Description

Technical Field

[0001] This utility model relates to the field of power connector technology, and in particular to an anti-disconnection power connection device. Background Technology

[0002] With the rise of new energy light transportation vehicles (domestic and international e-bikes, electric scooters, electric tricycles, and ride-hailing vehicles), and the widespread use of low-capacity lithium batteries, various signal connectors for vehicle systems are also increasing. These connectors typically have at least two terminals to enable signal transmission between various electronic components. In vehicle applications, a male or female connector harness from one electronic component is usually connected to a male or female connector harness from another electronic component.

[0003] Because new energy mobility vehicles inevitably encounter bumpy roads during operation, existing connectors may detach during use due to the bumpy ride, posing a safety hazard to vehicle users. Utility Model Content

[0032] Example

[0033] Please see Figures 1 to 7 As shown, this embodiment provides an anti-detachment power connection device, which includes a matching connector 1 and a connector 2. The connector 1 is provided with a first mating member 3, and the first mating member 3 has a first mating cavity 31. The first mating cavity 31 is provided with at least three power terminals 32 and multiple signal terminals 33. The connector 2 is provided with a second mating member 4, and the second mating member 4 has a second mating cavity 41. The second mating cavity 41 is provided with a connector 42. The connector 42 has multiple power sockets 43 and signal sockets 44 corresponding to the power terminals 32 and signal terminals 33. The mating end of the first mating member 3 is provided with a first anti-detachment protrusion 34, and the mating end of the second mating member 4 is provided with a second anti-detachment protrusion 45. The second anti-detachment protrusion 45 is at least configured to form a limiting channel with the outer wall of the connector 42 to allow the first anti-detachment protrusion 34 to pass through.

[0034] Specifically, the diameters of connector 1 and connector 2 are less than 6mm.

[0035] Optionally, the first docking cavity 31 is provided with three power terminals 32 and six signal terminals 33.

[0036] As can be seen, the second anti-detachment protrusion 45 and the outer wall of the connector 42 form a limiting channel through the first anti-detachment protrusion 34, and the second anti-detachment protrusion 45 limits the first anti-detachment protrusion 34 passing through the limiting channel, preventing the connection between the connector 1 and the connector 2 from falling off.

[0037] In one embodiment, the first anti-detachment protrusion 34 is annularly sleeved on the mating end of the first mating member 3, and the first anti-detachment protrusion 34 and the first mating member 3 are integrally formed.

[0038] Specifically, the first anti-detachment protrusion 34 has a first chamfer 340 at both ends along the length of the first mating member 3.

[0039] In one embodiment, the second anti-detachment protrusion 45 is ring-shaped and sleeved on the docking end of the second docking member 4, and the second anti-detachment protrusion 45 and the second docking member 4 are integrally formed.

[0040] Specifically, the second anti-detachment protrusion 45 has a second chamfer 450 at both ends along the length of the second mating member 4.

[0041] It is evident that the first chamfer 340 and the second chamfer 450 facilitate the installation and connection between the first mating part 3 and the second mating part 4, thereby improving installation efficiency.

[0042] In one implementation, the mating ends of the power terminal 32 and the signal terminal 33 are lower than the bottom of the first anti-detachment protrusion 34.

[0043] In one embodiment, the first mating part 3 is provided with a foolproof protrusion 5, and the mating joint 42 is provided with a foolproof notch 6 that matches the foolproof protrusion 5.

[0044] It can be seen that by setting the ends of the power terminal 32 and the signal terminal 33 to be no higher than the bottom of the first anti-detachment protrusion 34, and in conjunction with the anti-fooling protrusion 5 and the anti-fooling notch 6, the installation efficiency of the connector 1 and the connector 2 during connection is higher, and wear on the power terminal 32 and the signal terminal 33 can be avoided when adjusting the mating position of the connector 1 and the connector 2.

[0045] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0046] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above examples.
