Abstract

This invention relates to a structure of electric connector. It particularly relates to an electric connector with a top holding part for switching adjacent terminals for abutting and contacting in an insulating base. The electric connector comprises an insulating base, and a plurality of terminals. An insertion hole is formed inside the insulating base for being inserted with an external insertion terminal. The circumference of the insertion hole is built with an accommodation space with the top holding part. The accommodation space allows plural terminals to be inserted therein. Each terminal has a side formed thereon a contact part. The contact part of each terminal is extended into the top holding part inside the accommodation space. Each terminal close to the position of the insertion hole has a butt part extended into the insertion hole. Therefore, the insertion hole of the insulating base is inserted with the external terminal. The inserted terminal abuts upon the butt part of each terminal. Moreover, the contact part of the terminal with the butt part abuts upon the top holding part inside the accommodation space. Eventually, the top holding part abuts each of the adjacent terminals, it achieves the purpose of switching the electric conduction status between adjacent terminals.

Description

1254494 V. Technical Field of the Invention The present invention provides a purpose of electrically connecting a crying portion for switching adjacent terminals to abut the holding portion to abut the adjacent child electrical conduction state in the accommodating space. [Prior Art] Over-the-counter: The general electrical products are used to transmit the connection and signal transmission connection, and the electrical connection is turned on, and the interface of the intercommunication phase is connected with the host, and can be used as a mode; Cables and TV screens show various program images; as for the sound of the eve DVD player, the notebook computer, and the more complete sound = 5 · 1 channel, now there are 7: users Enjoy a better hearing effect, the source terminal is inserted into the connector, and the contact state of the connection is used to achieve the transmission of the sound source signal. The internal portion is provided with the insertion portion A 1 and the capacity $ is provided with the plurality of terminals B (see the first sub-sub The β 1 is electrically connected by the convex portion extension portion 1 2 1 of the abutting portion B 1 1 , and the elastic arm Β 2 2 is disposed at the 2 1 portion, and the insulator Β 2 3 is disposed, and the structure of the insulator is particularly The terminals of the electrical connection that are in contact with the insulated body connector can achieve various signals at the switching end, so as to connect the off-screen display, play the function, etc., and the sound of the sound channel. Action Part A 4, 5 parts Β 1 and the middle 'and B 2 3 At the time, the various electric signal signals can be used in the performance of the host, the multi-terminal end of the channel meter signal, the conventional 2, and the 2 and the middle terminal B elastic arm system are usually breathable products. For example, the electric screen on the TV screen, such as an electric speaker, in order to eliminate the original function, the transmission system will generate different electrical connector valleys A 2 ), and the outer terminal B 2 2 On extension B 2 2 - side terminal B 3

Page 5, 1254494 5. V. Inventive Note (2) The top holding portion B 3 1 is resisted, and the inner terminal B 3 is provided with an abutting portion B 3 2 for the external sound source terminal C to abut, that is, by the sound source terminal C is inserted into the insertion portion A 1 of the electrical connector A, and pushes the abutting portion B 3 2 of the inner terminal B 3 with the sound source terminal C so that the holding portion B 3 1 of the inner terminal B 3 holds the intermediate terminal B 2 The insulator B 2 3 and the abutting portion B 1 1 of the outer terminal B 1 are held by the insulator B 2 3 , and the convex portion B 1 2 of the outer terminal B 1 is separated from the extended portion B 2 1 of the intermediate terminal B 2 , that is, The insertion of the sound source terminal C is completed; however, when the conventional electrical connector A is used, there are still many defects, for example: I (1) the terminal B inside the electrical connector A, and the intermediate terminal B 2 must be made. The fork-shaped extension portion B 2 1 and the elastic arm B 2 2 are reworked to form the insulator B 2 3 at the end of the elastic arm B 2 2 , so that the intermediate terminal B 2 has a complicated process, is difficult, and has a poor product. Rate increase. (2) The intermediate terminal B 2 is formed as a bifurcated extension portion B 2 1 and an elastic arm B 2 2 , and the signal of the intermediate terminal B 2 is susceptible to bifurcation to form an unstable phenomenon, and the extension portion B 2 1 and the outer terminal B When the convex portion B 1 2 of the butting portion B 1 1 is in contact, it is easy to cause the transmission signal to be unstable and affect the quality of the transmission signal. (3) The intermediate terminal B 2 has a special structure, a complicated process, and must undergo two processing operations, and the increase in manufacturing cost is quite inconsistent with economic benefits. Therefore, how to solve the problems and shortcomings between the above-mentioned conventional electrical connectors and their terminals is the research of the relevant manufacturers engaged in this industry.
