[0034] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0035] Example 1:
[0036] like Figure 1-17As shown, the Type-C electrical connector female socket of this embodiment includes an insulating body 1 and terminals, with the terminals disposed on the insulating body 1. The Type-C electrical connector female socket also has a metal housing 9. The terminals include several terminals in the upper row and several terminals in the lower row. Specifically, in this embodiment, the terminals in the upper row include a ground terminal 31, a positive power terminal 32, a detection terminal 33, a positive power terminal 35, and a ground terminal 36; the terminals in the lower row include a ground terminal 21, a positive power terminal 22, a detection terminal 23, a detection terminal 25, a positive power terminal 26, and a ground terminal 27. In this embodiment, reinforcing blocks 29 and 39 are also provided, which can improve the overall strength of the insulating body 1. The reinforcing blocks 29 and 39 are made of the same material as each terminal. At least some terminals overlap with terminals of the same type in different rows. Specifically, in this embodiment, grounding terminal 31 is connected to grounding terminal 21, power positive terminal 32 is connected to power positive terminal 22, detection terminal 33 is connected to detection terminal 23 (detection terminal 23 has no mating part), power positive terminal 35 is connected to power positive terminal 26, and grounding terminal 36 is connected to grounding terminal 27. Grounding terminal 31, power positive terminal 32, detection terminal 33, power positive terminal 35, and grounding terminal 36 do not have solder pads; they share solder pads with the terminals they are connected to through connection. This reduces the number of solder pads, facilitates maintenance, reduces the PCB area occupied by the Type-C female connector, and simplifies board layout.
[0037] The terminals that overlap with the same type of terminal include a fixing part, a mating part connected to the fixing part, and a front overlapping spring arm connected to the fixing part, the front overlapping spring arm overlapping the terminal being overlapped. Specifically, the grounding terminal 31 includes a fixing part 311, a mating part 312 connected to the fixing part 311, and a front overlapping spring arm 319 connected to the fixing part 311, the front overlapping spring arm 319 overlapping the grounding terminal 21. The power positive terminal 32 includes a fixing part 321, a mating part 322 connected to the fixing part 321, and a front overlapping spring arm 329 connected to the fixing part 321, the front overlapping spring arm 329 overlapping the power positive terminal 22. The detection terminal 33 includes a fixing part 331, a mating part 332 connected to the fixing part 331, and a front overlapping spring arm 339 connected to the fixing part 331, the front overlapping spring arm 339 overlapping the detection terminal 23. The positive power terminal 35 includes a fixing part 351, a mating part 352 connected to the fixing part 351, and a front lap spring arm 359 connected to the fixing part 351. The front lap spring arm 359 overlaps with the positive power terminal 26. The ground terminal 36 includes a fixing part 361, a mating part 362 connected to the fixing part 361, and a front lap spring arm 369 connected to the fixing part 361. The front lap spring arm 369 overlaps with the ground terminal 27. At least some of the front lap spring arms of the terminals are located on adjacent sides of the front lap spring arms of their adjacent terminals. Specifically, the front lap spring arm 369 of the ground terminal 36 and the front lap spring arm 359 of the positive power terminal 35 are located on adjacent sides of the two terminals; the front lap spring arm 339 of the detection terminal 33 and the front lap spring arm 329 of the positive power terminal 32 are located on adjacent sides of the two terminals.
[0038] The terminals that are connected to the same type of terminal include a rear connection spring arm, which connects to the terminal being connected. Specifically, grounding terminal 31 includes a rear connection spring arm 318, which connects to grounding terminal 21. Power positive terminal 32 includes a rear connection spring arm 328, which connects to power positive terminal 22. Detection terminal 33 includes a rear connection spring arm 338, which connects to detection terminal 23. Power positive terminal 35 includes a rear connection spring arm 358, which connects to power positive terminal 26. Grounding terminal 36 includes a rear connection spring arm 368, which connects to grounding terminal 27. By providing a rear connection spring arm, the electrical connection between the two terminals can be enhanced, and it can also provide electrical connection when the front connection spring arm fails. The rear lap arm of the terminal that overlaps with the same type of terminal is formed by bending from the fixing part of the terminal. The rear lap arm is bent toward the terminal it overlaps with.
[0039] The terminals to be overlapped include a fixing portion and a solder foot. The width of the fixing portion of the terminal to be overlapped is at least partially greater than the width of its solder foot, facilitating overlap. Specifically, grounding terminal 21 includes a fixing portion 211, a mating portion 212, and a solder foot 213. Power positive terminal 22 includes a fixing portion 221, a mating portion 222, and a solder foot 223. Detection terminal 23 includes a fixing portion 231 and a solder foot 233. Detection terminal 25 includes a fixing portion 251, a mating portion 252, and a solder foot 253. Power positive terminal 26 includes a fixing portion 261, a mating portion 262, and a solder foot 263. Grounding terminal 27 includes a fixing portion 271, a mating portion 272, and a solder foot 273.
[0040] The outermost terminal, which overlaps with a terminal of the same type, also includes a protrusion connected to its fixing portion. Specifically, grounding terminal 31 has a protrusion 317, and grounding terminal 36 has a protrusion 367. By providing the protrusion, the connection between the terminal and the insulating body 1 can be made more secure and stable.
