Abstract
Description
Technical Field
[0001] This utility model relates to the field of lamp holder technology, and in particular to a lamp holder with a novel wire fastening device. Background Technology
[0002] Current lamp holders come in various forms, generally consisting of a base, a flexible metal sheet, wire terminals, and a top cover. After the external wire is connected to the wire terminals, frequent movement between the wire and the lamp holder causes tension (including torsional force) between the wire and the terminals. Over time, this can lead to loosening or even detachment of the wire, affecting the lamp holder's wiring performance. Therefore, a novel lamp holder with a wire fastening device is proposed. Utility Model Content
[0003] The purpose of this utility model is to solve the problem in the prior art that tension can occur between wires and wire terminals, leading to loosening or even detachment, and to propose a new type of wire fastening device for lamp holders.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A novel lamp holder for fastening electrical wires includes a base and a top cover. A screw connection mechanism is provided between the base and the top cover. Two metal springs are snapped into the interior of the base, and each of the two metal springs is snapped with an electrical wire terminal. A movable wire clamp is provided on the side wall of the top cover. One end of the top cover is hinged to one end of the movable wire clamp, and the other end of the top cover and the other end of the movable wire clamp are both provided with threaded holes. The two threaded holes are fixedly connected by a first screw.
[0006] Preferably, the base has two locking slots inside, and the metal spring is locked inside the base through the locking slots.
[0007] Preferably, the wire terminal includes a fixing sleeve and a second screw, the second screw being threaded onto the side wall of the fixing sleeve.
[0008] Preferably, one side of the movable clamp is provided with anti-slip texture.
[0009] Preferably, the side wall of the base is provided with connecting threads.
[0010] Compared with the prior art, this utility model provides a lamp holder for a novel wire fastening device, which has the following beneficial effects:
[0011] The lamp holder of this new type of wire fastening device has a top cover, a movable wire clamp, a threaded hole, and a first screw. When the wire is connected to the wire terminal, the movable wire clamp is first rotated open so that the wire passes through between the top cover and the movable wire clamp. Then, the first screw is used to fix the top cover and the movable wire clamp together. This can firmly clamp the wire between the base and the top cover, preventing the wire from loosening or even falling off the wire terminal, thus improving the stability of the wire.
[0012] The parts of this device not described herein are the same as or can be implemented using existing technology. This utility model uses a wire clamping structure in the lamp holder, which allows the wire to be firmly clamped between the base and the top cover, improving the stability of the wire connection.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0021] Reference Figure 1-5 A novel wire fastening device for lamp holders includes a base 1 and a top cover 2. Two metal springs 3 are snapped into the interior of the base 1, and two locking slots 12 are fixed inside the base 1. The metal springs 3 are snapped into the interior of the base 1 via the locking slots 12, allowing for a detachable connection between the metal springs 3 and the base 1. Each of the two metal springs 3 has a wire terminal 4 snapped into it. The wire terminal 4 includes a fixing sleeve 13 and a second screw 14. The second screw 14 is threaded onto the side wall of the fixing sleeve 13. After the conductive part of the wire is inserted into the fixing sleeve 13, the wire is fixedly installed by tightening the second screw 14. The side wall of the top cover 2 has a movable wire clamp 7. One end of the top cover 2 is hinged to one end of the movable wire clamp 7, and the other end of the top cover 2 and the other end of the movable wire clamp 7 both have threaded holes 8. The two threaded holes 8 are fixedly connected by a first screw 9. One side of the movable wire clamp 7 has anti-slip texture 15, which increases the frictional resistance between the top cover 2, the movable wire clamp 7, and the wire, thereby increasing the clamping force.
[0022] When the wire is connected to the wire terminal 4, the movable wire clamp 7 is first rotated open so that the wire passes between the top cover 2 and the movable wire clamp 7. Then, the top cover 2 and the movable wire clamp 7 are fixed by the first screw 9. This can firmly clamp the wire between the base 1 and the top cover 2, preventing the wire from becoming loose or even falling off the wire terminal 4, thus improving the stability of the wire.
[0023] Reference Figure 4 The side wall of the base 1 is provided with a connecting thread 16. The base 1 is connected to the external lampshade by the connecting thread 16, so that the top of the base 1 is covered between the top cover 2.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
