Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to an electrical connector that is easy to plug in and unplug. Background Technology

[0002] An electrical connector is a connecting bridge that enables electrical connections and signal transmission between components, electrical assemblies, and electrical systems. It is a fundamental component necessary for the formation of a complete system.

[0003] The electrical connector with patent number CN214477998U is an electrical connector for connecting conductive wires. It achieves electrical connection by inserting the wire into a clamping component, which clamps and fixes the wire to form a contact electrical connection. The clamping component is open-shaped and relies on its own elasticity to form a clamping force to fix the conductive wire. However, since the clamping force formed by its own elasticity is limited, the conductive wire can be accidentally pulled out when pulled forcefully in an unexpected moment, which is not conducive to a stable fixation.

[0004] Therefore, it is necessary to propose an easy-to-plug electrical connector to facilitate the insertion and secure fixation of conductive wires, so as to prevent the conductive wires from being accidentally pulled out when pulled forcefully in an unexpected moment. Utility Model Content

[0005] To address the aforementioned problems, this invention proposes an easy-to-plug electrical connector to facilitate the insertion and secure fixation of conductive wires, preventing them from being accidentally pulled out during sudden forceful pulling.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes an easy-to-plug electrical connector, including a wiring socket and a circuit board. The wiring socket is fixedly connected to the circuit board. The wiring socket includes a protective shell assembly and at least one clamping conductive element. The protective shell assembly is fixedly connected to the circuit board through one end of the clamping conductive element. The clamping conductive element is electrically connected to the circuit board. The other end of the clamping conductive element is provided with a clamping inlet and at least two self-locking clamping ends. The at least two self-locking clamping ends are all housed within the protective shell assembly. The clamping inlet is located between the at least two self-locking clamping ends. The self-locking clamping ends are provided with elastic curling tabs. The at least two elastic curling tabs are aligned along the clamping inlet.

[0008] Furthermore, the elastic coiled sheet is coiled along the clamping inlet in a top-to-bottom direction.

[0009] Furthermore, there are two self-locking clamping ends, which are symmetrically arranged along the clamping inlet.

[0010] Furthermore, the self-locking clamping end is provided in multiple ways, and the multiple self-locking clamping ends are evenly distributed circumferentially along the clamping inlet.

[0011] Furthermore, the clamping conductive element is provided with a retention space, which is located below at least two of the elastic coiled pieces and communicates with the clamping inlet.

[0012] Furthermore, the protective shell assembly includes a bottom shell and a sleeve cover. The bottom shell is fixedly connected to the circuit board through one end of the clamping conductive member, and the other end of the clamping conductive member is housed inside the bottom shell. The sleeve cover covers the bottom shell and shields a portion of the clamping conductive member.

[0013] Furthermore, the bottom shell is provided with a number of receiving cavities equal to the number of the clamping conductive elements. Each receiving cavity corresponds to one of the clamping conductive elements, and at least two self-locking clamping ends of a clamping conductive element are housed in one of the receiving cavities.

[0014] Furthermore, one end of the sleeve cover is provided with an insertion groove, which is aligned with and connected to the clamping inlet.

[0015] Furthermore, one end of the clamping conductive component is provided with a plug-in bracket, which passes through the bottom shell and the circuit board in sequence, and is fixedly connected and electrically connected to the circuit board.

[0016] Furthermore, the bottom shell is provided with a positioning groove, and a portion of the plug-in bracket is housed in the positioning groove.

[0017] The beneficial effects of this utility model are:

[0018] This invention employs a clamping conductive element to clamp and fix the conductive wire during insertion. The clamping conductive element has a clamping inlet and at least two self-locking clamping ends. When the conductive wire is inserted, the end of the conductive wire is aligned with the clamping inlet. After insertion, all the self-locking clamping ends clamp the conductive wire, forming a contact electrical connection. Because the self-locking clamping ends are equipped with elastic coiling tabs, and at least two elastic coiling tabs are aligned along the clamping inlet, all the elastic coiling tabs clamp the conductive wire. The coiling method increases the elastic force, thereby increasing the clamping force on the conductive wire end. This makes it less likely for the conductive wire end to be accidentally pulled out during a sudden pull, which is beneficial for the stable clamping and fixing of the conductive wire end. In summary, this easy-to-plug electrical connector facilitates the insertion and stable fixing of the conductive wire, preventing the conductive wire from being accidentally pulled out during a sudden pull, effectively improving the fixing effect of the electrical connection.

