Description

Technical Field

[0001] This utility model relates to the field of heavy-duty connector installation technology, and in particular to a heavy-duty connector with an anti-misfit positioning structure. Background Technology

[0002] With the continuous improvement of industrial automation and intelligence, heavy-duty connectors are playing an increasingly important role in fields such as machinery, power systems, and transportation. These connectors typically need to transmit large currents, high voltages, or a large number of signals, thus placing higher demands on their connection reliability, ease of operation, and structural stability. In practical applications, the insertion and removal operations of heavy-duty connectors often require significant force. This is mainly because the moving parts inside the connector inevitably experience sliding friction during their extension and retraction. This significant sliding friction not only increases the workload of operators and reduces operational efficiency but may also accelerate wear on the connector during frequent insertion and removal. This affects their service life. In addition, in the design of heavy-duty connectors, the control of the movement stroke of key moving parts such as the connecting rod is also crucial. If there is a lack of effective limiting and guiding structures, the connecting rod may be inaccurately positioned, excessively slip out, or even detach from the body during movement. This will not only affect the reliability of the connection, but may also cause equipment damage or operational safety hazards. When solving these problems, existing technologies often adopt relatively simple friction reduction solutions or simple limiting structures, which are difficult to ensure smooth operation while taking into account the precise guidance and reliable limiting of moving parts. As a result, heavy-duty connectors still have problems with poor operation experience and relatively high failure risk in actual use.

[0003] Therefore, this utility model proposes a heavy-duty connector with an anti-misfit positioning structure to overcome the shortcomings of the prior art. Utility Model Content

[0004] In view of the problems existing in the prior art, such as the large sliding friction between the internal moving parts of the heavy-duty connector, which makes the insertion and removal operation difficult and the process is not smooth, and the stroke control of the moving parts is not precise enough, which poses a risk of dislodgement, this utility model aims to provide a heavy-duty connector with an improved structure that can effectively solve the above problems and has an anti-misinsertion positioning structure.

[0005] This utility model provides a heavy-duty connector with an anti-misinsertion positioning structure, including a connector body, a fixing frame installed on the connector body, a top cover covering the fixing frame, a sliding sleeve slidably disposed in the fixing frame, and a connecting rod slidably disposed in the sliding sleeve; it also includes a sliding bar, a sliding groove, a rolling ball, a first limiting ring, and a second limiting ring.

[0006] The top cover has a sliding strip fixed to its inner side, and the mounting bracket has a groove that mates with the sliding strip.

[0007] Furthermore, the sliding bar and the sliding groove are combined by accommodating rolling balls to form a rolling friction mechanism; at the same time, the outer wall of the sliding sleeve is provided with a limiting ring one to prevent it from sliding out of the fixed frame, and the outer wall of the connecting rod is provided with a limiting ring two to cooperate with the top cover to limit its sliding range. Through this double limiting structure, the sliding sleeve and the connecting rod are accurately positioned.

[0008] Preferably, the sliding bar has a semi-circular groove for accommodating the rolling ball, and a clamping block is fixed between the semi-circular grooves to prevent the rolling ball from falling out.

[0009] Preferably, the sliding bar, sliding groove, semi-circular groove, clamping block, and rolling ball together constitute an installation mechanism, which is used to achieve low-friction sliding of the top cover on the fixed frame.

[0010] Preferably, the sliding strips are fixedly connected to the left and right sides of the interior of the top cover, and the sliding grooves corresponding to the sliding strips are opened on the left and right sides of the fixing frame.

[0011] Preferably, the limiting ring is installed in the middle of the outer wall of the sliding sleeve.

[0012] Preferably, the limiting ring 2 is installed in the middle of the outer wall of the connecting rod.

[0013] Preferably, the connecting rod slides within the sliding sleeve along its own axial direction.

[0014] Preferably, the fixed frame, sliding sleeve, limiting ring one, connecting rod, and limiting ring two together constitute an anti-misinsertion mechanism, which is used to guide, position, and limit the stroke of the connecting rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model solves the problem of difficult operation and unsmooth process caused by large sliding friction force during the insertion and removal of existing heavy-duty connectors by setting a rolling friction mechanism composed of sliding strips, sliding grooves and rolling balls between the top cover and the fixed frame. It achieves the technical effect of significantly reducing operating resistance and making the extension and retraction of the connecting rod smoother and less laborious.

