Description

The multiport type socket connector

Affiliated technical field

The utility model discloses a kind of multiport type socket connector, has the multiport type socket connector of error-proof structure when especially relating to a kind of assembling operation.

Background technology

In the middle of the home theater electronic equipment, as TV, DVD, electronic installations such as sound equipment, for realizing the connection between the home theater electronic installation and realizing audio frequency, video signal transmission, must be provided with audio-visual jack interface between its electronic installation, as single audio-visual socket being located among the electronic installation, must be provided with and a plurality ofly just can meet the demands, certainly will strengthen electronics appearance structure is set, therefore a plurality of single audio-visual sockets are made into integrally formed multiport type socket, described multiport type socket connector comprises the insulating body that is provided with identical a plurality of tubular protuberances, earthing member, conducting terminal, the upper shield and a plurality of tubular shell that are placed on the tubular protuberance of insulating body are formed, because the tubular protuberance shape of several insulating bodies is identical, and connector is realized video, audio signal transmission connects, must its color be distinguished when connecting for extraneous the plant, to prevent the mistake of pegging graft, therefore, the branch that the described upper shield that is placed in the tubular protuberance of insulating body has color, as red, in vain, the color that Huang etc. are different, and the different colours upper shield is linked in and needs on the tubular protuberance to be inserted in certain sequence, and when pipelining at present, the color upper shield often adds mistake, whether adorn mistake by rear end processing procedure inspection upper shield again, must re-assembly again, production efficiency is on the low side.If provide use with the multiport type socket connector of matching error, often produce phenomenons such as signal interruption.

Therefore, at the above-mentioned existing defective of multiport type socket connector, be necessary existing technology is carried out design improved in fact, so that a kind of multiport type socket connector with anti-error assembling operation to be provided with video/audio.

Summary of the invention

Main purpose of the present utility model is to provide a kind of multiport type socket connector, wherein is provided with error-proof structure between the upper shield of several tubular protuberances of insulating body and fit, guarantees that the upper shield assembling is smooth smoothly, enhances productivity.

The utility model above-mentioned purpose and the technical scheme of dealing with problems are achieved in that this multiport type socket connector, and several the conducting terminals, an earthing member, several upper shields and several tubular shells that include insulating body, are mounted in the insulating body are formed.Wherein insulating body is provided with contact-making surface, be provided with several tubular protuberances in contact-making surface, front end outer ledge in each tubular protuberance is provided with at least two protuberances that are fan-shaped distribution, at least two protuberances each tubular protuberance front end the position difference is all arranged; Match the branch that has different colors at several upper shields of several tubular protuberances with it, the cover be covered with the tubular protuberance on the corresponding groove of at least two protuberances, described each upper shield groove location is provided with the protuberance position that is distributed on each tubular protuberance, so design, has anti-error assembling operation mistake, can guarantee that upper shield and insulating body assembling operation carry out smoothly, improve the quality of products.

The front end of described tubular protuberance is concaved with circular concave station, and opposite side is respectively equipped with the right angle projection in circular concave station edge; The upper shield of engaging tubular protuberance has the bulge loop that is complementary with circular concave station, and the relative right angle of bulge loop projection opposite side has square edge, makes upper shield be incorporated into the tubular protuberance and is not easy to rotation, fool proof effect when increasing assembling operation.

By last narration as can be known, the utility model multiport type socket connector and prior art multiport type socket connector advantage are obvious: have error-proof structure when the utility model multiport type socket connector upper shield and insulating body assembly, guarantee upper shield assembling operation order, anti-error assembling effect is obvious, reduce back processing procedure operation, improve the quality of products.
