Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an electrical connection assembly. Background Art

[0002] Connectors, also known as connectors and sockets in China, generally refer to electrical connectors, which are devices that connect two active components to transmit current or signals. The male and female ends of the connector can transmit information or current through contact.

[0003] Connectors currently available on the market include a wide variety of types for various scenarios, such as the widely used Type-C connector. However, while commonly used Type-C connectors are easy to plug and unplug, they lack a retaining structure and are prone to loosening. This can lead to low connection reliability, especially in environments with motion or vibration, resulting in a poor user experience. Utility Model Content

[0004] In view of this, the purpose of the present invention is to design an electrical connection component, which, by setting a snap-on component, has a mechanical fixing function on the basis of electrical conduction, ensures that the connection between the male connector and the female connector is firm and reliable, maintains the stability of electrical conduction, improves the mechanical and electrical performance of the connector, and thus enhances the user experience.

[0005] The utility model provides an electrical connection assembly, which is installed on an electrical product structure and includes: a female connector and a male connector. The female connector is fixedly connected to the housing of the electrical product structure (preferably, the female connector is installed in the middle of the housing of the electrical product structure), and the male connector can be inserted and connected to the female connector; the male connector is installed and fixed in a plug, and the plug includes: a lower plug shell and an upper plug shell. The upper plug shell is detachably connected to the lower plug shell, and two groups of snap-on assemblies are symmetrically installed in the lower plug shell.

[0006] Specifically, the female connector is installed at the end of the electrical product, and the male connector provides power to the electrical product or provides other electrical signals, such as updating program software.

[0007] Furthermore, the buckle assembly includes: a rotating shaft, a torsion spring, and a buckle; the rotating shaft is rotatably set in the slot hole of the lower shell of the plug, and the buckle is hingedly connected to the rotating shaft; the torsion spring is sleeved in the rotating shaft, and the two legs of the torsion spring are respectively abutted against the buckle and the lower shell of the plug.

[0008] Specifically, the rotating shaft is installed in the slot of the lower shell of the plug, and the shaft hole fits tightly; then the buckle and torsion spring are installed on the rotating shaft together, and the rotating shaft, torsion spring and buckle on both sides are installed in this way; one leg of the torsion spring presses against the buckle, and the other leg presses against the lower shell of the plug, so that the torsion spring always applies force to the two sides of the plug, causing the buckle to separate to the two sides of the plug; pinch the buckle with your hand, and the buckle rotates with the rotating shaft as the center of the circle, and the front end of the buckle approaches the middle of the plug.

[0009] Furthermore, the male connector is installed in a slot in the lower housing of the plug. A flexible circuit board (FPC) is welded to the male connector, and a cable tail is welded to the FPC. The cable tail is installed in the cable slot of the lower housing of the plug. The side of the cable tail close to the FPC (the inner side of the plug) is provided with a rectangular structure. The rectangular structure prevents the cable from rotating and breaking the internal leads.

[0010] Specifically, each wire of the cable tail tube is soldered to a soldering pad of the FPC, and the connector may be 8-pin, 10-pin, 6-pin, or 4-pin.

[0011] Furthermore, a circular hole is formed on the interface between the lower and upper shells of the plug, through which the cable tail tube extends. The length and width of the rectangular structure are greater than the diameter of the circular hole. This prevents the cable tail tube from being pulled from the outside of the plug and separated from the plug shell.

[0012] Furthermore, a three-dimensional closed annular groove is provided at the junction of the electrical product structural housing and the connector female seat. The three-dimensional closed annular groove is used for spot coating of semi-solid glue, which can achieve a good waterproof effect.

[0013] Furthermore, a product structural member is provided on the electrical product structural housing at the location where it mates with the three-dimensional closed annular groove. The product structural member is provided with a rib, and waterproof glue is filled between the rib and the three-dimensional closed annular groove. The filling glue can effectively prevent water from entering the electrical product structural housing. A groove is provided on the product structural member at the location where it mates with the connector female socket, and waterproof glue is applied in the groove. Applying waterproof glue can further waterproof the connector.

[0014] Preferably, fixing glue or structural glue is applied to other areas where the waterproof glue is applied, and then the product structural component is installed from top to bottom and firmly bonded to the product shell.

[0015] Optionally, if the product shell and product structural parts are made of plastic materials, ABS glue, AB glue or instant glue can also be applied to other areas where the waterproof glue is applied.

