Description

Technical Field

[0001] The utility model relates to the technical field of plug-in connection devices, in particular to a connection plate for installing plug-ins in a casing. Background Art

[0002] There are usually a bunch of plug-ins in the motor housing, and the motor will generate certain vibrations when running, which will affect the looseness of the plug-ins. Therefore, it is necessary to use a connecting plate to further fix these plug-ins. The plug-in connecting plate is also called a connector board, which is used to insert different plug-ins or connectors to achieve connection and communication between the motor and the control unit.

[0003] In the existing patent literature, there is a patent with publication number CN 207706588 U and the name of "A support structure for a connector". This patent mainly limits and fixes the plug-in wire of the connector through a first groove, a second groove, etc. However, the first groove, the second groove, etc. can only fix connectors of specific sizes and models, and its versatility and flexibility are poor. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a connecting plate for installing plug-ins in a casing. The connecting plate can constrain and fix the plug-in wires by arranging an elastic wire binding mechanism. Since the elastic wire binding mechanism adopts an open elastic clamping method for fixing, it can not only meet the fixation of plug-ins of different sizes and models, but also facilitate the installation and removal of the plug-ins.

[0005] In order to solve the above technical problems, the technical solution of the utility model is implemented as follows:

[0006] A connecting plate for installing plug-ins in a housing, comprising an annular plate body, guide seats arranged in a circumferential array at the edges of the front and rear sides of the annular plate body, elastic cable tie mechanisms installed on the guide seats and the front and rear sides of the annular plate body, a docking hole is provided through the center of the annular plate body, the plug-in comprises a plug-in wire and a plug, two plug-ins are connected from the front and rear sides of the annular plate body respectively, the plug-in wires of the two plug-ins are restrained and fixed by the elastic cable tie mechanism, and the plugs of the two plug-ins are connected in the docking hole;

[0007] The elastic wire harness mechanism includes two half-wire harness pressure seats, which together form a complete wire harness pressure seat. Each half-wire harness pressure seat is slidably connected to a guide rod, which is fixed to a guide seat or an annular plate. The guide rod is equipped with a spring that pushes the half-wire harness pressure seat to press the plug wire.

[0008] With this solution, the connecting plate is used to fix the plug-in in the motor casing to reduce the incidence of loosening of the plug-in due to the resonance of the motor. The connecting plate can constrain and fix the plug-in wires by arranging an elastic wire harness mechanism. Since the elastic wire harness mechanism adopts two half-wire harness pressure seats to clamp and fix the plug-in wires, and the two half-wire harness pressure seats are clamped by spring push, it can not only meet the fixation of plug-ins of different sizes and models, but also has stronger versatility. Moreover, the space between the two half-wire harness pressure seats can be opened, which is convenient for installing and removing the plug-in wires.

[0009] As a preferred embodiment of the connecting plate for installing the plug-in in the housing, the elastic cable tie mechanism also includes a pull ring, the pull ring is fixedly connected to the half cable tie pressure seat, a nut is fixed on the pull ring, a screw rod passing through the pull ring is assembled in the nut, and a through hole matching with the screw rod is opened on the pull ring;

[0010] On the two half-beam pressure seats, the screw on one of the half-beam pressure seats can be matched with the through hole on the other half-beam pressure seat, so as to complete the merging of the two half-beam pressure seats;

[0011] A pull hole is provided at the center of the pull ring.

[0012] This solution is adopted to facilitate the installation and disassembly of the plug-in wire. A pull ring is provided. When the plug-in wire needs to be installed or disassembled, it is only necessary to pull the pull ring on one of the half-wire pressure seats, so that there is a certain height difference between the two half-wire pressure seats, and the two half-wire pressure seats can be "opened", thereby facilitating the installation or disassembly of the plug-in wire. After the plug-in wire is installed, the two half-wire pressure seats can be merged by rotating the screw so that it cooperates with the through hole, which can improve the stability of the entire elastic wire harness mechanism when clamping the plug-in wire.

[0013] As a preferred embodiment of the connecting plate for installing plug-ins in a housing, the guide seat and the front and rear sides of the annular plate body are also provided with linear limiting grooves located at the location of the elastic wire harness mechanism;

[0014] The linear limiting groove is a linear triangular groove.

