Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a flip cover retention structure of a connector and a flip cover connector. Background Art

[0002] Flip-top connectors with flip covers need to be closed during transportation and storage to prevent foreign objects from entering the connector. During installation, the flip covers need to be opened and kept in a fixed position to prevent the flip covers from moving freely and interfering with the connection when tightening the bolts to lock the connector.

[0003] Currently, the flip cover of the flip connector needs to be connected to the connector body through a rotating shaft. Moreover, if the flip cover is to be fully stationary, that is, the flip cover is to be kept in any position in the open state, other components need to be used to position the rotating shaft. As a result, the connection between the flip cover and the connector body, especially the connection that can achieve full stationary state, requires many components and is inconvenient to assemble. Utility Model Content

[0004] The utility model aims to provide a flip cover retaining structure of a connector and a flip cover connector, which adopt an integrated structure and can realize the full-process retaining of the flip cover on the connector body without redundant parts.

[0005] To achieve the above-mentioned object, the technical solution adopted by the present invention is as follows: a flip cover retaining structure of a connector, comprising a hook and a retaining claw integrally formed on the connector body, and a rotating shaft integrally formed on the flip cover; the hook and the retaining claw are spaced apart, and the hook and the retaining claw are respectively provided with a first rotating groove and a second rotating groove with openings facing the same direction; the rotating shaft of the flip cover comprises a hook rotating shaft and a claw rotating shaft spaced apart, the hook rotating shaft being rotatably connected to the first rotating groove, and the claw rotating shaft being rotatably disposed in the second rotating groove;

[0006] The end of the hook and the outer shell of the connector body form a notch of the first rotation groove, and the opening width of the notch of the first rotation groove is smaller than the diameter of the hook rotation shaft;

[0007] The end of the positioning claw and the outer shell of the connector body form a notch of the second rotation groove, and the second rotation groove is interference-fitted with the claw rotation shaft.

[0008] The beneficial effects of this invention are as follows: the spacing between the notches of the first rotating groove on the hook is smaller than that of the hook's rotating shaft, preventing the flip cover from falling off the connector body; the second rotating groove on the retaining claw forms an interference fit with the claw's rotating shaft, thus allowing the flip cover to remain in place throughout the opening and closing process without requiring additional parts to position the rotating shaft, preventing the flip cover from freely moving and interfering with the connection during the process of tightening the bolts. Furthermore, the rotating shaft and flip cover are integrally formed, and the hook and retaining claw are also integrally formed with the connector body, reducing the number of parts and facilitating connector assembly.

[0009] Furthermore, the first rotation groove and the second rotation groove are coaxially arranged, and the hook rotation shaft and the claw rotation shaft are coaxially arranged.

[0010] The beneficial effect is that the injection molding of the outer shell and the flip cover of the connector body is facilitated.

[0011] Specifically, the inner diameter of the first rotating groove is the same as the diameter of the hook rotating shaft, and a rib is provided on at least one side of the notch of the first rotating groove.

[0012] The beneficial effect is that by arranging ribs on one side or both sides of the slot, the width of the first rotating slot can be made smaller than the diameter of the hook shaft, and the ribs can enhance the strength of the hook.

[0013] Furthermore, two ribs are provided at the notch of the first rotating groove, and the two ribs include a shell side rib and a hook side rib. The shell side rib is located on the outer shell of the connector body, and the hook side rib is located on the hook.

[0014] The beneficial effects are: the setting positions of the ribs on both sides of the notch of the first rotating groove are given, which is easy to implement, and the shell side ribs can strengthen the connection strength between the hook and the connector shell, and the hook side ribs can enhance the strength of the hook.

[0015] Specifically, the central angle corresponding to the first rotating groove is greater than 180°, and the size of the central angle needs to be sufficient to allow the hook shaft to enter the first rotating groove by forced installation.

[0016] The beneficial effect is that the central angle of the first rotating groove is greater than 180°, that is, the first rotating groove is an arc larger than a semicircle, and the width of the groove is less than its diameter, and therefore less than the diameter of the hook shaft. Because the hook is a plastic component with a certain degree of elasticity, after controlling the size of the central angle, the hook shaft can be installed into the first rotating groove by force.

[0017] Specifically, the second rotating groove is interference fit with the claw rotating shaft through an interference piece, and the interference piece is a claw side rib and / or a shell side rib, and the claw side rib is located on the inner wall of the second rotating groove, and the shell side rib is arranged at the position where the positioning claw is connected to the outer shell of the connector body, and is located on the outer shell of the connector body.

[0018] Its beneficial effects are: the interference fit between the second rotating groove and the claw shaft is achieved through the interference piece in the form of a convex rib, which is easy to implement, and the convex rib on the shell side can strengthen the connection strength between the stationary claw and the connector shell, and the convex rib on the claw side can enhance the strength of the stationary claw.