[0017] 2. This utility model solves the problems of inaccurate stroke control of the moving parts of existing connectors and the risk of excessive sliding and disengagement by setting a sliding sleeve that can slide within a fixed frame and a connecting rod that can slide within the sliding sleeve, and by using limit ring one and limit ring two to limit the sliding stroke of the sliding sleeve and the connecting rod respectively. It achieves the technical effect of stable guidance and precise positioning of the extension and retraction process of the connecting rod, and improves the structural stability and operational reliability.

[0018] 3. This utility model has an ingenious overall structural design, which coordinates the rolling friction mechanism with the double limit sliding mechanism. The positioning of each component is clear and the connection is reliable. This not only ensures the convenience of operation, but also ensures the stability and safety of the structure itself, and enhances the practicality and durability of the heavy-duty connector.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Example:

[0027] Please refer to Figures 1 to 4 This utility model provides a heavy-duty connector with an anti-misfit positioning structure, which aims to solve the problems of difficult insertion and removal operations, unsmooth process, and risk of internal moving parts coming out of existing heavy-duty connectors.

[0028] like Figure 1 and Figure 2 As shown, the heavy-duty connector with anti-misfit positioning structure includes a connector body 1 and a fixing frame 31 installed on the top of the connector body 1. The connector body 1 serves as the mounting base for the entire device, and the fixing frame 31 serves as the supporting base for components such as the sliding sleeve 32. The heavy-duty connector further includes a top cover 2 covering the fixing frame 31. The top cover 2 is used to protect the components inside the fixing frame 31. Multiple sliding sleeves 32 are slidably connected to the bottom inside the fixing frame 31, and multiple connecting rods 34 are slidably connected inside the multiple sliding sleeves 32.

[0029] To solve the above-mentioned technical problems, the technical solution of this embodiment is that the heavy-duty connector with anti-misfit positioning structure further includes a mounting mechanism 4 for achieving low-friction sliding and an anti-misfit mechanism 3 for achieving precise positioning, and a specific structural cooperation and connection relationship is formed between the mounting mechanism 4 and the anti-misfit mechanism 3.

[0030] Please refer to the following carefully. Figures 2 to 4 The structure will be described in detail below:

[0031] The top cover 2 has sliding strips 41 fixedly connected to the mounting mechanism 4 on both the left and right sides. The fixing frame 31 has grooves 42 on both the left and right sides that slide with the sliding strips 41. A semi-circular groove 43 is formed between adjacent sliding strips 41, and a clamping block 44 is fixedly connected between adjacent semi-circular grooves 43. Rolling balls 45 are placed between adjacent clamping blocks 44 to prevent them from falling off. There are two rolling balls 45 on each side. The rolling balls 45 are housed between the sliding strips 41 and the grooves 42. The rolling balls 45 move to keep the top cover 2 and the fixing frame 31 connected. The sliding friction is converted into rolling friction. This rolling fit structure ensures low resistance and high smoothness during the reciprocating motion of the top cover 2 on the fixed frame 31. At the same time, a limit ring 33 is installed in the middle of the outer wall of each sliding sleeve 32. The limit ring 33 and the fixed frame 31 are used to prevent the sliding sleeve 32 from sliding out of the fixed frame 31 during the sliding process. A limit ring 35 is installed in the middle of the outer wall of each connecting rod 34. The limit ring 35 and the inner surface of the top cover 2 are used to prevent the connecting rod 34 from sliding out of the top cover 2. The connecting rod 34 slides inside the sliding sleeve 32 along its own axis.

[0032] Based on the above embodiments, the technical solution of this utility model can be further configured as follows:

[0033] As a specific implementation, sliding strips 41 are fixedly connected to the left and right sides of the inside of the top cover 2, and sliding grooves 42 corresponding to the sliding strips 41 are opened on the left and right sides of the fixing frame 31. This symmetrical arrangement structure makes the force on the top cover 2 more uniform and the movement more stable during the sliding process. The sliding strips 41, sliding grooves 42, semi-circular grooves 43, clamping blocks 44 and rolling balls 45 together constitute the mounting mechanism 4. The mounting mechanism 4 as a whole is used to realize the low-friction sliding of the top cover 2 on the fixing frame 31.