[0015] By adopting this solution, in order to further improve the reliability of the pin being clamped, a linear limiting groove is provided. When the wire insertion elastic cable tie mechanism is clamped, the linear limiting groove can limit the bottom of the wire insertion, thereby further improving the clamping effect.

[0016] As a preferred embodiment of a connection plate for installing plug-ins in a housing, the contact surface between the half-wire pressing seat and the plug-in wire is an arc surface;

[0017] An anti-slip portion is arranged on the contact surface between the half-wire pressing seat and the plug-in wire, wherein the anti-slip portion is an anti-slip pattern.

[0018] This solution is adopted to increase the friction force when the half-wire pressure seat contacts the plug-in wire, and an anti-slip portion is provided on the arc surface where the two contact, so as to increase the friction force when in contact, thereby improving the stability of clamping.

[0019] As a preferred embodiment of a connecting plate for installing a plug-in in a casing, an annular docking cavity is provided on the inner wall of the docking hole, and the plug is correspondingly located at the location of the annular docking cavity.

[0020] With this solution, since the plug is larger than the plug wire, an annular docking cavity is provided on the inner wall of the docking hole to expand the space where the plug is located, thereby accommodating a greater number of plugs.

[0021] As a preferred embodiment of a connecting plate for installing an internal plug-in of a casing, there are positioning seats in a circular array at the edges of the front and rear sides of the annular plate body. Screw holes are opened through the positioning seats, and fastening screws are installed in the screw holes. The screw heads of the fastening screws can contact the inner wall of the motor casing.

[0022] By adopting this solution, in order to fix the annular plate body in the motor housing, the top screws are rotated and tightened, and the screw heads of the top screws are used in various directions to contact the inner wall of the motor housing, thereby fixing the annular plate body.

[0023] After adopting the above technical solution, the beneficial effects of the utility model are:

[0024] 1. The connecting plate is used to fix the plug-in in the motor casing to reduce the incidence of loosening of the plug-in due to the resonance of the motor. The connecting plate can constrain and fix the plug-in wires by arranging an elastic wire harness mechanism. Since the elastic wire harness mechanism adopts two half-wire harness pressure seats to clamp and fix the plug-in wires, and the two half-wire harness pressure seats are clamped by spring push, it can not only meet the fixation of plug-ins of different sizes and models, but also has stronger versatility. Moreover, the two half-wire harness pressure seats can be opened, which is convenient for installing and removing the plug-in wires.

[0025] 2. In order to facilitate the installation and disassembly of the plug-in wire, a pull ring is provided. When the plug-in wire needs to be installed or disassembled, it is only necessary to pull the pull ring on one of the half-wire pressure seats, so that there is a certain height difference between the two half-wire pressure seats, and the two half-wire pressure seats can be "opened", thereby facilitating the installation or disassembly of the plug-in wire; after the plug-in wire is installed, the two half-wire pressure seats can be merged by rotating the screw so that it cooperates with the through hole, which can improve the stability of the entire elastic wire harness mechanism when clamping the plug-in wire.

[0026] 3. In order to further improve the reliability of the pin being clamped, a linear limit groove is set. When the wire plug elastic cable tie mechanism is clamped, the linear limit groove can limit the bottom of the plug wire, thereby further improving the clamping effect.

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] The elastic wire harness mechanism 3 includes two half-wire harness pressure seats 301, which together constitute a complete wire harness pressure seat. Each half-wire harness pressure seat 301 is slidably connected to a guide rod 302, and the guide rod 302 is fixed on the guide seat 2 or the annular plate body 1. The guide rod 302 is sleeved with a spring 303 that pushes the half-wire harness pressure seat to press the plug wire 5.

[0040] The connecting plate is capable of restraining and fixing the plug-in wire 5 of the plug-in by setting an elastic wire binding mechanism 3. Since the elastic wire binding mechanism 3 adopts two half-wire binding seats 301 to clamp and fix the plug-in wire 5, and the two half-wire binding seats 301 are clamped by springs 303, it can not only meet the fixation of plug-ins of different sizes and models, but also has stronger versatility. Moreover, the space between the two half-wire binding seats can be opened, which is convenient for installing and removing the plug-in wire 5.

