Description

Technical Field

[0001] The present invention relates to a wire pressing structure and a 0355 lamp including the wire pressing structure. Background Art

[0002] A wire pressing structure must be provided at the wire outlet of an LED lamp to meet the safety regulations requirements, and the wire outlet must meet certain tensile requirements. To meet the requirements of lamp heat dissipation, metal shells that are easy to dissipate heat are often used for lamps. Currently, most wire pressing structures on LED lamps use the method of screwing and locking to press the wire. Since the wire shell is generally soft, wear will occur at the wire pressing part after it contacts the hard metal, and the power cord will contact the metal parts, posing a safety risk. At the same time, this method requires drilling and tapping on the lamp body, and a process of tightening screws is also required during installation, which is time-consuming and laborious, increasing the material cost and labor cost. Summary of the Invention

[0003] The purpose of the present invention is to solve the above problems and propose a wire pressing solution for lamps that can not only meet the insulation requirements of lamps but also has simple operation and can be automatically produced.

[0004] To achieve the above functions, the technical solution adopted by the present invention is to provide a wire pressing structure for fixing a wire to an electrical housing. The housing has an accommodation space, and at least a part of the wire is located inside the housing. The characteristics are as follows: The wire pressing structure includes a lifting surface provided on the housing and a wire pressing member detachably connected to the housing. The wire pressing member includes a main body part, a pressing part, and a first connecting part. The pressing part includes a free end and a connecting end opposite to the free end. The connecting end is elastically connected to the main body part. The first connecting part is provided on the main body part. A second connecting part is also provided on the housing. The first connecting part and the second connecting part cooperate to fix the wire pressing member to the housing. When the wire pressing member is separated from the housing, the pressing part inclines towards the housing. When the wire pressing member is connected to the housing, the lifting surface pushes the free end of the pressing part to expand away from the main body part to radially abut against the wire.

[0005] Preferably, the number of the pressing parts is two, symmetrically arranged on opposite sides of the main body part.

[0006] Preferably, the wire pressing structure further includes a first stop part. The wire and the first stop part are relatively arranged on both sides of the lifting surface, and the free ends of the two pressing parts respectively abut against the wire and the first stop part.

[0007] Preferably, the wire pressing structure further includes a second stop portion, which is disposed close to the wire and / or the first stop portion. A gap is formed between the second stop portion and the lifting surface. When the pressing portion is unfolded, the free end extends into the space between the second stop portion and the lifting surface.

[0008] Preferably, the free end is provided with a serrated structure.

[0009] Preferably, the first connecting portion and the second connecting portion are connected by snap fit.

[0010] Preferably, the first connecting portion is a claw extending from the main body portion towards the housing direction, a groove is formed on the lifting surface, and the second connecting portion is a clamping groove provided on the inner wall of the groove.

[0011] Preferably, the number of the claws is two and they are oppositely arranged. The line connecting the two claws and the line connecting the two free ends are perpendicular to each other.

[0012] Preferably, the wire pressing member is made of an insulating material.

[0013] The present invention further provides a lamp, including a housing and a wire at least partially disposed in the housing, characterized in that: the lamp further includes the wire pressing structure as described above for fixing the wire to the housing.

[0014] Preferably, the housing includes a wire passing hole, the wire passes through the wire passing hole, the lifting surface and the second connecting portion are disposed on the outer surface of the housing, the installation position of the wire pressing member is adjacent to the wire passing hole, and the wire pressing member is connected to the housing from the outside of the housing.

[0015] The wire pressing structure of the present invention uses a wire pressing member made of an insulating material. The installation of the wire pressing structure can be achieved only by one pressing action, which not only meets the insulation requirements but also reduces the labor cost. The structure of the wire pressing member is small and can be entirely formed by mold, without post-processing, and the part cost is low. At the same time, the installation process of this structure is simple, and automatic production can be realized, which is conducive to mass production. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following further describes the wire pressing structure and the lamp proposed by the present invention in detail with reference to the accompanying drawings and specific embodiments.

[0022] A preferred embodiment of the present invention is as Figure 1 , Figure 2 , Figure 3 shown. The lamp in this embodiment is a spot lamp, and its main parts include a housing 4. The housing 4 has a receiving space 9. Generally, a light source is arranged in the receiving space 9. In some cases, a driving power supply is also arranged, and in other cases, electronic components such as sensors and controllers can also be arranged. The present application does not limit this. In order to supply power to the electronic components such as the light source in the housing 4, a wire 3 passes through a wire passing hole 41 from outside the housing 4 and penetrates into the housing 4, and at least part of the wire 3 is located inside the housing 4. In order to meet the tensile requirements in safety regulations, this embodiment provides a wire pressing structure including a wire pressing member 1. The wire pressing member 1 is detachably connected to the housing 4. During installation, after the wire pressing member 1 and the structure arranged on the housing 4 are cooperatively fixed, the wire 3 is fixed on the housing 4.

