Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a sealing technology detection device for automobile connectors. Background Art

[0002] Automotive connectors are crucial components in automotive electronics systems, connecting and transmitting power and signals. Modern automotive connectors primarily consist of plugs and sockets, which connect to each other to transmit data and signals. The connectors typically utilize a sealed snap-fit connection, which reduces the risk of water and dust intrusion and improves the connection's conductivity. During production, automotive connectors require sealing testing to prevent water and dust from leaking at the connector interface. Consequently, the plugs and sockets must be placed on a sealing tester for alignment testing.

[0003] However, when detecting the sealing effect of the plug and socket, the common automotive connector sealing technology detection device needs to wrap the sealing mold on the outside, which causes resource waste and affects the detection efficiency. Moreover, if the plug is not positioned, it is easy to affect the sealing detection work. In view of this, we propose a sealing technology detection device for automotive connectors.

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example

[0022] like Figures 1 to 3 As shown, the utility model proposes a device for detecting sealing technology of automobile connectors, including a pressure-resistant sealing box 1 and a plug, a pressure valve gauge 2 fixedly mounted on the top wall of the pressure-resistant sealing box 1, which is beneficial for detecting the sealing performance of the pressure-resistant sealing box 1, and a pressure reducing valve 8 fixedly mounted in a discharge port opened on the other side wall of the pressure-resistant sealing box 1, which is beneficial for adjusting the pressure in the pressure-resistant sealing box 1 according to the sealing detection requirements, a bracket 4 fixedly mounted on one side wall of the pressure-resistant sealing box 1, and an air pump 3 fixedly mounted on the top wall of the bracket 4, and the bracket 4 supports the air pump 3. The outlet end of 3 is connected with the interior of the pressure-resistant sealing box 1, which is convenient for the subsequent cooperation with the pressure-resistant sealing box 1 and the pressure valve meter 2 to detect the sealing performance of the plug; a positioning assembly 5 is installed on the side wall of the bracket 4, and the positioning assembly 5 includes an auxiliary box 51, an internal threaded barrel 52 and a sealing ring 53. The opening side of the auxiliary box 51 is fixedly mounted on one side wall of the bracket 4, and one end of the internal threaded barrel 52 is arranged in a first through hole opened on the side wall of the auxiliary box 51. Part of the outer ring surface of the internal threaded barrel 52 is fixedly connected to the hole wall of the first through hole, and the sealing ring 53 is fixedly sleeved on the outer ring surface of the internal threaded barrel 52.

[0023] Furthermore, a connection assembly 6 is installed on the positioning assembly 5 to facilitate sealing detection of the plug. The connection assembly 6 includes a socket 61, an external threaded barrel 62 and a sealing insert ring 63. One end of the external threaded barrel 62 is fixedly connected to the back wall of the socket 61, and the other end of the external threaded barrel 62 passes through the internal threaded barrel 52, and its other end is inserted into the auxiliary box 51. The external threaded barrel 62 and the internal threaded barrel 52 are connected by threads, so that the socket 61 is fixedly installed on the auxiliary box 51, which makes it convenient to insert the plug into the socket 61. After the air pump 3 drives and reduces pressure, the pressure valve gauge 2 cooperates with the pressure-resistant sealing box 1 to realize the sealing detection of the plug and the socket 61. Under the action of negative pressure, there is no need to position the plug separately, thereby achieving the purpose of limiting and reducing the operating steps. At the same time, it is beneficial to improve the detection efficiency. The sealing insert ring 63 is fixedly sleeved on the outer ring surface of the external threaded barrel 62. During the plug-in process of the external threaded barrel 62, the sealing insert ring 63 can be inserted into the end of the internal threaded barrel 52, and the sealing ring 53 is used to block the socket 61. After the installation is completed, the sealing of the connection between the external threaded barrel 62 and the internal threaded barrel 52 is improved, reducing the risk of air leakage. Conversely, the socket 61 can be rotated so that the external threaded barrel 62 can be disassembled and replaced with the assistance of the internal threaded barrel 52, so that the user can adjust the socket 61 to match it according to the size of the plug, and install and replace it through the threaded connection relationship between the external threaded barrel 62 and the internal threaded barrel 52, thereby improving the applicability of this equipment and reducing the impact of the plug size limitation.

[0024] Furthermore, the auxiliary box 51 is provided with a positioning sealing assembly 7 for reinforcing and sealing the connection assembly 6. The positioning sealing assembly 7 includes a bidirectional threaded rod 71, an L-shaped movable seat 72, an arc-shaped sealing clamp 73, a guide rod 74 and a bearing seat 75. A second through hole is opened on the front wall of the auxiliary box 51, and a sealing bearing is arranged in the second through hole. The bearing seat 75 is fixedly installed on the inner surface wall of the auxiliary box 51. The end of the bidirectional threaded rod 71 passes through the second through hole and the threaded hole on the L-shaped movable seat 72 and is connected to the rotating end of the bearing seat 75, which is conducive to the rotation of the bidirectional threaded rod 71 with the assistance of the bearing seat 75. At the same time, the inner ring surface of the sealing bearing is also connected to part of the outer ring surface of the bidirectional threaded rod 71, which facilitates the sealing of the second through hole while assisting it to rotate, thereby reducing Low risk of air leakage; the two ends of the guide rod 74 are fixedly connected to the inner walls of the two sides of the auxiliary box 51, and are arranged in the sliding holes symmetrically opened on the two L-shaped movable seats 72. The cooperation between the sliding holes and the guide rod 74 is conducive to driving the two L-shaped movable seats 72 to move in the same direction or reverse direction during the rotation of the two-way threaded rod 71, which is convenient for adjusting their positions. The side walls of the two arc-shaped sealing clamps 73 are fixedly connected to the ends of the two L-shaped movable seats 72, so that the two L-shaped movable seats 72 can drive the two arc-shaped sealing clamps 73 to clamp the external threaded tube 62 during the movement. At the same time, after the two arc-shaped sealing clamps 73 are spliced, the purpose of sealing and positioning the plug-in joint of the external threaded tube 62 is achieved, reducing the risk of the connection component 6 being loose during the detection process, and providing convenience for subsequent sealing detection work.
