Description

Technical field:

[0001] The utility model relates to the technical field of lamp holder products, in particular to an improved switchless lamp holder with stable connection and simple structure. Background technology:

[0002] In recent years, the world has vigorously advocated energy conservation and emission reduction for the sake of earth resources and the earth's environment. In particular, in terms of lighting, energy-saving fluorescent bulbs and LED bulbs have been developed and strongly advocated to replace traditional power-consuming and inefficient black filament bulbs. This is because the reason why black filament bulbs consume power is that most of their energy is consumed in heating, and only a small part of the energy is used for light emission, so their light emission efficiency is low. In addition, the wiring method of black filament bulbs generally uses screws to wrap the wires and then tighten them. The wiring speed is slow, the efficiency is low, and the reliability needs to be improved.

[0003] Later, lamp holders with plug-in wiring methods appeared on the market to replace the traditional wiring method of wrapping wires with screws. The plug-in wiring method greatly accelerated the wiring speed of the lamp holder and saved a lot of time.

[0004] At present, there are many plug-in lamp holders on the market, such as: Chinese utility model patent application with patent announcement number CN203014124U discloses a plug-in lamp holder, which includes: a lower base, a concave cavity is provided between the lower base and the upper base, a switch zipper is provided in the concave cavity between the lower base and the upper base, two wiring cavities are provided in the upper base, a wire hole connected to the surface of the upper base is provided at the upper end of the wiring cavity, a negative electrode clamp and a positive electrode clamp are respectively installed in the two wiring cavities, the negative electrode clamp and the positive electrode clamp are provided with vertical bars that contact the inner wall of the wiring cavity, and the vertical bars of the negative electrode clamp and the positive electrode clamp are provided with outward barbs. The plug-in lamp holder has a simple structure, quick and fast assembly, easy use, and is safe and reliable.

[0005] However, the existing plug-in type lamp holder still has the following shortcomings:

[0006] In this technical solution, by arranging a switch zipper in the concave cavity between the lower substrate and the upper substrate, and opening a wire hole connected to the surface of the upper substrate at the upper end of the wiring cavity, the lamp holder can be quickly assembled, which speeds up the wiring installation. However, it is not provided with a hook that can limit the wire, nor is it provided with other gear structures. When the lamp holder is in use, the wire is often pulled by external force. If the wire is not limited, the tension on the wire will directly act on the wire hole, causing the connected wire core to easily slip out of the wire hole, thereby disconnecting the connection and affecting normal use.

[0007] In view of this, the inventor proposes the following technical solution. Utility model content:

[0008] The purpose of the present utility model is to overcome the deficiencies of the prior art and provide an improved switchless lamp socket.

[0009] To solve the above technical problems, the present utility model adopts the following technical solutions: An improved switchless lamp socket, comprising: an insulating base, on which a connection groove is formed for connecting with the lamp head of the lamp body, and two wire holes are also provided on the insulating base; a first conducting piece, which is arranged in the connection groove and used to form an electrical connection with the lamp head, and one end of the first conducting piece extends downward and closely adheres to the inner wall of the connection groove; a second conducting piece, which is arranged in the connection groove and used to form an electrical connection with the lamp head, and one end of the second conducting piece is bent and extended to the top of the connection groove; an end cover is covered on the insulating base, two hooks for limiting the external power cord are convexly formed on the upper end surface of the insulating base, and correspondingly, two protrusions for preventing the external power cord from disengaging from the two hooks are also convexly formed upward on the upper end surface of the insulating base.

[0010] Furthermore, in the above technical solution, hook parts corresponding to the two protrusions are respectively convexly formed downward on the two hooks.

[0011] Furthermore, in the above technical solution, a first side groove and a second side groove are formed on the inner wall of the connection groove, and the first conducting piece is accommodated in the first side groove; an internal thread section for helically connecting with the lamp head of the lamp body is also convexly formed on the inner wall of the connection groove.

[0012] Furthermore, in the above technical solution, two positioning cavities for accommodating the first and second conducting pieces are formed inside the insulating base, and the two wire holes are communicated with the two positioning cavities. Two wires of the external power cord are inserted into the insulating base through the two wire holes and are respectively fixedly connected to the first and second conducting pieces.

[0013] Furthermore, in the above technical solution, first and second barb pieces are respectively convexly formed on the first and second conducting pieces, and clamping grooves corresponding to the first and second barb pieces are arranged at corresponding positions on the two positioning cavities.

[0014] Furthermore, in the above technical solution, the first conducting piece includes: a first bending section, a first connecting section integrally formed with the first bending section and extending below the wire hole among the two wire holes, and a first contact section integrally formed with the first bending section and extending downward. The wire 7 among the two wires 78 is fixedly connected to the first connecting section.

[0015] Furthermore, in the above technical solution, the second conductive piece includes: a second bending section, a second connecting section integrally formed with the second bending section and extending to below one of the two wire holes, and a second contact section integrally formed with the second bending section and extending to the top of the connecting groove, and one of the two wires 7 is fixedly connected to the first connecting section.

