Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Unless defined otherwise, all technical terms used in the examples of the present application have the same meaning as commonly understood by one of ordinary skill in the art.

In order to make the technical solution and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, the embodiment of the present application provides a connector, which includes a transfer PCB 100 (Printed Circuit Board ), a plurality of first terminals 200, a plurality of second terminals 300, a plurality of third terminals 400, and a housing 500. The adapting PCB board 100 is fixed to the base 500. The transfer PCB 100 has two surfaces in a thickness direction, and a plurality of first terminals 200 and a plurality of second terminals 300 are respectively mounted on the two surfaces of the plugging end of the transfer PCB 100. The third terminals 400 are mounted at the fixed end of the adapting PCB 100 and extend through the base 500. The corresponding first and second terminals 200 and 300 are electrically connected to the corresponding third terminals 400 through the relay PCB board 100. It should be noted that, the portion of the third terminal 400 protruding from the housing 500 is used for soldering together the PCB board that is docked with the connector, so that current or signal transmission can be achieved. The corresponding first and second terminals 200 and 300 being electrically connected to the corresponding third terminals 400 through the transfer PCB board 100 means that each corresponding terminal is electrically connected through a printed circuit on the transfer PCB board 100.

In the connector provided in this embodiment of the present application, the fixed end of the adapting PCB board 100 is fixed on the base 500, the plurality of first terminals 200 and the plurality of second terminals 300 are respectively mounted on two surfaces of the plugging end of the adapting PCB board 100, and the plurality of third terminals 400 are fixed on the fixed end of the adapting PCB board 100 and extend through the base 500. Since the corresponding first and second terminals 200 and 300 are electrically connected to the corresponding third terminals 400 through the transit PCB 100, the current or signal input to the first and second terminals 200 and 300 can be transited by the transit PCB 100 and then output through the third terminals 400. That is, the corresponding first terminals 200 and second terminals 300 may share the third terminals 400, so that the number of the third terminals 400 is less than the sum of the numbers of the first terminals 200 and second terminals 300, and thus, when the connector is soldered and fixed to the PCB board to which the connector is mated, the number of terminals to be soldered on the mated PCB board is less, so that the difficulty of mounting the chip is reduced, and the soldering area of the PCB board to which the connector is mated is saved.

Details and functions of the connector provided in the embodiments of the present application are described in more detail below with reference to fig. 1 to 6.

As shown in fig. 2, in some embodiments, the fixing end of the adapting PCB board 100 is provided with a plurality of fixing through holes 110. One end of the third terminal 400, which is close to the first terminal 200, passes through the corresponding fixing through hole 110 and is fixed on the adapting PCB 100. So that the third terminal 400 can be positioned. In some embodiments, an end of the third terminal 400 near the first terminal 200 has a bending portion 410, where the bending portion 410 of the third terminal 400 is snapped into the corresponding fixing through hole 110, so that the position of the third terminal 400 can be initially positioned, so as to fix the third terminal 400 on the adapting PCB board 100 later.

In some embodiments, an end of the third terminal 400 near the first terminal 200 is fixed on the interposer PCB board 100 by SMT technology (Surface Mounted Technology, surface mount technology). The SMT technology refers to a circuit mounting technology for mounting components on a surface of a PCB board or other substrate, and soldering and assembling the components by reflow soldering or dip soldering. It should be noted that, the first terminal 200 and the second terminal 300 are also fixed on the adapting PCB board 100 by SMT technology.

In some embodiments, the housing 500 is injection molded integrally with the adapter PCB board 100. It should be noted that, the base 500 and the adapting PCB 100 may be integrally injection molded by an IM (Insert Molding) technique. The IM technology refers to a technology of placing a printed sheet into an injection mold, injecting an injection molding material on the surface of the sheet, and integrating the injection molding material and the sheet into an integral curing molding, wherein the plastic material may be plastic. It can be understood that when injection molding is performed, the transfer PCB 100 with the plurality of first terminals 200, the plurality of second terminals 300 and the plurality of third terminals 400 fixed thereon is placed in an injection mold, then an injection molding material is injected into the surface of the transfer PCB 100, the shape formed by the plastic in the mold is the shape of the base 500, and after injection molding, a structure in which the injection molding material and the transfer PCB 100 are integrated can be obtained.

