In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.

Referring to fig. 1 and 2, the present embodiment provides a fixture 10 for a vehicle-mounted camera 20. The in-vehicle camera 20 includes a circuit board 22 and a socket 24 provided on the circuit board 22. The receptacle 24 includes a connector barrel 242.

Referring to fig. 3 and 4, the fixture 10 includes a base 12 and a plug structure 14. The plug structure 14 is disposed on the base 12. The plug structure 14 includes a first sleeve 142 and a second sleeve 144 disposed coaxially with the first sleeve 142 and sleeved outside the first sleeve 142. The second sleeve 144 is configured to guide the connector barrel 242 between the first sleeve 142 and the second sleeve 144 such that the connector barrel 242 and the first sleeve 142 are coaxially disposed.

In the fixture 10 of the embodiment of the application, the second sleeve 144 can guide the connecting cylinder 242 between the first sleeve 142 and the second sleeve 144, and the connecting cylinder 242 and the first sleeve 142 are coaxially arranged, so that the position of the vehicle-mounted camera 20 on the fixture 10 can be fixed, and the vehicle-mounted camera 20 can be ensured to smoothly communicate with a test device through the fixture 10, so that the test can be smoothly performed.

Specifically, the jig 10 may be used to fix a small-sized camera, for example, a camera such as an in-vehicle camera or a camera module for home monitoring, and further debug the imaging effect of the camera, such as focusing, of the fixed camera by a testing device. The fixture 10 needs to be frequently docked with different cameras, and thus, the fixture 10 itself needs to have certain rigidity and hardness to ensure the dimensional accuracy, the position accuracy and the shape accuracy of the parts of the fixture, and it can be understood that the fixture 10 can prolong the service life of the fixture when ensuring the rigidity and the hardness of the fixture. As the material for forming the jig 10, 45 steel, 20Cr (a steel grade, low hardenability carburized steel) or the like can be used.

The fixture 10 includes a base 12. The base 12 may be used to carry other components. The base 12 can be set up to the square, is provided with square through hole in the middle of the base 12, and the four corners of base 12 can be provided with the screw hole, so, anchor clamps 10 can debug the camera on the wall through the vertical fixing of screw hole of base 12 on the wall, and anchor clamps 10 also can debug the camera through the special treatment platform through the screw hole level fixation of base 12.

The base 12 is provided with a plug-in structure 14, the plug-in structure 14 may be used to connect related structures of the camera, for example, the plug-in structure 14 may be connected with a socket 24 on a circuit board 22 of the vehicle-mounted camera 20 to play a role of fixing the vehicle-mounted camera 20, and further may perform operations such as device debugging, for example, focusing on the vehicle-mounted camera 20 fixed on the fixture 10 by using a testing device. The plug structure 14 may be provided with a base 146. Meanwhile, the pedestal 12 is also provided with an upward jacking mechanism 128 for positioning the vehicle-mounted camera 20, and the upward jacking mechanism 128 is used for being matched with a relevant structure of the vehicle-mounted camera 20 so as to achieve the function of positioning the vehicle-mounted camera 20.

As shown in fig. 4, the plug structure 14 is provided with a first sleeve 142 and a second sleeve 144. The first sleeve 142 and the second sleeve 144 are coaxially disposed, specifically, the first sleeve 142 and the second sleeve 144 are both of a cylindrical structure, the first sleeve 142 is disposed in a cavity of the second sleeve 144, the first sleeve 142 and the second sleeve 144 are the same central axis, or a distance between the central axes of the first sleeve 142 and the second sleeve 144 is within a predetermined range, so we can say that the first sleeve 142 and the second sleeve 144 are coaxially disposed.

Similarly, the connector barrel 242 and the first sleeve 142 being coaxially disposed means that the distance between the central axes of the connector barrel 242 and the first sleeve 142 is within a predetermined range.

As shown in FIG. 4, the second sleeve 144 may be adapted to couple to the connector barrel 242, with the second sleeve 144 having a minimum inner diameter greater than the maximum outer diameter of the connector barrel 242, such that the connector barrel 242 may be fitted into the second sleeve 144. Additionally, the maximum outer diameter of the first sleeve 142 should be less than the minimum inner diameter of the connector barrel 242 so that the first sleeve 142 can fit into the connector barrel 242. Because the connecting sleeve 242 is connected to the first sleeve 142 after being connected to the second sleeve 144, the second sleeve 144 is higher than the first sleeve 142, for example, the second day sleeve 144 may be higher than the first sleeve 142 by 1.0mm to 1.5 mm. Thus, during the connection process between the plug structure 14 and the receptacle 24, the second sleeve 144 is connected to the connecting cylinder 242 before the first sleeve 142, and the second sleeve 144 can accurately guide the first sleeve 142 to be installed into the receptacle 24.

