Description

Card connector with anti-static function

technical field

The utility model relates to a memory card connector in an electronic device, in particular to a card connector with an antistatic function.

Background technique

Existing anti-static card connectors, such as Taiwan Patent No. M273,783, disclose an anti-static electronic card connector. This case is mainly based on an electronic frame, which has an upper frame portion, which is used for grounding when the electronic card is inserted, so that the static electricity on the electronic card is directly guided to the ground by the electronic frame when it is inserted, so as not to It will cause damage to the electronic device connected to the electronic card connector.

However, the design of the above case does not completely prevent damage that may be caused by static electricity. The reason is that there are several terminal ends below the card entrance at the front of the connector for connecting to the circuit board. When the electronic card is inserted, the static electricity it has has a chance to conduct with the terminal ends below. And cause damage to other electronic components through the terminal.

Contents of the invention

The main purpose of the present invention is to provide a card connector with anti-static function, which can achieve the effect of preventing static electricity both above and below the opening.

In order to achieve the aforementioned purpose, a card connector with anti-static function provided by the present invention includes: a base made of insulating material; a cover made of conductive material placed above the base, the After the cover body is combined with the base, an opening is formed at the front end, and at least one card insertion space is formed inside, which can be used for inserting a card from the outside; and several terminals are arranged on the base and located in the card insertion space; , the front edge of the base has a grounding piece extending laterally, the grounding piece is made of conductive material and is located below the opening. In this way, the effect of completely preventing static electricity can be achieved.

Detailed ways

In order to describe the structure and characteristics of the present utility model in detail, the following preferred embodiment is given and described as follows in conjunction with the accompanying drawings, wherein:

As shown in Figure 1, a card connector 10 with antistatic function provided by the first preferred embodiment of the present invention is mainly composed of a base 11, a cover 21, and several terminals 31, wherein :

The base 11 is made of insulating material.

The cover 21 is made of conductive material and is covered above the base 11. After the cover 21 is combined with the base 11, an opening 22 is formed at the front end, and at least one card insertion space 24 is formed inside for external insertion. A card (not shown in the figure).

The terminals 31 are disposed on the base 11 and located in the card insertion space 24 .

A grounding element 26 is located at the front edge of the base 11 and extends laterally along the front of the base 11 . The grounding element 26 is made of conductive material and is located below the opening 22 . The grounding member 26 has a top surface 261 and a front surface 262 , the longitudinal section of which is roughly L-shaped. The top surface 261 and the front surface 262 respectively cover the top and the front of the front edge of the base 11 . Moreover, among the terminals 31 , one end of some terminals 31 extends to the front edge of the base 11 , is located below the grounding member 26 , and is separated from the grounding member 26 by a predetermined distance without touching each other. The left and right ends of the grounding member 26 further extend an extension arm 28 to the rear respectively. 26, so the static electricity on the grounding member 26 can be led out directly.

In this embodiment, the ground member 26 and the cover 21 are integrally bent and formed.

The actuation mode of the present utility model is described as follows:

When inserting a card, since the cover 21 above the opening 22 and the grounding member 26 below the opening 22 are both conductive materials, when the card is inserted, no matter whether it touches the upper cover 21 or the lower grounding member 26, the The static electricity on the card will be guided and grounded, thereby effectively preventing the static electricity on the card from causing damage to the electronic components or devices externally connected to the connector 10 of the present invention. Also, since the terminals 31 and the grounding piece 26 are separated by a predetermined distance and are not in contact with each other, the terminals 31 are protected by the grounding piece 26 and will not contact the inserted card, further avoiding the electrostatic conduction on the card. to the terminals 31.

Please refer to Fig. 2 again, a card connector 10' with anti-static function provided by the second preferred embodiment of the present invention is mainly similar to the first embodiment disclosed above, the difference is that:

The ground member 26' is formed by the cover 21' extending outward for a predetermined length in front of the base 11' to form the top surface 261'.

In this way, when the card is inserted, before entering the opening 22', it will first contact the grounding member 26' to form a conductive grounding effect.

The rest of the structure and operating state of the second embodiment are the same as those of the first embodiment disclosed above, and will not be repeated here.

Please refer to Fig. 3 to Fig. 4 again. The third preferred embodiment of the present invention provides a card connector 40 with anti-static function, which is basically the same as the first embodiment disclosed above, except that:

The grounding piece 26 ″ and the cover 21 ″ are two different components, and the two sides of the grounding piece 26 ″ respectively extend upwards with a connecting arm 263 ″, which is connected to both sides of the cover 21 ″. In this embodiment, The connecting arms 263" on both sides of the grounding member 26" are pivotally connected to the cover 21" in a swingable manner. Fig. 4 shows the state that the grounding member 26" is turned up.

In this way, the effect of grounding and anti-static can also be achieved by the cover 21 ″ above the opening 22 ″ and the grounding piece 26 ″ below the opening 22 ″. In addition, the connecting arm 263" of the third embodiment can also be used as an extension arm like the first embodiment, which also has the functions of convenient connection with external wires and good grounding effect. The operation mode of this embodiment is generally the same as The first embodiment is disclosed above, so it is not repeated here.

It can be known from the above three embodiments that the technical feature of the present invention is that a grounding member 26 is provided below the opening 22 and matched with the cover 21 above the opening 22 . This kind of structure forms a complete grounding mechanism, so that when the card is inserted, it will inevitably contact the grounding member 26 or the cover 21, and the static electricity on the card can be grounded, and the static electricity will not be conducted to the terminal 31, thereby protecting the connector. connected electronic devices or components.
