Abstract
Description
Technical Field
[0001] This application relates to the field of marine engineering equipment technology, specifically to a fixture and testing device for testing the airtightness of connectors. Background Technology
[0002] After the connector's connecting ends (used to connect signal lines) are sealed with adhesive, an airtightness test is required. During the test, a clamp is needed to secure the connector.
[0003] Because connectors vary in type and specification, their dimensions also differ. Therefore, each type of connector requires a dedicated fixture for testing, which results in high testing costs and makes the management and maintenance of the fixtures difficult. Summary of the Invention
[0004] To address the aforementioned technical problems, this application provides a fixture and testing device for connector airtightness testing, which can improve the problems of high cost and difficult maintenance caused by the fact that existing connector airtightness testing fixtures can only be used for one type of connector.
[0005] To solve the above-mentioned technical problems, in a first aspect, embodiments of this application provide a fixture for testing the airtightness of connectors, including an upper fixed base, two clamping blocks, and a locking structure;
[0006] The two clamping blocks are disposed on the bottom surface of the upper fixed base and arranged along the first direction. The bottom surfaces of the two clamping blocks are flush, and at least one of them is slidable along the first direction.
[0007] The locking structure is provided on the upper fixed base and is used to lock the slidable clamping block when it moves to the target position.
[0008] Optionally, the clamp has a groove extending along the first direction on the bottom surface of the upper fixing seat;
[0009] The two sliders are disposed in the groove, and their bottom surfaces protrude from the groove;
[0010] The locking structure is disposed on the side wall of the groove.
[0011] Optionally, the clamping block includes a sliding part and a pressing part connected to each other;
[0012] The sliding part is disposed in the groove;
[0013] The pressing part protrudes from the groove, and the inner side of the pressing part is flush with the inner side of the sliding part.
[0014] Optionally, an elastic buffer is provided on the side of the bottom surface of the pressing part away from the inner side surface of the pressing part, and the natural length of the elastic buffer before deformation is less than the height of the connector.
[0015] Optionally, the locking structure includes two threaded holes and two screws;
[0016] The two threaded holes are provided on the side wall of the groove, respectively facing the two clamping blocks;
[0017] The two screws engage with each other and, after being tightened, lock the two clamping blocks.
[0018] Optionally, the top surface of the upper fixing base is provided with a connection hole for connecting an airtightness tester.
[0019] Secondly, embodiments of this application also provide a testing device for connector airtightness testing, including the fixture and airtightness tester as described in the above embodiments;
[0020] The airtightness tester is connected to the fixture and is used to control the fixture to fix the connector and perform an airtightness test.
[0021] As described above, the fixture for connector airtightness testing of this application has two clamping blocks disposed on the bottom surface of the upper fixed base. The bottom surfaces of the two clamping blocks are flush, and at least one is slidable along a first direction. This allows adjustment of the gap between the two clamping blocks. A locking structure is used to lock the slidable clamping block when it moves to the target position. Before conducting the airtightness test, after installing the fixture on the airtightness tester, the positions of the two clamping blocks can be manually adjusted to ensure a suitable gap between them. Specifically, the two clamping blocks should press against the connector while avoiding the pins of the connector's connection end. Since at least one of the two clamping blocks is slidable along the first direction, the gap between the two clamping blocks can be adaptively adjusted when replacing connectors of smaller or larger sizes, without the need to replace with a new dedicated fixture, thus improving efficiency. The fixture of this embodiment is universal, thereby simplifying the management and maintenance of the fixture. Attached Figure Description

These drawings and textual descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation
[0028] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0029] Please see Figure 1 , Figure 1 This is a schematic diagram of an existing connector. The connector 10a includes a plug end 11a and a connecting end 12a. The plug end 11a is connected to a female connector during use. After being sealed with adhesive, the connecting end 12a is used to connect a signal line. Before connecting the signal line, air needs to be injected from the plug end 11a to perform an airtightness test on the connecting end 12a.
[0030] As mentioned above, connectors 10a vary in size due to differences in type and specifications. Therefore, each connector 10a requires a dedicated fixture for testing, resulting in high testing costs and difficulties in fixture management and maintenance. Based on this, this application provides a fixture and testing device for connector airtightness testing.
[0031] Please see Figure 2 , Figure 2 This is a three-dimensional structural diagram of a fixture for connector airtightness testing provided in an embodiment of this application. The fixture may include an upper fixing seat 10, two clamping blocks 20, and a locking structure 30. According to actual usage, the upward-facing surface of the upper fixing seat 10 in the figure is the bottom surface.
[0032] The two clamping blocks 20 are disposed on the bottom surface 11 of the upper fixed base 10 and arranged along the first direction X. The bottom surfaces 201 of the two clamping blocks 20 are flush, and at least one is slidable along the first direction X. That is, one clamping block 20 can be fixed while the other clamping block 20 is slidable, or both clamping blocks 20 can be slidable, thereby adjusting the gap between the two clamping blocks 20. The locking structure 30 is disposed on the upper fixed base 10 and is used to lock the slidable clamping block 20 when it moves to the target position.
