Description

Technical Field

[0001] This utility model relates to the field of electrical connection equipment, and more particularly to a plug, connector and drone. Background Technology

[0002] In the context of rapid technological advancements, connectors, as indispensable components in electronic devices, play a crucial role in transmitting current and signals. Their quality, performance, and reliability directly impact the overall system's operational efficiency, safety, reliability, and functionality. With the rapid development of drone technology, connectors, as key components for information transmission and energy supply between various systems within a drone, directly influence the drone's overall performance and reliability. Drone connectors primarily enable signal and energy transmission between internal systems, including critical functions such as power supply, data, and communication. As the application of drones in aerial photography, agriculture, logistics, and rescue continues to expand, the demands on connectors are becoming increasingly stringent.

[0003] Connectors mainly consist of plugs and sockets. Currently, connectors vibrate during operation, which can easily lead to the plug becoming loose or falling off. This is especially true in high-vibration or high-impact devices such as drones, where the stability and reliability of the plug connection are poor. Utility Model Content

[0004] One objective of this utility model is to provide a plug that improves the stability and reliability of the connection.

[0005] Another objective of this utility model embodiment is to provide a connector and a drone, wherein the connector plug can improve the stability and reliability of the connection with the socket, making it easy to apply in drones.

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

[0007] On the one hand, a plug is provided, comprising:

[0008] The outer casing is provided with a first terminal hole;

[0009] The male terminal has an anti-detachment part;

[0010] A tail cap is installed on the housing, and the anti-detachment part of the male terminal is clamped between the tail cap and the housing;

[0011] PIN assembly, mounted on the housing;

[0012] as well as

[0013] The female terminal passes through the first terminal hole and is electrically connected to the PIN pin assembly;

[0014] The female terminal is provided with a guide platform, which covers the gap between the female terminal and the inner wall of the first terminal hole. The guide platform has a guide ring surface, which extends obliquely along the edge away from the female terminal and close to the first terminal hole.

[0015] Optionally, the housing is provided with a foolproof post.

[0016] Optionally, the housing has guide posts for inserting guide slots into the socket.

[0017] Optionally, the PIN assembly includes a circuit board and PIN bodies mounted on the circuit board; there are multiple PINs arranged at intervals.

[0018] Optionally, the housing has a boss, and the boss has a slot. The circuit board is snapped into the slot, the slot is connected to the first terminal hole, and the female terminal passes through the first terminal hole and is electrically connected to the circuit board.

[0019] Optionally, one end of the female terminal is welded to the circuit board and has a threaded connection hole.

[0020] Optionally, the outer casing has a first engaging portion, and the tail cover has a second engaging portion, wherein the tail cover is engaged with the outer casing via the first engaging portion and the second engaging portion.

[0021] Optionally, the outer casing has a second terminal hole and a terminal slot connected in sequence, the tail cover has a third terminal hole, one end of the male terminal passes through the second terminal hole, the other end of the male terminal passes through the third terminal hole, and the anti-detachment part of the male terminal is located in the terminal slot and clamped between the inner wall of the tail cover and the terminal slot.

[0049] like Figures 1 to 6 As shown, a plug 1 includes a housing 11, a male terminal 12, a tail cap 13, a pin assembly 14, and a female terminal 15. The housing 11 has a first terminal hole 111. The first terminal hole 111 is a circular hole that penetrates the housing 11 from top to bottom. The male terminal 12 has an anti-disengagement part 121. The anti-disengagement part 121 is an anti-disengagement ring integrally formed with the male terminal 12. The tail cap 13 is installed from bottom to top at the lower end of the housing 11. After the tail cap 13 is installed on the housing 11, the anti-disengagement part 121 of the male terminal 12 is clamped between the tail cap 13 and the housing 11, thereby preventing the male terminal 12 from detaching from the housing 11. The pin assembly 14 is installed on the housing 11. The pin assembly 14 includes a plurality of pin bodies 142, which are metallic materials used in the connector to complete the conduction (transmission) of electricity (signals). One end of the female terminal 15 passes through the first terminal hole 111 and is electrically connected to the PIN pin assembly 14. The other end of the female terminal 15 is provided with a chamfer or rounded corner and is used to electrically connect to the terminal on the socket 2. The chamfer or rounded corner facilitates the socket 2 to be fitted.

[0050] When the socket 2 and plug 1 are connected, the socket 2 fits onto the female terminal 15 of the plug 1 through the sleeve hole. The female terminal 15 is electrically connected to the terminal on the socket 2. There is a gap between the female terminal 15 and the inner wall of the sleeve hole of the socket 2, which can easily cause the socket 2 and plug 1 to wobble. In this application, the female terminal 15 is provided with a guide platform 151. The female terminal 15 is cylindrical, and the guide platform 151 is integrally formed with the female terminal 15. The guide platform 151 covers the gap between the female terminal 15 and the inner wall of the first terminal hole 111, which serves to prevent water and dust from entering and reduce the intrusion of air and moisture, thereby reducing the possibility of oxidation and corrosion. At the same time, the guide platform 151 can be used to snap into the sleeve hole of the socket 2. The guide platform 151 abuts against the inner wall of the sleeve hole of the socket 2 to fill the gap between the female terminal 15 and the inner wall of the sleeve hole of the socket 2, preventing the socket 2 and plug 1 from wobble. Specifically, the guide platform 151 has a guide ring surface 152, which guides the guide platform 151 to engage with the socket 2's sleeve hole. The guide ring surface 152 extends obliquely along the edge away from the female terminal 15 and close to the first terminal hole 111. The socket 2 is fitted onto the female terminal 15 from the upper end of the female terminal 15. The guide ring surface 152 extends obliquely from top to bottom along the axis away from the female terminal 15. The guide ring surface 152 forms an angle on the guide platform 151, allowing the socket 2 to engage with the guide platform 151 along the guide ring surface 152. The oblique setting of the guide ring surface 152 reduces friction and resistance during the engagement of the socket 2 and the plug 1. After the socket 2 and the plug 1 are engaged, the guide ring surface 152 guides the guide platform 151 to engage with the socket 2's sleeve hole and forms a certain self-locking effect, preventing accidental loosening or detachment and improving the stability and reliability of the connection between the socket 2 and the plug 1. The plug 1 of this application, through the guide platform 151 with a guide ring surface 152, ensures that after the socket 2 is plugged into the plug 1, the female terminal 15 can maintain tight contact with the electrical connection components such as the terminals of the socket 2. The guide platform 151 reduces the intrusion of air and moisture, thereby reducing the risk of poor contact, enhancing the reliability of signal transmission, and reducing contact resistance and signal loss. Therefore, when the plug 1 and socket 2 of this application are connected, a more stable connector structure can be assembled, reducing the probability of connector loosening and detachment due to vibration.