As shown in fig. 2, in some embodiments, a plurality of injection molding through holes 120 are provided on the adapting PCB board 100, and the injection molding through holes 120 are filled with an injection molding material. When the injection molding is performed, the injection molding material starts to be in a flowing state, and through the injection molding through holes 120 formed in the transfer PCB 100, the injection molding material can uniformly cover the surface of the transfer PCB 100, so that the bonding strength of the injection molding material and the transfer PCB 100 is improved. It will be appreciated that since the first and second terminals 200 and 300 are used to transmit current or signals, the injection molding material does not cover the first and second terminals 200 and 300. The number of the injection molding through holes 120 can be set according to needs, as shown in fig. 2, three injection molding through holes 120 are arranged on the adapting PCB board 100, namely, a first injection molding through hole 121, a second injection molding through hole 122 and a third injection molding through hole 123, wherein the first injection molding through hole 121 and the third injection molding through hole 123 are respectively located at two sides of the adapting PCB board 100, and the second injection molding through hole 122 is located between the first injection molding through hole 120 and the third injection molding through hole 123. This way of disposing the injection molding through hole 120 can provide a more omnibearing flow channel for the injection molding material, so that the injection molding material can be uniformly injection molded on the surface of the adapting PCB board 100. It should be noted that, each injection molding through hole 120 has a certain distance from the first terminal 200 and the second terminal 300, so that the injection molding material is prevented from directly covering the first terminal 200 or the second terminal 300 during injection molding. It should be noted that, the shape of the injection molding through hole 120 may be set according to the need, for example, a circle, a rectangle, a triangle, etc., and the shape of the injection molding through hole 120 set on the adapting PCB board 100 shown in fig. 2 is a waist-shaped hole. In some embodiments, the extending direction of the first injection molding through hole 120 and the extending direction of the third injection molding through hole 123 are the same as the extending direction of the first terminal 200, and the extending direction of the second injection molding through hole 122 is perpendicular to the extending direction of the first injection molding through hole 120, so that the injection molding material can be ensured to circulate from all directions to the surface of the adapting PCB board 100 and be injection molded with the adapting PCB board 100 as a whole.

As shown in fig. 3, in some embodiments, the connector further includes a protective frame 600, the protective frame 600 being mounted on an outer edge of the mating end of the transfer PCB 100. Through setting up the protection frame 600, when the connector carries out plug with other devices, avoided the grafting end of switching PCB board 100 to produce wearing and tearing or bump bad phenomenon to can protect switching PCB board 100 better, prolonged switching PCB board 100's life, also prolonged the life of connector promptly.

As shown in fig. 2, in some embodiments, the protection frame 600 is U-shaped, and a clamping groove 610 is provided on a side of the protection frame 600 near the adapting PCB 100, where the clamping groove 610 is used to clamp into an edge of the adapting PCB 100. By providing the card slot 610, not only is assembly facilitated, but also better spacing of the adapter PCB board 100 is facilitated. The transfer PCB 100 is injection molded after being fixed with the first terminal 200, the second terminal 300, the third terminal 400 and the protection frame 600, so that various structures on the transfer PCB 100 can be better combined into a whole, and the combination strength is higher.

It can be appreciated that, in the injection molding process, the protection frame 600 is integrated with the base 500, wherein a portion of the protection frame 600 close to the fixed end of the adapting PCB board 100 is wrapped by the injection molding material, so that the protection frame 600 can be better fixed, and the phenomenon that the protection frame 600 falls off from the adapting PCB board 100 after the connector is plugged for many times is avoided. Meanwhile, the outer surface of the part of the protection frame 600 away from the fixed end of the adapting PCB 100 is exposed and is not covered by the injection molding material, so that the protection frame 600 can protect the plugging end of the adapting PCB when the connector is plugged with other devices.

In some embodiments, the material of the protection frame 600 is a metal material or a ceramic material with hardness greater than that of plastic. Because the strength and hardness of the protection frame 600 are greater, the protection frame is not easy to deform, and is not easy to be worn or damaged by other devices, the plugging end of the adapting PCB 100 can be better protected, so that the service life of the adapting PCB 100 is prolonged, namely, the service life of the connector is prolonged.

