Abstract

The utility model relates to an improved structure of a card connector, which is used for splicing an electronic card. The card connector is composed of an insulator, a plurality of first terminals, a plurality of second terminals and a rotary body, wherein a plurality of first terminals and a plurality of second terminals which are arranged in a staggered way are arranged in the terminal caulking groove of the insulator, the rotary body is pivotally arranged behind the insulator, and can be rotated behind the insulator, when the rotary body is rotated downward, one end of the rotary body causes the rear end of the first contact part of the first terminals to be jacked up, and the abutting end of the first contact part generates power for pressing downward, so as to ensure the electronic card to be stably propped through the first contact part, therefore, not only fixed arms are not required to be integrally molded on the two side edges of the insulator, but also ear clip devices are also not required to be assembled on the two side edges of the insulator, the manufacture procedure can be simplified, the manufacturing cost and the assembly cost can be reduced, and the operation is more convenient.

Description

The structural improvement of card connector

Technical field

The utility model relates to a kind of structural improvement of card connector, is meant a kind of structural improvement that makes the first terminal firmly be held in the card connector on the electronic cards especially.

Background technology

The part of the internal memory on the computer main frame panel is used the DDR connector, use to provide electronic cards to peg graft, generally speaking, the DDR connector has an insulating body, dual-side at this insulating body can extend a pair of ear clip device forward, by this firm clamping of electronic cards that ear clip device will be inserted on the insulating body is located.

The structure of aforementioned ear clip device is formed by the forwards integrally formed fixed arm of the dual-side of insulating body usually, utilize the dual-side of the fixed arm deduction of dual-side in electronic cards, with with the electronic cards strong fix, but this fixed arm structure is easy-formation more not when making insulating body not only, and also is easy to distortion or fracture in the use.There is a kind of ear clip device to be assembled in the dual-side of insulating body in addition again, with the assembly of this insulating body for separating separately, ear clip device is hubbed on the dual-side of insulating body by this, but make ear clip device elasticity rotate and be clipped on the dual-side of electronic cards, but this complex structure is difficult for assembling again, not only cause manufacturing cost to promote, and this ear clip device also is easy to be got loose by assembling place in use, and then can't reaches the effect of expection.

To how address the above problem and lack, become the relevant manufacturer that is engaged in the industry the research direction place of improving competitively.

Summary of the invention

The designer collects related data because above-mentioned every problem and disappearance, through assessing in many ways and consider, and to engage in the many years of experience of the industry accumulation, through constantly studying and revising, designs the structure improved novel patent of this card connector.

The purpose of this utility model is to provide a kind of structural improvement of card connector, by improvement of the present utility model, utilizes a rotary body to promote the first terminal and produces the strength that presses down, and makes the electronic cards that supports that the first terminal can be firm, so that electronic cards is located.

The purpose of this utility model is to provide a kind of structural improvement of card connector, and by improvement of the present utility model, making the utility model that ear clip device need be set can be with the firm clamping of electronic cards location.

For realizing the described purpose in prostatitis, the utility model provides a kind of structural improvement of card connector, an electronic cards is used for pegging graft, this card connector is by an insulating body, the plural number the first terminal, plural number second terminal and a rotary body are formed, this plural number the first terminal and plural second terminal are staggered in the terminal caulking groove that is arranged at insulating body, this rotary body is hubbed on the rear of insulating body, rotary body can be rotated at the rear of insulating body, when rotary body rotates, the one end can be with the rear end jack-up of first contact site of the first terminal, make the butt end of first contact site produce the strength that compresses downwards, electronic cards is firmly supported to make first contact site.

The utlity model has following beneficial effect: utilize the insulating body rear rotary body that is pivoted, make this rotary body when pressing down, the pushing and pressing end of rotary body can produce the upwards strength of jack-up to the first contact site rear end of the first terminal, the front end of first contact site is supported downwards, can firmly support a side in electronic cards, make a side of electronic cards be able to strong fix, and then not only need not at the one-body molded fixed arm of insulating body dual-side, also not be used in insulating body dual-side installing ear clip device, can simplify processing procedure and can reduce the manufacturing assembly cost again, and have more convenience on using.