[0016] Furthermore, in the above technical solution, two protrusions protrude upward from the upper end surface of the insulating seat, and two wire holes are formed on the two protrusions for inserting an external power cord; a first avoidance groove and a second avoidance groove are respectively formed on both sides of the end cover for matching with the two protrusions; an external spiral groove is spirally opened on the end cover for spiral connection with the outside.

[0017] Furthermore, in the above technical solution, two undercuts are formed downwardly protruding inside the end cover for being buckled and fixed with the insulating seat, and correspondingly, two snap-in holes for being fixedly snap-in with the two undercuts are respectively opened on the insulating seat.

[0018] Furthermore, in the above technical solution, the insulating seat is formed with an external thread section on the outer wall of the connecting groove, and a locking ring for locking the external lampshade is spirally connected to the external thread section.

[0019] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: in the utility model, by arranging two hooks and two protrusions on the upper end surface of the insulating seat, a clamping position is formed between the two hooks and the two protrusions. When wiring, the external power cord is respectively bypassed by the hooks and connected to the two wire holes. The structure is simple and practical. Not only can it be assembled quickly, the speed of wiring installation is accelerated, but also when the external power cord is pulled, since the external power cord is limited to the clamping position between the two hooks and the two protrusions, the force point of the external power cord tension will mainly fall on the hook, and will not affect the two wire holes, which is equivalent to adding a layer of buffer, which can effectively prevent the wire core of the external power cord from falling out of the two wire holes due to excessive external force. On the basis of ensuring the simplicity of structure, the stability of the lamp holder is greatly enhanced, making the utility model highly competitive in the market. Description of the drawings:

[0028] The present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0029] See Figures 1 to 7 As shown, it is an improved switchless lamp socket. In the first embodiment, it includes: an insulating base 1, on which a connection groove 10 for connecting with the lamp head of the lamp body is formed, and two wire holes 111, 112 are also opened on the insulating base 1; a first conducting piece 3, which is arranged in the connection groove 10 and used for forming an electrical connection with the lamp head, and one end of the first conducting piece 3 extends downward and closely adheres to the inner wall of the connection groove 10; a second conducting piece 4, which is arranged in the connection groove 10 and used for forming an electrical connection with the lamp head, and one end of the second conducting piece 4 is bent and extended to the top of the connection groove 10; one end cover 2 is covered on the insulating base 1, and two hooks 13, 14 for limiting the external power cord are convexly formed on the upper end surface of the insulating base 1. Correspondingly, two protrusions 15, 16 for preventing the external power cord from disengaging from the two hooks 13, 14 are also convexly formed upward on the upper end surface of the insulating base 1.

[0030] In this embodiment, by providing two hooks 13, 14 and two protrusions 15, 16 on the upper end surface of the insulating base 1, a clamping position is formed between the hooks 13, 14 and the protrusions 15, 16. When wiring, the external power cord is respectively wound around the hooks 13, 14 and inserted into the two wire holes 111, 112. The structure is simple and practical, not only enabling rapid assembly and accelerating the wiring and installation speed, but also when the external power cord is pulled, since the external power cord is limited in the clamping position between the two hooks 13, 14 and the two protrusions 15, 16, the stress point of the pulling force of the external power cord will mainly fall on the hooks 13, 14, without affecting the two wire holes 111, 112, which is equivalent to adding a layer of buffering, and can effectively prevent the wire cores of the external power cord from protruding out of the two wire holes 111, 112 due to excessive external force. On the basis of ensuring a simple structure, the use stability of the lamp base is greatly enhanced, making the utility model highly competitive in the market.

[0031] Hook parts 131, 141 corresponding to the protrusions 15, 16 are respectively formed to protrude downward on the two hooks 13, 14. Here, the external power cord is further limited between the two hooks 13, 14 and the protrusions 15, 16.

Here, the internal thread section 103 of the connection groove 10 is formed by an integrally molded plastic method, and the lamp head of the lamp body is helically connected with the lamp base through the internal thread section 103. When the lamp head is helically installed, the outer wall of the lamp head will be in contact with the inner wall of the connection groove 10. The first side groove 101 is provided to prevent the first conducting piece 3 from protruding excessively from the inner wall of the connection groove 10 and affecting the smoothness of the helical connection. At the same time, the first conducting piece 3 can be more stably electrically connected with the lamp head.

[0033] Combined with Figure 4As shown, two positioning cavities 113 and 114 for accommodating the first and second conducting sheets 3 and 4 are formed inside the insulating base 1, and the two wire holes 111 and 112 are in communication with the two positioning cavities 113 and 114. Two wires 7 and 8 of the external power cord are inserted into the insulating base 1 through the two wire holes 111 and 112 and are respectively fixedly connected to the first and second conducting sheets 3 and 4. Here, the upper ends of the first and second conducting sheets 3 and 4 are respectively fixed inside the two positioning cavities 113 and 114. The two wires 7 and 8 of the external power cord respectively pass through the two wire holes 111 and 112 and are inserted into the two positioning cavities 113 and 114, and are respectively connected to the upper ends of the first and second conducting sheets 3 and 4 in a snap-fit manner. And the two wires 7 and 8 respectively bypass the two hooks 13 and 14, such that...

