Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and in particular to an electrical connector. Background Technology

[0002] Electrical connectors are widely used in various electronic devices, electrical systems, and linear lighting splicing to achieve pluggable electrical connections between wires / cables and equipment, and between two linear lights. Traditional electrical connectors generally consist of a male plug and a female plug. The male plug has conductive pins, and the female plug has metal sockets. When the male and female plugs are mated, the conductive pins on the male plug are inserted one-to-one into the metal sockets on the female plug, thus achieving an electrical connection. Because the conductive pins and sockets are connected one-to-one, each circuit is a single electrical connection. If one circuit has poor contact, it will cause a problem with the electrical connection. This is especially true in high-power series connections, where poor contact can lead to increased local resistance and severe overheating, easily causing overload and burnout accidents, posing a significant safety hazard. Furthermore, the male and female plugs have different shell structures and are not interchangeable. During manufacturing, the male and female plugs need to be molded separately, resulting in higher production costs. Utility Model Content

[0003] In order to overcome the existing technical defects and solve at least one of the above-mentioned technical problems, the purpose of this utility model is to provide an electrical connector to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: An electrical connector is designed, comprising: a main body shell, wherein at least one dual-path component is disposed on the main body shell, the dual-path component comprising a conductor, a conductive element, and a conductive connector electrically connected to the conductor and the conductive element, the front end of the conductor and the front end of the conductive element being located on the front side of the main body shell, and when two main bodies shells are inserted together, the conductor and conductive element of the dual-path component on one main body shell are inserted and electrically connected to the conductive element and conductive body of the dual-path component on the other main body shell in a one-to-one correspondence, so as to form a dual-path electrical connection between the two dual-path components.

[0005] By adopting the above technical solution, at least one dual-path component is set on the main body shell. Each dual-path component includes a conductor, a conductive element, and a conductive connector that electrically connects the two. When the two main bodies shells are inserted together, the conductor of the dual-path component on one main body shell is connected to the conductive element of the dual-path component on the other main body shell, and the conductive element of the same dual-path component is connected to the conductor of the dual-path component on the other main body shell. This makes it possible for each external connection to form two parallel conductive paths between the two main bodies shells. When one path is temporarily disconnected due to poor contact or other reasons, the other path can still maintain electrical connection independently. This effectively avoids circuit interruption or overload burnout accidents caused by the failure of a single path, significantly reduces safety hazards caused by poor contact, and is particularly suitable for high-power series connection scenarios with good performance.

[0006] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution: In some embodiments, the front side of the main housing is provided with a snap fastener and an insertion hole. The side wall of the insertion hole is provided with a snap-fit ​​groove. When two main housings are inserted together, the snap fastener and snap-fit ​​groove on one main housing correspond one-to-one with the snap-fit ​​groove and snap fastener on the other main housing and engage with each other. The snap fastener and snap-fit ​​groove engage with each other to form a reliable mechanical lock, preventing the connector from loosening due to external forces such as vibration and pulling during use, thus improving the reliability of the connection.

[0007] In some embodiments, the front side of the main body shell is provided with a plug groove and a plug post, the conductor is disposed in the plug groove, and the conductive element is disposed inside the plug post. When the two main bodies shells are inserted into each other, at least one plug groove and plug post on one main body shell are inserted into at least one plug post and plug groove on the other main body shell in a one-to-one correspondence.

[0008] In some embodiments, the conductor has a plug-in portion on its front end periphery to increase the depth of the plug-in groove, and the plug post has a recessed groove on its periphery. When the two main shells are plugged together, at least one plug-in portion and recessed groove on one main shell are plugged into at least one recessed groove and plug-in portion on the other main shell.

[0009] In some embodiments, the height of the insertion portion protruding from the front side of the main body shell is the same as the depth of the recess, and the axial length of the insertion post is the same as the depth of the insertion groove, and is twice the height of the insertion portion protruding from the front side of the main body shell.

[0010] In some embodiments, the conductor is a conductive pin, and the conductive element is a conductive cannula; Alternatively, the conductor may be a rectangular conductive insert, and the conductive element may be an elastic conductive clip.

[0011] In some embodiments, the two main shells are structurally identical and interchangeable, with five dual-channel components provided on each main shell. Since the two main shells are structurally identical and have no male / female distinction, any two main shells can be used interchangeably. Only one mold is needed to complete the injection molding of the main shells during manufacturing, significantly reducing mold-making costs. Furthermore, there is no need to distinguish between male and female connectors on the construction site, which can significantly improve installation efficiency.

