Description

Technical Field

[0001] This utility model relates to the field of trailer plug technology, and in particular to a ten-pin trailer plug. Background Technology

[0002] Trailer plugs are metal connectors used for vehicle connections and are widely used in automotive molds, hot runner systems, mining equipment, injection molding machines, medical equipment, snow detection devices, electric automated vehicles, drainage and fire-fighting equipment, lifting machinery, and industrial automation. They are not only compatible with various circuits but also robust, durable, and offer excellent mechanical and electrical stability.

[0003] Chinese Patent Publication No. CN215579313U, published on January 18, 2022, discloses a trailer plug, including a plug socket and a plug. The plug socket has a mounting base plate, and the mounting base plate is connected to a mounting groove. The plug is slidably connected to the mounting groove, and a replaceable connector is sleeved inside the plug. The plug is connected to an electrical wire. The drawback of this technical solution is that when using the trailer plug, the mounting base plate is fixed to the trailer body. Although it achieves the connection effect of a trailer, when towing, because the trailer plug does not have a limiting component, the trailer may automatically travel a certain distance due to inertia during braking or driving, potentially colliding with the towed vehicle. This is unsafe and unreliable.

[0004] In summary, a structure can be set up to promptly block the vehicle when it is moving automatically, thereby reducing the probability of damage caused by contact. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of existing trailer plugs that do not have blocking components installed, and provides a ten-pin trailer plug that can reduce the probability of contact when the vehicle moves automatically.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ten-pin trailer plug includes a plug socket with a plug-in component, a plug core, and several connectors mounted on it. The rear end of the plug-in component is fitted onto the front end of the plug socket. The plug-in component has a through-tube and two limiting blocks mounted on it. The rear end of the through-tube is connected to the front end of the plug-in component, and the front end of the through-tube has a through-hole for installing an electrical wire. The plug core and connectors are both located at the rear end of the plug socket. The electrical wire is electrically connected to the plug core. The several connectors are evenly distributed. The two limiting blocks are symmetrically distributed at the left and right ends of the plug-in component. One end of each limiting block is connected to the plug-in component, and the distance between the other ends of the two limiting blocks is greater than the distance between the left and right ends of the plug socket.

[0008] This design allows for the installation of plugs, connectors, and several connectors on the plug socket. The rear end of the plug fits onto the front end of the plug socket. The plug has a through-tube and two limiting blocks. The rear end of the through-tube connects to the front end of the plug, and the front end of the through-tube has a through-hole where the wire is installed. The connectors and connectors are all located at the rear end of the plug socket. This design not only allows the wire to pass through the through-hole and connect to the connector on the plug socket, but also allows several evenly distributed connectors to connect to external vehicles. Thus, with the trailer hitch connected, vehicle towing can be performed. Of course, the two limiting blocks are symmetrically distributed on the left and right ends of the plug-in component. One end of the limiting block is connected to the plug-in component, and the distance between the other ends of the two limiting blocks is greater than the distance between the left and right ends of the plug socket. In other words, even if braking or deceleration occurs during vehicle towing, the vehicle will still move a certain distance due to inertia, and will be blocked by the limiting blocks, thus stopping the vehicle's movement. This prevents the vehicle from continuing to move and colliding with the towing vehicle or other objects, ensuring safety. This achieves the purpose of reducing the probability of collision when the vehicle moves automatically.

[0009] Preferably, a base is mounted on the plug socket, and the base is connected to the plug socket. The base has several mounting slots, each corresponding to a connector. The connector is connected to the plug socket via the base. This design, by mounting the base on the plug socket, allows the base to connect to the plug socket. The base has several mounting slots, each corresponding to a connector, allowing the connector to be placed within the slots and connected to the plug socket via the base. This enables the connection to the vehicle via an external connector, such as a chain, for towing.

