Problems solved by technology
[0004] Although the electromagnetic switch with this type of wiring structure has both the metal insert type wiring structure and the bolt terminal type wiring structure, it is necessary to scrape off the insulating layer of the outer layer of the enameled wire before wiring, and connect it with the wire by winding or soldering. Only when the wiring bolts are firmly connected can the enameled wire, the wiring bolts and the metal inserts conduct electricity, and the connection and installation are troublesome; and this kind of inserts are fixed on the wiring bolts by nuts, and the stability of the inserts is poor. low firmness

Embodiment Construction
[0026] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0027] The coil seat of the electromagnetic switch is installed in the electromagnetic switch and is an important part of the electromagnetic switch, such as figure 1 , figure 2 As shown, it includes a coil, a coil support 1 , a contact 2 , a contact seat 3 and a copper sleeve 5 .
[0028] The coil support 1 is cylindrical, and the cross-section along its axial direction is "I"-shaped. The two sides of the concave are the winding part 1a for coil winding. The winding part 1a is wound with two kinds of coils: the thicker suction coil and thinner holding coils, both of which are enameled wires. A cylindrical copper sleeve 5 is fixedly connected to the inner side of the coil support 1 .
[0029] The end of one side of the...

The invention provides a coil holder for an electromagnetic switch, which belongs to the technical field of a switch and solves the problem of complicated installation, low firmness and the like in the existing wiring structure of the electromagnetic switch. The coil holder for the electromagnetic switch comprises a tubular coil support and a plurality of contact terminals; a twining part for allowing a coil to twine is arranged at the side of the coil support; contact terminal seats used for connecting the contact terminals are arranged at the end parts of the coil support near the edge; the contact terminal seats are protruded from the end parts of the coil support; line grooves I passing from top to bottom are arranged at the two sides of the contact terminal seat; line passing slots communicating the twining part with the contact terminal seats are arranged at the end parts of the coil support; line grooves II passing the two sides of the contact terminals from top to bottom and matched with the diameter of a coil plain conductor are arranged on the contact terminals; and the two sides of the line grooves II are respectively over against the two line grooves I when the contact terminals are connected to the contact terminal seats. The coil holder for the electromagnetic switch has the advantages that the coil holder for the electromagnetic switch is convenient to connect and firm to install, etc.
Description
technical field [0001] The invention belongs to the technical field of switches, and relates to an electromagnetic switch, in particular to a coil seat of an electromagnetic switch. Background technique [0002] An electromagnetic switch is a switch controlled by an electromagnet, that is, a combination of an electromagnet and a switch. Electromagnetic switches are divided into two types: AC and DC. They are used to control the on and off of long-distance and frequently-started electrical equipment. The electromagnet coil is energized by a button switch to generate electromagnetic attraction, and the movable iron core pushes or pulls the switch contacts. Closed, so as to connect the controlled circuit, otherwise, it will disconnect the controlled circuit, and control the work of high-voltage and high-current equipment with a small voltage and current, which has the advantages of safety and reliability. [0003] The wiring structure of the existing electromagnetic switch, fo...
