Description

Technical Field

[0001] This utility model relates to the field of shielding shell technology, and in particular to an inverted structure of a rubber core and a shielding shell. Background Technology

[0002] In the field of electronic connectors, especially for interfaces requiring electromagnetic shielding, the structure typically consists of two main parts: a core, an internal frame made of insulating plastic used to secure the conductive terminals; and a shielding shell, an outer shell made of metal that surrounds the core, providing electromagnetic shielding and mechanical protection. To achieve shielding functionality and ensure structural integrity, the core and shielding shell must be securely and stably assembled together. The snap-fit ​​design has become the most mainstream connection method due to its low cost, simple assembly, and lack of the need for additional fasteners.

[0003] In common inverted snap-fit ​​structures, individual inverted snap-fit ​​fixing of the core may lead to local stress concentration and insufficient overall holding force. Under vibration, impact, or frequent insertion and removal, the core is prone to shaking. Traditional inverted snap-fit ​​structures usually only provide locking force in the insertion direction, which is insufficient for restraining the shaking of the vertical plane in the insertion direction. This results in micro-movements when the connector is mated, affecting signal stability. Utility Model Content

[0004] The purpose of this invention is to provide an inverted structure for the core and the shielding shell, which solves the problem that the core and the shielding shell may wobble after being fixed by the inverted structure, thus affecting the stability of the connection signal.

[0005] To achieve the above objectives, an inverted structure for a rubber core and a shielding shell is provided, comprising: a shielding shell, a rubber core, and a disassembly handle. The inner front wall of the shielding shell is sequentially provided with a large inclined surface, a small inclined surface, and a straight surface. The surfaces of the large and small inclined surfaces are slidably connected to the outer wall of the rubber core. The inner wall of the straight surface is slidably connected to the outer wall of the rubber core. The left and right inner walls of the large, small, and straight surfaces are provided with sliding grooves. The left and right outer walls of the rubber core are fixedly connected with locking blocks. The upper and lower walls of the locking blocks are slidably connected to the upper and lower inner walls of the first sliding groove. The upper and lower inner walls of the large, small, and straight surfaces are provided with second sliding grooves. The upper and lower outer walls of the rubber core are fixedly connected with sliders. The outer wall of the slider is slidably connected to the inner wall of the second slide groove. The upper and lower inner walls of the shielding shell are fixedly connected to slide groove blocks, which form slide groove three. The left and right inner walls of slide groove three are slidably connected to the left and right outer walls of the slider. The lower end of the slide groove block fixedly connected to the upper inner wall of the shielding shell is slidably connected to the upper surface of the rubber core. The upper end of the slide groove block fixedly connected to the lower inner wall of the shielding shell is slidably connected to the lower surface of the rubber core. The left and right inner walls of the shielding shell are fixedly connected to fixing blocks. The inward side of the fixing blocks is slidably connected to the left and right outer walls of the rubber core. The left and right inner walls of the shielding shell are fixedly connected to buckles. The inward inclined surface of the buckles is slidably connected to the outward inclined surface of the buckles.

[0006] The disassembly handle is fixedly connected to the left and right ends with disassembly blocks. The outward inclined surface of the disassembly block is slidably connected to the inward inclined surface of the buckle. The left and right inner walls of the disassembly handle are slidably connected to the left and right outer walls of the rubber core. The upper and lower outer walls of the left and right parts of the disassembly handle are slidably connected to the upper and lower inner walls of the slide groove.

[0007] According to the aforementioned inverted structure of the rubber core and the shielding shell, a mating block is fixedly connected to the inner wall of the rubber core.

[0008] According to the aforementioned inverted structure of the rubber core and the shielding shell, a handle is fixedly connected to the front surface of the rubber core located above the mating block.

[0009] According to the aforementioned inverted structure of the core and shielding shell, a connection point is fixedly connected to the rear surface of the shielding shell.

[0010] According to the aforementioned inverted structure of the core and shielding shell, connecting blocks are fixedly connected to the upper surface and left and right outer walls of the connection.