[0019] Furthermore, a groove is provided on the claw shaft, and as the claw shaft rotates in the stationary claw, the groove can be matched with the shell side rib or the claw side rib; when the groove is matched with the shell side rib, the flip cover is in a fully open position; when the groove is matched with the claw side rib, the flip cover is in a closed position.

[0020] Its beneficial effect is that when the flip cover is in the closed position and the fully open position, the shell side rib or the claw side rib enters the groove. Since the radial size of the rotating shaft at the groove position is reduced, there is no longer an interference force between the second groove and the claw rotating shaft. At this time, the retaining claw is no longer squeezed by the claw rotating shaft, which can avoid the creep of the retaining claw under long-term stress and ensure the retaining effect of the flip cover.

[0021] Alternatively, the distance between the two side portions of the inner wall of the second rotating groove located at the axis of the claw rotating shaft is smaller than the diameter of the claw rotating shaft, so as to achieve an interference fit between the second rotating groove and the claw rotating shaft.

[0022] Its beneficial effect is: proposing another way to achieve interference fit between the claw shaft and the stationary claw, which does not require setting ribs in the second rotating groove, but sets the shape of the inner wall of the second rotating groove so that it is not a regular arc shape. It is only necessary to make the distance between the two side parts of the inner wall of the second rotating groove located on the axis of the claw shaft less than the diameter of the claw shaft.

[0023] Furthermore, the outer shell of the connector body is provided with a shell side rib, which is located in the distribution range of the hook and the positioning claw, and the shell side rib is arranged opposite to the end of the hook and the positioning claw.

[0024] Its beneficial effect is that the side rib of the shell can cooperate with the hook and the positioning claw at the same time, so that the width of the first rotating groove on the hook is smaller than the diameter of the hook shaft, and at the same time, the interference fit between the second rotating groove and the claw shaft is achieved.

[0025] Furthermore, the outer surfaces of the hook and the parking claw are provided with raised reinforcing ribs.

[0026] The beneficial effect is that the strength of the hook and the retaining claw is enhanced, and the hook and the retaining claw are prevented from being cracked due to the rotation shaft squeezing the hook and the retaining claw when the flip cover is installed.

[0027] Furthermore, a protrusion is provided between the hook rotating shaft and the claw rotating shaft on the flip cover and at the outer end of the hook rotating shaft or the claw rotating shaft, and the protrusion protrudes from the inner surface of the flip cover.

[0028] The beneficial effect is that the height of the protruding block protruding from the inner surface of the flip cover can determine the amplitude of the flip cover being fully opened, so the fully opened position of the flip cover can be determined by setting the protruding height of the protruding block as needed.

[0029] Furthermore, a stop surface is provided on the protruding block, and when the flip cover is opened to the fully open position, the stop surface is in close contact with the side surface of the shell of the connector body.

[0030] The beneficial effect is that when the flip cover is opened, the stop surface contacts the outer shell of the connector body, thereby preventing the flip cover from opening at an excessively large angle.

[0031] Furthermore, the stop surface is a plane.

[0032] The beneficial effect is that the flat stop surface can better adhere to the outer shell of the connector body, making the flip cover in the open state more stable.

[0033] Furthermore, the flip cover has a closed position and a fully open position on the connector body, and the included angle between the flip cover in the fully open position and the closed position is an obtuse angle.

[0034] The beneficial effect is that the obtuse angle setting allows the fully opened flip cover to have a larger opening, providing a larger operating space and facilitating the operation of connector installation.

[0035] A positioning hole is provided on one side of the flip cover opposite to the rotating shaft.

[0036] The beneficial effect is that after the flip cover is closed, it is convenient for the bolt to pass through the positioning hole and the connector body and then be fixedly connected with another matching connector.

[0037] A flip connector comprises a connector body and a flip cover, wherein the connector body and the flip cover are connected via the flip cover retention structure.

[0038] The beneficial effect is that the flip cover can be stopped at any position within the opening range, achieving full-process parking. The beneficial effect of the utility model is that the utility model reduces the number of parts and simplifies the installation process through the integrated flip cover parking structure, and enables the flip cover to be stopped at any position within its allowable opening range, avoiding interference caused by the free movement of the flip cover during the operation of the connector.

[0039] The utility model relies on the interference fit between the stationary claw and the claw rotating shaft and utilizes the ribs on the hook to reduce the size of the side opening of the hook, thereby preventing the flip cover from falling off the connector body.

