Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a non-sealed bulb holder. Background Technology

[0002] To protect automotive bulbs, the mounting end of the bulb in the bulb holder is typically connected to the lampshade via a clip. To facilitate this connection, a separately designed mounting handle is usually first connected to the bulb holder's connecting handle, and then the mounting end of the bulb holder is connected to the lampshade clip by tightening the mounting handle. This not only requires the separate manufacture and processing of the mounting handle but also necessitates its disassembly and reassembly during bulb assembly, resulting in slow assembly speed and low efficiency. Therefore, using existing bulb holders for installing automotive bulbs is not only inefficient but also requires the separate design and manufacture of the mounting handle, leading to low installation efficiency and high cost. Utility Model Content

[0003] To improve the installation efficiency and reduce the installation cost of automotive bulbs, this invention proposes a non-sealed bulb holder. The non-sealed bulb holder includes a base and metal terminals. The base includes a mounting end, a positioning plate, and a connecting handle. The mounting end and the connecting handle are located on opposite sides of the positioning plate, and the length L1 of the connecting handle is at least twice the length L2 of the mounting end. The mounting end has a bulb insertion slot, and the connecting handle has a wire-passing slot. A terminal slot is provided at the connection point between the mounting end and the connecting handle, and the bulb insertion slot and the wire-passing slot communicate through the terminal slot. The metal terminal is inserted into the terminal slot. When assembling the non-sealed bulb holder with the lampshade, the assembler only needs to hold the connecting handle and twist it, making the operation simple, convenient, and efficient. Furthermore, this non-sealed bulb holder eliminates the need for a separately designed and manufactured assembly handle. Therefore, using this non-sealed bulb holder can effectively improve the installation efficiency and reduce the installation cost of automotive bulbs.

[0004] Preferably, the connecting handle has assembly guide grooves on both sides. This way, after the non-sealed bulb holder and lamp cover are assembled, when connecting the accessory to the connecting handle, the retaining strip on the accessory can be inserted into the assembly guide groove. This facilitates the connection between the accessory and the connecting handle, and also allows the assembly guide groove and the retaining strip on the accessory to position the connecting handle, preventing the non-sealed bulb holder from shifting due to vibration during vehicle operation, or even detaching from the lamp cover, thus affecting vehicle safety.

[0005] Preferably, the side walls on both sides of the bulb insertion slot are provided with clearance grooves. This allows the clearance grooves to position the bulb during installation into the non-sealed bulb holder, improving assembly efficiency. Furthermore, the inner wall of the bulb insertion slot is provided with bulb-limiting protrusions, located on both sides of the clearance grooves. This allows the bulb-limiting protrusions to hold the bulb in place during installation, preventing it from shifting and affecting its use.

[0006] Preferably, a connecting buckle is provided on the outer wall of the mounting end, the position of which corresponds to the position of the clearance groove, and a positioning protrusion is provided on the snap-fit ​​surface of the connecting buckle. Thus, when the non-sealed bulb holder of this invention is connected to the lampshade, the positioning protrusion on the snap-fit ​​surface of the connecting buckle can cooperate with the corresponding groove on the lampshade to position the non-sealed bulb holder on the lampshade. In other words, when the positioning protrusion on the connecting buckle engages with the corresponding groove on the lampshade, it indicates that the non-sealed bulb holder is properly assembled with the lampshade, improving assembly efficiency and preventing the non-sealed bulb holder from detaching from the lampshade. Furthermore, a positioning ridge is provided on the outer wall of the mounting end, and this positioning ridge is close to the connecting buckle. In this way, when assembling the non-sealed bulb holder and the lampshade of this utility model, the positioning ridge can be used for positioning, preventing the non-sealed bulb holder from being over-tightened, which would prevent the connecting buckle on the non-sealed bulb holder from connecting with the lampshade buckle and affect the assembly effect.

