Description

Technical Field

[0001] The present invention relates to a connection device, and in particular to an electrical connection device and an electrical connector. Background Art

[0002] See Figure 1 , is a conventional electrical connector 1, comprising a housing 11 defining a mounting slot 110 and a conductive unit 12 disposed within the mounting slot 110. The conductive unit 12 is constructed of a single metal layer structure and includes a plurality of conductive arms 121 extending away from the housing 11 and adapted to connect to corresponding electrical connection points.

[0003] When the conductive arms 121 come into contact with the corresponding electrical connection points, they are subject to external forces such as pressure and friction. Therefore, if the electrical connector 1 is frequently used for testing or plugging, it is inevitable that any of the conductive arms 121 may become damaged due to exceeding their deformation margin or prolonged exposure to external forces. However, because the conductive unit 12 is a monolithic, layered structure, even if only a single conductive arm 121 is damaged, the entire conductive unit 12 must be replaced to complete the necessary repair. This is not an ideal technical solution for today's high-tech industry, which prioritizes cost-effectiveness and sustainable operations. Summary of the Invention

[0004] The object of the present invention is to provide an electrical connection device and an electrical connector that use multiple module components to form an electrical conductive structure.

[0005] The electrical connection device of the present invention is suitable for being arranged in a packaging unit to be assembled into an electrical connector, and comprises a substrate, a conducting unit and a cover plate covering the conducting unit.

[0006] The substrate includes a top surface, a bottom surface located at an opposite side of the top surface, at least one mounting groove recessed in the top surface, and a first through hole penetrating the top surface and the bottom surface.

[0007] The guide unit includes a plurality of inner core modules disposed in the at least one mounting groove. Each inner core module has a base and a plurality of connecting arms extending outward from the base and capable of generating elastic deformation toward the base.

[0008] The cover includes a plate body, a plurality of slots extending through the plate body for the connecting arms to extend through, and a second through-hole extending through the plate body and aligned with the first through-hole. The second through-hole and the first through-hole together form a reserved receptacle suitable for inserting an external connector and establishing an electrical connection with the conductive unit or the packaging unit.

[0009] In the electrical connection device of the present invention, the extending grooves of the cover plate are respectively used for the connecting arms to extend therethrough.

[0010] In the electrical connection device of the present invention, each of the through-and-through slots of the cover plate extends along an extension direction and allows a plurality of the connecting arms to extend therethrough.

[0011] In the electrical connection device of the present invention, the through-extension grooves of the cover plate are spaced apart from each other along a spacing direction perpendicular to the extending direction.

[0012] In the electrical connection device described in the present invention, at least a portion of the connecting arm of each of the inner core modules extends toward the substrate, and the substrate further includes a plurality of bottom through-grooves extending from the at least one mounting groove to the bottom surface and for allowing the connecting arm to extend therethrough.

[0013] In the electrical connection device of the present invention, each of the bottom through-grooves extends along an extension direction, and a cross-sectional width of each of the bottom through-grooves along the extension direction gradually narrows in a direction away from the respective base.

[0014] In the electrical connection device of the present invention, the mounting slot is formed with a plurality of concave areas spaced apart from each other, and each of the inner core modules further has a plurality of protruding portions protruding from the base and used to be respectively disposed in the concave areas.

[0017] The beneficial effects of the present invention are that, in addition to being able to be configured as the electrical connector of the present invention, the electrical connection device of the present invention can further utilize the reserved jack to expand the connection requirements of the external connector, depending on the basic purpose of the electrical connection, effectively improving versatility. Furthermore, because the conductive connection unit includes the inner core module, not only can the inner core module be freely configured to meet the corresponding connection requirements, but if the connecting arm is damaged, only the corresponding inner core module needs to be replaced, rather than the entire conductive connection unit, resulting in more economical maintenance costs.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0026] See Figure 2 , an embodiment of the electrical connection device P of the present invention, this embodiment of the device is arranged in a packaging unit 7 (see Figure 7 ) are assembled into an electrical connector C of the present invention, and include a substrate 2, a conducting unit 3 disposed on the substrate 2 and used to form an electrical connection structure, and a cover 4 covering the conducting unit 3.

[0027] The base plate 2 includes a top surface 21, a bottom surface 22 located opposite to the top surface 21, a plurality of mounting grooves 23 recessed in the top surface 21, a first through hole 24 penetrating the top surface 21 and the bottom surface 22, and a plurality of bottom through grooves 25 extending from each mounting groove 23 to the bottom surface 22. The distribution, number, and shape of the mounting grooves 23 on the base plate 2 are designed according to the configuration requirements of the conductive unit 3. Each bottom through groove 25 extends along an extension direction D, and as shown in FIG. Figure 3 As shown, the cross-sectional width of each bottom through-groove 25 along the extending direction D gradually narrows away from the respective base 311 .

