Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a conductive connection terminal. Background Technology

[0002] Pin-type conductive connectors are widely used in the field of electrical connections, and their conductivity and structural rationality directly affect the operational stability of electrical equipment. Existing pin-type conductive connectors typically consist of a socket, an adapter sleeve, and a conductive element. The assembly process is as follows: first, the conductive element is assembled into the adapter sleeve, and then the entire assembly consisting of the two is assembled into the socket.

[0003] The structural design has obvious shortcomings: the addition of the adapter sleeve not only increases the number of parts, leading to higher material and processing costs, but also increases the overall weight of the terminal, which is not conducive to the lightweight design requirements; when conducting current, it needs to pass through the conductor, the adapter sleeve to the socket, and the extra transmission link will increase the contact resistance, causing conduction loss, which in turn affects the efficiency and stability of current conduction. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a conductive connection terminal.

[0005] The present invention discloses a conductive connection terminal, comprising: a hole sleeve, a conductive element, and a first fixing sleeve. The hole sleeve has an axially oriented insertion hole. The conductive element includes a spring and a plurality of limiting conductive claws spaced apart at one end of the spring. The spring is located inside the insertion hole. The limiting conductive claws have a first contact surface and a second contact surface. The first contact surface abuts against the outer wall surface of the hole sleeve. The first fixing sleeve is sleeved on the plurality of limiting conductive claws and abuts against the second contact surface.

[0006] According to one embodiment of the present invention, the sleeve also has a first bearing step, which is located inside the insertion hole, and the end of the spring away from the limiting guide claw is disposed on the first bearing step.

[0007] According to one embodiment of the present invention, the sleeve further has a second bearing step, the second bearing step is formed on the outer wall surface of the sleeve, and the first fixing sleeve is disposed on the second bearing step.

[0008] According to one embodiment of the present invention, the reed includes a first ring body, a second ring body, and a plurality of elastic bodies. The two ends of the plurality of elastic bodies are respectively connected to the first ring body and the second ring body, and a plurality of limiting and guiding claws are distributed at intervals in the first ring body.

[0009] According to one embodiment of the present invention, a metal layer is further included, which is disposed on the outer wall surface of the sleeve and is located between the first contact surface and the outer wall surface of the sleeve.

[0010] According to one embodiment of this utility model, the reed, the limiting and guiding claw, and the metal layer are made of the same material; the hole sleeve and the metal layer are made of different materials.

[0011] According to one embodiment of the present invention, the sleeve is made of aluminum; the spring, the limiting and guiding claw, and the metal layer are all made of copper.

[0012] According to one embodiment of the present invention, the first fixing sleeve is made of stainless steel.

[0013] According to one embodiment of the present invention, a second fixing sleeve is also included, which is disposed on the inner wall surface of the end of the spring sheet away from the limiting guide claw.

[0014] According to one embodiment of the present invention, the reed and the socket are interference-fitted.

[0015] The beneficial effects of this utility model are that, through the cooperation of multiple limiting and conductive claws with the first fixing sleeve, the spring is not easily disengaged from the socket, thereby fixing the spring. This eliminates the need for the addition of a traditional adapter sleeve, resulting in cost reduction and weight reduction. In addition, current conduction occurs directly between the socket sleeve and the conductive component, reducing the transmission links and effectively reducing conduction losses caused by increased contact resistance, which is beneficial to improving the efficiency and stability of current conduction.

[0018] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model.

[0020] like Figures 1-4 As shown, Figure 1 This is a three-dimensional structural diagram of a conductive connection terminal; Figure 2 This is a split view of the conductive connection terminals; Figure 3 This is a partial cross-sectional schematic diagram of the conductive connection terminal; Figure 4 for Figure 3 Enlarged view of part A in the middle. The conductive connection terminal includes a hole sleeve 1, a conductive element 2, and a first fixing sleeve 3. The conductive element 2 is disposed inside the hole sleeve 1, and the first fixing sleeve 3 is sleeved on the conductive element 2, so that the conductive element 2 is fixed to the hole sleeve 1.

[0021] The sleeve 1 has a socket 11, which is opened along the axial direction of the sleeve 1. A conductive element 2 is disposed in the socket 11, and an external pin is inserted into the socket 11. The conductive element 2 abuts against the outer wall surface of the external pin, and current can be conducted between the external pin, the conductive element 2, and the sleeve 1. Furthermore, the sleeve 1 also has a first bearing step 12, and one end of the conductive element 2 is disposed on the first bearing step 12. The first bearing step 12 restricts the axial movement of the conductive element 2, thereby providing bearing and limiting functions for the conductive element 2. Furthermore, the sleeve 1 also has a second bearing step 13, which is formed on the outer wall surface of the sleeve 1. Specifically, the second bearing step 13 is formed around the outer wall surface of the sleeve 1, and the first fixing sleeve 3 is disposed on the second bearing step 13 to bear and limit the first fixing sleeve 3. In addition, the second bearing step 13 is formed inward toward the insertion hole 11. Therefore, after the first fixing sleeve 3 is inserted, the outer wall surface of the sleeve 1 and the outer wall surface of the first fixing sleeve 3 are joined together and are on the same plane, making the outer wall surface of the entire conductive connection terminal more aesthetically pleasing and without increasing the volume of the conductive connection terminal.

