Description

Technical Field

[0001] This invention relates to a wire-end connector, and more particularly to a wire-end connector, a board-end connector, and combinations thereof. Background Technology

[0002] Chinese Invention Patent Publication No. CN103872484B discloses an electrical connector assembly in which a first contact portion of a long terminal and a first contact portion of a short terminal are inserted into an elastic cylindrical member housed in a corresponding first receiving terminal of a first mounting connector. Upon further insertion, the first contact portions of the long and short terminals respectively cause the annular constriction neck of the corresponding elastic cylindrical member to elastically expand in diameter while descending to a predetermined position. After elastic expansion, each elastic cylindrical member elastically contacts the outer peripheral surface of the first contact portion, and the elastic contact pressure relative to the inner peripheral surface of the receiving hole of the first receiving terminal increases. Then, an intermediate connector is fixed to a first circuit board using screws. When it is desired to remove the intermediate connector from the first circuit board, the intermediate connector is lifted upwards after removing the screws. The terminals are arranged laterally, and the lateral width of the connector designed based on this arrangement is limited by the sum of the widths of the two contact portions, making it difficult to reduce its size.

In detail, the third mating part 222 and the fourth mating part 232 are cylindrical and are respectively used to insert into the two through slots 117b of the housing 11 of the wire connector 1 from the mating surface 111, so as to electrically connect with the elastic contact piece 121f of the cage-shaped contact body 121d of the first mating part 121 and the elastic contact piece 131f of the cage-shaped contact body 131d of the second mating part 131.

[0162] The base 24 is rectangular and is disposed on the rectangular area 211 of the circuit board 21. The base 24 has two through holes 241 formed vertically through the circuit board 21 at the first corner 211a and the second corner 211b, respectively. The third mating portion 222 and the fourth mating portion 232 extend upwards outwards from the two through holes 241. Specifically, the base 24 and the circuit board 21 are secured together by two locking screws 26. (See attached reference) Figure 6 and Figure 10In this embodiment, the third connecting part 221 and the fourth connecting part 231 are a solder foot, which passes through and is soldered to the solder hole 210 of the circuit board 21. The third contact 22 and the fourth contact 23 respectively have a stop part 225 and a stop part 235 for stopping against the top surface of the base 24. Additionally, it should be noted that in this first embodiment, the third contact 22 also has a plurality of interference ribs 223 adjacent to the third connecting portion 221 and used to interfere with the inner wall surface of the corresponding through hole 241, and a plurality of raising protrusions 224 adjacent to the third connecting portion 221 and used to stop against the top surface of the circuit board 21 to raise the space for solder filling; the fourth contact 23 also has a plurality of interference ribs 233 adjacent to the fourth connecting portion 231 and used to interfere with the inner wall surface of the corresponding through hole 241, and a plurality of raising protrusions 234 adjacent to the fourth connecting portion 231 and used to stop against the top surface of the circuit board 21 to raise the space for solder filling. It should be noted that the function of the raising protrusions 224 and 234 is to raise the space for solder filling to increase the soldering strength. In other embodiments, the raising protrusions 224 and 234 may also be omitted.

[0163] See Figure 2 , Figures 4 to 6 and Figure 11 The second locking structure 25 is located at the third corner 211c and extends upwards. In this first embodiment, it is integrally formed from the base 24. The second locking structure 25 is used to lock with the first locking structure 15. The first locking structure 15 has a downwardly extending cantilever 151 and a first fastening unit 152 disposed at the bottom of the cantilever 151. The second locking structure 25 includes a base 251 extending upwards from the base 24 and a second fastening unit 252 disposed at the top of the base 251 for fastening with the first fastening unit 152. The first fastening unit 152 can be, for example, a recess, and the second fastening unit 252 can be, for example, a protrusion that engages with the recess, but the reverse is also possible, and it is not limited to this first embodiment.

