Abstract

A socket configuration of a memory card is a socket consisting of a rubber base equipped with a metal shell. The rubber base is equipped with a slot, and the back of the slot is equipped with a plurality of terminals and a conductive terminal. The metal shell is provided with a conductive finger. The memory card is inserted into the slot. The terminals contact a connecting port of the memory card and push and press the conductive finger to make the finger be in conductive connection with the conductive terminal by contacting. An elastic arm is arranged inside the slot of the rubber base, and the tail end of the elastic arm is equipped with a projecting point. The conductive finger of the metal shell relies on the back of the elastic arm. The elastic fatigue of the conductive finger is reduced via the elastic arm.

Description

The socket structure of memory card

Technical field

The utility model relates to the socket structure of memory card, especially a kind of socket in order to the plug-in mounting memory card of finger is made up of rubber base and metal shell, be provided with an elastic arm in the rubber base, make the electroconductive elastic sheet of metal shell must lean against the rear of elastic arm, reduce the elastic fatigue of electroconductive elastic sheet by elastic arm.

Background technology

As everyone knows, general digital still camera or electronic dictionary, it must use memory card to store data usually, so on digital still camera or electronic dictionary, be equiped with a socket, memory card is inserted in the socket, digital still camera is stored in image data in the memory card, or electronic dictionary is read the data of memory card.

Tradition is in order to the socket of plug-in mounting memory card, as Fig. 4 and shown in Figure 5, go up installing one metal shell a2 by a rubber base a1 and form a socket a, be provided with a slot space a11 in this rubber base a1, and be equiped with most terminal b and a conducting terminal c at a11 rear, slot space, has an electroconductive elastic sheet a21 on the metal shell a2, memory card d is inserted slot space a11, make the Port (not expression in graphic) of terminal b contact memory card d, and pushing electroconductive elastic sheet a21, make it contact conducting, to read or to store with conducting terminal c.Its major defect is:

The electroconductive elastic sheet a21 of the metal shell a2 of conventional socket a only passes through the elastic recoil of material itself, and the very thin thickness of electroconductive elastic sheet a21, it in use for some time, be easy to generate elastic fatigue, make that electroconductive elastic sheet a21 can't return, cause in the operation of digital still camera or electronic dictionary and be easy to generate wrong signal.

Summary of the invention

The inventor carries out research idea at above-mentioned defective, creates the technical solution of the utility model eventually.

Main purpose of the present utility model provides a kind of socket structure of memory card, socket is made up of rubber base and metal shell, be provided with an elastic arm in the rubber base, make the electroconductive elastic sheet of metal shell lean against the rear of elastic arm, reach the purpose that reduces the elastic fatigue of electroconductive elastic sheet by elastic arm.

The purpose of this utility model is achieved in that a kind of socket structure of memory card, by installing the socket that metal shell is formed on the rubber base, this rubber base is provided with a slot space, be equiped with most terminals and a conducting terminal at rear, slot space, has an electroconductive elastic sheet on this metal shell, this memory card inserts the slot space, the Port of this termination contact memory card, and the pushing electroconductive elastic sheet makes it contact conducting with conducting terminal, it is characterized in that: be provided with an elastic arm in the slot space of this rubber base, this elastic arm is not held has a salient point, and the electroconductive elastic sheet of this metal shell leans against the rear of this elastic arm.

Further specify below in conjunction with preferred embodiment and accompanying drawing.

Embodiment

Consult Fig. 1-shown in Figure 3, the utility model is formed a socket 1 by installing one metal shell 12 on the rubber base 11, be provided with a slot space 11a in this rubber base 11, and be equiped with most terminals 2 and a conducting terminal 3 at 11a rear, slot space, and has an electroconductive elastic sheet 12a on this metal shell 12, memory card 4 is inserted slot space 11a, make the Port (not expression in graphic) of terminal 2 contact memory cards 4, and pushing electroconductive elastic sheet 12a, make it contact conducting with conducting terminal 3, to read or to store, as shown in Figure 3, it is characterized in that: be provided with an elastic arm 11b in the slot space 11a of this rubber base 11, have a salient point 11c in this elastic arm 11b end, the electroconductive elastic sheet 12a of this metal shell 12 leans against the rear of elastic arm 11b, reduces the elastic fatigue of electroconductive elastic sheet 12a by elastic arm 11b.

According to above-mentioned structure, when memory card 4 inserts in the slot space 11a of rubber bases 11, this memory card 4 can push elastic arm 11b and electroconductive elastic sheet 12a simultaneously, make this electroconductive elastic sheet 12a contact conducting with conducting terminal 3, so get final product turning circuit, make digital still camera or electronic dictionary read actions such as data, storage or deletion.

Because the electroconductive elastic sheet 12a of this metal shell 12 is the elastic arm 11b rears that lean against in the slot space 11a that is located at rubber base 11, increase the intensity of electroconductive elastic sheet 12a by this elastic arm 11b, the electroconductive elastic sheet 12a that so can reduce metal shell 12 produces elastic fatigue, increase the service life, to avoid this electroconductive elastic sheet 12a can't return, cause the operation of digital still camera or electronic dictionary to go up the situation that produces wrong signal because of elastic fatigue.

Comprehensive the above, the disclosed structure of the utility model is in the past not have, and can reach above-mentioned effect really, has novelty, creativeness and practicality.

Claims

1, a kind of socket of memory card structure, by installing the socket that metal shell is formed on the rubber base, this rubber base is provided with a slot space, be equiped with most terminals and a conducting terminal at rear, slot space, has an electroconductive elastic sheet on this metal shell, this memory card inserts the slot space, the Port of this termination contact memory card, and the pushing electroconductive elastic sheet makes it contact conducting with conducting terminal, it is characterized in that: be provided with an elastic arm in the slot space of this rubber base, this elastic arm is not held has a salient point, and the electroconductive elastic sheet of this metal shell leans against the rear of this elastic arm.
