Description

Technical Field

[0001] This utility model relates to the field of combined stud technology, and more specifically, to a combined stud for grounding and fixing a vehicle communication module. Background Technology

[0002] The vehicle communication module is a core component for realizing functions such as vehicle networking, positioning, and remote control. Its installation and fixation must meet the dual requirements of "stable structure" and "reliable grounding": On the one hand, the vehicle will generate continuous vibration during driving. If the module is not fixed firmly, it is easy to shift or loosen, resulting in poor contact of the communication interface and signal interruption; on the other hand, the communication module will generate electromagnetic interference (EMI) when it is working. It is necessary to conduct the interference current into the vehicle body through reliable grounding, while preventing external interference from entering the module and ensuring communication quality.

[0003] Traditionally, the fixing and grounding structures are separate. The communication module needs to be fixed to the vehicle body bracket with an independent screw, and then connected to the vehicle body grounding terminal through an additional grounding wire (such as copper braided wire). This increases the installation time. In addition, traditional fixing screws are mostly ordinary single nut structures, and the gap between them and the module mounting hole is relatively large. When the vehicle vibrates, the thread engagement gap is prone to increase, causing the screw to loosen and affecting the fixing effect. Therefore, a combined stud for grounding and fixing the vehicle communication module is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a combined stud for grounding and fixing a vehicle communication module, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined stud for grounding and fixing a vehicle communication module, comprising a first screw, an anti-slip plate fixedly connected to one end of the first screw, a hexagonal screw head fixedly connected to one side of the anti-slip plate, a compression pad fixedly connected to the side of the anti-slip plate away from the hexagonal screw head, two mounting nuts symmetrically sleeved on the outside of the first screw, and a compression plate fixedly connected to the opposite end of the two mounting nuts. By positioning the two mounting nuts on both sides of the mounting wall of the vehicle communication module, the vehicle communication module can be compressed and installed, and the compression plate increases the friction of the mounting surface to prevent loosening. A insert rod is inserted into the middle of the first screw, and a rack is fixedly connected to the top of the insert rod. A receiving groove is opened on one side of the hexagonal screw head, and a screw head is set in the middle of the receiving groove. A second screw is fixedly connected to one end of the screw head, and a connecting block is fixedly connected to one end of the insert rod. An internal hexagonal groove is opened on one side of the screw head, which facilitates the rotation of the screw head, thereby controlling the rotation and movement of the second screw, driving the insert rod to slide inside the first screw, so that the rack moves and generates a squeezing force with the teeth inside the mounting nut, eliminating the thread fit clearance, preventing loosening caused by vibration, and improving the fixing strength. One of the mounting nuts is fixedly connected to a positioning ring on one side, and a grounding plate is sleeved in the middle of the positioning ring. The positioning ring facilitates the positioning of the grounding plate and improves the stability of the grounding plate installation. The compression pad compresses one side of the grounding plate, further improving the stability of the grounding plate. The grounding plate also facilitates the connection of the grounding wire.

[0006] Preferably, one side of the teeth of the rack corresponds to the thread on the outer surface of the first screw, and the mounting nut is threadedly connected to the first screw, which does not affect the rotation of the mounting nut on the outer surface of the first screw, thus facilitating normal installation and fixing.

[0007] Preferably, the second screw passes through the middle of the hexagonal screw head and the anti-slip plate and extends to the middle of the first screw. The second screw is threadedly connected to the hexagonal screw head and the anti-slip plate. By rotating the second screw, the second screw can be rotated and displaced at the same time.

[0008] Preferably, the connecting block has a "T" shaped cross-section and is embedded in the middle of one end of the second screw, connecting the second screw to the insert rod so that the insert rod moves with the movement of the second screw.

[0009] Preferably, the positioning ring is located on the side of the mounting nut near the anti-slip plate, the compression pad is offset from the positioning ring, and the wall of the compression pad is in contact with the wall of the grounding plate. The positioning ring limits the grounding plate, and the compression pad compresses the grounding plate to achieve tight fixation, so as to avoid the grounding plate from loosening and affecting the grounding connection effect.

