Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a high-voltage connector which is convenient to plug and unplug. Background Technique

[0002] A connector is an electrical component. Some of its technical indicators are similar to those of a switch, such as contact resistance, insulation resistance, withstand voltage, torque, and service life. Generally, the service life of a connector is much lower than that of a switch, but its contact reliability should be much higher than that of a switch. A connector consists of two parts, namely a plug and a socket, and they can generally be completely separated under normal conditions. The similarity between a switch and a connector is that they both achieve the purpose of converting the connected circuit by changing the contact state of their contact pairs. The essential difference is that a connector only has two states: inserted and unplugged, while a switch can achieve circuit conversion on its own body, but a connector cannot achieve conversion on its own body, and there is a fixed corresponding relationship between the contact pairs of a connector.

[0003] At present, when the plug and the socket of a connector are plugged, although the sealing ring provided for plugging and closing between the plug and the socket can achieve plugging and sealing, when the plug of the connector is not firmly plugged into the socket, it is easy for the plug and the socket to be affected by external interference, such as traction, resulting in unstable plugging and unplugging of the connector, inconvenient plugging and unplugging, and poor sealing and waterproof performance of the plugging.

The waterproof retaining platform 3 is arranged inside the waterproof clamping groove 4. Positioning seats 5 are provided at the lower ends of the opposite sides of the second plug socket 2, and positioning plates 6 are provided at the opposite sides of the first plug socket 1. The positioning plates 6 and the positioning seats 5 are connected by a clamping mechanism to realize the clamping positioning and plugging and unplugging of the plug-in connector. The plugging and unplugging operation is convenient and the plugging is firm. The waterproof retaining platform 3 is hermetically arranged in the waterproof clamping groove 4 to enhance the sealing and waterproof performance of the plug-in connection of the plug-in connector.

[0024] Specifically, the clamping mechanism includes a groove 51, a second spring 52, a positioning block 53 and a positioning hole 61. Grooves 51 are provided on both opposite sides of the positioning seat 5 below the second socket 2. A positioning block 53 is provided in the groove 51 through a second spring 52. A positioning hole 61 is provided on the positioning plate 6. The positioning block 53 is arranged in the positioning hole 61. When the second socket 2 is fully inserted and fitted with the first socket 1, the positioning block 53 on the positioning seat 5 coincides with the positioning hole 61 on the positioning plate 6, and the positioning block 53 is clamped in the positioning hole 61, and the connectors are inserted and combined.

[0025] Further, two positioning plates 6 are provided on each side of the first socket 1. The distance between the two positioning plates 6 corresponds to the width of the positioning seat 5. The positioning seat 5 is tightly inserted between the two positioning plates 6 for positioning and fixing, and the positioning and clamping structure is compact and stable.

[0026] Further, a waterproof inclined surface 31 is provided on the side of the waterproof retaining platform 3 away from the plug connector 7. The side of the waterproof inclined surface 31 away from the plug connector 7 is inclined downward. The waterproof clamping groove 4 has the same structure as the waterproof inclined surface 31, being lower outside and higher inside, and the plugging and drainage performance is good.

[0027] Further, the waterproof retaining platform 3 is made of high-strength waterproof rubber. A buffer cavity 32 is provided inside the waterproof retaining platform 3 above the waterproof inclined surface 31. A first spring 33 is provided inside the buffer cavity 32, and the waterproof retaining platform 3 has good buffer elasticity.

[0028] Further, the positioning seat 5 above the positioning block 53 is arranged in an inclined surface, and the lower end of the positioning block 53 is arranged in an inclined surface, which facilitates the insertion between the positioning block 53 and the positioning hole 61 on the positioning plate 6.

[0029] Furthermore, the height of the plug connector 7 corresponds to the depth of the plugging groove 8. Plugging pins are provided inside the plugging groove 8, and plugging holes corresponding to the plugging pins are provided on the plug connector 7. The plugging pins are inserted and removed in the plugging holes, and the plug connector 7 and the plugging groove 8 are tightly plugged.

[0030] The method of using this embodiment is as follows: plug the No. 2 socket 2 into the No. 1 socket 1, so that the plug connector 7 on the No. 1 socket 1 is inserted into the plug slot 8 of the No. 2 socket 2, and the plug pin in the plug slot 8 is plugged into the plug hole on the plug connector 7. At the same time, the waterproof baffle 3 on the No. 1 socket 1 is plugged into the waterproof card slot 4 of the No. 2 socket 2, and the positioning seat 5 is inserted between the two positioning plates 6. When the No. 2 socket 2 and the No. 1 socket 1 are fully plugged and fitted, the positioning block 53 on the positioning seat 5 coincides with the positioning hole 61 on the positioning plate 6, and the positioning block 53 is snapped into the positioning hole 61. The connector is plugged into the assembly, and the positioning block 53 in the positioning hole 61 is pressed. The No. 2 spring 52 is compressed, and the positioning block 53 is pressed into the groove 51. At the same time, the No. 1 spring 33 in the buffer cavity 32 on the waterproof baffle 3 is elastically supported, so that the No. 2 socket The socket 2 is elastically pushed away from the No. 1 socket 1, so that the positioning block 53 on the positioning seat 5 is staggered with the positioning hole 61 on the positioning plate 6, and the No. 2 socket 2 is pulled out from the No. 1 socket 1 to realize the card-connected positioning and plug-in and plug-in of the connector. The plug-in and plug-in operation is convenient and the plug-in and plug-in are stable. The waterproof baffle 3 is sealed in the waterproof card slot 4 to enhance the sealing and waterproof properties of the connector plug-in. The waterproof inclined surface 31 on the waterproof baffle 3 is low on the outside and high on the inside, and has good plug-in drainage properties, reducing the probability of water seepage at the plug-in location of the connector. The buffer cavity 32 and the No. 1 spring 33 arranged on the waterproof baffle 3 made of high-strength waterproof rubber material make the waterproof baffle 3 have good buffering elasticity. Therefore, when the No. 2 socket 2 is plugged into the No. 1 socket 1, the waterproof baffle 3 is compactly plugged into the waterproof card slot 4, and the plug-in sealing and waterproof properties are better, and it is convenient to position and plug-in and pull-out of the connector.
