Description

Technical Field

[0001] This utility model relates to the field of digital tube technology, and in particular to an LED digital tube with a pin protection structure. Background Technology

[0002] An LED digital tube is an electronic display device composed of multiple light-emitting diodes (LEDs) arranged in a specific array. It displays numbers, letters, or simple symbols by controlling the on / off combinations of different LED segments. A typical structure includes a transparent or semi-transparent plastic housing, an internal LED chip assembly, and metal pins extending from the bottom of the housing. These pins serve as electrical connection interfaces, responsible for transmitting external drive signals to the LED chips, and are the core components for achieving physical bonding and electrical connection between the digital tube and the printed circuit board (PCB).

[0003] However, the pins of LED digital tubes are easily damaged during transportation, storage and installation. The main reason is that during transportation or handling, external forces such as stacking, squeezing, dropping and collision can easily cause the pins to bend, break or the solder pads to fall off. Utility Model Content

[0004] The main purpose of this invention is to provide an LED digital tube with a pin protection structure, which aims to solve the problem of easy damage to the pins of LED digital tubes during transportation and installation.

[0005] To achieve the above objectives, the present invention proposes an LED digital tube with a pin protection structure, comprising a housing and pins located at the bottom of the housing. The circumferential side of the housing is provided with a protection component, which includes multiple protection units. Each protection unit is connected to the side of the housing via a hinge structure to allow the protection unit to switch between an upward folded position and a downward unfolded position. A first fixing mechanism is provided between each of the protection units to achieve interlocking connection of adjacent protection sides when the protection unit is in the downward unfolded position; A second fixing mechanism is provided between each of the protection units and the side of the housing, so that the protection unit can be detachably fixed to the housing when it is in the upward folded position.

[0006] In one possible implementation, the first fixing mechanism includes an elastic buckle located on the side of the protection unit and a matching guide groove. When adjacent protection units are unfolded, they are interlocked by the elastic deformation of the buckle and the guide groove, and the inner wall of the guide groove is provided with an anti-detachment protrusion.

[0007] In one possible implementation, the hinge structure is a thin-walled movable hinge with a gradually varying thickness, where the thickness at the root is greater than the thickness at the end.

[0008] In one possible implementation, the second fixing mechanism includes a magnet embedded in the housing and a metal sheet protecting the inner side of the skirt, for adsorption and fixing when stored.

[0009] In one possible implementation, a buffer layer is provided on the inner side of the protection unit.

[0010] This utility model's technical solution achieves rapid switching between pin protection and installation states by setting a flip-up hinged protective unit on the circumferential side of the housing; at the same time, the interlocking structure of the elastic buckles and guide grooves between the protective units gives the protective frame impact resistance and mechanical strength, effectively resisting squeezing and vibration during transportation, while the magnetic fixing method improves the structural stability in the storage state, ultimately achieving the comprehensive benefits of extending pin life, reducing product return rate, and improving production assembly efficiency.

[0013] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0015] To address the problems in the background technology, this utility model proposes an LED digital tube with a pin 2 protection structure, including a housing 1 and pins 2 located at the bottom of the housing 1. A protection component 3 is provided on the circumferential side of the housing 1. The protection component 3 includes a plurality of protection units 31. Each protection unit 31 is connected to the side of the housing 1 through a hinge structure 4 to allow the protection unit 31 to switch between an upward folded position and a downward unfolded position. A first fixing mechanism 5 is provided between each of the protection units 31, which is used to achieve interlocking connection of adjacent protection sides when the protection unit 31 is in the downward unfolded position; A second fixing mechanism 6 is provided between each of the protection units 31 and the side of the housing 1, so that the protection unit 31 can be detachably fixed to the housing 1 when it is in the upward folded position.

[0016] Combined with reference Figures 1 to 2 As shown, in this embodiment, the LED digital tube includes a rectangular housing 1 and two rows of pins 2 vertically disposed at the bottom of the housing 1. The outer contour of the housing 1 is injection molded from ABS engineering plastic, and protective components 3 are evenly distributed circumferentially along its four sides. The protective components 3 consist of four independent elongated protective units 31, the length of each protective unit 31 matching the side of the housing 1, and the width being 1 / 3 of the height of the housing 1. The protective units 31 are connected to the side of the housing 1 via an integrally injection-molded thin-film hinge. The hinge axis is parallel to the extension direction of the side of the housing 1, allowing the protective units 31 to rotate 180° around the hinge axis, realizing the switching between the vertically folded-up storage position and the downward unfolded protective position.

