Description

Technical Field

[0001] This utility model relates to the field of electrical connector manufacturing technology, and in particular to a terminal in which a spring element is fixed on a conductor. Background Technology

[0002] Traditionally, wire connections are made using terminal blocks, which can be either soldered or screwed. Soldering involves welding the lead-out wire and internal wire to the terminal block separately. While this method provides a strong and reliable connection, it requires soldering equipment for removal or wire replacement, making the process complex, inefficient, and unsuitable for on-site assembly and disassembly. Screw-fixed connections involve wrapping the ends of the lead-out wire and internal wire around a screw and tightening it. This method is also inconvenient and inefficient.

[0003] Chinese Patent Publication (Announcement) No.: CN105680189A, Patent Title: A Direct Insertion Connector and Terminal Block, which discloses the following technical solution: "

[0010] A direct insertion connector, comprising:

[0011] a groove for inserting a wire, wherein an elastic clamping component is provided in the groove;

[0012] the elastic clamping component includes a fixed end and a free end;

[0013] the fixed end of the elastic clamping component is fixedly connected to one side wall of the groove, for controlling the free end to extend and retract with the fixed end as a fixed point, and causing the free end of the elastic clamping component to switch between an extended state and a compressed state;

[0014] when the free end of the elastic clamping component is subjected to pressure, it is in a compressed state, and the wire is clamped between the free end and the other side wall of the groove;

[0015] when the pressure on the free end of the elastic clamping component disappears, it is in an extended state," achieving "

[0016] ..." This technical solution uses an elastic clamping component installed inside the tank to clamp the wires inserted into the tank, which not only saves time and is easy to operate, but also makes the connection reliable and less prone to falling off.

[0004] However, in actual use, the fixed end 201 of the elastic clamping member 200 of this structure is fixedly connected to one side wall of the groove 100 (i.e., the first side wall 101 shown in the figure), from the attached... Figure 1 As can be seen, its fixing method is unstable. Therefore, there is still room for further improvement. Utility Model Content

[0005] The purpose of this invention is to provide a terminal for fixing a spring element to a conductor, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical measures: a terminal with a spring element fixed on a conductor, comprising a conductive plug, characterized in that: the conductive plug is crimped and fixed by a crimping portion of the conductor, a hollow main cavity extends integrally from the rear of the crimping portion, a gripping portion extends integrally from the main cavity, a recess is provided on the gripping portion, a spring element is installed inside the main cavity, the spring element includes a bending portion that generates elastic deformation force, an elastic arm extends from one end of the bending portion, a fixing arm extends from the other end of the bending portion, and a through hole is provided on the fixing arm to accommodate the recess; the opening width of the spring element is A, the opening width of the main cavity is B, wherein A>B.

[0007] Compared with existing technologies, the advantages of this invention are as follows: This novel structure, by inserting a spring element into the conductor to form a fixed connection, ensures high conductivity and good vibration resistance when the wire is inserted, as the spring element tightly presses against the conductor. When the wire needs to be removed, pressing the spring element with a pin unlocks the wire, facilitating operation, installation, and maintenance. It can connect wires of different diameters to meet various application requirements.

[0008] As an improvement of this utility model, a toothed groove is provided inside the main cavity. The purpose of this design is twofold: when no wire is inserted, the elastic arm of the spring element can abut against the recessed toothed edge, sharing the force with the fixed arm and preventing it from falling out. When a wire is inserted, the elastic arm, under the action of elastic force, presses against the toothed groove; due to the reduced force-bearing area, the pressure can be increased.

[0009] As an improvement of this utility model, the second elastic arm is provided with a guide bevel for easy insertion. The purpose of this design is that the guide bevel can smoothly pass through the obstruction of the recess of the fixed arm, facilitating assembly.

[0010] As an improvement to this utility model, the recessed part is square in shape, and the through hole is also square. The purpose of this design is to ensure that the square hole and the square recessed part match each other, making it less likely to fall out and resulting in a more stable connection.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example 1

[0024] Please refer to Figure 1-9 .in Figure 2 and Figure 3 , Figure 4 and Figure 5 , Figure 6 and Figure 7 These are images of the same component from different perspectives (for a more intuitive understanding).

[0025] This embodiment provides a terminal for fixing a spring element to a conductor, which consists of a conductive plug 1, a conductor 2, and a spring element 7. The conductive plug 1 can be either a male conductive plug or a female conductive plug.

[0026] In the embodiments of this utility model application, please refer to Figure 6 and Figure 7 The conductive plug 1 is crimped and fixed by the crimping part 3 of the conductor 2. A hollow main cavity 4 extends integrally from the rear of the crimping part 3. A gripping part 5 extends integrally from the main cavity 4, and a recessed part 6 is provided on the gripping part 5. The main cavity 4 is used to install the spring element 7.

[0027] In the embodiments of this utility model application, please refer to Figure 4 and Figure 5 The spring element 7 includes a bent portion 8 that generates elastic deformation force. One end of the bent portion 8 extends into an elastic arm 9, and the other end extends into a fixed arm 10. The fixed arm 10 is provided with a through hole for accommodating the recessed portion 6.

[0028] In the embodiments of this utility model application, please refer to Figure 4 and Figure 8 The opening width of the spring element 7 is A, and the opening width of the main cavity 4 is B, wherein A > B. This structure allows the spring element 7 to be firmly supported within the conductor 2.

[0029] In the embodiments of this utility model application, please refer to Figure 7 , Figure 8 and Figure 9 The main cavity 4 is provided with a toothed groove 11. The toothed groove 11 has two functions: when no wire is inserted, the elastic arm 9 of the spring element 7 can abut against the recessed toothed edge, and together with the fixed arm 10, they are subjected to force in balance and will not fall out. When a wire is inserted, the elastic arm 9 is pressed against the toothed groove 11 under the action of elastic force. Since the force-bearing area is reduced, the pressure can be increased.

[0030] In the embodiments of this utility model application, please refer to Figure 4 The elastic arm 9 is provided with a guide bevel 12 for easy insertion. The guide bevel 12 can smoothly pass through the obstruction of the recess 6 of the gripping part 5, facilitating assembly.

[0031] Furthermore, the recessed portion 6 is square in shape, and the through hole is a square hole 13. The square hole 13 matches the square recessed portion 6, making it less likely to fall out and ensuring a more stable connection.

[0032] This embodiment provides a terminal for fixing a spring element to a conductor. They are connected as follows: the square hole 13 of the fixing arm 10 of the spring element 7 and the recessed part 6 of the gripping part 5 of the conductor 2 are engaged with each other; the elastic arm 9 of the spring element 7 presses against the toothed edge of the toothed groove 11 to achieve a fixed connection of the spring element 7 in the conductor 2.

[0033] This embodiment provides a terminal where a spring element is fixed to a conductor. During normal use, the wire 14 pushes open the elastic arm 9 of the spring element 7 and is inserted to the bottom. After insertion, the wire 14 is automatically pressed and connected by the elastic arm 9 of the spring element 7. When the wire needs to be removed, the pin is used to hold the elastic arm 9 in place, and the wire can be easily removed. The operation is convenient.

[0034] The beneficial effects of this utility model are as follows: This novel structure, by inserting the spring element 7 into the conductor 2 to form a fixed structure, ensures that when the wire 14 is inserted, it is tightly connected to the conductor 2 under the pressure of the spring element 7, resulting in high conductivity reliability and good vibration resistance. When the wire 14 needs to be pulled out, the pin is used to press the spring element 7, and the wire is unlocked, making operation and installation convenient and maintenance easy. It can connect wires of different diameters to meet different application needs.
