Description

Technical Field

[0001] The invention belongs to the technical field of connectors, and in particular relates to a USB connector socket and a USB connector. Background Art

[0002] The USB connector includes a USB connector socket and a USB connector plug. When in use, the USB connector socket and the USB connector plug are used for connection. There are many types of USB connectors on the market. Among them, in the existing public document, CN105449435A-USB socket, it is disclosed that a mounting seat, a socket body threaded with the mounting seat, a USB socket body arranged on the socket body, and a panel cover sleeved on the USB socket body are provided. The panel cover is detachably connected to the socket body, and has a double-sided socket, which can be used for double plugs.

[0003] However, traditional USB connector sockets are usually of an integral structure. Once an internal fault occurs, the entire socket needs to be disassembled for repair, which is complicated and time-consuming. In addition, existing USB connector sockets generally have only fixed socket orientations and numbers, which makes it difficult to meet the needs of different device layouts and usage scenarios.

[0004] In addition, when the USB socket in the prior art is idle, the socket is often exposed to the air, which can easily cause external dust or debris to fill the inside of the USB socket, thereby causing a certain impact on the use of the USB socket. In the mildest case, the socket and the plug are in poor contact, resulting in the inability to use it normally. In the worst case, the internal components of the socket are deformed, resulting in damage to the socket.

[0005] Furthermore, conventional USB connector sockets are usually designed to accommodate plugs of a single size or a specific size range, and may not be able to meet the need when two USB connector plugs of different sizes need to be inserted at the same time. To this end, we provide a USB connector socket and a USB connector to solve the above problems. Summary of the invention

The connecting seat 300 is movably connected to the peripheral side of the socket shell 100. The socket shell 100 comprises a first shell 110 and a second shell 120. The first shell 110 and the second shell 120 are snap-fitted and spliced. The outer sides of the first shell 110 and the second shell 120 are both provided with a socket 200. The interiors of the first shell 110 and the second shell 120 are both connected to the base 400, and a USB connector interface 500 is fixed to the top of each base 400.

[0045] Specifically, the inner side surfaces of the first shell 110 and the second shell 120 are both provided with openings, and the shell seats 103 are fixed to the inner side openings of the first shell 110 and the second shell 120 by screws, and the peripheral sides of the first shell 110 and the peripheral sides of the second shell 120 are both fixed with arc rails 104, and both sides of the arc rails 104 are provided with inner grooves 1041, and the inner part of the inner groove 1041 is connected with a telescopic buckle, and the telescopic buckle includes a compression spring 1042 and a buckle 1043, and the inner end of the buckle 1043 is fixed with the compression spring 1042, and the inner end of the buckle 1043 is movably installed in the inner groove 1041;

[0046] Grooves 1001 are provided on both sides of the arc-shaped rail 104 in the first housing 110 , and bumps 1002 are fixed on both sides of the arc-shaped rail 104 in the second housing 120 . The size of the grooves 1001 matches the size of the bumps 1002 .

[0047] Furthermore, the connecting seat 300 includes a first seat plate 310 and a second seat plate 320. The first seat plate 310 is slidably connected to the arc-shaped rail 104 of the first shell 110, and the second seat plate 320 is slidably connected to the arc-shaped rail 104 of the second shell 120. The two arc-shaped rails 104 are assembled to form a ring structure.

[0048] The first seat plate 310 and the second seat plate 320 are each provided with two symmetrically arranged clamping holes 311 , and the arc-shaped corners of the first seat plate 310 and the arc-shaped corners of the second seat plate 320 are both provided with mounting holes 312 , and the size of the clamping holes 311 matches the size of the telescopic buckle in the arc rail 104 .

[0049] The operation process of this embodiment is as follows: before the assembly is used, the first shell 110 and the second shell 120 can be assembled into one piece by inserting the protrusion 1002 of the second shell 120 into the groove 1001 of the first shell 110. After the assembly, the first seat plate 310 and the second seat plate 320 are fixed at the preset installation position by screws, and then the assembly can be used;

[0050] In addition, when the socket shell 100 is assembled for use, the first shell 110 and the second shell 120 used horizontally can be turned to a vertical state for use by pressing the telescopic buckle and then rotating the socket shell 100. When turned to the vertical state, each telescopic buckle will be transmitted from the corresponding card hole 311 again, so that the position can be limited in time after the orientation is adjusted;

[0051] It should be supplemented that: when the No. 1 shell 110 or the No. 2 shell 120 is used alone, the No. 1 seat plate 310 is fixed at a preset installation position with screws, and the No. 1 shell 110 can be installed and used alone, while the No. 2 seat plate 320 is fixed at a preset installation position with screws, and the No. 2 shell 120 can be installed and used alone.