[0040] The groove provided on the claw rotating shaft of the utility model can cooperate with the convex rib on the positioning claw, so that when the flip cover is in the closed position and the fully open position, there is no force between the positioning claw and the claw rotating shaft, thereby avoiding creep of the positioning claw under long-term stress and ensuring the positioning effect of the positioning claw on the flip cover.

[0049] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention in any way.

[0050] Example 1: Refer to the attached Figure 1-3 As shown, a flip cover parking structure of a connector includes a hook 3 and a parking claw 4 arranged on the connector body 1 and a rotating shaft arranged on the flip cover 2.

[0051] Two hooks 3 are provided, and one retaining claw 4 is provided. The retaining claw 4 is located between the two hooks 3 and spaced apart from the hooks 3 on either side. The centerlines of the retaining claw 4 and the two hooks 3 are aligned. The hooks 3 and retaining claw 4 are both located on the same side of the connector body 1. The hook 3 has a circular arc-shaped receiving groove with one side open, which serves as a first rotation groove 501 for rotationally engaging with the rotating shaft on the flip cover 4. The retaining claw 4 has a circular arc-shaped receiving groove with one side open, which serves as a second rotation groove 502 for rotationally engaging with the rotating shaft on the flip cover 2. The first rotation groove 501 and the second rotation groove 502 on the hook 3 and retaining claw 4 are coaxially arranged, and the side openings of the three rotation grooves are oriented in the same direction.

[0052] like Figure 5 As shown, a rotating shaft is provided on one side of the flip cover 2, and the rotating shaft is divided into three sections by the raised block 14 on the flip cover 2, namely the hook rotating shaft 9 located at both ends and the claw rotating shaft 10 located in the middle. The hook rotating shaft 9 is rotationally matched with the hook 3 and is rotationally connected to the first rotating groove 501 of the hook 3. The claw rotating shaft 9 is rotationally matched with the stationary claw 4 and is rotationally connected to the second rotating groove 502 of the stationary claw 4.

[0053] For example Figure 3 、 4 As shown, the inner side of the opening of the first rotation groove 501 of the hook 3 is provided with ribs, including a housing-side rib 8 and a hook-side rib 6. The housing-side rib 8 is located on the outer shell of the connector body 1, and the hook-side rib 6 is located on the hook 3. The distance between the housing-side rib 8 and the hook-side rib 6 is smaller than the diameter of the hook shaft 9 on the flip cover 2. The inner diameter of the first rotation groove 501 is consistent with the diameter of the hook shaft 9. As a result, when the hook shaft 9 of the flip cover 2 rotates within the hook 3, the hook 3 is not subjected to the squeezing force of the hook shaft 9. The hook-side rib 6 and the housing-side rib 8 form a small opening, which can prevent the flip cover 2 from falling off the hook 3.

[0054] The second rotation groove 502 of the retaining claw 4 is provided with ribs on the inner side, including a housing-side rib 8 and a claw-side rib 7. The housing-side rib 8 is located on the outer shell of the connector body 1, while the claw-side rib 7 is located on the retaining claw 4. When the claw shaft 10 of the flip cover 2 is rotatably connected to the retaining claw 4, the claw shaft 10 forms an interference fit with the housing-side rib 8 and the claw-side rib 7. This interference fit between the claw shaft 10 and the retaining claw 4 ensures the flip cover 2 remains in position throughout its entire opening process from the closed position to the fully open position, allowing the flip cover 2 to remain stably in any position.

[0055] Furthermore, the outer surfaces of the hook 3 and the retaining claw 4 are provided with raised reinforcing ribs 13 to enhance the strength of the hook 3 and the retaining claw 4, so as to prevent the hook 3 and the retaining claw 4 from being squeezed by the rotating shaft when the flip cover 2 is installed, causing the hook 3 and the retaining claw 4 to crack.

[0056] Furthermore, a positioning hole 12 is provided on the flip cover 2 on one side relative to the rotating shaft. When the connector is connected, the flip cover 2 is closed, and the bolt passes through the positioning hole 12 and the connector body 1 to be fixedly connected to the other matching connector.

[0057] The hook 3 and the positioning claw 4 are integrally formed with the connector body 1, and the hook shaft 9, the claw shaft 10 and the protruding block are integrally formed with the flip cover 2. Therefore, the flip cover positioning structure described in the present invention does not require any additional parts and can achieve the positioning of the flip cover 2 on the connector body 1 throughout the entire opening and closing process.

[0058] Example 2: This example differs from Example 1 in that a groove 11 is provided on the claw shaft 10 on the flip cover 2. The length of the groove 11 extends along the axial direction of the claw shaft 10. The groove 11 is capable of accommodating the housing-side rib 8 and the claw-side rib 7. When the claw shaft 10 rotates within the stationary claw 4, the housing-side rib 8 and the claw-side rib 7 form an interference fit with the portion of the claw shaft 10 outside the groove 11. When the housing-side rib 8 or the claw-side rib 7 enters the groove 11, the radial dimension of the shaft at the location of the groove 11 is reduced, eliminating any interference force between the housing-side rib 8 and the claw-side rib 7 and the shaft. At this point, the stationary claw 4 is no longer squeezed by the claw shaft 10.

