Description

Technical Field

[0001] This utility model relates to the technical field of electrical connectors, and more particularly to a vertically mating wire-to-board electrical connector assembly. Background Technology

[0002] Existing vertical-pair wire-to-board electrical connectors include board-end connectors and wire-end connectors. Board-end connectors use blade-type flat terminals, while wire-end connectors use riveted terminals. Because riveted terminals occupy more installation space, the size of wire-end connectors must be matched to the riveted terminals, preventing miniaturization. Furthermore, the manufacturing process for wire-end connectors involves cable stripping, cable riveting to terminals, terminal assembly with the insulation structure, and assembly of the connector to the insulation structure, which is complex and costly. Board-end blade-type terminals also require assembly with the insulation structure, thus similarly resulting in complex processes and increased costs. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a vertical plug-in wire-to-board electrical connector assembly, which solves the problem that the assembly process of the existing vertical plug-in wire-to-board electrical connector is complicated and cannot be miniaturized.

[0004] An embodiment of the vertical plug-in wire-to-board electrical connector assembly of this utility model includes a board-end electrical connector and a wire-end electrical connector. The board-end electrical connector includes a first insulating structure, two first power terminals, and multiple first signal terminals.

[0020] The vertical plug-in wire-to-board electrical connector assembly of this utility model simplifies the manufacturing process by combining the first power terminal and the first signal terminal of the board-end connector with the first insulation structure through an embedded injection molding process. Furthermore, the width of the first power terminal is greater than the sum of the widths of each group of second power terminals, which increases the transmitted current and reduces contact heat generation. The second power terminal and the second signal terminal of the wire-end connector both use sheet-like terminals, which reduces the terminal spacing and thus the size of the wire-end connector, facilitating miniaturization. The spacing between adjacent second signal terminals is greater than the spacing between adjacent second power terminals, making it easier to solder the cable core wires to the wire-end connector. Moreover, the wire-end connector is soldered to the cable only after the entire assembly is completed, increasing the convenience of cooperation with manufacturing manufacturers and significantly reducing processing costs.

Detailed Implementation

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This illustrates an embodiment of the vertical plug-in wire-to-board electrical connector assembly of this utility model. The vertical plug-in wire-to-board electrical connector assembly A of this embodiment includes a board-end electrical connector 10 and a wire-end electrical connector 20. The board-end electrical connector 10 includes a first insulating structure 11, two first power terminals 12, multiple first signal terminals 13, and two metal locking tabs 14. The wire-end electrical connector 20 includes a second insulating structure 21, multiple second power terminals 22, multiple second signal terminals 23, a metal housing 24, and two power metal tabs 25.

[0039] The first insulating structure 11 includes a first bottom wall 111, a first peripheral wall 112 connected to the first bottom wall 111, and a mating rib 113 disposed on the first bottom wall 111 and surrounded by the first peripheral wall 112. The first peripheral wall 112 includes a long side wall 112a and two oppositely disposed short side walls 112b. The two short side walls 112b are respectively connected to the opposite ends of the long side wall 112a and are orthogonal to the long side wall 112a, thus forming a U-shape. An opening is formed on the side of the first peripheral wall 112 opposite to the long side wall 112a for the insertion and routing of the wire connector 20. Two metal locking tabs 14 are inserted into the recesses on the outer surfaces of the two short side walls 112b.

[0040] The mating rib 113 includes a first section 113a, a second section 113b, and a third section 113c, as shown below. Figure 5 As shown, the first segment 113a and the third segment 113c are located on opposite sides of the second segment 113b. The height of the first segment 113a is greater than the height of the second segment 113b, and the height of the first segment 113a is greater than the height of the third segment 113c. The second segment 113b and the third segment 113c have the same height. The second segment 113b has a plurality of first terminal receiving slots 113d. One first power terminal 12 is disposed in the first segment 113a, another first power terminal 12 is disposed in the third segment 113c, and a first signal terminal 13 is disposed in the first terminal receiving slot 113d of the second segment 113b. Thus, the first signal terminals 13 are disposed at intervals on the second segment 113b of the mating rib 113, and two first power terminals 12 are disposed on the first segment 113a and the third segment 113c of the mating rib 113 and are located on opposite sides of the first signal terminals 13.

[0041] The first insulating structure 11 further includes a base portion 114, and a mating rib 113 is disposed on the base portion 114, such that the bottom of the mating rib 113 and the surface of the first bottom wall 111 have a height difference.

