[0047] Reference below Figure 1-Figure 5 The plug device 100 according to the embodiment of the utility model is described. The plug device 100 is suitable for plugging with the adapter 200. The adapter 200 can be a steering gear, a clutch, etc. This application takes the adapter 200 as an example of a steering gear. The steering gear is an important part of the automobile suspension system. The performance of the steering gear plays an important role in the control and safety of the vehicle. In order to ensure the safe driving of the vehicle, it is necessary to conduct comprehensive functional tests on the steering gear, such as: steering gear assembly running-in test, steering gear sensor characteristic detection, steering gear comprehensive performance detection, etc.

[0048] like Figure 1-Figure 2As shown, according to a plug device 100 of an embodiment of the utility model, the plug device 100 is suitable for plugging and matching with the adapter 200, including: a shell 1, the shell 1 defines an installation space 11, and along a first direction, one end of the shell 1 is formed with a plug interface 12 connected to the installation space 11; an electrode 2, the electrode 2 is fixed in the installation space 11 and is arranged corresponding to the plug interface 12, and the electrode 2 extends along the first direction; a locking member 3, the locking member 3 is movably provided on the shell 1, and the locking member 3 has a locking position and an unlocking position relative to the shell 1, when the locking member 3 is in the locked position, the locking member 3 is suitable for locking with the adapter 200, and when the locking member 3 is in the unlocking position, the locking member 3 is suitable for unlocking with the adapter 200.

[0049] The plug device 100 includes a housing 1, an electrode 2 and a locking member 3. The housing 1 defines an installation space 11. Some components of the plug device 100 can be installed in the installation space 11 of the housing 1, reducing the risk of external environment interfering with the working of the components, making it easier for the components to work stably in the installation space 11, thereby improving the working stability of the plug device 100. Along the first direction, i.e. Figure 1 In the X direction, one end of the housing 1 is formed with a plug interface 12 connected to the installation space 11, and the adapter 200 can have a plug portion 201 adapted to the plug interface 12. Through the plug interface 12 and the plug portion 201, the plug device 100 and the adapter 200 can be plugged together to energize the adapter 200, which is convenient for experiments and tests on the adapter 200.

[0050] The electrode 2 is fixed in the installation space 11, for example, the electrode 2 can be fixed in the installation space 11 by bolts, or the electrode 2 can be clamped in the installation space 11, but the present application is not limited thereto, and the electrode 2 can also be fixed in the installation space 11 by other means, as long as the electrode 2 is fixed in the installation space 11. The electrode 2 extends along the first direction, that is, the electrode 2 extends along the X direction, and the electrode 2 is arranged corresponding to the plug interface 12. When the plug device 100 is plugged with the adapter 200, the electrode 2 can be connected to the adapter 200, which is conducive to the plug device 100 supplying power to the adapter 200 through the electrode 2.

[0051] The locking member 3 may be movably disposed on the housing 1, for example, the locking member 3 may be rotatably disposed on the housing 1, and the locking member 3 may be, but is not limited to, disposed as a hook-shaped structure, and the hook-shaped structure is suitable for hooking with the adapter 200 to achieve locking of the locking member 3 and the adapter 200. The locking member 3 may be movably disposed on the housing 1, and the locking member 3 may be a locking pin, and the adapter 200 may be provided with a locking hole, and the locking member 3 and the adapter 200 may be locked and unlocked by moving the locking pin into or out of the locking hole. However, the present application is not limited thereto, and the locking member 3 may also be movably disposed on the housing 1 in other ways, as long as the locking member 3 is movably disposed on the housing 1. The locking member 3 has a locking position and an unlocking position relative to the housing 1. When the plug device 100 and the adapter 200 are plugged and matched, the locking member 3 is in the locking position. At this time, the locking member 3 and the adapter 200 are locked, which improves the locking reliability of the plug device 100 and the adapter 200, thereby improving the current stability between the plug device 100 and the adapter 200, reducing the risk of burning the plug device 100, and further reducing the risk of leakage of the plug device 100, thereby improving the safety of the use of the plug device 100. When it is necessary to separate the plug device 100 from the adapter 200, the locking member 3 can be moved to the unlocking position, and the locking member 3 is separated from the adapter 200. At this time, the locking member 3 and the adapter 200 are unlocked to allow the plug device 100 to be removed from the adapter 200.

