[0046] In the photovoltaic connector of this embodiment, a spring-type crimping unit including a pressure piece and an elastic sheet is provided in at least one of the plugs in the male plug and the female plug, so that when it is necessary to remove or install the cable, an operating force can be applied to the pressure piece, and the pressure piece presses the elastic sheet to form a gap for the cable to pass through. In this way, the cable can be passed through the gap to complete the electrical connection between the cable and the electrical connector in the corresponding plug, or the cable can be passed through the gap and moved out to the outside of the plug, thereby facilitating and quickly completing the cable removal or installation of the photovoltaic connector.

[0047] As a way to realize the pressure member pressing the elastic sheet, the pressure member 3 of this embodiment is a wrench, and a pivot (not shown in the figure) that cooperates with the wrench to rotate back and forth is provided in the spring-type crimping unit.

[0048] After the pressure piece adopts a wrench, in order to cooperate with the pressure piece to press the elastic piece, so as to facilitate the cable to pass through the corresponding plug connection port into the plug, in this embodiment, see Figure 8 As shown, the pressure member 3 is formed with a through hole 30 for the cable L to pass through. The through hole 30 is configured to correspond to the wiring port of the plug in which the pressure member 3 is located. Thus, as the wrench is turned, it rotates. When the through hole 30 on the pressure member 3 aligns with the wiring port of the plug, the cable can be passed through the wiring port and the through hole 30, thereby completing the cable removal or installation.

[0049] In order to prevent the first electrical connector 11 from being separated from the male plug due to external pulling force, the male plug 1 of this embodiment has a first anti-separation structure to prevent the first electrical connector 11 from being separated from the plug.

[0050] In order to prevent the second electrical connector 21 from being detached from the female plug due to external pulling force, the female plug 2 of this embodiment has a second anti-detachment structure to prevent the second electrical connector 21 from being detached from the plug.

[0051] In order to prevent the elastic sheet from being detached due to excessive rebound force, in this embodiment, a bending portion is formed on the electrical connector in the plug where the spring-type crimping unit is located. The bending portion is configured to limit the maximum rebound stroke of the elastic sheet 4 in the spring-type crimping unit.

Figure 16 As shown, the tail of the second electrical connector 21 is provided with a second opening groove 211 and a second limiting baffle 212. The cable passes through the second opening groove 211 of the second electrical connector 21 in the female plug 2 and is blocked by the second limiting baffle 212, thereby achieving the effect of stopping the cable in the female plug.

[0053] In order to effectively fix and install the elastic sheet in the plug having the above-mentioned spring-type crimping unit, in this embodiment, the electrical connector in the plug where the spring-type crimping unit is located has an installation and matching structure for matching and installing the elastic sheet in the spring-type crimping unit. For example, see Figure 10 As shown in the male plug 1, the first electrical connector 11 is provided with a first engaging surface 11b engaging with the upper end surface 41 of the elastic piece 4 and a second engaging surface 11c engaging with the lower end surface 42 of the elastic piece 4.

For example, the first plug body 12 is provided with a hanging platform 121, and the second plug body 22 is provided with a buckle 221 that snap-fits with the hanging platform 121. In this way, the first plug body 12 and the second plug body 22 are assembled together through the snap-fit ​​between the hanging platform 121 and the buckle 221.

[0055] In the photovoltaic connector of this embodiment, the male plug 1 has a clamping ring 5, a rear end body 6, a locking wire nut 7, a sealing plug 8 and a sealing ring 9. The clamping ring 5 is sleeved on the outside of the first electrical connector 11 in the male plug and fixed on the inside of the first plug body 12 of the male plug. The rear end body 6 is located at the rear end of the first plug body 12 and assembled with the first plug body 12; wherein, the pressure member 3 is arranged on the rear end body 6, the pivot is also located on the rear end body 6, and the elastic sheet 4 is located on the inside of the rear end body 6; the locking wire nut 7 is located at the rear end of the first plug body 12 and assembled with the first plug body 12 through a threaded structure. The locking wire nut 7 is formed with a wiring port 70 for the cable L to pass through, and the rear end body 6 is located on the inside of the locking wire nut 6; the sealing plug 8 is arranged on the inside of the locking wire nut 7 and is engaged with the rear end body 6; the sealing ring 9 is sleeved on the outside of the rear end body 6 and is located between the rear end body 6 and the first plug body 12; wherein, the first electrical connector 11 is located in the first plug body 12 of the male plug.

[0056] As a way to fix the collar inside the first plug body, in this embodiment, see Figure 10 and Figure 7 As shown, the collar 5 is formed with a plurality of undercuts 51, and the inner side of the first plug body 12 is formed with a first inner groove 120 that fits the undercuts 51.

In this way, when the pressure piece 3 of the wrench is pushed upward, the first force-bearing surface 31 of the pressure piece 3 contacts the first groove 401 of the elastic piece 4 to form a first force point, and then the second force-bearing surface 32 of the pressure piece 3 contacts the trajectory plane 6a of the rear end main body 6 to form a second force point; when the pressure piece 3 is continued to be pushed upward to cause displacement, the first force-bearing surface 31 of the pressure piece 3 contacts the first groove 401 of the elastic piece 4 to form a force and press the elastic piece 4 downward. When the pressure piece 3 is pushed upward to the specified position, the pressure piece 3 contacts the stop surface 61 in the first plug body 12, so that the pressure piece 3 cannot continue to move. At this time, the pressure member 3 is in a stationary state, and the elastic sheet 4 is also in a stressed state of being pressed downward. The through hole 30 of the pressure member 3, the wiring through hole 62 formed on the rear end main body 6, and the elastic sheet 4 in the pressed downward state together form a threading space for the cable L to pass through.
