Fast plug-unplug wiring terminal block

Abstract

The invention discloses a fast plug-unplug wiring terminal block, which comprises a pedestal and a metal piece, wherein the metal piece is arranged in the pedestal, the pedestal comprises a plug connecting cavity, a lead wire fixing cavity and an accommodating cavity, accordingly, one end of the metal piece is a plug connecting end and the other end is a lead wire connecting end, and the front endof the plug connecting end is provided with a protrusion matching a plug; the lead wire fixing cavity is further internally provided with a back connecting type spring, one end of the back connectingtype spring is connected with the lead wire connecting end, a through hole is formed in the other end of the back connecting type spring, the lead wire connecting end is arranged in the through hole,the pedestal is further provided with a wiring port, the position of the wiring port corresponds to the position of the through hole, and one side of the wiring port is provided with a screwdriver inlet. According to the fast plug-unplug wiring terminal block, and the plug connecting end is provided with the protrusion capable of cooperating with the matched plug, such that the terminal block ismore tightly connected and the connection is firm; and the terminal blocks can be connected by means of a terminal block connection device, so that the terminal block of different numbers can be connected according to the needs without the need for a customized mold, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a quick plug-in terminal block. Background technique [0002] Terminal block, also known as electrical connection terminal, terminal block, refers to a seat with one or more circuit connections that can be inserted, through which various connections can be inserted to facilitate connection with other circuits. It is mainly used to transmit signals and conduct electricity. It plays the role of connection and conduction. Different electrical equipment has different terminal blocks, and the corresponding standards of terminal blocks applied to different devices are also different; [0003] The existing terminal base has the following deficiencies: 1: the plug connection end of the existing terminal base is a straight pin, and the plug terminal base is connected by a straight pin, and the straight pin does not have a locking function, so that the existing plug will be i...

Problems solved by technology

[0003] The existing terminal base has the following deficiencies: 1: the plug connection end of the existing terminal base is a straight pin, and the plug terminal base is connected by a straight pin, and the straight pin does not have a locking function, so that the existing plug will be inserted into the terminal base It is not firmly inserted when plugged in, and it is easy to fall off, and there are many wires in large-scale equipment, so the number of terminal blocks required is also large, and vibration will occur when the equipment is running. If multiple plugs are not inserted firmly, the vibration may make the plug terminal block loose If it falls off, it will cause many failure points of the equipment, and due to the large number of wires, it is also very difficult to overhaul, and there is no way to use it normally, causing serious safety hazards;

[0004] Two: The number of wires in existing large-scale equipment is very large, and the number of wires in each group is not necessarily the same. For example, some groups have 3 wires, some groups have 5 wires, and some groups have 10 wires, etc. , and there are many groups with the same number of wires, such as a group of 3, etc.; since each wire must be connected to the circuit, when all the wires in a group are fixed together and each wire is respectively connected to the circuit, This group of special molds needs to be customized, but the number of wires in each group may be different, so the molds that need to be customized for each group may also be different; due to many groups, these groups may have the same number of wires or different numbers of wires, but one The group needs a mold, so there are many types of molds, and the quantity of each mold is also very large. The number of molds is time-consuming and labor-intensive, and it is easy to make mistakes during assembly. Mixing them will cause the end product to burn out and cause great economic losses.