[0042] One of the first power terminals 12 is higher than the other. The higher first power terminal 12 can be used for the negative terminal, and the higher first power terminal 12 can be used for the positive terminal. Figure 5As shown, although in this embodiment the first power terminal 12, which is the negative terminal, is located to the left of the first signal terminal 13, and the first power terminal 12, which is the positive terminal, is located to the right of the first signal terminal 13, this invention is not limited to this. In other embodiments, the first power terminal 12, which is the negative terminal, may also be located to the right of the first signal terminal 13, and the first power terminal 12, which is the positive terminal, may also be located to the left of the first signal terminal 13. When the wire-end electrical connector 20 mates with the board-end electrical connector 10, the second power terminal 22, which is the negative terminal, will first contact the first power terminal 12, which is the negative terminal, and then the second power terminal 22, which is the positive terminal, will contact the second power terminal 22, which is the positive terminal.

[0043] Each first power terminal 12 and / or each first signal terminal 13 includes a first mating portion 10a and a first soldering portion 10b. The first mating portion 10a is U-shaped and engages with and is supported by the mating rib 113. Each first soldering portion 10b is connected to the first mating portion 10a and extends to the outer side of the first peripheral wall 112. The first soldering portion 10b is soldered to a pad P1 of a circuit board P, thereby forming an electrical connection between the board-end electrical connector 1 and the circuit board P. The metal locking tab 14 is connected to the grounding pad of the circuit board P to form a ground. The width of the first power terminal 12 is greater than the width of the first signal terminal 13.

[0044] In this embodiment, the first power terminal 12 and the first signal terminal 13 are bonded to the first insulating structure 11 by an embedded injection molding process, and then the metal locking piece 14 is assembled on the opposite sides of the first insulating structure 11.

[0045] The second insulating structure 21 includes a mating insulating structure 211 and a connecting insulating structure 212. The mating insulating structure 211 includes a second bottom wall 211a, a second peripheral wall 211b disposed on the second bottom wall 211a, a positioning wall 211c disposed on the second bottom wall 211a, and a plurality of second terminal receiving grooves 211d formed on the second peripheral wall 211b and the second bottom wall 211a. The second peripheral wall 211b includes two long side walls 211b1 and two short side walls 211b2, which surround to form a mating groove 211e. The positioning wall 211c has a predetermined distance from the second peripheral wall 211b. The second terminal receiving grooves 211d are formed on the second peripheral wall 211b and the second bottom wall 211a, and the second power terminal 22 and the second signal terminal 23 are disposed in the second terminal receiving grooves 211d.

[0046] The second power terminals 22 are divided into two groups, and the two groups of second power terminals 22 are respectively disposed on opposite sides of the second signal terminals 23. Each second power terminal 22 and / or each second signal terminal 23 is plate-shaped and includes a second mating portion 20a and a second welding portion 20b. The second welding portion 20b is connected to the second mating portion 20a. The second mating portion 20a is circumferentially disposed on the groove wall of the mating groove 211e. The second welding portion 20b extends to the outer side of the second peripheral wall 211b. The second mating portion 20a includes a fixing protrusion 20a1, an elastic cantilever 20a2, and a connecting section 20a3 connecting the fixing protrusion 20a1 and the elastic cantilever 20a2. The fixing protrusion 20a1 and the elastic cantilever 20a2 are disposed opposite to each other. Figure 17 As shown, when the first power terminal 12 is connected to the second power terminal 22 or the first signal terminal 13 is connected to the second signal terminal 23, the first mating portion 10a abuts against the fixed protrusion 20a1 and the elastic cantilever 20a2, and the elastic cantilever 20a2 elastically deforms, causing the first mating portion 20a to be clamped and contacted by the fixed protrusion 20a1 and the elastic cantilever 20a2. Please refer to the following: Figure 15 The distance between two adjacent second power terminals 22 is less than the distance between two adjacent second signal terminals 23, thereby reducing the size of the wire connector 20.

[0047] The connecting insulation structure 212 is molded onto the mating insulation structure 211 using an embedded injection molding process, positioning the second power terminal 22 and the second signal terminal 23 on the second bottom wall 211a and the second peripheral wall 211b of the mating insulation structure 211. The connecting insulation structure 212 has a retaining wall 212a, a plurality of first mating grooves 212b, and a plurality of second mating grooves 212c. The first mating grooves 212b communicate with the portion of the second terminal receiving groove 211d that houses the second power terminal 22 located on the second bottom wall 211a, and the second solder portion 20b of the second power terminal 22 protrudes from the first mating groove 212b. The plurality of second mating grooves 212c communicate with the portion of the second terminal receiving groove 211d that houses the second signal terminal 23 located on the second bottom wall 211a, and the second solder portion 20b of the second signal terminal 23 protrudes from the second mating grooves 212c.

