Description

Technical Field

[0001] The utility model belongs to the technical field of lighting fixtures, and in particular relates to a power supply system. Background Art

[0002] Existing power supply systems, such as the Chinese utility model patent "A plug assembly and a shelf lamp with the plug assembly" with application number CN202222623101.7 and authorization announcement number CN218295662U, have a plug assembly including a shell and a conductive part. The bottom wall of the shell is provided with a first through hole and a second through hole, and the arrangement direction of the first and second through holes is recorded as the first direction; the conductive part is arranged in the shell and has a first conductive part and a second conductive part. The first conductive part is inserted into the first through hole, and the bottom structure of the first conductive part is located below the bottom wall of the shell. The second conductive part is inserted into the second through hole, and the bottom structure of the second conductive part is located below the bottom wall of the shell; at the same time, at least one of the first conductive part and the second conductive part is arranged to be deformed under the action of external force along the first direction and extend upward into the corresponding through hole. A shelf lamp with a plug assembly includes a lamp holder with a hollow interior, a lamp strip placed horizontally in the lamp holder and extending along a first direction, the plug assembly is inserted into the lamp holder along the direction from the first conductive part to the second conductive part of the conductive member, and is located above the lamp strip, and the bottom structure of at least one of the first conductive part and the second conductive part of the conductive member is in contact with the conductive part of the lamp strip.

[0003] The existing plug assembly equipped with a conductive member is convenient for drawing power from the lamp body, but it also has the following defects:

[0004] 1. Although the conductive member is designed with a first conductive part and a second conductive part for contacting the conductive part of the light strip, there are cases where only the first conductive part or only the second conductive part contacts the conductive part of the light strip during use. In this case, the advantages of the first and second conductive parts are not brought into play. The current at the contact point between the conductive member and the conductive part of the light strip is high, and the temperature rise is high, which affects the service life of the product.

[0005] 2. In the prior art, the power supply wires are usually welded to the conductive parts by soldering, which is inconvenient to operate. Utility Model Content

[0006] The technical problem to be solved by the present invention is to provide a power supply system in view of the current status of the existing technology, so as to facilitate power supply and reduce temperature rise at the same time.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a power supply system, including:

[0008] A power plug having a cavity inside;

[0009] The lamp holder is hollow inside, and one side of the lamp holder has a socket for inserting the power plug, and the socket is oriented to the left;

[0010] A lamp body capable of emitting light is disposed in the lamp holder;

[0011] It is characterized by also including:

[0012] A conductive part capable of conducting electricity is arranged in the cavity and can be electrically connected to the power supply wire. The conductive part has a left conductive part and a right conductive part arranged on the left and the right. The left conductive part and the right conductive part both extend outward relative to the cavity and are located outside the cavity, and the outward extension distance of the left conductive part is greater than the outward extension distance of the right conductive part. The left conductive part and the right conductive part are both elastic structures. When the power plug is inserted from left to right into the socket, the left conductive part and the right conductive part are compressed inwardly, so that the left conductive part and the right conductive part generate an elastic restoring force and abut against the conductive parts of the lamp body.

[0013] When drawing electricity, just insert the power plug into the socket of the lamp holder from left to right, which is convenient for operation. And because the outward extension distance of the left conductive part on the conductive part is greater than the outward extension distance of the right conductive part, when the power plug is inserted into the socket of the lamp holder from left to right, the right conductive part first produces a smaller elastic deformation and abuts against the conductive part of the lamp body, and then the left conductive part produces a larger elastic deformation and abuts against the conductive part of the lamp body. In this way, both the left and right conductive parts abut against the conductive parts of the lamp body, which improves the stability of contact conduction, reduces the current at the contact point, and thus reduces the heat generation at the contact point, so that the temperature rise of the power supply system is slower when working, thereby improving the safety and service life of the product.

[0014] The conductive member of the present invention can be electrically connected to the end of the power supply wire by welding. To avoid welding and improve operational convenience, the conductive member preferably also has a card interface provided corresponding to the open opening on the left wall of the cavity. The size of the card interface is arranged to match the size of the end of the power supply wire, so that the end of the power supply wire can be inserted into the card interface through the open opening and contact the inner wall surface of the card interface. In this way, the electrical connection between the power supply wire and the conductive member can be achieved by inserting the end of the power supply wire into the card interface through the open opening, which facilitates operation.