[0010] Preferably, the plug socket is fitted with a connector sleeve, and both the plug socket and the base are placed inside the connector sleeve. The distance between the other ends of the two limiting blocks is greater than the distance between the left and right ends of the connector sleeve. This design, by fitting the connector sleeve onto the plug socket, ensures that both the plug socket and the base are placed inside the connector sleeve, thus protecting them and reducing the probability of damage to the plug socket and base from external objects. Furthermore, the distance between the other ends of the two limiting blocks is greater than the distance between the left and right ends of the connector sleeve, ensuring that the vehicle is promptly stopped by the limiting blocks during braking or deceleration, reducing the probability of collision with other objects.

[0011] Preferably, a plug-in block is installed on the plug-in sleeve. The plug-in block has a rectangular cross-sectional shape and is embedded in the plug-in sleeve. One end of the plug-in block is located at the rear end of the plug-in sleeve, and the other end is located between the front and rear ends of the plug-in sleeve. This design, by installing a plug-in block with a rectangular cross-sectional shape on the plug-in sleeve and embedding it in the sleeve, with one end at the rear end and the other end between the front and rear ends, enhances the robustness and stability of the plug-in sleeve. This, in turn, enhances the safety and stability of the components on the plug socket and base, reducing the probability of breakage or damage due to stress when controlling and towing vehicles.

[0012] Preferably, the base has several limiting grooves, and a mounting sleeve is fitted inside the base. The mounting sleeve has several annular grooves, and both the annular grooves and limiting grooves correspond one-to-one with the connecting parts. Several screws are installed on the mounting sleeve, which is then connected to the base via these screws. This design, with several limiting grooves on the base and a mounting sleeve with several annular grooves inside, each corresponding to a connecting part, ensures that the connecting parts fit securely and stably on the mounting sleeve and base. The screws on the mounting sleeve, connecting it to the base, facilitate the installation and removal of the mounting sleeve for replacement.

[0013] Preferably, the connector core includes several connectors, each connector being labeled. This design, by providing several connectors on the connector core, allows for different connections. The labels on the connectors indicate which device the connector is connected to.

[0014] The beneficial effects of this utility model are: it can reduce the probability of collision when the vehicle moves automatically; it facilitates the installation and removal of the ten-pin trailer plug; and it facilitates the connection of vehicles. Attached Figure Description

[0020] The utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 , Figure 2 and Figure 3 In the illustrated embodiment, a ten-pin trailer plug includes a plug socket 14, on which a plug-in component 4, a plug core 11, and several connectors 13 are mounted. The rear end of the plug-in component 4 is fitted onto the front end of the plug socket 14. A through tube 6 and two limiting blocks 5 are mounted on the plug-in component 4. The rear end of the through tube 6 is connected to the front end of the plug-in component 4. The front end of the through tube 6 has an insertion port 7, and a wire 8 is installed at the insertion port 7. The plug core 11 and connectors 13 are both located at the rear end of the plug socket 14. The wire 8 is electrically connected to the plug core 11. Several connectors 13 are evenly distributed. Two limiting blocks 5 are symmetrically distributed at the left and right ends of the plug-in component 4. One end of the limiting blocks 5 is connected to the plug-in component 4, and the distance between the other ends of the two limiting blocks 5 is greater than the distance between the left and right ends of the plug socket 14.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, a base 2 is mounted on the plug socket 14, and the base 2 is connected to the plug socket 14. The base 2 has several mounting slots 12, each corresponding to a connector 13. The connector 13 is connected to the plug socket 14 through the base 2. A plug sleeve 1 is fitted onto the plug socket 14, and both the plug socket 14 and the base 2 are placed inside the plug sleeve 1. The distance between the other ends of the two limiting blocks 5 is greater than the distance between the left and right ends of the plug sleeve 1. A plug-in block 3 is mounted on the plug sleeve 1. The plug-in block 3 has a rectangular cross-section and is embedded in the plug sleeve 1. One end of the plug-in block 3 is located at the rear end of the plug sleeve 1, and the other end of the plug-in block 3 is located between the front and rear ends of the plug sleeve 1. The base 2 has several limiting grooves 17, and an installation sleeve 16 is fitted inside the base 2. The installation sleeve 16 has several annular grooves 9, and the annular grooves 9 and limiting grooves 17 correspond one-to-one with the connectors 13. Several screws 15 are installed on the installation sleeve 16, and the installation sleeve 16 is connected to the base 2 by the screws 15. The plug core 11 includes several plug connectors, and the plug connectors are marked with a label 10.

