Description

Technical Field

[0001] This utility model relates to a socket electrical connector, and more particularly to a combined socket electrical connector. Background Technology

[0002] Most computer products or consumer electronics products are now equipped with sockets and electrical connectors that conform to communication standards (such as USB Type-C) for users to transfer data or charge their devices.

[0003] Please see Figure 8 As shown, a motherboard 81 and a female connector 82 are disposed inside the casing 80 of a computer product. The female connector 82 can be first soldered onto a circuit board 821, and then a ribbon cable 83 is soldered to the circuit board 821 of the connector 82 and the motherboard 81 respectively to form an electrical connection. The socket of the female connector 82 is exposed outside the casing 80 for use with a matching male connector (not shown in the figure).

[0004] As can be seen from the above, the socket connector is located inside the housing 80 and soldered onto the circuit board 821, which in turn is soldered to the ribbon cable 83. Since the socket connector 82 is frequently used in conjunction with the male connector, its failure rate is higher than that of other hardware components in the computer product. If it fails and needs to be replaced for repair, the housing 80 must first be opened, and the solder joints of the circuit board 821 or the ribbon cable must be desoldered before it can be removed from the motherboard 81 for replacement. This replacement procedure is too labor-intensive and expensive and needs further improvement. Utility Model Content

[0005] In view of the disadvantage that existing socket electrical connectors are not easy to replace, the purpose of this utility model is to propose a combined socket electrical connector for quick replacement of socket electrical connectors.

[0006] The main technical means used to achieve the above objectives is to make the combined socket connector include:

[0007] A power connection socket, including:

[0008] A metal casing with a front opening;

[0009] A first insulator is disposed in the metal housing, and a tongue is provided facing the front opening of the metal housing; and

[0010] Two first metal terminal groups are respectively arranged side by side on two opposite upper and lower surfaces of the tongue of the first insulator, and the rear contact portions of multiple first metal terminals of the two first metal terminal groups extend backward out of the first insulator and are arranged in two rows at intervals.

[0011] A soldering socket, selectively plugged into the electrical connection socket, and comprising:

[0012] A second insulator; and

[0013] Multiple second metal terminals are arranged in double rows at intervals within the second insulator, with the front portion of each second metal terminal exposed outside the second insulator and its solder feet extending through the second insulator; wherein, when the electrical connector is inserted into the soldering socket, the rear contact portion of the first metal terminals directly contacts the front portion of the second metal terminals; and

[0014] A locking element is movably disposed on the soldering base to selectively lock the electrical connection socket and the insertion point of the soldering base.

[0015] The second insulator has two grooves recessed on its two opposite outer sides; and the locking member integrally includes a horizontal plate and two opposite straight plates. The horizontal plate is positioned at intervals on the top surface of the second insulator, and the free ends of the two straight plates are bent toward the two grooves to be inserted into the corresponding grooves, so that the locking member can move horizontally along the two grooves.

[0016] The two grooves extend out from the rear side of the second insulator; each of the outer sides of the second insulator forms a long groove above the groove; and the long groove on the inner side of each straight plate facing the outer side of the second insulator forms a stop portion that elastically abuts against the long groove.

[0017] The electrical connection socket further includes a metal cover disposed on the metal housing; wherein the top surface of the metal cover has at least one protrusion.

[0018] The second insulator has two recessed slots on its two opposite outer sides; the locking member includes a horizontal plate and two opposite straight plates, which are pivotally connected to the second insulator; and each straight plate forms a protrusion inward to engage with the slot.

[0019] The electrical connection socket further includes a metal cover disposed on the metal housing; wherein the top surface of the metal cover has at least one protrusion.

[0020] The metal casing has two wings extending horizontally outward from its top surface to the rear and two opposite sides; the top surface of the second insulator has two recesses corresponding to the two wings for the two wings to be engaged; and the horizontal plate of the locking member is integrally bent downward near the two vertical plates to form a second elastic plate to press against the two wings of the metal casing.

[0021] In this locking member, the horizontal plate corresponds to at least one protrusion to form at least one engaging groove.

[0022] The front part of the second metal terminal is elastic. When the electrical connection socket is inserted into the soldering base, the rear contact part of each of the first metal terminals presses against the front part of its corresponding second metal terminal.

[0023] The two first metal terminal groups include twenty-four first metal terminals conforming to the USB Type C standard specification. The terminal spacing between two adjacent first metal terminals is 0.5mm, and the terminal spacing between two adjacent second metal terminals is not less than 0.5mm. The maximum width of each second metal terminal is 0.12mm or more.

[0024] The second insulator is fitted with multiple metal support plates that extend from its bottom surface.

