[0004] The purpose of the utility model is to provide a side protection type lead frame.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A side protection type lead frame includes a frame. Transverse grooves are formed in both the left and right end walls of the frame, and vertical grooves are formed in both the front and rear end walls of the frame. Slide bars are installed on the end walls of the frame near the transverse grooves and vertical grooves. Slide rubber seats are installed inside the transverse grooves and vertical grooves. Through openings are formed in the side end walls of the slide rubber seats, inner seats are installed inside the slide rubber seats, slide openings are formed in the middle of the inner seats, inner grooves are formed in the side end walls of the inner seats, screws are inserted through the side end walls of the inner seats near the inner grooves, and threaded holes are formed through the four corner end walls of the inner seat frame.
[0007] Preferably, two transverse grooves and two vertical grooves are provided.
[0008] Preferably, the transverse grooves and the vertical grooves are symmetrically distributed about the center of the frame.
[0009] Preferably, four slide bars are provided, and the slide bars are fixedly connected to the frame.
[0010] Preferably, the slide rubber seats and the inner seats are adhesively connected.
[0011] Preferably, the inner seat forms a sliding structure with the slide bar through the slide opening, and the inner seat and the screw are threadedly connected.
[0012] The utility model has at least the following beneficial effects:
[0013] 1. The sliding rubber seat is arranged through the horizontal groove and the vertical groove, and the sliding bar is used for sliding connection with the inner seat. During use, the frame is sleeved with a screw piece through the threaded hole for positioning and assembly, which facilitates the assembly of the frame in the electrical appliance housing.
[0014] 2. The sliding rubber seat made of rubber material makes the side end of the inner seat have buffering performance. The sliding port is movable with the sliding bar for sliding displacement of the inner seat to change the position of the inner seat, making the inner seat more flexible during use. Then, the screw is tightened to lock and limit the inner seat after adjusting its position, and the sliding rubber seat is used to protect the side end of the frame to prevent the end wall of the frame from being knocked and damaged.
