Problems solved by technology
Therefore, when assembling the coil terminal accommodating cavity structure in the prior art, it is necessary to repeatedly screw the first screw and the second screw, the assembly process is relatively complicated, and automatic assembly cannot be realized
[0004] In order to prevent dust from entering the cavity structure of the coil terminal and at the same time improve the protection level, usually after the coil skeleton is installed in the body, a protective cover for the coil terminal is specially set on the body, which makes the overall plastic parts too much, the structure is more complicated, and increases cost

Embodiment Construction
[0042] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0043] refer to Figure 1a to Figure 5 As shown, the present invention takes a contactor as an example to disclose a coil terminal accommodating cavity structure in detail, and a first accommodating cavity 1 and a second accommodating cavity 2 are formed on the coil bobbin 10 .
[0044] The first conductive metal plate 3 is installed in the first accommodating cavity 1 and is electrically connected with one end of the coil. An opening 11 is provided on one side of the first accommodating cavity 1, and the first screw 5 is placed in the first through the opening 11. In the accommodating cavity 1, a position-limiting structure 12 is formed on the side wall of the first accommodating cavity 1 to limit the falling of the first screw 5, such as Figure 3b As shown, the top of the first accommodating chamber 1 forms a through hole 13 opposite to t...

The invention discloses a coil wiring terminal accommodation chamber structure. Accommodation chambers, the side portions of which are respectively provided with an opening, are formed on a coil framework; conductive metal plates are arranged in the accommodation chambers respectively and are in electrical connection with coils respectively; a limitation structure is formed in each accommodation chamber, so that a screw can be installed from the opening at the side portion of each accommodation chamber without falling off; the top portion of each accommodation chamber is provided with a through hole with the IP2X protection level, the hole diameter of the through hole being slightly larger than the outer diameter of the head portion of the screw; and the front side wall of each accommodation chamber is provided with an open slot so as to enable the conductive metal plate to be exposed. The chamber structure is concise and reliable in structure; a special coil wiring terminal protective cover is not needed; the screws can be replaceable; the chamber structure is suitable for automatic assembly; and the production cost is reduced.
Description
technical field [0001] The invention relates to a structure for accommodating a coil terminal. Background technique [0002] In the prior art, for some electrical appliances such as contactors and circuit breakers, the coil is usually wound on the bobbin, and one end of the coil is electrically connected to the first conductive metal plate, and the first screw is locked on the first conductive metal plate to form a second A connection terminal, and the other end of the coil is electrically connected to the second conductive metal plate, and the second screw is locked on the second conductive metal plate to form a second connection terminal. [0003] When assembling the coil terminal accommodating cavity structure, first screw the first screw into the first conductive metal plate, screw the second screw into the second metal plate; then screw the first screw into the first conductive metal plate, And the second screw and the second metal plate are inserted into the coil fram...
