Embodiment

[0040] Please refer to figure 1 , this embodiment provides a junction box, including: a box cover 100 and a buffer chamber 200 .

[0041] Wherein, a shrinkable buffer chamber 200 is provided on one side of the box cover 100, and the inner cavity of the buffer chamber 200 communicates with the inner cavity of the box cover 100; it can be used for accommodating sealant.

[0042] It should be noted that the box cover 100 includes a first box flap 110 and a second box flap 120 that are fastened to each other (the fastening means that the first box flap 110 and the second box flap 120 are detachably connected, and in order to prevent water, the first box flap 110 and the second box flap 120 must ensure a certain degree of airtightness after being fastened), the first box flap 110 and the second box flap 120 have an accommodating cavity 130 for accommodating line connectors, (Currently, spot welding of the circuit board is used, and the joints at both ends are welded on the circuit...

Abstract

A junction box relates to the field of line communication, and comprises a box cover, one side of the box cover is provided with a retractable buffer chamber, and the inner cavity of the buffer chamber is communicated with the inner cavity of the box cover; and sealant can be accommodated. Through the arrangement of the retractable buffer chamber, when the sealant is injected into the accommodating cavity, the sealant can enter the buffer chamber through the expansion of the buffer chamber, and after the sealant is injected and the sealant is gradually shrunk in the cooling process, the sealant can be gradually shrunk through the buffer chamber; the sealant in the buffer chamber is extruded into the containing cavity, so that the difference value of volume reduction after the sealant in the containing cavity is cooled is made up, it is guaranteed that the containing cavity is always filled with the sealant after the sealant is cooled, and the problem that air enters the containing cavity to generate bubbles due to the fact that the volume of the sealant is reduced after the sealant is cooled is fundamentally solved.

Description

technical field [0001] The invention relates to the field of line communication, in particular to a junction box. Background technique [0002] At present, although the existing junction boxes can wrap the joints of the lines to avoid direct exposure of the joints to the air, causing short circuits or even electric shocks, their sealing performance is poor, and water is easy to enter the gaps of the junction boxes, resulting in There is a short circuit at the connector of the line. [0003] In view of this, this application is proposed. Contents of the invention [0004] The purpose of the present invention is to provide a junction box, which can ensure good sealing performance and avoid problems such as short circuit at the line joint caused by water ingress in the junction box during long-term practical use. [0005] Embodiments of the present invention are achieved like this: [0006] A junction box, comprising: a box cover, a shrinkable buffer chamber is arranged on...