[0052] Example 2

[0053] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 On the basis of Example 1, the socket 200 includes a slot 210 and a slot 220. The slot 210 passes through the movable slot 101. The slot 220 is opened at the outer end opening of the slot 210. Wire holes 230 are opened at the four corners of the slot 220. A rubber rope 250 is fixed inside each wire hole 230. Two symmetrically arranged shaft rods are fixed inside the slot 220. A door panel 240 is movably connected to each shaft rod in the slot 220. The rubber ropes 250 on both sides of the slot 220 are respectively connected to the door panels 240 on both sides.

[0054] Specifically, the side surface of the first housing 110 and the side surface of the second housing 120 are both provided with movable grooves 101 , and shielding plates 520 are inserted inside the movable grooves 101 .

[0055] Furthermore, a baffle strip 510 is fixed to the outer peripheral side of the connection port of the USB connector interface 500 , and the connection port of the USB connector interface 500 is inserted into the central groove of the shield 520 , and the baffle strip 510 abuts against the shield 520 .

[0056] The operation process of this embodiment is as follows: when the USB connector plug 700 is not inserted, the door panel 240 is in a closed state under the pulling force of the rubber rope 250, which can prevent dust, debris, etc. from entering the slot 210, thereby protecting the USB connector interface 500;

[0057] During use, when the USB connector plug 700 is inserted, the USB connector plug 700 first contacts the door panel 240. As the USB connector plug 700 is inserted, the door panel 240 will overcome the tension of the rubber rope 250 under the squeezing of the plug and rotate around the axis to open, providing guidance and space for the USB connector plug 700 to enter the slot 210, so that the USB connector plug 700 can be smoothly inserted into the USB connector interface 500.

[0058] Example 3

[0059] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 On the basis of Example 1 and Example 2, the base 400 of the No. 1 shell 110 and the base 400 of the No. 2 shell 120 are connected by a group of telescopic mechanisms 600 arranged in a rectangular distribution. The telescopic mechanism 600 includes a telescopic rod 610 and a spring 620. The circular plates at both ends of the telescopic rod 610 are respectively fixed on the side plates of the slide 420 on both sides. The telescopic rod 610 includes a column and a column tube. A hollow cylinder groove is opened inside the connecting end of the column tube. The rod body of the column is inserted in the cylinder groove of the column tube. The outer ends of the column and the outer ends of the column tube are fixed with circular plates. The outer sleeve of the telescopic rod 610 is provided with a spring 620, and the two ends of the spring 620 are respectively connected to the circular plates at both ends of the telescopic rod 610.

[0060] Specifically, the base 400 includes a slide rail 410, a slide seat 420 and a mainboard 430. The two mirror-set slide rails 410 are fixed to the shell base 103. The slide seat 420 is slidably connected between the two slide rails 410. The mainboard 430 is fixed on the slide seat 420. The USB connector interface 500 is fixed on the mainboard 430.

[0061] Furthermore, a group of rectangularly distributed through holes 102 are provided on the side of the first housing 110 and the side of the second housing 120 located directly below the movable slot 101;

[0062] The through holes 102 of the first shell 110 and the through holes 102 of the second shell 120 are respectively arranged horizontally correspondingly, and the telescopic mechanism 600 crosses the horizontally corresponding through holes 102 of the first shell 110 and the second shell 120 .

[0063] The operation process of this embodiment is as follows: when two USB connector plugs 700 of different sizes are inserted into the socket shell 100 at the same time, that is, when two USB connector plugs 700 of different sizes are inserted into the socket 200 of the No. 1 shell 110 and the socket 200 of the No. 2 shell 120 at the same time, if the normal use spacing of the two USB connector plugs 700 is greater than the spacing between the two sockets 200 in the socket shell 100, one of the USB connector plugs 700 is inserted first, and then when the other USB connector plug 700 is inserted, the two USB connector plugs 700 will be squeezed by external force, and at this time, the telescopic rods 610 in each telescopic mechanism 600 will be stretched at the same time, and the springs 620 in each telescopic mechanism 600 will also be stretched synchronously, so that the slide 420 drives the respective USB connector interface 500 to move horizontally on the slide rail 410, thereby increasing the spacing between the two slides 420, thereby increasing the spacing between the two USB connector interfaces 500, and adjusting the use spacing between the two USB connector plugs 700 through the telescopic mechanism 600;

[0064] When not in use, when one of the USB connector plugs 700 is pulled out, due to the elastic effect of the spring 620, the telescopic rods 610 in each telescopic mechanism 600 will be simultaneously retracted back to the original state, so that the distance between the two sockets 200 returns to the initial state;

[0065] It should be noted that when the USB connector interface 500 moves along with the slide 420, the shield 520 will also be driven to move synchronously in the movable slot 101. Through the shielding of the shield 520, only the connection port of the USB connector interface 500 is exposed in the slot 210 for use, while the rest of the slot 210 is always shielded to achieve the purpose of dust prevention.