[0027] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0028] Please refer to Figures 1-3 This utility model proposes an easy-to-plug electrical connector, including a wiring socket 2 and a circuit board 1. The wiring socket 2 is fixedly connected to the circuit board 1, and the circuit board 1 is provided with a wiring connector 4, which is electrically connected to the circuit board 1. The function of the wiring connector 4 is the same as that of the wiring socket 2, both being used to plug in and fix conductive wires to achieve electrical connection of the conductive wires. The wiring socket 2 includes a protective shell assembly 21 and at least one clamping conductive element 22. The clamping conductive element 22 is made of metal material, preferably copper alloy, and has elasticity. The protective shell assembly 21 is fixedly connected to the circuit board 1 through one end of the clamping conductive member 22. The clamping conductive member 22 is electrically connected to the circuit board 1. The other end of the clamping conductive member 22 is provided with a clamping inlet 221 and at least two self-locking clamping ends 222. The at least two self-locking clamping ends 222 are all housed in the protective shell assembly 21. The clamping inlet 221 is located between the at least two self-locking clamping ends 222. The self-locking clamping ends 222 are provided with elastic curling pieces 2221. The at least two elastic curling pieces 2221 are aligned along the clamping inlet 221.

[0029] In this embodiment, when the conductive wire is inserted into the wiring socket 2, the conductive wire end 3 is passed through the protective shell assembly 21 and aligned with the clamping inlet 221 for insertion. The conductive wire end 3 is a bare wire end dipped in tin to improve its rigidity. After insertion, all the self-locking clamping ends 222 will abut the conductive wire to form a clamping state, thereby forming a contact electrical connection with the conductive wire end 3. Since the self-locking clamping ends 222 are provided with elastic coiled pieces 2221, and at least two elastic coiled pieces 2221 are aligned along the clamping inlet 221. In this configuration, all the elastic coiling pieces 2221 clamp the conductive wire. The elastic coiling pieces 2221 increase the lateral elastic force by coiling, so that the elastic coiling pieces 2221 contact the conductive wire end 3 in an arc shape, which increases the contact area and thus increases the clamping force on the conductive wire end 3. This makes it less likely for the conductive wire end 3 to be accidentally pulled out when pulled with instantaneous force, which is conducive to the stable clamping and fixing of the conductive wire. If it is necessary to pull out the conductive wire end 3, it is necessary to pull out the conductive wire end 3 slowly with force.

[0030] In summary, this easy-to-plug electrical connector facilitates the insertion and secure fixation of conductive wires, preventing them from being accidentally pulled out during sudden, forceful pulling, thus effectively improving the fixation effect of the electrical connection.

[0031] In this embodiment, to improve the stability of the elastic coiled sheets 2221 and prevent the conductive wire end 3 from being accidentally pulled out when pulled forcefully, the elastic coiled sheets 2221 are coiled from top to bottom along the clamping inlet 221. When the conductive wire end 3 is inserted into the clamping inlet 221, all the elastic coiled sheets 2221 clamp the conductive wire end 3. Since the elastic coiled sheets 2221 are coiled from top to bottom along the clamping inlet 221, if the conductive wire end 3 is accidentally pulled forcefully during the clamping process, the conductive wire end 3 will generate a downward pulling force. This pulling force is transmitted through the conductive... The surface of the wire end 3 acts on the surface of the elastic coil 2221, creating friction. This friction causes the elastic coil 2221 to expand and contract. The expansion and contraction of all the elastic coils 2221 increases the clamping force on the conductive wire end 3, making the conductive wire end 3 more tightly clamped. The conductive wire end 3 cannot be pulled out quickly. If it is necessary to pull out the conductive wire end 3, a pulling force can only be applied slowly from bottom to top to prevent the friction applied by the conductive wire end 3 to the surface of the elastic coil 2221 from triggering the expansion and contraction of the elastic coil 2221.

[0032] In this embodiment, there are two self-locking clamping ends 222, which are symmetrically arranged along the clamping inlet 221. The two self-locking clamping ends 222 can clamp the inserted conductive wire end 3 from the left and right, which can save the manufacturing cost of the clamping conductive part 22 and effectively improve the clamping force.

