Description

Technical Field

[0001] This invention relates to the field of strip connector technology, and in particular to a strip connector with a fault-proof structure. Background Technology

[0002] In the field of electronic equipment assembly, bar connectors, as key components for signal and power transmission, are widely used in industrial control, automotive electronics, consumer electronics and other scenarios. Their core function is to achieve circuit conduction through the precise mating of plugs and sockets. They usually need to meet the requirements of easy plugging and unplugging, connection stability and assembly efficiency, and adapt to the installation space and specification requirements of different equipment. Therefore, the structural design of plugs and sockets directly affects the overall connection reliability. Existing strip connector plug and socket guide structures are mostly symmetrical designs, lacking directional constraints. During manual assembly, visual deviations can cause the plug to shift laterally, leading to lateral misalignment during insertion, resulting in bent pins or damage to the housing. Furthermore, traditional connectors lack a clear orientation identification structure, causing reverse insertion when the plug and socket appear similar, leading to short circuits or signal transmission interruptions. To address these issues, existing technologies incorporate symmetrical guide grooves in the connector housing to mitigate lateral misalignment, while color markings or text labels aid in distinguishing the assembly direction. However, in practical use, the guide grooves cannot completely prevent lateral shifts, still requiring precise manual alignment; and color and text markings are susceptible to environmental interference, resulting in low reliability in error prevention.

[0003] A search revealed Chinese Patent Publication No. CN213782392U, which discloses a strip connector including a male and a female plug. The female plug has a fixing groove for the male plug to be inserted. Two parallel support plates are located on one side of the male plug, and a fixing plate is rotatably connected between the two support plates. The fixing plate includes a fixing part and an operating part along the mating direction of the male and female plugs. The fixing part is located on the side of the operating part closer to the female plug, and a locking block is provided on the side of the fixing part facing the male plug. A locking member that mates with the locking block is provided on the female plug. An operating groove is provided at one end of the female plug. The locking member includes an operating block and an elastic member disposed within the operating groove. The two ends of the elastic member are fixedly connected to the end face of the operating groove away from the opening and the elastic member itself, respectively. A limiting member is provided on the male plug to limit the rotation of the operating block. When the elastic member is not under force, the operating block extends out of the operating groove. When the male and female plugs mate, the locking block and the end face of the operating block away from the male plug abut against each other, which improves the service life of the male plug. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a strip connector with a fault-proof structure, which aims to improve the problems in the prior art that cannot completely avoid lateral offset, color and text markings are easily affected by the environment, and fault-proof reliability is low.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a strip connector with an anti-misalignment structure, comprising a female end and a male end. The inner wall of the female end and the left and right outer walls, top wall, and bottom wall of the male end are all equipped with anti-misalignment mechanisms. These mechanisms are used to prevent misalignment and directional installation. A clamping mechanism is installed inside and on the top outer side of the female end to increase connection stability. The anti-misalignment mechanism includes multiple positioning grooves, which are equidistantly spaced on the top wall of the male end. A cylindrical rail is fixedly connected to the left outer wall of the male end, and a triangular rail is fixedly connected to the right outer wall of the male end. A protrusion is fixedly connected to the left side of the top wall of the male end. A semi-circular hole is opened on the top front side of the female end, and a fastening assembly is installed inside the male end.

[0006] The above technical solution can initially prevent skewness and misalignment during insertion, while also adding a foolproof design to remind the operator of the correct installation direction.

[0007] As a further description of the above technical solution: The fastening assembly includes a movable pin, which is slidably connected inside the male end. A spring is fixedly connected to the bottom end of the movable pin, and a through hole is provided in the middle of the top wall of the female end.

[0008] The above technical solution can further stabilize the connection between the female and male ends, prevent slippage due to external forces and vibrations, and further prevent misaligned insertion.

[0009] As a further description of the above technical solution: The clamping mechanism includes an installation strip, which is slidably connected to the middle of the top wall of the female end. Multiple pressure blocks are fixedly connected at equal intervals to the top of the female end. Sliding tenons are fixedly connected to the bottom of both the left and right ends of the installation strip. Multiple movable components are installed at equal intervals in the upper middle part of the female end.

