[0002] Photovoltaic dedicated connection terminals are a type of terminal specifically used to connect photovoltaic modules or photovoltaic modules to inverters. Photovoltaic dedicated connection terminals are usually made of materials with strong high temperature and weather resistance to ensure normal use in various harsh environments.

[0003] Because the female terminals inside the female connectors of some photovoltaic-specific connection terminals are prone to misalignment and displacement after multiple repairs, once the female terminals are docked in a misaligned state, not only can they not be properly docked and installed, but they may even directly damage the terminals. However, the existing devices do not have relevant measures to adjust this phenomenon, and the overall practical effect is poor. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned problem and to propose a photovoltaic-specific connection terminal, which improves the existing photovoltaic-specific connection terminal, in which the female terminal inside the female connector is easily misaligned after multiple repairs. Once the female terminal is docked in a misaligned state, it cannot be docked and installed normally, and may even directly damage the terminal.

[0005] A photovoltaic-specific connection terminal comprises a female connector body, a female terminal body, a male connector body and a male terminal body: a female terminal body is arranged inside the female connector body, a male terminal body is arranged inside the male connector body, a protective support mechanism is connected between the female connector body and the male connector body, an auxiliary positioning mechanism is arranged on the side of the protective support mechanism, a resistance support mechanism is arranged outside the female terminal body, the protective support mechanism comprises a resistance clamping ring, a limiting ring and a resistance slot, a resistance clamping ring is arranged on the side outer wall of the male connector body, a limiting ring is arranged on the side outer wall of the female connector body, a resistance slot is opened on the side outer wall of the limiting ring, and the resistance clamping ring and the resistance slot are snap-fitted and installed.

[0006] Preferably, the auxiliary positioning mechanism includes a mounting ring and a limiting T-slot, the side outer wall of the female connector body is provided with a mounting ring, the side outer wall of the mounting ring is fitted with the side inner wall of the limiting ring, and the side inner wall of the mounting ring is provided with limiting T-slots at equal intervals.

[0007] Preferably, the side outer wall of the male connector body is surrounded by limit T-shaped strips at equal intervals, and the limit T-shaped strips and the limit T-shaped grooves are slidably mounted.

[0008] Preferably, the abutting support mechanism includes a protective sleeve and a support ring. The female terminal body is arranged inside the protective sleeve. The protective sleeve is connected to the outer side wall of the female connector body. A support ring is arranged on the inner side wall of the protective sleeve.

[0009] Preferably, the support ring is arranged in a cavity structure, and support members are slidably mounted around the inside of the support ring at equal intervals. Abutting springs are connected between the outer side wall of the support member and the inner side wall of the support ring.

[0010] Preferably, a support shaft is arranged on the outer side wall of the support member. The extending end of the support shaft is arranged outside the support ring and is connected to the outer side wall of the abutting ring. Arc-shaped structures are arranged on both outer side walls of the abutting ring.

[0011] The beneficial effects of the present utility model are:

[0012] 1. When the photovoltaic special connection terminal is in use, through the settings of the protective sleeve, support ring, support member, abutting spring, support shaft and abutting ring, using the characteristic that the spring will generate a reaction force synchronously under the abutting force, when the female terminal is installed into the female connector, the abutting spring can make the abutting ring tightly abut against the outside of the female terminal through the reaction force. At the same time, a plurality of abutting rings are arranged in an equal-spacing and circumferential manner. In this way of annular abutting support, the female terminal can be abutted at the central position inside the female connector, thereby further ensuring the docking stability of the subsequent terminals on the basis of ensuring the central position placement of the female terminal, and the overall practical effect is good;

When the photovoltaic special connection terminal is in use, by pre-positioning the installation of the terminal through the settings of the limiting T-shaped strip and the limiting T-shaped groove, the terminal can be directly and accurately docked after positioning. Compared with the existing method of adjusting and docking, it has a good protective effect on the terminal. At the same time, in combination with the use of the abutting snap ring and the limiting ring to form a sealing protective layer, it has a sealing and protective effect on the connection part of the female connector and the male connector, thereby enhancing the waterproof and dustproof performance of the connection terminal, and the overall protective effect is good.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] When implementing: Figures 1-5 As shown, a photovoltaic-specific connection terminal comprises a female connector body 1, a female terminal body 2, a male connector body 3 and a male terminal body 4: the female connector body 1 is provided with a female terminal body 2, the male connector body 3 is provided with a male terminal body 4, a protective support mechanism 5 is connected between the female connector body 1 and the male connector body 3, an auxiliary positioning mechanism 6 is provided on the side of the protective support mechanism 5, a resisting support mechanism 7 is provided on the outside of the female terminal body 2, the protective support mechanism 5 comprises a resisting clamping ring 51, a limiting ring 52 and a resisting clamping groove 53, a side outer wall of the male connector body 3 is provided with a resisting clamping ring 51, and a side outer wall of the female connector body 1 is provided with a limiting ring 52, a side outer wall of the limiting ring 52 is provided with a contact groove 53, and the contact clamping ring 51 and the contact groove 53 are snap-fitted together; when the device is in use, the female terminal body 2 and the male terminal body 4 need to be crimped with the corresponding wiring harnesses respectively according to the existing crimping method, and then they are inserted into the female connector body 1 and the male connector body 3 respectively. When the female connector body 1 and the male connector body 3 need to be docked, it is only necessary to snap the contact clamping ring 51 into the inside of the contact groove 53, and then the limiting ring 52 and the contact clamping ring 51 are assembled and installed to form a complete closed space, thereby achieving a closed and protective effect on the connection between the female connector body 1 and the male connector body 3.

