Description

Memory card socket

Technical field

The utility model is relevant for a kind of memory card socket, be meant especially a kind of can be in order to pegging graft and withdraw from storage card, it can provide and function such as prevent to write, and produces and dress is organized memory card socket easily.

Background technology

See also Fig. 1 and Fig. 2, be a kind of known memory card socket, can be in order to peg graft and to withdraw from storage card, this memory card socket includes an insulating body 70 and a conducting terminal group 80, this insulating body 70 is made with plastic material, and this insulating body 70 has a top 71 and is connected in first arm 72, second arm 73 that these top 71 2 sides extend in parallel.Formation one is used to accommodate the accommodation space 74 of storage card between this top 71, first arm 72 and second arm 73, and this accommodation space 74 can supply storage card (as the SD card) to plant.Be formed with draw-in groove 75 in these accommodation space 74 2 sides in addition, can cooperate storage card two sides in order to clamping.

This conducting terminal group 80 is made up of plural conductive terminal 81, and these conducting terminals 81 are made with metal material, are installed on the top 71 of this insulating body 70, and extend in parallel with this first, second arm 72,73.When storage card is inserted in the accommodation space 74 of this insulating body 70, these conducting terminals 81 can be arranged at corresponding terminal on the storage card and form and electrically connect.These conducting terminal 81 other ends then extend outside the insulating body 70, can these conducting terminals 81 be formed with circuit board electrically connect in order to be welded on the circuit board.

To prevent the function that writes in order providing, to be fixed with a contact terminal 90 in addition on this insulating body 70, this contact terminal 90 has a body 91, and this body 91 connects and fixes in the 71 1 corresponding pickup grooves 76 of the top of insulating body 70.These body 91 1 sides extend to form the elastic arm 92 that a bending is " V " type, and this elastic arm 92 stretches into accommodation space 74 inside of insulating body 70.These body 91 rear ends extend to form an elongated extension 93, and offer a corresponding storage tank 77 on this insulating body 70, in order to ccontaining this extension 93.These extension 93 rear ends are also extended the pin portion 94 that has been bent to form downwards, can this contact terminal 90 be formed with circuit board electrically connect in order to be welded on the circuit board.

When the Control Component of storage card (figure slightly) but when switching to write-in functions, when storage card is inserted in this memory card socket, the elastic arm 92 of this contact terminal 90 can contact corresponding terminal on the storage card, make this two-terminal conducting, and signal is passed to circuit board, but make storage card become write state.

When the Control Component of storage card switches to when preventing write-in functions, when storage card is inserted in this memory card socket, the elastic arm 92 of this contact terminal 90 can not contact corresponding terminal on the storage card, make this two-terminal can't contact conducting, storage card is become prevent write state, reach with this and prevent the function that writes.

But, above-mentioned known memory card socket, the pin portion 94 of its contact terminal 90 is connected in extension 93 rear ends, when punching production, because of extension 93 is elongate, and the essential bending in rear end, the situation that can twist, so flatness control is difficult for, so quality is wayward.Moreover, on this insulating body 70, offer elongated storage tank 77, have and be difficult for to produce, be easy to generate burr, problem such as quality is wayward, cause produce and the dress group on greatly puzzlement.

The utility model content

Fundamental purpose of the present utility model, being to provide a kind of memory card socket, its contact terminal is when punching production, comparatively easily simple, the situation that can not twist, flatness control is easily, quality is more easy to control, and insulating body production is easy, and quality is controlled easily, so production and dress group are comparatively convenient.

In order to reach above-mentioned purpose, the utility model provides a kind of memory card socket, comprising: an insulating body, and it has an accommodation space that is used to accommodate storage card; One conducting terminal group is made up of the plural conductive terminal, and these conducting terminals are installed on this insulating body; And a contact terminal, it has a body, and this body is fixed on the insulating body, and this body one side has extended to form an elastic arm, and this elastic arm stretches into the accommodation space inside of insulating body, extends the pin portion that is formed with under this body one side direction.
