Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a connector detaching mechanism used for detaching a circuit board from a connector.

[Prior Art] Conventionally, as an example of a circuit board, a connection device used for connecting an IC card is shown in FIG. The connecting device shown in FIG. 9 is used for connecting the IC card 1 and has a small box 3.

At the end of the IC card 1, a plurality of conductive socket contacts 5 are installed. Inside the box body 3, a connector 9 having a plurality of conductive pin contacts 7 is provided. The socket contacts 5 of the IC card 1 are connected to these pin contacts 7 one to one. An elongated hole 11 for inserting the IC card 1 is formed on the upper surface of the box 3. Now, when the IC card 1 is inserted into the elongated hole 11 of the box body 3 from the tip of the socket contact 5, the socket contact 5 is fitted into the bin contact 7 of the insulator 9. This state is shown in FIG. At this time, IC card 1 shows arrow A
The socket contact 5 is pushed in the direction, and the socket contact 5 is pressed against the pin contact 7 with a strong force for fitting.
The IC card 1 can be removed by pulling it upward from the box 3.

[Problems to be solved by the invention] However, when the box body 3 is small and light, when the IC card 1 is pulled out as shown in FIG. 11, the box body 3 is lifted upward as shown by an arrow B. Will end up.

Moreover, even if the box 3 is not lifted up, the box 3 that is placed neatly is moved, or as shown in FIG. 12,
If the IC card 1 is removed while twisting, the connector 9 inside the box body 3 may be damaged.

Therefore, an object of the present invention is to provide a connector disconnection mechanism that can easily disconnect the circuit board without any trouble.

[Means for Solving the Problems] According to the present invention, in a mechanism for detaching a circuit board inserted into and connected to a connector from the connector, symmetrical pairs of connectors are rotatably attached to both ends of the connector. Each of the pair of covers, facing each other at a side end parallel to the insertion direction of the circuit board inserted and connected to the connector with a space therebetween, with the rotation in a direction to expand or contract the space. An operating lever to be moved; a projection that faces the connection end of the circuit board and presses the connection end in accordance with the movement of the operation lever toward the side end; and a guide portion that guides the insertion of the circuit board. A disconnecting mechanism of the connector is obtained.

[Operation] To detach the circuit board from the connector, the lever is operated to rotate the cover in a predetermined direction, and the protrusion of the cover is pressed against the connection end of the circuit board. When the cover is further rotated in the same direction, the protrusion pushes the circuit board out of the connector. Subsequently, the lever is attached to the side edge of the circuit board, thereby suppressing the circuit board from popping out. The insertion of the circuit board into the connector is guided by the guide portion provided on the cover.

[Embodiment] FIGS. 1 and 2 show a connector for an IC card having a release mechanism according to an embodiment of the present invention.

The illustrated disengagement mechanism has a pair of covers 24 associated with the insulator 22 of the connector 20.

On the upper side of the lateral plate 26 of the insulator 22, a plurality of conductive bin contacts 28 are provided as clearly shown in FIGS. Side plates 31 are formed on both ends of the insulator 22, respectively. A hole 35 for the central axis of rotation is formed in these side plates 31.

Referring to FIGS. 5 to 8 as well, the cover 24 is formed with a hole 33 facing the hole 35 of the side plate 31 and a protrusion 39. cover
An operating lever 41 is formed on the upper portion of 24. lever
41 is located away from hole 33. Below the lever 41, a guide portion, that is, a guide plate 45 is formed to guide insertion of a circuit board, for example, an IC card 43.

The two covers 24 are attached to each other so as to sandwich the side plate 31 of the insulator 22. That is, the hole 35 of the one cover 24 is opposed to the hole 35 of the one side plate 31, the hole 33 of the other cover 24 is opposed to the hole 35 of the other side plate 31, and these holes 33, 35 are Insert the shaft pin. As a result, each hole 35 for the insulator 22, that is,
The cover 24 can swing around the shaft pin.

Further, a mutual space equal to the plate thickness of the insulator 22 is formed between the covers 24.

In the state shown in FIG. 2, when the IC card 43 is inserted while being guided by the guide plate 45, the tip end surface of the IC card 43 contacts the protrusion 39. Push in the IC card 43 and the protrusion 39 will
The card 43 is pushed by the front end surface of the card 43 and fitted into the groove 37. At the same time, a socket contact (not shown) of the IC card 43 is connected to the bin contact 28 provided on the lateral plate 26 of the insulator 22 to make an electrical connection. In this state, as can be seen from the structure of the cover 24, the side edge parallel to the insertion / removal direction of the IC card 43 and the lever 41 face each other with a gap.

Next, the detaching operation will be described.

First, when a force is applied to the lever 41 in the directions toward each other as shown by an arrow c in FIGS. 1 and 2, the entire cover 24 has a hole 35.
And the protrusion 39 applies a force to the IC card 43 in the detaching direction. That is, the IC card 43 is pushed upward by the rise of the protrusion 39. With this, the fitted state is released. Following this, each lever 41 is pressed against the above-mentioned side edge of the IC card 43, and as a result, the two levers 4 of the IC card 43 are pushed.
It will be sandwiched between 1. Therefore, there is no danger of the IC card 43 popping out and falling due to the momentum of removal.

The IC card 43 remains in the connector 20 after that, but since the contact 28 is not fitted, the IC card 43 can be taken out with almost no load.

The connector 20 described above is housed in the box body, as in FIG. At that time, the lever 41 is exposed to the outside of the box so that it can be operated from the outside of the box. According to this, by operating the lever 41 from the outside of the box, the IC card 43 can be connected to the connector.
It can be taken out from 20 with almost no load.

Needless to say, the present invention is not limited to an IC card and can be similarly applied to a connector for another type of circuit board.

[Effect of the Invention] As described above, according to the connector detachment mechanism of the present invention, the card is pressed by the back surface of the lever and the operation is performed with the thumb and forefinger when operating the lever.
Since the hand prevents the card from falling, there is no risk of the card popping out and falling, and the circuit board connected to the connector can be easily removed without any hindrance. Further, in terms of detaching work, the circuit board is sandwiched between the two levers following the detachment from the connector, so that the circuit board is prevented from popping out with the force of detachment from the connector.
