Abstract

The utility model relates to a grounded structure of a memory card inserting groove. The bottom of the inserting groove is provided with a groove seat; a coupling piece is matched and inserted in the groove seat; one side of one end of the coupling piece, which faces to an electric circuit, is convexly extended with a fixed length to be connected with a grounded line of the electric circuit; the other end of the coupling piece, which faces to the direction of a memory card, is convexly extended with a fixed length and is provided with a reflexed first coupling part; a metal shell clamped on the main body of the inserting groove is matched and provided with a grounded piece which extends between the first coupling part and the bottom of the inserting groove and has a fixed gap with the first coupling part. Thus, when the memory card is inserted by facing to the bottom of the inserting groove, the memory card can simultaneously press and touch the first coupling part of the coupling piece to be connected with the grounded piece; thus, electromagnetic wave is led in the metal shell from the grounded piece, and then, an earlap on the metal shell is conducted with a grounded line of the external electric circuit; thus, grounded role authentically forms; the purpose of preventing the interference of the electromagnetic wave is achieved.

Description

The ground structure of storage card slot

Technical field

The utility model provides a kind of ground structure of storage card slot, a kind of insertion that cooperates storage card particularly is provided, so that slot is had the ground structure of ground connection effect really, further to reach the effect that prevents Electromagnetic Interference by the ground connection effect of slot.

Background technology

Because electric circuit is when running, magnetic field in the electromagnetic environment that each circuit component constituted, electromagnetic wave will cause function frenzied, transmit mistake and the message condition of poor takes place, therefore in comparatively accurate electric circuit, how can cooperate the suitable demagnetization mechanism that imposes, to reduce the interference that electromagnetic wave was produced.

Again, generally the most common and the simplest demagnetization mechanism promptly is to utilize the ground connection effect to avoid forming in the circuit electromagnetic environment, when the laying of general electric circuit, can carry out setting of ground path in advance, to keep basic demagnetization mechanism; Moreover, when electric circuit need cooperate other to insert as during the extrapolation circuit use of storage card, it then must set firmly ground lug at the slot body of planting for storage card, is connect by ground lug and ground path, to reach the effect that the circuit of storage card is formed demagnetization mechanism again.

Yet the ground structure of known storage card slot is directly to be contacted with ground path by the mode of ground lug with a contact, and it is limited that it not only couples effect, and break away from because of slight vibrations easily, can't constitute the effect of ground connection really.

Technology contents

The fundamental purpose of the ground structure of a kind of storage card slot of the utility model, provide a kind of insertion that cooperates storage card, so that slot is had the ground structure of ground connection effect really, further to reach the effect that prevents Electromagnetic Interference by the ground connection effect of slot.

The technical solution of the utility model is: a kind of ground structure of storage card slot, it is to be provided with in its bottom to be used for the jack that the confession terminal plugs that the basic structure of its slot is formed, and on its main body, be installed with and be used for connecting storage card is formed the ground lug of demagnetizing action, wherein with the ground path of electric circuit:

The bottom of this slot is provided with the groove seat, this groove seat be by with the corresponding side of storage card connect to the corresponding side of electric circuit, and be engaged in the groove seat and plug coupling, one end of this coupling is that the side towards electric circuit protrudes out a regular length and connects with the ground path of electric circuit, and the other end of this coupling then protrudes out a regular length and is provided with first couplings of reflexed towards the direction of storage card; Again, this metal shell then cooperates and is provided with between the bottom that ground lug stretches into first couplings and slot, and has a fixing gap with first couplings, with when storage card inserts towards the bottom of slot, storage card can press first couplings of touching coupling to engage with ground lug simultaneously, makes electromagnetic wave import metal shell by ground lug, again by auricular concha on the metal shell and outside electric circuit ground path conducting, really form the ground connection effect, prevent Electromagnetic Interference to reach.

Embodiment

For the clear structure of the present utility model of your auditor is formed, and the overall operation mode, cooperate graphic being described as follows now:

The ground structure of the utility model storage card slot, the basic structure of its slot is formed as shown in Figure 1, be to be provided with jack 11 in its bottom, for plugging of terminal 12, and on its main body, be installed with a metal shell 30 in order to connect with the ground path of formation, so that storage card M is formed demagnetizing action with the external electrical circuit with ground lug 31 and auricular concha 32.

Please cooperate simultaneously with reference to Fig. 2, Fig. 3, Fig. 5 and shown in Figure 6, its slot 10 is to be provided with a groove seat 13 in addition in the bottom, its groove seat 13 be by with the corresponding side of storage card connect to the corresponding side of electric circuit, and be engaged in and plug a coupling 20 in the groove seat 13, one end of its coupling 20 is that the side towards electric circuit protrudes out a regular length and connects with the ground path of electric circuit, and the other end then protrudes out a regular length and is provided with first couplings 21 of a reflexed towards the direction of storage card M; Again, its clamping is provided with between the bottom that a ground lug 31 stretches into first couplings 21 and slot 10 in 30 cooperations of the metal shell on slot 10 main bodys, and has a fixing gap with first couplings 21.

As shown in Figure 4, with when storage card M inserts towards the bottom of slot 10 2, storage card M can press first couplings 21 of touching coupling 20 to engage with ground lug 31 simultaneously, make electromagnetic wave import metal shell 30 by ground lug 31, again by auricular concha on the metal shell 32 and outside electric circuit ground path conducting, really form the ground connection effect, prevent Electromagnetic Interference to reach.
