Abstract
Description
Technical Field
[0001] The invention relates to the field of lamps, and in particular to an isolated lamp holder. Background Art
[0002] The double-ended lamp holders in the prior art, such as ZL201820203818.7, a ceramic lamp holder for fixing double-ended lamps, have wire clamping springs that are directly electrically connected to the ballast through the lead holes of the base. This connection method makes it easy for safety accidents such as electric shock to occur during the installation of the lamp body, and cannot effectively protect the personal safety of operators. It also does not meet international safety regulations, resulting in restrictions on product exports to overseas markets. Summary of the invention
[0003] The present invention overcomes the disadvantages of the prior art that a double-ended lamp holder uses a wire clamping spring to directly connect the ballast, which may easily cause safety accidents such as electric shock to human body during installation, and provides an isolated lamp holder.
[0004] The technical solution adopted by the present invention to achieve the purpose of the invention is: an isolation type lamp holder, including a base and an upper cover, the base is provided with a wire clamping spring and a lamp body limiting spring, the base is slidably connected to the upper cover, and also includes a metal spring connected to the ballast, the base is provided with a metal spring mounting groove, the metal spring is fixedly installed in the metal spring mounting groove and electrically connected to the ballast, the bottom surface of the upper cover is provided with a protrusion that pushes the metal spring, the base and the upper cover form a structure in which the protrusion of the upper cover pushes the metal spring to contact the wire clamping spring.
[0005] Furthermore, the wire clamping spring comprises: a strip-shaped clamping portion cooperating with the wire pin of the lamp body and a sheet-shaped contact portion cooperating with the metal spring, and the sheet-shaped contact portion is arranged at one end of the strip-shaped clamping portion corresponding to the metal spring.
[0006] Furthermore, a bending portion is provided at the upper end of the metal spring sheet, one side of the bending portion is a contact surface of the protrusion, and the other side of the bending portion is a contact surface of the wire clamping spring sheet.
[0007] The beneficial effect of the present invention is that when the upper cover of the lamp holder of the present invention is not pushed tightly, the metal spring piece and the wire clamping spring piece are not connected, which can effectively protect the personal safety of the operator when the lamp body is installed, improve the safety performance of the product, meet international safety regulations, and facilitate the export of products to overseas markets.

DETAILED DESCRIPTION
[0016] As shown in the accompanying drawings, an isolated lamp holder of this embodiment includes a base 1 and an upper cover 2. A sliding groove is provided on the side wall of the base 1, and the base 1 is slidably connected to the upper cover 2. The base 1 is provided with a wire clamping spring 1-1 and a lamp body limiting spring 1-2. The wire clamping spring 1-1 is used to clamp the wire pin of the double-ended lamp, and the lamp body limiting spring 1-2 is used to clamp the side of the double-ended lamp. The base 1 also includes a metal spring 1-3 connected to the ballast. The base 1 is provided with a metal spring installation groove 1-4, and the metal spring 1-3 is fixedly installed in the metal spring installation groove 1-4 and electrically connected to the ballast. The bottom surface of the upper cover 2 is provided with a protrusion 2-1 that pushes the metal spring 1-3, and the base 1 and the upper cover 2 form a structure in which the protrusion 2-1 of the upper cover 2 pushes the metal spring 1-3 to contact the wire clamping spring 1-1. When the upper cover 2 is installed in place, the metal spring 1-3 is electrically connected to the wire clamping spring 1-1.
[0017] In order to facilitate the contact between the metal spring 1-3 and the clamping spring 1-1, the clamping spring 1-1 preferably in this embodiment includes: a strip clamping portion 1-1-1 that cooperates with the wire pin of the lamp body and a sheet contact portion 1-1-2 that cooperates with the metal spring. The strip clamping portion 1-1-1 and the sheet contact portion 1-1-2 are an integrally formed structure, and the sheet contact portion 1-1-2 is arranged at one end of the strip clamping portion 1-1-1 corresponding to the metal spring 1-3. The upper end of the metal spring 1-3 preferably in this embodiment is provided with a bending portion, one side of the bending portion is a convex block contact surface 1-3-1, and the other side of the bending portion is a clamping spring contact surface 1-3-2. When the metal spring sheet 1-3 is deformed under the pressure of the bump 2-1, the bump contact surface 1-3-1 of the metal spring sheet 1-3 contacts the bump 2-1, and the wire clamping spring sheet contact surface 1-3-2 of the metal spring sheet 1-3 contacts the sheet-shaped contact portion 1-1-2 of the wire clamping spring sheet 1-1.
[0018] When the lamp body is actually installed, the wire pin of the double-ended lamp is inserted into the gap of the wire clamping spring piece 1-1 of the base 1, and the lamp body limiting spring piece 1-2 of the base 1 clamps the side of the double-ended lamp. After the upper cover 2 is docked with the base 1, the upper cover 2 is pushed to slide along the base 1. During the sliding process, the upper cover 2 gathers the wire clamping spring piece 1-1 so that the wire clamping spring piece 1-1 is fully in contact with the wire pin of the double-ended lamp. The upper cover 2 continues to slide forward, the protrusion 2-1 contacts the protrusion contact surface 1-3-1 of the metal spring 1-3, and pushes the metal spring 1-3 to deform and approach the sheet contact portion 1-1-2 of the clamping spring 1-1. When the upper cover 2 is installed in place, the clamping spring contact surface 1-3-2 of the metal spring 1-3 contacts the sheet contact portion 1-1-2 of the clamping spring 1-1, and the wire pin of the double-ended lamp is electrically connected to the ballast through the clamping spring 1-1 and the metal spring 1-3, and the lamp body is installed. When the double-ended lamp needs to be replaced, the upper cover 2 is moved in the opposite direction, the metal spring 1-3 is reset, and the contact with the sheet contact portion 1-1-2 of the clamping spring 1-1 is disconnected, and the electrical connection circuit between the wire pin of the double-ended lamp and the ballast is disconnected, and the operation can be safe. During the installation process of this embodiment, only when the upper cover 2 is installed in place, the wire pins of the double-ended lamp can be connected to the ballast, ensuring the personal safety of the staff during the operation and improving the safety performance of the product.
