Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, fig. 2 and fig. 3, in an embodiment of the fixing device for the line outgoing position and the mold position of the present invention, the fixing device includes a fixing plate 1, a first card 2 and a second card 3, the first card 2 and the second card 3 are vertically disposed on the fixing plate 1, the first card 2 and the second card 3 are disposed in parallel and form a PCB card position slot 8 therebetween, and the distance between the PCB card position slot 8 and the PCB thickness are adapted to each other. The fixing device can be well clamped on the PCB through the PCB clamping groove 8.

The fixing device is fixed on the PCB board, which is mainly used for facilitating the welding of the wires on the PCB board. Therefore, the fixing plate 1 of the present embodiment is provided with the wire outlet 5, and the electric wire can be led out from the wire outlet 5, thereby facilitating welding. And for the convenience of welding, be equipped with welding hole 4 on the first card 2 of this embodiment, this welding hole 4 is corresponding with the solder joint position of PCB board, and the two position corresponds promptly, and it is also corresponding with welding hole 4 position certainly to go out wire hole 5, and like this, the back is drawn forth from wire hole 5 to the electric wire, can just to the welding point on the PCB board through welding hole 4, then directly accomplish the welding operation of electric wire on welding hole 4, consequently, this fixing device can be more firm accurate with the welding of electric wire.

Certainly, in order to facilitate the fixation and the injection molding of the electric wire, the embodiment is further provided with a wire casing 7, the wire casing 7 is led out from the wire outlet 5, the electric wire can be inserted into the wire casing 7 and led out from the wire outlet 5, and the flat cable is more standard.

Simultaneously, still including U-shaped opening 6 on the first card 2 of this embodiment, this U-shaped opening 6 sets up side by side with welding hole 4, and this U-shaped opening 6's setting can effectively avoid welding or package to mould the in-process and play certain cushioning effect.

Preferably, the inner surface of the fixing plate 1 of the present embodiment is a cambered surface structure so as to be adapted to the circular edge structure of the PCB board in the product such as the motor. Of course, the inner surface of the fixing plate 1 may be of other structures adapted to the edge structure of the PCB of each product. And the fixture fixing plate 1, the first card 2 and the second card 3 of the present embodiment may be integrally formed. The fixture of this embodiment is made of PA66 material. The PA66 is a high-temperature resistant material and can effectively adapt to the high-temperature environment generated in the plastic coating process.

The fixing device is of a wire frame structure, and the absolute size of the electric wire between two fixed wires is matched with the absolute size of the outgoing wire of the die. In the specific implementation, as shown in fig. 4 and 5, the electric wire is inserted into the fixing device 10, then the fixing device 10 is inserted into two points of the PCB 20 of the motor 30 to be soldered, and then the two points are soldered, and finally the two points are placed into the mold 40 for plastic coating. The electric wire is required to be put into the mold chute during the putting into the mold 40. Through test comparison, 1) the device is not added in the plastic coating process of the existing motor, the motor is not waterproof thoroughly, and absolute waterproof can be realized after the device is added; 2) the plastic materials can be exploded out of the mould along with the electric wire in the plastic coating process of the existing motor, and the phenomenon does not occur after the motor is added into the device; 3) the phenomenon that an electric wire can be broken or broken after the existing motor is coated with plastic is completed, and after the motor is added with the motor, the phenomenon is rarely outgoing. Therefore, the device greatly improves the product yield and the cost, and the plastic coating efficiency is higher.

Based on above-mentioned device, the embodiment of the utility model provides a still provide an injection moulding product, this injection moulding product is including moulding plastics body and foretell fixing device. And the injection molded product of the present embodiment is preferably a motor.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