[0011] According to the aforementioned inverted structure of the rubber core and shielding shell, the number of sliding blocks is five, the number of sliders is three, two sliding blocks fixedly connected to the upper inner wall of the shielding shell form a sliding groove three, which slides in cooperation with a slider fixedly connected to the upper surface of the rubber core, and three sliding blocks fixedly connected to the lower inner wall of the shielding shell form two sliding groove three, which slide in cooperation with two sliders fixedly connected to the lower surface of the rubber core.

[0012] According to the aforementioned inverted structure of the core and shielding shell, the number of fixing blocks is four and they are symmetrically arranged on the left and right inner walls of the shielding shell.

[0013] According to the aforementioned inverted structure of the rubber core and shielding shell, both the handle and the disassembly handle are chamfered for easy gripping.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. The three-section design of large slope, small slope and straight surface makes it easier to insert the rubber core into the shielding shell. The sliding cooperation between the slider on the rubber core and the sliding groove three allows the cooperation between the locking block and the buckle to lock and fix the rubber core. The fixing block keeps the rubber core stable in the horizontal direction, which greatly enhances the overall connection stability and vibration resistance.

[0016] 2. The disassembly block on the handle slides with the buckle, and the disassembly block fits into the buckle. The rubber core can be quickly removed by pulling the handle. The structure is simple, fast and efficient.

[0028] Reference Figure 1-6This utility model discloses an inverted structure for a rubber core and a shielding shell, comprising: a shielding shell 1, a rubber core 2, and a disassembly handle 3. The inner front wall of the shielding shell 1 is sequentially provided with a large inclined surface 101, a small inclined surface 102, and a straight surface 103. The large inclined surface 101 is the first segment with a large angle, used to quickly guide the rubber core 2 into the shielding shell 1. The small inclined surface 102 has a small angle, facilitating the insertion of the rubber core 2 into the shielding shell 1. The straight surface 103 fits snugly against the outer wall of the rubber core 2, allowing the rubber core 2 to smoothly connect to the fixing block 107 and sliding block 107 inside the shielding shell 1. The surfaces of the groove block 108, the large inclined surface 101, and the small inclined surface 102 are all slidably connected to the outer wall of the rubber core 2. The inner wall of the straight surface 103 is slidably connected to the outer wall of the rubber core 2 to ensure the stable entry of the rubber core 2. The left and right inner walls of the large inclined surface 101, the small inclined surface 102, and the straight surface 103 are provided with sliding grooves 104. The left and right outer walls of the rubber core 2 are fixedly connected with locking blocks 201. The upper and lower walls of the locking blocks 201 are slidably connected to the upper and lower inner walls of the sliding grooves 104 to keep the rubber core 2 from shaking. The large inclined surface 101, the small inclined surface 102, and the straight surface 103 are all slidably connected to the outer wall of the rubber core 2. The upper and lower inner walls are provided with sliding grooves 105. Slider 202 is fixedly connected to the upper and lower outer walls of the rubber core 2. The outer wall of slider 202 slides against the inner wall of sliding groove 105, allowing the rubber core 2 to enter the shielding shell 1 stably without shaking. Sliding blocks 108 are fixedly connected to the upper and lower inner walls of the shielding shell 1, forming sliding groove 109. The left and right inner walls of sliding groove 109 slide against the left and right outer walls of slider 202. The lower end of the sliding block 108 fixedly connected to the upper inner wall of the shielding shell 1 slides against the upper surface of the rubber core 2. The upper end of the sliding block 108, which is fixedly connected to the inner wall, is slidably connected to the lower surface of the core 2 to ensure that the core 2 enters stably. It cooperates with the buckle 106. The left and right inner walls of the shielding shell 1 are fixedly connected with the fixing blocks 107. The inner side of the fixing blocks 107 is slidably connected to the left and right outer walls of the core 2 to ensure that the core 2 is stable and does not shake. The left and right inner walls of the shielding shell 1 are fixedly connected with the buckles 106. The inner inclined surface of the buckles 106 is slidably connected to the outer inclined surface of the buckle 201. The buckles 106 and the buckles 201 are slidably engaged to lock and fix the core 2.