[0007] Preferably, the inner wall of the terminal slot is provided with a barb positioning groove for mounting the positioning barbs on the metal terminal. This allows the positioning barbs on the metal terminal to engage with the barb positioning groove on the inner wall of the terminal slot when the metal terminal is assembled into the non-sealed bulb holder of this invention. The positioning barbs on the metal terminal and the barb positioning groove on the inner wall of the terminal slot work together to position the metal terminal, preventing it from falling out of the terminal slot and affecting the electrical connection between the non-sealed bulb holder and the automotive bulb, and even the use of the automotive bulb, thus impacting vehicle safety. Furthermore, the positioning barbs are located on a positioning piece between two opposing end clips on the metal terminal, and the positioning piece has protective side edges on both sides. This protective side edges on both sides of the positioning piece between the two opposing end clips prevent the side edges of the positioning piece from scratching the inner wall of the base during assembly, thus preventing damage to the base. It also ensures the stability of the metal terminal installation in the terminal slot while maintaining the design requirements for the gap between the positioning piece and the slot wall. More preferably, the metal terminal is provided with a limiting protrusion located between the positioning barb and the wiring end of the metal terminal; the inner wall of the terminal groove is provided with a limiting groove for mounting the limiting protrusion, and the limiting groove and the barb positioning groove are arranged opposite to each other in the extension direction along the central axis of the mounting end. Thus, when the metal terminal is assembled into the terminal groove in the base, the limiting protrusion on the metal terminal is engaged in the limiting groove on the inner wall of the terminal groove, thereby further improving the installation stability of the metal terminal in the terminal groove by utilizing the cooperation between the limiting protrusion and the limiting groove.

[0008] Preferably, the positioning plate is provided with a through-glue groove, and the through-glue groove is located on both sides of the connecting handle. In this way, providing a through-glue groove on the positioning plate can not only avoid glue leakage problems during injection molding of the base, but also prevent uneven wall thickness of the connecting handle of the injection molded base, or even shrinkage problems, which would affect the yield of the injection molded base.

[0013] Below, in conjunction with Figures 1 to 4 This invention provides a detailed description of the non-sealed bulb holder.