[0025] The second insulator includes: a frame; and a connecting block for the second metal terminals to be arranged in two rows at intervals, the connecting block together with the second metal terminals being disposed in the frame; wherein the solder feet of the second metal terminals further extend out from the frame.

[0026] The rear contact portion that passes through the first insulator is arranged in two rows, staggered front and back, with intervals between them. The height difference between the rear contact portion in the upper row and the rear contact portion in the lower row is 0.3 mm, and the front-to-back distance between them is 0.5 mm.

[0027] As described above, the present invention's modular socket connector mainly comprises an electrical connection socket, a soldering base, and a locking component. In actual use, the soldering base is used to solder to a circuit board or ribbon cable, and the electrical connection socket is inserted into the soldering base, with the locking component securing the two together to maintain stability. If maintenance is required, the electrical connection socket can be directly removed from the soldering base for replacement, significantly reducing the time required to replace the electrical connection socket.

[0060] This utility model improves the female connector. The following describes the technology of this invention in detail with reference to several embodiments and drawings.

[0061] Please refer to the following first. Figure 1 As shown, the first embodiment of the socket connector 1 of this utility model includes an electrical connection socket 10, a soldering base 40, and a locking member 60; wherein the electrical connection socket 10 is selectively plugged into the soldering base 40, the soldering base 40 is used to solder to a circuit board 70 or a ribbon cable (not shown in the figure), and the locking member 60 is movably disposed on the soldering base 40 to selectively lock the plug-in point between the electrical connection socket 10 and the soldering base 40.

[0062] Please refer to the following: Figure 2 and Figure 3 The aforementioned electrical connection socket 10 includes a metal housing 13, a first insulator 11, and two first metal terminal groups 20 and 30. The metal housing 13 includes a front opening 131; in one embodiment, the top surface of the metal housing 13 has two wings 132 extending horizontally outwards to opposite sides. The first insulator 11 is disposed within the metal housing 13 and has a tongue 12 facing the front opening 131. For example... Figure 5 As shown, the tongue 12 has two opposing upper surfaces 121 and lower surfaces 122. The two first metal terminal groups 20 and 30 are respectively arranged side-by-side on the two opposing upper surfaces 121 and lower surfaces 122 of the tongue 12. The rear contact portions 22 and 32 of multiple first metal terminals 21 and 31 of the two first metal terminal groups 20 and 30 extend rearward through the first insulator 11, arranged in two rows, staggered front to back, and spaced apart. In one embodiment, as... Figure 3 and Figure 5As shown, the first metal terminal group 20 located on the upper surface 121 of the tongue 12 has its rear contact portions 22 protruding from the first insulator 11 arranged in a first row. The first metal terminal group 30 located on the lower surface 122 of the tongue 12 has its rear contact portions 32 protruding from the first insulator 11 arranged in a second row and is recessed from the first row, and is located below the first row. The height difference between the rear contact portions 22 in the first row and the rear contact portions 32 in the second row can be approximately 0.3 mm, and the front-to-back distance between them is approximately 0.5 mm. In one embodiment, the electrical connection socket 10 is a USB Type C connector, and therefore may include twenty-four first metal terminals 21, 31, wherein the terminal spacing between two adjacent first metal terminals is 0.5 mm.

[0063] The aforementioned welding base 40 includes a second insulator 41 and a plurality of second metal terminals 50. These second metal terminals 50 are arranged in a double row within the second insulator 41, corresponding to the two first metal terminal groups 20 and 30. Figure 2 and Figure 5 As shown, the front portion 51 of each of the second metal terminals 50 is exposed from the second insulator 41. These exposed front portions 51 are arranged in pairs, staggered front and back, and spaced apart, while their solder feet 52 protrude from the second insulator 41. When the electrical connection socket 10 is inserted into the soldering base 40 from top to bottom or from front to back, its rear contact portions 22 and 32 directly and respectively contact the front portions 51 of the second metal terminals 50. In this embodiment, the front portion 51 of each second metal terminal 50 is bent into an elastic portion. When the electrical connector 10 is inserted into the soldering base 40, the rear contact portions 22 and 32 of each first metal terminal 21 and 31 press against the elastic front portion 51 of its corresponding second metal terminal 50. When the electrical connector 10 is removed from the soldering base 40, the rear contact portions 22 and 32 of the first metal terminals 21 and 31 no longer press against the front portion 51 of the second metal terminal 50 and return to their original positions. In one embodiment, the terminal spacing between two adjacent second metal terminals 50 is not less than 0.5 mm, and the maximum width of each second metal terminal 50 is 0.12 mm or more.

