Description

Technical Field

[0001] The utility model relates to the technical field of airtightness testing, and particularly relates to a portable airtightness testing tooling for a 70-square high-voltage connector. Background Technique

[0002] With the continuous improvement of living standards and the enhancement of energy conservation and emission reduction awareness, more and more people travel by new energy electric vehicles, which have the advantages of convenient travel, energy conservation and environmental protection. In the field of new energy electric vehicles, the core system includes a high-voltage box, a control box and a battery pack to form the core power system of the electric vehicle. In the airtightness testing process of the high-voltage box workshop, for the airtightness testing of the 70-square high-voltage connector, 6 M4*12 bolts need to be installed and tightened on the airtight upper cover, and the bolts need to be disassembled after the test, so the airtightness testing cannot be carried out quickly and efficiently. The utility model provides a portable airtightness testing tooling for a 70-square high-voltage connector. Content of the Utility Model

[0003] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a portable airtightness testing tooling for a 70-square high-voltage connector, with a reasonable structural design. After adopting this testing tooling, there is no need to lock the bolts, it is more convenient and reliable to use, the passing rate of airtightness testing is high, the production rhythm is improved, and the working intensity of on-site workers is reduced.

[0004] In order to achieve the above purpose, the utility model is realized by the following technical scheme: a portable airtightness testing tooling for a 70-square high-voltage connector, including an airtight tooling main body, an airtight gasket and a guide post. Guide posts are arranged on both sides inside the airtightness tooling main body, and an airtight gasket is arranged inside the inner ring of the guide post.

[0005] Preferably, six guide posts are provided, which are respectively arranged on the inner side of the airtight tooling main body, three on each side, and the guide posts are aligned with six hole positions on the 70-square high-voltage connector.

[0006] Preferably, the airtight gasket is made of a rubber ring and has a sealing effect.

[0007] Advantages of the utility model: The guide posts of the utility model are used to align six hole positions on the 70-square high-voltage connector to achieve quick and accurate positioning; the airtight gasket is used to prevent insufficient airtightness during the airtightness testing and plays a sealing role; the airtight tooling main body is used for employees to quickly plug and unplug. The utility model can achieve quick installation, a high passing rate of on-site airtightness testing, improve the production rhythm, and reduce the working intensity of on-site workers. Description of the Drawings

[0008] The following will describe the utility model in detail with reference to the drawings and specific embodiments;

[0009] Figure 1It is a schematic structural diagram of the present utility model;

[0010] Figure 2 It is an exploded schematic diagram of the present utility model. Specific embodiments

[0011] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0012] Refer to Figure 1-2 , the following technical solutions are adopted in this specific embodiment: a portable airtight test tooling for a 70-square high-voltage connector, including an airtight tooling main body 1, an airtight gasket 2 and a guide post 3. Guide posts 3 are arranged on both sides inside the airtight tooling main body 1, and an airtight gasket 2 is arranged inside the inner ring of the guide post 3.

[0013] It should be noted that six guide posts 3 are provided, which are respectively arranged inside the airtight tooling main body, with three on each side. The guide posts 3 are aligned with six hole positions on the 70-square high-voltage connector.

[0014] In addition, the airtight gasket 2 is made of a rubber ring and has a sealing effect.

[0015] In order to efficiently and quickly carry out the airtight test process in the high-voltage box assembly line workshop, this specific embodiment adopts the structures of the airtight gasket 2 and the guide post 3. The guide post is used to align six hole positions on the 70-square high-voltage connector to achieve rapid and accurate positioning; the airtight gasket is used to prevent insufficient airtightness during the airtight test and plays a sealing role; the airtight tooling main body is used for employees to quickly plug and unplug.

[0016] This specific embodiment can achieve fast installation, a high passing rate of on-site airtight tests, improve the production rhythm, and reduce the work intensity of on-site workers.

[0017] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