[0012] In some embodiments, the upper and lower front parts of the main body shell are respectively provided with the buckle and the insertion hole, and the side wall of each insertion hole is respectively provided with the snap-fit ​​groove.

[0013] In some embodiments, a countersunk groove is provided on the rear side of the main body shell, and the conductive connector is disposed in the countersunk groove. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0016] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional 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.

[0017] In the description of this utility model, unless otherwise explicitly defined, terms such as setting, installing, connecting, and fixing should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0018] Example 1 refer to Figures 1 to 5 As shown, the present invention provides an electrical connector comprising: a main body shell 1, wherein the main body shell 1 is integrally injection molded from an insulating material, such as PC, ABS, PA, PBT and other plastics.

[0019] At least one dual-channel component 2 is fixed on the main body shell 1. The dual-channel component 2 includes a conductor 21, a conductor 22, and a conductor connector 23. One end of the conductor connector 23 is electrically connected to the conductor 21, and the other end is electrically connected to the conductor 22, so that the conductor 21 and the conductor 22 within the same dual-channel component 2 are electrically connected through the conductor connector 23. The front ends of the conductor 21 and the conductor 22 protrude from the front side of the main body shell 1. The dual-channel component 2 is injection molded integrally with the main body shell 1, or is press-fitted into the connection holes on the main body shell 1 through the conductor 21 and the conductor 22.

[0020] When the two main housings 1 are inserted together, the conductors 21 and 22 of the dual-path component 2 on one main housing 1 are connected to the conductors 22 and 21 of the dual-path component 2 on the other main housing 1 in a one-to-one correspondence, thus forming a dual-path electrical connection between the two dual-path components 2. Specifically, the conductors 21 of the dual-path component 2 on one main housing 1 are connected to the conductors 22 of the dual-path component 2 on the other main housing 1 in a one-to-one correspondence; simultaneously, the conductors 21 of the dual-path component 2 on the other main housing 1 are connected to the conductors 22 of the dual-path component 2 on one main housing 1 in a one-to-one correspondence. Thus, a dual-path electrical connection is formed between the two dual-path components 2. When one path is temporarily disconnected due to poor contact or other reasons, the other path can still maintain an independent electrical connection.

[0021] Furthermore, the conductor 21 is a cylindrical conductive pin, and the conductive element 22 is a cylindrical conductive tube. The conductor 21, conductive element 22, and conductive connector 23 are made of copper or copper alloy, preferably copper, meaning the conductor 21 forms a copper pin and the conductive element 22 forms a copper tube. One end of the conductive connector 23 is welded or riveted to the rear end of the conductor 21, and the other end is welded or riveted to the rear end of the conductive element 22, thereby achieving electrical conductivity between the conductor 21 and the conductive element 22 in a dual-path component 2. The conductive connector 23 is used for electrical connection with external wires.

[0022] The two main shells 1 have identical structures and are interchangeable. That is, the electrical connectors do not have male and female plugs, and any two main shells 1 can be directly plugged in and used. Only one mold is needed to complete the injection molding of the main shells 1 during production, which greatly reduces the mold development cost. There is no need to distinguish between male and female plugs on the construction site, which significantly improves the installation efficiency.

[0023] Furthermore, the main body shell 1 is provided with one, two, three, four, five or more dual-path components 2. In this embodiment, five dual-path components 2 are preferably provided on the main body shell 1 to realize the parallel transmission of five signals. Of course, the number of dual-path components 2 provided on the main body shell 1 can be selected according to the number of signals to be transmitted in parallel.

[0024] The front side of the main body shell 1 is provided with one or two buckles 11 and one or two insertion holes 12. In this embodiment, the front side of the main body shell 1 is preferably provided with two buckles 11 and two insertion holes 12. The two buckles 11 are located at the upper and lower parts of the front side of the main body shell 1, and the two insertion holes 12 are located on one side of the two buckles 11. Each insertion hole 12 has a snap-fit ​​groove 13 on its side wall. When the two main body shells 1 are inserted into each other, the buckles 11 and snap-fit ​​grooves 13 on one main body shell 1 correspond one-to-one with the snap-fit ​​grooves 13 and buckles 11 on the other main body shell 1 and snap-fit ​​with each other. Specifically, the two buckles 11 on one main body shell 1 are inserted into the two insertion holes 12 on the other main body shell 1 and snap-fit ​​with the snap-fit ​​grooves 13. The two buckles 11 on the other main body shell 1 are inserted into the two insertion holes 12 on one main body shell 1 and snap-fit ​​with the snap-fit ​​grooves 13. The interlocking action of the buckle 11 and the snap-fit ​​groove 13 effectively prevents the two main shells 1 from coming loose after being inserted, thus improving the stability and reliability of the connection after insertion.