[0051] Optionally, the housing 11 is provided with a foolproof post 112. The foolproof post 112 is provided to prevent incorrect installation.

[0052] Optionally, the housing 11 has guide posts 113 for inserting into the guide groove of the socket 2. There are two guide posts 113 on the housing 11, spaced apart, with the male terminal 12 and female terminal 15 located between the two guide posts 113. One end of the guide post 113 is integrally formed and connected to the housing 11, while the other end has a chamfer or rounded corner to facilitate the insertion of the socket 2. The guide post 113 mates with the guide groove of the socket 2 to ensure precise alignment during connector insertion and removal.

[0053] In one embodiment, the PIN assembly 14 includes a circuit board 141 and a PIN body 142 mounted on the circuit board 141; there are multiple PINs arranged at intervals. The PIN assembly 14 has two PINs arranged at intervals, and the female terminal 15 has two female terminals arranged at intervals. The two PIN assemblies 14 correspond one-to-one with the two female terminals 15. The PIN assemblies 14 are located below the female terminals 15, and the female terminals 15 are connected to the circuit board 141.

[0054] Optionally, the housing 11 has a boss 114, which is integrally formed into the housing 11 and is located near the lower end of the housing 11. There are two bosses 114 spaced apart, and each boss 114 has a slot 115. The circuit board 141 is secured in the slot 115, and the PIN body 142 extends downward relative to the circuit board 141. The slot 115 and the first terminal hole 111 are connected sequentially from bottom to top through the housing 11, and the lower end of the female terminal 15 passes through the first terminal hole 111 and is electrically connected to the circuit board 141.

[0055] Furthermore, the lower end of the female terminal 15 is welded to the circuit board 141 and has a threaded connection hole 153. The female terminal 15 is connected to the circuit board 141 (PCB) by welding. By directly welding the female terminal 15 to the circuit board 141, a stable and durable electrical connection is formed. This connection method can effectively reduce contact resistance and signal loss, thereby improving the reliability of the electrical connection. The welding method firmly fixes the female terminal 15 to the circuit board 141, reducing the risk of loosening or falling off due to vibration or impact. This mechanical stability is particularly critical in applications such as automobiles and drones that need to withstand complex environmental conditions, making the equipment design more compact and improving the overall quality of the product. In addition, the lower end of the female terminal 15 has a pre-drilled M3 threaded connection hole 153, which can be used to add an M3 bolt for reinforcement when connecting to the PCB, further improving the connection strength and stability.

[0056] In one embodiment, the outer casing 11 has a first engaging portion 116, and the tail cover 13 has a second engaging portion 131. The tail cover 13 is engaged with the outer casing 11 via the first engaging portion 116 and the second engaging portion 131. The first engaging portion 116 is a locking block, the tail cover 13 is E-shaped, and the tail cover 13 has a sleeve groove 133. The second engaging portion 131 is a slot 115 formed in the tail cover 13, located on the inner wall of the sleeve groove 133. When the tail cover 13 is fitted onto the outer casing 11 via the sleeve groove 133, the locking block engages with the slot 115 to achieve the engagement between the tail cover 13 and the outer casing 11, facilitating the installation and removal of the male terminal 12 and the tail cover 13.

[0057] Optionally, the outer casing 11 has a second terminal hole 117 and a terminal groove 118 connected in sequence, and the tail cover 13 has a third terminal hole 132. One end of the male terminal 12 passes through the second terminal hole 117, and the other end of the male terminal 12 passes through the third terminal hole 132. The anti-detachment part 121 of the male terminal 12 is located in the terminal groove 118 and is clamped between the tail cover 13 and the inner wall of the terminal groove 118. Specifically, a terminal groove 118 is formed between the two bosses 114. The second terminal hole 117 and the terminal groove 118 are connected in sequence from top to bottom. The signal male terminal 12 is installed from bottom to top into the terminal groove 118 and the second terminal hole 117. The anti-detachment part 121 is located in the terminal groove 118 and is clamped between the tail cover 13 and the inner wall of the terminal groove 118, thereby realizing the installation and anti-detachment of the male terminal 12.

[0058] Meanwhile, this application also provides a connector, including a socket 2 and a plug 1 of any of the above embodiments. The socket 2 and the plug 1 are snapped or plugged into each other. When the socket 2 and the plug 1 are plugged in, the terminal insertion hole on the socket 2 is fitted into the female terminal 15 of the plug 1 and then fitted into the guide platform 151 along the guide ring surface 152.
