Detailed Description

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

The contents of the present invention will be further described in detail with reference to the specific embodiments, and fig. 1 and fig. 2 respectively show the explosion diagram and the assembly diagram of the TF card seat with the hook needle detachment prevention structure of the present invention, it can be known that the TF card seat mainly comprises several parts, such as a TF card 1, an insulation body 2, a metal terminal 3, an outer housing 4, a sliding member 5, and a locking mechanism 6, wherein a receiving groove 21 is provided on the upper plane of the insulation body 2 for the TF card 1 to be inserted (as shown in fig. 6). The outer cover 4 covers over the accommodating groove 21 and is detachably and fixedly connected with the insulating body 2. An avoiding hole 22 (shown in fig. 6) is formed in the bottom wall of the insulating body 2. The metal terminals 3 are fixedly connected to the insulating body 2, and the free ends thereof can be elastically abutted against the TF card 1 through the avoiding holes 22 (as shown in fig. 4). The sliding piece 5 is clamped between the insulating body 2 and the outer casing 4, and elastically abuts against the rear side wall of the TF card 1 under the action of the locking mechanism 6. A hooking protrusion 51 is provided at the right end of the slider 5, and a limit notch 11 (shown in fig. 3, 11, and 12) adapted to the hooking protrusion 51 is correspondingly provided on the rear side wall of the TF card 1. The latch mechanism 6 includes a spring member 61 and a latch needle 62. The spring member 61 abuts against the insulating body 2 and the sliding member 5 to drive the TF card 1 to move horizontally and slide in the accommodating groove 21 in the left-right direction (as shown in fig. 4). A shift chute 52 (shown in fig. 11) is provided on the upper plane of the slide 5. A limiting groove 23 (shown in fig. 6 and 7) is formed on the insulating body 2. The left end of the hook 62 is freely rotatably inserted into the above-mentioned limit groove 23, and the right end is freely slidably inserted into the shift chute 52, thereby completing the locking or unlocking of the TF card 1.

It should be emphasized here that the latch 62 includes a limiting section 621. The limiting section 621 is formed by laterally bending the left end of the latch needle 62 (as shown in fig. 5), and correspondingly, a limiting protrusion 231 (as shown in fig. 7 and 8) extends from the side wall of the limiting groove 23 directly above the limiting section 621. Through adopting above-mentioned technical scheme to set up to the left end portion that has prevented crochet hook 62 effectively from taking place "drunkenness" phenomenon along the direction of height in spacing groove 23, guarantee to place in shift chute 52 in its right-hand member portion all the time, and at TF card 1 in-process that slides, it carries out the adaptability along shift chute 52 and slides, and then has guaranteed TF card 1 locking and the smooth execution of unblock operation.

As a further improvement of the above technical solution, an elastic pressing arm 41 may be provided on the outer case 4 and always elastically presses against the latch needle 62 (as shown in fig. 1 and 9). Through adopting the above technical scheme to set up to further prevent effectively that crochet hook 62 from taking place "drunkenness" phenomenon along the direction of height, ensure that its spacing section 621 places in spacing groove 23 all the time.

The resilient pressing arm 41 is preferably directly punched out of the top wall of the outer shroud shell 4 in view of optimizing the manufacturing process and reducing the manufacturing cost.

Furthermore, the elastic pressing arm 41 is composed of two parts, namely an elastic bending section 411 and a flat pressing section 412, wherein the flat pressing section 412 is formed by directly extending back the elastic bending section 411. In addition, the elastic bending section 411 is arranged to be inclined by 15-25 ° with respect to the horizontal plane, and ensures that it has a certain floating amount corresponding to the outer casing 4, and has appropriate elasticity (as shown in fig. 9 and 10) to achieve the purpose of stably pressing the crochet hook 62 by the flat pressing section 412.

Also in view of reducing the manufacturing cost, the insulating body 2 is preferably a plastic injection-molded part. In the process of injection molding and manufacturing the insulating body 2, the limiting groove 23 for inserting the crochet hook 62 is directly formed, so that the groove milling process after the insulating body 2 is formed is omitted.

Furthermore, the insulating body 2 may be provided with a locking protrusion 24. The clamping protrusion 24 is formed by continuously extending the front and rear side walls of the insulating body 2, and correspondingly, clamping holes 42 (as shown in fig. 2, 6, 7, and 9) adapted to the clamping protrusion 24 are formed on the front and rear side walls of the outer housing 4. Therefore, the relative position relationship between the clamping protrusion 24 and the clamping hole 42 can be conveniently changed to easily and quickly realize the separation and combination of the outer cover shell 4 relative to the insulating body 2, and the time required by assembly is effectively shortened. Of course, as a further optimization of the above technical solution, the outer side wall of the clamping protrusion 24 may be chamfered inward to form a guiding inclined surface 241 (as shown in fig. 6), so as to ensure that the clamping protrusion 24 is smoothly installed into the clamping hole 42.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
