Description

Technical Field

[0001] The utility model belongs to the technical field of electrical assembly, and particularly relates to an improved wiring terminal and a COB chassis. Background Art

[0002] In the traditional assembly process of COB light sources, wires are first welded to the LED light source wafers, then the LED light source wafers are assembled to the COB insulating chassis, and finally, the COB chassis with the LED light source wafers needs to be fixed to components such as radiators to complete the assembly of the COB light source. In the above COB light source assembly process, since the wires are welded to the LED light source wafers first and then the subsequent assembly work is carried out, the assembly process is complicated, and the way of welding the wires first will affect the glue coating process of the LED light source wafers. In addition, pre-welding the wires to the LED light source wafers also results in a single and fixed wiring method for the COB light source, with poor flexibility.

[0003] To solve the above problems, some COB brackets with plug-and-wire functions have emerged in the prior art. Specifically, a wiring terminal is provided on the COB chassis, and a wire socket is provided on the wiring terminal for the wire to be inserted, so that the wire forms an energized structure with the conductive sheet on the COB chassis or the conductive sheet integrally formed with the wiring terminal, thereby realizing the conductive wiring of the LED light source wafer. Due to the setting of the wiring terminal, the wire can be plugged in and energized after the LED light source wafer, the COB chassis and other components are assembled, simplifying the assembly process and reducing the difficulty. For example, the utility model patent with the authorization announcement number CN219874119U. However, such wiring terminals still have the following defects:

The terms used in the specification of the present utility model herein are only for the purpose of describing specific implementation manners, and are not intended to limit the present utility model.

[0054] Embodiment 1

[0055] Refer to Figures 1-9 , this embodiment discloses an improved wiring terminal, specifically a two-position wiring terminal with a dual plug-in wire function. Among them, the wiring terminal includes an outer shell 1 and two conductive plug-in wire parts 2.

[0056] The housing 1 is provided with two inner cavities 101, and two conductive wiring parts 2 are respectively arranged in the two inner cavities 101. The structures of the two inner cavities 101 of the housing 1 in this embodiment are connected by a connecting part 102. After being assembled with the two conductive wiring parts 2, a two-position wiring terminal with a double-wiring function is formed. In addition, the housing 1 in this embodiment is generally in a "concave" shape, and the concave position 103 at the connecting part 102 can be matched with the protruding block 302 of the chassis 3 to improve the installation accuracy and stability between the chassis 3 and the wiring terminal.

[0057] Further, one end of the wire insertion part in this embodiment is provided with a wire socket 204 for inserting a wire. Plug sockets 1011 are provided at two opposite ends of the housing 1. The wire socket 204 corresponds to one of the plug sockets 1011, and the other plug socket 1011 corresponds to the contact piece 4 on the chassis 3 so that the contact piece 4 can extend into and make conductive contact with the conductive wiring part 2; Squeezing parts 105 for detachably connecting with the chassis 3 are provided on both sides of the housing 1, and the squeezing parts 105 and the installation positions 301 of the chassis 3 are clamped with each other.

[0058] For the convenience of assembly, the squeezing part 105 in this embodiment protrudes on the side surface of the housing 1, and the outer side surface of the squeezing part 105 is inclined. The inclination direction of the outer side surface of the squeezing part 105 in this embodiment is as Figures 1-3 and Figure 6 shown. In this way, when the wiring terminal in this embodiment is inserted into the installation position 301 of the chassis 3, the insertion process is smoother and more convenient, and during the insertion process, it can continuously abut against the side wall of the installation position 301 of the chassis 3 to achieve a fixing effect.

[0059] Further, an arc-shaped clamping position 1051 is provided at the outer side surface of the squeezing part 105. The arc-shaped clamping position 1051 can cooperate with the convex block 3012 on the side surface of the installation position 301 of the chassis 3 to improve the reliability after assembly. In the installed state, the arc-shaped clamping position 1051 matches the convex block 3012 to limit the housing 1 from coming out. The convex block 3012 in this embodiment is also arc-shaped to facilitate the insertion or disassembly with the arc-shaped clamping position 1051. Specifically, during the installation process, the wiring terminal in this embodiment is inserted into the installation position 301 of the chassis 3. During the insertion and installation process, the inclined surfaces of the squeezing parts 105 on both sides of the housing 1 slide over the convex blocks 3012 on both sides of the installation position 301 and keep squeezing and abutting; when the installation is in place, the convex block 3012 is stuck into the arc-shaped clamping position 1051 of the squeezing part 105, and the two abut against each other and restrict each other, which is beneficial to preventing the wiring terminal from coming out and improving the stability. And because the structure of the arc-shaped clamping position 1051 is arc-shaped, during disassembly, the wiring terminal is pulled out with appropriate force, and after the squeezing part 105 on the side surface of the housing 1 is deformed, it can be pulled out. The operation is simple and the structure is reliable.