[0034] Combined with Figure 4 As shown, first and second barbs 311 and 411 are respectively formed protruding on the first and second conducting sheets 3 and 4, and corresponding slots 1131 and 1141 are provided at positions corresponding to the first and second barbs 311 and 411 on the two positioning cavities 113 and 114. Here, first and second barbs 311 and 411 are respectively formed protruding on the upper ends of the first and second conducting sheets 3 and 4, so that the first and second conducting sheets 3 and 4 can be respectively stably arranged in the two positioning cavities 113 and 114 without accidental sliding, so as to further enhance the connection stability.

[0035] Combined with Figure 5 and Figure 6 As shown, the first conducting sheet 3 includes: a first bending section 31, a first connecting section 32 integrally formed with the first bending section 31 and extending below the wire hole 111 among the two wire holes 111 and 112, and a first contact section 33 integrally formed with the first bending section 31 and extending downward. The wire 7 among the two wires 7 and 8 is fixedly connected to the first connecting section 32. The second conducting sheet 4 includes: a second bending section 41, a second connecting section 42 integrally formed with the second bending section 41 and extending below the wire hole 112 among the two wire holes 111 and 112, and a second contact section 43 integrally formed with the second bending section 41 and extending to the top of the connection groove 10.

[0036] The shapes of the upper end of the first conductive piece 3 and the upper end of the second conductive piece 4 are the same, and the shapes of the lower end of the first conductive piece 3 and the lower end of the second conductive piece 4 are different because of the different contact positions with the lamp cap.

[0037] Combination Figure 2 and Figure 3 As shown, the upper end surface of the insulating seat 1 has two protrusions 17 protruding upward, and the two protrusions 17, 18 are provided with two wire holes 111, 112 for inserting the external power line; the two sides of the end cover 2 are respectively formed with a first avoidance groove 201 and a second avoidance groove 202 for matching the two protrusions 17, 18; the end cover 2 is spirally provided with an external spiral groove 203 for spiral connection with the outside. Here, the first avoidance groove 201 and the second avoidance groove 202 are respectively engaged with the two wire holes 111, 112, which can prevent foreign objects from falling into the lamp holder and also limit the lamp holder circumferentially.

[0038] Combination Figures 2 to 4 As shown, the end cap 2 is also formed with two undercuts 204 and 205 protruding downwards for buckling and fixing with the insulating seat 1, and correspondingly, the insulating seat 1 is provided with two snap-fitting holes 206 and 207 for fixing and snap-fitting with the two undercuts 204 and 205. Here, when installing the end cap 2, the two undercuts 204 and 205 are aligned with the two snap-fitting holes 206 and 207 respectively, and then the end cap 2 is lightly pressed so that the two undercuts 204 and 205 are snap-fitted with the two snap-fitting holes 206 and 207 respectively. The installation is quick and convenient, and the use is simple and convenient. In addition, the end cap 2 is provided with outlet holes 210 and 220 for the two wires 7 and 8 to pass through the end cap 2. The outlet holes 210 and 220 are used for the two wires 7 and 8 to extend out of the end cap 2 and connect with the outside.

[0039] In the second embodiment of the present utility model, Figure 8 As shown, the insulating seat 1 is formed with an external thread section 104 on the outer wall of the connecting groove 10, and a locking ring 9 for locking the external lampshade is spirally connected to the external thread section 104. Here, the added locking ring 9 can better fix the external lampshade to increase the overall stability. Compared with the first embodiment, this embodiment is different only in the above-mentioned external thread section 104 and the locking ring 9, and the other structures are the same, which will not be repeated here.

[0040] In summary, in the present utility model, by providing two hooks 13, 14 and two protrusions 15, 16 on the upper end surface of the insulating base 1, a clamping position is formed between the two hooks 13, 14 and the two protrusions 15, 16. When wiring, the external power supply wires are respectively wound around the hooks 13, 14 and inserted into the two wire holes 111, 112. The structure is simple and practical, which can not only be assembled quickly, accelerating the wiring and installation speed, but also when the external power supply wire is pulled, since the external power supply wire is limited in the clamping position between the two hooks 13, 14 and the two protrusions 15, 16, the stress point of the pulling force of the external power supply wire will mainly fall on the two hooks 13, 14, without affecting the two wire holes 111, 112. It is equivalent to adding a layer of buffering, which can effectively prevent the wire cores of the external power supply wire from being pulled out of the two wire holes 111, 112 due to excessive external force. On the basis of ensuring the simplicity of the structure, the use stability of the lamp holder is greatly enhanced, making the present utility model highly competitive in the market.