[0016] Specifically, the female connector includes: a female base and a flat pin, and the male connector includes: a male base and a spring pin; the flat pin is inserted into the corresponding hole of the female base and slightly squeezes the corresponding hole of the female base to achieve the effect of being assembled in place; the raw material of the female base can be engineering plastic, that is, it can be deformed very slightly. The raw material of the flat pin can be metal, such as copper, for electrical conduction. The spring pin is inserted into the corresponding hole of the male base and slightly squeezes the corresponding hole of the male base to achieve the effect of being assembled in place. The front end of the spring pin can rebound when pressurized, achieving the effect of contact and rebound conduction with the flat pin of the female. The raw material of the male base can be engineering plastic, that is, it can be deformed very slightly. The raw material of the spring pin can be metal, such as copper, with a built-in spring, and the front end can rebound when pressurized for electrical conduction.

[0017] In the direction of plug insertion, when the plug's buckle engages the rectangular groove of the lower shell, the spring pin of the male connector on the plug end is compressed by about 2 / 3 of its stroke, effectively ensuring good contact between the spring pin and the flat pin, and ensuring that the spring pin will not be damaged by excessive compression.

[0018] Furthermore, two symmetrical rectangular grooves are provided on both sides of the electrical product structure housing at the mating position with the plug, and the buckle is inserted into the rectangular grooves, and the rectangular grooves accommodate the buckle.

[0019] When inserting the plug, the beveled angle of the buckle on the plug end and the guide angle of the product housing prevent the buckle from being damaged during insertion. When removing the plug, the buckle must be pressed to remove it. The connection is firm and reliable, and the insertion and removal operations are convenient and quick.

[0020] Furthermore, a hexagonal groove is provided on the outer side of the electrical product structural shell (preferably symmetrical with respect to the middle of the connector female seat), and the front end of the plug is matched with a small gap between the inner side surface of the hexagonal groove, so that when the plug is inserted into the electrical product structural shell, the spring pin of the connector male head and the flat pin of the connector female seat ensure contact and conduction; and it also prevents the plug from being inserted upside down, which has an anti-mock effect.

[0021] Furthermore, the plug upper shell is fixedly connected to the plug lower shell by threads. Preferably, the plug upper shell is mounted on the plug lower shell using multiple (preferably 3) screws, which ensures a firm connection and reliable connection.

[0022] Furthermore, another flexible circuit board (FPC) is welded to the connector socket. One end of this other FPC is welded to another circuit board within the electrical product housing or connected to the other circuit board via another connector. This other FPC has a high wiring density, is lightweight, thin, and has good bendability. It can be bent within the limited space within the electrical product housing to achieve good electrical connectivity.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] The electrical connection assembly provided by the present invention has a simple and reasonable component module structure and strong integrity.

Figure 1 、 2 As shown, the female connector 1 is fixedly connected to the center of the inner side of the electrical product housing 10, and the male connector 2 is inserted and connected to the female connector 1; the male connector 2 provides power to the electrical product or provides other electrical signals, such as updating program software. The male connector 2 is installed in the slot of the lower shell 7 of the plug, as shown in FIG. Figure 3 As shown, the male connector 2 is welded with a flexible circuit board FPC 9, and the flexible circuit board FPC 9 is welded with a cable tail tube 8; the cable tail tube 8 is installed in the cable groove of the plug lower shell 7, and each wire of the cable tail tube 8 is welded to the pad of the FPC. In this embodiment, the connector is 8-pin. The side of the cable tail tube 8 close to the FPC (the inner side of the plug) is provided with a rectangular structure (such as Figure 4 The rectangular structure prevents the cable from rotating and breaking the internal leads.

[0047] like Figure 6 As shown, the plug upper shell 6 is mounted on the plug lower shell 7 using three screws 11, which is firmly combined and connected reliably. Two sets of snap-fit components are symmetrically installed in the plug lower shell 7. Figure 5 As shown, the buckle assembly includes: a rotating shaft 3, a torsion spring 4, and a buckle 5; the rotating shaft 3 is rotatably set in the slot hole of the lower shell of the plug, and the buckle 5 is hingedly connected to the rotating shaft 3; the torsion spring 4 is sleeved in the rotating shaft 3, and the two legs of the torsion spring 4 are respectively abutted against the buckle 5 and the lower shell of the plug.

[0048] The rotating shaft 3 is installed in the slot hole of the lower shell 7 of the plug, and the shaft hole fits tightly; then the buckle 5 and the torsion spring 4 are installed on the rotating shaft 3 together, and the rotating shaft 3, torsion spring 4 and buckle 5 on both sides are installed in place; one leg of the torsion spring 4 is against the buckle 5, and the other leg is against the lower shell 7 of the plug, so that the torsion spring 4 always applies force to the buckle 5 on both sides of the plug, so that the buckle 5 is separated to both sides of the plug; pinch the buckle 5 with your hand, and the buckle 5 rotates with the rotating shaft 3 as the center, and the front end of the buckle 5 approaches the middle of the plug.

