Embodiment 1

[0017] Embodiment 1 (single head crown spring type contact ring formal installation) as figure 2 As shown, the crown spring socket contact includes a pressure ring 4 with a central hole, a crown spring contact ring 2 and a tubular socket 1, and the crown spring contact ring 2 is installed in the inner hole of the tubular socket 1, The front end of the inner hole of the tubular jack 1 is provided with a flaring section, and its aperture is larger than the straight hole section at the rear end. There is a tapered hole transition section between the flaring section and the adjacent straight hole section. A pressure ring 4 is installed in the hole section, and the pressure ring 4 has a central hole for the insertion pin to pass through. The tail end of the pressure ring 4 cooperates with the inner hole expansion section of the tubular jack 1. One end of the spring type contact ring 2 is provided with U-shaped grooves and contact strips evenly distributed on the circumference. Be...

Embodiment 2

[0018] Embodiment 2 (single head crown spring type contact ring reverse installation) such as Figure 4 As shown, the contact piece includes a tubular socket 1, a crown spring contact ring 2 and a pin 3, the crown spring contact ring 2 is placed in the inner hole of the tubular socket 1, and one end of the crown spring contact ring 2 is provided with U-shaped grooves and contact strips evenly distributed on the circumference, the arc transition at the root of the U-shaped grooves can avoid stress concentration. Between the straight hole section of the inner hole of the hole 1 and the mating surface of the front end of the pin 3, the other end gap is assembled in the straight hole of the tubular jack 1. In this contact piece, one end of the crown spring contact ring is crimped between the tail end of the tubular jack and the front end of the pin, and the interference fit between the tubular jack and the pin ensures that the contact strip of the crown spring contact ring is pres...

Embodiment 3

[0019] Embodiment 3 (double-ended crown spring type contact ring) such as Figure 5 As shown, the crown spring socket contact includes a pressure ring 4 with a central hole, a crown spring contact ring 2 and a tubular socket 1, and the crown spring contact ring 2 is installed in the inner hole of the tubular socket 1, Slots and contact strips are evenly arranged around the two ends of the crown spring contact ring 2, and the inner hole of the tubular jack 2 is provided with a mating surface with the pressure ring 4 and the pin 3, and the contact between the two ends of the crown spring contact ring 2 The strips are placed between the corresponding mating surfaces, and the two ends of the crown spring type contact ring are fixed through the matching connection of the tubular jack, the pressure ring and the pin.

[0020] In this contact piece, one end of the crown spring type contact ring is crimped on the tail end of the pressure ring and the front end of the tubular socket, th...

Abstract

The invention discloses a crown spring jack contacting piece which comprises a tubular jack, a crown spring type contact ring and pins, wherein the crown type contact ring is installed inside the tubular jack; the pins are connected with the rear end of the tubular jack; and one or two ends of the crown spring contact ring inside the tubular jack is fixed. The crown spring jack contacting piece with the adoption of the structure has the advantages of being simple in structure, small in plugging force and reliable in contact.

Description

technical field [0001] The invention belongs to the technical field of connectors, in particular to a high-reliability crown spring receptacle contact piece. Background technique [0002] An existing crown spring socket contact such as figure 1 As shown, it includes a sheath 1, a crown spring contact ring 2 and a pin 3. The crown spring contact ring 2 is placed in the sheath 1, and the sheath 1 and the pin 3 are fixed by riveting three points or a pressure ring. The disadvantage of this kind of contact is that the crown spring contact ring 2 can move axially and radially in the sheath 1, and it is easy to come out from the orifice of the sheath 1, which leads to the failure of the contact and cannot meet the high reliability requirements. Contents of the invention [0003] The purpose of the present invention is to provide a highly reliable crown spring socket contact to solve the problem of axial and radial serial movement and easy detachment of the crown spring contact ...
