Description

Technical Field

[0001] This utility model belongs to the field of high-frequency head technology, and specifically relates to a high-frequency head PIN pin assembly with high gripping force. Background Technology

[0002] The PIN pins of the high-frequency head consist of a pin tip section and a connecting section. The connecting section uses a spring clip for clamping connection. In the current structure, the general requirement for the spring clip's clamping force is: after inserting and pulling a 1.0 PIN pin 100 times, and then inserting a 0.8 PIN pin, it can support a weight of over 80g.

[0003] However, some customers now require higher clamping force from the spring clips, demanding several times the hanging weight. Existing spring clip clamping structures on both sides are generally "><" shaped, thus their clamping force is relatively limited. Therefore, the current spring clip structure for the PIN connector section cannot meet these requirements.

[0004] Improving the gripping force of the frequency head PIN pins is the direction of our research and development. Utility Model Content

[0005] This invention provides a high-frequency head PIN pin assembly with high gripping force, which can solve the problems pointed out in the background art.

[0006] A high-frequency head PIN needle assembly with high gripping force includes a PIN needle, the PIN needle including a needle tip section and a connecting section, the connecting section being a connecting tube body, and elastic clips symmetrically formed on the tube wall of the connecting tube body.

[0007] Preferably, the end of the elastic clip has an inwardly recessed clamping portion.

[0008] Preferably, the upper end of the elastic clip has outwardly protruding reinforcing ribs.

[0009] Preferably, the needle section and the connecting section are integrally formed by rolling a metal sheet, and the connection between the two is treated with a diameter change.

[0010] Preferably, the metal sheet is a copper sheet or a stainless steel sheet.

[0011] Preferably, it also includes a protective core housing, which includes an upper housing and a lower housing. The PIN needle is inserted into the upper housing from one end of the needle tip, and the lower housing is detachably connected to the upper housing.

[0012] Preferably, the upper housing and the lower housing are inserted into each other. The upper housing includes an insertion section and an end cap. The end cap is a conical end cap. The connecting end of the lower housing is provided with a conical hole section that mates with the conical end cap.

[0013] Preferably, the connecting tube is a circular connecting tube.

[0014] Beneficial effects: This utility model provides a high-frequency head PIN needle assembly with high gripping force. The elastic clips are symmetrically opened on the tube body, especially the round tube body. Compared with the existing structure, the tube body itself has a high radial deformation resistance, that is, it can provide a stronger radial clamping force, thereby improving the gripping force of the connecting section. In addition, the inwardly recessed clamping part and the outwardly protruding reinforcing rib can improve the gripping force, deformation resistance and strength to a certain extent.

[0015] The protective core housing has also undergone corresponding structural adjustments to adapt to the changes in the PIN pin structure. Attached Figure Description

[0021] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0022] Example 1: As Figure 1 As shown, a high-frequency head PIN needle assembly with high gripping force includes a PIN needle, which includes a needle tip section 1 and a connecting section 2. The connecting section 2 is a connecting tube body, which is a circular connecting tube body. Elastic clips 21 are symmetrically provided on the tube wall of the connecting tube body. Specifically, the end of the elastic clip 21 has an inwardly recessed clamping part 22, that is, the end of the elastic clip 21 has an inwardly recessed arc-shaped clamping end.

[0023] In some embodiments, the upper end of the elastic clip 21 has an outwardly protruding reinforcing rib 23, which can provide a certain elastic clamping force and improve strength.

[0024] Specifically, the needle section 1 and the connecting section 2 are integrally formed by rolling a metal sheet, and the connection between the two is made with a diameter change. The metal sheet is a copper sheet or a stainless steel sheet.

[0025] Example 2: Special Combination Figure 2-3 As shown, it also includes a protective core housing, which includes an upper housing 31 and a lower housing 32. The PIN needle is inserted into the upper housing 31 from one end of the needle tip 1. The lower housing 32 is detachably connected to the upper housing 31, and the upper end of the connecting section 2 is tightly fitted with the upper housing 31.

[0026] Specifically, the upper housing 31 and the lower housing 32 are inserted into each other. The upper housing 31 includes an insertion section 311 and an end cap 312. The end cap 312 is a conical end cap. The connecting end of the lower housing 32 is provided with a conical hole section that mates with the conical end cap. The conical end cap and the conical hole section are tightly fitted together.
