[0024] Refer to Figure 1 、 2As shown in Figures 3, 4, 5, 6, and 7, which are schematic diagrams of the preferred embodiments of the present invention, the present invention relates to a split connector, which has a first insulator 1, a first terminal 2 assembled on the first insulator 1, a second insulator 3, and a second terminal 4 assembled on the second insulator 3. The first insulator 1 is provided with a first rubber core part 11 and a first splicing part 12 protruding from the first rubber core part 11 in a first direction. The first terminal 2 is positioned in the first rubber core part 11 for external electrical connection. The second insulator 3 is provided with a second rubber core part 31 and a second splicing part 32 protruding from the second rubber core part 31 in the first direction. The second terminal 4 is positioned on the second rubber core part 31 for external electrical connection. The first insulator 1 and the second insulator 3 are connected together by splicing the first splicing part 12 and the second splicing part 32 in the first direction, and the first rubber core part 11 and the second rubber core part 31 are spaced apart in the first direction to form a slot 5. The first direction is the direction in which the first insulator 1 and the second insulator 3 are spliced and stacked. The first terminal 2 has a first contact part 21 facing the slot 5 and exposed, and the second terminal 4 has a second contact part 41 facing the slot 5 and exposed. In this way, a slot connector is constructed. The spatial size of the slot 5 and the number of the first terminal 2 and the second terminal 4 can be set according to actual needs to meet the plug-in connection of different external daughter boards 6. The first contact part 21 and the second contact part 41 form a clamping contact insertion of the external daughter board 6 facing each other to form a circuit connection and meet the electrical signal transmission.

[0025] Figure 1 , 2 As shown in Figures 3, 4, 5, 6, and 7, in this embodiment, both the first insulator 1 and the second insulator 3 are in the shape of a Chinese character 'Gong', and both the first rubber core part 11 and the second rubber core part 31 extend in a direction perpendicular to the first direction. A ring groove-shaped first terminal groove 111 is provided on the outer peripheral surface of the first rubber core part 11. The first terminal 2 is in a U shape and is embedded in the first terminal groove 111 based on a clamping connection, which is convenient for manufacturing and assembly. A protruding first hot melt column 112 is provided in the first terminal groove 111. After passing through a preset fixing hole on the first terminal 2, the first hot melt column 112 adhesively connects the first terminal 2 by hot melting, increasing the installation stability and usability of the first terminal 2. A ring groove-shaped second terminal groove 311 is also provided on the outer peripheral surface of the second rubber core part 31. The second terminal 4 is in a U shape and is embedded in the second terminal groove 311 based on a clamping connection. A protruding second hot melt column 312 is provided in the second terminal groove 311. After passing through a preset fixing hole on the second terminal 4, the second hot melt column 312 adhesively connects the second terminal 4 by hot melting. The structure is simple, convenient for manufacturing and assembly, and also increases the installation stability and usability of the second terminal 4.

[0026] The first splicing part 12 is distributed at both ends of the first rubber core part 11 and is a connecting wall that is symmetric left and right. The first splicing part 12 is provided with a guiding post 121, a first connecting arm 122, and a first connecting hole 123. The second splicing part 32 is distributed at both ends of the second rubber core part 31 and is also a connecting wall that is symmetric left and right. The second splicing part 32 is provided with a guiding groove 321, a second connecting arm 322, and a second connecting hole 323. When the first splicing part 12 and the second splicing part 32 are spliced in the first direction, the guiding post 121 is inserted into the guiding groove 321, which plays a role of positioning and guiding, and can guide the assembly of the first insulator 1 and the second insulator 3. The first connecting arm 122 is inserted into the second connecting hole 323 to form an anti-withdrawal connection, and the second connecting arm 322 is inserted into the first connecting hole 123 to form an anti-withdrawal connection. This prevents the first insulator 1 and the second insulator 3 from loosening, makes the connection between the first insulator 1 and the second insulator 3 stable, ensures that the slot 5 can be adapted to the external daughter board 6 for insertion, and ensures that the first contact part 21 and the second contact part 41 can maintain good contact connection with the inserted external daughter board 6.

[0027] In this embodiment, the guiding post 121, the first connecting arm 122, and the first connecting hole 123 are all designed in pairs on the first insulator 1 and are symmetrically distributed in the first direction. The guiding post 121 protrudes from the splicing surface of the first splicing part 12, and the first connecting arm 122 is led out from the outer side surface of the first splicing part 12 and protrudes in the same direction as the guiding post 121, and the protruding end of the first connecting arm 122 is provided with a first barb 1221. The first connecting hole 123 is an earring structure provided on the outer side surface of the first splicing part 12. Similarly, the guiding groove 321, the second connecting arm 322, and the second connecting hole 323 are all designed in pairs on the second insulator 3 and are symmetrically distributed in the first direction. The guiding groove 321 is a groove that is recessed from the splicing surface of the second splicing part 32, and the second connecting arm 322 is led out from the outer side surface of the second splicing part 32 and protrudes toward the first insulator 1, and the protruding end of the second connecting arm 322 is provided with a second barb 3221. The second connecting hole 323 is an earring structure provided on the outer side surface of the second splicing part 32. After the first connecting arm 122 is inserted into the second connecting hole 323, the first barb 1221 hooks the corresponding hanging platform on the second connecting hole 323 to establish an anti-withdrawal connection. After the second connecting arm 322 is inserted into the first connecting hole 123, the second barb 3221 hooks the corresponding hanging platform on the first connecting hole 123 to establish an anti-withdrawal connection. The buckle assembly is beneficial to product manufacturing and also improves the assembly convenience. The assembly can be completed only by pushing the first insulator 1 and the second insulator 3 together relatively. When disassembling, the first barb 1221 and the second barb 3221 are withdrawn from the hanging connection, and the first insulator 1 and the second insulator 3 can be separated relatively.

[0028] Further, the first connecting arm 122 and the second connecting arm 322 of this embodiment are arranged in a vertically staggered manner in the first direction, which is conducive to manufacturing and assembly, enabling continuous splicing of multiple first insulators 1 and second insulators 3 to construct a connector in the form of multiple slots, such as Figure 7 As shown, this structural design further balances the splicing force and enables stable connection between the first insulator 1 and the second insulator 3.

[0029] The split connector provided by the present utility model can be self-assembled and infinitely expanded to meet actual needs; by using different insulators for splicing and connection, with modular design and manufacturing, the structure is simple, facilitating manufacturing, disassembly and assembly, and the connection structure is stable and practical, which is conducive to the miniaturization and multi-function development of connector products.

[0030] Although the preferred specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, the present utility model should not be limited to the exact same structure and operation as described above and shown in the drawings. For those skilled in the art of this technology, many equivalent improvements and variations can be made to the above embodiments through logical analysis, reasoning or limited experiments without departing from the concept and scope of the present utility model, and these improvements and variations should all fall within the scope of protection required by the present utility model.