[0023] The structure of the wire pressing member 1 is as Figure 4 , Figure 5 shown, and it includes a main body part 11 and a pressing part 12. The pressing part 12 is in a plate shape and includes a free end 121 and a connecting end 122 arranged oppositely. The connecting end 122 is elastically connected to the main body part 11. When the wire pressing member 1 is not installed on the housing 4, as Figure 1 shown, the pressing part 12 inclines towards the housing 4, and a lifting surface 21 is arranged on the housing 4. When the wire pressing member 1 is connected to the housing 4, as the distance between the main body part 11 and the housing 4 becomes smaller, and the connecting end 122 is elastically connected, the lifting surface 21 pushes the free end 121 of the pressing part 12 to expand in a direction away from the main body part 11. The lifting surface 21 is arranged at a position adjacent to the wire passing hole 41. When the pressing part 12 is lifted to a position flush with the main body part 11, as Figure 2 shown, the free end 121 of the pressing part 12 abuts against the wire 3 and presses the wire 3 from the side (radially) to achieve the wire pressing function. In order to ensure reliable wire pressing, in this embodiment, a serrated structure is further arranged at the free end 121 of the pressing part 12 to further enhance the bonding force with the wire 3 and improve the tensile capacity of the wire 3.

[0024] The wire 3 is prevented from being pulled by the abutment of the wire pressing member 1. The wire pressing member 1 should be prevented from moving away from the wire. Therefore, in this embodiment, a first stop portion 22 is further provided on the housing 4. The first stop portion 22 is disposed on opposite sides of the wire passing hole 41 and the lifting surface 21, and protrudes from the lifting surface 21 in a direction away from the housing 4. In this embodiment, the wire pressing member 1 includes two pressing portions 12, and the two pressing portions 12 are symmetrically disposed on both sides of the main body portion 11. When the wire pressing member is fixedly installed, the free ends 121 of the two pressing portions 12 are respectively in contact with the wire 3 and the first stop portion 22. The first stop portion 22 restricts the pressing portion 1 from moving away from the wire 3, so as to ensure the pressure of the pressing member 1 on the wire 1.

[0025] The force applied by the wire pressing member 1 to the wire 3 is perpendicular to the wire. When the wire 3 is pulled, the pressing portion 12 may move away from the lifting surface 21 following the wire 3. Therefore, a second stop portion 23 is further provided on the housing 4. In this embodiment, the second stop portion 23 is disposed near the wire passing hole 41 and is disposed opposite to the first stop portion 22. In other preferred embodiments, the second stop portion 23 may also be disposed on one side near the first stop portion 22, or may be disposed at both places simultaneously. A gap is formed between the second stop portion 23 and the lifting surface 21. When the pressing portion 12 expands, the portion near the free end 121 extends into the gap between the second stop portion 23 and the lifting surface 21. When the wire 3 is pulled outwards, the second stop portion 23 restricts the pressing portion 12 from moving outwards together with the wire, thereby ensuring reliable wire pressing.

[0026] In order to fix the wire pressing member 1 to the housing 4, a first connecting portion 13 is further provided on the main body portion 11 of the wire pressing member 1, and a second connecting portion 24 which cooperates therewith is also provided on the housing 4. In this embodiment, the first connecting portion 13 is a claw protruding from the main body portion 11 towards the housing 4, and the second connecting portion 24 is a card slot provided on the housing. As Figure 3 shown, a groove 25 is formed on the lifting surface 21, and the card slot serving as the second connecting portion 24 is disposed on the inner side wall of the groove 25. The number of claws is two and they are disposed oppositely. The connection line of the two claws is perpendicular to the connection line of the two free ends 121. The first connecting portion 13 and the second connecting portion 24 are snap-connected, and after the wire pressing member 1 is fixed to the housing 4, the wire 3 is pressed. The snap connection is convenient for installation, and the installation and fixation of the wire pressing member 1 can be achieved only by a pressing action without other tools.

[0027] In other embodiments, the first connecting portion 13 may also be a screw, and the second connecting portion 24 may be a screw hole, and the two are fixedly connected by screw threads. In this case, the pressing portion 12 may be arranged only on one side of the main body portion 11, and the first stop portion 22 may not be required either, and positioning can be directly achieved through the screw.

[0028] To achieve the effect of electrical isolation, the material of the wire pressing member 1 should be an insulating material such as plastic or silicone rubber.

[0029] The above wire pressing structure can be arranged at any position of the lamp according to the wiring requirements. Generally, the wire pressing member 1 is arranged near the wire passing hole 41, while the lifting surface 21 and the second connecting portion 24 are both arranged on the outer side of the housing 4, and the wire pressing member 1 is fixed on the outer side of the housing 4. This assembly is the most convenient. When it is necessary to adjust the exposed length of the wire 3, the wire pressing member 1 can be easily removed, adjusted and then reinstalled.

[0030] In addition to being applicable to the spot lamp provided in this embodiment, the above wire pressing structure can also be used in various other lamps such as ceiling lamps, wall lamps, and ceiling lights. This application does not make any limitations in this regard.

[0031] The above description of the preferred embodiments of the present application is for the purpose of illustration and description, and is not intended to exhaust or limit the present application to the specific forms disclosed. Obviously, many modifications and variations are possible, and these modifications and variations may be obvious to those skilled in the art and should be included within the scope of the present application defined by the appended claims.
