Structure 333 is resisted. Here, "the above-described pressing portion 3104 is disposed apart from the above-described plate accommodating portion 332 with respect to the contact portion 3103" means that the plate accommodating portion 332 and the terminal accommodating portion 331 are vertically disposed in the thickness direction of the urging mechanism 33, Further, the plate accommodating portion 332 is located above and the terminal accommodating portion 331 is located below. Therefore, the contact portion 3103 is formed close to the plate accommodating portion 332, and the pressing portion 3104 is provided away from the plate accommodating portion 332.

A latching arm 334 is disposed on the two sides of the latching mechanism 33. The latching arm 334 includes a connecting portion 3341 connected to the latching mechanism 33 and the connecting portion 3341 and is suspended from the terminal receiving portion 331. The latching arm 3342 is provided with a claw 3343 at the end of the latching arm 3342, and a latch 3344 between the latch 3343 and the connecting portion 3341 is further protruded from the latching arm 3342.

The two slides 308 are distributed at the left and right ends of the abutting portion 301, and are respectively recessed from the front end surface of the abutting portion 301. Defining the two ends of the slide rail 308 as a predetermined position and a fixed position, respectively, the push lock mechanism 33 and the slide rail 308 cooperate with each other, so that the push lock mechanism 33 is displaced between the predetermined position and the fixed position, when the foregoing When the push lock mechanism 33 is in the fixed position, the flexible circuit board 11 is electrically connected to the terminal 310.

In the present embodiment, the slide rail 308 is provided in a blind groove shape (that is, one end is open and the other end is closed). A stop block 309 is protruded from the inner wall of the slide rail 308, and the stop block 309 is disposed at a predetermined position of the slide rail 308, so that when the aforementioned claw 3343 is latched with the stop block 309, When the push lock mechanism 33 does not reach the fixed position, the push lock mechanism 33 is prevented from being completely separated from the insulative housing 30, and when the hook 3344 is latched with the stop block 309, the push lock mechanism 33 can be reached. After the position is fixed, the push lock mechanism 33 is restricted from being displaced in the receiving groove 308 to prevent the push lock mechanism 33 from being withdrawn.

Therefore, it can be concluded that the predetermined position of the push lock mechanism 33 is that the latching arm 334 protrudes into the slide 308, and the aforementioned claw 3343 and the stop block 309 are mutually fixed and fixed; the push lock mechanism The fixed position of the latching arm 334 is inserted into the slide rail 308, and the hook 3344 and the stop block 309 are mutually fastened; thereby, the predetermined position is relative to the slide rail 308. The free end of the pressing portion 3104 extends into the rear end of the terminal accommodating portion 331, and the pressing structure 333 is opposite to the pressing portion 3104, when the urging mechanism 33 is in the predetermined position. Correspondingly, in the uncompressed state, the contact portion 3103 is in a non-contact state corresponding to the flexible circuit board 11; when the push lock mechanism 33 is in the fixed position, the pressing structure 333 is pressed against the pressing portion. 3104. The contact portion 3103 protrudes into the board receiving portion 332 and is in abutting connection with the flexible circuit board 11.

It should be noted that although the slide rails 308 are disposed at the left and right ends of the mating portion 301, they are not opened to the left side wall 306 and the right side wall 307 of the mating portion 301. The slide rail 308 is simultaneously opened at the top wall 304 and the bottom wall 305 of the abutting portion 301, so that the lock mechanism 33 can be confirmed by observing the positional relationship between the claw 3343 (or the hook 3344) and the stopper block 309. Is it in a fixed position? The stop block 309 is disposed at a position close to the front end surface of the abutting portion 301 in the sliding path 308, and the stop block 309 and the aforementioned claw 3343 are planar stops, and the stop block 309 and the foregoing hook 3344 There is a bevel stop between them.

Specifically, in the embodiment, the push lock mechanism 33 is an integrally formed structural member, and the whole is substantially a rectangular block. The terminal receiving portion 331 and the plate receiving portion 332 both extend forward and backward through the push lock mechanism 33, and The push lock mechanism 33 is disposed up and down in the foregoing to facilitate the mounting of the abutting arm 3101 and the flexible circuit board 11 of the terminal 310 from the front to the rear or from the rear to the front.

Of course, when the flexible circuit board 11 and the push lock mechanism 33 are not fixed, the flexible circuit board 11 can freely enter and exit in the board housing portion 332 with respect to the push lock mechanism 33.

By the above arrangement of the push lock mechanism 33, the flexible circuit board 11 is conveniently inserted, that is, the push lock mechanism 33 is pre-positioned to a predetermined position, and the lock arm 334 is inserted into the slide rail 308, the foregoing The claw 3343 and the stopper 309 are fastened to each other, and the free end of the pressing portion 3104 extends into the rear end of the terminal accommodating portion 331, and the pressing structure 333 corresponds to the pressing portion 3104 and is not pressed. In this case, the flexible circuit board 11 can be extended from the front direction of the push lock mechanism 33 through the board receiving portion 332 to the position of the contact portion 3103 of the terminal 310, so that the golden finger on the flexible circuit board 11 (not shown) Corresponding to the contact portion 3103, it is in an unfloating state; after the flexible circuit board 11 is inserted, only the push lock mechanism 33 needs to be moved from the pre-position position toward the fixed position, that is, the pressing structure 333 and the pressing force are pressed. The cooperation of the portion 3104 realizes the abutting connection of the contact portion 3103 with the gold finger on the flexible circuit board 11, and the latching mechanism 33 is held at a fixed position by the mutual fastening of the hook 3344 and the stopper block 309 while passing through Buckle block 3361 The recessed portion 11 of the flexible circuit board 111 are engaged to prevent the flexible circuit board 11 is moved in the plate receiving portion 332.

Since the flexible circuit board 11 is fixed in the casing 100 in the present invention, the push-pull mechanism 33 can be moved in and out in a free state when the flexible circuit board 11 is inserted until the push lock mechanism 33 is moved to the fixed position. The fixing of the push lock mechanism 33 and the flexible circuit board 11 is realized; of course, when the flexible circuit board 11 is in an unfixed state, the flexible circuit board 11 and the push lock mechanism 33 may be first fixedly integrated, and then the push lock mechanism 33 is pushed. The flexible circuit board 11 is moved together with the push lock mechanism 33 until the push lock mechanism 33 is moved to the fixed position.
