Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a connector with an anti-slipping assisting mechanism. Background Art

[0002] With the widespread application of connectors in many industries, people have put forward higher and higher requirements on the safety, electrical performance and operational convenience of connectors.

[0003] In order to ensure that the connector has lower resistance, better electrical connection stability and a higher level of waterproof performance, it is usually necessary to apply a large installation force to ensure the assembly between the connector plug and the socket. In order to meet the requirement that the connector requires a large installation force to achieve the assembly of the plug and the socket, it is usually necessary to set a rotatable power-assisting mechanism on the connector in a snap-on manner. In this way, you only need to operate the power-assisting mechanism to rotate it relative to the connector housing, and you can use a relatively small force to complete the assembly between the plug and the socket.

[0004] However, the existing connector structure has shortcomings: since the power-assisting mechanism is rotatably arranged on the connector housing in a snap-fit ​​manner, the power-assisting mechanism is very easy to detach from the connector housing after being rotated by force during the rotation process, that is, there is a risk of the power-assisting mechanism detaching.

[0014] A first buckle portion is provided on the connector housing and is buckled with the second anti-slip structure to realize the rotation of the power-assisting mechanism relative to the connector housing; wherein, after the second anti-slip structure and the first buckle portion are buckled with each other, an initial assembly position is formed to realize the initial assembly state of the power-assisting mechanism and the connector housing;

[0015] The stopper is arranged on the connector housing and prevents the assisting mechanism from returning to the initial assembly position during its rotation stroke after rotation.

[0016] Further improved, in the connector with the anti-slip assist mechanism, the first anti-slip structure comprises:

[0017] The lower end portion is a column formed on the connector housing;

[0018] An upper end portion, located above the lower end portion and formed on the cylindrical surface of the lower end portion;

[0019] The second anti-slip structure comprises:

[0021] The upper opening is connected with the lower opening and fits in with the upper end; wherein the aperture size of the upper opening is smaller than the aperture size of the lower opening.

[0022] As an improvement, in the connector with the anti-slip assist mechanism, the resisting portion is located outside the rotation stroke of the assist mechanism and at the front end of the initial assembly position.

[0023] Further, in the connector with the anti-slip assist mechanism, the resisting portion is a protruding structure protruding from the connector housing, located on the assist mechanism and provided with a resisting mating portion on the outer periphery of the second anti-slip structure; wherein:

[0024] The resisting portion comprises:

[0025] The rotation guide surface is an arc-shaped surface and is located below the blocking portion;

[0026] A resisting surface, located on the side wall of the resisting portion;

[0027] The resisting and matching portion comprises:

[0028] A rotational matching surface cooperates with the rotational guide surface of the resisting portion so that the rotational matching surface rotates along the direction formed by the rotational guide surface;

[0029] The resisting matching surface is located on the side wall of the resisting matching portion and cooperates with the resisting surface of the resisting portion to prevent the rotating matching surface from rotating in the reverse direction after rotation.

[0037] Secondly, by making the anti-slip mechanism include a first anti-slip structure located on the connector shell and a second anti-slip structure located on the power-assisting mechanism and cooperating with the first anti-slip structure, the first anti-slip structure includes a first snap-fit ​​portion and a blocking portion located outside the rotation stroke of the power-assisting mechanism and at the front end of the initial assembly position. The first snap-fit ​​portion and the second anti-slip structure snap-fit ​​to form an initial assembly position in which the power-assisting mechanism and the connector shell reach an initial assembly state. The blocking portion is provided on the connector shell and prevents the power-assisting mechanism from resetting to the initial assembly position during its rotation stroke after rotation, thereby ensuring that as long as the power-assisting mechanism enters the rotation stroke through the blocking portion, the power-assisting mechanism cannot return to the initial assembly position due to the blocking action of the blocking portion, and thus the power-assisting mechanism cannot detach from the connector shell.

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0046] This embodiment provides a connector with an anti-escape assistance mechanism. Figures 1 to 6 As shown, the connector with an anti-slipping assist mechanism of this embodiment includes a connector housing 1, an assist mechanism 2 and an anti-slipping mechanism. The assist mechanism 2 is rotatably arranged on the connector housing 1 by a snap-fit ​​manner. The assist mechanism 2 and the connector housing 1 are assembled and matched with each other to form an initial assembly position I in which the two reach an initial assembly state; the anti-slipping mechanism is configured to limit the rotational stroke of the assist mechanism 2 to prevent the assist mechanism 2 from resetting to the initial assembly position I in its rotational stroke S after rotation.