[0164] As a whole, the wire connector 1 and the board connector 2, by using the obliquely arranged first contact 12 and second contact 13, and the obliquely arranged third contact 22 and fourth contact 23, can reduce the width of the wire connector 1 and the board connector 2 in the lateral direction (the front-to-back direction D2 and the left-to-right direction D3). In addition, it can also reserve design space for the first locking structure 15 and the second locking structure 25, thereby effectively utilizing the space of the wire connector 1 and the board connector 2. At the same time, it can also make the size of the first locking structure 15 and the second locking structure 25 larger to increase their structural strength.

[0165] See Figure 12 The second embodiment of the combination of the wire-end connector 1 and the board-end connector 2 of the present invention differs from the first embodiment in that the base 251 of the second locking structure 25 is directly disposed at the third corner 211c of the circuit board 21. The base 251 of the second locking structure 25 is disposed on the circuit board 21, for example, but not limited to, by an assembly method. In this second embodiment, the interference ribs 223 and 233 of the third contact member 22 and the fourth contact member 23 that cooperate with the base 24 are eliminated, and the lifting protrusions 224 and 234 are respectively formed at the bottom of the stop portion 225 and the stop portion 235. Furthermore, it should be noted that in a variation of this second embodiment, the lifting protrusions 224 and 234 can be eliminated, in which case the stop portion 225 and the stop portion 235 stop on the top surface of the circuit board 21.

[0166] See Figure 13 and Figure 14 The third embodiment of the combination of the wire-end connector 1 and the board-end connector 2 of the present invention differs from the second embodiment in that the housing 11 is integrally formed by over-molding. The second locking structure 25 includes a base 251 inserted into the circuit board 21 and extending upward, and a screw hole 253 provided on the top of the base 251. The first locking structure 15 has a through opening 153 extending vertically. The opening 153 and the screw hole 253 are used to be locked and fixed by a screw 154 (not shown) so that the first locking structure 15 and the second locking structure 25 are locked together.

[0167] See Figure 15 The fourth embodiment of the combination of the wire-end connector 1 and the board-end connector 2 of the present invention differs from the third embodiment in that the first locking structure 15 further has a screw 154 that is rotatably inserted through the opening 153 and used to screw into the screw hole 253. This prevents the screw 154 from being lost and increases the convenience of the lock.

[0168] See Figure 16 and Figure 17 The fifth embodiment of the combination of the wire-end connector 1 and the board-end connector 2 of the present invention differs from the first embodiment in that the two wires 14 extend from the two wire holes 118b on the upper end face 112 of the cover 118 of the housing 11 into the two through slots 117b of the housing 11, and are electrically connected to the first connecting part 122 and the second connecting part 132, respectively.

[0169] See Figures 18 to 20The sixth embodiment of the combination of the wire-end connector 1 and the board-end connector 2 of the present invention differs from the first embodiment in that the height of the base 24 and its through hole 241, the third contact 22 and the fourth contact 23 in the vertical direction D1 is higher.

[0170] See Figures 21 to 24 The seventh embodiment of the combination of the wire-end connector 1 and the board-end connector 2 of the present invention differs from the first embodiment in that the wire-end connector 1 further has a stop rib 16 disposed within the recess 119 of the housing 11 and located behind the cantilever 151 of the first locking structure 15. This stop rib 16 can be moved backward by the lower section of the cantilever 151 of the first locking structure 15 when (see...) Figure 23 The lower section of the cantilever 151 of the first locking structure 15 is abutted to prevent the first locking structure 15 from being damaged due to excessive deformation. The second locking structure 25 of the board end connector 2 also includes a relief groove 254 formed in the base 251 and corresponding to the abutment rib 16. The relief groove 254 is used to avoid the abutment rib 16 when the first locking structure 15 and the second locking structure 25 are locked together.

[0171] In summary, the present invention, by arranging the first contact 12 and the second contact 13 obliquely and triangularly with the first locking structure 15, and the third contact 22 and the fourth contact 23 obliquely, can reduce the lateral width of the wire connector 1 and the board connector 2. Furthermore, it can reserve design space for the first locking structure 15 and the second locking structure 25, thereby effectively utilizing the space of the wire connector 1 and the board connector 2. At the same time, it allows the first locking structure 15 and the second locking structure 25 to adopt a larger design to increase their structural strength.

[0172] However, the above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the present invention.
