Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, in particular to a connector with adjustable direction. Background Art

[0002] The connector consists of an angle-adjustable socket component and a flange component, and is widely used on the housing of servo motors in the field of industrial robot arms to achieve the transmission of power and encoder signals.

[0003] The motion trajectory and usage scenarios of existing robotic arms are relatively complex, and the requirements for connectors and cable assemblies on the casing are relatively stringent. The cable output direction is also changeable and not fixed, which requires the use of connectors at various angles. The maintenance and on-site debugging of multiple materials and the selection of connectors are not conducive to industrial production.

[0004] Currently, the insertion direction of the connector installed on the casing is generally fixed. However, when the robotic arm performs complex, multi-dimensional movements, it will drive the servo motor and the connector on it to move synchronously. Therefore, the existing connector cannot meet the requirements of synchronous direction adjustment with the servo motor, which will lead to messy wires, cross-entanglement or cable breakage.

[0005] In the prior art, in order to deal with the problem of servo motors rotating at any time, a common solution is to use a variety of connectors at various angles. However, the maintenance of multiple materials and the selection of connectors for on-site debugging are not conducive to industrial production. Utility Model Content

[0006] To address the aforementioned issues, the present invention proposes a direction-adjustable connector. By integrating the concave-convex structure, the socket component, the flange housing, the elastic member, and the compression member, the connector can be rotated in an adjustable direction in the circumferential direction. This allows the connector to adapt to various device configurations. Furthermore, the adjustable structure is simple and requires fewer parts, making direction adjustment simple and easy.

[0007] The utility model is realized by the following technical solutions:

[0008] A direction-adjustable connector comprises a socket component and a flange housing that can be snap-connected, wherein the bottom of the inner cavity of the socket component is provided with a downwardly extending protrusion, and the flange housing is provided with an accommodating cavity capable of accommodating the protrusion, and the inner wall of the accommodating cavity is provided with a stop step along the circumference;

[0009] The socket component and the flange housing are fastened together at a location where an adjustable direction structure is provided. The adjustable direction structure includes an elastic member, a pressing member, and a concave-convex structure I and a concave-convex structure II having crests and troughs arranged along the circumferences of the socket component and the flange housing, respectively. The pressing member is installed in the accommodating cavity and connected to the protruding portion. The elastic member is provided between the protruding portion and the inner wall of the accommodating cavity in the circumferential direction and is limited in the axial direction by the stop surface of the stop step cooperating with the pressing member.

[0010] Through the cooperation among the concave-convex structure, the socket component, the flange housing, the elastic component and the pressing component, when a torque force is applied to the socket component, the connector can be rotated in an adjustable direction in the circumferential direction.

[0011] Furthermore, the elastic member is an annular opening structure with convex and concave shapes along the circumference.

[0012] Furthermore, the elastic member is an open wave spring.

[0013] Furthermore, the elastic member is a conical spring.

[0014] Furthermore, the pressing member is a nut, which is threadedly connected to the protruding portion.

[0015] Furthermore, the socket component includes a first socket shell, a second socket shell and an insulator component, the first socket shell is snap-fitted to the second socket shell and fixed by a top screw, the insulator component is located in the inner cavity after snapping and is connected to the second socket shell, and the protruding portion is connected to the bottom end of the second socket shell.

[0016] Furthermore, the concave-convex structure is a flat tooth, the concave-convex structure I is circumferentially distributed on the end surface of the second socket housing, and the concave-convex structure II is circumferentially distributed on the end surface of the accommodating cavity.

[0017] Furthermore, the concave-convex structure is a conical tooth, the concave-convex structure I is distributed obliquely along the circumference on the outer edge of the protruding part, and the concave-convex structure II is distributed obliquely along the circumference on the inner wall of the upper end of the accommodating cavity.

[0018] Furthermore, sealing rings are provided between the accommodating cavity and the protruding portion, and between the accommodating cavity and the pressing member.

[0019] Furthermore, the sealing ring at the bottom is arranged in a groove surrounded by the flange shell and the pressing member.

[0020] The beneficial effects of the present invention are:

[0021] (1) The present invention utilizes a concave-convex structure to adjust the direction. A certain number of concave-convex structures are provided on the end face of the second socket housing and the end face of the flange housing. The concave-convex structure is used to control the direction-adjustable connector to rotate to the target position. Adjustment is achieved through the adjustable direction structure. This allows a connector to adapt to various device scenarios. In addition, the adjustable direction structure is simple and has fewer parts, making it easy to adjust the direction.

[0022] (2) Compared with the prior art which uses an open spring washer as an elastic member, the elastic member in the present invention is an annular open structure or a conical spring with undulating circumference, which can provide a stable elastic force and a wider range of axial displacement of the elastic force.

[0023] (3) When adjusting the direction of the present invention, the flange shell is fixed with a tool, and a torque force is applied to the socket component along the circumferential direction. The torque force is transmitted to the two concave-convex structures. The two concave-convex structures are in a separated state, so that the socket component rotates to the target angle. During the rotation of the socket component, the elastic member is continuously compressed in the axial direction, so that the socket component and the flange shell are separated in the axial direction. When the socket component rotates to the target angle, the elastic member rebounds in the axial direction, so that the two concave-convex structures are engaged to ensure that the connector is at the target angle. That is, through the cooperation between the second socket shell, the flange shell, the elastic member and the pressing member, when a torque force is applied to the socket component, the connector can be rotated in an adjustable direction in the circumferential direction.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that in the description of the present invention, unless otherwise specified, the meaning of "multiple" is two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0033] like Figure 1 、 Figure 2 As shown, the present invention provides a direction-adjustable connector, comprising a socket component 1 and a flange housing 2 that can be snap-fitted together. The socket component comprises a first socket housing 11, a second socket housing 12, and an insulator component 13. The first socket housing 11 is snap-fitted to one end of the second socket housing 12 and fixed by a top screw. The insulator component 13 is located in the inner cavity after snapping together and is connected to the second socket housing 12. The extension portion 6 is connected to the bottom end of the second socket housing 12. The specific structure of the connector is described in detail below.

