Embodiment Construction

[0060] Embodiments of the electromagnetic coil of the present invention will be described in detail below with reference to the drawings.

[0061] figure 1 It is a schematic perspective view of the overall structure of the skeleton of the electromagnetic coil with pins according to the first embodiment of the present invention. figure 2 for figure 1 A perspective view of an electromagnetic coil with winding wire wound in it. The structure of the electromagnetic coil indicated by reference numeral 1 as a whole is the same as that of the prior art, that is, it is composed of a skeleton 2 formed of resin, a winding wire 3 and a pin 4 . The frame 2 is composed of a pair of parallel hollow disc-shaped flange parts 2a and 2b, and a winding part 5 for winding the winding wire 3 is arranged between the flange parts 2a and 2b. The collar portion 2b is integrally formed with the retaining portion 6 for mounting the pin 4 on the side surface 2b1 thereof. However, the pins 4 are not ...

Abstract

The invention discloses an electromagnetic coil comprising a framework, a wound coil and inserted pins. The framework is provided with a pair of blade-shaped parts arranged in parallel and is also provided with a coil winding part arranged between the blade-shaped parts and used for winding the coil winding part; the side surface of one end of the blade-shaped parts is provided with an inserted pin retaining part; and the wound coil is connected to the inserted pin. The electromagnetic coil is characterized in that the inserted pin retaining part consists of a plurality of convex parts and a plurality of concave parts which are arranged between two adjacent convex parts; the inserted pins are inserted in the convex parts, and the end surfaces of the inserted pins are protruded from the convex parts; the wound coil passes by the concave parts, and the head of the wound coil is wound and welded on one end of each inserted pin. Due to the inserted pin and the fixed inserted pin retaining part, the inserted pins can be reliably inserted in the framework, keeping a certain insulating space with each other, and the wound coil can be reliably connected with the inserted pins. The invention also discloses the framework of the electromagnetic coil, and a retaining part of the framework consists of convex parts and concave parts, which are arranged successively.

Description

technical field [0001] The present invention relates to an electromagnetic coil and its skeleton, in particular to a structure for maintaining the connection between the contact pin and the winding wire for energization. Background technique [0002] Conventional electromagnetic coils for control, for example, Japanese Patent Application Laid-Open No. 8-65994 and Patent Publication No. 3-34671 disclose the connection structure between coil winding wires and coil lead-out wires. However, in the above-mentioned existing electromagnetic coils, the problem of setting the holding part of the pin and the configuration of the connecting winding on the pin is not taken into account. The connection structure is more complicated, the process operation is more cumbersome, and the connection between the winding and the lead wire is not enough. reliable. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electromagnetic coil...
