Abstract
Description
Technical Field
[0001] The utility model relates to the field of electrical connection, in particular to an electrical connector combination. Background Art
[0002] With the development trend of small and light consumer electronic products such as notebooks, tablets, and mobile phones, the design and manufacturing process of their components are becoming increasingly demanding. As the products become increasingly light and thin, the internal space becomes very narrow, which requires that the internal layout of the product must be densely packed, and the volume of each electronic component is getting smaller and smaller, and thinner and lighter, and the reliability requirements for the process technology and product connection are getting higher and higher. The existing electrical connectors are generally soldered to the circuit board through surface mount technology (SMT). This connection method is currently the most common electrical connection method. Taking the common Type C USB connector as an example, the tail of its terminal extends out of the insulating body and is soldered to the circuit board to achieve a fixed connection with the circuit board and electrical contact at the same time, while the connector's plug interface is exposed on the computer's chassis shell for mating with the docking plug. Although this method is firm, it also brings certain troubles to subsequent after-sales maintenance or technical upgrades. When the electrical connector is damaged due to frequent plugging and unplugging, the solder at the welding part must be melted by the desoldering method before the electrical connector can be removed from the circuit board for repair or replacement. The entire disassembly process is very inconvenient. Utility Model Content
[0003] The technical problem solved by the utility model is to provide an electrical connector assembly to improve the problem of inconvenience in disassembly and maintenance.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: an electrical connector combination, including a pair of connectors, an adapter, and a first on-board connector, the connectors and the first on-board connector are respectively connected to the two ends of the adapter, the adapter includes a flexible row, a second on-board connector installed on the flexible row, and a substrate integrally connected to the flexible row, the connectors are installed on the substrate, and the second on-board connector is plugged into and matched with the first on-board connector.
[0005] Furthermore, the flexible row is provided with a first connection end and a second connection end, the second onboard connector is installed on the first connection end of the flexible row, the second connection end is integrally connected to the substrate, and the substrate is a hard substrate.
[0006] Furthermore, the docking connector is a Type C USB connector, and the second onboard connector and the first onboard connector are both board-to-board connectors.
[0007] Furthermore, the docking connector includes an insulating body, a plurality of terminals received in the insulating body, a metal shell covering the surface of the insulating body, and a metal fixing cover covering the surface of the metal shell.
[0008] Furthermore, the metal fixing cover is arranged on the top wall of the metal shell and is fixed to the top wall by welding, and the metal fixing cover is provided with a pair of fixing plates protruding outward, and the fixing plates are provided with fixing holes for fixing the docking head to the substrate.
[0009] Furthermore, the overall height of the second onboard connector after being plugged and matched with the first onboard connector does not exceed 2 mm.
[0010] Compared with the prior art, the utility model is connected to the first onboard connector through an adapter and a docking head, and the frequent plugging and unplugging operations are transferred to the detachable docking head, so that the first onboard connector does not need to face frequent plugging and unplugging. When the docking head is damaged due to frequent plugging and unplugging, it is only necessary to remove the docking head together with the adapter as a whole from the first onboard connector and replace it with a new one. The disassembly process does not involve the main board circuit board, and also avoids tedious operations such as desoldering and removal of the circuit board. The maintenance and replacement process is more convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] See also Figure 1 , Figure 2 As shown, the utility model provides an electrical connector combination, including: a pair of connectors 10, an adapter 20, and a first on-board connector 30. The connectors 10 are electrically connected to the first on-board connector 30 through the adapter 20, and the first on-board connector 30 is welded and fixed to a circuit board (not shown), so that the connectors 10 can be electrically connected to the first on-board connector 30 and the circuit board (not shown) only through the adapter 20, thereby making the replacement and maintenance of the connectors 10 more convenient and quick, and the connectors 10 can be disassembled and replaced by simply pulling them out of the adapter 20 without removing the first on-board connector 30 on the circuit board.
[0014] The docking connector 10 includes an insulating body 11, a plurality of terminals 12 accommodated in the insulating body 11, a metal shell 13 covering the surface of the insulating body 11, and a metal fixing cover 14 covering the surface of the metal shell 13, wherein the insulating body 11 is provided with a docking tongue plate 15 extending forward, and the plurality of terminals 12 are distributed on the upper and lower surfaces of the docking tongue plate 15 for plugging with a docking end connector. The metal shell 13 is annular, and surrounds the periphery of the docking tongue plate 15, so as to form a docking cavity 17 on its inner side. The metal fixing cover 14 is covered on the top wall of the metal shell 13 and is fixed to the top wall by welding, and the metal fixing cover 14 is provided with a pair of fixing plates 140 protruding outward, and the fixing plates 140 are provided with fixing holes 141 for fixing the docking connector 10 to the substrate 25.
[0015] The adapter 20 includes a flexible row 22 (such as an FPC / FFC flexible board or line row), a second onboard connector 23 mounted on the flexible row 22, and a substrate 25 integrally connected to the flexible row 22. The flexible row 22 is provided with a first connection end 221 and a second connection end 222, the second onboard connector 23 is mounted on the first connection end 221 of the flexible row 22, the second connection end 222 is integrally connected to the substrate 25, the substrate 25 is a hard substrate, used to carry the docking connector 10, and the substrate 25 is provided with a contact point 26 connected to the terminal 12 of the docking connector 10, preferably, the flexible row 22 is integrally connected to the substrate 25.
[0016] The first onboard connector 30 is fixed on a circuit board (not shown) to achieve electrical connection with the circuit board, and is used to dock with the second onboard connector 23 on the flexible row 22, thereby establishing an electrical connection between the adapter 20 and the circuit board, thereby achieving conduction between the docking head 10 and the circuit board.
[0017] In a preferred embodiment of the utility model, the docking connector 10 is a Type C USB connector, and the second onboard connector 23 and the first onboard connector 30 are both board-to-board connectors (BTB). Preferably, the substrate 25 where the docking connector 10 is located can be directly fixed on the computer case, and the docking connector 10 is exposed on the surface of the case as an interface for frequent plugging and unplugging, while the first onboard connector 30 is fixed on the circuit board (such as the motherboard) inside the computer case without frequent plugging and unplugging. When the docking connector 10 is damaged, it only needs to be removed from the computer case and removed together with the adapter 20 for replacement, without the need to perform a desoldering and removal operation on the first onboard connector 30. It is particularly important that since the first onboard connector 30 and the second onboard connector 23 are both board-to-board connectors, the overall height of the two after plugging can be greatly reduced (preferably, the height does not exceed 2 mm), saving space in the case.
[0018] In summary, the utility model is connected to the first onboard connector 30 through the adapter 20 and the docking head 10, and the frequent plugging and unplugging operations are transferred to the detachable docking head 10, so that the first onboard connector 30 does not need to face frequent plugging and unplugging. Therefore, when the docking head 10 is damaged due to frequent plugging and unplugging, it is only necessary to pull out the adapter plug 21 from the first onboard connector 30, and then remove the docking head 10 together with the adapter 20 as a whole, replace them with a new docking head and adapter, and then insert them into the first onboard connector 30. The disassembly process does not involve the main board circuit board (not shown), and also avoids tedious operations such as desoldering and removal of the circuit board, and the maintenance and replacement process is more convenient and quick.
