The terminal 13 is formed of a leaf spring and has elastic force, and the base 14 is It is bent slightly upward and extends forward from the bottom surface of the rear part 12 of the connector. and, The front part of the connector main body 11 is curved upward and extends diagonally rearward, and further downward. The contact portion 15 is curved to form a contact portion 15 that protrudes upward, and the tip portion 16 is horizontally curved. It has been extended to

[0011] In addition, as shown in FIG. A covering cover 17 is pivotally mounted so as to be vertically movable. The cover 17 is made of metal. has been done. Then, install the torsion spring 18 inside the connector body 11. , while locking one side of the torsion spring 18 to the connector body 11, and locking the other side of the torsion spring 18 to the connector body 11. is brought into contact with the inner surface of the cover 17 to urge the cover 17 upward. Therefore, When the connector 10 is not in use, a cover 17 covers and protects the terminals 13.

0012 A first locking portion 19 extends from the upper end of the side surface of the connector body 11 to the lower middle portion. a is protruded from the lower end of the side surface of the connector body 11 to the upper middle part. A locking portion 19b is provided in a protruding manner. A groove is formed at the lower end of the first locking portion 19a. The torsion spring 18 is engaged with this groove, and the first locking portion 19a and One side of the torsion spring 18 is held by the second locking part 19b, and the connector body is It is fixed to the side of 11.

[0013] Furthermore, as shown in FIGS. 1 and 2, a window 20 is opened at the front and rear intermediate portions of the cover 17. A slit 21 is formed at the front and rear of the window 20. The slit 21 is shown in FIG. As shown in FIG. Fits window 20 A separator 22 made of synthetic resin is attached. The separator 22 The side and bottom parts between the window 20 and the slit 21 of the cover 17 are formed by insert molding. It is fixed to the edge of the window 20 surrounding the surface, and the separator 22 has a slit-shaped exposure. An exit hole 23 is drilled. The exposure hole 23 is formed facing the terminal 13, The contact portion 15 of the terminal 13 is loosely inserted into the exposure hole 23. Therefore, separator 2 2, the terminals 13, 13... are isolated from each other.

[0014] The separator 22 is insert-molded into the slit 21 that expands upward. Since the separator 22 is fixed at the tapered part, there is no possibility that the separator 22 will fall off downward. is prevented. Further, the separator 22 does not protrude from the upper surface of the cover 17. Therefore, the plug can be smoothly slid onto the top surface of the cover 17 as described later. .

[0015] Furthermore, as shown in FIG. 2, a pressing portion 22a protrudes from the rear inner surface of the separator 22. It is set up. As shown in FIG. 6, by providing this pressing portion 22a, the cover Even if the cover 17 is pressed strongly and the rotation angle of the cover 17 becomes large, the pressing part 22a The tip 16 of the terminal 13 is pressed to be linked to rotation. Therefore, the contact portion 1 of the terminal 13 5 is moved downward to prevent excessive protrusion from the cover 17. Furthermore, the connector The terminal 13 is bent and folded back at the front part of the main body 11, and Since the terminal 13 is bent downward on the side, the terminal 1 is bent by the pressing part 22a. 3 distributes the bending load at the base 14, front part, and contact part 15 to prevent a decrease in elastic force. It has stopped. Furthermore, since the terminal 13 is folded back at the front to extend the overall length, A decrease in elastic force is prevented.

Applicable The pressing portion 22b presses the front of the contact portion 15 of the terminal 13 when the cover 17 is rotated significantly. It is configured to press. In such a case, the position to be pressed by the pressing part 22b should not be touched. Since it is set between the contact portion 15 and the base 14, the cover of the contact portion 15 provided on the tip side By stabilizing the amount of protrusion from the bar 17, the protrusion height of many terminals 13, 13... that are arranged in parallel can be kept constant.

[0017] Therefore, when the connector 10 is not in use, the cover 17 may be pressed by some external force or the like. Even if the contact portion 15 of the terminal 13 protrudes, the amount of protrusion is kept constant and the amount of protrusion is regulated. Therefore, prevent the exposed portion of the terminal 13 from being caught and deformed or damaged as much as possible. To prevent.

(not shown). At this time, the connection part of the torsion spring 18 The vicinity of 25 is arranged upwardly and downwardly at the first locking part 19a and the second locking part 19b. Since movement in the left and right direction is restricted, vertical movement of the connection portion 25 is prevented. This makes it possible to easily insert the connecting portion 25 into the circuit board.

[0018] As shown in FIG. 8, the plug 26 is inserted into the cover 17 from the front of the connector 10. Slide the plug 26 onto the top surface of the cover 17 and press the slope of the slanted cover 17. When the cover 17 faces the upper surface of the exposure hole 23, it rotates downward and covers the upper surface of the exposure hole 23. The contact portion 15 of the terminal 13 is exposed. Therefore, connect the terminal 27 of the plug 26. The contact portion 15 of the terminal 13 of the terminal 10 is pressed into contact with the terminal 13 of the terminal 10 . For convenience of explanation, plug 2 is shown in Figure 8. 6 and the top surface of the cover 17, but in reality, the plug 26 is connected to the connector main body. It is in contact with the upper surface of the cover 17 of the body 11.

[0019] At this time, a gap is provided between the front edge of the separator 22 and the tip 16 of the terminal 13. Therefore, before the front edge comes into contact with the tip 16 of the terminal 13, , when the amount of descent of the cover 17 is small, the terminal 13 of the connector 10 is attached to the cover 17. will not be interfered with. Therefore, the contact portion 15 of the terminal 13 is exposed through the exposure hole 23. The terminal 27 of the plug 26 is brought into pressure contact with the terminal 27 of the plug 26.

[0020] Furthermore, by changing the height of the pressing portion 22a shown in FIG. It is possible to change the contact timing between the connecting part 15 of the plug 26 and the terminal 27 of the plug 26. Wear. Therefore, for example, contact the ground terminal, power supply terminal, and signal terminal in this order to connect ICs, etc. can prevent the destruction of On the other hand, since the cover 17 is made of metal, electrically charged objects such as a human body may 10, static electricity is discharged to the cover 17 without being discharged to the terminals 13, 13... Powered up. The static electricity is then removed to ground via the torsion spring 18. . Furthermore, since the separator 22 is made of resin, the terminals 13, 13... There will be no short circuit even if the terminals 13, 13... At the same time, the terminals 13, 13, . . . are protected.
