Description

Technical Field

[0001] This utility model proposes a connection component, and more particularly a warehouse robot connection component with high insertion and removal life, low insertion and removal force, and low contact resistance. Background Technology

[0002] In automated warehousing and logistics systems, robots (such as AGVs and AMRs) need to frequently perform automatic charging or data interaction, and their connecting components need to withstand tens of thousands of plug-and-unplug operations. Traditional connectors have the following problems:

[0003] 1. Excessive insertion and extraction force may cause the robot docking mechanism to have excessively high positioning accuracy requirements or make docking difficult;

[0004] 2. The plug-in life is limited. After repeated use, the terminals wear down, leading to increased contact resistance or even failure, which affects charging efficiency or data transmission stability.

[0005] Therefore, there is an urgent need for a connection component that can ensure low insertion and extraction force, easy docking, and achieve extremely long insertion and extraction life and stable low contact resistance. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a warehouse robot connection component that features high insertion / removal life, low insertion / removal force, and low contact resistance.

[0007] To achieve the above objectives, this utility model provides a connection component for a warehouse robot, comprising a plug and a socket; wherein, The plug portion includes a first housing, a floating pin terminal, a second housing, and a connector; the first housing and the second housing are connected by the connector to clamp the floating pin terminal within the first housing and the second housing; The socket includes a first base, a crown spring terminal, a second base, and a connecting wire; wherein the connecting wire passes through the second base and is fixed to the tail of the crown spring terminal; the first base and the second base are combined, and the crown spring terminal is clamped in the first base and the second base; the crown spring terminal is a cylindrical structure composed of multiple elastic metal beams; During connection, the first base is aligned with the second housing, and the floating pin terminal can be inserted into the crown spring terminal, contacting the multiple elastic metal beams of the crown spring terminal respectively.

[0008] Furthermore, there is a gap between the floating pin terminal and the terminal hole of the first housing and / or the second housing to create a floating effect in the radial direction.

[0009] Furthermore, the first base is combined with the second base by ultrasonic welding.

[0010] Furthermore, the first base and the second outer shell are connected by a guide structure.

[0011] Furthermore, the guide structure includes a guide groove disposed on the first base and a guide protrusion disposed on the second housing.

[0012] Furthermore, the connector includes a nut and a screw; wherein the nut is embedded in the second housing, and the screw passes through the first housing and engages with the nut.

[0013] Furthermore, the crown spring terminal is made of beryllium bronze.

[0014] Furthermore, the tail end of the crown spring terminal is provided with a crimping structure for riveting the connecting wire.

[0015] The warehousing robot connection assembly provided by this utility model uses a floating terminal at the plug end and a crown spring terminal with multiple elastic metal beams at the socket end. During docking, due to the multi-beam design of the crown spring terminal, the pressure per unit area is moderate, the wear is extremely low, and the life of insertion and removal can be achieved for tens of thousands of times. In addition, multiple parallel contact points provide redundant current paths, the contact resistance is low and stable, and the risk of excessive temperature can be avoided.

[0019] Figure 4 This is a schematic diagram of the guide structure of the plug and socket parts in this utility model. Detailed Implementation

[0020] like Figures 1 to 4 As shown, the warehouse robot connection assembly provided by this utility model includes a plug part 1 and a socket part 2.

[0021] The plug part 1 includes a first housing 101, a floating pin terminal 102, a second housing 103, a housing pre-embedded nut 104, and a housing connecting screw 105. Both the first housing 101 and the second housing 103 are provided with terminal holes, and the two ends of the floating pin terminal 102 can be inserted into the terminal holes of the first housing 101 and the second housing 103 respectively. The housing pre-embedded nut 104 is pre-embedded in a slot in the first housing 101. After the two ends of the floating pin terminal 102 are inserted into the terminal holes of the first housing 101 and the second housing 103 respectively, the first housing 101 and the second housing 103 are aligned. The housing connecting screw 105 is then passed through the second housing 103 and screwed into the housing pre-embedded nut 104 in the first housing 101 to lock them in place, thus achieving the connection between the first housing 101 and the second housing 103.