[0047] See also Figure 2 and Figure 3As shown, the anti-slip mechanism of this embodiment includes a first anti-slip structure and a second anti-slip structure 21, the first anti-slip structure is arranged on the connector housing 1, and the second anti-slip structure 21 is arranged on the power-assisting mechanism 2 and cooperates with the first anti-slip structure to limit the rotation stroke of the power-assisting mechanism 2 to prevent the power-assisting mechanism from escaping from the connector housing 1. For example, the first anti-slip structure includes a first snap-on portion 11 and a stopper portion 12, the first snap-on portion 11 is arranged on the connector housing 1 and snap-fits with the second anti-slip structure 21 to realize the rotation of the power-assisting mechanism 2 relative to the connector housing 1; wherein the second anti-slip structure 21 snap-fits with the first snap-on portion 11 to form an initial assembly position I for realizing the initial assembly state of the power-assisting mechanism 2 and the connector housing 1; the stopper portion 12 is arranged on the connector housing 1 and prevents the power-assisting mechanism 2 from resetting to the initial assembly position I in its rotation stroke S after rotation by resisting the power-assisting mechanism 2.

[0048] As a way to implement the second anti-slip structure, in this embodiment, the power assist mechanism 2 may have a rotating arm 21 , and the second anti-slip structure 21 may be disposed on the rotating arm 21 .

[0049] It should be noted that see Figure 7 As shown, in this embodiment, the rotation stroke S of the power-assisting mechanism 2 includes an initial rotation position A, an end rotation position B and a movement stroke S0, wherein the initial rotation position A is close to the initial assembly position I of the power-assisting mechanism 2; the end rotation position B is away from the initial assembly position I of the power-assisting mechanism 2; the movement stroke S0 is located between the initial rotation position A and the end rotation position B; wherein the direction of the axis L1 of the power-assisting mechanism 2 at the initial assembly position I is perpendicular to the direction of the axis L2 of the power-assisting mechanism 2 at the initial rotation position A.

[0050] As a way to realize the snap-fitting of the first snap-fitting portion and the second anti-slipping structure, in this embodiment, the first snap-fitting portion 11 includes a lower end portion 111 and an upper end portion 112, the lower end portion 111 is a column formed on the connector housing 1, and the upper end portion 112 is located above the lower end portion 111 and is formed on the column surface of the lower end portion 111; the second anti-slipping structure 21 includes a lower opening 211 and an upper opening 212, the lower opening 211 is snapped into the lower end portion 111 of the first snap-fitting portion 11 to realize the rotational fit between the lower end portion and the lower opening; the upper opening 212 is connected to the lower opening 211 and is snapped into the upper end portion 112 of the first snap-fitting portion 11; wherein the aperture size of the upper opening 212 is smaller than the aperture size of the lower opening 211. By setting the structure of the first snap-on part and the second anti-slip structure in this way, when the power-assisting mechanism needs to be transferred to the connector housing 1, the lower end of the first snap-on part can correspond to the lower opening of the second anti-slip structure, and the upper end of the first snap-on part can correspond to the upper opening of the second anti-slip structure, and then the first snap-on part and the second anti-slip structure can be snapped, thereby realizing the snap-on fit of the first snap-on part and the second anti-slip structure, and the first snap-on part and the second anti-slip structure are in the initial assembly position I at this time. In this way, not only the first snap-on part is snapped into the hole of the second anti-slip structure, but also the second anti-slip structure can be rotated relative to the hole of the first snap-on part of the connector housing. Since the second anti-slip structure and the first snap-on part of the connector housing correspond to each other only in the initial assembly position I, the second anti-slip structure can be removed from the connector housing through operation. Once the second anti-slip structure is rotated based on the initial assembly position I, the upper opening and lower opening of the second anti-slip structure cannot correspond to the upper end and lower end of the first snap-fit ​​part of the connector shell. Also, due to the resisting effect of the resisting part on the reverse movement of the power-assisting mechanism, the second anti-slip structure cannot be detached from the connector shell.