[0022] The conductive element 2 includes a spring 21 and multiple limiting conductive claws 22. The spring 21 is disposed inside the insertion hole 11, and one end of the spring 21 abuts against the first bearing step 12. The multiple limiting conductive claws 22 are spaced apart at the end of the spring 21 away from the first bearing step 12, and the multiple limiting conductive claws 22 are bent and abut against the outer wall surface of the hole sleeve 1. The first fixing sleeve 3 is sleeved on the multiple limiting conductive claws 22. In this embodiment, the spring 21 and the insertion hole 11 are connected by an interference fit, thereby improving the stability of the connection between the two. In practical applications, the reed 21 includes a first ring 211, a second ring 212, and multiple elastic bodies 213. The first ring 211 and the second ring 212 are spaced apart. The second ring 212 abuts against the first bearing step 12. One end of each elastic body 213 is connected to the first ring 211, and the other end of each elastic body 213 is connected to the second ring 212. Multiple limiting and guiding claws 22 are spaced apart on the first ring 211. When the external pin is inserted, the first ring 211, the second ring 212, and the multiple elastic bodies 213 all abut against the outer wall surface of the external pin. After being subjected to the force applied by the external pin, the elastic body 213 expands towards the inner wall surface of the insertion hole 11, and abuts against the inner wall surface of the insertion hole 11. Of course, it is also possible that only the multiple elastic bodies 213 abut against the outer wall surface of the external pin.

[0023] Specifically, the limiting and guiding claw 22 has a first contact surface 221 and a second contact surface 222. The first contact surface 221 abuts against the outer wall surface of the hole sleeve 1, and the inner wall surface of the first fixing sleeve 3 abuts against the second contact surface 222.

[0024] Preferably, the conductive connection terminal further includes a metal layer 4, which is disposed on the outer wall surface of the sleeve 1. The first contact surface 221 of the limiting conductive claw 22 abuts against the metal layer 4. In other words, a metal layer 4 exists between the outer wall surface of the sleeve 1 and the first contact surface 221. In this embodiment, the spring 21, the limiting conductive claw 22, and the metal layer 4 are all made of the same material, while the metal layer 4 and the sleeve 1 are made of different materials. For example, the spring 21, the limiting conductive claw 22, and the metal layer 4 are all made of copper to ensure the efficiency of current conduction; the sleeve 1 is made of aluminum to reduce the overall weight of the conductive connection terminal.

[0025] Specifically, the forming process of the metal layer 4 on the outer wall of the sleeve 1 is as follows: First, the sleeve 1 is placed in a designated position. Then, high-pressure gas is used to transport the pre-prepared powder particles corresponding to the material of the metal layer 4. The powder particles are then mixed with another heated high-pressure gas to form a mixed gas. The mixed gas passes through a Laval tube and is output to the designated position on the surface of the sleeve 1. During the process of the mixed gas passing through the Laval tube, its flow velocity increases from subsonic to supersonic. Finally, it impacts the surface of the sleeve 1. The powder particles, due to their own high-speed kinetic energy, undergo violent deformation at the moment of impact with the surface of the sleeve 1. Through mechanical interlocking and metal bonding, a dense and completely covered metal layer 4 is deposited on the surface of the sleeve 1. The mechanical interlocking and metal bonding between the powder particles and the sleeve 1 can eliminate the gap between the metal layer 4 and the sleeve 1, which is beneficial to solving the electrochemical corrosion problem at the interface between the two. At the same time, it also improves the bonding strength between the metal layer 4 and the sleeve 1.

[0026] Furthermore, the conductive connection terminal also includes a second fixing sleeve 5. The second fixing sleeve 5 is disposed on the inner wall surface of the end of the spring 21 away from the limiting conductive claw 22. It can also be understood that the second fixing sleeve 5 is disposed on the inner wall surface of the second ring 212. The second fixing sleeve 5 allows the second ring 212 to fit tightly against the inner wall surface of the insertion hole 11, thereby improving the fixing effect of the spring 21. At the same time, the second fixing sleeve 5 is also disposed on the first bearing step 12, which supports and limits it.

[0027] In this embodiment, both the first fixing sleeve 3 and the second fixing sleeve 5 are made of stainless steel.

[0028] In summary, by cooperating with the first fixing sleeve 3 through the limiting and conducting claws 22, the spring 21 is not easily disengaged from the socket 11, thereby fixing the spring 21. This eliminates the need for the addition of a traditional adapter sleeve, resulting in cost reduction and weight reduction. In addition, current conduction occurs directly between the socket sleeve 1 and the conducting element 2, reducing the transmission links and effectively reducing conduction losses caused by increased contact resistance, which is beneficial to improving the efficiency and stability of current conduction.

[0029] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