[0052] Specifically, the housing 1 defines an installation space 11, and the electrode 2 is fixedly installed in the installation space 11, which reduces the risk of external environment interfering with the operation of the electrode 2, and facilitates the electrode 2 to stably operate in the installation space 11, thereby improving the power supply stability of the plug device 100. Figure 1 In the X direction, one end of the housing 1 is formed with a plug interface 12 connected to the installation space 11, the electrode 2 extends along the first direction and the electrode 2 is correspondingly arranged with the plug interface 12. When the plug interface 12 is plugged with the plug portion 201 of the adapter 200, it is convenient for the plug device 100 to supply power to the adapter 200 through the electrode 2, thereby facilitating experiments and tests on the adapter 200. At this time, the locking member 3 is in the locking position, and the locking member 3 is locked with the adapter 200. Compared with the traditional handheld plug, the risk of the plug interface 12 and the adapter 200 being loosely plugged is reduced, and there is no need for the operator to continuously tighten the plug, which is conducive to achieving an automated production effect.

[0053] When the adapter 200 is a steering gear and a functional test is performed on the steering gear, the plug device 100 and the steering gear are locked by the locking member 3, which can improve the current stability between the plug device 100 and the steering gear, improve the accuracy of the steering gear test results, and reduce the risk of burning the plug device 100, thereby reducing the risk of leakage of the plug device 100 and improving the safety of the use of the plug device 100. When the adapter 200 is completed and the plug device 100 needs to be separated from the adapter 200, the locking member 3 is driven to move to the unlocking position, at which time the locking member 3 and the adapter 200 are unlocked to allow the plug device 100 to be removed from the adapter 200.

[0054] Furthermore, the housing 1 may include a cover body 13 and a protective cover 14. For example, the cover body 13 and the protective cover 14 may be made of, but not limited to, plastic or industrial rubber. The present application takes the example of the cover body 13 and the protective cover 14 being made of plastic. When the operator assembles the plug device 100 and the adapter 200 by holding the protective cover 14, the protective cover 14 being made of plastic can reduce the risk of electric shock for the operator and improve the operator's work safety.

[0055] The cover body 13 and the protective cover 14 may be provided with a plurality of assembly holes corresponding to each other. The plug device 100 may further include a plurality of threaded sleeves 8, which are respectively assembled in the plurality of assembly holes of the protective cover 14. The threaded sleeves 8 are threadedly locked with the corresponding assembly holes. Bolts are passed through the assembly holes of the cover body 13 and connected to the corresponding threaded sleeves 8, so that the cover body 13 and the protective cover 14 can be reliably assembled. By providing the threaded sleeves 8, the risk of damage to the assembly holes of the cover body 13 or the protective cover 14 caused by directly connecting the cover body 13 and the protective cover 14 with bolts is reduced, thereby improving the connection reliability of the cover body 13 and the protective cover 14.

[0056] Therefore, by providing the locking member 3, the plug device 100 and the adapter 200 can be reliably locked or unlocked. When the plug device 100 and the adapter 200 are plugged in, the locking member 3 is in the locked position, which improves the locking reliability of the plug device 100 and the adapter 200, thereby improving the current stability between the plug device 100 and the adapter 200, reducing the risk of burning the plug device 100, and further reducing the risk of leakage of the plug device 100, thereby improving the safety of the use of the plug device 100.

[0057] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the locking member 3 extends along a first direction, and the rotation axis of the locking member 3 extending along a second direction is rotatably provided on the housing 1 so that the locking member 3 rotates to a locking position or an unlocking position, and the second direction is perpendicular to the first direction.

[0058] The locking member 3 can extend along a first direction, that is, Figure 1 In the X direction, the locking member 3 has a rotation axis, and the rotation axis extends along the second direction, and the second direction is located in a plane perpendicular to the first direction, for example: Figure 1 As shown, the second direction is Figure 1 The second direction is perpendicular to the first direction. The locking member 3 is rotatably provided on the housing 1 along the rotation axis so that the locking member 3 can be rotated to a locked position or an unlocked position. When the plug device 100 and the adapter 200 need to be plugged and assembled, the locking member 3 is rotated to the locked position, at which time the locking member 3 and the adapter 200 are locked, thereby improving the plugging reliability of the plug device 100 and the adapter 200. When the plug device 100 and the adapter 200 need to be separated, the locking member 3 can be rotated in the opposite direction so that the locking member 3 is in the unlocked position, at which time the locking member 3 and the adapter 200 are unlocked so that the plug device 100 is removed from the adapter 200, thereby achieving a reliable locking or unlocking effect of the plug device 100 and the adapter 200.

