Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] The lack of a corresponding airtightness testing device during the processing of contact 10 makes it impossible to effectively monitor defects such as voids and cracks in the product, resulting in an inability to control the quality of contact 10 upon leaving the factory.

[0031] In view of this, the present invention provides a contact airtightness test device, including a packaging component and a water tank. The packaging component includes a cylinder 110 and a cover 120. The cover 120 is used to block the opening of the cylinder 110 to form a sealed space 101, in which the tested part of the contact 10 is contained. The cylinder 110 has an air inlet 111, which is connected to the sealed space 101. The water tank contains liquid, and after the air inlet pipe is connected to the air inlet 111, the packaging component is placed in the liquid.

[0032] The contact airtightness testing device provided by this utility model contains the test part of the contact 10 in a sealed space 101, and introduces gas into the sealed space 101 through the air inlet 111. The encapsulation component is placed in a liquid. When the contact 10 has a corresponding defect that causes the airtightness to fail, the gas escapes from the sealed space 101 and forms bubbles in the liquid, thereby facilitating the determination of whether the contact 10 is qualified and ensuring the quality of the product leaving the factory.

[0033] The following combination Figures 1-4 The structure and shape of the contact airtightness test device provided in this embodiment are described in detail.

[0034] In this embodiment, the liquid contained in the tank can be water, alcohol, gasoline, etc., and can be selected according to the product.

[0035] In this embodiment, the air inlet 111 is provided with a pipe thread to facilitate quick connection with the air pipe connector and ensure airtightness.

[0036] In this embodiment, as Figure 4 As shown, the contact 10 is provided with a stepped surface 11, and the end of the cover 120 connected to the cylinder 110 abuts against the stepped surface 11.

[0037] In this embodiment, the encapsulation assembly also includes a locking nut 150, such as Figure 1 As shown, the locking nut 150 is fitted onto the contact 10 and threadedly connected to the contact 10; the locking nut 150 abuts against the end of the cover 120 opposite to the stepped surface 11. Specifically, the outer circle of the locking nut 150 is provided with a milled flat surface or an external hexagon to facilitate tightening.

[0038] In this embodiment, the encapsulation assembly further includes a first sealing ring 130, which is used to seal the gap between the cap 120 and the cylinder 110. Correspondingly, a first annular groove 121 is provided on the end of the cap 120 that contacts the cylinder 110. The first annular groove 121 is used to install the first sealing ring 130, such as... Figure 1 , Figure 3 As shown.

[0039] In this embodiment, the encapsulation assembly further includes a second sealing ring 140, which is used to seal the gap between the stepped surface 11 and the cover 120. Correspondingly, a second annular groove 122 is provided on the end of the cover 120 that contacts the stepped surface 11, and the second annular groove 122 is used to install the second sealing ring 140.

[0040] The first annular groove 121 and the second annular groove 122 are disposed at the same end of the cover 120, such as Figure 3 As shown.

[0041] In this embodiment, the cover 120 is provided with a through hole 123, and one end of the contact 10 passes through the through hole 123 and the stepped surface 11 abuts against the cover 120.

[0042] In this embodiment, the cylinder 110 and the cover 120 are detachably connected. Specifically, the cylinder 110 and the cover 120 are connected by screws. The cylinder 110 has a threaded hole 112, and the cover 120 has a through hole 124. The screw passes through the through hole 124 and is inserted into the threaded hole 112.

[0043] In this embodiment, the number of threaded holes 112 and through holes 124 are the same and correspond one-to-one. At least two threaded holes 112 are evenly distributed around the axis of the cylinder 110, and the same number of through holes 124 are evenly distributed around the axis of the cover 120.

[0044] In this embodiment, the inner wall of the cylinder 110 does not contact the contact 10 to ensure sufficient testing of the portion of the contact 10 being tested, and to prevent defects, cracks, or other defects from being sealed off by the cylinder 110 due to contact between the inner wall of the cylinder 110 and the contact 10. Specifically, the inner diameter of the cylinder 110 is larger than the outer diameter of the contact 10, and the depth is greater than the length of the portion of the contact 10 being tested.

[0045] In this embodiment, the cylinder 110, the cover 120, the contact 10, and the locking nut 150 are coaxially arranged. The gas introduced can be nitrogen, air, or the like.

[0046] The working process of the contact airtightness testing device provided in this embodiment is as follows:

[0047] The first sealing ring 130 and the second sealing ring 140 are kept installed on the cover 120. In use, the contact 10 is inserted into the through hole 123 and the contact 10 and the cover 120 are connected by the lock nut 150. Then, the part of the contact 10 to be tested is inserted into the cylinder 110, and the cover 120 is connected to the cylinder 110 with screws. The air pipe connector is installed on the air inlet 111 to connect the air inlet pipe to the sealed space 101.

[0048] The encapsulation assembly containing the contact 10 is placed in water, and air is injected into the sealed space 101 through the air inlet pipe. If the airtightness of the contact 10 is qualified, no bubbles will appear in the water; if the airtightness of the contact 10 is not qualified, the gas will escape from the part of the contact 10 that passes through the perforation 123, and bubbles will appear in the water.

[0049] To improve testing efficiency, a single encapsulation component can be configured with multiple independent sealed spaces 101. Correspondingly, a cover 120 is provided with multiple first annular grooves 121 and second annular grooves 122, and the cylinder 110 is provided with a corresponding number of air inlets 111, thereby reducing the number of times the cover 120 and cylinder 110 are disassembled and reassembled. The multiple independent sealed spaces 101 can be arranged linearly, or in a rectangular or annular arrangement to avoid interference with the observation of test results caused by them being too close to each other.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
