Description

Technical Field

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

[0002] In electronic devices, electrical systems, and other scenarios requiring current transmission, the connection terminals need to be precisely connected to the adapter to form a circuit path, and are widely used in communications, automotive electronics, industrial control and other fields.

[0003] In existing technologies, cables are typically directly soldered to the connector terminals: after removing the cable insulation to expose the conductor, it is fixed by soldering. This method is widely used because of its mature technology, stable connection, and ability to ensure stable transmission.

[0004] However, the welded structure has significant drawbacks: during later maintenance and replacement, the connecting terminals must first be removed from the base, and then the cable and terminals must be separated by heating or other methods. This process can easily damage components, rendering them unusable, and requires specialized tools and techniques. The operation is cumbersome, time-consuming, and significantly increases material and labor costs. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a connection terminal.

[0006] The present invention discloses a connection terminal, comprising:

[0007] The conductor has a socket that is opened along the length of the conductor; one end of the conductor has a snap-fit ​​part that is detachably connected to a slot on the base; the end of the conductor away from the snap-fit ​​part is provided with multiple spring pieces that are spaced around the socket.

[0008] The sleeve is fitted onto the outer surface of the conductor; one end of the sleeve has multiple fixing pieces distributed at intervals, the multiple fixing pieces are bent toward the insertion hole, and the multiple fixing pieces abut against multiple spring pieces respectively;

[0009] A sealing body is disposed on the conductor, and the sealing body blocks the extension of the socket to the snap-fit ​​part.

[0010] According to one embodiment of the present invention, the overall shape of the snap-fit ​​part is a flat structure.

[0011] According to one embodiment of the present invention, the snap-fit ​​part is a single-layer or multi-layer plate structure.

[0012] According to one embodiment of the present invention, the conductor also has a limiting hole communicating with the socket, and a limiting piece is provided at the end of the sleeve away from the fixing piece, the limiting piece passing through the limiting hole and extending into the socket.

[0013] According to one embodiment of the present invention, the number of limiting pieces is two, and the two limiting pieces are distributed relatively at intervals.

[0014] According to one embodiment of the present invention, there are two limiting holes, which are distributed at intervals and opposite to each other, and four limiting pieces, with two limiting pieces distributed in each limiting hole.

[0015] According to one embodiment of the present invention, the sleeve is further provided with a plurality of support pieces, which are spaced apart and abut against the outer surface of a plurality of spring pieces respectively.

[0016] According to one embodiment of the present invention, the conductor is made of a material with high conductivity and high yield strength.

[0017] According to one embodiment of the present invention, the sleeve is made of stainless steel.

[0018] According to one embodiment of the present invention, the sealing body is made of silicone material.

[0019] The beneficial effects of this invention lie in the fact that the detachable connection between the snap-fit ​​part of the conductor and the slot of the base body significantly optimizes the installation and maintenance process. During installation, no welding process or specialized tools are required; assembly can be completed quickly simply by precisely fitting the snap-fit ​​part to the slot, reducing operational barriers and time costs.

[0030] 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. That is, in some embodiments of this utility model, these practical details are not essential.

They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0032] like Figure 1 and Figure 2 As shown, Figure 1 This is a three-dimensional structural diagram of the connecting terminals; Figure 2 This is another three-dimensional structural diagram of the connection terminal. The connection terminal includes a conductor 1, a sleeve 2, and a sealing body 3. The conductor 1 is used to connect with an external pin to conduct current. The sleeve 2 is fitted onto the outer surface of the conductor 1, which supports the conductor 1 and facilitates the connection of the connection terminal with other components. The sealing body 3 is disposed on the conductor 1, which prevents liquid from flowing into the interior of the conductor 1 and causing a short circuit.

[0033] Please refer to the following: Figure 3 As shown, Figure 3 This is a three-dimensional structural diagram of conductor 1. Conductor 1 has a socket 11, which starts along the length of conductor 1. An external pin is inserted into the socket 11, and current can be conducted between the external pin and conductor 1.

