Quick-connect insert, contactor with quick-connect insert and assembly method thereof

Abstract

The invention discloses a quick-connection insert, a contactor with a quick-connection insert and an assembly method thereof. The contactor includes a connecting screw, a quick-connection insert, a connection terminal and a body; a screw is provided at the position of the body below the connection terminal Make way holes; the quick-connect insert includes a head, a middle part and a tail; the quick-connect insert is loaded into the body and matched with the connecting terminal; the tail of the quick-connect insert is bent to a position roughly parallel to the head, and The end of the tail is provided with a clip head; the outer side of the screw relief hole of the body is provided with a card slot; the tail of the quick-connect insert fits in the card slot of the body, and is stuck in the screw relief hole and the card slot through the clip head The junction of the quick connectors is used to limit the pulling out of the quick connectors to the outside of the connectors. The invention has the advantages of simple parts processing, strong assembly operability and low cost by improving the structure of the quick-connecting insert, and will not cause deformation, pull-out and other adverse phenomena that affect the use of customers.

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
