Description

A type of G13 lamp holder Technical Field

[0001] This utility model relates to a lamp holder, and more particularly to a G13 lamp holder. Background Technology

[0002] The G13 lamp holder is currently the most common and widely used interface component for installing lamp tubes. Since it is connected to mains power, it's uncertain whether the wiring is live during installation. Therefore, installing it while powered on may pose a safety hazard to installers. To ensure the safety of installers, a blocking button is installed on the lamp holder. When the lamp holder is powered on, this blocking button insulates and separates two conductive components inside the lamp holder (such as the short-circuit copper plate and the metal conductive spring), thus providing a blocking function and ensuring the safety of installers. However, in current G13 lamp holders with blocking functions, the blocking button is not securely installed. It can either be easily pulled out or is loose, making it easy for it to detach from the lamp holder due to accidental operation or slight external force, thus rendering the blocking function ineffective. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a G13 lamp holder with a simple structure and stable blocking function.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A G13 lamp holder includes a lamp holder body and a blocking button mounted on the lamp holder body for insulatingly separating two conductive components installed inside the lamp holder body. The blocking button includes an exposed operating part located outside the lamp holder body and an insertion blocking part extending into the lamp holder body. The lamp holder body has a corresponding mounting port for the insertion blocking part to extend into the lamp holder body and be installed inside the lamp holder body. The mounting port communicates with the inner cavity of the lamp holder body. The insertion blocking part includes a partition part and a positioning mounting part. The partition part is used to provide insulation between the two conductive components. An anti-disengagement limiting mechanism is provided between the positioning mounting part and the lamp holder body.

[0006] The lamp head body has a first mounting sidewall and a second mounting sidewall arranged opposite to each other. The mounting opening is provided between the first mounting sidewall and the second mounting sidewall. The anti-detachment limiting mechanism is provided between the positioning mounting part and the second mounting sidewall.

[0007] The positioning and mounting part has a positioning rib protruding towards the second mounting sidewall, and the anti-disengagement limiting mechanism is a limiting protrusion protruding on the positioning rib and protruding towards the second mounting sidewall. The limiting protrusion cooperates with the second mounting sidewall to form an anti-disengagement limiting for the blocking button.

[0008] There are two positioning ribs, which are spaced apart. Each positioning rib has a limiting protrusion. The partition is located between the two positioning ribs.

[0009] The end face on the second mounting side wall that mates with the limiting protrusion is an anti-detachment limiting surface. A positioning groove is recessed on the anti-detachment limiting surface for the limiting protrusion to be embedded in. When the partition is completely pulled away from the two conductive components, that is, when the two guide components are in a state of contact and conduction, the limiting protrusion is embedded in the positioning groove.

[0010] The end of the positioning rib away from the exposed operating portion has a first inclined guide end face that is inclined toward the second mounting sidewall in the direction of the exposed operating portion.

[0011] The end of the limiting protrusion away from the exposed operating portion has a second inclined guide end face that is inclined toward the second mounting sidewall in the direction of the exposed operating portion.

[0012] The corresponding end face of the partition is provided with multiple anti-slip positioning ribs, which are spaced apart.

[0013] The two conductive components are a short-circuit copper sheet and a metal conductive spring sheet installed inside the lamp holder body, respectively. The anti-slip positioning rib is provided on the end face of the partition corresponding to the metal conductive spring sheet.

[0014] The mounting opening is provided with a support bracket to support the inserted blocking portion.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] (1) By setting an anti-detachment limiting mechanism between the positioning and mounting part of the blocking button and the lamp holder body, the blocking button cannot be easily detached due to misoperation or external force after being installed on the lamp holder body, ensuring that the insulation barrier is always maintained during the power-on installation process, fundamentally solving the problem of the insulation barrier failure caused by the loosening or direct detachment of the traditional blocking button, thereby improving safety.

[0017] (2) The blocking button has a clear division of labor. The part that extends into the blocking section is clearly divided into a barrier part, which is used to insulate and isolate the conductive parts, and a positioning and mounting part, which is used to fix and prevent it from falling off, thus making it more reliable.

[0018] (3) The exposed operating part retains the operability of the external blocking button, and the installer can still manually control the blocking state, but the internal anti-dislodgement design prevents accidental failure. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] As shown in the figure, a G13 lamp holder includes a lamp holder body 1 and a blocking button 2 installed on the lamp holder body 1 to insulate and separate two conductive components installed inside the lamp holder body 1. The blocking button 2 includes an exposed operating part 201 located outside the lamp holder body 1 and an insertion blocking part 202 extending into the lamp holder body 1. The lamp holder body 1 is correspondingly provided with an installation port 10 for the insertion blocking part 202 to extend into the lamp holder body 1 and be installed inside the lamp holder body 1. The installation port 10 is connected to the inner cavity of the lamp holder body 1. The insertion blocking part 202 includes a partition part 21 and a positioning installation part 22. The partition part 21 is used to provide insulation between the two conductive components. An anti-disengagement limiting mechanism is provided between the positioning installation part 22 and the lamp holder body 1.