[0059] When the flip cover 2 is in the fully opened position, the groove 11 is matched with the convex rib 8 on the side of the shell. At this time, there is no force between the claw shaft 10 and the parking claw 4. At the same time, since there is no interference force between the hook 3 and the hook shaft 9, the hook 3 and the parking claw 4 are not squeezed by the shaft.

[0060] When the flip cover 2 is in the closed position, the groove 11 is matched with the convex rib 7 on the side of the claw. At this time, there is no force between the claw shaft 10 and the stationary claw 4. At the same time, since there is no interference force between the hook 3 and the hook shaft 9, the hook 3 and the stationary claw 4 are not squeezed by the shaft.

[0061] Therefore, the provision of the groove 11 on the claw shaft 10 can avoid creep of the hook 3 and the retaining claw 4 under long-term stress, thereby ensuring the retaining effect of the flip cover 2.

[0062] The fully open position of the flip cover 2 is determined by a raised block 14 on the flip cover 2. The raised block 14 protrudes from the inner surface of the flip cover 2. During the opening process, the raised block 14 abuts against the housing of the connector body 1, preventing further opening of the flip cover 2. At this point, the flip cover 2 is in the fully open position. Therefore, the protruding height of the raised block 14 determines the opening angle of the flip cover 2, that is, the fully open position of the flip cover 2.

[0063] Furthermore, a stop surface 15 is provided on the protruding block 14. When the flip cover 2 is opened, the stop surface 15 contacts the shell of the connector body 1, which can prevent the flip cover 2 from opening at too large an angle and can also better stabilize the flip cover 2 in the open state.

[0064] Furthermore, the included angle between the flip cover 2 in the fully open position and the closed position is an obtuse angle, so that the fully opened flip cover 2 can have a larger opening, providing a larger operating space and facilitating the operation of installing the connector.

[0065] Example 3: This example differs from Example 1 in that a rib is provided on one side of the first rotation slot 501. For example, a hook-side rib 6 is provided only at the end of the hook 3, or a housing-side rib 8 is provided only at the connection point between the hook 3 and the connector body 1. The rib structure provided on one side can reduce the width of the first rotation slot 501 and prevent the hook shaft 9 from falling off.

[0066] Example 4: This example differs from Example 1 in that the central angle of the first rotation groove 501 is greater than 180°, and the size of the central angle is sufficient to ensure that the hook shaft 9 can be inserted into the first rotation groove 501 by forced installation. This eliminates the need for ribs, reduces the width of the first rotation groove 501, and prevents the hook shaft 9 from falling out.

[0067] Example 5: The difference between this example and Example 1 is that the second rotating groove 502 is interference fit with the claw shaft 10 through an interference piece, and the interference piece is the claw side rib 7 or the shell side rib 8, that is, only the claw side rib 7 or only the shell side rib 8 is set, which can also clamp the claw shaft 10 and enable the flip cover 2 to be stationary throughout the entire process.

[0068] Example 6: The difference between this example and Example 1 is that: by setting the shape of the inner wall of the second rotating groove 502, it is no longer a regular arc shape, for example, it can be an ellipse or have multiple protrusions. As long as the distance between the two side parts of the inner wall of the second rotating groove 502 located on the axis of the claw shaft 10 is less than the diameter of the claw shaft 10, the interference fit between the second rotating groove 502 and the claw shaft 10 can be achieved.

[0069] Example 7: The difference between this example and Example 1 or 2 is that: Figure 3 As shown, the shell side rib 8 is located in the distribution range of the hook 3 and the positioning claw 4, and the shell side rib 8 is arranged opposite to the end of the hook 3 and the positioning claw 4, so that only one shell side rib 8 with a longer length needs to be set.

[0070] Embodiment 8: The difference between this embodiment and the above embodiments is that: both the hook 3 and the retaining claw 4 are provided in one piece, and the hook 3 and the retaining claw 4 have a larger length to ensure that the flip cover 2 still has good stability after being connected.

[0071] Example 9: Figure 7 As shown, a flip connector is a plug connector, comprising a connector body 1 and a flip cover 2. The flip cover 2 is rotatably provided on the back side of the plug end of the connector body 1, and the flip cover 2 is connected to the connector body 1 through the flip cover retention structure described in the above embodiments.

[0072] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Those skilled in the art should understand that the specific implementation methods of the present invention can be modified or replaced with equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
