Technical Field
[0001] This utility model relates to the field of USB connector technology, and in particular to a male USB connector. Background Technology
[0002] Chinese patent document CN212462115U discloses a USB-A male connector structure, including a metal shell, a plastic body, and multiple terminals. The metal shell surrounds the plastic body, which has multiple parallel grooves. The number of terminals is the same as the number of grooves. A plastic gland is provided between adjacent grooves. A limiting platform is provided on the top of the plastic gland, with the width of the limiting platform being greater than the width of the plastic gland. The plastic body also includes a pressure block that extends across the multiple grooves. The multiple terminals pass through the pressure block and are respectively accommodated in the grooves. The pressure block divides the terminals into a contact area and a soldering area. The soldering area is close to the plastic gland, and the end of the limiting platform extending beyond the plastic gland contacts the soldering area. By adding the limiting platform to increase the height of the plastic gland, the phenomenon of solder overflow and short circuit can be effectively avoided. At the same time, the soldering area of the terminal is pressed and fixed by the portion of the limiting platform extending beyond the plastic gland, effectively solving the short circuit caused by terminal lifting. The structure is simple and not prone to short circuit defects.
[0003] The plug portion of the aforementioned USB-A male connector is always exposed, making it easy for dust and other impurities to enter the plug's interior. This makes cleaning difficult and may lead to poor contact during connection, reducing the device's usability and practicality. Utility Model Content

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the description of the textual part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0021] Please see Figure 1-4 This utility model provides a technical solution: a USB connector male head, including a plastic shell 1 and a protective mechanism 3. A USB plug 2 is fixedly installed on one side of the plastic shell 1. The protective mechanism 3 is disposed outside the plastic shell 1 and includes a hollow block 301, a movable block 302 and a return spring 303. A set of symmetrically arranged hollow blocks 301 are fixedly installed on the front and rear sides of the plastic shell 1. The outer wall of the hollow block 301 has a strip-shaped opening. The inner walls of the two sets of hollow blocks 301 are slidably connected to the outer wall of a set of movable blocks 302. One side of the movable block 302 is fixedly connected to one end of the return spring 303, and the other end of the return spring 303 is fixedly connected to the inner wall of one side of the hollow block 301. An indicator light 7 is provided on the top of the plastic shell 1.
[0022] Secondly, the protective mechanism 3 also includes a rotating shaft 304, a strip plate 305, and a dust cover 306. A set of rotating shafts 304 are rotatably mounted on the front side of one set of movable blocks 302 and the rear side of another set of movable blocks 302. One end of each rotating shaft 304 extends through a strip opening to the outside of the hollow block 301. A set of strip plates 305 are fixedly mounted on the outer walls of both sets of rotating shafts 304. Adjacent sides of the strip plates 305 are fixedly connected to the front and rear sides of the dust cover 306, respectively. The USB plug 2 is located within the dust cover 306. Inside, a flexible sleeve 5 is fixedly installed on the inner wall of the dust cover 306. The flexible sleeve 5 fits against but is not connected to the outer wall of the USB plug 2. Multiple anti-slip textures 4 are provided on the top and bottom of the dust cover 306. The dust cover 306 is placed on the USB plug 2 to prevent dust and other impurities from entering the interior of the USB plug 2 and to minimize poor contact during connection. At the same time, the dust cover 306 is connected to the plastic shell 1 to prevent the dust cover 306 from being lost, thereby improving the usability and practicality of the device.
[0023] Furthermore, a label 6 is fixedly installed on the top of the plastic shell 1. The top of the label 6 is provided with an O-shaped protrusion to provide the user with a certain tactile feedback, indicating that the side with the label 6 is the front. The user can quickly distinguish the front and back without looking, making it convenient for the user to operate.
[0024] Working principle: When using this device, pinch the anti-slip texture 4 and pull the dust cover 306 outward to remove it from the USB plug 2. The dust cover 306 is flipped over by the rotation of the strip plate 305 on the rotating shaft 304 to avoid obstruction during connection. Holding the plastic shell 1 in your hand, you can feel the O-shaped protrusion on the label 6. With the side with the label 6 facing up, you can plug the USB plug 2 into the connector. When the USB plug 2 is unplugged from the connector... Then, pull the dust cover 306 outward, causing the movable block 302 to slide inside the hollow block 301, compressing the reset spring 303. Then rotate the strip plate 305 to adjust the dust cover 306 to one side of the USB plug 2. Release the dust cover 306, and under the elastic action of the reset spring 303, drive the movable block 302 to slide and reset inside the hollow block 301, thereby causing the dust cover 306 to be placed on the USB plug 2, thus protecting the USB plug 2.
[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