[0060] The housing 1 of this embodiment can be made of insulating material, preferably plastic, silica gel or other materials with a certain elastic deformation ability. On the one hand, it can achieve the effect of insulating protection, and on the other hand, it is also convenient to cooperate with the installation position 301 of the chassis 3 to realize the detachable function.

[0061] In addition, between the housing 1 of this embodiment and the installation position 301 of the chassis 3 of the COB bracket, an interference fit method can also be used to complete the assembly. For example, the interference fit between the extrusion part 105 of the housing 1 and the installation position 301 can be utilized. The extrusion part 105 is pressed tightly against the side of the installation position 301 through deformation extrusion, so as to realize the stable assembly of the wiring terminal and the chassis 3. Or, the structure of the housing 1 can be further simplified, and the interference fit relationship can be directly formed between the side deformation ability of the housing 1 and the installation position 301, and the stable assembly of the two can also be realized.

[0062] See Figures 1-3 、 Figure 6 、 Figure 9 As shown in, a guiding block 104 is provided on one surface of the housing 1 of this embodiment, and the guiding block 104 protrudes. Correspondingly, a guiding groove 3011 is provided on the chassis 3, and the guiding groove 3011 is open. During installation, the guiding block 104 and the guiding groove 3011 are correspondingly matched. On the one hand, it can improve the accuracy of inserting the wiring terminal during installation, and on the other hand, the guiding block 104 is limited by the end sealing position of the guiding groove 3011, playing the role of limiting the installation in place.

[0063] See Figures 1-2 As shown in, the insertion interface 1011 corresponding to the wire socket 204 in this embodiment can allow the conductive plug-in member 2 to be inserted into the inner cavity 101 of the housing 1, that is, the conductive plug-in member 2 of this embodiment can be assembled into the inner cavity 101 of the housing 1 through this insertion interface 1011. At the same time, an anti-detachment structure for preventing the conductive plug-in member 2 from coming out is provided between the conductive plug-in member 2 and the housing 1.

[0064] See Figures 2-5 As shown in, the anti-detachment structure of this embodiment includes a clamping notch 106 and a clamping piece 201. The clamping notch 106 is arranged on one side of the inner cavity 101 of the housing 1, and the clamping notch 106 communicates with the inner cavity 101 of the housing 1; one end of the clamping piece 201 is connected to the side of the conductive plug-in member 2, and the other end extends obliquely outwards. In the assembled state, the clamping piece 201 or a part of it extends out of the clamping notch 106, and the end corresponds to the sealed part of the housing 1. By setting such an anti-detachment structure, the conductive plug-in member 2 can be effectively prevented from coming out of the housing 1 while realizing the detachable connection between the conductive plug-in member 2 and the housing 1. Specifically, see Figures 4-5, in this embodiment, the card slot piece 201 and the conductive plug-in piece 2 are of an integrally formed structure. Since the card slot piece 201 extends obliquely outwards, such a structure enables the conductive plug-in piece 2 to smoothly pass through the insertion opening 1011 of the outer shell 1 and insert into the inner cavity 101 of the outer shell 1. During the insertion process, the card slot piece 201 contracts inwards through a certain elastic deformation; at the same time, when the card slot piece 201 slides to the card slot notch 106 on the outer shell 1, the card slot piece 201 resets outwards and extends out of the card slot notch 106. At this time, the card slot piece 201 and the card slot notch 106 form an anti-disengagement structure that mutually locks and restricts, effectively preventing the conductive plug-in piece 2 from coming out.

[0065] See Figures 2-3 , further, in the case of adopting the above anti-disengagement structure in this embodiment, in order to facilitate the disassembly of the conductive plug-in piece 2 from the outer shell 1, an anti-disengagement cavity is provided on the side of the card slot notch 106 away from the conductive plug-in piece 2. In the assembled state, the card slot piece 201 or a part of it extends out of the card slot notch 106 and is located in the anti-disengagement cavity; a disassembly opening 107 is provided on one side of the anti-disengagement cavity. Through the anti-disengagement structure of this embodiment, while completing the assembly of the conductive plug-in piece 2 and the outer shell 1, the cooperation between the card slot notch 106 and the card slot piece 201 is also completed to achieve the anti-disengagement effect. When the conductive plug-in piece 2 needs to be disassembled at this time, the card slot piece 201 is pressed inwards through a tool at the disassembly opening 107, so that the card slot piece 201 and the card slot notch 106 no longer restrict each other. At this time, the conductive plug-in piece 2 can be removed from the inner cavity 101 of the outer shell 1.

