Conductive contact finger, and wiring board using the conductive contact finger

Abstract

The invention relates to a conductive contact finger, and a wiring board using the conductive contact finger. The conductive contact finger comprises a contact surface and side surfaces which are arranged to be opposite to adjacent conductive contact fingers in a circumferential direction. At least one of the side surfaces which are oppositely arranged is provided with support projections for supporting cooperation with the side surfaces of the adjacent conductive contact fingers so as to maintain rotation gaps among the conductive contact fingers in a protruding manner. According to the invention, the support projections are arranged on the side surfaces of the conductive contact fingers, such that the rotation gaps between the adjacent conductive contact fingers in the circumferential direction can be ensured, the conductive contact fingers can be provided with sufficient rotation gaps for rotation so as to be in good and uniform contact with a conductive rod and the wiring board, the resistance value is accurate, and corresponding contact parts are prevented from being damaged due to too heavy local currents.

[0002] The wiring board used for conductive connection with the conductive rod in high-voltage circuit products includes the wiring board body. There are mounting holes for assembling the contact fingers on the wiring board body. There are multiple conductive wires in the mounting hole along the circumferential direction of the hole wall. Contact fingers, each conductive contact finger is surrounded by a ring structure with a conductive perforation for the conductive rod to penetrate, and each conductive contact finger has an inner wall surface for contacting the conductive rod and for contacting the wiring board. The outer wall surface of the outer wall and the sides opposite to the adjacent conductive contact fingers on the same circumferential surface, in order to make the conductive contact fingers easier to rotate during use, they are closely connected to the conductive rods in the conductive through holes. There is enough rotation gap between adjacent conductive contact fingers to rotate each conductive contact finger, and since the side surface of each conductive contact finger in the prior art is a plane, there is no space between adjacent conductive contact fingers for holding the two sides. The support structure for the rotation gap between the two. During use, the rotation of each conductive contact finger along the circumferential direction changes the gap between adjacent conductive contacts in the circumferential direction, and even partially causes the gap between adjacent conductive fingers to disappear. But close together, cause the conductive rod to rotate during the wearing process, and the contact between the conductive contact finger and the conductive rod and the wiring board is not tight, which eventually makes the resistance value inaccurate. In severe cases, it may cause excessive local current and cause Damage to the corresponding contact parts, causing safety hazards