As shown in fig. 4, in some embodiments, the connector further includes an inner housing 700, the inner housing 700 is connected to the base 500, and the plugging end of the adapting PCB board 100 is located in the inner housing 700 and is exposed from the opening of the inner housing 700 away from the base 500. Referring to fig. 1 and 4, in some embodiments, the housing 500 includes a positioning portion 510, a first fixing portion 520, and a second fixing portion 530, and the positioning portion 510 is located between the first fixing portion 520 and the second fixing portion 530 in the plugging direction of the connector. The first fixing portion 520 is injection molded with the plugging end of the adapting PCB 100, and the second fixing portion 530 is injection molded with the fixing end of the adapting PCB 100. It is understood that the plurality of third terminals 400 extend through the second fixing portion 530, and the socket 500 can better position the plurality of first terminals 200, the plurality of second terminals 300, and the plurality of third terminals 400 mounted on the interposer PCB board 100. The inner housing 700 is sleeved on the outer surface of the positioning portion 510, and the inner housing 700 abuts against the second fixing portion 530 in the plugging direction of the connector. As shown in conjunction with fig. 4 and 5, in some embodiments, the inner housing 700 is provided with an inner housing through hole 710, wherein the mating end of the adapter PCB board 100 penetrates into the inner housing through hole 710 and emerges from the inner housing through hole 710. It should be noted that, the thickness of the positioning portion 510 is greater than the thickness of the first fixing portion 520 and less than the thickness of the second fixing portion 530, and a gap is formed between the plugging end of the adapting PCB board 100 and the inner housing 700, so that the connector can be plugged with other interfaces at the gap to achieve corresponding functions, such as a charging function or a data transmission function. In some embodiments, the outer surface of the positioning portion 510 abuts against the hole wall of the through hole 710 of the inner housing, so that the base 500 can more stably position the inner housing 700 to prevent the inner housing 700 from being separated from the base 500.

In some embodiments, the material of the inner housing 700 is iron. Because the strength and hardness of the inner case 700 are greater, it is not easily deformed, and the plugging end of the adapting PCB 100 can be better protected.

As shown in fig. 2, in some embodiments, the number of the plurality of first terminals 200 is seven, the number of the plurality of second terminals 300 is seven, the number of the plurality of third terminals 400 is eight, and each of the first terminals 200 is electrically connected to one of the second terminals 300 and at least one of the third terminals 400. It will be appreciated that one or both of the third terminals 300 may be electrically connected together by first and second terminals 200, 300 being electrically connected together. It should be noted that, when the first terminal 200 and the second terminal 300 are soldered to two surfaces of the plugging end of the interposer PCB board 100, respectively, to achieve the electrical connection between the first terminal 200 and the second terminal 300, the first terminal 200 and the second terminal 300 with the same function are correspondingly electrically connected together. For example, as shown in fig. 6, the d+ (positive differential signal) terminal in the first terminal 200 is electrically connected with the d+ terminal in the corresponding second terminal 300, and the first terminal 200 and the second terminal 300 may share the d+ terminal in the third terminal 400. Terminals for other functions, such as GND (ground) terminal, vbus (power) terminal, D- (negative differential signal) terminal, CC1 (configuration channel) terminal, and CC2 terminal, shown in fig. 6, are also provided, and the connection manner of the terminals for various functions is the same as that of the GND terminal, and is not repeated here. Through this kind of connected mode, when carrying out the welding with the switching PCB board 100 of connector and butt joint, only need with the less third terminal 400 welding of quantity to the PCB board 100 of butt joint can, not only reduced the paster degree of difficulty, improved welding efficiency, still saved the welding area with the PCB board 100 of connector butt joint. It should be noted that, the number of the first terminals 200, the number of the second terminals 300 and the number of the third terminals 400 may be set as required, but the number of the third terminals 400 is ensured to be smaller than the sum of the number of the first terminals 200 and the number of the second terminals 300, so that the difficulty in soldering the connector and the other docked PCB boards 100 can be reduced. For example, as shown in fig. 6, the CC1 terminal of the first terminal 200 and the CC2 terminal of the second terminal 300 may share the CC1 terminal and the CC2 terminal of the third terminal 400, in which case the number of the plurality of third terminals 400 is eight; if the CC1 terminals of the first terminal 200 and the second terminal 300 in fig. 6 share only the CC1 terminal of the third terminal 400, the number of the third terminals 400 is seven. The number of the first terminals 200 and the number of the second terminals 300 may be 12, the number of the third terminals 400 may be 12, and the number of the terminals may be variously adjusted according to the functions implemented by the connector, which is not shown here.

Both sides of the first housing 810 and both sides of the second housing 820 are fixed together by a laser welding technique or a bolt. In some embodiments, the outer shell 800 is made of iron, and the iron shell is hard to deform due to high hardness and strength, so that the inner shell 700 and the structures in the inner shell 700 can be better protected.