[0025] The front side of the main body shell 1 is provided with insertion slots 14 and insertion posts 15. The number of insertion slots 14 is the same as the number of conductors 21, and multiple conductors 21 are correspondingly disposed in multiple insertion slots 14. The number of insertion posts 15 is the same as the number of conductors 22, and multiple conductors 22 are correspondingly disposed inside multiple insertion posts 15. The front end of the conductor 22 does not protrude from the outside of the insertion post 15. The insertion posts 15 are made of the same material as the main body shell 1 and are integrally formed. When two main body shells 1 are inserted together, the multiple insertion slots 14 and insertion posts 15 on one main body shell 1 are inserted into the multiple insertion posts 15 and insertion slots 14 on the other main body shell 1 in a one-to-one correspondence. Specifically, the multiple insertion posts 15 on one main body shell 1 are inserted into the multiple insertion slots 14 on the other main body shell 1, and the multiple insertion posts 15 on the other main body shell 1 are inserted into the multiple insertion slots 14 on one main body shell 1. This forms a stable insertion structure.

[0026] Furthermore, each conductor 21 has a plug-in portion 16 on its front periphery. The plug-in portion 16 is annular to increase the depth of the plug-in groove 14. The conductor 21 does not protrude outside the plug-in portion 16. The plug-in portion 16 is made of the same material as the main shell 1 and is integrally formed. The plug-in portions 16 are connected to each other, or they can be spaced apart. Each plug post 15 has a recessed groove 17 on its periphery. The recessed grooves 17 are connected to each other, or they can be separate. When two main shells 1 are plugged in, the multiple plug-in portions 16 and recessed grooves 17 on one main shell 1 are plugged in one-to-one with the multiple recessed grooves 17 and plug-in portions 16 on the other main shell 1. Specifically, the multiple plug-in portions 16 on one main shell 1 are inserted into the multiple recessed grooves 17 on the other main shell 1, and the multiple plug-in portions 16 on the other main shell 1 are inserted into the multiple recessed grooves 17 on one main shell 1. After plugging, the end faces of the two main shells 1 on opposite sides are in contact with each other. The fit between the recess 17 and the insertion part 16 further enhances the stability after insertion.

[0027] The height by which the insertion portion 16 protrudes from the front side of the main body shell 1 (i.e., the distance between the front side of the insertion portion 16 and the front side of the main body shell 1) is the same as the depth of the recess 17. The axial length of the insertion post 15 is the same as the depth of the insertion groove 14, and the axial length of the insertion post 15 is twice the height by which the insertion portion 16 protrudes from the front side of the main body shell 1. This significantly increases the insertion area and improves the stability after insertion.

[0028] Multiple countersunk grooves 18 are provided on the rear side of the main shell 1, and multiple conductive connectors 23 are correspondingly arranged in each countersunk groove 18.

[0029] At least one pair of elastic clamping protrusions 231 are provided on the rear side of at least one conductive connector 23. The elastic clamping protrusions 231 are formed by bending the conductive connector 23. Each pair of two elastic clamping protrusions 231 are spaced apart to form a clamping gap for clamping external wires.

[0030] Example 2 This utility model provides another electrical connector, which differs from Embodiment 1 in that the conductor is a rectangular conductive insert and the conductive element is an elastic conductive clip (such as a socket conductive clip). When the two main shells are inserted into each other, the rectangular conductive insert on one main shell is inserted into the insertion gap of the elastic conductive clip on the other main shell, and at the same time, the rectangular conductive insert on the other main shell is inserted into the insertion gap of the elastic conductive clip on the first main shell, forming a cross-insertion dual-path structure.

[0031] Regarding the application areas of the connectors in Embodiments 1 and 2 above, the connector can be used as an accessory on linear lamps. For example, the connector can be installed on the end cap of a linear lamp, and two linear lamps can be spliced ​​and electrically connected by interlocking the connectors between them. Alternatively, the connector can be connected to wires; after connecting the ends of two wires to the connectors respectively, the two wires can be electrically connected by interlocking the two connectors. Furthermore, the connectors connected to the ends of the wires can be interlocked with connectors installed on equipment to achieve electrical connection between the wires and the equipment.

[0032] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
