Description

High-tightness wire harness connector Technical Field The utility model belongs to the field of automobile wire harness parts, and particularly relates to a high-tightness wire harness connector. Background In the design of a traditional wire harness connector, the traditional connector is usually filled with rubber sealing rings or glue to realize dust prevention and water prevention, and is easy to age and crack after long-term use, so that sealing failure is caused, a gap exists between a wire harness and an interface due to the fact that an elastic compression structure is uniformly distributed in a common connector, water vapor and dust are easy to infiltrate, and technical bottlenecks exist under the sealing performance, so that the connector is easy to fail under severe environments. Disclosure of utility model In view of the above, the technical problem to be solved by the present utility model is to provide a high-tightness harness connector. The first limiting ring, the second limiting ring, the elastic pressing blocks and the first limiting ring are uniformly distributed, the joint is tightly attached, invasion of external pollutants such as water vapor and dust is effectively prevented, and external elastic fixing bands are additionally arranged through the buckle design of the limiting grooves and the limiting blocks, double limiting is achieved, and external movement is further avoided. In order to solve the technical problems, the utility model discloses a high-tightness wire harness connector which comprises a first wire harness connector, wherein a second wire harness connector is inserted to the right side of the first wire harness connector, a semicircular first limiting ring is arranged at the joint of the first wire harness connector and the second wire harness connector, the bottom of the first limiting ring is connected with a second limiting ring, a limiting groove is arranged at the bottom of the first limiting ring, a limiting block corresponding to the limiting groove is arranged on the second limiting ring, elastic pressing blocks with uniform intervals are arranged in the first limiting ring and the second limiting ring, clamping grooves corresponding to each other are arranged outside the first limiting ring and the second limiting ring, and elastic fixing belts are arranged in the clamping grooves. According to an embodiment of the present utility model, the first limiting ring and the second limiting ring are clamped and connected by a limiting groove and a limiting block. According to an embodiment of the present utility model, the number of the clamping grooves is three. According to an embodiment of the present utility model, the number of the elastic pressing blocks is 18. Compared with the prior art, the utility model can obtain the following technical effects: 1) The first limiting ring, the second limiting ring, the elastic pressing blocks and the first limiting ring are uniformly distributed, the joint is tightly attached, invasion of external pollutants such as water vapor and dust is effectively prevented, and external elastic fixing bands are additionally arranged through the buckle design of the limiting grooves and the limiting blocks, double limiting is achieved, and external movement is further avoided. Of course, it is not necessary for any one product embodying the utility model to achieve all of the above technical effects simultaneously.