[0022] Here, the floating pin terminal 102 is not fixed inside the first housing 101 and the second housing 103, but has a radial gap with the terminal hole of the first housing 101 and the second housing 103. Using this gap, the floating pin terminal can float in the radial direction, thereby automatically compensating for the small deviations that exist in the robot docking process during insertion, and avoiding wear caused by pin jamming or misalignment.

[0023] In this embodiment, the first outer shell 101 and the second outer shell 103 are connected by a pre-embedded nut 104 and a connecting screw 105. Of course, other connection methods or connectors can also be used to achieve the connection, such as locking buckles or riveting. No further restrictions are imposed here.

[0024] The socket part 2 includes a first base 201, a crown spring terminal 202, a second base 203, and a connecting wire 204.

[0025] The crown spring terminal 202 includes a head and a tail. The tail of the crown spring terminal 202 can be disposed in the terminal hole of the second base 203, and the head is disposed in the terminal hole of the first base 201. Preferably, the head of the crown spring terminal 202 is a cylindrical structure composed of multiple elastic metal beams. When the multiple elastic metal beams contact the floating pin terminal 102, they can each form an independent contact point. Preferably, the crown spring terminal 202 is made of a high-performance elastic material such as beryllium bronze.

[0026] The connecting wire 204 passes through the second base 203 and is fixed to the tail of the crown spring terminal 202; the conductor part of the connecting wire 204 is inserted into the crimping structure at the tail of the crown spring terminal 202, and a reliable electrical and mechanical connection is formed by crimping with a crimping tool.

[0027] The second base 203 is combined with the first base 201, and the crown spring terminal 202 is clamped within the first base 201 and the second base 203. When the second base 203 is combined with the first base 201, an ultrasonic welding process is used to fuse them into a sealed, high-strength whole, encapsulating the crown spring terminal 202 inside.

[0028] Furthermore, the warehouse robot connection assembly is also equipped with a guide structure for aligning and connecting the plug part 1 and the socket part 2. For example... Figure 4 As shown, the second housing 203 of the plug portion 1 is provided with a guide protrusion 4, and the first base 201 of the socket portion 2 is provided with a matching guide groove 5. During docking, the guide structure ensures initial guidance and alignment.

[0029] The warehouse robot connection assembly provided by this utility model includes the following components during insertion:

[0030] First, the robot drive mechanism pushes the plug part 1 towards the socket part 2, and the guide protrusion 4 on the second housing 203 is inserted into the guide groove 5 of the first base 201 to achieve coarse positioning docking.

[0031] Next, the plug portion 1 continues to advance, and the floating pin terminal 102 begins to insert into the inner hole of the crown spring terminal 202. If there is a slight alignment error, the floating pin terminal 102 can adaptively adjust using its floating gap to ensure smooth insertion. When the floating pin terminal 102 is fully inserted, the multiple elastic metal beams 2021 of the crown spring terminal 202 undergo elastic deformation, uniformly wrapping around the pin surface to form multiple stable linear contact points. Since each beam forms line contact with the surface of the floating pin terminal 102, multiple parallel current paths are formed. This design greatly reduces contact resistance, and even if individual contact points fail due to contamination or wear, other contact points can still ensure a smooth connection, significantly improving reliability. In addition, multi-point contact also allows the insertion and extraction force to be evenly distributed, thereby achieving a smooth, low-force insertion and extraction feel while ensuring sufficient contact positive pressure.

[0032] Based on the above, the beneficial effects of the warehouse robot connection component provided by this utility model are as follows: 1. Low insertion and extraction force, long life: The multi-beam design of the crown spring terminal provides moderate pressure per unit area and extremely low wear, enabling a insertion and extraction life of tens of thousands of cycles. 2. Low contact resistance and high reliability: Multiple parallel contact points provide redundant current paths, resulting in low and stable contact resistance and avoiding the risk of overheating. 3. High tolerance: The floating pin design effectively absorbs installation and docking errors, improving docking success rate and adaptability. 4. Robust and durable: Ultrasonic welding and screw locking ensure the overall mechanical strength of the components, excellent vibration resistance, high contact reliability in harsh environments such as dust, and are suitable for industrial environments.

[0033] 5. Easy maintenance: The plug and socket can be replaced separately in a modular fashion, reducing maintenance costs and time.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of the present utility model.