[0015] Preferably, the conductive part has a first spring sheet extending left and right, the first spring sheet is arranged in the cavity, and the left end of the first spring sheet is bent to form the above-mentioned card interface that passes through the left and right sides, and the right end of the first spring sheet has the above-mentioned left conductive part and right conductive part.

[0016] Furthermore, the left end portion of the first elastic piece has a central portion and side portions on both sides of the central portion in the transverse direction. The central portion is arc-shaped and together with the two side portions forms the above-mentioned card interface.

[0017] Furthermore, the two side portions are arranged at an acute angle, resulting in a V-shaped cross-section at the left end of the first spring. The ends of the V-shaped opening abut against the inner wall of the cavity under the action of the power supply wire inserted into the card interface. The force exerted by the inner wall of the cavity on the ends of the V-shaped opening enables the card interface to further clamp the end of the power supply wire.

[0018] Preferably, the conductive part also has a second spring piece extending downward and obliquely to the left from the right end portion of the first spring piece, a third spring piece extending upward and obliquely to the left from the lower end of the second spring piece, a fourth spring piece extending downward and obliquely to the left from the upper end of the third spring piece, and a fifth spring piece extending upward from the lower end of the fourth spring piece. The second spring piece and the third spring piece constitute the above-mentioned right conductive part, and the fourth spring piece and the fifth spring piece constitute the above-mentioned left conductive part. When the power plug is inserted into the socket, the intersection of the second spring piece and the third spring piece and the intersection of the fourth spring piece and the fifth spring piece both abut against the conductive component of the lamp body. When the power plug is detached from the socket, the intersection of the second spring piece and the third spring piece is located above the intersection of the fourth spring piece and the fifth spring piece.

[0019] When the power plug is inserted into the socket of the lamp holder from left to right, the structure of the left and right conductive parts of the utility model is conducive to elastic deformation along with the insertion action of the power plug until both left and right conductive parts abut against the conductive parts of the lamp body.

[0020] Preferably, a tongue piece is provided at the middle portion of the first elastic piece between the left and right ends, the right end of the tongue piece in the longitudinal direction being integrally connected to the first elastic piece, and the left end being a free end extending upwardly and obliquely. The top wall of the cavity is provided with an insertion hole for inserting the tongue piece. The cooperation between the insertion hole and the tongue piece can achieve position limiting of the first elastic piece.

[0021] In the above schemes, preferably, the lamp holder is in the shape of a long strip extending left and right, the socket is located at the left end of the lamp holder, and the socket is closed by inserting a power plug into the socket.

[0022] Furthermore, there are two cavities in the power plug, which are arranged side by side and spaced apart, and the above-mentioned conductive member is provided in each cavity.

[0023] Compared with the prior art, the advantages of the present invention are that when drawing electricity, the power plug can be inserted into the socket of the lamp holder from left to right, which is convenient for operation. Moreover, since the outward extension distance of the left conductive part on the conductive part is greater than the outward extension distance of the right conductive part, when the power plug is inserted into the socket of the lamp holder from left to right, the right conductive part first produces a smaller elastic deformation and abuts against the conductive part of the lamp body, and then the left conductive part produces a larger elastic deformation and abuts against the conductive part of the lamp body. In this way, both the left and right conductive parts abut against the conductive parts of the lamp body, thereby improving the stability of contact conduction, reducing the current at the contact point, thereby reducing the heat generation at the contact point, and making the temperature rise of the power supply system slower when working, thereby improving the safety and service life of the product.

[0031] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 7 FIG. 1 shows a preferred embodiment of a power supply system of the present invention. The power supply system includes a power supply plug 1 , a lamp holder 2 , a lamp body 3 and a conductive member 4 .

[0033] The lamp holder 2 is in the shape of a long strip extending leftward and rightward and having a hollow interior. A socket 20 is provided at the left end of the lamp holder 2 .

[0034] The lamp body 3 is a long strip of luminous LED light, which is arranged in the lamp holder 2 along the longitudinal direction.

[0035] like Figure 2 、 4As shown, the power plug 1 is inserted into the socket 20 of the lamp holder 2 from left to right to close the socket 20. The power plug 1 has a cavity 10 inside, with an opening 11 on the left side wall and a socket 12 on the top wall.