[0034] As another specific implementation, the limiting ring 33 is specifically installed in the middle of the outer wall of the sliding sleeve 32, and the limiting ring 35 is specifically installed in the middle of the outer wall of the connecting rod 34. This central setting helps to provide more stable support when limiting. The fixing frame 31, the sliding sleeve 32, the limiting ring 33, the connecting rod 34 and the limiting ring 35 together constitute the anti-misinsertion mechanism 3. The anti-misinsertion mechanism 3 as a whole is used to guide, position and limit the stroke of the connecting rod 34.

[0035] Working principle: First, the fixed frame 31 inside the anti-misinsertion mechanism 3 is installed on the top of the connector body 1 as a supporting base for components such as the sliding sleeve 32. Then, multiple sliding sleeves 32 are slidably connected to the bottom inside the fixed frame 31, allowing the sliding sleeves 32 to slide smoothly within the fixed frame 31. A limiting ring 33 is installed in the middle of the outer wall of each sliding sleeve 32. The cooperation between the limiting ring 33 and the fixed frame 31 effectively prevents the sliding sleeve 32 from sliding out of the fixed frame 31 during the sliding process. Then, multiple connecting rods 34 are slidably connected to the inside of the multiple sliding sleeves 32, allowing the connecting rods 34 to slide along the axial direction of the sliding sleeve 32. A limiting ring 35 is installed in the middle of the outer wall of each connecting rod 34. The cooperation between the limiting ring 35 and the top cover 2 prevents connection errors. The plug rod 34 slides out of the top cover 2, and then the top cover 2 is installed on the top of the connector body 1, so that the top cover 2 covers the fixing frame 31, forming a protective layer for the internal sliding sleeve 32 and the components connecting the plug rod 34; at the same time, sliding strips 41 of the mounting mechanism 4 are fixedly connected to the left and right sides of the inside of the top cover 2, and sliding grooves 42 are opened on the left and right sides of the fixing frame 31, so that the sliding strips 41 can slide in cooperation with the sliding grooves 42; semi-circular grooves 43 are opened between adjacent sliding strips 41, and clamping blocks 44 are fixedly connected between adjacent semi-circular grooves 43; rolling balls 45 are placed between adjacent clamping blocks 44, and the clamping blocks 44 prevent the rolling balls 45 from falling off. There are two rolling balls 45 on each side, which can change sliding friction into rolling friction and reduce the friction force during sliding.

[0036] When the connecting rod 34 is needed, push the connecting rod 34 downwards. The connecting rod 34 slides inside the sliding sleeve 32. At this time, the second limiting ring 35 moves with the connecting rod 34. Due to the restriction of the top cover 2, the second limiting ring 35 will drive the connecting rod 34 to slide within a suitable range. At the same time, the sliding sleeve 32 will also slide inside the fixing frame 31. The first limiting ring 33 prevents the sliding sleeve 32 from sliding out of the fixing frame 31 excessively, ensuring that the connecting rod 34 can extend smoothly for connection operation. During this process, the sliding strip 41 inside the top cover 2 slides along the sliding groove 42 of the fixing frame 31. The rolling ball 45 in the semi-circular groove 43 of the sliding strip 41 rolls accordingly, converting the sliding friction between the sliding strip 41 and the sliding groove 42 into rolling friction, greatly reducing the friction force during sliding, and making the extension operation of the connecting rod 34 smoother.

[0037] After connection is completed, to retract the connecting rod 34, pull the connecting rod 34 upwards. The connecting rod 34 slides inside the sliding sleeve 32. The second limiting ring 35 cooperates with the top cover 2 to limit the sliding range of the connecting rod 34. The sliding sleeve 32 will also slide inside the fixed frame 31. The first limiting ring 33 ensures that the sliding sleeve 32 is stable inside the fixed frame 31, so that the connecting rod 34 can be retracted smoothly and stored inside the device. At the same time, the sliding strip 41 inside the top cover 2 slides in the opposite direction along the sliding groove 42, and the rolling ball 45 continues to roll, maintaining a small friction force, so that the retraction operation of the connecting rod 34 is also smooth.
