A U-shaped ring seal at the joint of the male and female plugs prevents liquid from entering. The U-shaped clip connection between the male and female plugs is stable, reliable, and easy to insert and remove.
[0022] Specifically, for male plug 1 assembly: the plastic terminal assembles and presses the seven copper pins male 11 into one piece, inserts them into the hole of male plug 1, inserts a retaining ring into one end of the hole of male plug 1, and inserts an O-ring into the other end of the hole of male plug 1. This completes the assembly of male plug 1 assembly.
[0023] Female plug 2 assembly: It is assembled and pressed together by two plastic terminals and five copper pin females 21, and two other copper pin females 21. It is then inserted into the hole of female plug 2. A retaining ring is installed at one end of the hole of female plug 2, and an O-ring is installed in the groove on the outer diameter of female plug 2. This completes the assembly of female plug 2 assembly.
[0024] The conduit locking sleeve 41 is fitted onto the cable 4. The cable 4 end is welded to the five copper pin nuts 21 and two copper pin nuts 21 on the female plug 2 assembly. The conduit locking sleeve 41 is then tightened onto the female plug 2.
[0025] The pressure shrinking molding of the conduit locking sleeve 41 and the encapsulation molding of the injection molded sleeve 42 on the female plug 2 assembly are completed on a special equipment.
[0026] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
