Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a high-voltage resistant connector with a secondary lock. Background Art

[0002] In China, it is also called a connector and a socket, which generally refers to an electrical connector. That is, a device that connects two active devices to transmit current or signals. The male end and the female end can transmit information or current after contact, which is also called a connector.

[0003] In an existing connector, there is no isolation barrier between the female groove electrodes and they are densely distributed, so the high-voltage resistance is poor. When the connector is in a humid environment or invaded by hygroscopic impurities such as hygroscopic dust, free gas or salts, the creepage distance of the connector shell will be greatly reduced, and leakage is likely to occur between the connector electrodes, affecting the normal use of the equipment. Summary of the invention

[0004] The utility model aims to provide a high-voltage resistant connector with a secondary lock.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] It comprises a male end and a female end which are arranged to be interlocked and locked with each other, the male end is provided with a plurality of interlocking protrusions, the female end is provided with an interlocking groove which matches the interlocking protrusions, an electrode column is fixedly installed in the interlocking groove, an electrode port for the electrode column to pass through is provided near the end of the interlocking protrusion, a wire groove which is connected to the electrode port is provided in the interlocking protrusion, a wire clamp for clamping the electrode column is clamped and installed in the wire groove, insulating grooves are arranged between adjacent interlocking grooves, an insulating rubber block which is interlocked with the insulating groove is provided at the male end, an elastic rubber ring which surrounds the electrode port is fixedly provided on one side of the interlocking protrusion close to the interlocking groove, and a sealing groove which matches the elastic rubber ring is provided in the interlocking groove.

[0007] By adopting the above technical scheme, insulating grooves and insulating rubber blocks are provided between adjacent electrode columns, which play a good barrier role. On the one hand, the spacing between the electrode columns can be increased to prevent high-voltage leakage. On the other hand, the shortest distance between the electrode columns is blocked to increase the travel of the leakage current, thereby improving the overall insulation. The elastic rubber ring and the sealing groove are combined to effectively improve the overall sealing effect of the connector. The insulating rubber block fills and blocks the insulating groove with good static friction. The male end and the female end are not easy to fall off under the action of external force. It can also prevent water-absorbed impurities and external water vapor from entering the insulating groove and the electrode column. The connector joint can withstand higher voltages and avoid water ingress and leakage.

[0008] Furthermore, a side of the male end away from the female end is provided with a wire opening connected to the wire groove, the wire clamp is made of metal and is slidably arranged on the wire groove along the length direction, the second buckle is installed on the top wall of the male end, the second buckle is inserted into the wire groove and is provided with a pair of first clamping plates, the end of the first clamping plate is provided with double clamping protrusions, and the top wall of the wire clamp is provided with a three-level clamping slot matching the double clamping protrusions.

[0009] By adopting the above technical scheme, the three-level slot is provided with three slots in sequence along the length direction of the wire clamp. After the wire clamp is installed with the wire, it is inserted into the wire slot. The double-engaging protrusions will first engage with the first two slots to fix the wire slot, so as to facilitate the smooth insertion of the electrode column. When the electrode column is too long and has poor contact, the wire clamp is pushed again to make the last two slots engage with the double-engaging protrusions for the second time. The wire clamp is further moved toward the direction of the electrode port to make the electrode column and the wire clamp well combined to prevent poor contact. At the same time, the wire clamp is more tightly combined with the male end under the secondary tightening of the second buckle, and is not easy to fall off. After removing the second buckle, the three-level slot and the double-engaging protrusion can be unlocked, so as to facilitate the replacement of the wire.

[0010] Furthermore, a first engaging ridge is fixedly provided on the outer side wall of the engaging protrusion, a first engaging groove is penetrated by the engaging groove for the first engaging ridge to engage and lock, a pair of second engaging plates are extended from one side of the outer wall of the male end of the second fastener, and a second engaging groove is penetrated by the male end to cooperate with the second engaging plate.

The connector as a whole is clamped and fastened one by one, and the integrity is enhanced. When in use, the various components are not easy to fall off and have good stability. At the same time, it is also convenient for subsequent unlocking. The first engaging ridge or the second engaging plate can be knocked out of the corresponding slot with a hard object.

[0012] Furthermore, a wire welding portion is fixedly provided at one end of the wire clamp near the wire opening, a pair of inwardly retracted elastic metal sheets are extended from one end of the wire clamp near the electrode opening, a minimum spacing between the elastic metal sheets is smaller than the diameter of the electrode column, an open metal sheet is extended from the end of the elastic metal sheet, a first socket larger than the diameter of the electrode column is provided at intervals between the open metal sheets, an extension plate longer than the elastic metal sheet is extended from one end of the wire clamp near the electrode opening, a guide plate covering the first socket is fixedly provided at the end of the extension plate, and the guide plate passes through a second socket provided to match the electrode column.

[0013] By adopting the above technical solution, the wire welding part has an uneven structure to facilitate wire winding and welding. The elastic metal sheets have a small spacing and can be clamped on the surface of the electrode column to maintain a good electrical connection when the electrode column is inserted. The setting of the first socket and the second socket limits the movement direction of the electrode column in the horizontal and vertical directions, ensuring that the electrode column can be stably inserted between the elastic metal sheets along a predetermined route, with a good guiding effect.

[0014] Furthermore, a conductor sheet passing through the female end is fixedly provided at one end of the female end electrode column, the female end is provided with a sheet-shaped groove for sliding installation of the conductor sheet, a plurality of barbed third engaging ridges are fixedly provided on the outer wall of the conductor sheet, the sheet-shaped groove is provided with a third engaging groove matching the third engaging ridges, the sheet-shaped groove wall is provided with regular triangular protrusions, and the conductor sheet is provided with a triangular groove matching the triangular protrusions.

[0015] By adopting the above technical solution, the barbed third engaging ridge cooperates with the third engaging groove to have a good locking effect, effectively preventing the electrode column from falling off the female end. At the same time, the triangular protrusion cooperates with the triangular groove to further lock the electrode column and the female end, and has good connection stability.

[0016] In summary, the beneficial technical effects of the utility model are:

[0017] 1. Insulation grooves, insulating rubber blocks, elastic rubber rings and sealing grooves are used to increase the spacing between electrode columns to prevent high voltage leakage, increase the travel of leakage current, and thus improve the overall insulation, prevent water-absorbed impurities and external water vapor from entering the insulation grooves and electrode columns, and the connector joint can withstand higher voltages to avoid water ingress and leakage;

[0018] 2. The second buckle, double snap-fit ​​convex, wire clamp and three-level slot are used to make the electrode column and the wire clamp well combined to prevent poor contact.

[0019] 3. The elastic metal sheet, the first socket and the second socket are used, so that the electrode column can be stably inserted between the elastic metal sheets along a predetermined route while maintaining a good electrical connection. BRIEF DESCRIPTION OF THE DRAWINGS