The socket 500 is integrally injection molded with the adapting PCB 100 by IM (Insert Molding) technology. In the injection molding process, the transfer PCB 100 with the plurality of first terminals 200, the plurality of second terminals 300 and the plurality of third terminals 400 fixed thereon is placed in an injection mold, then an injection molding material is injected onto the surface of the transfer PCB 100, the shape formed by the plastic in the mold is the shape of the base 500, and after injection molding, a structure in which the injection molding material and the transfer PCB 100 are integrated together can be obtained, and meanwhile, the injection molding material does not cover the first terminals 200 and the second terminals 300.

The inner housing 700 is sleeved on the outer surface of the positioning portion 510, and the inner housing 700 abuts against the second fixing portion 530 in the plugging direction of the connector. In some embodiments, after the adapting PCB 100 is integrally injection-molded with the base 500, the inner housing 700 is sleeved on the positioning portion 510. It will be appreciated that after the inner housing 700 is assembled, the mating end of the adapter PCB board 100 is positioned within the inner housing 700 and exposed from the opening of the inner housing 700 away from the base 500.

As shown in fig. 5, in some embodiments, the connector manufacturing method further includes sheathing the outer housing 800 over the outer surface of the inner housing 700. The outer case 800 and the inner case 700 may be fixed together by a laser welding technique, and in this fixing manner, the outer case 800 and the inner case 700 may be combined more firmly and not easily separated.

In the method for manufacturing the connector provided by the embodiment of the application, the first terminal 200, the second terminal 300 and the third terminal 300 are respectively installed on the adapting PCB, and then the adapting PCB 100 is placed in the injection mold to form the base 500 integrated with the adapting PCB 100, so that the manufacturing process is simple, and the bonding strength between the adapting PCB 100 and the base 500 is improved. Meanwhile, in the connector manufactured using the method, since the corresponding first and second terminals 200 and 300 are electrically connected to the corresponding third terminals 400 through the transfer PCB board 100, the current or signal inputted to the first and second terminals 200 and 300 may be transferred by the transfer PCB board 100 and then outputted through the third terminals 400. The corresponding first terminals 200 and second terminals 300 can share the third terminals 400, so that the number of the third terminals 400 is less than the sum of the numbers of the first terminals 200 and the second terminals 300, and when the connector is welded and fixed with the PCB in butt joint, the number of the terminals required to be welded on the PCB in butt joint is less, thereby not only reducing the patch difficulty, but also saving the welding area of the PCB in butt joint with the connector.

The embodiment of the application also provides electronic equipment, which comprises any connector. It should be noted that the connector may be a charging interface connector or a data transmission interface connector on the electronic device. Referring to fig. 1, the connector includes a transfer PCB 100, a plurality of first terminals 200, a plurality of second terminals 300, a plurality of third terminals 400, and a housing 500. The adapting PCB board 100 is fixed to the base 500. The plurality of first terminals 200 and the plurality of second terminals 300 are respectively mounted on both surfaces of the plugging end of the adapting PCB board 100. The third terminals 400 are mounted at the fixed end of the adapting PCB 100 and extend through the base 500. The corresponding first and second terminals 200 and 300 are electrically connected to the corresponding third terminals 400 through the relay PCB board 100.

In the connector provided by the embodiment of the application, the fixed end of the adapting PCB board 100 is fixed on the base 500, the plurality of first terminals 200 and the plurality of second terminals 300 are respectively mounted on two surfaces of the plugging end of the adapting PCB board 100, and the plurality of third terminals 400 are fixed on the fixed end of the adapting PCB board 100 and extend out through the base 500. Since the corresponding first and second terminals 200 and 300 are electrically connected to the corresponding third terminals 400 through the transit PCB 100, the current or signal input to the first and second terminals 200 and 300 can be transited by the transit PCB 100 and then output through the third terminals 400. That is, the corresponding first terminals 200 and second terminals 300 may share the third terminals 400, so that the number of the third terminals 400 is less than the sum of the numbers of the first terminals 200 and second terminals 300, and thus, when the connector is soldered and fixed to the PCB board to which the connector is mated, the number of terminals to be soldered on the mated PCB board is less, so that the difficulty of mounting the chip is reduced, and the soldering area of the PCB board to which the connector is mated is saved. In addition, since the soldering area required for the PCB 100 to be docked with the connector is reduced, the PCB to be docked with the connector has a larger area to arrange other electronic devices, thereby facilitating the internal space layout of the electronic device, or the area of the PCB itself to be docked with the connector can be reduced, thereby facilitating the light and thin of the electronic device. Other features and advantages of the connector may also provide corresponding advantages to the electronic device. For example, extended connector life may also enhance the durability of the electronic device.