[0048] The retaining wall 212a closes the portion of the second terminal receiving groove 211d located on the second peripheral wall 211b and near the connecting insulating structure 212, thus creating a barrier between the second mating portion 20a of the second power terminal 22 and the second signal terminal 23 located in the mating groove 211e and the portion of the second power terminal 22 and the second signal terminal 23 located in the first mating groove 212b and the second mating groove 212c. This prevents solder from overflowing into the second mating portion 20a of the second power terminal 22 and the second signal terminal 23 when a cable or flexible circuit board is soldered to the second soldering portion 20b of the second power terminal 22 and the second signal terminal 23 located in the mating groove 211e. The surface of the connecting insulating structure 212 at the second mating groove 212c has multiple groove walls 212d, and the surface of the connecting insulating structure 212 at the first mating groove 212b is a flat surface. In this embodiment, the height of the groove wall 212d is higher than the second welding part 20b of the second signal terminal 23 exposed in the second bonding groove 212c. When the cable C is welded to the second welding part 20b of the second signal terminal 23, the groove wall 212d can separate the cable C and prevent solder overflow from causing a short circuit.

[0049] Please see Figures 6 to 10 ,like Figure 6 and Figure 7 As shown, in this embodiment, the second power terminal 22 and the second signal terminal 23 are embedded in the mating groove 211e of the second peripheral wall 211b of the mating insulation structure 211 using an injection molding process. Then, the metal housing 24 is assembled onto the surface of the second bottom wall 211a of the mating insulation structure 211, away from the mating groove 211e. Please refer to [further details omitted]. Figure 11 and Figure 12 The metal housing 24 includes two positioning lugs 241, a protrusion 242, and two engaging lugs 243. The two positioning lugs 241 engage with two recesses 211a1 of the second bottom wall 212a, and the two engaging lugs 243 engage with two protrusions 211a2 of the second bottom wall 211a, thereby positioning the metal housing 24 against the mating insulating structure 211. A gap is formed between the protrusion 242 and the second bottom wall 211a for a pull strap B to pass through. Then as follows... Figure 8 As shown, the connecting insulation structure 212 is molded onto the mating insulation structure 211 using an embedded injection molding process. Simultaneously, the connecting insulation structure 212 covers and is bonded to the mating lug 241, thus fixing the metal shell 24 to the second insulation structure placement structure 21. Figure 9As shown, a power supply metal sheet 25 is respectively provided on two flat surfaces of the connecting insulating structure 212 at the first connecting groove 212b. The power supply metal sheet 25 has multiple slots 251. The second welding portion 20b of the second power terminal 22 passes through the slot 251 and contacts the hole wall of the slot 251, so that the power supply metal sheet 25 connects the multiple second power terminals 22 in parallel in each group, thereby reducing impedance to increase the allowable current value and avoiding heat generation. Figure 10 As shown, multiple cables C are soldered to the second soldering portion 20b of the second power terminal 22 and the second soldering portion 20b of the second signal terminal 23, respectively, so that the wire-end electrical connector 20 forms an electrical connection with the multiple cables C. When the wire-end electrical connector 20 mates with the board-end electrical connector 10, the cables C and the circuit board P are electrically connected via the mating board-end electrical connector 10 and the wire-end electrical connector 20.

[0050] Please see Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 This indicates the mating state of the board-side electrical connector 10 and the wire-side electrical connector 20 in this embodiment. When the wire-side electrical connector 20 mates with the board-side electrical connector 10, the mating groove 211e mates with the mating rib 113, and the two first power terminals 12 respectively mate with the two sets of second power terminals 22, and the first signal terminal 13 correspondingly mates with the second signal terminal 23. The width of each first power terminal 12 perpendicular to the mating direction is greater than the sum of the widths of each group of multiple second power terminals 22 perpendicular to the mating direction.

[0051] The first segment 113a, the second segment 113b, and the third segment 113c of the mating rib 113 of the first insulating structure 11 have predetermined engagement gaps between each other, between the first segment 113a and the first peripheral wall 112, and between the third segment 113c and the first peripheral wall 112. The second insulating structure 21 further includes a plurality of positioning ribs 211f within the mating groove 211e. When the wire-end electrical connector 20 mates with the board-end electrical connector 10, the short sidewall 211b2 of the second peripheral wall 211b and the positioning ribs 211f engage with the aforementioned engagement gaps of the first insulating structure 11. This provides a guiding effect when the wire-end electrical connector 20 mates with the board-end electrical connector 10.

