[0001] The utility model relates to the field of connector, specifically to a connector's glue filling structure and female seat connector thereof. BACKGROUND
[0002] In the production process of Type-C female seat connector, the upper and lower two rows of terminal groups are first molded together with the upper and lower two insulating pieces by Molding process (in-mold injection molding process) respectively, forming two terminal modules, and then the upper and lower two insulating pieces are stacked and assembled, and after assembly, secondary Molding is performed around the upper and lower two rows of terminals to form an insulator between the upper and lower two rows of terminals to prevent mutual conduction between the terminals.
[0003] In the prior art, when performing secondary Molding around the upper and lower two rows of terminals, glue is usually filled on both sides of the two terminal modules in the mold, and the glue flows through the two sides of the two terminal modules and finally converges in the middle of the two terminal modules, and then undergoes a cooling injection molding process. This method causes more glue on the two sides of the terminal module and less glue in the middle due to the long flow path of the glue. This results in uneven distribution of the glue, and visual defects on the outside of the insulator formed by the cooled glue. To reduce this situation, the glue filling pressure is usually increased so that the glue can flow quickly through the two sides of the terminal module and finally converge in the middle of the terminal module.

[0028] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as there is no conflict.
[0029] The preferred embodiments of the present application will be further described with reference to the drawings, as shown in Figure 1 A glue filling structure of a connector, comprising an upper terminal module 100 and a lower terminal module 200 fixed together, a middle partition 300 is arranged between the upper terminal module 100 and the lower terminal module 200, the middle partition 300 comprises a base 310 arranged between the upper terminal module 100 and the lower terminal module 200, a bending arm 320 is arranged on one side of the base 310, a first glue guide groove 311 is arranged in the middle of the base 310, and glue inlets 312 are arranged on both sides of the base 310, the glue inlets 312 and the first glue guide groove 311 are in communication with each other, when the glue filling equipment fills glue in the inside of the upper terminal module 100 and the lower terminal module 200 from the glue inlets 312, the glue can flow along the middle of the base 310 through the first glue guide groove 311.
[0030] In the working process of the present embodiment, the upper terminal module 100, the lower terminal module 200 and the middle partition 300 are stacked together, and the middle partition 300 is located between the upper terminal module 100 and the lower terminal module 200, when the in-mold injection molding of the periphery of the upper terminal module 100 and the lower terminal module 200 is needed after assembly, the glue filling equipment can be used to fill glue in the inside of the upper terminal module 100 and the lower terminal module 200 from the glue inlets 312, because the glue inlets 312 and the first glue guide groove 311 of the base 310 are in communication with each other, so the glue will flow into the first glue guide groove 311 from the glue inlets 312, thereby flowing along the middle of the base 310 through the first glue guide groove 311 until flowing out from the middle of the upper terminal module 100 and the lower terminal module 200.
[0031] Compared with the prior art, the first glue guide groove 311 is arranged in the middle of the base 310, and the glue inlet 312 in communication with the first glue guide groove 311 is arranged on both sides of the base 310, so that when the glue filling equipment fills glue, the glue not only flows along the outside of the base 310, but also flows into the first glue guide groove 311 through the glue inlet 312, so that the glue can enter the inside of the upper terminal module 100 and the lower terminal module 200 and flow along the middle of the base 310 until flowing out from the middle of the upper terminal module 100 and the lower terminal module 200. In this way, when the glue is filled, the glue filling equipment does not need to exert too much glue inlet pressure, so that the glue can be more uniformly distributed around the upper terminal module 100 and the lower terminal module 200, the glue filling time is saved, and the product quality after glue filling is improved.
[0032] Further to the above embodiment, as shown in Figure 2 The upper terminal module 100 includes an upper terminal group 110 and a first insulating part 120, and the upper terminal group 110 and the first insulating part 120 are integrally formed by an injection molding process. The lower terminal module 200 includes a lower terminal group 210 and a second insulating part 220, and the lower terminal group 210 and the second insulating part 220 are integrally formed by an injection molding process. The first insulating part 120 includes a first main body part 121, and a first supporting part 122 extends from one side of the first main body part 121. The upper terminal group 110 is connected with the first supporting part 122 and protrudes outward from the top of the first supporting part 122. The second insulating part 220 includes a second main body part 221, and a second supporting part 222 extends from one side of the second main body part 221. The lower terminal group 210 is connected with the second supporting part 222 and protrudes outward from the bottom of the second supporting part 222. There is a gap between the first supporting part 122 and the second supporting part 222, so that the glue inlet 312 can be in communication with the first glue guide groove 311, and the glue can flow into the first glue guide groove 311 from the glue inlet 312 during glue filling.
[0033] In some embodiments, as shown in Figure 3 A positioning groove 222a recessed inward is arranged on the top of the second supporting part 222, and the middle partition plate 300 is arranged in the positioning groove 222a, so that the movement of the middle partition plate 300 between the upper terminal module 100 and the lower terminal module 200 can be better prevented when the middle partition plate 300 is assembled between the upper terminal module 100 and the lower terminal module 200.
[0034] Further to the above embodiment, as shown in Figure 3As shown, positioning rods 222b are arranged on both sides of the glue inlet 312, and the positioning rods 222b are fixed on the top of the second supporting part 222. When the nozzle of the glue filling device is inserted into the glue inlet 312 for glue filling, the positioning rods 222b can better prevent the nozzle from shaking left and right, thereby affecting the glue filling effect.
[0035] Further based on the above embodiments, as shown in Figure 3 As shown, a plurality of second glue guide grooves 222c are arranged in the middle of the side of the second supporting part 222 away from the second main body part 221, and the second glue guide grooves 222c are communicated with the first glue guide groove 311. When the glue filling device fills glue into the inside of the upper terminal module 100 and the lower terminal module 200 from the glue inlet 312, the glue can flow along the middle of the base 310 through the first glue guide groove 311. When the first glue guide groove 311 is filled with glue, the glue flows into the second glue guide groove 222c and then flows out of the middle of the upper terminal module 100 and the lower terminal module 200 through the second glue guide groove 222c, so that the glue is more evenly distributed around the upper terminal module 100 and the lower terminal module 200.
[0036] Further based on the above embodiments, as shown in Figure 3 As shown, a third glue guide groove 222d is formed by inwardly recessing the second supporting part 222, the third glue guide groove 222d is perpendicular to the second glue guide groove 222c and communicated with the first glue guide groove 311. When the first glue guide groove 311 is filled with glue, the glue flows into the third glue guide groove 222d, so that the glue can flow along the transverse direction of the second supporting part 222, thereby making the glue more evenly distributed around the upper terminal module 100 and the lower terminal module 200.
