BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector in which a cover is mounted on a connector body so as to be vertically movable, and a terminal is exposed by pressing the cover.

[0002]

2. Description of the Related Art A conventional connector of this type will be described with reference to FIGS. In the figure, reference numeral 1 denotes a connector, and the connector 1 is composed of a connector body 2, a plurality of terminals 3 each having a base portion attached to a rear groove of the connector body 2, a cover 4 attached to the connector body 2, and the like. . The terminal 3 is formed of a leaf spring, has an elastic force, is bent, and has a contact portion 5 protruding upward in an intermediate portion. The cover 4 is made of metal and is attached to the connector body 2 so as to be vertically movable. The cover 4 covers the upper surface of the connector body 2 and is biased upward by a spring 6. Therefore, when the connector 1 is not used, the cover 4 prevents the terminal 3 from being deformed or damaged by an external impact.

The spring 6 has one side portion fixed to the inner side surface of the cover 4 and the other side portion fixed to the upper surface of a projection 2a formed on one side surface of the connector body 2. The spring 6 extends downward from the protrusion 2a. A lower end portion 6a of the spring 6 is connected to a ground pattern of a circuit board (not shown) so as to eliminate static electricity.

Further, a window 7 is opened at the position of the contact portion 5 of the cover 4. Further, a separator 8 is attached to the window 7 by insert molding of a resin, and a plurality of terminals 3 arranged side by side are separated by the separator 8 to prevent a short circuit. Further, the periphery of the window 7 of the cover 4 is stepped downward to prevent the separator 8 from protruding from the upper surface of the cover 4, and a plug connector (not shown) can be smoothly slid on the upper surface of the connector 1. It is configured as follows.

Then, when the plug connector is slid sideways onto the upper surface of the cover 4 and pressed, the cover 4 descends and the contact portion 5 of the terminal 3 is exposed through the exposure hole of the separator 8. , Contact the terminals of the plug connector. Further, when the cover 4 is strongly pressed by an external impact and is largely rotated, the pressing portion 9 protruding on the inner surface of the front portion of the separator 8 pushes the tip portion of the terminal 3 downward to rotate the cover 4. It is linked to the movement. Therefore, the protrusion amount of the terminal 3 is regulated to be constant, and the terminal is prevented from being deformed by an external impact.

[0006]

The conventional connector described above has an elastic force so that it can be pressed against a terminal such as a plug. However, when the terminal is repeatedly pressed and bent by the pressing portion of the cover, so-called "sagging" occurs, the elastic force is reduced, and contact failure occurs.

Therefore, there arises a technical problem to be solved in order to prevent the elastic force of the terminal from decreasing so that the terminal can be surely connected to the terminal or the like of another connector. It aims to solve problems.

In addition, even if pressed by the pressing portion of the cover 17, which will be described later,
The stress of the terminal 13 is dispersed to reduce the elastic force of the terminal 13.
Is configured to prevent

Further, as shown in FIG. 3, a cover 17 for covering the upper part of the connector body 11 is provided at the rear portion of the connector body 11.
Is vertically pivoted. The cover 17 is made of metal. Then, the torsion spring 18 is attached to the inside of the connector main body 11, one side of the torsion spring 18 is locked to the connector main body 11, and the other side is brought into contact with the inner side surface of the cover 17 to cover the cover. 17 is biased upward. Therefore, when the connector 10 is not used, the cover 17 covers and protects the terminal 13.

A first engaging portion 19a is provided so as to project from an upper end portion of a side surface of the connector body 11 to a lower intermediate portion thereof, and a second engaging portion extends from a lower end portion of a side surface of the connector body 11 to an upper intermediate portion thereof. 19b is projected. A groove is formed at the lower end of the first locking portion 19a, and the torsion spring 18 is engaged with the groove, and the first locking portion 19a and the second locking portion 19b are twisted together. One side of the torsion spring 18 is sandwiched and fixed to the side surface of the connector body 11.

Further, as shown in FIGS. 1 and 2, a window 20 is opened in the front and rear intermediate portion of the cover 17, and slits 21 are opened in the front and rear of the window 20. As shown in FIGS. 2 and 5, the slit 21 is formed in a tapered shape by expanding the upper part. A separator 22 made of synthetic resin is attached to the window 20. The separator 22
Are fixed to the edge of the window 20 by surrounding the side surface and the lower surface between the window 20 and the slit 21 of the cover 17 by insert molding, and the slit-shaped exposure hole 2 in the separator 22.
3 is perforated. The exposing hole 23 is formed so as to face the terminal 13, and the contact portion 15 of the terminal 13 is formed in the exposing hole 23.
It is inserted in the inside. Therefore, the terminals 22 are isolated from each other by the separator 22.