[0010] The above technical solution can achieve the compression of internal connections, thereby increasing the stability of the connection and its resistance to external interference through physical means.

[0011] As a further description of the above technical solution: The movable component includes multiple contact pieces, all of which are disposed inside the female end. A movable rod is fixedly connected to the middle of the top wall of each contact piece, and a spring is fixedly connected to the top of the movable rod. A sleeve is slidably connected to the upper middle part of the outer wall of the movable rod, and the sleeve is slidably connected to the middle of the top wall of the female end.

[0012] The above technical solution can increase the downward pressure while ensuring good electrical connection at the pressing point.

[0013] As a further description of the above technical solution: A circular groove is formed in the middle of the left side of the inner wall of the female end, and the cylindrical rail is slidably connected to the inner wall of the circular groove.

[0014] The above technical solution enables the cylindrical rail to be smoothly inserted into the female end, and controls the insertion direction.

[0015] As a further description of the above technical solution: A triangular groove is provided in the middle of the right side of the inner wall of the female end, and the triangular rail is slidably connected to the inner wall of the triangular groove.

[0016] The above technical solution enables the triangular rail to be smoothly inserted into the female end, and cooperates with the triangular rail to control the insertion direction.

[0017] As a further description of the above technical solution: The top wall of the female end is provided with sliding grooves on both the left and right sides, and the sliding tenon is slidably connected to the inner wall of the sliding groove.

[0018] With the above technical solution, the mounting strip can slide on the female end, the movement path is restricted, and it is not easy to fall off.

[0019] As a further description of the above technical solution: The bottom wall of the sub-end is fixedly connected with multiple positioning teeth at equal intervals, and the bottom wall of the sub-end is slidably connected to the inner bottom wall of the mother end through the positioning teeth.

[0020] The above technical solution adds auxiliary limiting and guiding measures to the bottom connection between the male and female ends, further increasing the accuracy of installation.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the positioning groove engages with the strip groove of the female end to initially prevent the male end from tilting or misaligning. The inner wall of the female end presses the moving pin, and when it reaches the through hole, the moving pin rebounds into the through hole under the elastic force of the spring to complete the lateral locking. The triangular rail and the cylindrical rail engage with the corresponding grooves on the inner wall of the female end to prevent the male end from being inserted in reverse. The protrusion and the semi-circular hole remind you to adjust the installation position. This mechanism prevents misalignment and misinsertion through multiple mechanisms, solving the problem that the existing technology cannot completely avoid lateral offset and has low reliability in preventing misalignment.

