Description

The mini jack connector

Technical field

The utility model relates to a kind of mini jack connector, refers in particular to a kind ofly to utilize the special construction of terminal and can make terminal with the firm socket connector that connects of insulating body.

Background technology

DC power connector on the Mobile Communications product is widely used, almost is the indispensable part of each action mobile phone, and its major function is to provide the transmission of power supply between two systems.In recent years, along with mobile phone constantly develops towards frivolous small direction, supporting with it connector is constantly miniaturization also, this design is owing to the restriction that dwindled by assembly or the space reduces, will certainly cause the fatigue resistance of assembly relatively to weaken, the test request that must surpass 1.5kg for the retain strength (RetentionForce) that satisfies the conducting terminal of formulating, and prevent the bad phenomenon that the terminal that occurs in the long-term use is loosening, up to now, such connector roughly has two kinds of structures: one is interfered fixing from the perforate of insulating body back with the punching out terminal.It is two from the perforate of insulating body back, fix with another sheet punching out terminal of car system terminal riveted, more than two series products designs can be respectively with reference to United States Patent (USP) No. 6322297 (as shown in Figure 1) and No. 5927999 cases such as (as shown in Figure 2), this two case has the representativeness of distinct prior art.

First kind of structure that above-mentioned patent disclosed, back perforate from insulating body, because of considering the stability of terminal, enough accommodation spaces must be arranged in the insulating body and interfere the space, therefore insulating body need design bigger volume, like this, be unfavorable for the development of product trend toward miniaturization, simultaneously, when conducting terminal is being subjected to external force and inserts,, its inside interferes the fixedly precautionary measures though having, but the opposite direction stressed at conducting terminal is not provided with anti-unloading device, therefore get loose easily, be not easy, will certainly occur the loosening bad phenomenon of terminal in the long-term use by standard testing; And second kind of structure from the perforate of insulating body back, fixed with another sheet punching out terminal of car system terminal riveted, this kind structure more complicated, and cost is higher, has improved the processing procedure difficulty especially, is unfavorable for the cost competition.

Because traditional connector exists above-mentioned shortcoming, the utility model spy provides a kind of can reduce the space, can improve the steadiness of product again, but also can simplify production process, cost-effective creation, it is to be provided with retaining wall by the back with insulating body, and insulating body and terminal be respectively equipped with draw-in groove and stuck point, and fixing shell fragment and earth terminal are that the matching design of Construction integration realizes.

The utility model content

Main purpose of the present utility model is to provide a kind of mini jack connector, and it utilizes insulating body to be provided with the draw-in groove and the stuck point of response, and is firm trivial fixed with the stuck point multiple spot on the conducting terminal, makes it can meet the testing standard requirement of retain strength.

Another purpose of the present utility model is to provide a kind of mini jack connector, and it utilizes the cooperation of insulating body and terminal, thereby avoids terminal to interfere fixing institute to take up space mutually, thereby satisfies the requirement of miniaturization.

Another purpose of the present utility model is to provide a kind of mini jack connector, it utilizes the design of the back retaining wall of insulating body to replace production process with the fixing complexity of another sheet punching out terminal of car system terminal riveted, thereby reach the simplification procedure for producing, save production cost.

For reaching above-mentioned purpose, embodiment of the present utility model is: a kind of mini jack connector construction is provided, this structure comprises shielding casing, insulating body, conducting terminal and switched terminal, with the insulating body is main part, its design has draw-in groove and the stuck point that cooperates with terminal, fixing shell fragment and earth terminal design for one simultaneously, and its back design has one to be used for stopping the retaining wall that conducting terminal is given up the throne.By adopting such scheme, the conducting terminal that the utility model has overcome because of caused by insertion force moves the position, has improved the steadiness of product, meets the test specification requirement of retain strength, avoid terminal to interfere fixing institute to take up space mutually simultaneously, thereby satisfy the requirement of miniaturization.And it utilizes the design of the back retaining wall of insulating body to replace production process with the fixing complexity of another sheet punching out terminal of car system terminal riveted, thereby reaches the simplification procedure for producing, has saved production cost.