[0051] As a preferred location of the resisting portion on the connector housing, in this embodiment, the resisting portion 12 is located outside the rotation stroke S of the power-assisting mechanism 2 and at the front end of the initial assembly position I. In this way, when the power-assisting mechanism rotates toward the initial assembly position I, the power-assisting mechanism cannot return to the original initial assembly position I due to the resisting effect of the resisting portion on the power-assisting mechanism, and the power-assisting mechanism cannot be disengaged from the first buckle portion of the connector housing.

[0052] As a way to achieve the resistance of the resisting portion to the assisting mechanism, in this embodiment, the resisting portion 12 is a protruding structure protruding from the connector housing 1, located on the assisting mechanism 2 and provided with a resisting mating portion 22 on the outer periphery of the second anti-slip structure 21. The resisting portion 12 includes a rotation guide surface 121 and a resisting surface 122, the rotation guide surface 121 is an arc-shaped surface and is located below the resisting portion 12, and the resisting surface 122 is located on the side wall of the resisting portion 12; the resisting mating portion 22 includes a rotation mating surface 221 and a resisting mating surface 222, the rotation mating surface 221 cooperates with the rotation guide surface 121 of the resisting portion 12 to make the rotation mating surface 221 rotate along the direction formed by the rotation guide surface 121 (see Figure 1 The resisting mating surface 222 is located on the side wall of the resisting mating portion 22 and cooperates with the resisting surface 122 of the resisting portion 12 to prevent the rotating mating surface 221 from rotating in the reverse direction (see Figure 1 In this embodiment, the resisting portion 12 is a convex ridge structure. Once the rotating mating surface 221 of the resisting mating portion 22 rotates along the direction of the rotating guide surface 121 and the rotating mating surface 221 is completely rotated, even if force is applied to the assisting mechanism 2 again, the resisting mating surface 222 of the resisting mating portion 22 cooperates with the resisting surface 122 of the resisting portion 12 to ensure that the entire resisting mating portion 22 will not rotate in the reverse direction (see Figure 1 In the figure, it is counterclockwise rotation), that is, the power assist mechanism cannot generate a rotational rotation due to being resisted by the resisting part.

[0053] The following combination Figures 1 to 7 , the principle of the anti-escape of the power-assisting mechanism of the connector with the anti-escape power-assisting mechanism in this embodiment is explained:

[0054] When the power-assist mechanism needs to be assembled to the connector housing, the lower end of the first buckle portion corresponds to the lower opening of the second anti-slip structure, the upper end of the first buckle portion corresponds to the upper opening of the second anti-slip structure, and then the first buckle portion and the second anti-slip structure are buckled to achieve the buckle fit between the first buckle portion and the second anti-slip structure. At this time, the first buckle portion and the second anti-slip structure are in the initial assembly position I; the first buckle portion and the second anti-slip structure are in the initial assembly position I. Figure 3 As shown;

[0055] On the basis that the first buckle portion and the second anti-detachment structure are in the initial assembly position I, a pulling force is applied to the power-assisting mechanism, so that the power-assisting mechanism rotates and enters the initial rotation position A of the rotation stroke of the power-assisting mechanism through the resisting portion. At this time, the upper opening of the second anti-detachment structure no longer corresponds to the upper end portion of the first buckle portion. Even if the power-assisting mechanism is rotated from the initial rotation position A toward the initial assembly position I, the power-assisting mechanism cannot continue to rotate due to the resistance of the resisting portion to the power-assisting mechanism, and the upper opening of the second anti-detachment structure cannot correspond to the upper end portion of the first buckle portion again. At this time, the power-assisting mechanism cannot be detached from the connector housing; wherein, the state of the connector power-assisting mechanism in the initial rotation position A refers to Figure 4 As shown;

[0056] Of course, during the whole process of the assist mechanism rotating from the initial position A, through the movement stroke S0, and finally rotating to the rotation end position B, the upper opening of the second anti-detachment structure and the upper end of the first buckle portion will never appear in the state of mutual correspondence at the initial assembly position I, and the resisting portion resists the assist mechanism, thereby ensuring that the assist mechanism will not fall out of the connector housing no matter how it rotates during its rotation stroke. Figure 5 As shown, the state of the power assist mechanism of the connector when it is in the rotation end position B is shown in FIG. Figure 6 shown.

[0057] Although the preferred embodiments of the present invention are described in detail above, it should be clearly understood that the present invention may be modified and varied by those skilled in the art. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
