Detailed ways

As shown in the drawings, an isolated lamp holder of this embodiment includes a base 1 and an upper cover 2 , a slide groove is provided on the side wall of the base 1 , and the base 1 and the upper cover 2 are slidably connected. The base 1 is provided with clamping shrapnel 1-1 and lamp body limiting shrapnel 1-2. The side of the double-ended lamp. The base 1 also includes a metal shrapnel 1-3 communicating with the ballast. The base 1 is provided with a metal shrapnel installation groove 1-4, and the metal shrapnel 1-3 is fixedly installed in the metal shrapnel installation groove 1-4 and electrically connected with the ballast. The bottom surface of the upper cover 2 is provided with a bump 2-1 that pushes the metal shrapnel 1-3, and the base 1 and the upper cover 2 form the bump 2-1 of the upper cover 2 to push the metal shrapnel 1-3 into contact with the clamping shrapnel 1-1 Structure. When the upper cover 2 is installed in place, the metal shrapnel 1-3 is electrically connected to the clamping shrapnel 1-1.

In order to facilitate the contact between the metal shrapnel 1-3 and the clamping shrapnel 1-1, the preferred clamping shrapnel 1-1 in this embodiment includes: a strip-shaped clamping part 1-1-1 that cooperates with the wire needle of the lamp body and a metal The sheet-shaped contact part 1-1-2 that the shrapnel cooperates. The strip-shaped clamping part 1-1-1 and the sheet-shaped contact part 1-1-2 are integrally formed, and the sheet-shaped contact part 1-1-2 is arranged on one end of the strip-shaped clamping part 1-1-1 and the metal Shrapnel 1-3 corresponds. In this embodiment, the upper end of the preferred metal elastic piece 1-3 is provided with a bent portion, one side of the bent portion is the bump contact surface 1-3-1, and the other side of the bent portion is the clamping elastic piece contact surface 1-3-2. When the metal shrapnel 1-3 is deformed under the extrusion of the bump 2-1, the bump contact surface 1-3-1 of the metal shrapnel 1-3 is in contact with the bump 2-1, and the clamping shrapnel of the metal shrapnel 1-3 The contact surface 1-3-2 is in contact with the sheet-shaped contact portion 1-1-2 of the thread clamping elastic sheet 1-1.

When the lamp body is actually installed, the wire pin of the double-ended lamp is inserted into the gap of the clamping shrapnel 1-1 of the base 1, and the lamp body limit shrapnel 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, push the upper cover 2 to slide along the base 1. During the sliding process, the upper cover 2 gathers the clamp spring 1-1 so that the clamp spring 1-1 fully contacts the wire pin of the double-ended lamp . The upper cover 2 continues to slide forward, and the bump 2-1 contacts the bump contact surface 1-3-1 of the metal shrapnel 1-3, and pushes the metal shrapnel 1-3 to deform to the sheet shape of the clamping shrapnel 1-1. The contact part 1-1-2 is close, and when the upper cover 2 is installed in place, the contact surface 1-3-2 of the clamping elastic piece of the metal elastic piece 1-3 and the sheet contact part 1-1-2 of the clamping elastic piece 1-1 Contact, the wire needle of the double-ended lamp is electrically connected with the ballast through the clamping shrapnel 1-1 and the metal shrapnel 1-3, and the installation of the lamp body is completed. When it is necessary to replace the double-ended lamp, move the upper cover 2 in the opposite direction, reset the metal shrapnel 1-3, disconnect the contact with the sheet-shaped contact part 1-1-2 of the clamping shrapnel 1-1, and connect the wire needle of the double-ended lamp with the The electrical connection circuit of the ballast is disconnected, so it can work safely. In the installation process of this embodiment, only when the upper cover 2 is installed in place can the wire pins of the double-ended lamp communicate with the ballast, which ensures the personal safety of the staff during the operation and improves the safety performance of the product.