[0034] Please refer to Figure 5 and Figure 7, a downwardly extending protruding portion 6 is provided at the bottom of the inner cavity of the second socket shell 12, and a accommodating cavity 21 capable of accommodating the protruding portion 6 is provided inside the flange shell 2, and a stopping step 211 is provided on the inner wall of the accommodating cavity 21 along the circumferential direction; an adjustable direction structure is also provided at the fastening point between the second socket shell 12 and the flange shell 2, and the adjustable direction structure includes an elastic member 4, a pressing member, and a plurality of concave-convex structures I 101 and concave-convex structures II 201 with crests and troughs arranged along the circumference of the second socket shell 12 and the flange shell 2 respectively; the pressing member is installed in the accommodating cavity 21 and is detachably connected to the protruding portion 6, and the elastic member 4 acts between the protruding portion 6 and the inner wall of the accommodating cavity 21 in the annular direction, and is limited in the axial direction by cooperating with the pressing member through the stopping surface of the stopping step 211; through the concave-convex structure I 101 and the concave-convex structure II 201. The cooperation between the second socket housing 12, the flange housing 2, the elastic member 4 and the pressing member can realize the adjustable rotation of the connector in the circumferential direction when a torque force is applied to the socket component.

[0035] It should be noted that the elastic member 4 needs to be a component capable of axial compression, and the elastic member 4 is a ring-shaped opening structure with convex and conical circumference or a conical spring. This structure can provide a stable elastic force, and the axial displacement range of the elastic force is wider. Specifically, when the elastic member 4 is a ring-shaped opening structure with convex and conical circumference, please refer to Figure 3 , the elastic member 4 is an open wave spring.

[0036] Specifically, the pressing member is a nut 3 with an internal thread, the outer peripheral surface of the protruding portion 6 is provided with an external thread, and the nut 3 is threadedly connected to the protruding portion 6.

[0037] The method for adjusting the direction using the adjustable directional structure is as follows: the flange housing 2 is fixed to the mounting panel using fasteners, and a torque force is applied to the socket component 1 along the circumferential direction by manually rotating the socket component 1. The torque force is transmitted to the concave-convex structure, and the two concave-convex structures are separated, allowing the socket component 1 to rotate to the target angle. During the rotation of the socket component 1, the elastic member 4 is continuously compressed axially, causing the socket component 1 and the flange housing 2 to move axially apart. When the socket component 1 rotates to the target angle, the elastic member 4 rebounds axially, causing the two concave-convex structures to engage, ensuring that the connector is at the target angle. In other words, through the cooperation between the second socket housing 12, the flange housing 2, the elastic member 3, and the compression member, when a torque force is applied to the socket component 1, the connector can be rotated in an adjustable circumferential direction.

[0038] The specific location of the concave-convex structure can be set according to the specific situation, as long as the relative rotation between the second socket housing 12 and the flange housing 2 can be achieved. For example, please refer to Figure 2The concave-convex structure can be set as a flat tooth structure, the concave-convex structure I 101 is distributed along the circumference at the end surface of the second socket housing 12, and the concave-convex structure II 201 is distributed along the circumference at the end surface of the accommodating cavity 21. The concave-convex structure can also be set as a conical tooth, please refer to Figure 1 At this time, the concave-convex structure I 101 is distributed along the circumference and tilted on the outer edge of the protruding portion 12, and the concave-convex structure II 201 is distributed along the circumference and tilted on the inner wall of the upper end of the accommodating cavity 21.

[0039] Please refer to Figure 4 , a sealing ring 5 is provided between the accommodating cavity 21 and the protruding portion 6, and between the accommodating cavity 21 and the pressing member. The sealing ring 5 located at the upper part makes the flange housing 2 and the second socket housing 12 cooperate circumferentially, generating radial extrusion of the sealing ring 5, thereby making the second socket housing 12 and the flange housing 2 fit tightly on the circumference, so as to achieve a sealing effect between the flange housing 2 and the second socket housing 12; please refer to Figure 6 The bottom sealing ring 5 is located within a groove formed by the limiting groove I203 on the inner wall of the flange housing 2 and the limiting groove II 301 on the outer circumference of the compression member. Both limiting groove I 203 and limiting groove II 301 have axial extrusion surfaces for axially extruding the sealing ring 5 and radial extrusion surfaces for radially extruding the sealing ring 5. The cross-section of the groove is a U-shaped groove structure with its opening facing away from the engagement end. When the connector and the mounting panel are circumferentially engaged, the sealing ring 5 positioned within the groove is simultaneously extruded axially and radially by the flange housing 2 and the compression member, thereby achieving a sealing effect. When the connector is adjusted in direction, the flange housing 2 and the second socket housing 12 move axially away from each other. When the second socket housing 12 is lifted upward with the compression member, the axial extrusion surface of limiting groove I 203 can axially limit the position of the sealing ring 5, preventing it from being affected by the axial movement of the socket component 1.
