The connector module 1 includes the board connector 2 which can be welded on a circuit board (not shown in figures), and the cable connector 3 for assembling with the board connector 2.
The board connector 2 includes a board connecting body 21, a plurality of conductive terminals 22, and a pair of metal pads 23. A slot 210 is formed on the board connecting body 21, and a plurality of terminal grooves 211 is also formed on the board connecting body 21 and communicated with the slot 210. Two inserting slots 212 are formed on two sides of the board connecting body 21, respectively. The plurality of conductive terminals 22 is disposed on the board connecting body 21 and extends into the slot 210. Specifically, the plurality of conductive terminals 22 is installed inside the plurality of terminal grooves 221, and a contacting portion 221 of each conductive terminal 22 extends into the slot 210. The two metal pads 23 are assembled inside the two inserting slots 212 formed on the two sides of the board connecting body 21, respectively. Each metal pad 23 includes a resilient buckle 231 protruding out of the board connecting body 21.
The cable connector 3 includes a cable connecting body 31 and a flexible transmission unit 32. The cable connecting body 31 includes an installation portion 311 and two engaging portions 312 disposed on two sides of the installation portion 311 of the cable connecting body 31. The flexible transmission unit 32 is installed in the installation portion 311 of the cable connecting body 31, so as to fix the flexible transmission unit 32 on the cable connecting body 31. In this embodiment, the flexible transmission unit 32 can be a flexible flat cable, and a plurality of contacts 321 is disposed on a front end of the flexible transmission unit 32. The installation portion 311 of the cable connecting body 31 can be a slit structure wherethrough the flexible transmission unit 32 is inserted and fastened, and a positioning portion 313 is disposed in the slit structure. Two interfering portions 322 are disposed on two sides of the flexible transmission unit 32 respectively and for interfering with the positioning portion 313, so as to fix the flexible transmission unit 32 in the cable connecting body 31. Furthermore, a groove 316 is formed inside the cable connecting body 31 and communicated with the installation portion 311, i.e. the slit structure, and the plurality of contacts 321 disposed on the front end of the flexible transmission unit 32 is located in the groove 316, so that the cable connecting body 31 can surround the plurality of contacts 321 for preventing the plurality of contacts 321 from being hit by external objects. That is, when the cable connector 3 is connected with the board connector 2, the board connecting body 21 of the board connector 2 is inserted into the groove 316 of the cable connector 3, so that the cable connecting body 31 can surround or cover the board connecting body 21 and the resilient buckle 231.
When the cable connector 3 is connected with the board connector 2, the front end of the flexible transmission unit 32 is inserted into the slot 210 and the plurality of conductive terminals 22 contacts with the plurality of contacts 321. At this time, the resilient buckle 231 of the metal pad 23 engages with the corresponding engaging portion 312 of the cable connecting body 31. In this embodiment, the resilient buckle 231 can be a hook-shaped spring protruding from the board connecting body 21, the engaging portion 312 can be a sunken portion disposed on the cable connecting body 31. The sunken portion is disposed in the groove 316 and corresponding to the hook-shaped spring, and the hook-shaped spring engages inside the sunken portion when the cable connector 3 is connected with the board connector 2, so as to fasten the cable connector 3 with the board connector 2.
In this embodiment, at least one inclined plane 213 is formed on an outer surface of the board connecting body 21 so that the board connecting body 21 is formed in an asymmetric shape. Similarly, another inclined plane 314 is formed on an outer surface of the cable connecting body 31 and corresponding to the inclined plane 213 on the outer surface of the board connecting body 21, so as to achieve fool-proofing function and prevent occurrence of incorrect insertion. Besides, at least one sunken plane 214 is formed on an outer surface of the board connecting body 21 so that the board connecting body 21 is formed in an asymmetric shape. Similarly, a protrusion 315 is disposed in the groove 316 formed inside the cable connecting body 31 and corresponding to the sunken plane 214, and the sunken plane 214 and the protrusion 315 engage with each other when the board connecting body 21 of the board connector 2 is inserted into the groove 316 of the cable connector 3 so that the cable connector 3 is connected with the board connector 2, so as to achieve the fool-proofing function.
Besides, the slot 210 is formed on a top of the board connecting body 21, at least one symbol 215 is marked on the top of the board connecting body 21 and located in a position adjacent to the slot 210, and another symbol 317 is marked on the cable connecting body 31 and corresponding to the symbol 215, for achieving the fool-proofing function by another way. The symbols 215, 317 can be formed in a triangular shape. When it is desired to connect the cable connector 3 with the board connector 2, the symbol 317 marked on the cable connecting body 31 needs to be aimed at the symbol 215 marked on the top of the board connecting body 21 for correct insertion, so as to achieve the fool-proofing function and prevent occurrence of incorrect insertion.