[0033] In this embodiment, multiple self-locking clamping ends 222 are provided, and the multiple self-locking clamping ends 222 are evenly distributed around the clamping inlet 221. The multiple self-locking clamping ends 222 can clamp and fix the outer periphery of the conductive wire end 3 in a circumferential manner, thereby improving the stability of the clamping. The multiple self-locking clamping ends 222 are mostly used on conductive wire ends 3 with larger diameters.

[0034] In this embodiment, the clamping conductive member 22 is provided with a retention space 223. The retention space 223 is located below at least two elastic coiled pieces 2221 and is connected to the clamping inlet 221. When the conductive wire end 3 is immersed in tin, the conductive wire end 3 can be made into a shape with a large front end and a small rear end, so that when the conductive wire end 3 is inserted from the clamping inlet 221, it is inserted all the way into the retention space 223, and the large end is kept in the retention space 223. At this time, all the elastic coiled pieces 2221 will clamp the small end to increase the clamping force, making it difficult for the conductive wire end 3 to be pulled out.

[0035] In this embodiment, the protective shell assembly 21 includes a bottom shell 211 and a sleeve cover 212. The bottom shell 211 is fixedly connected to the circuit board 1 through one end of the conductive member 22, and the other end of the conductive member 22 is housed inside the bottom shell 211. The sleeve cover 212 covers the bottom shell 211 and shields a portion of the conductive member 22. The bottom shell 211 provides a side protection structure for the conductive member 22. When assembling the wiring socket 2, the bottom shell 211 is first fixedly connected to the circuit board 1 through one end of the conductive member 22, and then the sleeve cover 212 is placed on the bottom shell 211. When inserting the conductive wire 3, the conductive wire 3 is directly inserted through the sleeve cover 212 and into the conductive member 22.

[0036] In this embodiment, the bottom shell 211 has a number of receiving cavities 2111 equal to the number of clamping conductive members 22. Each receiving cavity 2111 corresponds to one clamping conductive member 22. At least two self-locking clamping ends 222 of one clamping conductive member 22 are housed in one receiving cavity 2111. There can be one or more clamping conductive members 22. If there are multiple clamping conductive members 22, the wiring socket 2 can be used to insert other signal lines besides connecting the positive and negative terminals. The receiving cavity 2111 is used to provide a storage space for the clamping conductive members 22 to ensure that the clamping conductive members 22 are stably stored.

[0037] In this embodiment, one end of the sleeve cover 212 is provided with an insertion groove 2121. The insertion groove 2121 is aligned with and connected to the clamping inlet 221. The insertion groove 2121 is used to provide a channel for easy insertion of the conductive wire end 3. At the same time, after the conductive wire end 3 is inserted, the conductive wire can also be bent and placed with the insertion groove 2121 as the bending point, so as to reduce the external space occupied by the conductive wire above the sleeve cover 212.

[0038] In this embodiment, a connector 224 is provided at one end of the clamping conductive component 22. The connector 224 passes through the bottom shell 211 and the circuit board 1 in sequence. The connector 224 is fixedly connected to and electrically connected to the circuit board 1. When fixing the bottom shell 211, the connector 224 passes through the bottom shell 211 and is fixed to the circuit board 1. The part of the connector 224 that passes through the circuit board 1 is soldered to fix it.

[0039] In this embodiment, a positioning groove 2112 is provided inside the bottom shell 211. A portion of the plug-in bracket 224 is housed in the positioning groove 2112. The positioning groove 2112 provides a limiting space for the plug-in bracket 224, so that workers can easily place the plug-in bracket 224 into the positioning groove 2112 and through the bottom of the positioning groove 2112 during assembly, so as to facilitate quick assembly. The plug-in bracket 224 is provided with plug-in pins 2241. The bottom wall of the positioning groove 2112 is provided with a clearance groove 21121. The plug-in pins 2241 pass through the clearance groove 21121 and the circuit board 1 in sequence. The plug-in pins 2241 are fixedly connected to the circuit board 1 and electrically connected. During assembly, the plug-in pins 2241 are aligned with the clearance groove 21121 and inserted, then through the circuit board 1. Finally, the plug-in pins 2241 are soldered to the contacts on the circuit board 1, so that the plug-in pins 2241 are fixedly connected to the circuit board 1 and form an electrical connection.

[0040] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