[0059] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the plug device 100 may further include: a mounting shaft 4, a side wall of the housing 1 is formed with a mounting groove 15 extending along a first direction, the mounting shaft 4 is located in the mounting groove 15 and extends along a second direction, the mounting shaft 4 is passed through the locking member 3 and assembled on the housing 1, and the central axis of the mounting shaft 4 is constructed as a rotation axis.

[0060] The plug device 100 may further include a mounting shaft 4, which is used to assemble the locking member 3. The side wall of the housing 1 is formed with a mounting groove 15 extending along the first direction, and further, the mounting groove 15 may be formed on the side wall of the protective cover 14. Alternatively, part of the mounting groove 15 is formed on the side wall of the protective cover 14, and another part of the mounting groove 15 is formed on the cover 13. The locking member 3 may be assembled in the mounting groove 15, reducing the risk of the locking member 3 falling off the plug device 100 due to interference from the external environment. The mounting shaft 4 is located in the mounting groove 15 and extends along the second direction. The locking member 3 may have a through hole 33 adapted to the mounting shaft 4. The mounting shaft 4 is inserted into the through hole 33 of the locking member 3, and the two ends of the mounting shaft 4 are respectively assembled with the housing 1. At this time, the central axis of the mounting shaft 4 is constructed as the rotation axis of the above-mentioned embodiment, so that the locking member 3 and the housing 1 can be rotatably connected, so that the locking member 3 can be smoothly rotated to the locked position or the unlocked position, thereby achieving the effect that the plug device 100 and the adapter 200 can be reliably locked or unlocked.

[0061] In some embodiments of the present invention, Figure 1 and Figure 3As shown, along the second direction, the mounting groove 15 has a first side wall 151 and a second side wall 152 opposite to each other, and both the first side wall 151 and the second side wall 152 are formed with an assembly groove 1521, and the two ends of the mounting shaft 4 are respectively assembled in the assembly groove 1521 of the first side wall 151 and the assembly groove 1521 of the second side wall 152.

[0062] Among them, along the second direction, the second direction is Figure 1 In the Y direction, the mounting groove 15 has a first side wall 151 and a second side wall 152, and the first side wall 151 and the second side wall 152 are arranged opposite to each other along the second direction. The first side wall 151 and the second side wall 152 are both formed with an assembly groove 1521, and the size of the assembly groove 1521 is adapted to the size of the mounting shaft 4, so that the mounting shaft 4 and the assembly groove 1521 can be assembled smoothly. Specifically, the installation shaft 4 is passed through the through hole 33 of the locking member 3, one end of the installation shaft 4 is assembled in the assembly groove 1521 of the first side wall 151, and the other end of the installation shaft 4 is assembled in the assembly groove 1521 of the second side wall 152, so that the locking member 3 is rotatably connected to the outer shell 1. By respectively assembling the installation shaft 4 at both ends in the assembly groove 1521 of the first side wall 151 and the assembly groove 1521 of the second side wall 152, the assembly reliability of the installation shaft 4 and the outer shell 1 can be improved, thereby improving the connection reliability of the locking member 3 and the outer shell 1, reducing the risk of the locking member 3 falling off the outer shell 1, and thereby improving the plug-in reliability of the plug device 100 and the adapter 200.

[0063] In some embodiments of the present invention, Figure 4 As shown, the plug device 100 may also include: an elastic member 5, which is assembled between the bottom wall 153 of the mounting groove 15 and the locking member 3. Along the first direction, the elastic member 5 is located on the side of the mounting axis 4 away from the plug interface 12. When the locking member 3 is in the locked position, the elastic member 5 is compressed.

[0064] The plug device 100 may further include an elastic member 5, for example, the elastic member 5 may be configured as a spring, or as a spring sheet, but the present application is not limited thereto, and the elastic member 5 may also be configured in other forms, as long as the plug device 100 includes the elastic member 5. The elastic member 5 is assembled between the bottom wall 153 of the mounting groove 15 and the locking member 3, for example, the elastic member 5 may be hooked between the bottom wall 153 of the mounting groove 15 and the locking member 3, or the elastic member 5 may be clamped between the bottom wall 153 of the mounting groove 15 and the locking member 3, but the present application is not limited thereto, and the elastic member 5 may also be assembled between the bottom wall 153 of the mounting groove 15 and the locking member 3 in other ways, as long as the elastic member 5 is assembled between the bottom wall 153 of the mounting groove 15 and the locking member 3.

