The utility model discloses a needle-punching binding post, when connecting cable 8 and second cable 7, the 1 st thorn of metallic connection needle inserts second cable 7, and second metallic connection needle 5 impresses cable 8 to make needle-punching binding post's most structure all hide inside the insulating skin of advancing the cable, the installation space of needs is little, has avoided electrified metallic interconnect structure to expose, has avoidd electric leakage short circuit risk.

In order to improve the connection reliability of the second metal connecting pin 5 and the th cable 8, a fixing structure is arranged on the end face of the opening position of the end cover 2, and the fixing structure is connected to the outer surface of the th cable 8, so that the connection of the second metal connecting pin 5 and the th cable 8 is ensured to be more reliable.

Specifically, fixed knot constructs for being used for embracing the sheetmetal 3 of cable tightly, as shown in fig. 1 and 3, sheetmetal 3 includes two card wings that are used for embracing the cable tightly, two the card wing sets up along the axis direction staggers, has prolonged the fixed length, effectively prevents the utility model discloses a needle-punched binding post and cable 8 throw off to guarantee that second metallic interconnect needle 5 and cable 8 are connected, the axis described here refers to the axis of end cover 2.

In other embodiments, two of the snap fins are symmetrically arranged in the axial direction, and the two snap fins are positioned around in the pair of end caps 2.

In another embodiment, as shown in fig. 4 and 5, the metal sheet 3 includes four clamping fins for holding the cables tightly, specifically, two sets of clamping fins are symmetrically arranged along the axial direction, so as to further improve the connection reliability of the pin terminals and the cable 8.

, in order to facilitate the metallic connecting needle 1 to penetrate into the insulation layer of the cable, the metallic connecting needle 1 is a conical structure, wherein the conical structure comprises a conical structure and a pyramid structure, it can be understood that the conical top of the conical structure is the needle point of the metallic connecting needle 1, and the second metallic connecting needle 5 is a cylindrical structure.

In the specific embodiment of , the metallic connecting pin 1 is in a pyramid structure, and the metallic connecting pin 1 is prevented from rotating relative to the connecting cable by arranging the metallic connecting pin 1 in a pyramid structure, so that the reliability and stability of the connecting position are ensured.
