Anti-loosening photovoltaic connector and cable assembly thereof

Abstract

The utility model discloses an anti-loosening photovoltaic connector. The anti-loosening photovoltaic connector comprises a housing, a first connecting terminal and a second connecting terminal. The interior of the shell is hollowed out to form a mounting chamber, and blocking pieces are symmetrically arranged in the shell. One end of the first connection terminal is inserted into one end of the second connection terminal, and the other end of the first connection terminal and the other end of the second connection terminal make contact with different blocking pieces respectively. According to the anti-loosening photovoltaic connector and the cable assembly thereof, the first connecting terminal and the second connecting terminal are limited by adopting the symmetrically arranged blocking pieces, so that poor contact caused by loosening of a cable joint part in use is avoided. And the connection operation is fast, and the first connection terminal and the second connection terminal only need to be oppositely inserted and then are pressed between the symmetrically arranged blocking pieces, so that the fast connection of the cable is facilitated.

Description

Technical Field

[0001] The utility model relates to connector technology, in particular to an anti-loosening photovoltaic connector and a cable assembly thereof. Background Art

[0002] Photovoltaics are connected by cables, but the middle of the cables needs to be connected to achieve longer distance transmission. After the positive and negative metal parts of the existing photovoltaic connector are connected, the positive metal part is squeezed by the strand spring inside the positive metal part to maintain reliable contact. However, after long-term use, the elasticity of the strand spring is often reduced, and the squeezed negative metal part becomes loose, resulting in excessive resistance at the contact point. After power is turned on, it continues to heat up and eventually burns the connector, or even causes a fire. Utility Model Content

[0027] The blocking member 5 is composed of a blocking plate 6 and a limiting plate 7 vertically arranged with the blocking plate 6. The limiting plates 7 are symmetrically arranged, and a mounting opening 8 is formed in the middle of the limiting plates 7. The mounting opening 8 is used to limit the first connection terminal 2 and the second connection terminal 3 so that they can be limited in the middle of the symmetrically arranged blocking member 5. A through hole 9 is provided in the middle of the blocking plate 6, and the through hole 9 is used for the cable 10 to pass through, so as to keep the cable 10 fixed to the first connection terminal 2 and the second connection terminal 3.

[0028] The first connection terminal 2 is composed of a first column 11 and a first contact body 12, and a plurality of strip grooves 13 are provided on the first column 11. A fixing portion 14 and a blocking arm 15 are provided on the first contact body 12, and an open groove 16 is provided between the fixing portion 14 and the blocking arm 15. The second connection terminal 3 is composed of a second column 17 and a second contact body 18, and a plurality of retaining arms 19 cooperating with the strip grooves 13 are provided on the second column 17, and a fixing portion 14 and a blocking arm 15 are provided on the second contact body 18, and an open groove 16 is provided between the fixing portion 14 and the blocking arm 15.