[0014] like Figures 1 to 4As shown, the non-sealed bulb holder of this utility model includes a base 1 and metal terminals 2. The base 1 includes a mounting end 11, a positioning plate 12, and a connecting handle 13. The mounting end 11 and the connecting handle 13 are located on opposite sides of the positioning plate 12, and the length L1 of the connecting handle 13 is at least twice the length L2 of the mounting end 11. The mounting end 11 is provided with a bulb insertion slot 111, and the connecting handle 13 is provided with a wire-passing slot 131. A terminal slot (not shown in the figure) is provided at the connection point between the mounting end 11 and the connecting handle 13, and the bulb insertion slot 111 and the wire-passing slot 131 communicate through the terminal slot. The metal terminals 2 are inserted into the terminal slots. Preferably, assembly guide grooves 132 are provided on both sides of the connecting handle 13. Thus, after the non-sealed bulb holder and lampshade of this utility model are assembled together, when connecting the accessory and the connecting handle 13, the retaining strip on the accessory can be inserted into the assembly guide groove 132. This facilitates the connection between the accessory and the connecting handle 13, and also allows the connecting handle 13 to be positioned using the assembly guide groove 132 and the retaining strip on the accessory (not shown in the figure). This prevents the non-sealed bulb holder of this utility model from becoming misaligned due to vibration during vehicle operation, or even falling off the lampshade, affecting vehicle driving safety. Preferably, the positioning piece 12 is provided with a through-glue groove 121, and the through-glue groove 121 is located on both sides of the connecting handle 13. Thus, providing the through-glue groove 121 on the positioning piece 12 can prevent through-glue problems during injection molding of the base 1, and can also prevent uneven wall thickness of the connecting handle 13 of the injection molded base 1, or even shrinkage problems, affecting the yield of the injection molded base 1. Preferably, clearance grooves 112 are provided on the side walls on both sides of the bulb insertion slot 111. Thus, when assembling the automotive bulb 3 into the non-sealed bulb holder of this invention, the insertion direction of the automotive bulb 3 can be positioned using the clearance groove 112, improving assembly efficiency. Preferably, a bulb limiting protrusion 1111 is provided on the inner wall of the bulb insertion groove 111, and the bulb limiting protrusion 1111 is located on both sides of the clearance groove 112. Thus, when assembling the automotive bulb 3 into the non-sealed bulb holder of this invention, the bulb limiting protrusion 1111 can be used to hold the automotive bulb 3 in place, preventing the automotive bulb 3 from shaking and affecting its use. Preferably, a connecting buckle 113 is provided on the outer wall of the mounting end 11, the position of the connecting buckle 113 corresponds to the position of the clearance groove 112, and a positioning protrusion 1131 is provided on the snap-fit ​​surface of the connecting buckle 113. Thus, when the non-sealed bulb holder of this utility model is connected to the lampshade, the positioning protrusion 1131 on the snap-fit ​​surface of the connecting buckle 113 can be used to cooperate with the corresponding groove on the lampshade (not shown in the figure) to position the non-sealed bulb holder of this utility model on the lampshade. That is to say, when the positioning protrusion 1131 on the connecting buckle 113 is snapped into the corresponding groove on the lampshade, it means that the non-sealed bulb holder of this utility model is properly assembled when connected to the lampshade, which improves the assembly efficiency and at the same time prevents the non-sealed bulb holder of this utility model from falling off the lampshade.Preferably, a positioning ridge 114 is provided on the outer wall of the mounting end 11, and the positioning ridge 114 is close to the connecting buckle 113. In this way, when assembling the non-sealed bulb holder and the lampshade, the positioning ridge 114 can be used for positioning, preventing the non-sealed bulb holder from being over-tightened, which would prevent the connecting buckle on the non-sealed bulb holder from connecting with the lampshade buckle and affect the assembly effect. Preferably, a barb positioning groove 115 for mounting the positioning barbs 21 on the metal terminal 2 is provided on the inner wall of the terminal slot. Thus, when the metal terminal 2 is assembled into the non-sealed bulb holder of this invention, the positioning barbs 21 on the metal terminal 2 can be engaged in the barb positioning grooves 115 on the inner wall of the terminal slot. That is, the positioning barbs 21 on the metal terminal 2 and the barb positioning grooves 115 on the inner wall of the terminal slot cooperate to position the metal terminal 2, preventing the metal terminal 2 from falling out of the terminal slot and affecting the electrical connection between the non-sealed bulb holder and the automotive bulb, and even the use of the automotive bulb, thus affecting vehicle driving safety. Preferably, the positioning barbs 21 are located on the positioning pieces 23 between the two opposing end clips 22 on the metal terminal 2, and the positioning pieces 23 have protective side edges 231 on both sides. Thus, protective sidewalls 231 are provided on both sides of the positioning piece 23 located between the two opposing end bullet pieces 22. This not only prevents the side edges of the positioning piece 23 from scratching the inner wall of the base 1 during assembly and causing damage to the base 1, but also ensures the installation stability of the metal terminal 2 in the terminal slot while meeting the design requirements for the gap between the positioning piece 23 and the slot wall. When producing the metal terminal 2 in the non-sealed bulb holder of this utility model, the protective sidewalls 231 can be formed simply by bending the side of the positioning piece 23, which is simple and convenient and can reduce the production cost of the metal terminal 2. Preferably, the metal terminal 2 is provided with a limiting protrusion 24, which is located between the positioning barb 21 and the wiring end 25 of the metal terminal 2; the inner wall of the terminal slot is provided with a limiting groove 133 for installing the limiting protrusion 24, and the limiting groove 133 and the barb positioning groove 115 are opposite to each other in the extension direction along the central axis of the mounting end 11. Thus, when the metal terminal 2 is assembled into the terminal slot in the base 1, the limiting protrusion 24 on the metal terminal 2 is engaged in the limiting groove 133 on the inner wall of the terminal slot, thereby further improving the installation stability of the metal terminal 2 in the terminal slot by utilizing the cooperation between the limiting protrusion 24 and the limiting groove 115. Preferably, the end spring piece 22 of the metal terminal 2 is provided with a clamping bend 221, and the clamping bend 221 is close to the free end of the end spring piece 22. Thus, when the automotive bulb is installed into the non-sealed bulb holder of this utility model, the clamping bends 221 on the two end spring pieces 22 of the metal terminal 2 are located on both sides of the filament of the automotive bulb 3 and clamp the filament, which can effectively increase the contact area between the metal terminal 2 and the filament of the automotive bulb 3, ensuring that the metal terminal 2 and the filament are in full contact.

[0015] When assembling the non-sealed bulb holder of this invention with the lampshade (not shown in the figure), the assembler only needs to hold the connecting handle 13 and turn it, making the operation simple, convenient, and efficient. Furthermore, the non-sealed bulb holder of this invention does not require a separately designed and manufactured assembly handle. Therefore, using the non-sealed bulb holder of this invention can effectively improve the installation efficiency of automotive bulbs 3 and reduce the installation cost of automotive bulbs 3.