[0065] The elastic member 5 can provide elastic force to the locking member 3. When the locking member 3 is in the locked position, the elastic member 5 is compressed. This arrangement can keep the locking member 3 in the locked position, which is conducive to the reliable locking of the plug device 100 and the adapter 200. As some embodiments of the present application, the locking member 3 can have a locking portion 31 and an operating portion 32. The locking portion 31 is located at one end of the locking member 3 close to the plug interface 12, and the operating portion 32 is located at one end of the locking member 3 away from the plug interface 12. Along the first direction, that is, Figure 1 In the X direction, the elastic member 5 is located on the side of the installation axis 4 facing away from the plug-in port 12 .

[0066] When the plug device 100 and the adapter 200 are plugged and matched, the locking member 3 is in the locked position, the elastic member 5 is compressed, and the elastic member 5 provides elastic force to the operating portion 32 away from the bottom wall 153 of the installation groove 15. Under the action of the installation shaft 4, the locking portion 31 is kept in the locked position, so that the locking portion 31 and the adapter 200 are reliably locked, and the plug device 100 and the adapter 200 are reliably locked. When the plug device 100 and the adapter 200 need to be separated, the operator presses the operating portion 32, and the operating portion 32 is forced to compress the spring and move toward the bottom wall 153 of the installation groove 15. Under the action of the installation shaft 4, the locking portion 31 is tilted in the direction away from the bottom wall 153 of the installation groove 15, and the locking member 3 is in the unlocked position, so that the locking portion 31 is separated from the adapter 200, and the locking member 3 is unlocked from the adapter 200, so that the plug device 100 and the adapter 200 are smoothly separated. It should be noted that when the plug device 100 and the adapter 200 are not plugged in, the locking member 3 is located at the locking position under the action of the elastic member 5 .

[0067] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the bottom wall 153 of the mounting groove 15 is formed with an avoidance opening 1531 adjacent to the plug-in port 12 , and along the first direction, the end of the locking member 3 close to the plug-in port 12 is formed with a locking portion 31 , and the avoidance opening 1531 is arranged corresponding to the locking portion 31 to avoid the locking portion 31 .

[0068] The bottom wall 153 of the installation groove 15 may be formed with an escape opening 1531, and the escape opening 1531 may be arranged at a position adjacent to the plug-in port 12, along the first direction, that is, Figure 1In the X direction, the locking member 3 is formed with a locking portion 31, and the locking portion 31 is arranged at the end close to the plug-in port 12. The avoidance opening 1531 is arranged corresponding to the locking portion 31, so that the avoidance opening 1531 avoids the locking portion 31, thereby reducing the risk of interference between the locking portion 31 and the bottom wall 153 of the installation groove 15. When the plug device 100 and the adapter 200 are plugged in, the locking portion 31 can be rotated into the installation space 11 through the avoidance opening 1531, so that the locking portion 31 and the adapter 200 are reliably locked, thereby achieving the plug-in reliability of the plug device 100 and the adapter 200.

[0069] In some embodiments of the present invention, Figure 1 As shown, the plug device 100 may further include: a mounting seat 6 , the mounting seat 6 is fixedly disposed in the mounting space 11 , and the electrode 2 is fixedly disposed on the mounting seat 6 .

[0070] Among them, the plug device 100 may also include a mounting seat 6, and the electrode 2 is fixed to the mounting seat 6. For example, the electrode 2 may be fixed to the mounting seat 6 by bolts, or the electrode 2 may be welded to the mounting seat 6, but the present application is not limited thereto. The electrode 2 may also be fixed to the mounting seat 6 by other means. As long as the electrode 2 is fixed to the mounting seat 6, the mounting seat 6 may position the electrode 2 to improve the working stability of the electrode 2. The mounting seat 6 and the electrode 2 are fixed in the installation space 11, reducing the risk of external environment interfering with the operation of the mounting seat 6 and the electrode 2, facilitating the stable operation of the mounting seat 6 and the electrode 2 in the installation space 11, and facilitating the reliable power supply of the plug device 100 to the adapter 200 through the electrode 2, thereby improving the working stability of the plug device 100.