Referring to FIG. 3, in some embodiments, the base 12 includes a support member 124 and a connecting member 126. The connecting member 126 is detachably provided on the supporting member 124. The plug-in structure 14 is arranged on the connecting piece 126.

In this manner, when the connector 126 is damaged, the connector 126 can be directly removed from the base 12 and replaced with a new connector 126, saving cost and increasing the service life of the clamp 10. And the plug-in structure 14 provided on the connector 126 can be connected with the in-vehicle camera 20.

Specifically, the supporting member 124 includes a plate body 1230, and the plate body 1230 is used for supporting other components. The support 124 is provided with a first mounting part 1240, and the first mounting part 1240 includes a first mounting part main body 1242 and a mounting side plate 1244. The mounting side plate 1244 may be fixed to the support 124 by a screw fastening method, or may be fixed to the support 124 by a welding method. The connector 126 is mounted to the support member 124 by a first mounting portion 1240.

The second mounting portion 1250 is mounted above the first mounting portion 1240, and in some examples, the second mounting portion 1250 may be fixed to the first mounting portion 1240 by means of screw fixation, or the second mounting portion 1250 may be fixed to the first mounting portion 1240 by means of welding. As shown in fig. 3, the second mounting portion 1250 is formed in an "L" shape, and a threaded through hole and a first positioning hole 1252 are formed at an end of the second mounting portion 1250 away from the first mounting portion 1240 to connect with the first connection portion 1260.

Referring to fig. 1 and 3, in some embodiments, the connector 126 includes a first connector 1260 and a second connector 1270. The second connection portion 1270 is connected to the first connection portion 1260. The first connection section 1260 is fixedly connected with the support 124. The plug structure 14 is disposed on the second connecting portion 1270, and a gap 127 is formed between the second connecting portion 1270 and the support 124.

In this manner, the connection member 126 and the plug structure 14 provided on the connection member 126 can be indirectly fixed to the support member 124 by fixing the first connection section 1260 of the connection member 126 to the support member 124.

In some examples, the first connection portion 1260 is provided with a second positioning hole 1262, which can be used to match with the first positioning hole 1252 of the second mounting portion 1250 and be fixed by a cylindrical pin. The first connection portion 1260 is also provided with a threaded hole, and the first connection portion 1260 can be fixed on the second mounting portion 1250 by a screw.

An end of the second connecting portion 1270 away from the second mounting portion 1250 is connected to the base 146 of the plug structure 14, and in some examples, the base 146 may be welded to the second connecting portion 1270 by welding, so that the plug structure 14 is connected to the connector 126. The second connection portion 1270 is higher than the first connection portion 1260, and the second connection portion 1270 may be provided in an irregular shape, and a chamfered structure is provided at a position near the upper lifting mechanism 128 to facilitate installation of the second connection portion 1270.

Referring to FIG. 6, in some embodiments, the wall thickness A of the second sleeve 144 ranges from 1.0mm to 1.4 mm. For example, the wall thickness A of the second sleeve 144 may be 1.0mm, 1.1mm, 1.2mm, 1.3mm, or 1.4mm, among other dimensions.

In this manner, a suitable wall thickness A of the second sleeve 144 may ensure a stiffness and rigidity of the second sleeve 144 such that it is not easily damaged when the second sleeve 144 is coupled to the connector barrel 242.

Specifically, when the wall thickness a of the second sleeve 144 is set to be greater than 1.4mm, the second sleeve 144 may be squeezed or the like due to misalignment of the connecting tube 242 when the second sleeve 144 is introduced into the connecting tube 242. And the wall thickness a of the second sleeve 144 is less than 1.4mm, these press deformations and the like can be well resisted. If the wall thickness A of the second sleeve 144 is too small (e.g., less than 1.0mm), the second sleeve 144 may deform, crack, etc. due to the impact of the connector barrel 242.

Referring to fig. 4 and 6, in some embodiments, the second sleeve 144 includes an end surface 1442, an inner wall surface 1444, and a guide surface 1446, wherein the guide surface 1446 connects the end surface 1442 and the inner wall surface 1444.