[0017] When the protection unit 31 is in the downward unfolded position, the four protection units 31 form a rectangular protective frame around the bottom pin 2 area of ​​the housing 1. A first fixing mechanism 5 is provided at the mating end of adjacent protection units 31 to achieve mechanical interlocking between adjacent protection units 31. At this time, the four protection units 31 together form a closed protective frame. When it is necessary to store the protection unit 31, the operator releases the first fixing mechanism 5 from the lock on the adjacent protection unit 31, and then flips the protection unit 31 upwards to the side of the housing 1. A second fixing mechanism 6 is provided in the middle of each side of the housing 1. This second fixing mechanism 6 can be a snap-on type or a magnetic type, which can tightly fit the protection unit 31 against the side wall of the housing 1 when the protection unit 31 is flipped to the folded position. In other embodiments, the second fixing mechanism 6 can be omitted, and the protection unit 31 can be used to protect the pin 2 group of the digital tube during transportation. When using the digital tube, the protection unit 31 can also be cut along the active film hinge using a tool.

[0018] In one possible implementation, the first fixing mechanism 5 includes an elastic buckle 51 located on the side of the protection unit 31 and a matching guide groove 52. When the adjacent protection units 31 are unfolded, they are interlocked by the elastic deformation of the buckle and the guide groove 52, and the inner wall of the guide groove 52 is provided with an anti-detachment protrusion.

[0019] Combined with reference Figure 1 As shown, in this embodiment, the first fixing mechanism 5 consists of an elastic buckle 51 assembly integrated into the side wall of the protection unit 31 and a guide groove 52 system. The elastic buckle 51 is integrally injection molded from engineering plastic, with its root width gradually tapering towards the end, forming a wedge-shaped lock head at the end. Reinforcing ribs may also be provided on the back side to improve bending strength. The guide groove 52 extends along the width of the protection unit 31, with an inverted T-shaped cross-section and a guide slope at the entrance end to reduce assembly resistance. When adjacent protection units 31 are unfolded and connected, the operator pushes the protection unit 31 along the direction of the guide groove 52. After the wedge-shaped lock head of the elastic buckle 51 contacts the entrance slope of the guide groove 52, it undergoes radial elastic deformation until the lock head passes over the anti-detachment boss. At this point, the buckle springs back to reset, causing the lock head plane to fit tightly against the bottom plane of the boss, forming a bidirectional mechanical lock. To unlock, the buckle deforms by pressing the release window on the outside of the protection unit 31, and the protection unit 31 is simultaneously folded in the reverse direction to achieve separation.

[0020] In one possible implementation, the hinge structure 4 is a thin-walled movable hinge with a gradually varying thickness, where the thickness at the root is greater than the thickness at the end. Specifically, the hinge structure 4 is a thin-walled movable hinge with a gradually varying thickness, integrally injection molded from polypropylene material. The thickness at the connection between the root and the side wall of the housing 1 is 0.6-0.8 mm, and it linearly decreases along the extension direction of the protective unit 31 to a thickness of 0.2-0.3 mm at the end. The surface is provided with an evenly spaced arc-shaped corrugated structure.

[0021] In one possible implementation, the second fixing mechanism 6 includes a magnet 61 embedded in the housing 1 and a metal sheet 62 on the inner side of the protective skirt, used for adsorption and fixation in the stored state. Specifically, a rectangular magnet 61 groove is provided in the central area of ​​the side wall of the housing 1, and neodymium iron boron permanent magnets or metal sheets 62 are embedded in the groove, arranged in an array at intervals along the length of the side of the housing 1, with the magnetic pole direction perpendicular to the surface of the housing 1. A metal sheet 62 or a neodymium iron boron permanent magnet is provided on the inner side of the protective skirt corresponding to the position of the magnet 61 groove, and the surface of the metal sheet 62 is nickel-plated. When the protective skirt is flipped upward to the stored position, the metal sheet 62 and the magnet 61 groove form coplanar contact, and secondary mechanical limiting is achieved through the cooperation of the slot and elastic buckle 51 of the first fixing mechanism 5.

[0022] In one possible implementation, a buffer layer 7 is provided on the inner side of the protection unit 31. Specifically, to further optimize the protective performance, a silicone buffer layer 7 is attached to the inner surface of the protection unit 31, and its main body is made of silicone material through a molding process. In addition, the outer surface of the protection unit 31 is coated with an antistatic coating to effectively prevent the accumulation of static electricity from affecting the soldering terminals of the pins 2.
