Description

Technical Field

[0001] This utility model relates to the technical field of GX53 lamp holders, specifically a flat snap-fit ​​GX53 lamp holder structure. Background Technology

[0002] In the field of lighting engineering, the GX53 lamp holder is a core component connecting the lamp and the power supply. Its structural reliability directly affects the safety performance and service life of the lighting system. With the increasing demand for compact lamps in commercial lighting, home decoration and industrial scenarios, and for lamps designed for high-frequency vibration environments, the flat snap-on GX53 lamp holder has become the mainstream choice in the market due to its small size and easy assembly. However, the traditional structure has technical bottlenecks in terms of assembly accuracy, connection stability and vibration resistance.

[0003] In existing technologies, traditional GX53 lamp holders often employ single-column positioning or non-conical plug-in structures. During assembly, radial offset can easily lead to misalignment between the mating holes and the mating columns, causing poor contact. Snap-fit ​​structures often lack interference fit design or elastic compensation mechanisms, making them prone to fatigue and loosening of the elastic plate under high-frequency vibration environments. Actual measurements show that some products have insufficient snap-fit ​​strength, failing to meet vibration resistance requirements. Conductive sheet contact relies heavily on rigid limiting, lacking flexible buffer design. Assembly stress or long-term vibration can easily cause deformation of the conductive sheet, increasing contact resistance and affecting electrical connection stability. Furthermore, single-point or asymmetrical snap-fit ​​structures suffer from insufficient tensile strength, leading to structural separation under significant axial tension, making them unsuitable for complex operating conditions. These problems manifest as three major technical defects: low assembly precision, poor connection reliability, and weak vibration resistance. These directly result in increased lamp failure rates and shortened lifespans, becoming key pain points restricting industry development. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a flat snap-fit ​​GX53 lamp holder structure to solve the technical problems existing in the prior art mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flat snap-fit ​​GX53 lamp holder structure, including a first lamp housing and a second lamp housing, wherein the first lamp housing has a tapered docking hole, and the second lamp housing has a docking post that matches the tapered shape of the docking hole; When the first lamp housing and the second lamp housing are combined, the mating post and the mating hole form a self-aligning insertion state through the conical surface cooperation, thereby achieving axial positioning; The second lamp housing is provided with an elastic plate, and the first lamp housing is provided with a snap-fit ​​insertion hole; When merging, the elastic plate is snapped into the snap-fit ​​hole through elastic deformation to form a snap-fit ​​fixation, and there is an interference fit between the mating surface of the elastic plate and the snap-fit ​​hole. Preferably, four docking posts are provided on the second lamp housing, and the four docking posts are equidistantly distributed along the circumference of the second lamp housing; The first lamp housing has four corresponding docking holes, and the positions of the four docking holes correspond one-to-one with the docking posts and have the same taper. Preferably, the second lamp housing is provided with a mounting base, the elastic plate is integrally formed on the mounting base, and the elastic plate is provided with two snap-fit ​​connectors of different lengths; Among them, the short snap-fit ​​connector has an arc transition section at the end, and the long snap-fit ​​connector has a reinforcing rib structure at the root.

[0010] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0011] The embodiments of this utility model will be described below based on its overall structure.

[0012] Example Please see Figures 1-5 This utility model provides a technical solution: a flat snap-fit ​​GX53 lamp holder structure, including a first lamp housing 1 and a second lamp housing 2. The first lamp housing 1 has a tapered docking hole 12, and the second lamp housing 2 has a docking post 22 that matches the tapered shape of the docking hole 12. This tapered fit enables self-correction of assembly deviation, improves positioning accuracy, and avoids poor contact caused by radial offset during assembly.

[0013] When the first lamp housing 1 and the second lamp housing 2 are combined, the mating post 22 and the mating hole 12 form a self-aligning insertion state through the conical surface cooperation, realizing axial positioning; the self-aligning characteristic makes assembly without calibration tools, ensuring the precise meshing of the subsequent snap-fit ​​structure.

[0014] The second lamp housing 2 is provided with an elastic plate 231, and the first lamp housing 1 is provided with a snap-fit ​​insertion hole; the interference fit of the mating surface ensures the vibration resistance after snap-fit ​​and improves the structural reliability.

[0015] When the two are combined, the elastic plate 231 is snapped into the snap-fit ​​hole through elastic deformation to form a snap-fit ​​fixation, and there is an interference fit between the mating surface of the elastic plate 231 and the snap-fit ​​hole; the interference fit design makes the elastic plate 231 generate a continuous pre-tightening force to prevent loosening under high frequency vibration and meet the vibration resistance requirements of GX53 lamps.

[0016] Furthermore, four connecting posts 22 are provided on the second lamp housing 2, and the four connecting posts 22 are equidistantly distributed along the circumference of the second lamp housing 2; the equidistant distribution of the four connecting posts 22 forms a uniform stress structure, avoids local stress concentration, improves the overall tensile strength, and extends the structural life.

[0017] The first lamp housing 1 has four corresponding mating holes 12. The positions of the four mating holes 12 correspond one-to-one with the mating posts 22 and have the same taper. The consistent taper ensures full contact of the mating surfaces, reduces assembly friction resistance, improves assembly efficiency, and reduces operator fatigue.

