Description

Technical Field

[0001] This utility model relates to the field of connectors, and more specifically, to a plug-in connection structure for connectors. Background Technology

[0002] Connectors are widely used devices in various equipment circuits, mainly consisting of male and female terminals. When connected, they can transmit signals or circuits. For example, the connector disclosed in Chinese patent application publication number CN119133939A, entitled "A Plug and Socket Connector for Automotive Wiring Harnesses and a Connection Method," mainly includes a first connector, a second connector, a fixed sleeve, and a handle. The second connector is fixedly connected to the fixed sleeve, and the handle is rotatably connected to the fixed sleeve. When the handle is turned, a relative movement occurs between the drive groove on the handle and the driven shaft of the first connector, causing the first and second connectors to move towards or away from each other, thereby connecting or disconnecting the connector. When connecting this connector by turning the handle, the force applied by the hand is concentrated on one side of the handle, resulting in uneven force distribution. This has little impact on smaller connectors, but for larger connectors, it can easily cause the second connector to tilt to one side, increasing interference resistance and making connection difficult. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides a plug-in connection structure that can reduce interference resistance in connector connections.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A plug-in connection structure for a connector includes a female end, a male end that can be plugged into the female end, and a handle for driving the male end to move towards or away from the female end. The male end has an elastic friction block that protrudes into the male end on the side where the handle rotates towards the female end. The female end has a friction surface on the side corresponding to the friction block. The friction surface gradually slopes outward from the female end from top to bottom.

[0006] In a further improved technical solution, the female end is also provided with friction strips on both sides of the friction surface, which can clamp the friction block.

[0007] A further improved technical solution is that the bottom of the male end is provided with a chamfer for guiding the friction strip to clamp the friction block.

[0008] In a further improved technical solution, the surface of the friction block that contacts the friction surface is an inclined surface, and the inclined surface gradually slopes inward from bottom to top towards the inside of the male end.

[0009] A further improved technical solution is that the handle has a "∩" shaped structure and its two ends are respectively rotatably connected to both sides of the male end. The two ends of the handle are also provided with symmetrical elastic locking blocks. When the handle is rotated to insert the male end into the female end, the locking blocks on both sides are locked into the top surface of the male end.

[0010] In a further improved technical solution, the male end is provided with slots on both sides. When the handle is rotated to disconnect the male end from the female end, the slots on both sides are engaged in the slots on both sides.

[0011] A further improved technical solution is provided in which short posts are provided on both sides of the male end, and through holes that can be connected to the corresponding short posts are provided on both sides of the handle. The end of the short post can also be detachably and fixedly connected to a first stop block larger than the diameter of the through hole.

[0012] A further improved technical solution is provided in which guide grooves are provided on both sides of the handle, and guide posts that can be connected to the corresponding guide grooves are provided on both sides of the female end. The end of the guide post can also be detachably and fixedly connected to a second stop block that is wider than the guide groove.

[0013] In summary, the beneficial effects of this utility model are as follows: An elastic friction block is provided on the male end side, and a friction surface is provided on the corresponding female end side. During the process of rotating the handle to connect the male and female ends, the friction block and the friction surface are in close contact, generating a large frictional force. This frictional force is on the same side as the direction of handle rotation, which can to a certain extent offset the torque generated by the unbalanced force on the handle, reduce the degree of tilt of the male end relative to the female end, thereby reducing interference resistance during the connection process and improving the smoothness of the connection.

[0019] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

When a component is referred to as being "connected to" another component, it can be directly or indirectly connected to that other component.

Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0023] Reference Figures 1 to 3 A plug-in connection structure for a connector includes a female end 1, a male end 22 that can be plugged into the female end 1, and a handle 3 for moving the male end 22 towards or away from the female end 1. In this embodiment, the handle 3 has a "∩" shaped structure, and the two ends of the handle 3 are respectively rotatably connected to both sides of the male end 2.

[0024] In one embodiment, reference is made to Figure 1 and Figure 2 Both sides of the male end 2 are provided with short posts, and both sides of the handle 3 are provided with through holes that can be connected to the corresponding short posts. A first stop 21 larger than the diameter of the through hole can also be detachably and fixedly connected to the end of the short post. Preferably, the first stop 21 is fixedly connected to the end of the short post with screws. Using screws to fix the first stop 21 facilitates its installation during production and ensures installation strength.

[0025] In one embodiment, reference is made to Figure 1 and Figure 2The handle 3 has guide grooves 31 on both sides, and the female end 1 has guide posts on both sides that can be connected to the corresponding guide grooves 31. The ends of the guide posts can also be detachably and fixedly connected to a second stop block 11 that is wider than the guide groove 31. Similarly, the second stop block 11 is fixedly connected with screws to ensure the strength of the installation.

[0026] To ensure that the handle 3 does not reverse and cause the connection between the male end 2 and the female end 1 to become loose when the male end 2 is inserted, symmetrical elastic locking blocks 32 are provided at both ends of the handle 3. When the handle 3 is rotated to insert the male end 2 and the female end 1, the locking blocks 32 on both sides engage with the top surface of the male end 2. By locking the top surface of the male end 2 with the locking blocks 32, the handle 3 is effectively prevented from reversing on its own.

[0027] In addition, slots 22 are provided on both sides of the male end 2. When the handle 3 is rotated to disconnect the male end 2 from the female end 1, the locking blocks 32 on both sides are respectively engaged in the slots 22 on both sides. After the locking blocks 32 are engaged with the slots 22, the handle 3 remains at the current angle, so that the guide post can be aligned with the opening through the side wall of the handle 3 during insertion and smoothly enter the guide groove 31.

[0028] In one embodiment, reference is made to Figure 2 and Figure 3 The male end 2 has an elastic friction block 23 protruding inward on the side where the handle 3 rotates towards the female end 1. A friction surface 12 is provided on the side of the female end 1 corresponding to the friction block 23, and the friction surface 12 gradually slopes outward from top to bottom. Furthermore, the surface of the friction block 23 that contacts the friction surface 12 is an inclined plane, which also gradually slopes inward from bottom to top towards the male end 2. Both the friction block 23 and the friction surface 12 are designed as inclined planes to allow for better contact. Simultaneously, the friction surface 12 gradually slopes outward from top to bottom towards the female end 1. The greater the downward slope of the male end 2, the greater the deformation of the friction block 23, resulting in greater friction between the friction block 23 and the friction surface 12. Since the torque generated by the unbalanced force on the handle 3 also gradually increases with the rotation angle, this inclined plane can better counteract the torque generated by the unbalanced force on the handle 3.

[0029] In one embodiment, reference is made to Figure 2 and Figure 3 The female end 1 is further provided with friction strips 13 on both sides of the friction surface 12 to clamp the friction block 23. The friction strips 13 can increase the friction force and also play a role in preventing mistake-through. In addition, the bottom of the male end 2 is provided with a chamfer 24 to guide the friction strips 13 to clamp the friction block 23 and ensure smooth connection.

[0030] This invention provides an elastic friction block 23 on the side of the male end 2 and a friction surface 12 on the corresponding side of the female end 1. During the process of rotating the handle 3 to connect the male end 2 and the female end 1, the friction block 23 and the friction surface 12 are in close contact to generate a large friction force. This friction force is on the same side as the rotation direction of the handle 3, which can offset the torque generated by the unbalanced force on the handle 3 to a certain extent, reduce the tilt of the male end 2 relative to the female end 1, and thus reduce the interference resistance in the connection process.

[0031] The above embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to the embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
