Electric connector

[technical field]

The utility model is about a kind of electric connector, particularly links the electric connector of fixing all terminals earlier about a kind of combination that utilizes.

[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), Muti Media Card (being called for short MMC), SmartMedia 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, can block shared electronic card coupler more and then need design many row's terminals cooperation electrical connections.

See also Fig. 1, be a kind of electronic card coupler that connects SDC, it includes a pedestal and row's terminal 20, wherein:

This pedestal includes a plastic cement base 10 and a metal top cover 18, and this metal top cover 18 is covered on to make on this plastic cement base 10 and forms a draw-in groove 11 in the pedestal, and these these plastic cement base 11 bottom surface zone lines are provided with a hollow slots 12.

This row terminal 20 is and plastic cement base 10 ejection formation together that the fixed part of each terminal be these plastic cement base 10 encapsulation coatings.

The above-mentioned existing following shortcoming that is configured with: 1. whole row's terminal 20 and whole plastic cement base 10 be ejection formation together, comparatively inconvenience in the manufacturing, 2. be somebody's turn to do the essential very big hollow slots 12 of an area that forms in zone that whole row's terminal 20 extends to this plastic cement base 10, so can not interfere with this whole row's terminal by plastic rubber ejaculate molding, yet the structural strength of plastic cement base 10 is died down.

[utility model content]

Main purpose of the present utility model is to provide a kind of electric connector, and it is to utilize a simple combination earlier in conjunction with all terminals, does the fit assembling with pedestal again and gets final product, and reaches comparatively easy in the manufacturing.

For reaching above-mentioned purpose, the utility model electric connector includes: a pedestal, be provided with a link slot in it, and this link slot is provided with an inlet, and the one end is provided with an assembling grove; And a combination, but its fit is fixed in the assembling grove of this pedestal; And a plurality of terminals, each terminal is provided with a fixed part, this fixed part one end is provided with an extension, this fixed part other end is provided with a pin portion, this extension is provided with a contact site near end, the fixed part of these a plurality of terminals is spaced and is fixed in this combination, and when this combination fit was fixed in the assembling grove of this pedestal, the contact site of this each terminal was in the link slot of this pedestal.

The beneficial effects of the utility model are:

1. utilize a simple combination earlier in conjunction with all terminals, do the fit assembling with pedestal again and get final product, the together ejection formation of whole pedestal and all terminal that do not need like this, comparatively easy in the manufacturing.

2. because pedestal is not together to penetrate with all terminals, so the pedestal bottom surface does not need whole hollow out, pedestal intensity is preferable.

3. if when on making, defective products being arranged, do not need whole the calcellation, visual pedestal or combination what the person is bad changes.
