Quickly-connected inserting sheet, contactor with quickly-connected inserting sheet and assembly method thereof

Abstract

The invention discloses a quickly-connected inserting sheet, a contactor with the quickly-connected inserting sheet and an assembly method thereof. The contactor comprises a connection screw, the quickly-connected inserting sheet, a connection terminal and a body. A screw abdication hole is arranged in the body under the connection terminal. The quickly-connected inserting sheet comprises a head, a middle part and a tail. The quickly-connected inserting sheet is installed in the body and cooperates with the connection terminal. The bending direction of the tail of the quickly-connected inserting sheet is largely parallel to the head. A clamp head is arranged on the tail end of the tail. A clamp groove is arranged in the outer side of the screw abdication hole of the body. The tail of the quickly-connected inserting sheet is arranged in the clamp groove of the body in a cooperative manner and clamped in the joint of the screw abdication hole and the clamp groove via the clamp head so as to stop the quickly-connected inserting sheet from being pulled out towards the outer side direction of the quickly-connected inserting sheet. According to the invention, by improving the structure of the quickly-connected inserting sheet, parts are simple to process, operability of assembly is high, cost is low and the undesirable phenomena such as deformation or pulling out which will affect use of clients will not occur.

Description

technical field [0001] The invention relates to a contactor, in particular to a quick-connect insert, a contactor with a quick-connect insert and an assembly method thereof. Background technique [0002] A contactor refers to an electrical appliance that uses a coil to flow through a current to generate a magnetic field to close the contacts in industrial electricity to control the load. When the contactor coil is energized, the coil current will generate a magnetic field, and the generated magnetic field will cause the static iron core to generate electromagnetic attraction to attract the moving iron core, and drive the contactor contact to move, the normally closed contact is disconnected, and the normally open contact is closed. linked. When the coil is powered off, the electromagnetic attraction disappears, and the armature is released under the action of the release spring to restore the contacts, the normally open contacts are disconnected, and the normally closed con...

AI Technical Summary

Problems solved by technology

[0004] 1. The interference between the tail of the quick-connect insert and the body is too large, which makes assembly difficult and even fails to fit

[0005] 2. When the interference between the tail of the quick-connect insert and the body is too small, when the customer pulls out the socket, the direction A of the pull-out force is perpendicular to the forming direction B of the structural material at the end of the insert, about 90° (see figure 1 ), it is easy to pull out or deform the tail of the insert; on the other hand, in order to solve the problem of being affected by the vibration during transportation when the screw reserves the wiring gap, the insert must move upwards, resulting in a smaller reserved gap. It is difficult for customers to connect wires, and the tails of the inserts in the existing technical solutions must be very long; but this structure not only leads to increased costs, but also is easy to deform during the production process, which in turn affects the interference fit