[0041] The insulating body 1 includes a first insulating block 12 and a second insulating block 11, which are joined together by plastic blocks formed through a secondary molding process. A positioning structure is provided between the first insulating block 12 and the second insulating block 11. Specifically, the first insulating block 12 has a tongue 121 and a fixing seat 122, and the fixing seat 122 has a positioning hole 1221 and a positioning post 1222. The second insulating block 11 has a tongue 111 and a fixing seat 112, and the fixing seat 112 has a positioning hole 1122 that mates with the positioning post 1222 and a positioning post 1121 that mates with the positioning hole 1221. This positioning structure facilitates the assembly of the first insulating block 12 and the second insulating block 11. The terminals located in the upper row are disposed on the first insulating block 12, and the terminals located in the lower row are disposed on the second insulating block 11. The terminals in the upper row are terminals that overlap with terminals of the same type. The first insulating block 12 has several grooves 1223, and each of the front overlapping spring arms is disposed in one of the grooves 1223. Specifically, front overlapping spring arms 319, 329, 339, 359, and 369 are all disposed in their respective grooves 1223. In this way, these front overlapping spring arms are in a free state and have elasticity. When the first insulating block 12 and the second insulating block 11 are engaged, the front overlapping spring arms maintain elastic contact with the terminals being overlapped, thereby making the electrical connection more stable. The rear overlapping spring arms are exposed outside the first insulating block 12. The Type-C connector female also includes a raised section 8 made of plastic. A portion of the fixing part of each terminal in the lower row is embedded in the second insulating block 11, a portion is embedded within the raised section 8, and a middle section is exposed, serving as the exposed fixing part section. The rear contact spring arm is in a free state and elastic, maintaining elastic contact with the exposed fixing part section of the connected terminal, thus making the electrical connection more stable. Specifically, the grounding terminal 21 includes an exposed fixing part section 2119, and the rear contact spring arm 318 contacts the exposed fixing part section 2119. The positive power terminal 22 includes an exposed fixing part section 2219, and the rear contact spring arm 328 contacts the exposed fixing part section 2219. The detection terminal 23 includes an exposed fixing part section 2319, and the rear contact spring arm 338 contacts the exposed fixing part section 2319. The detection terminal 25 includes an exposed fixing part section 2519. The positive power terminal 26 includes an exposed fixed section 2619, with a rear connecting spring arm 358 overlapping the exposed fixed section 2619. The grounding terminal 27 includes an exposed fixed section 2719, with a rear connecting spring arm 368 overlapping the exposed fixed section 2719. The outer side of the rear connecting spring arm overlaps the inner side of the exposed fixed section. For example, the outer side 3181 of the rear connecting spring arm 318 overlaps the inner side 21191 of the exposed fixed section 2119. When the raising section 8 is... Figure 8 The state changes shown are as follows Figure 11In the state of being connected, the outer side 3181 of the rear-connecting spring arm 318 overlaps the inner side 21191 of the exposed section 2119 of the fixing part.
[0042] The two outermost terminals in one row are also provided with retaining parts, which are connected to the mating parts of the terminals. The retaining parts have several through holes. By providing retaining parts, it is unnecessary to provide separate locking mechanisms, improving product integration and facilitating processing; by providing through holes, during injection molding, the adhesive will be poured into the through holes, thus making the connection between the retaining parts and the insulating body 1 more secure. Specifically, the grounding terminal 21 in the lower row is provided with a retaining part 219, which has through holes 2191 and 2192. The grounding terminal 27 in the lower row is provided with a retaining part 279, which has through holes 2791 and 2792.
[0043] like Figure 14-15 As shown, in order to achieve a more stable connection between the insulating body 1 and the raising part 8, a snap-fit structure is provided between the two. Specifically, the raising part 8 is provided with a first barb 89, and the insulating body 1 is provided with a second barb 119 that cooperates with the first barb 89.
[0044] like Figure 1-2 As shown in Figures 16-17, the metal outer shell 9 covers the insulating body 1 and the heightening part 8, providing overall reinforcement and fixing the insulating body 1 and the heightening part 8. Specifically, the metal outer shell 9 includes a rear protective plate 91, a top plate 92, a side plate 93, and a front protective plate 95 connected to each other, as well as fixing feet 99 extending from the side plates. The front protective plate 95 has a through hole 98 for the insulating body 1 to pass through. Lugs 911 are formed on both sides of the rear protective plate 91, and buckles 9111 are formed on the lugs 911. The side plate 93 has through holes (not shown in the figure) that cooperate with the buckles 9111. The buckles 9111 are inserted into the through holes to achieve the engagement of the two. The front protective plate 95 has a support part 951, which can support the insulating body 1.
[0045] Example 2:
[0046] The difference between this embodiment and Embodiment 1 is that the Type-C connector female socket in this embodiment further includes a grounding piece 7. The surface of the grounding piece 7 is exposed, and the grounding piece 7 is riveted together with the grounding terminals 9821 and 9827 located on both sides of the lower row, thereby enabling the two grounding terminals to conduct to each other. Specifically, the grounding piece 7 has a notch 71 in the middle and lugs 72 on both sides, with through holes 721 on the lugs 72. The grounding terminal 9821 has a protrusion 98219 extending into the through hole 721 and a protrusion 98218 extending into the notch 71; the grounding terminal 9827 has a protrusion 98279 extending into the through hole 721 and a protrusion 98278 extending into the notch 71; thus, a riveting connection is achieved. Of course, the Type-C connector female socket in this embodiment also includes a grounding piece riveted to the grounding terminals located on both sides of the upper row, the structure of which and the riveting structure are the same as those of the grounding piece 7, and will not be described in detail here. By setting a grounding plate and riveting it to a grounding terminal, static charge on the male connector connected to the Type-C electrical connector female can be conducted away.