[0022] 2. In this utility model, after the wiring is completed, the mounting strip is pushed forward. The number of pressure blocks is the same as the number of wires. Under the action of the mounting strip, the pressure blocks press down on the corresponding sleeves. The sleeves move downward to squeeze the second spring and the moving rod. The moving rod drives the contact piece to press down on the joint to prevent vibration or external force from causing the connection to loosen. The contact piece is made of conductive material and has multiple anti-slip ridges evenly distributed on the bottom wall. This mechanism can increase the stability of the circuit connection between the two terminals and improve the resistance to external interference. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a strip connector with an anti-misalignment structure, including a female end 1 and a male end 4. The inner wall of the female end 1 and the left and right outer walls, top wall and bottom wall of the male end 4 are all equipped with anti-misalignment mechanisms 2. The anti-misalignment mechanisms 2 are used to prevent misalignment and directional installation. The inner and outer top of the female end 1 are equipped with clamping mechanisms 3. The clamping mechanisms 3 are used to increase the stability of the connection. The anti-misalignment mechanism 2 includes multiple positioning grooves 201 to guide the male end 4 to be inserted in a straight line. The multiple positioning grooves 201 are equidistantly opened on the top wall of the male end 4. A cylindrical rail 203 is fixedly connected to the left outer wall of the male end 4, and a triangular rail 202 is fixedly connected to the right outer wall of the male end 4. The two restrict the insertion direction to prevent reverse insertion. A protrusion 204 is fixedly connected to the left side of the top wall of the male end 4. A semi-circular hole 205 is opened on the top front side of the female end 1 to remind the user to adjust the installation position and direction when the insertion is reversed or misaligned. A fastening component 206 is installed inside the male end 4. The fastening assembly 206 includes a movable pin 2061, which is slidably connected to the inside of the female end 4. A spring 2062 is fixedly connected to the bottom end of the movable pin 2061, and a through hole 2063 is provided in the middle of the top wall of the female end 1. A circular groove 6 is provided in the middle of the left side of the inner wall of the female end 1, and a cylindrical rail 203 is slidably connected to the inner wall of the circular groove 6. A triangular groove 5 is provided in the middle of the right side of the inner wall of the female end 1, and a triangular rail 202 is slidably connected to the inner wall of the triangular groove 5. Specifically, the positioning grooves 201 on both outer walls of the male end 4 engage with the strip grooves on the inner wall of the female end 1. This interlocking of the grooves allows the male end 4 to be inserted linearly into the female end 1 along the extension direction of the strip grooves, preventing deviation during insertion and initially preventing the male end 4 from tilting or misaligning within the female end 1. When the male end 4 moves along the insertion direction to fit against the inner wall of the female end 1, the inner wall of the female end 1 contacts and presses against the end of the moving pin 2061 mounted on the side wall of the male end 4, thus allowing the moving pin to move. The movable pin 2061 retracts inward under pressure towards the inner part 4. During the retraction of the movable pin 2061, it compresses the spring 2062. When the inner part 4 continues to move, it drives the movable pin 2061 to the pre-set through hole 2063 on the inner wall of the female end 1. The compressive pressure of the inner wall of the female end 1 on the movable pin 2061 disappears. Under the action of the rebound force generated by the spring 2062 after being compressed, the movable pin 2061 rebounds outward into the through hole 2063. The engagement of the movable pin 2061 with the through hole 2063 completes the engagement between the female end 4 and the female end 1. The lateral locking of end 1 not only ensures a stable connection between the two but also enhances the anti-misalignment effect. The triangular rail 202 and cylindrical rail 203 are respectively located on the other two outer walls of the female end 4 and are designed as semi-cylindrical and triangular prisms, respectively. Their shapes match the corresponding grooves on both sides of the inner wall of the female end 1, and they can only engage with the corresponding grooves on both sides of the inner wall of the female end 1. This shape matching restricts the insertion direction of the female end 4, preventing it from being inserted in the opposite direction. Simultaneously, the protrusion 204 is fixedly installed on the top surface of the female end 4. The circular hole 205 is opened on the inner wall of the top surface of the female end 1. Both are only installed on the top surface of the corresponding parts, and the installation positions of the protrusion 204 and the semi-circular hole 205 are offset from the central axis of the male end 4 and the female end 1. When the male end 4 is inserted in the wrong direction or when the position is offset during the insertion process, the protrusion 204 on the male end 4 cannot be aligned with the semi-circular hole 205 on the female end 1 and inserted into the semi-circular hole 205, which causes the female end 1 and the male end 4 to not be fully connected. This serves as a reminder to the operator to adjust the installation position and insertion direction of the male end 4.