[0034] The conductor 1 has a snap-fit ​​portion 12 located at one end of the conductor 1. The snap-fit ​​portion 12 can be detachably connected to the slot (not shown in the figure) of the base (not shown), thereby facilitating the installation, disassembly, and maintenance of the conductor 1. A sealing body 3 is disposed between the two ends of the conductor 1. The sealing body 3 can block the extension of the socket 11 to the snap-fit ​​portion 12, thereby preventing liquid in the socket 11 from flowing along the wall of the socket 11 to the snap-fit ​​portion 12. Since the snap-fit ​​portion 12 is connected to the base, and the base is the part connected to the circuit, if liquid flows into the base along the wall of the socket 11, it will cause a short circuit and thus damage. Specifically, the overall shape of the snap-fit ​​portion 12 is flat, and the corresponding slot on the base is adapted to the shape of the snap-fit ​​portion 12. The snap-fit ​​part 12 can be a single-layer plate structure. Of course, in order to accommodate the thickness of the slot on the base, the snap-fit ​​part 12 can also be a structure composed of multiple layers of plates stacked together. In this embodiment, no specific limitation is made. In actual use, it can be changed according to the requirements.

[0035] The conductor 1 is also provided with a plurality of spring contacts 13, which are located at the end of the conductor 1 away from the locking part 12. The spring contacts 13 are distributed around the socket 11 and are spaced apart from each other. In specific applications, the spring contacts 13 can move relative to the conductor 1 to a certain extent. For example, when the external pin is inserted into the socket 11, the outer wall of the external pin exerts an outward force on the multiple spring contacts 13, which will push the multiple spring contacts 13 to move outward. At this time, the parts of the multiple spring contacts 13 that are not connected to the conductor 1 will move relative to the conductor 1.

[0036] Please refer to the following: Figure 4 and Figure 5 As shown, Figure 4 This is a schematic diagram of the three-dimensional structure of sleeve 2; Figure 5 This is another three-dimensional structural diagram of the sleeve 2. The sleeve 2 is provided with multiple fixing pieces 21, which are located at one end of the sleeve 2 and are spaced apart. All the fixing pieces 21 are bent into the insertion hole 11. At the same time, after bending, the fixing pieces 21 will abut against the multiple spring pieces 13. The fixing pieces 21 can prevent the sleeve 2 from slipping off the conductor 1.

[0037] Furthermore, the sleeve 2 is also provided with a limiting piece 22, which is engaged at the end of the sleeve 2 away from the fixing piece 21; the conductor 1 has a limiting hole 14, which communicates with the insertion hole 11. After the limiting piece 22 passes through the limiting hole 14, it extends into the insertion hole 11. Through the cooperation of the limiting hole 14 and the limiting piece 22, the sleeve 2 can be prevented from rotating relative to the conductor 1. Furthermore, there are two limiting pieces 22, which are distributed at an interval. Both limiting pieces 22 pass through the limiting hole 14 and extend into the insertion hole 11. The two limiting pieces 22 can limit the sleeve 2 in both clockwise and counterclockwise directions. In this embodiment, there are two limiting holes 14, which are distributed at an interval, and four limiting pieces 22. Two limiting pieces 22 are distributed in one limiting hole 14. In this way, the stability of the connection between the sleeve 2 and the conductor 1 can be further improved.

[0038] Preferably, the sleeve 2 is further provided with a plurality of support plates 23, which are spaced apart and abut against the outer surfaces of a plurality of spring pieces 13, thereby supporting the spring pieces 13. Specifically, when the external pin is inserted into the socket 11, the force of the external pin will cause the plurality of spring pieces 13 to expand outward. At this time, the plurality of support plates 23 provide a supporting force opposite to the force acting on the plurality of spring pieces 13. In this way, the positive force between the spring pieces 13 and the external pin can be effectively increased, which is beneficial to improving the current conduction effect and reducing the temperature rise.

[0039] In this embodiment, the conductor 1 is made of a material with high conductivity and high yield strength, such as copper; the sleeve 2 is made of a material with a certain supporting strength, such as stainless steel; and the sealing body 3 is made of a soft material, such as silicone.

[0040] In summary, the detachable connection formed between the snap-fit ​​part 12 of the conductor 1 and the slot of the base significantly optimizes the installation and maintenance process. Installation requires no welding or specialized tools; assembly is quick and easy simply by precisely fitting the snap-fit ​​part 12 to the slot, reducing operational barriers and time costs. For later maintenance and replacement, unlike welded structures which require heating for separation (avoiding high-temperature damage to components), the conductor 1 can be removed simply by disengaging the snap-fit. This demonstrates the advantages of this method: simple operation, reduced time consumption, and lower costs.

[0041] 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.