[0023] First, ensure the structural stability and robustness of the ten-pin trailer plug, which means checking whether the installation of the ten-pin trailer plug is up to standard. The ten-pin trailer plug here includes a plug socket 14, a base 2, a plug-in component 4, a limiting block 5, a through tube 6, a wire 8, and a connector sleeve 1. The base 2 is located at the bottom of the plug socket 14 and is connected to the plug socket 14. The rear end of the plug-in component 4 is fitted onto the front end of the plug socket 14. The plug-in component 4 is equipped with the through tube 6 and two limiting blocks 5. The rear end of the through tube 6 is connected to the front end of the plug-in component 4. The front end of the through tube 6 has a through port 7, and the wire 8 is installed at the through port 7. The connector core 11 is located at the rear end of the plug socket 14. The base 2 has several limiting grooves 17 and is fitted with an installation sleeve 16. The installation sleeve 16 has several annular grooves 9. The annular grooves 9 and the limiting grooves 17 correspond one-to-one with the connector 13. In other words, the connector 13 is fitted into the annular grooves 9 on the installation sleeve 16 and connected to the base 2, which means that the connector 13 is stably limited. Of course, the wire 8 here can be electrically connected to the connector core 11 under the guidance of the insertion tube 6. If the connector 13 is only manually controlled, it is not only troublesome but also unreliable in stability. Therefore, several micro motors can be installed on the base 2. The motor shaft of the micro motor can be connected to the connector 13 through gears. Of course, the connector 13 needs to correspond one-to-one with the micro motor. The micro motor is electrically connected to the connector core 11, which means that the operation of the micro motor can be electrically controlled, so that the motor shaft drives the gear to rotate, thereby driving the connector 13 to rotate. The connector 13 can be connected to the base 2 through a rolling bearing. An upper limit plate is installed at the end of the connector 13. The diameter of the upper limit plate needs to be larger than the inner diameter of the rolling bearing. The outer diameter of the rolling bearing is connected to the base 2. Then the rotation of the connector 13 can connect to external components, such as the rotation of a connecting chain, which can be connected to a vehicle that needs to be towed.

[0024] Next comes the towing operation. With the connecting chain in place, the vehicle can be towed. However, if braking or deceleration is needed, it must be controlled. Due to inertia, the moving vehicle will still travel a distance. The two limiting blocks 5 installed on the plug-in component 4 can then prevent the vehicle from moving. One end of each limiting block 5 is connected to the plug-in component 4, and the distance between the other ends of the two limiting blocks 5 is greater than the distance between the left and right ends of the plug sleeve 1. The plug sleeve 1 is fitted onto the plug socket 14, meaning both the plug socket 14 and the base 2 are placed inside the plug sleeve 1. Therefore, the limiting blocks 5 effectively block the vehicle, thus reducing the probability of collisions when the vehicle moves automatically.

[0025] Of course, the materials of the plug sleeve 1, base 2, plug-in block 3, plug-in component 4, limit block 5, insertion tube 6, connector 13, plug socket 14 and mounting sleeve 16 can all be made of sturdy and durable steel, thereby enhancing the sturdiness and stability of the ten-core trailer plug. The electrical connection end of the wire 8 can be electrically connected to the switch inside the vehicle, and this switch naturally needs to be electrically connected to the power supply.