In this manner, the guide surfaces 1446 may provide for more precise, easier, and faster connection of the second sleeve 144 to the connector barrel 242.

Specifically, the guiding surface 1446 may be provided with a certain slope, and the guiding surface 1446 is contracted from outside to inside. The end surface 1442 is disposed above the guide surface 1446, and the width of the end surface 1442 varies with the inclination of the guide surface 1446, and in some cases, when the inclination of the guide surface 1446 is sufficiently small, the width dimension of the end surface 1442 may be 0. Inner wall surface 1444 has no slope, and inner wall surface 1444 is disposed upright. The guide surface 1446 connects the inner wall surface 1444 and the end surface 1442. The inner wall 1444 and the guiding surface 1446 need to be provided with certain smoothness, for example, the roughness of the inner wall 1444 and the end surface 1442 can be less than or equal to ra3.2, so that in the installation process of the connecting cylinder 242 and the second sleeve 144, the connecting cylinder 242 cannot be in poor butt joint due to the fact that the roughness of the guiding surface 1446 or the inner wall 1444 is too large.

Referring to fig. 4 and 6, in some embodiments, the guiding surface 1446 is a conical surface having an apex located on the central axis of the second sleeve 144. Thus, the tapered guide surface 1446 provides guidance for the fitting of the connector barrel 242 into the second sleeve 144 during mating of the second sleeve 144 with the connector barrel 242. The guiding surface 1446 is expanded from bottom to top, so that the guiding surface 1446 has a larger accommodating space from bottom to top.

Specifically, during the process of mating the second sleeve 144 and the connecting cylinder 242, the connecting cylinder 242 first contacts the smooth guiding surface 1446, and because the guiding surface 1446 is contracted from top to bottom, the connecting cylinder 242 slides along the guiding surface 1446 and finally enters the inner wall 1444.

It will be appreciated that the second sleeve 144 is a cylinder, with the central axis of the second sleeve 144 being the axis of the cylinder.

Of course, in other embodiments, the guiding surface 1446 may have other shapes such as an arc surface.

Referring to FIG. 6, in some embodiments, the angle B of the guide surface 1446 with respect to the central axis of the second sleeve 144 may range from 30 to 60. For example, the angle of the included angle B is 30 °, 35 °, 40 °, 45 °, 50 °, 60 °, or the like.

Referring to FIG. 6, in some embodiments, the height C of the guide surface 1446 along the central axis of the second sleeve 144 may range from 0.2mm to 0.8 mm. For example, the height C of the guide surface 1446 may be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, or 0.8 mm.

The height C of the guide surface 1446 is too small, the guide surface 1446 cannot function as a guide, and if the height C of the guide surface 1446 is too large, there is a case where alignment is not possible.

Specifically, if the height C of the guide surface 1446 is too small, the connecting cylinder 242 may be caught on the second sleeve 144 during the mating of the second sleeve 144 with the connecting cylinder 242. If the height C of the guide surface 1446 is too high, the area of the guide surface 1446 is too large, wasting material making up the second sleeve 144.

Referring to FIG. 4, in some embodiments, the second sleeve 144 has a notch 1448, and the notch 1448 is connected to an end surface 1442 of the second sleeve 144.

Thus, the gap 1448 provides a certain deformation space for protecting the second sleeve 144 during the connection process between the second sleeve 144 and the connecting cylinder 242.

Specifically, the gap 1448 communicates between an inner wall surface 1444 of the second sleeve 144 and an outer wall surface (not shown) of the second sleeve 144. Looking down on the notch 1448 from above the second sleeve 144, the notch 1448 resembles a groove, and the notch 1448 is provided with an opening communicating with the end face 1442. The connection of the second sleeve 144 to the connector barrel 242 is not a smooth process, and during the connection process, the connector barrel 242 may be deflected from its original trajectory, causing compression of the second sleeve 144, causing it to deform. The gap 1448 may provide a certain deformation space when the connecting cylinder 242 is connected to the second sleeve 144, for example, in a process of connecting the second sleeve 144 and the connecting cylinder 242, if the connecting cylinder 242 deviates from the mounting rail, the connecting cylinder 242 may deviate from the gap 1448, and the connecting cylinder 242 may not press the second sleeve 144, so as to avoid deformation of the second sleeve 144, and prolong the service life of the second sleeve 144.