[0049] A circular hole is formed on the joint surface of the plug lower shell 7 and the plug upper shell 6, and the cable tail tube 8 extends from the circular hole. The length and width of the rectangular structure are larger than the diameter of the circular hole, which prevents the cable tail tube 8 from being pulled from the outside of the plug, causing the cable tail tube 8 to be pulled out and separated from the plug shell.

[0050] like Figure 9 、 10 As shown, a three-dimensional closed annular groove 12 is provided at the joint between the electrical product structure housing 10 and the connector female seat 1 (as shown in FIG. Figure 7 As shown), the three-dimensional closed annular groove 12 is used for spot coating of semi-solid glue, which can achieve a good waterproof effect. A product structural part 13 is provided on the electrical product structural shell 10 at the matching position with the three-dimensional closed annular groove 12. A convex rib is provided on the product structural part 13. An appropriate amount of semi-solid glue is filled between the convex rib and the three-dimensional closed annular groove 12 for waterproofing. The filling glue can well prevent water from entering the interior of the electrical product structural shell 10. Then the connector socket 1 is installed to the corresponding position of the electrical product structural shell 10; a groove is provided on the product structural part 13 at the matching position with the connector socket 1. Waterproof glue is spot coated in the groove to further waterproof the connector. In other areas where the waterproof glue is spot coated, retaining glue or structural glue is spot coated. Then the product structural part 13 is installed from top to bottom and firmly bonded to the electrical product structural shell 10.

[0051] The female connector 1 comprises a female base 1-1 and flat pins 1-2. The male connector 2 comprises a male base 2-1 and a spring pin 2-2. The flat pins 1-2 are inserted into corresponding holes in the female base 1-1 and slightly squeezed to secure the connector. The female base 1-1 is made of engineering plastic and can deform very slightly. The flat pins 1-2 are made of copper and provide electrical continuity. The spring pins 2-2 are inserted into corresponding holes in the male base 2-1 and slightly squeezed to secure the connector. The front end of the spring pin 2-2 rebounds when pressure is applied, allowing contact with the flat pin 1-2 of the female connector 1 and electrical continuity. The male base 2-1 is made of engineering plastic and can deform very slightly. The spring pin 2-2 is made of copper and has a built-in spring. The front end of the spring pin 2-2 rebounds when pressure is applied, ensuring electrical continuity.

[0052] Figure 11 The longitudinal section of the plug is shown when it is inserted into the housing 10 of the electrical product structure. Figure 12 It shows a cross section when the plug is inserted into the electrical product structural housing. Two symmetrical rectangular grooves are provided on both sides of the electrical product structural housing 10 where the plug is mated. The buckle 5 is inserted into the rectangular groove to accommodate the buckle 5.

[0053] In the direction of plug insertion, when the plug's buckle 5 buckles the rectangular groove of the plug's lower shell 7, the spring pin 2-2 of the connector male connector 2 at the plug end is compressed by about 2 / 3 of its stroke, effectively ensuring good contact between the spring pin 2-2 and the flat pin 1-2, and ensuring that the spring pin 2-2 will not be damaged by excessive compression.

[0054] When the plug is inserted, because of the bevel angle of the buckle 5 at the plug end and the guide angle of the electrical product structure housing 10, it is not necessary to press the buckle 5 during insertion, and the buckle 5 will not be damaged; when removing the plug, it is necessary to press the buckle 5 to remove the plug (such as Figure 13 This structure provides a firm and reliable connection, and the insertion and removal operations are quick and easy.

[0055] like Figure 8 As shown, another flexible circuit board (FPC) 15 is soldered to the connector socket 1. One end of this other FPC is soldered to another circuit board inside the electrical product housing or connected to another circuit board via another connector. This other FPC has a high wiring density, is lightweight, thin, and has good bendability. It can bend within the limited space inside the electrical product housing to achieve good electrical connectivity.

[0056] A hexagonal groove 14 is symmetrically provided in the middle of the outer side of the electrical product structural housing 10. The front end of the plug is matched with the inner side surface of the hexagonal groove 14 with a small gap, so that when the plug is inserted into the electrical product structural housing 10, the spring pins 2-2 of the connector male head 2 and the flat pins 1-2 of the connector female seat 1 ensure contact and conduction; and it also prevents the plug from being inserted upside down, which has an anti-mock effect.