[0041] like Figures 5 to 7 As shown, the elastic cable tie mechanism 3 also includes a pull ring 304, which is fixedly connected to the half cable tie pressure seat, a nut 305 is fixed on the pull ring 304, a screw 306 passing through the pull ring 304 is assembled in the nut 305, and a through hole 307 matching with the screw 306 is opened on the pull ring 304;

[0042] On the two half-beam press seats 301, the screw 306 on one half-beam press seat 301 can be matched with the through hole 307 on the other half-beam press seat 301, so as to complete the merging of the two half-beam press seats 301;

[0043] A pull hole 308 is defined at the center of the pull ring 304 .

[0044] In order to facilitate the installation and removal of the plug wire 5, a pull ring 304 is provided. When the plug wire 5 needs to be installed or removed, it is only necessary to pull the pull ring 304 on one of the half-wire pressure seats, so that there is a certain height difference between the two half-wire pressure seats 301, and the two half-wire pressure seats 301 can be "opened", thereby facilitating the installation or removal of the plug wire 5; after the plug wire 5 is installed, the screw 306 is rotated to make it cooperate with the through hole 307, so that the two half-wire pressure seats 301 can be merged, which can improve the stability of the entire elastic wire harness mechanism 3 when clamping the plug wire 5.

[0045] like Figure 3 As shown, the guide seat 2 and the front and rear sides of the annular plate body 1 are also provided with linear limiting grooves 7 located where the elastic wire harness mechanism 3 is located;

[0046] The linear limiting groove 7 is a linear triangular groove.

[0049] An anti-slip portion is provided on the contact surface between the half-wire pressing seat and the plug wire 5, wherein the anti-slip portion is an anti-slip pattern.

[0050] In order to increase the friction force when the half-wire pressing seat contacts the plug wire 5, an anti-slip portion is provided on the arc surface where the two contact, so as to increase the friction force during contact and thus improve the stability of clamping.

[0051] like Figure 8 As shown, an annular docking cavity 8 is provided on the inner wall of the docking hole 4 , and the plug 6 is correspondingly located at the location of the annular docking cavity 8 .

[0052] Since the plug 6 is larger in size than the plug wire 5 , an annular docking cavity 8 is provided on the inner wall of the docking hole 4 to expand the space where the plug 6 is located, thereby accommodating a greater number of plugs 6 .

[0053] like Figure 3 to Figure 4 As shown, there are positioning seats 9 in a circumferential array at the edges of the front and rear sides of the annular plate body 1. Screw holes 10 are penetrated through the positioning seats 9. Fastening screws 11 are installed in the screw holes 10. The screw heads of the fastening screws 11 can contact the inner wall of the motor housing.

[0054] In order to fix the annular plate body 1 in the motor housing, the top screw 11 is rotated and tightened, and the screw heads of the top screw 11 in various directions are used to abut against the inner wall of the motor housing, thereby fixing the annular plate body 1.

[0055] The working principle of this utility model:

[0056] First, by rotating and tightening the top screw 11, the screw heads of the top screw 11 in various directions are used to abut against the inner wall of the motor housing, so as to fix the annular plate body 1 in the motor housing.

[0057] Then, the control unit plug-in and the motor plug-in are connected from the front and rear sides of the annular plate body 1 respectively, and the plug wires 5 of the two plug-ins are constrained and fixed by the elastic wire harness mechanism 3, and the plugs 6 of the two plug-ins are connected in the docking hole 4. In specific operation, it is only necessary to pull the pull ring 304 on one of the half-wire harness pressure seats so that there is a certain height difference between the two half-wire harness pressure seats 301, and then the two half-wire harness pressure seats 301 can be "opened", so that the plug wire 5 can be installed under the two half-wire harness pressure seats 301, and then, by rotating the screw 306 so that it cooperates with the through hole 307, the two half-wire harness pressure seats 301 can be merged, which can improve the stability of the entire elastic wire harness mechanism 3 when clamping the plug wire 5.

[0058] In this way, since the plug-in wire 5 is clamped and fixed by the elastic wire binding mechanism 3, the incidence of the plug-in loosening due to the resonance of the motor is reduced.

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
