Description
Technical Field
[0001] This utility model relates to the field of welding technology, and in particular to a cable clamp. Background Technology
[0002] Currently, the cable clamp has a slot for inserting into the PCB (circuit board). The back claws of the cable clamp are first manually soldered to the back of the PCB for grounding and fixation.

[0003] When using automated soldering (such as reflow soldering cable clamps to PCB back pads), the gap between the cable clamp and the PCB can cause solder paste to flow onto the front of the PCB and into the cable holes during reflow soldering, thus affecting soldering efficiency and product quality.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] like Figures 1-9As shown, this embodiment provides a cable clamp for connecting a cable to a circuit board 100. The cable clamp includes a clamp body 1, a first limiting member 2, and a second limiting member 3. The clamp body 1 has a working channel 11 that extends through a first direction. The first limiting member 2 is disposed on the clamp body 1, and the second limiting member 3 is disposed on the clamp body 1. A limiting groove 31 is formed between the second limiting member 3 and the first limiting member 2. The limiting groove 31 is used to insert the circuit board 100. The plane on which the circuit board 100 is located divides the working channel 11 into a wire-passing channel 111 and an overflow channel 112. The cable core 201 can pass through the wire-passing channel 111 and be connected to one side of the circuit board 100. The first limiting member 2 abuts against the other side of the circuit board 100. The first limiting member 2 and the circuit board 100 can cover the overflow channel 112.
[0037] In this embodiment, the clamp 1 has a working channel 11 extending along a first direction to provide space for cables to pass through. A first limiting member 2 is disposed on the clamp 1, stably supporting and connecting to the other side of the circuit board 100, improving the stability and reliability of the welding process. A limiting groove 31 is formed between the second limiting member 3 and the first limiting member 2. The limiting groove 31 is used to insert the circuit board 100, ensuring that the circuit board 100 can be accurately inserted into the limiting groove 31, preventing the circuit board 100 from moving or misaligning during the welding process, thereby improving the accuracy and efficiency of the welding. When the circuit board 100 is inserted into the limiting slot 31, the plane on which the circuit board 100 is located divides the working channel 11 into a wire-passing channel 111 and an overflow channel 112. The cable core 201 can pass through the wire-passing channel 111 and connect to one side of the circuit board 100. The first limiting member 2 abuts against the other side of the circuit board 100. The first limiting member 2 and the circuit board 100 can seal the overflow channel 112, so that the solder paste is blocked in time by the first limiting member 2 and the circuit board 100 during the soldering operation and will not flow to other places through the overflow channel 112. With the above settings, the cable clamp of this embodiment can achieve efficient installation with the circuit board 100, resulting in higher product quality.
[0038] It should be noted that, as Figure 9 As shown, the end face of the circuit board 100 along its own thickness direction and the first limiting member 2 can cover the overflow channel 112, so that the solder paste is blocked in time by the first limiting member 2 and the circuit board 100 during the soldering operation and will not flow to other places through the overflow channel 112.
[0039] The specific structure of the cable clamp is explained below:
[0040] Specifically, such as Figure 1 and Figure 2As shown, in this embodiment, the first limiting member 2 is a limiting block, and the second limiting member 3 is a claw. The limiting block and the claw are disposed at one end of the clamping body 1, and a limiting groove 31 is formed between the claw and the limiting block. The circuit board 100 can be inserted into the limiting groove 31 along the first direction, so that the circuit board 100 is more stable during the welding process.
[0041] Specifically, such as Figure 3 and Figure 4 As shown, in this embodiment, the first limiting member 2 is provided with a protrusion 21. The protrusion 21 extends in a direction away from the clamping body 1 and is parallel to and spaced apart from the second limiting member 3. The circuit board 100 can be inserted between the second limiting member 3 and the protrusion 21. Through the cooperation of the protrusion 21 and the second limiting member 3, the circuit board 100 can be effectively limited and fixed when inserted, preventing the circuit board 100 from moving or misaligning during the soldering process. Moreover, the protrusion 21 extends in a direction away from the clamping body 1, which can play a certain guiding role in the insertion of the circuit board 100, making it easier for the circuit board 100 to be inserted into the limiting groove 31. The protrusion 21 can be a claw or a limiting block, that is, as long as it can achieve the above-mentioned functions, the specific structure of the protrusion 21 is not limited here.
[0042] More specifically, such as Figure 3 As shown, multiple protrusions 21 are provided, and the multiple protrusions 21 are spaced apart along the second direction, so that the circuit board 100 can be supported and guided by the multiple protrusions 21 when it is inserted into the limiting groove 31, thereby improving the overall stability of the cable clamp and the circuit board 100 during installation.
[0043] More specifically, in this embodiment, there are two protrusions 21, which are respectively located at both ends of the first limiting member 2 along the second direction. This ensures that the circuit board 100 receives balanced support and fixation when inserted, and also facilitates stable soldering of the protrusions 21 to the other side of the circuit board 100. In other embodiments, there are three, four, or five protrusions 21. The specific number can be adjusted according to the specific installation requirements of the circuit board 100 and the cable clamp, and is not limited here.