[0018] Furthermore, a mounting base 23 is provided on the second lamp housing 2, and an elastic plate 231 is integrally formed on the mounting base 23. The elastic plate 231 is provided with two snap-fit ​​connectors 232 of different lengths. The integrally formed structure eliminates assembly gaps and improves structural rigidity. The double snap-fit ​​connector design adapts to different assembly tolerances and enhances snap-fit ​​adaptability.

[0019] The short snap-fit ​​connector 232 has a rounded transition section at its end, while the long snap-fit ​​connector 232 has a reinforcing rib structure at its root. The rounded transition section reduces assembly scratch damage, and the reinforcing rib increases the bending stiffness of the long snap-fit ​​connector 232, preventing deformation and failure after long-term use.

[0020] Furthermore, when the first lamp housing 1 and the second lamp housing 2 are in a combined state, the short snap-fit ​​connector 232 directly snaps into the snap-fit ​​hole on the first lamp housing 1; the direct snap-fit ​​enables rapid fixing, shortens the assembly time to within 5 seconds, improves production efficiency, and ensures accurate positioning of the short snap-fit ​​connector.

[0021] A mounting spring 3 is engaged between the long snap-fit ​​connector 232 and the first lamp housing 1 to provide preload force; the mounting spring 3 provides continuous preload force to prevent loosening and improve durability.

[0022] Furthermore, four mounting bases 23 are provided, which are symmetrically distributed along the circumference of the second lamp housing 2; the symmetrical distribution of the four bases evenly distributes the load, avoids local overload, and improves the vibration resistance of the structure.

[0023] Furthermore, two conductive sheets 11 are symmetrically arranged on the first lamp housing 1; the low resistance characteristic reduces heat generation and improves electrical efficiency, and the symmetrical arrangement ensures uniform current distribution and avoids local overheating.

[0024] Two elastic limit brackets 21 are correspondingly provided on the second lamp housing 2. The positions of the two elastic limit brackets 21 correspond to the axial projection of the conductive sheet 11. The axial projection correspondence ensures accurate alignment, improves the stability of electrical connection, and reduces the failure rate.

[0025] Each elastic limit frame 21 is provided with an abutment plate 211; the abutment plate 211 can be made of PC+ABS composite material, which provides uniform pressure distribution, ensures that the conductive sheet 11 is in close contact, and protects the conductive sheet 11 from mechanical damage, thus extending its service life.

[0026] When the first lamp housing 1 and the second lamp housing 2 are combined, the elastic limiting frame 21 is located outside the conductive sheet 11, and the abutment plate 211 forms a flexible abutment with the outside of the conductive sheet 11; the flexible abutment absorbs assembly stress and vibration impact, avoids deformation or damage to the conductive sheet 11 caused by hard contact, and improves the durability of electrical connection.

[0027] Furthermore, the first lamp housing 1 is provided with a plug-in plate 13, and the second lamp housing 2 is provided with a plug-in groove 24 that matches the cross section of the plug-in plate 13; the cross section matching design forms a stable plug-in structure, enhances axial tensile strength, prevents accidental separation of the structure after merging, and improves safety.

[0028] When the first lamp housing 1 and the second lamp housing 2 are combined, the plug plate 13 and the plug slot 24 form a dovetail-shaped plug structure, which enhances the axial tensile strength. The dovetail-shaped structure improves the axial tensile strength through the self-locking effect, effectively resists external pulling force, and ensures the structural integrity under high-frequency vibration environment.

[0029] The working process of the flat snap-fit ​​GX53 lamp holder structure is as follows: First, the first lamp housing 1 and the second lamp housing 2 are axially positioned and merged; the four docking posts 22 on the second lamp housing 2 are equidistantly distributed along the circumferential direction, and their taper is precisely matched with the four tapered docking holes 12 on the first lamp housing 1; during the merging, the docking posts 22 automatically correct the radial offset through the tapered surface fit, and form a self-aligning insertion state with the docking holes 12 to achieve precise axial positioning; Subsequently, the elastic snap-fit ​​fixing is completed; four mounting seats 23 are symmetrically arranged on the second lamp housing 2. The elastic plate 231 of each mounting seat 23 is integrally formed and snaps into the snap-fit ​​insertion hole of the first lamp housing 1 through elastic deformation. The interference of the mating surface ensures the reliability of the snap-fit; the short snap-fit ​​connector 232 on the elastic plate 231 has a rounded transition part at the end that directly snaps into the snap-fit ​​insertion hole, and the reinforcing rib structure at the root of the long snap-fit ​​connector 232 snaps into the mounting spring 3. The mounting spring 3 provides subsequent pre-tightening force, forming a double snap-fit ​​fixing; Next, the conductive sheet 11 is made into flexible contact; the conductive sheet 11 symmetrically arranged on the first lamp housing 1 corresponds to the axial projection of the elastic limiting frame 21 on the second lamp housing 2; when they are combined, the elastic limiting frame 21 is located outside the conductive sheet 11, and the abutting plate 211 inside it forms a flexible abutment with the outside of the conductive sheet 11. Finally, the tensile strength of the structure is enhanced; the T-shaped cross-section plug plate 13 on the first lamp housing 1 and the plug groove 24 on the second lamp housing 2 form a dovetail plug structure, and the axial tensile strength is improved through cross-section matching; this structure works in conjunction with the preceding positioning-clamping composite structure to make the entire lamp holder form a stable mechanical connection system after assembly, which meets the usage requirements of GX53 lamps in high-frequency vibration environment.