[0071] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, a first limiting surface 111 and a second limiting surface 112 are formed in the installation space 11. The first limiting surface 111 and the second limiting surface 112 are opposite to each other and spaced apart along a first direction. The mounting seat 6 is located between the first limiting surface 111 and the second limiting surface 112, and the mounting seat 6 is in contact with both the first limiting surface 111 and the second limiting surface 112.

[0072] Among them, a first limiting surface 111 and a second limiting surface 112 are formed in the installation space 11, and the first limiting surface 111 and the second limiting surface 112 are arranged opposite to each other along the first direction, and the first limiting surface 111 and the second limiting surface 112 are arranged to be spaced apart so that the mounting seat 6 can be located between the first limiting surface 111 and the second limiting surface 112, and the first limiting surface 111 and the second limiting surface 112 can both limit the mounting seat 6, and the mounting seat 6 abuts against the first limiting surface 111 and the second limiting surface 112 to limit the movement of the mounting seat 6 in the installation space 11 along the first direction, thereby improving the working stability of the mounting seat 6, which is conducive to the plug device 100 to reliably supply power to the adapter 200 through the electrode 2.

[0073] Further, a first limiting surface 111 is formed on the cover body 13, and a second limiting surface 112 is formed on the protective cover 14. Specifically, a first space is formed in the cover body 13, and a second space is formed in the protective cover 14. The first space and the second space are jointly configured as the installation space 11. A limiting boss protruding toward the first space is formed on the cover body 13, and the surface of the limiting boss facing the plug interface 12 is configured as the first limiting surface 111. A limiting boss protruding toward the second space is formed on the protective cover 14, and the surface of the limiting boss facing the wiring harness through hole 16 is configured as the second limiting surface 112.

[0074] In some embodiments of the present invention, Figure 1 As shown, the housing 1 is formed with a harness through hole 16 communicating with the installation space 11 .

[0075] Among them, the housing 1 may be formed with a harness through hole 16, the harness through hole 16 is connected to the installation space 11, the harness through hole 16 is a through hole 33, and the harness can be passed through the harness through hole 16, so that the harness can be connected to the electrode 2 in the installation space 11 through the harness through hole 16, and the harness can supply power to the adapter 200 through the electrode 2, so as to facilitate experiments and tests on the adapter 200. As some embodiments of the present application, the inner diameter of the harness through hole 16 can be adapted to the outer diameter of the harness, so that the harness can be limited by the harness through hole 16 to reduce the probability of the harness moving.

[0076] Furthermore, there may be two wiring harnesses, and the two wiring harnesses may be respectively configured as a positive wiring harness 161 and a negative wiring harness 162 , and the positive wiring harness 161 and the negative wiring harness 162 are respectively connected to the electrodes 2 .

[0077] In some embodiments of the present invention, Figure 1 As shown, the plug device 100 may further include a plug 7 , which is suitable for being assembled in the wiring harness through hole 16 .

[0078] Among them, the plug device 100 can also include a plug 7, which can be but is not limited to being constructed of rubber material. The plug 7 is suitable for being assembled in the wiring harness via 16, further reducing the probability of wiring harness movement, and can also reduce the risk of external dust and water vapor entering the installation space 11, thereby reducing the risk of leakage or even burning of the plug device 100 due to water vapor, which is conducive to further improving the safety of the plug device 100.

[0079] In some embodiments of the present invention, Figure 1 As shown, along the first direction, a harness through hole 16 is formed at the other end of the housing 1 .

[0080] Among them, along the first direction, that is, Figure 1 In the X direction, one end of the shell 1 is formed with a plug interface 12 connected to the installation space 11, and the other end of the shell 1 is formed with a wire harness via 16, that is, the plug interface 12 and the wire harness via 16 are respectively formed at the two ends of the shell 1. As an example, the wire harness via 16 is formed on the end wall of the cover body 13 away from the plug interface 12, and the wire harness can be passed through the wire harness via 16 to connect with the electrode 2. By forming the plug interface 12 and the wire harness via 16 at the two ends of the shell 1 respectively, the plug interface 12 can be separated from the wire harness via 16, thereby reducing the probability of the wire harness blocking the plug interface 12, and facilitating the plug connection between the plug interface 12 and the adapter 200.