[0010] The technical effects and advantages of this utility model are as follows: 1. This utility model first limits the grounding plate by setting a positioning ring, and then squeezes the grounding plate by the cooperation of the extrusion pad and the mounting nut, which can fix the position of the grounding plate and improve the grounding connection effect. The extrusion plate is squeezed and fixed by the two mounting nuts, which can facilitate the use of the fixed plate. Furthermore, by rotating the screw head, the second screw is controlled to drive the insertion rod and the rack to move, which can make the rack generate a squeezing force to eliminate the thread fit gap, prevent loosening caused by vibration, and improve the fixing strength. 2. This utility model also increases the friction of the mounting surface by setting the extrusion plate to prevent loosening. The internal hexagonal groove facilitates the rotation of the screw head, thereby controlling the rotation and movement of the second screw. One side of the rack teeth corresponds to the thread on the outer surface of the first screw, so as not to affect the rotation of the mounting nut on the outer surface of the first screw, which facilitates normal installation and fixing. The rack can prevent the insertion rod from rotating, facilitate horizontal movement drive, and improve the use effect. In summary, through the interaction of the above-mentioned multiple effects, the grounding connection effect can be improved, the combination installation can be facilitated to reduce installation time, the thread fit gap can be eliminated, the loosening caused by vibration can be prevented, and the fixing strength can be improved.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] As attached Figure 1-4The example shown is a combination stud for grounding and fixing a vehicle communication module, including a first screw 1. One end of the first screw 1 is fixedly connected to an anti-slip plate 2. One side of the anti-slip plate 2 is fixedly connected to a hexagonal screw head 3. The side of the anti-slip plate 2 away from the hexagonal screw head 3 is fixedly connected to a compression pad 4. Two mounting nuts 12 are symmetrically sleeved on the outside of the first screw 1. The opposite ends of the two mounting nuts 12 are fixedly connected to a compression plate 13. By positioning the two mounting nuts 12 on both sides of the mounting wall of the vehicle communication module, the vehicle communication module can be compressed and installed. The compression plate 13 increases the friction of the mounting surface and prevents loosening. A rod 5 is inserted into the middle of the first screw 1, and a rack 6 is fixedly connected to the top of the rod 5. A receiving groove 11 is opened on one side of the hexagonal screw head 3, and a screw head 8 is set in the middle of the receiving groove 11. A second screw 7 is fixedly connected to one end of the screw head 8, and a connecting block 10 is fixedly connected to one end of the rod 5. An internal hexagonal groove 9 is opened on one side of the screw head 8, which facilitates the rotation of the screw head 8, thereby controlling the rotation and movement of the second screw 7, driving the rod 5 to slide inside the first screw 1, so that the rack 6 moves and generates a squeezing force with the teeth inside the mounting nut 12, eliminating the thread fit clearance, preventing loosening caused by vibration, and improving the fixing strength. One of the mounting nuts 12 is fixedly connected to a positioning ring 14 on one side. A grounding plate 15 is sleeved in the middle of the positioning ring 14. The positioning ring 14 facilitates the positioning of the grounding plate 15, improves the stability of the installation of the grounding plate 15, and the compression pad 4 compresses one side of the grounding plate 15, further improving the stability of the grounding plate 15. The grounding plate 15 also facilitates the connection of the grounding wire.

[0018] As attached Figure 1-4 As shown, one side of the teeth of the rack 6 corresponds to the thread on the outer surface of the first screw 1. The mounting nut 12 is threadedly connected to the first screw 1. The second screw 7 passes through the middle of the hexagonal head 3 and the anti-slip plate 2 and extends to the middle of the first screw 1. The second screw 7 is threadedly connected to the hexagonal head 3 and the anti-slip plate 2. The cross-sectional shape of the connecting block 10 is set to "T". The connecting block 10 is embedded in the middle of one end of the second screw 7. The positioning ring 14 is set on the side of the mounting nut 12 near the anti-slip plate 2. The compression pad 4 and the positioning ring 14 are staggered. The wall of the compression pad 4 fits against the wall of the grounding plate 15, allowing the mounting nut 12 to rotate on the outer surface of the first screw 1 without affecting normal installation and fixing. By rotating the second screw 7, the second screw 7 can be displaced while rotating, connecting the second screw 7 to the insertion rod 5, so that the insertion rod 5 moves with the movement of the second screw 7. The positioning ring 14 limits the grounding plate 15, and the compression pad 4 squeezes the grounding plate 15 to achieve tight fixing, preventing the grounding plate 15 from loosening and affecting the grounding connection effect.

[0019] The working principle of this utility model is as follows: When in use, one end of the grounding plate 15 is put on the positioning ring 14 and the mounting nut 12 with the positioning ring 14 is put on the first screw 1. By rotating the mounting nut 12 and cooperating with the anti-slip plate 2, the grounding plate 15 is pressed and fixed. Then, the first screw 1 is passed through the mounting hole of the vehicle communication module and the support plate hole, and the mounting nut 12 is rotated to control the extrusion plate 13 to extrude and fix the communication module and the support plate. Then, rotate the screw head 8 to control the second screw 7 to drive the insertion rod 5 to move, so that the rack 6 generates a squeezing force to eliminate the thread fit clearance, prevent loosening caused by vibration, and improve the fixing strength. Then, it can be completed by connecting one end of the grounding plate 15 to the grounding wire.

[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
