ターのカバーに関するものである。[Detailed Description of the Invention] [Technical Field] The cover of the round connector of the present invention is a connector used for connection to various devices such as low-power audio equipment, and for connection to various devices such as VTR and VTR television. The present invention relates to a cover for a polar or multi-pole circular connector.

部５を形成し。Conventionally, this type of circular connector is as shown in Figure 1.
A pin 3 fixed through the base 2 installed inside the earthing metal tube 1, and a surrounding area near the connecting part 4 connecting the base end of the pin 3 to the conductor A'' in the external wiring cord A. The base end side of the metal tube 1 is molded with an insulating thermoplastic resin to form the body portion 5.

いた。Furthermore, although the outer peripheral part 6 was integrally molded onto the outer periphery of the body part 5, the body part 5 was formed with heated resin, and the outer peripheral part 6 was integrally molded on top of the body part 5. Since it is molded, heat and pressure are applied each time to the connection part 6 between the pin 3 and the conductor A', which causes insulation failure.

の内径は全長に亘って同径に形成していた。For this reason, in recent years, a connector cover similar to the connector cover of the present invention has been developed, as shown in FIG. It consists of a body part A, a stepped part, and a cord protection part C. The inner circumference of the cover is approximately the same shape as the outer circumference of the large connector intended for use, and the external wiring cord is inserted from the opening side of the body. The large connector was connected to one end, the cord was inserted from the other end, the cover was slid, and the connector was inserted into the cover so that they were in close contact with each other, but the connector The structure is such that the cover is prevented from falling off by utilizing the contact resistance between the outer peripheral wall of the main body and the inner peripheral wall of the body of the cover, and between the outer peripheral wall of the cord and the inner peripheral wall of the cord protection part. The inner diameter of the cord protection part was formed to be the same diameter over the entire length.

いた。However, for large connectors, the size of the ground side metal tube is the same regardless of the number of pins, but the external wiring cord has a slightly different size depending on the number of pins of the large connector for which it is used. If we do not prepare a cord protection part with a cover that matches the size of the cord each time, there are frequent accidents where the cord falls off.
Covers of many different sizes had to be prepared, which required a large number of manufacturing molds and a huge amount of inventory.
本発明は前記問題点に鑑みて、永年の研訊の結果、前記
問題点を解消し、コードのサイズが多少相違しても使用
できる大型コネクターのカバーをを供するものである。In view of the above-mentioned problems, and as a result of years of research, the present invention solves the above-mentioned problems and provides a cover for a large connector that can be used even if the cord sizes are slightly different.
本発明の構成は大型コネクターのボディ外周へ係合溝を

条を周設し、コード保護部はテーパー状に形成し本質的
な肉厚を同厚と成した構造であり、材質は軟質熱可塑性
樹脂の塩化ビニルで成形した構成である。The structure of the present invention is that an engaging groove is provided around the outer periphery of the body of a large connector, and an engaging protrusion is provided around the inner periphery of the body of the connector cover, and the cord protection part is formed in a tapered shape to reduce the essential wall thickness. The structure has the same thickness, and the material is molded from vinyl chloride, a soft thermoplastic resin.

Engagement grooves 16 are provided around the outer periphery of the body 15 at two locations in the embodiment, and the connector cover 17 A body part 18 that covers the base end of the metal cylinder 11, a small part of the base end side, and the bodyier 5, and a cord retainer 5 part 20 that covers a small part of the cord A is extended to the body part 18 via a stepped part 19. The inner periphery of the connector cover 17 is shaped to closely embrace each covered portion of the large connector, and the inner periphery of the body 18 at a position that matches each of the engagement grooves 16. The cord protection portion 20 is formed into a tapered shape with a large diameter on the stepped portion 19 side and a small diameter on the opening side, and has an engaging protrusion 21 that can be fitted into the groove 16. The cover 17 is made of vinyl chloride, a soft thermoplastic resin.

着させると引き離すことは困難であった。In other words, the inner diameter of the cord protection part 20 is larger on the stepped part 19 side, and the other end of the external wiring cord A, which is inserted and connected to the connector main body, is inserted through the opening of the cover 17. It is inserted from the large diameter side of the cord protection part 20 which is inserted from the opening end of the cord protection part 18 and extended to the center of the stepped part 19, and is easy to insert, and is made of soft thermoplastic resin. Even if the inner diameter of the opening on the side is slightly smaller than the outer diameter of the external wiring cord A, the diameter can be expanded by the pressure for insertion, and the cover 17 can be slid to a part of the connector, and the connector provided on the outer periphery of the body 15 of the connector can be inserted. Engagement groove 16 and engagement protrusion 21 provided on inner circumference of cover 17 body 18
It can be fitted and firmly fixed, and in the prototype, once it was fixed, it was difficult to pull it apart.