[0066] The conductive plug-in piece 2 of this embodiment is provided with a cavity 205 for accommodating the electric wire, and a wire clamping piece 202 is provided near the wire socket 204 of the cavity 205; one end of the wire clamping piece 202 is connected to one side of the cavity 205 by an elastic structure 203, and the other end of the wire clamping piece 202 extends to the other side of the cavity 205. Specifically, it can be abutted against or close to the other side of the cavity 205. Its function is to realize the clamping of the electric wire by using the recovery ability or elastic ability after the deformation of the elastic structure 203. The elastic structure 203 of this embodiment can adopt an arc-shaped connection structure, such as Figures 4-5 shown, or other wire clamping structures in the prior art can also be adopted. For details, reference can be made to the prior art. By adopting such a wire clamping piece 202, the structure is simple, which is convenient for the insertion of the electric wire and clamps the electric wire in the cavity 205 of the conductive plug-in piece 2 by using the elastic clamping force of the wire clamping piece 202. In addition, the wire clamping piece 202 and the conductive plug-in piece 2 of this embodiment are integrally formed and are of an integrated structure.

[0067] The conductive plug-in piece 2 of this embodiment is specifically a metal piece and can be manufactured by processing methods such as stamping and bending.

[0068] Furthermore, both ends of the cavity 205 of the conductive plug 2 of this embodiment are connected, that is, one end of the cavity 205 is a wire socket 204 for inserting the wire, and the opening at the other end allows the contact piece 4 on the base frame 3 to extend into, so that the contact piece 4 is in full contact with the conductive plug 2 to achieve conductivity.

[0069] Example 2

[0070] See also Figures 6-9 , this embodiment discloses a COB bracket including the improved terminal block of the above-mentioned embodiment 1. The COB chassis includes a chassis 3, a plurality of contact pieces 4 and a plurality of improved terminal blocks. The improved terminal block in embodiment 1 is a two-position terminal block, so the chassis 3 of the COB bracket of this embodiment is provided with four contact pieces 4 and two improved terminal blocks of embodiment 1. Among them, two mounting positions 301 for assembling with the improved terminal blocks are provided on the chassis 3, and the openings of the mounting positions 301 are located on the outside of the chassis 3. In this embodiment, the openings of the mounting positions 301 are arranged on the outside of the chassis 3, which can make it very convenient to assemble and disassemble the terminal block and the chassis 3, and the terminal block can be inserted or pulled out from the side of the chassis 3 without disassembling other components of the light source.

[0071] Each contact piece 4 of this embodiment is disposed on the base frame 3, and one end of each contact piece 4 is located at the chip position 303 of the LED light source chip, and the other end is located at the installation position 301 assembled with the improved connection terminal.

[0072] After the improved terminal block is assembled at the installation position 301 , the contact piece 4 extends into the inner cavity 101 of the housing 1 and makes conductive contact with the conductive plug-in component 2 , and the extrusion portions 105 at both sides of the housing 1 are pressed against both sides of the installation position 301 .

[0073] Furthermore, the contact piece 4 of this embodiment is limited by the column 304 on the bottom frame 3. The end of the contact piece 4 located at the installation position 301 is bent and tilted; the end of the conductive plug 2 facing the contact piece 4 is provided with an opening. Figures 8-9 As shown, one end of the contact piece 4 located at the installation position 301 is bent upward to form a tilted structure, so that when the terminal block is assembled with the base frame 3, the contact piece 4 can easily pass through the conductive plug-in component 2 of the housing 1 during the insertion process, thereby extending into the cavity 205 of the conductive plug-in component 2 and contacting each other. The bent structure is also conducive to improving the contact stability between the contact piece 4 and the conductive plug-in component 2, maintaining a good conductive effect.

[0074] Example 3

[0075] See also Figures 10-13, the difference between this embodiment and Embodiment 1 mainly lies in that the improved terminal of this embodiment has a single-wire plug-in function, that is, it belongs to a one-position terminal and only cooperates with a wire and a contact piece 4. The housing 1 of this embodiment is provided with an inner cavity 101 and is matched with a conductive plug-in member 2.

[0076] In addition, the elastic structure 203 in this embodiment is also simpler than that in Embodiment 1, and more uses the deformation recovery force of the metal part itself to clamp the wire.

[0077] Embodiment 4

[0078] This embodiment discloses a COB bracket, and the main difference from Embodiment 3 is that the improved terminal of Embodiment 3 is applied.

[0079] See Figures 14-15 , there are two contact pieces 4 on the chassis 3 of this embodiment, which are arranged diagonally. Moreover, in order to better cooperate with the terminal, the contact piece 4 of this embodiment is improved accordingly and is roughly in a "Z" shape so that the contact 4 can extend into the inner cavity 101 of the housing 1 to contact and conduct electricity with the conductive plug-in member 2.

[0080] The above is only the preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Therefore, any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
