Background
When motor multistage stator is connected, the motor stator lead wire all adopts the lead wire direct welding mode at present, and this kind of lead wire mode has following problem: the leading-out wire end is not fixed, soldering tin is easily influenced by thermal stress, mechanical stress, welding wire space and the like, the soldering tin is easily cracked, insulation cannot be guaranteed, welding is difficult, the service life of a motor is low, and the like.
Disclosure of Invention
In order to solve the problem provided in the background art, the utility model aims to provide a contact pin structure for connecting motor stator.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a contact pin structure of usefulness is connected to motor stator, is including setting up the lead wire on the motor stator who winds the good coil, its characterized in that: the contact pin structure include the insulating disc and inlay in a plurality of contact pins on the terminal surface of insulating disc, the insulating disc set up in the connecting end between the motor stator, including the coil parcel in the stator of insulating disc, the lead wire of coil is drawn forth by the slotted hole of seting up on the terminal surface of insulating disc, the contact pin be L shape, the vertical section of contact pin be cylindricly and by the insulating disc terminal surface wear out, the horizontal section of contact pin be the platykurtic and paste lean on install in the rear side of insulating disc, be provided with on the horizontal section of contact pin with the slotted hole cooperation lead wire hole that corresponds, the lead wire draw forth from the slotted hole after wearing out by the lead wire hole.
As the utility model discloses preferred, insulating disc injection moulding.
As the utility model discloses preferred, contact pin integrated into one piece.
As the utility model discloses preferred, contact pin quantity be 3.
As the utility model discloses it is preferred, motor stator's both ends all are provided with the contact pin structure.
Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model discloses a to inlay the insulating disc that moulds plastics that has the contact pin and set up the link between motor stator, not only contain the coil wire winding and play the insulating effect, simultaneously through the slotted hole of seting up on the insulating disc of moulding plastics, the slotted hole is worn the hole with the lead wire on the contact pin and is concentric, has increaseed the bonding wire space. The utility model discloses a contact pin that will connect the multistage stator sets up to L type structure, and the horizontal section of L type structure is embedded in the insulating disc of moulding plastics, can not only effectively reduce the contact pin space, and bonding wire simple process has saved the insulating link of package moreover, and welding quality is reliable. Meanwhile, the contact pins are adopted for connection, so that welding in a limited space is not needed, and the production efficiency is greatly improved. 2. The vertical section of the contact pin is set to be cylindrical and is connected with the lower section stator structure in a plugging way; the transverse section of the contact pin is flat, so that the contact pin can be abutted against the inside of the insulating disc, and the mounting and positioning space of the contact pin is greatly reduced.
