- the utility model comprises an upper part and a lower part which are connected to each other; the lower part of the lead-out positioning sleeve is sleeved with the lead-out end cover (for example, the lower part of the lead-out positioning sleeve is sleeved in
- the lead-out cable 4 needs to be positioned in the card-line structure; in addition, when the cable lead-out positioning is completed, an additional lead-out is required.
- the positioning sleeve 3 is fixed on the outlet end cover 2; The products are complicated in the assembly operation and relatively high in the operation requirements of the workers.
- the existing product also needs to be led out of the positioning sleeve 3, and the epoxy resin 7 is potted, and the structure is used to realize the insulation and positioning.
- This structure not only increases the material cost of the product, but also further assembles the product. The operating process is complicated.
- the object of the present invention is to provide a sealed cable lead-out capacitor formed by injection molding and an injection molding forming method, which mainly solves the complicated structure of the existing cable lead-out capacitor (especially, has a lead-out positioning sleeve), resulting in high product cost and assembly operation.
- the complicated technical problem not only simplifies the product structure, reduces the cost, but also further simplifies the production process of the product, and also makes the capacitor have a good sealing property.
- the present invention is achieved as follows:
- a sealed cable lead-out capacitor formed by injection molding comprising a capacitor body having a capacitor core inside, the upper end surface of the capacitor body having a solder bump connected to a lower end of the lead cable; the upper end surface of the capacitor body The solder joint is on the take-up end cap; the injection molding plastic covers the upper end of the capacitor body and extends to the upper portion and the upper portion of the metal shell, and the injection molding plastic wraps the end cap and the lead cable is also positioned In injection molding plastics.
- the sealed cable-carrying capacitor formed by the injection molding is characterized in that: the upper end of the injection molding plastic is injection-molded to form a lead-out tube, and the lead cable is passed through the lead-out tube.
- the sealed cable lead-out capacitor formed by the injection molding is characterized in that: the lead end cover has a peripheral ring, and the peripheral ring surrounds the solder joint.
- the capacitor body is placed in the capacitor body slot of the injection mold, and the lead cable is placed in the cable positioning groove, and the outer ring on the end cover is placed in the outer ring groove;
- the top block on the injection mold is placed against the bottom of the capacitor body to fix the capacitor body to prevent displacement of the capacitor body during the injection molding process. At the same time, the top block is placed against the bottom of the capacitor body, and the capacitor body encloses the injection tank and the upper space thereof. Injection cavity;
- the special injection mold further comprises an extraction tube injection groove, which is disposed between the peripheral ring positioning groove and the cable line positioning groove, and is used for injection molding of an injection molding structure in which an extraction pipe is required.
- the present invention does not need to process and take out the positioning sleeve, and therefore, it is not necessary to add a cable to pass through and position the process step of pulling out the positioning sleeve in the assembly process.
- the injection molding plastic of the capacitor of the present invention covers the upper end of the capacitor body and extends to the upper portion and the upper portion of the metal casing (that is, the structure for wrapping the upper portion of the metal casing), and the injection molding plastic is integrally formed with the metal casing of the capacitor body, so that the capacitor has More good sealing.

- the injection molded plastic 8 encloses the lead end cover 2 therein, and the lead cable 4 is also positioned in the injection molded plastic 8.
- the upper end of the injection molded plastic 8 is injection molded to form a lead-out tube 81 through which the lead cable 4 is passed.
- the present invention also includes a structure in which the extraction tube 81 is not injection molded.
- the special injection mold 10 is composed of upper and lower molds, and a capacitor body groove 104, a peripheral ring positioning groove 103 and a cable positioning groove 101 are sequentially arranged from bottom to top in the cavity.
- a top block 105 is disposed under the capacitor body slot 104;
- the periphery of the upper end of the container body groove 104 is further provided with a capacitor body that is in communication with the injection molding groove 106; the specific steps are as follows:
- the capacitor body is placed in the capacitor body slot 104 of the injection mold 10, and the lead cable 4 is placed in the cable positioning slot 101, and the peripheral ring on the outlet cover is placed in the peripheral ring groove 103;