[0036] The conductive member 4 is disposed within the cavity 10. The conductive member 4 has a card interface 40 corresponding to the opening 11 on the left side wall of the cavity 10. The size of the card interface 40 is arranged to match the size of the end of the power supply wire 5, so that the end of the power supply wire 5 can be inserted into the card interface 40 through the opening 11 and contact the inner wall surface of the card interface 40, thereby electrically connecting the end of the power supply wire 5 to the conductive member 4. For details, please refer to Figure 2 、 3 , 4, 5, 7. The conductive member 4 further includes a left conductive portion 4a and a right conductive portion 4b, which are arranged on the left and right sides respectively. The left conductive portion 4a and the right conductive portion 4b both extend outward relative to the cavity 10 and are located outside the cavity 10. The outward extension distance of the left conductive portion 4a is greater than the outward extension distance of the right conductive portion 4b. In addition, the left conductive portion 4a and the right conductive portion 4b both have elastic structures. When the power plug 1 is inserted from left to right into the socket 20, the left conductive portion 4a and the right conductive portion 4b are compressed inwardly, so that the left conductive portion 4a and the right conductive portion 4b generate elastic restoring force and abut against the conductive component of the lamp body 3.

[0037] Specifically, the conductive part 4 has a first spring piece 41 extending left and right, and the first spring piece 41 is arranged in the cavity 10. The left end of the first spring piece 41 has a central part 411 and side parts 412 on both sides of the central part 411 in the width direction. The central part 411 is arc-shaped, and together with the two side parts 412, it forms the above-mentioned card interface 40 that passes through the left and right, and the two side parts 412 are arranged at an acute angle, so that the cross-section of the left end of the first spring piece 41 is an inverted V shape, and the two ends of the inverted V-shaped opening abut against the inner wall surface of the cavity 10 under the action of the power supply wire 5 inserted into the card interface 40. At the same time, the conductive member 4 also has a second elastic piece 42 extending downward and obliquely to the left from the right end portion of the first elastic piece 41, a third elastic piece 43 extending upward and obliquely to the left from the lower end of the second elastic piece 42, a fourth elastic piece 44 extending downward and obliquely to the left from the upper end of the third elastic piece 43, and a fifth elastic piece 45 extending upward from the lower end of the fourth elastic piece 44. The second elastic piece 42 and the third elastic piece 43 constitute the above-mentioned right conductive part 4b, and the fourth elastic piece 44 and the fifth elastic piece 45 constitute the above-mentioned left conductive part 4a. When the power plug 1 is inserted into the socket 20, the intersection of the second elastic piece 42 and the third elastic piece 43 and the intersection of the fourth elastic piece 44 and the fifth elastic piece 45 all abut against the conductive component of the lamp body 3. When the power plug 1 is disconnected from the socket 20, the intersection of the second elastic piece 42 and the third elastic piece 43 is located above the intersection of the fourth elastic piece 44 and the fifth elastic piece 45.

[0038] In addition, a tongue 413 is provided in the middle part of the first elastic piece 41 between the left end and the right end. The right end of the tongue 413 in the length direction is connected to the first elastic piece 41 as a whole, and the left end is a free end extending upward at an angle. The tongue 413 is inserted upward into the socket 12 on the top wall of the cavity 10.

[0039] Meanwhile, in this embodiment, there are two cavities 10 in the power plug 1 , which are arranged side by side and spaced apart. The above-mentioned conductive member 4 is provided in each cavity 10 .

[0040] During assembly, the conductive member 4 can be inserted upward into the cavity 10 through the opening in the bottom wall of the cavity 10. Because the left end of the first elastic member 41 has an inverted V-shaped cross-section, the portion of the cavity 10 corresponding to the left end of the first elastic member 41 has a larger upper space and a smaller lower space. As the conductive member 4 is inserted into the cavity, the inverted V-shaped opening at the left end of the first elastic member 41 first closes and then opens, thereby stably constraining the conductive member 4 within the cavity 10. After the conductive member 4 is assembled into the power plug 1, the power plug is inserted from left to right into the socket 20 of the lamp holder 2. During insertion, the right conductive portion 4b first undergoes a smaller elastic deformation, abutting against the conductive components of the lamp body 3. Then, the left conductive portion 4a undergoes a larger elastic deformation, abutting against the conductive components of the lamp body 3. This ensures that both the left and right conductive portions abut against the conductive components of the lamp body 3, improving contact stability and reducing current at the contact point, thereby reducing heat generation at the contact point. This results in a slower temperature rise during operation of the power supply system, thereby improving product safety and service life.

[0041] When power is needed, the end of the power supply wire 5 is inserted into the card interface 40 through the open port 11 on the power plug 1, which is convenient for operation.

However, these terms are used herein for convenience of description only and are based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different orientations, these directional terms are intended for illustrative purposes only and should not be construed as limiting. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