Referring to fig. 4, the circumferential length D of the gap 1448 along the second sleeve 144 (hereinafter referred to as length D) is in a range of 1.5mm to 3 mm. For example, the length D of the notch 1448 may be 1.5mm, 1.8mm, 2.0mm, 2.2mm, 2.4mm, 2.6mm, or 3.0mm, among other dimensions.

The height F of the notch 1448 may range from 1.5mm to 3.0mm in a direction perpendicular to the central axis of the second sleeve 144, for example, the height F of the notch 1448 may be 1.5mm, 1.8mm, 2.0mm, 2.2mm, 2.4mm, 2.6mm, or 3.0 mm. Specifically, the notch 1448 may be a square notch 1448 with a length D of 3mm and a height F of 3mm, so that the notch 1448 may provide more deformation space. It is understood that the notch 1448 may have other dimensions, and the above list is only one specific embodiment of the present invention, and should not be considered as limiting the scope of the present invention.

Referring to fig. 7 and 8, in some embodiments, the receptacle 24 includes a mating end 244 disposed within the connector barrel 242. The fixture 10 includes a pin 16, the pin 16 being disposed within the first sleeve 142 and coaxially disposed with the first sleeve 142. The contact pin 16 is configured to be inserted into the insertion end 244 and electrically connected to the circuit board 22, and the end surface 1442 of the second sleeve 144 protrudes from the end of the contact pin 16.

Thus, the pin 16 is inserted into the insertion end 244 and electrically connected to the circuit board 22, so that camera imaging effects such as focusing of the vehicle-mounted camera 20 can be debugged through the testing device.

The contact 16 and the first sleeve 142 are coaxially arranged, specifically, the contact 16 is a cylinder, the contact 16 is arranged in the cavity of the first sleeve 142, the contact 16 and the first sleeve 142 have the same central axis, or the distance between the contact 16 and the central axis of the first sleeve 142 is in a very small range, so we can say that the contact 16 and the first sleeve 142 are coaxially arranged.

Referring to fig. 7 and 8, in some embodiments, the end of the connecting cylinder 242 has a guiding structure 246, and the guiding structure 246 guides the first sleeve 142 such that the first sleeve 142 can enter the inner wall of the connecting cylinder 242 along the guiding structure 246 to realize the butt joint of the pin 16 and the mating end 244. As shown in fig. 8, the shape of the insertion end 244 may be a three-piece curved plate structure similar to a clip. The three-lobed bent plate configuration may grip pin 16 as pin 16 is inserted into mating end 244. The pins 16 are connected to the three-piece board structure, so that the pins 16 can be electrically connected to the circuit board 22.

Referring to FIG. 2, in some embodiments, the height K of the end 1442 of the second sleeve 144 that protrudes beyond the end of the pin 16 ranges from 1.3mm to 1.5 mm. For example, the height k may be 1.3mm, 1.4mm, or 1.5mm, among other dimensions.

The end surface 1442 of the second sleeve 144 protrudes beyond the end of the pin 16 by a certain height K, so that the second sleeve 144 can guide the connecting cylinder 242 to engage with the first sleeve 142, and the pin 16 can be protected from damage, thereby prolonging the service life.

Specifically, the height K of the end surface 1442 of the second sleeve 144 that protrudes beyond the end of the pin 16 may be 1.5 mm. During the connection process of the inserting structure 14 and the connecting cylinder 242, the second sleeve 144 contacts the connecting cylinder 242 before the first sleeve 142 contacts the connecting cylinder 242, the connecting cylinder 242 enters the inner cavity of the second sleeve 144 along the guiding surface 1446 of the second sleeve 144, and then the guiding structure 246 of the connecting cylinder 242 guides the first sleeve 142 into the inner cavity of the connecting cylinder 242, so that the pin 16 can be accurately inserted into the inserting end 244 and electrically connect the circuit board 22.

Referring to fig. 1 and 9, the present embodiment provides a connection assembly 100, where the connection assembly 100 includes a fixture 10 and a vehicle-mounted camera 20. The in-vehicle camera 20 includes a circuit board 22 and a socket 24 provided on the circuit board 22. The receptacle 24 includes a connector barrel 242, the connector barrel 242 being coaxially disposed with the first sleeve 142.

In the connection assembly 100 of the embodiment of the present application, the second sleeve 144 may guide the connection cylinder 242 to be aligned with the first sleeve 142, so that the first sleeve 142 and the connection cylinder 242 are coaxially disposed.