[0022] The auxiliary positioning mechanism 6 includes a mounting ring 61 and a limiting T-slot 62. The side outer wall of the female connector body 1 is provided with a mounting ring 61. The side outer wall of the mounting ring 61 fits with the side inner wall of the limiting ring 52. The side inner wall of the mounting ring 61 is provided with limiting T-slots 62 at equal intervals. The side outer wall of the male connector body 3 is provided with limiting T-slots 63 at equal intervals. The limiting T-slot 63 and the limiting T-slot 62 are slidably installed. When it is necessary to dock the female connector body 1 and the male connector body 3, it is only necessary to push the limiting T-slot 63 to the corresponding position of the limiting T-slot 62 to complete the positioning and docking of the female connector body 1 and the male connector body 3. After the female connector body 1 and the male connector body 3 are limited, the male connector body 3 will be directly aligned to enter the interior of the female terminal body 2, thereby achieving the effect of precise docking.

[0023] The resistance support mechanism 7 includes a protective sleeve 71 and a support ring 72. The female terminal body 2 is arranged inside the protective sleeve 71. The protective sleeve 71 is connected to the side outer wall of the female connector body 1. The side inner wall of the protective sleeve 71 is provided with a support ring 72. The support ring 72 is set as a cavity structure, and the support ring 72 has support members 73 installed in a circumferential sliding manner at equal intervals inside. A resistance spring 74 is connected between the side outer wall of the support member 73 and the side inner wall of the support ring 72. A support shaft 75 is provided on the side outer wall of the support member 73. The protruding end of the support shaft 75 is arranged outside the support ring 72, and the protruding end of the support shaft 75 is connected to the side outer wall of the resistance ring 76. The two ends of the resistance ring 76 The side outer walls are all provided with an arc structure; when the female terminal body 2 passes into the interior of the female connector body 1, the female terminal body 2 contacts the contact ring 76, causing the contact ring 76 to displace and drive the support shaft 75 to move, thereby driving the support member 73 to slide inside the support ring 72. At this time, the contact spring 74 is squeezed by the support member 73 and is in a contracted state. At the same time, the contact spring 74 is squeezed and generates a reaction force to push the support member 73 to move in the opposite direction. Subsequently, the movement of the support member 73 will automatically push the support shaft 75 to move and then push the contact ring 76 to move. When the contact ring 76 moves, it will automatically fit on the outer wall of the female terminal body 2, thereby achieving the effect of centering the female terminal body 2.

[0024] When the utility model is in use, the device needs to crimp the female terminal body 2 and the male terminal body 4 with the corresponding wiring harness according to the existing crimping method, and then insert them into the female connector body 1 and the male connector body 3 respectively. When the female connector body 1 and the male connector body 3 need to be docked, it is only necessary to push the limiting T-shaped strip 63 to the limiting T-shaped groove 62 at the corresponding position to complete the positioning and docking of the female connector body 1 and the male connector body 3. Then, after the female connector body 1 and the male connector body 3 are limited, the male connector body 3 will be directly aligned to enter the interior of the female terminal body 2, so as to achieve the effect of precise docking. When the female connector body 1 and the male connector body 3 are docked, the contact clamping ring 51 is automatically engaged with the inside of the contact clamping groove 53, and then the limiting ring 52 and the contact clamping ring 51 are combined and installed to form a complete closed space, thereby playing a closed and protective effect on the connection between the female connector body 1 and the male connector body 3;

[0025] When the female terminal body 2 passes into the interior of the female connector body 1, the female terminal body 2 contacts the contact ring 76, causing the contact ring 76 to be displaced, driving the support shaft 75 to move and then driving the support member 73 to slide inside the support ring 72. At this time, the contact spring 74 is squeezed by the support member 73 and is in a contracted state. At the same time, the contact spring 74 is squeezed and generates a reaction force to push the support member 73 to move in the opposite direction. Subsequently, the movement of the support member 73 will automatically push the support shaft 75 to move and then push the contact ring 76 to move. When the contact ring 76 moves, it will automatically fit on the outer wall of the female terminal body 2, thereby achieving the effect of centering the female terminal body 2.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