[0029] The left and right ends of the disassembly handle 3 are fixedly connected to disassembly blocks 301. The outward inclined surface of the disassembly block 301 is slidably connected to the inward inclined surface of the buckle 106, so that the buckle 106 no longer locks the buckle block 201, and the rubber core 2 can be slidably removed. The left and right inner walls of the disassembly handle 3 are slidably connected to the left and right outer walls of the rubber core 2, ensuring the stability of the disassembly handle 3 in the left and right direction. The upper and lower outer walls of the left and right parts of the disassembly handle 3 are slidably connected to the upper and lower inner walls of the slide groove 104, ensuring the stability of the disassembly handle 3 in the up and down direction.

[0030] A mating block 204 is fixedly connected to the inner wall of the core 2, featuring a foolproof insertion design for easy mating with electronic connectors such as terminals. A handle 203 is fixedly connected to the front surface of the core 2 above the mating block 204, facilitating the removal of the core 2. A connection point 110 is fixedly connected to the rear surface of the shielding shell 1 for connecting to an electronic connector. Connecting blocks 111 are fixedly connected to the upper surface and left and right outer walls of the connection point 110 for guiding the connection. There are five sliding blocks 108 and three sliding blocks 202. The inner wall of the shielding shell 1 is fixedly connected to... Two sliding blocks 108 form a sliding groove 3 109, which slides in cooperation with a slider 202 fixedly connected to the upper surface of the core 2. Three sliding blocks 108 fixedly connected to the lower inner wall of the shielding shell 1 form two sliding grooves 3 109, which slide in cooperation with two sliders 202 fixedly connected to the lower surface of the core 2, ensuring that the core 2 and the shielding shell 1 are in the correct vertical direction when they are in cooperation. There are four fixing blocks 107, which are symmetrically arranged on the left and right inner walls of the shielding shell 1 to ensure the stability of the core 2. Both the handle 203 and the disassembly handle 3 are chamfered for easy gripping.

[0031] Working principle: When the adhesive core 2 enters the shielding shell 1, the shielding shell 1 has a three-section design: a large inclined surface 101, a small inclined surface 102, and a straight surface 103. The large inclined surface 101 is the first section, with a large angle, used to quickly guide the adhesive core 2 into the shielding shell 1. The small inclined surface 102 has a small angle, which facilitates the insertion of the adhesive core 2 into the shielding shell 1. The straight surface 103 fits against the outer wall of the adhesive core 2, allowing the adhesive core 2 to smoothly connect to the fixing block 107 and the sliding block 108 inside the shielding shell 1. To ensure the stable entry of the glue core 2, the upper and lower walls of the locking block 201 slide against the upper and lower inner walls of the first slide groove 104, preventing the glue core 2 from wobbling. The outer wall of the slider 202 slides against the inner wall of the second slide groove 105, allowing the glue core 2 to enter the shielding shell 1 stably without wobbling. The third slide groove 109, composed of slide groove blocks 108, slides against the slider 202. The slide groove blocks 108 slide against the upper and lower surfaces of the glue core 2, ensuring that the glue core 2 does not wobble in the vertical direction. The fixing block 107 and the glue core 2 are also connected. The outer walls of core 2 slide to ensure that core 2 does not wobble in the left and right directions. The buckle 106 and the locking block 201 slide to lock and fix core 2, ensuring that core 2 is stably fixed in the shielding shell 1. When core 2 needs to be disassembled, insert the left and right parts of disassembly handle 3 along the slide groove 104. The upper and lower outer walls of the left and right parts of disassembly handle 3 slide to connect with the upper and lower inner walls of slide groove 104, ensuring the stability of disassembly handle 3 in the up and down direction when it moves. The left and right inner walls of disassembly handle 3 slide to connect with the left and right outer walls of core 2, ensuring the stability of disassembly handle 3 in the left and right direction when it moves. After disassembly handle 3 is inserted, until the end of disassembly block 301 is attached to locking block 201 and can no longer move, the outward inclined surface of disassembly block 301 slides to engage with the inward inclined surface of buckle 106, causing buckle 106 to deform to the left and right, so that buckle 106 no longer locks locking block 201. Then pull handle 203 to pull core 2 out of shielding shell 1.

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.