[0033] The working principle of the fixture in this embodiment is as follows: Please refer to... Figure 3 , Figure 3 This is a schematic diagram of a fixture in its working state according to an embodiment of this application. Before conducting an airtightness test, after installing the fixture on the airtightness tester, the positions of the two clamping blocks 20 can be manually adjusted to ensure a suitable gap between them. Specifically, the two clamping blocks 20 should press against the connector 10a while avoiding the pins at the connection end of the connector 10a. Since at least one of the two clamping blocks 20 is slidable along the first direction X, the gap between the two clamping blocks 20 can be adaptively adjusted when replacing a smaller or larger connector 10a, without needing to replace it with a new dedicated fixture, thus improving efficiency. The fixture of this embodiment is universal, thereby simplifying the management and maintenance of the fixture.
[0034] It should be noted that the clamping block 20 can be slidably disposed on the bottom surface 11 of the upper fixed base 10 in various ways. For example, a slide rail-slide groove structure can be provided between the bottom surface 11 of the upper fixed base 10 and the top surface of the clamping block 20. Preferably, please refer to [the following text is missing]. Figure 2 and Figure 4 , Figure 4 This is an exploded structural diagram of a clamp provided in an embodiment of this application. The bottom surface 11 of the upper fixing seat 10 is provided with a groove 12 extending along the first direction X. The two clamping blocks 20 are disposed in the groove 12, and the bottom surface 201 of the clamping blocks 20 protrudes from the groove 12. The locking structure 30 is disposed on the side wall 13 of the groove 12.
[0035] In this embodiment, the clamping block 20 is disposed in the groove 12 of the bottom surface 11 of the upper fixing seat 10, and the locking structure 30 is disposed on the side wall 13 of the groove 12, thereby fixing the position of the clamping block 20. The sliding structure of this embodiment is simpler.
[0036] For example, please continue reading Figure 2 and Figure 4The clamping block 20 may include a sliding part 21 and a pressing part 22 connected to each other. The sliding part 21 is disposed in the groove 12; the pressing part 22 protrudes from the groove 12, and the inner surface 221 of the pressing part 22 is flush with the inner surface 211 of the sliding part 21. It should be noted that in this embodiment, the "inner surface" refers to the opposing surface between the two clamping blocks 22. Preferably, the area of the pressing part 22 is smaller than the area of the sliding part 21, which can reduce the amount of material used and reduce the weight of the clamp.
[0037] For example, please continue reading Figure 3 An elastic buffer 23 is also provided on the side of the bottom surface 201 of the pressing part 22 away from the inner side surface 221 of the pressing part 22. The natural length of the elastic buffer 23 before deformation is less than the height of the connector 10a. In this embodiment, when the bottom of the connector 10a is not completely fixed due to an operational error, the connector 10a may pop out when the pressing part 22 moves downward to press down on the connector 10a. At this time, the elastic buffer 23 is located between the pressing part 22 and the fixing seat 200, which can play a buffering role and prevent the pressing part 22 from directly impacting the fixing seat 200 and damaging the clamp or the fixing seat 200.
[0038] For example, please continue reading Figure 2 and Figure 4 The locking structure 30 includes two threaded holes 31 and two screws 32. The two threaded holes 31 are located on the side wall 13 of the groove 12, respectively facing the two clamping blocks 20. The two screws 32 engage with each other and, after tightening, lock the two clamping blocks 20. In application, after adjusting the distance between the two clamping blocks 20, the screws 32 are tightened.
[0039] For example, please continue reading Figure 2 The top surface of the upper fixed base 10 is provided with a connection hole (not shown in the figure). The connection hole is used to connect an airtightness tester. The airtightness tester can control the lifting and lowering of the clamp to press and release the connector.
[0040] This application also provides a testing device for connector airtightness testing. This testing device may include the fixture and airtightness tester described in the above embodiments. The airtightness tester is connected to the fixture and is used to control the fixture to fix the connector and perform an airtightness test. For example, please refer to... Figure 3 The air tightness tester may include a test platform 100, a lower fixed base 200 set on the test platform 100, and after the connector 10a is positioned on the lower fixed base 200, the air tightness tester controls the clamp to descend and press and fix the connector 10a, and then blows air from the plug end (lower end in the figure) of the connector 10a to detect whether the connection end is leaking.
[0041] For the working principle and process of the detection device in this embodiment, please refer to the description of the fixture for connector airtightness testing in the foregoing embodiments of this application, which will not be repeated here.

Specific examples have been used to illustrate the principles and implementation methods of this application. It should be noted that the descriptions of each embodiment in this application have different emphases; parts not described in detail in a particular embodiment can be referred to in the relevant descriptions of other embodiments.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