[0052] The first insulating structure 11 further includes two first guide ribs 115 and two second guide ribs 116. The two first guide ribs 115 are disposed on the long side wall 112a, and the two second guide ribs 116 are respectively disposed on the two short side walls 112b. The first guide ribs 115 and the second guide ribs 116 extend from the top of the first peripheral wall 112 to the first bottom wall 111. The second insulating structure 21 includes two first recesses 213 and two second recesses 214. The two first recesses 213 are formed on the side of the positioning wall 211c near the second peripheral wall 211b, and the two second recesses 214 are formed on the side of the second peripheral wall 211b in the direction orthogonal to the positioning wall 211c. When the wire-end electrical connector 20 mates with the board-end electrical connector 10, the two first recesses 213 engage with the two first guide ribs 115, and the two second recesses 214 engage with the two second guide ribs 116. Since the engagement of the first recess 213 with the first guide rib 115 and the engagement of the second recess 214 with the second guide rib 116 are in two perpendicular directions, the engagement structure in both directions can provide a limiting effect, preventing misalignment when the wire-end electrical connector 20 and the board-end electrical connector 10 are connected, and ensuring that the aforementioned second power terminal 22, which is the negative terminal, contacts the first power terminal 12, which is the negative terminal, first.

[0053] The first insulating structure 11 further includes two positioning protrusions 117, which are respectively disposed at the connection between the long side wall 112a and the two short side walls 112b. The second insulating structure 21 further includes two engaging recesses 215, which are formed on the surface of the positioning wall 211c near the second peripheral wall 211b and located at both ends of the positioning wall 211c. Each metal locking piece 14 of the board-end electrical connector 10 has a central opening 141 and an upper recess 142, which is located on the side of the metal locking piece 14 away from the first bottom wall 111. The metal housing 24 of the wire-end electrical connector 20 further includes two engaging springs 244.

[0054] When the wire-end electrical connector 20 and the board-end electrical connector 10 are mated, the two engaging springs 244 are guided by the upper recess 142 and respectively engage with the two central openings 141. At the same time, the two positioning protrusions 117 of the first insulating structure 11 respectively engage with the two engaging recesses 215 of the second insulating structure 21, thereby positioning the wire-end electrical connector 20 on the board-end electrical connector 10. When the wire-end electrical connector 20 and the board-end electrical connector 10 need to be separated, the user applies force to the pull strap B to make the wire-end electrical connector 20 vertically detach from the board-end electrical connector 10.

[0055] like Figure 17As shown, when the wire-end electrical connector 20 and the board-end electrical connector 10 are connected, the second mating part 20a of the second signal terminal 23 clamps and contacts the first mating part 10a of the first signal terminal 13, so that the cable C and the circuit board P form an electrical connection.

[0056] Please see Figure 18 , Figure 19 and Figure 20 This represents another embodiment of the vertical plug-in board connector assembly of this utility model. This embodiment has some of the same structure as the previous embodiment, therefore the same elements are given the same reference numerals and their descriptions are omitted. The difference between this embodiment and the previous embodiment is that the second solder portion 20b of the second power terminal 22 and the second signal terminal 23 in this embodiment is soldered to a flexible circuit board F. The height of the groove wall 211d in this embodiment is lower than the second solder portion 20b of the second signal terminal 23 exposed in the second mating groove 212c, so that the second solder portion 20b of the second signal terminal 23 can contact the flexible circuit board F flush with the second solder portion 20b of the second power terminal 22. The connecting insulation structure 212 of the second insulation structure 21 is further provided with two positioning protrusions 212g on the surface of the second mating groove 212c. The two positioning protrusions 212g are provided at opposite ends of the connecting insulation structure 212 for positioning the flexible circuit board F.

[0057] The vertical plug-in wire-to-board electrical connector assembly of this utility model simplifies the manufacturing process by combining the first power terminal and the first signal terminal of the board-end connector with the first insulation structure through an embedded injection molding process. Furthermore, the width of the first power terminal is greater than the sum of the widths of each group of second power terminals, which increases the transmitted current and reduces contact heat generation. The second power terminal and the second signal terminal of the wire-end connector both use sheet-like terminals, which reduces the terminal spacing and thus the size of the wire-end connector, facilitating miniaturization. The spacing between adjacent second signal terminals is greater than the spacing between adjacent second power terminals, making it easier to solder the cable core wires to the wire-end connector. Moreover, the wire-end connector is soldered to the cable only after the entire assembly is completed, increasing the convenience of cooperation with manufacturing manufacturers and significantly reducing processing costs.

[0058] The above description is merely a preferred embodiment of this utility model and should not be construed as limiting the scope of this utility model. Any simple equivalent changes and modifications made based on the claims and description of this utility model are still within its scope. Furthermore, no embodiment or claim of this utility model needs to achieve all the objectives, advantages, or features provided by this utility model. In addition, the abstract and headings are only for assisting in patent document searches and are not intended to limit the scope of protection of this utility model. Furthermore, the terms "first," "second," etc., mentioned in this specification or claims are only used to name elements or distinguish different embodiments or scopes, and are not used to limit the upper or lower limit of the number of elements.
