Description

Electronic card coupler

[technical field]

The utility model is about a kind of electric connector, particularly about a kind of electric connector that connects electronic cards.

[background technology]

The employed electronic cards of computer has Multi Media Card or memory card, at present memory card on the market has plurality of specifications such as Secure Digital Card (being called for short SDC), MutiMedia Card (being called for short MMC), Smart Media Card (being called for short SMC), Memory Stick Card (being called for short MSC), Compact Flash Card (being called for short CFC) or the like, because the memory khaki connecting point position of each specification is neither together, so the electric connector that the required cooperation of the memory card of different size is pegged graft is then inequality.

In order to reach the convenience in the use, the manufacturer all tries every possible means and the electric connector of various different kenels is integrated into a kind of electric connector of memory card use of applicable several specifications.

MSC has two kinds of different sizes of size at present, hereinafter to be referred as kilocalorie and lesser calorie, kilocalorie is thick and wide than lesser calorie, yet an end of kilocalorie and lesser calorie is respectively equipped with the contact of aligned identical, early stage MSC is kilocalorie, developed again afterwards and lesser calorie, so early stage connector is to design to have to stablize fastening kilocalorie person, so, lesser calorie then connects by an adapter at present, and adapter is identical with kilocalorie size rule, and lesser calorie can be inserted and be inserted the connector connection in the adapter again, at present adapter is to be provided with a metal top cover and a plastic cement base that is ㄇ shape (or can be described as " door " font), and lower edge slightly past inner bending in metal top cover both sides is closed to collude with the plastic cement base.

See also Fig. 1, be existing electronic card coupler, it is provided with a pedestal 10 and three row's terminals 20, wherein:

This pedestal 10 is to include a front stall 11, a back seat 12 and a loam cake 14, this loam cake 14 is to be covered on front stall 11 and the back seat 12, the draw-in groove 13 that is provided with several different in width or height in this pedestal and has sharing space can insert the location so as to the electronic cards that makes different size.

This three rows terminal 20 is that a row is located at front stall 11, two rows are located at back seat 12, each terminal is provided with an elastic arm 21, elastic arm 21 is provided with a contact 22 that protrudes near end, row's terminal right side outermost terminal of wherein being located at front stall 11 is a terminal 25, adjacent with terminal 25 is terminal 26, the contact 21 of terminal 26 and the contact 21 of terminal 25 be stagger before and after being and about stagger; When an electronic cards like this is inserted, a contact of this electronic cards can first contact terminal 26 contact terminal 25 again.

Because the contact 21 of terminal 25 is positioned at the outside of the contact 21 of terminal 26, so when adapter inserted, the metal top cover one side lower edge of adapter can touch the contact 21 of this terminal 25 and form short circuit.

[utility model content]

The purpose of this utility model is to provide a kind of electronic card coupler, can prevent that when adapter inserts the metal top cover one side lower edge of adapter from touching terminal and forming short circuit.

For reaching above-mentioned purpose, the utility model electronic card coupler includes: a pedestal, be provided with at least one draw-in groove in it, but this draw-in groove fastening one electronic cards, the front end of this pedestal is provided with the insertion mouth of this draw-in groove; And at least one row's terminal, this each terminal is provided with an elastic arm, and this elastic arm is provided with a contact that protrudes so as to being electrically connected with this electronic cards near end; It is characterized in that, be the first terminal wherein near a side outermost terminal of row's terminal of the insertion mouth of this draw-in groove, the inboard terminals of adjacent of this first terminal is second terminal, the elastic arm of this first terminal is to extend to the inside to make contact be positioned at the contact rear of second terminal, and the contact of the contact of this first terminal and second terminal staggers and forms overlapping at X-axis coordinate (left and right directions) at Y-axis coordinate (fore-and-aft direction).

By above structure, because the elastic arm of this first terminal is to extend the contact that makes the contact and second terminal to the inside to form almost completely overlapping at the X-axis coordinate, the contact of the first terminal at the contact of the X-axis coordinate and second terminal in same position, when so adapter inserted, the metal top cover one side lower edge of adapter can not touch the contact of the first terminal and form short circuit.

Above-mentioned and other purpose of the present utility model, advantage and characteristic by in the detailed description of following preferred embodiment and with reference to graphic when can be clearer, wherein:

[embodiment]

See also Fig. 2 and Fig. 3, present embodiment is to be provided with a pedestal 30 and three row's terminals 40, wherein:

This pedestal is to include a front stall 31, a back seat 32 and a loam cake 34, this front stall 31 and back seat 32 are all to be provided with a fixture block 35 for plastic cement material and both sides, this loam cake 34 is for respectively being provided with a hole clipping 36 before and after metal material and the both sides, this loam cake 34 is to be covered on front stall 31 and the back seat 32, the hole clipping 36 of loam cake and fixture block 35 fastenings of front stall 31 and back seat 32, the draw-in groove 33 that is provided with several different in width or height in this pedestal and has sharing space, can insert the location so as to the electronic cards that makes different size, the front end of pedestal is provided with the insertion mouth 37 of draw-in groove 33.

This three rows terminal 40 is that a row is located at front stall 31, two rows are located at back seat 32, each terminal is provided with an elastic arm 41, elastic arm 41 is provided with a contact 42 that protrudes near end, wherein being located at front stall 31 is the first terminal 45 near row's terminal right side outermost terminal of the insertion mouth 37 of this draw-in groove, the inboard terminals of adjacent of the first terminal 45 is second terminal 46, the elastic arm 41 of this first terminal 45 be to the inside gradually diagonally extending make contact 42 be positioned at contact 42 dead asterns of second terminal 46, promptly the contact 42 of the contact 42 of this first terminal 45 and second terminal 46 staggers and forms almost completely overlapping at X-axis coordinate (left and right directions) at Y-axis coordinate (fore-and-aft direction).

By above structure, the contact 42 of second terminal 46 is to be front and back to stagger with the contact 42 of the first terminal 45; See also Fig. 4, when an electronic cards 50 was inserted, the contact 42 that a contact of this electronic cards can first contact terminal 46 is the contact 42 of contact terminal 45 again.

Moreover, because the elastic arm 41 of this first terminal 45 is to extend the contact 42 that makes the contact 42 and second terminal 46 to the inside to form almost completely overlapping at the X-axis coordinate, the contact 42 of the first terminal 45 at the contact 42 of the X-axis coordinate and second terminal 46 in same position, when so adapter inserted, the metal top cover one side lower edge of adapter can not touch the contact 42 of the first terminal 45 and form short circuit.

See also Fig. 5, be to be the utility model second embodiment, it is roughly identical with first embodiment, and its difference is that the elastic arm 41 of this first terminal 45 is directly to extend back earlier not tilt to the inside, and extends the contact 42 of this protrusion near terminal bending to the inside in elastic arm.

The specific embodiment that is proposed in the detailed description of preferred embodiment is only in order to be easy to illustrate technology contents of the present utility model, and be not with the utility model narrow sense be limited to this embodiment.