[0064] In one embodiment, such as Figure 3 As shown, the second insulator 41 may include a connecting block 42 and a frame 43. The second metal terminals 50 are arranged in two rows, one above the other and spaced apart, within the connecting block 42, and then engaged with the connecting block 42 within the frame 43. Figure 4 As shown, two recesses 431 are formed on the top surfaces of the two sides of the frame 43, into which the two wings 132 of the metal shell are inserted. Figure 5 As shown, the solder pads 52 of the second metal terminals 50 further extend from the frame 43 to be soldered onto the circuit board 70. In another embodiment, as... Figure 3As shown, the frame 43 of the second insulator 41 is provided with multiple metal support plates 53, which protrude from its bottom surface and can be connected to a negative potential.

[0065] like Figure 1 , Figure 3 and Figure 4 As shown, the electrical connector 10 further includes a locking member 60, which locks the electrical connector 10 when it is inserted into the soldering base 40, such as... Figure 1 As shown, the locking member 60 is horizontally slidable on the second insulator 41 and locks onto the electrical connection socket 10 in a horizontally moving manner. In this embodiment, two sliding grooves 411 are formed on the two opposite outer sides of the second insulator 41. The locking member 60 integrally includes a horizontal plate 61 and two opposite straight plates 62. The free ends of the two straight plates 62 are bent toward the two sliding grooves 411 to insert into the corresponding sliding grooves 411, allowing the locking member 60 to move horizontally along the two sliding grooves 411. Since the two sliding grooves 411 extend beyond the rear side of the second insulator 41, in order to prevent the locking member 60 from falling backward during horizontal sliding, a long groove 412 can be formed on each of the outer sides of the second insulator 41, positioned above the sliding groove 411. The long groove 412 on the inner side of each straight plate 62 facing the outer side of the second insulator 41 forms a stop portion 621 inward, such as... Figure 1 As shown, the abutment portion 621 elastically abuts against the elongated groove 412, and stops when the locking member 60 moves horizontally rearward until its abutment portion 621 abuts against the rear wall surface of the elongated groove 412. In one embodiment, the locking member 60 is formed by bending a metal plate, and each abutment portion 621 is integrally bent inward from its corresponding straight plate 62.

[0066] Please see again Figure 1 and Figure 6 As shown, the electrical connection socket 10 further includes a metal cover 14 disposed on the metal housing 13. The top surface 141 of the metal cover 14 has at least one protrusion 142, and the horizontal plate 61 of the locking member 60 forms at least one engaging groove 611 corresponding to the at least one protrusion 142. Figure 1 As shown, when the locking member 60 is pushed forward, the engaging groove 611 moves closer to the protrusion 142 until the protrusion 142 enters the engaging groove 611, as... Figure 4 As shown; at this time, as Figure 1 As shown, the locking member 60 is located at the insertion point of the electrical connection socket 10 and the soldering base 40. In addition, the horizontal plate 61 of the locking member 60 is integrally bent downward into a second elastic plate 612 near the two straight plates 62 to press against the two wings 132 of the metal housing 13 of the electrical connection socket 10.

[0067] For example Figure 7As shown, in another embodiment, the locking member 60' is pivotally connected to the second insulator 41 and is rotatably locked at the insertion point between the electrical connector 10 and the solder pad 40. Specifically, the two straight plates 62 of the locking member 60' are pivotally connected to the two opposite outer sides and near the rear side of the second insulator 41, and are pivoted upwards to expose the front part (not shown) of the second metal terminals of the solder pad 40, allowing the electrical connector 10 to be smoothly inserted. Then, the locking member 60' is pivoted downwards and locked at the insertion point between the electrical connector 10 and the solder pad 40 to securely lock the electrical connector 10 onto the solder pad 40. Furthermore, each of the straight plates 62 forms an inwardly protrusion 622, and the two opposite sides of the second insulator 41 form a groove 413 corresponding to the two protrusions 622. When the locking member 60' pivots downward, the two protrusions 622 are engaged in the two grooves 413. The following further explains that the combined socket electrical connector 1 of this utility model further provides a locking function, that is, further ensures the stability of the insertion of the electrical connection socket 10 and the soldering base 40.

[0068] In summary, in practical use, the soldering socket of this utility model is used to solder to a circuit board or ribbon cable, while the electrical connector is inserted into the soldering socket and secured by the locking member to maintain a stable assembly. This ensures that the electrical connector will not detach from the soldering socket when the matching electrical connector plug is repeatedly inserted into it. Furthermore, when the electrical connector is damaged after long-term use, simply removing the electrical connector from the soldering socket allows its multiple first metal terminals to easily separate from the multiple second metal terminals of the soldering socket, enabling direct replacement and significantly reducing the time required to replace the electrical connector.

[0069] The above description is merely an embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above by way of embodiment, it is not intended to limit the present utility model. Anyone skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.

[0070] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the claims of this utility model.