[0028] See also Figures 2 to 4The conductive unit 3 includes a plurality of inner core modules 31 disposed in the mounting slots 23. Specifically, in order to form a specific contact distribution according to connection requirements, the inner core modules 31 can also have various forms. The installation of the inner core modules 31 can be carried out by installing one inner core module 31 in a single mounting slot 23, or by installing multiple inner core modules 31 in one mounting slot 23, depending on the difference in form. Each inner core module 31 has a base 311 made of a dielectric material, and a plurality of connecting arms 312 extending outward from the base 311, made of a conductive material, and capable of elastic deformation in a direction toward the base 311. Part of the connecting arm 312 of each inner core module 31 extends toward the cover plate 4, while the other part extends toward the base plate 2. In other words, in this embodiment of the device, the general use case in which the connecting arms 312 extend toward opposite sides is used for explanation.

[0029] Specifically, the base 311 of the inner core module 31 can be designed to match the shape of the corresponding mounting slot 23 so that the base 311 is positioned in the mounting slot 23 in a nearly tight fit manner. Figure 4 As shown, since the stable setting of the base 311 will directly affect the position accuracy of the connecting arm 312, in some embodiments, the inner core module 31 also has a plurality of protruding portions 319 protruding from the base 311, thereby positioning with the concave area 239 formed by the installation groove 23, and forming a concave-convex locking structure to further optimize the installation stability of the inner core module 31.

[0030] It is worth mentioning that when the corresponding connecting arm 312 is extended and placed in the bottom through slot 25, the bottom through slot 25 is used as Figure 3 The gradually narrowing shape allows the bottom through-groove 25 to guide the connecting arm 312 even if it is not completely straight due to manufacturing tolerances, assembly errors, or other factors, so that the connecting arm 312 can better conform to the default contact position at the end point away from the base 311.

[0031] The cover plate 4 includes a plate body 41, a plurality of through-grooves 42 passing through the plate body 41 and for the connecting arms 312 to extend through, and a second through-hole 43 passing through the plate body 41 and aligned with the first through-hole 24. The connecting arms 312 of the conductive unit 3, which face the base plate 2 and the cover plate 4 in two directions, extend through the corresponding bottom through-grooves 25 and the through-grooves 42, respectively. Figure 5The second through hole 43 and the first through hole 24 together form a reserved socket H suitable for inserting an external connector (not shown) and achieving electrical connection with the conductive unit 3 or the packaging unit 7.

[0032] Continue reading Figure 5 and cooperate with Figure 3 The connecting arm 312 of the present embodiment of the device can achieve electrical connection with the corresponding electrical connection point through the bottom through-groove 25 and the through-groove 42. The characteristic of the connecting arm 312 being able to generate elastic deformation allows it to be connected according to the commonly used pressing connection method toward the present embodiment of the device, as well as the scratch test connection requirements that are often performed in electrical tests. Accordingly, in addition to being able to freely configure a specific contact array through the inner core module 31, if part of the connecting arm 312 is damaged, part of the inner core module 31 can be replaced. It does have better versatility and application flexibility, and is conducive to related maintenance in subsequent use.

[0033] See Figure 6 , which is another embodiment of the present device, each of the through-grooves 42 extends along the extension direction D, and the through-grooves 42 are spaced apart from each other along a spacing direction A perpendicular to the extension direction D. Each through-grooves 42 allows multiple connecting arms 312 to extend through, so there is no obstruction between the connecting arms 312 within a single through-grooving slot 42. This increases the deformation margin of each connecting arm 312 along the through-grooving direction of the corresponding through-grooving slot 42, avoiding interference from physical separation structures, thereby adapting to specific detection connection requirements.

[0034] See Figure 7 and cooperate with Figure 5 ,like Figure 7 Presented is a device embodiment of the electrical connector C of the present invention, which includes the packaging unit 7 and the device embodiment of the electrical connection device P of the present invention. The packaging unit 7 includes a shell 71 that defines an inner space 710 and two connecting wires 72 that pass through the inner space 710. The shell 71 has a third through hole 711 that is penetrating and aligns with the first through hole 24 and the second through hole 43 to form the reserved socket H. The device embodiment is arranged in the inner space 710 and is electrically connected to the connecting wire 72, thereby forming the main conductive structure of the device embodiment. In addition, through the reserved socket H, the device embodiment can also be connected to additional external connectors to accommodate possible functional expansion or other connection requirements.

[0035] The above description is only a preferred embodiment of the present invention, but it is not intended to limit the scope of the present invention. Anyone familiar with this technology can make further improvements and changes on this basis without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims of this application.
