Embodiment 1

[0030] refer to Figure 1-7 , this embodiment provides an easy-to-plug thermochromic secondary terminal, including a terminal 100, a housing 101, a plug 102 plugged into the housing 101, a cable 103 inside the plug 102, and a The connector 104 connected by the cable 103; wherein the housing 101 and the plug 102 are insulators, the cable 103 is embedded in the plug 102, when the plug 102 is inserted into the housing 101, the wire of the cable 103 and the connector located in the housing 101 104 contacts for current transmission; the plug-in unit 200 includes a clamping seat 201 located in the housing 101, a slider 202 located in the clamping seat 201, and a buckle 203 that conflicts with the slider 202, and the buckle 203 is connected to the plug 102 , when the plug 102 is inserted into the housing 101 , the buckle 203 is in contact with the slider 202 and will not slide out.

[0031] Specifically, in order to facilitate disassembly or installation, the housing 101 includes an...

Embodiment 2

[0039] refer to Figure 1-7 , is the second embodiment of the present invention, this embodiment is based on the previous embodiment, and the difference from the previous embodiment is: the surface of the housing 101 is wrapped with a thermochromic powder 106 (not shown in the figure), preferably, The temperature-sensitive color-changing powder 106 adopts the microencapsulated reversible temperature-sensitive color-changing substance in the prior art. The particles of this pigment are spherical, with an average diameter of 2-7 microns (one micron equals one thousandth of a millimeter). Its inside is a color-changing substance, and the outside is a transparent shell with a thickness of about 0.2-0.5 microns that neither dissolves nor melts. The basic temperature of its temperature-sensitive discoloration is: -5°C, 0°C, 5°C, 10°C, 16°C , 21°C, 31°C, 33°C, 38°C, 43°C, 45°C, 50°C, 65°C, 70°C, 78°C, thermochromic powder 106 is prepared from electron transfer organic compound system...

Abstract

The invention discloses an easy-to-plug thermochromic secondary wiring terminal, which comprises a wiring terminal, a shell, a plug plugged with the shell, a cable positioned in the plug, and a connecting piece connected with the cable. A plugging unit comprises a clamping seat located in the shell, a sliding block located in the clamping seat and a buckle abutting against the sliding block, and the buckle is connected to the outer side of the plug. Connection or disconnection of the secondary wiring terminal of the device only needs simple pressing. Pressing entry during connection is realized, popping out by slightly pressing in the case of disconnection is realized, wiring of the secondary wiring terminal is more reliable and safer; during connection, the plug is pressed into the shell;during disconnection, the plug can be pulled out by pressing the plug slightly, convenience and quickness are achieved, discoloration can be quickly perceived and connection of the terminal is disconnected when the temperature of the terminal is too high and dangerous, potential current open circuit and other hidden dangers can be found in time, a current transformer and other devices are prevented from being damaged due to open circuit, and then reliable operation of secondary devices is ensured.

Description

technical field [0001] The invention relates to the field of electric power safety, in particular to an easy-to-plug temperature-sensitive and color-changing secondary terminal. Background technique [0002] Secondary terminals are widely used in substations. The operating condition of the terminal is generally relatively healthy, and it is only necessary to perform periodic visual inspection, dust removal, and temperature detection on the daily basis. As a kind of connector, the terminal block is an important component in the electrical industry. It plays an irreplaceable and non-negligible role. Because engineers and technicians first check the interface, that is, the terminal, when overhauling, the terminal block design is particularly important. The terminal block is used to facilitate the connection of wires. It is actually a piece of metal sealed in insulating plastic. There are holes at both ends for inserting wires, and there are screws for fastening or loosening. ...
