Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The utility model discloses a choke convenient to installation, as shown in fig. 1 and 2, including choke main part 1, as shown in fig. 3, choke main part 1 is equipped with coil 11 and iron core ring 12, and the material of coil 11 is the enameled copper wire, and coil 11 twines on iron core ring 12, and coil 11 is formed with lead-out wire 13, and lead-out wire 13 is used for connecting circuit.

As shown in fig. 1 and 2, including the coil base 2, as shown in fig. 4 and 5, the coil base 2 is formed with a bottom gasket 21, and an enclosing wall portion 22 is formed on an upper side surface of the bottom gasket 21, as shown in fig. 1 and 2, the coil 11 and the core ring 12 are disposed in a cavity defined by the enclosing wall portion 22 and the bottom gasket 21, and the enclosing wall portion 22 may correspondingly enclose a middle lower portion of the coil 11. As shown in fig. 3, the outgoing line 13 is sleeved with an insulating tube 131 (specifically, two ends of the coil 11 are respectively sleeved with the insulating tubes 131), the insulating tube 131 may be a plastic tube, in order to connect the circuit, the end of the outgoing line 13 needs to be stripped off the insulating paint layer to form a conductive end 132, and the conductive end 132 is integrally connected with the enameled copper wire of the coil 11. As shown in fig. 4 and 5, the coil holder 2 is formed with a positioning groove 23 extending along the central axis direction of the core ring 12 (the positioning groove 23 is arranged along the up-down direction as seen from the visual direction of fig. 1), the lower end of the positioning groove 23 is connected with the bottom gasket 21 into a whole, so that the entire coil holder 2 can be manufactured by injection molding, as shown in fig. 1 and 2, the insulating tube 131 is fitted into the positioning groove 23 (i.e., the insulating tube 131 is inserted into the positioning groove 23 together with the two end terminals of the coil 11).

The assembly process of the choke body 1 and the coil holder 2 is as follows: firstly, the insulating tube 131 is sleeved on the two end terminals of the coil 11, then the coil 11 together with the core ring 12 is plugged into the cavity surrounded by the enclosure part 22 and the bottom gasket 21, and then the leading-out wire 13 with the insulating tube 131 is correspondingly plugged into the positioning groove 23, as shown in fig. 1, the choke body 1 and the coil holder 2 are assembled.
