Description

A photovoltaic connector terminal structure Technical Field

[0001] This application relates to the field of terminal technology, and in particular to a photovoltaic connector terminal structure. Background Technology

[0002] The published patent CN220692354U discloses a photovoltaic connector terminal structure that increases assembly reliability. It includes a negative plastic core with a forward-extending insertion post and a through-cavity. A female terminal is embedded in the cavity, and the female terminal has a retaining spring and a fixing ring. A second limiting groove, a frustum-shaped groove, is located in the middle of the cavity, with its bottom at the end furthest from the insertion post. A second step is located on the bottom of the second limiting groove. The female terminal has a cylindrical structure with a fixing ring at its front end and at the end closest to the insertion post. The retaining spring is located at the end of the fixing ring furthest from the insertion post. A retaining spring is located at the rear end of the fixing ring, with its thickness less than the thickness of the knob portion of the female terminal. This partial thinning of the retaining spring effectively reduces the defect rate and lowers costs.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0029] Referring to Figures 1-4, a photovoltaic connector terminal structure includes a male terminal 1, a female terminal 2, a first connecting shell 3, a second connecting shell 4, a first connecting mechanism 5, and a second connecting mechanism 7. Two grooves 6 are symmetrically formed on the male terminal 1 and the female terminal 2, and a second connecting mechanism 7 is provided inside each groove 6. The male terminal 1 and the female terminal 2 are respectively inserted into the first connecting shell 3 and the second connecting shell 4. The first connecting shell 3 and the second connecting shell 4 are fixed by the first connecting mechanism 5.

[0030] Referring to Figures 1-4, the connecting mechanism 5 includes a slot 51, a plug 52, and a slot 53. Both slots 51 are formed on the first connecting shell 3, and two plugs 52 that cooperate with the slots 51 are fixedly connected to the second connecting shell 4. When the plugs 52 on the second connecting shell 4 are inserted into the corresponding slots 51 on the first connecting shell 3, the first connecting shell 3 and the second connecting shell 4 can automatically lock when the protrusion on the plug 52 abuts against the slot 53, thereby improving the practicality of the device.

[0031] Referring to Figures 1-4, the first connecting shell 3 has two slots 53, and the two slots 53 are connected to the slot 51. The protruding parts of the two inserts 52 are connected to the slots 53. By manually pressing the two inserts 52 inward, the inserts 52 extend into the slot 51 and disconnect from the slots 53. Then, the second connecting shell 4 can be quickly disassembled from the first connecting shell 3, thereby improving the practicality of the device.

[0032] Referring to Figures 1-4, the second connecting mechanism 7 includes a mounting block 71, a spring plate 72, a telescopic spring 73, a V-groove 74, a screw 75, and a sleeve 76. Two mounting blocks 71 are fixedly connected inside each groove 6, and a spring plate 72 is provided inside each groove 6. Both ends of each spring plate 72 are slidably connected to the mounting block 71. By inserting the male terminal 1 into the first connecting shell 3, when the spring plate 72 in the groove 6 is engaged in the V-groove 74, the male terminal 1 is successfully connected to the first connecting shell 3, thereby improving the practicality of the device.

[0033] Referring to Figures 1-4, each mounting block 71 has a telescopic spring 73 on one side close to it, and the end of each telescopic spring 73 away from the mounting block 71 is fixedly connected to the spring plate 72. When the male terminal 1 is inserted into the first connecting shell 3 and the spring plate 72 coincides with the V-groove 74, under the action of the telescopic spring 73, the spring plate 72 in the groove 6 is inserted into the V-groove 74, and the male terminal 1 is successfully connected to the first connecting shell 3, thereby improving the practicality of the device.

[0034] Referring to Figures 1-4, two V-shaped grooves 74 are respectively opened inside the first connecting shell 3 and the second connecting shell 4, and each spring piece 72 is located inside the V-shaped groove 74. By opening the V-shaped grooves 74 inside the first connecting shell 3 and the second connecting shell 4, the V-shaped grooves 74 are used to lock the spring pieces 72 on the male terminal 1 and the female terminal 2, so that the male terminal 1 and the female terminal 2 can be successfully engaged with the first connecting shell 3 and the second connecting shell 4, thereby improving the practicality of the device.

[0035] Referring to Figures 1-4, the interiors of the first connecting shell 3 and the second connecting shell 4 are respectively threaded with two screws 75. One end of each screw 75 is fitted with a sleeve 76, and each sleeve 76 is threadedly connected to the first connecting shell 3 and the second connecting shell 4 respectively. Through the second connecting mechanism 7, disassembly can be performed quickly in a short time without the use of other auxiliary tools. The absence of a complex structural design makes operation simpler, improves work efficiency, and enhances the practicality of the device.

[0036] Working principle: During connection, firstly, insert the two cables into the male terminal 1 and the female terminal 2 respectively. Then, use a tool to press the rivet cup to fix the two cables to the male terminal 1 and the female terminal 2 respectively. Next, insert the male terminal 1 into the first connecting shell 3. When the spring piece 72 in the groove 6 is engaged in the V-shaped groove 74, the male terminal 1 is successfully connected to the first connecting shell 3. Then, insert the female terminal 2 into the second connecting shell 4. When the spring piece 72 in the groove 6 is engaged in the V-shaped groove 74, the female terminal 2 is successfully connected to the second connecting shell 4. Immediately afterwards, connect the first connecting shell 3 and the second connecting shell 4. Insert the plug 52 on the second connecting shell 4 into the corresponding slot 51 on the first connecting shell 3. When the protrusion on the plug 52 abuts against the slot 53, the first connecting shell 3 and the second connecting shell 4 automatically lock. The overall connection structure is simple, easy to understand, and can be quickly connected in a short time, improving installation efficiency.

[0037] When a cable malfunctions and needs to be disassembled, first rotate the sleeve 76 counterclockwise to disconnect it from the first connecting shell 3. Then rotate the screw 75 clockwise to extend the end of the screw 75 that contacts the spring plate 72 inward. Using the squeezing force on the spring plate 72, both ends of the spring plate 72 extend to the sides within the mounting block 71. At the same time, pull the male terminal 1 out of the first connecting shell 3. This allows for quick disassembly in a short time without the use of other auxiliary tools. The absence of a complex structural design makes operation simpler and improves work efficiency.