[0044] Specifically, such as Figure 3 and Figure 4 As shown, the end of the protrusion 21 away from the clamp 1 is provided with a first guide surface 211. The first guide surface 211 is set toward the second limiting member 3. Along the direction away from the clamp 1, the first guide surface 211 gradually moves away from the second limiting member 3. This setting can guide the circuit board 100 to be smoothly inserted into the limiting groove 31, while reducing the frictional resistance during insertion.
[0045] Specifically, such as Figures 1-6As shown, in this embodiment, there are two second limiting members 3. The two second limiting members 3 are respectively set on both sides of the opening end of the working channel 11. This can ensure that the second limiting members 3 do not interfere with the cable threading operation, and also ensure that when the circuit board 100 is inserted into the limiting groove 31, both ends of the circuit board 100 can be stably supported and limited, which further improves the stability and welding accuracy of the circuit board 100.
[0046] More specifically, such as Figure 3 and Figure 4 As shown, the second limiting member 3 has a second guide surface 32 at the end away from the clamping body 1. The second guide surface 32 is positioned towards the first limiting member 2, and gradually moves away from the first limiting member 2 in the direction away from the clamping body 1. This arrangement guides the circuit board 100 to be smoothly inserted into the limiting groove 31, while reducing frictional resistance during insertion. It is understood that the first guide surface 211 and the second guide surface 32 in this embodiment can be manufactured with reference to the chamfering process, which will not be elaborated further here.
[0047] Specifically, such as Figures 1-6 As shown, the cable clamp also includes a guide 4, a first limiting member 2 and a second limiting member 3 disposed at one end of the clamp body 1, and a guide 4 disposed at the other end of the clamp body 1, and has a guide channel 41 connected to the working channel 11. After the circuit board 100 is inserted into the limiting groove 31 at one end of the clamp body 1, the other side of the circuit board 100 is welded and fixed to the first limiting member 2 by automated welding. The cable conductor 202 can pass through the guide channel 41 from the other end of the clamp body 1 along the first direction, so that the cable core 201 can be directly welded to the wired part on one side of the circuit board 100 to realize batch welding operations and improve welding efficiency. Moreover, the guide channel 41 extends along the first direction and is configured to carry the cable conductor 202. This configuration not only facilitates the carrying of the cable conductor 202, but also guides the cable conductor 202 to a certain extent, improving the accuracy and stability of welding.
[0048] Specifically, such as Figures 3-8As shown, in this embodiment, the guide 4 includes multiple guide blocks 42, which are spaced apart circumferentially along the working channel 11 to form a guide channel 41. This ensures the uniformity and continuity of the guide channel 41 in the circumferential direction, providing stable guidance for the cable conductor 202. This allows the cable core 201 located at the axis of the cable conductor 202 to be better connected and installed with the circuit board 100 via the cable clamp. In other embodiments, the guide 4 is an arc-shaped plate, with multiple arc-shaped plates spaced apart circumferentially along the working channel 11 to form a guide channel 41 with a circular cross-section. This better adapts to the shape of the cable conductor 202 and prevents the cable conductor 202 from coming out of the cable clamp. It is understood that the specific structure of the guide 4 is not limited, as long as it can achieve the above-mentioned functions.
[0049] Specifically, such as Figure 1 , Figure 4 , Figure 8 and Figure 9 As shown, there are two guide blocks 42. The distance between one adjacent end of the two guide blocks 42 is a first distance value, and the distance between the other adjacent ends is a second distance value. The first distance value is greater than the second distance value. It can be understood that the guide 4 has a first opening and a second opening. The size of the first opening is the first distance value, and the size of the second opening is the second distance value. The size of the first opening is greater than the size of the second opening, so as to facilitate the automated soldering of the robotic arm, eliminating the need for manual soldering by operators, improving soldering efficiency, and making it easier to observe the soldering quality between the cable conductor 202 and the guide 4.
[0050] Specifically, such as Figure 6 and Figure 9 As shown, the first distance value is less than the diameter of the cable conductor 202 to ensure the stability of the cable conductor 202 during welding and to prevent it from coming out through the opening between the guide blocks 42.
[0051] The following explains the specific working process of the cable clamp:
[0052] First, the circuit board 100 is inserted into the limiting slot 31. At this time, the plane on which the circuit board 100 is located divides the working channel 11 into a wire-passing channel 111 and an overflow channel 112, so that the cable core 201 can pass through the wire-passing channel 111 and connect to one side of the circuit board 100. Then, the other side of the circuit board 100 is soldered to the first limiting member 2 through automated soldering. The first limiting member 2 can cover the overflow channel 112 and abut against the other side of the circuit board 100, so that the solder paste is blocked by the first limiting member 2 in time during the soldering operation and will not flow to other places through the overflow channel 112, thereby improving the soldering quality and work efficiency. Then, the cable conductor 202 is passed through the guide channel 41, so that the cable core 201 can be directly soldered to the wired part on one side of the circuit board 100. Then, the cable conductor 202 is soldered to the guide member 4, thereby realizing batch soldering operation and improving soldering efficiency.
[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