Since the separator 22 is insert-molded in the slit 21 which is widened upward, and is fixed by the taper portion, the separator 22 is prevented from dropping downward. The separator 22 is a cover 1
Since it does not project from the upper surface of the plug 7, the plug can smoothly slide on the upper surface of the cover 17, as described later.

Further, as shown in FIG.
2 A pressing portion 22a is provided on the inner surface of the rear portion in a protruding manner. Figure 6
As shown in, by providing the pressing portion 22a,
Even if the cover 17 is strongly pressed and the rotation angle of the cover 17 becomes large, the pressing portion 22a presses the tip end portion 16 of the terminal 13 to interlock with the rotation. Therefore, the contact portion 15 of the terminal 13
Moves downward and is prevented from excessively protruding from the cover 17. Further, since the terminal 13 is curved and folded back at the front part of the connector body 11 and the terminal 13 is bent downward at the upper part of the connector body 11, the pressing of the pressing portion 22a causes the terminal 13 to be curved. The applied load is dispersed in the base portion 14, the front portion, and the contact portion 15 to prevent the elastic force from decreasing. Furthermore, since the terminal 13 is folded back at the front part and extends the entire length, a decrease in elastic force is prevented.

In addition, in FIG. 7, the pressing portion 22b is provided in the separator 2
2 is projected on the inner surface of the front part. The pressing portion 22b is configured to press the front of the contact portion 15 of the terminal 13 when the cover 17 is largely rotated. In that case, since the position where the pressing portion 22b presses is set between the contact portion 15 and the base portion 14, the amount of protrusion of the contact portion 15 provided on the tip end side from the cover 17 is stabilized, and a large number are provided. Terminal 1 installed in parallel
The protruding heights of 3, 13, ... Can be made constant.

Therefore, even if the cover 17 is pressed by some external impact or the like when the connector 10 is not used, the terminal 13
Since the protruding amount of the contact portion 15 is kept constant and the protruding amount is regulated, it is possible to prevent the exposed portion of the terminal 13 from being caught and deformed or damaged. Also, connector 1
0 is mounted on the circuit board 24, and the terminals 13, 13 ... Are connected to the electrodes on the board. On the other hand, as shown in FIG. 3, the torsion spring 18 has a connecting portion 25 formed by extending one side portion downward from the rear engaging portion 19a. Then, the connecting portion 25 is inserted into the insertion hole of the circuit board 24 and connected to the ground pattern (not shown) of the circuit board 24. At this time, the connecting portion 2 of the torsion spring 18
The vicinity of 5 is the first locking portion 19a and the second locking portion 19b.
Since the movement of the connecting portion 25 in the upward and downward directions and the horizontal direction is restricted, the vertical movement of the connecting portion 25 is prevented, and the work of inserting the connecting portion 25 into the circuit board can be facilitated.

Thus, as shown in FIG.
Slide the plug 26 onto the upper surface of the cover 17 from the front, and press the inclined surface of the inclined cover 17 while pressing the plug 2
When 6 is opposed to the upper surface of the exposure hole 23, the cover 17 rotates downward and the contact portion 15 of the terminal 13 is exposed through the exposure hole 23. Therefore, the contact portion 15 of the terminal 13 of the connector 10 is pressed against the terminal 27 of the plug 26. For convenience of explanation, although there is a gap between the plug 26 and the upper surface of the cover 17 in FIG. 8, the plug 26 is actually in contact with the upper surface of the cover 17 of the connector body 11.

At this time, since the front edge portion of the separator 22 and the tip portion 16 of the terminal 13 are spaced from each other, before the front edge portion contacts the tip portion 16 of the terminal 13,
That is, when the amount of lowering of the cover 17 is small, the cover 1
7 does not interfere with the terminal 13 of the connector 10.
Therefore, the contact portion 15 of the terminal 13 is exposed through the exposure hole 23 and is pressed against the terminal 27 of the plug 26.

By changing the height of the pressing portion 22a shown in FIG. 2, the contact timing between the connecting portion 15 of the connector 10 and the terminal 27 of the plug 26 can be changed. Therefore, for example, the ground terminal, the power supply terminal, and the signal terminal can be contacted in this order to prevent the destruction of the IC or the like. On the other hand, since the cover 17 is made of metal, even when a charged body such as a human body approaches the connector 10, static electricity is discharged to the cover 17 without being discharged to the terminals 13, 13 .... Then, the static electricity is discharged to the ground through the torsion spring 18. Further, since the separator 22 is made of resin, it does not cause a short circuit even if it comes into contact with the terminals 13, 13 ..., The terminals 13, 13 ... Are reliably separated, and the terminals 13, 13 ... Protect ...