[0028] In this specific embodiment, the lamp holder body 1 has a first mounting sidewall 11 and a second mounting sidewall 12 arranged opposite to each other. A mounting opening 10 is provided between the first mounting sidewall 11 and the second mounting sidewall 12. An anti-detachment limiting mechanism is provided between the positioning mounting part 22 and the second mounting sidewall 12. The anti-detachment limiting mechanism is directly linked to the mounting sidewall, making the overall structure relatively simple and achieving stable connection and installation through a simple structure.

[0029] In this specific embodiment, the positioning mounting part 22 has a positioning rib 221 protruding towards the second mounting sidewall 12, and the anti-disengagement limiting mechanism is a limiting protrusion 222 protruding from the positioning rib 221 towards the second mounting sidewall 12. The limiting protrusion 222 cooperates with the second mounting sidewall 12 to form an anti-disengagement limiting mechanism for the blocking button 2. The above-mentioned anti-disengagement limiting mechanism has a simple structure. The contact limiting formed by the cooperation of the limiting protrusion 222 and the second mounting sidewall 12 requires no additional parts, reduces costs, and has high reliability.

[0030] In this specific embodiment, there are two positioning ribs 221, which are spaced apart. Each positioning rib 221 has a protruding limiting protrusion 222, and a partition 21 is disposed between the two positioning ribs 221. The symmetrical layout of the double positioning ribs 221 ensures balanced force distribution and avoids deformation caused by stress concentration on one side. The partition 21 is centrally located and protected by the positioning ribs 221 on both sides, improving the stability of the insulating partition.

[0031] In this specific embodiment, the end face on the second mounting sidewall 12 that mates with the limiting protrusion 222 is an anti-detachment limiting surface 121. The anti-detachment limiting surface 121 has a recessed positioning groove 122 for the limiting protrusion 222 to embed into. When the partition 21 is completely withdrawn from between the two conductive components, i.e., when the two guide components are in a contact and conductive state, the limiting protrusion 222 is embedded in the positioning groove 122. This provides clear position feedback, making the conduction or blocking state perceptible.

[0032] In this specific embodiment, the end of the positioning rib 221 away from the exposed operating portion 201 has a first oblique guide end face 2211 that is inclined toward the second mounting sidewall 12 in the direction of the exposed operating portion 201. The oblique guide facilitates blocking the insertion of the button 2 into the mounting port 10, reducing assembly resistance; it also avoids breakage of the positioning rib 221 due to hard impact, thus improving assembly efficiency.

[0033] In this specific embodiment, the end of the limiting protrusion 222 away from the exposed operating portion 201 has a second inclined guide end face 2221 that is inclined toward the second mounting sidewall 12 in the direction of the exposed operating portion 201. This, in conjunction with the first inclined guide end face 2211, reduces assembly resistance.

[0034] In this specific embodiment, multiple anti-slip positioning ribs 211 are raised on the corresponding end face of the partition 21, and the multiple anti-slip positioning ribs 211 are spaced apart. The anti-slip positioning ribs 211 structure increases the friction coefficient of the contact surface between the partition 21 and the metal conductive spring 4, preventing the blocking button 2 from accidentally slipping during installation or vibration, and ensuring the stability and reliability of the blocking state.

[0035] In this specific embodiment, the two conductive components are a short-circuit copper sheet 3 and a metal conductive spring sheet 4 installed in the lamp holder body 1, and an anti-slip positioning rib 211 is provided on the end face of the partition part 21 corresponding to the metal conductive spring sheet 4.

[0036] In this specific embodiment, a support bracket 101 is provided inside the mounting port 10 to support the inserted blocking portion 202. This ensures the stable installation of the blocking button 2 on the lamp holder body 1.

[0037] In the energized installation state, the partition 21 extends between the two conductive components (short-circuit copper sheet 3 and metal conductive spring sheet 4). At this time, the blocking state is mainly maintained by the elasticity of the metal conductive spring sheet 4 against the corresponding end face of the partition 21, in conjunction with the anti-slip positioning rib 211, to achieve stable blocking. After installation, by applying force to the exposed operating part 201, the extended blocking part 202 is pulled outward. When the limiting protrusion 222 is embedded in the positioning groove 122, the partition 21 is completely withdrawn from between the two conductive components, realizing conduction.