[0031] Reference Figure 1 , Figure 4 and Figure 5 The clamping mechanism 3 includes an installation strip 301, which is slidably connected to the middle of the top wall of the female end 1. Multiple pressure blocks 302 are fixedly connected at equal intervals to the top of the female end 1, which are used to press down on the corresponding sleeve 3044. Sliding tenons 303 are fixedly connected to the bottom of the left and right ends of the installation strip 301. Multiple moving components 304 are installed at equal intervals in the upper middle part of the female end 1. The movable assembly 304 includes multiple contact pieces 3041 for pressing the wiring connector to prevent the connection from loosening due to vibration or external force. The multiple contact pieces 3041 are all located inside the female end 1. A movable rod 3042 is fixedly connected to the middle of the top wall of the contact piece 3041. A second spring 3043 is fixedly connected to the top of the movable rod 3042 to provide additional downward pressure. A sleeve 3044 is slidably connected to the upper middle part of the outer wall of the movable rod 3042. Its function is to compress the second spring 3043 and the sleeve 3044 of the movable rod 3042 to be slidably connected to the middle of the top wall of the female end 1. The top wall of the female end 1 is provided with sliding grooves 7 on both the left and right sides, and the sliding tenon 303 is slidably connected to the inner wall of the sliding groove 7. Specifically, after the wiring between terminals is completed according to specifications, the operator holds the end of the mounting strip 301 and pushes it forward. Several pressure blocks 302 are fixed to the bottom surface of the mounting strip 301, and the number of pressure blocks 302 is the same as the number of wires connected to the terminals. Driven by the forward movement of the mounting strip 301 along the guide rail, the pressure blocks 302 move downwards simultaneously, pressing the top of the corresponding sleeve 3044. Under pressure, the sleeve 3044 moves downwards vertically. During this movement, the bottom end of the sleeve 3044 simultaneously squeezes the spring 3043 sleeved on its outer side and the moving rod 3042 penetrating inside the sleeve 3044. The bottom end of the moving rod 3042 contacts the contact piece 3041. The upper surface is fixedly connected, which in turn drives the contact piece 3041 to move downward. The lower surface of the contact piece 3041 contacts the connector of the wiring and presses the connector tightly. The continuous pressure prevents the connection from loosening due to vibration caused by the operation of the equipment or external force. The contact piece 3041 is made of conductive material, and multiple raised anti-slip ridges are evenly distributed on its bottom wall. The anti-slip ridges contact the surface of the connector to increase friction. This mechanism can increase the stability of the circuit connection between the two terminals through the cooperation of the pressure block 302, the sleeve 3044, the moving rod 3042 and the contact piece 3041. The pressing of the contact piece 3041 and the anti-slip ridges enhance the resistance of the circuit connection to external interference.

[0032] Reference Figure 1 and Figure 2 The bottom wall of the male end 4 is fixedly connected with multiple positioning teeth 8 at equal intervals, and the bottom wall of the male end 4 is slidably connected to the inner bottom wall of the female end 1 through the positioning teeth 8. Specifically, the number of positioning teeth 8 is the same as the number of connectors in the female end 1 and the female end 4, and the bottom wall of the female end 1 has a groove with the same length and width as the teeth, which can be slid into it.

[0033] Working principle: The positioning groove 201 engages with the strip groove on the female end 1, allowing the male end 4 to be inserted linearly into the female end 1. This initially prevents the male end 4 from being skewed or misaligned within the female end 1. Once the male end 4 is fully inserted, the inner wall of the female end 1 presses against the moving pin 2061, causing the moving pin 2061 to retract under pressure inside the female end 1 and compress the spring 2062. When the male end 4 moves the moving pin 2061 to the through hole 2063, the pressure on the female end 1 disappears, and the moving pin 2061 springs back into the through hole 2063 under the elastic force generated by the spring 2062, completing the lateral locking. This not only secures the connection but also further enhances the anti-misalignment effect. The triangular rail 202 and the cylindrical rail 203 are designed as semi-cylindrical and triangular prisms, respectively. They can only be engaged with the corresponding grooves on both sides of the inner wall of the female end 1 to prevent the male end 4 from being inserted in the opposite direction. At the same time, the protrusion 204 and the semi-circular hole 205 are only installed on the top surface and are off the central axis. When the insertion is reversed or misalignment occurs during the insertion process, the protrusion 204 cannot be embedded in the semi-circular hole 205, and the female end 1 and the male end 4 cannot be joined, reminding the operator to adjust the installation position. This mechanism prevents misalignment and misinsertion through multiple mechanisms, solving the problems of existing technologies that cannot completely avoid lateral offset, color and text markings are easily affected by the environment, and low reliability of error prevention. After the wiring is completed, push the mounting strip 301 forward. The number of pressure blocks 302 is the same as the number of wires. Driven by the mounting strip 301, the pressure blocks 302 press down on the corresponding sleeves 3044. The sleeves 3044 move downward, squeezing the spring 3043 and the moving rod 3042. The moving rod 3042 drives the contact piece 3041 downward to press the joint tightly, preventing the connection from loosening due to vibration or external force. The contact piece 3041 is supported by conductive material, and multiple anti-slip ridges are evenly distributed on the bottom wall. This mechanism can increase the stability of the circuit connection between the two terminals and improve the resistance to external interference.
