Before the present invention is described in detail, it should be noted that in the following description, like elements are denoted by the same reference numerals.

Referring to fig. 1 and 2, a first embodiment of a receptacle connector 100 according to the present invention includes an insulative housing 1, a plurality of pairs of terminal modules 2, and a metal shell 3. The socket connector 100 is adapted to be assembled and electrically connected to a circuit board 5, and the circuit board 5 is formed with a plurality of through holes 51.

For convenience of description, a front-rear direction X, a left-right direction Y perpendicular to the front-rear direction X, and an up-down direction Z perpendicular to the front-rear direction X and the left-right direction Y of the receptacle connector 100 are defined. The front-rear direction X in fig. 1 is the direction indicated by the arrow, and the reverse direction is the rear direction. The left-right direction Y in fig. 1 is the direction indicated by the arrow and the reverse direction is the right. The up-down direction Z in fig. 1 is the direction indicated by the arrow, and the reverse direction is the downward direction.

Referring to fig. 3, 4 and 5, the insulating body 1 has a long shell shape and extends in the left-right direction Y in the long direction. The insulating body 1 has two outer sections 11 disposed opposite to each other in the left-right direction Y, and a recessed section 12 located between the outer sections 11. The plurality of outer sections 11 and the recessed section 12 are arranged in the left-right direction Y. Each of the outer sections 11 is formed with a slot 111. The slot 111 extends in the left-right direction Y and has a length L1 taken in the left-right direction Y. The recessed section 12 is connected to the plurality of outer sections 11 and is located between the plurality of slots 111.

The number of the plurality of terminal modules 2 is two. Each of the terminal modules 2 has a terminal block 21, and a plurality of terminals 22 disposed on the terminal block 21 and arranged at intervals along the left-right direction Y. The terminal blocks 21 of each pair of the terminal modules 2 are fixedly coupled together by, for example, snap-fit, and mounted to the corresponding outer sections 11 of the insulative housing 1. Each of the terminals 22 is electrically connected to the circuit board 5 and has a contact portion 221 extending into the corresponding slot 111.

The metal shell 3 is sleeved on the insulating body 1 and surrounds the outer periphery of the insulating body 1. Two front grooves 41 respectively located at the front sides of the plurality of slots 111 and two rear grooves 42 respectively located at the rear sides of the plurality of slots 111 are formed between the metal housing 3 and the insulating body 1. Each of the front grooves 41, the corresponding slot 111, and the corresponding rear groove 42 are aligned along the front-rear direction X. The longitudinal direction of each of the front grooves 41 extends in the left-right direction Y. The length of each rear slot 42 extends along the left-right direction Y and has a length L2 taken along the left-right direction Y, and the length L2 of the rear slot 42 is smaller than the length L1 of the slot 111.

By the design of the slots 111, the recessed sections 12, the front slots 41 and the rear slots 42, the receptacle connector 100 can mate not only with two plug connectors (not shown) but also with one electronic card 6 (as shown in fig. 7). Thus, the socket connector 100 can provide at least two different types of mating parts (such as the plug connector and the electronic card 6), so that the socket connector 100 can be widely applied and can meet the use requirements for the mating of the different types of mating parts.

The specific structure of the receptacle connector 100 will be described in detail below:

referring to fig. 3, 4 and 5, each of the slots 111 has an upward opening 112. The recessed section 12 has a bottom wall 121 and two sides 122 connected to the bottom wall 121. A plurality of side surfaces 122 protrude from the top surface of the bottom wall 121 and are spaced apart and facing each other in the left-right direction Y. The plurality of side surfaces 122 are located inside the plurality of slots 111, respectively. The bottom wall 121 and the sides 122 together define a recess 123, and the recess 123 has an opening 124 facing upward. The bottom wall 121 of the recess 12 is formed with two through holes 125 adjacent to the side surfaces 122, respectively, and each through hole 125 extends along the up-down direction Z and penetrates the bottom wall 121.

In the first embodiment, two protruding blocks 13 are respectively extended rearward from the rear side of the insulating body 1 at positions corresponding to two ends of each slot 111. Each of the rear grooves 42 is formed between the corresponding two of the bumps 13. Specifically, each of the outer sections 11 of the insulating body 1 has a front side 113 located at the front side of the corresponding slot 111, a rear side 114 located at the rear side of the corresponding slot 111, and an outer end 115 located outside the corresponding slot 111 and opposite to the corresponding side 122. The insulating body 1 has four protruding blocks 13, and each two protruding blocks 13 extend backward from the corresponding back side 114 and respectively correspond to two ends of the corresponding slot 111. The two outermost bumps 13 correspond to the outer ends 115, respectively, and the other two middle bumps 13 correspond to the side surfaces 122, respectively.

Referring to fig. 3, 5 and 6, the insulating body 1 further has a connecting block 14 and a holding block 15. The connection block 14 is connected between corresponding two bumps 13 adjacent to the recessed section 12, the connection block 14 being adjacent to the ends of the bumps 13 and being flush with the bumps 13. The connection blocks 14 and the corresponding plurality of bumps 13 are connected between the plurality of outer sections 11, so that the overall structural strength of the insulating body 1 can be increased. The holding block 15 is protruded on the rear wall surface of the bottom wall 121, the rear side surface of the connecting block 14, and the rear side surfaces of the corresponding plurality of bumps 13. The holding block 15 is formed with a holding groove 151, and the holding groove 151 extends along the up-down direction Z and has an opening facing upwards.

Referring to fig. 3, 4, 5 and 6, the metal case 3 has a long case shape and extends in the left-right direction Y in the long direction. The metal shell 3 has two front plates 31, a rear plate 32, two side plates 33, and two flaps 34. The front plates 31 are spaced apart in the left-right direction Y and are respectively located in front of the front side surfaces 113 of the outer side segments 11. Each front plate 31 has a pin 311 at the bottom end and extending downward, and the pin 311 is configured to be inserted into the corresponding through hole 51 of the circuit board 5, so that the pin 311 and the circuit board 5 can be fixedly combined together by solder. The rear plate 32 is located behind the plurality of front plates 31 at intervals in the front-rear direction X. The back plate 32 has a first plate 320 and a second plate 321. The first plate 320 is located behind the rear sides 114, behind the bumps 13, and behind the connection block 14. The first plate 320 has a holding piece 322 located in the middle of the bottom end and extending downward, and the holding piece 322 is snapped into the holding groove 151 of the insulating body 1. Thus, the stability and flatness of the metal shell 3 when assembled on the insulating body 1 can be improved. The second plate body 321 extends downward and backward from the bottom end of the first plate body 320, the second plate body 321 has a plurality of pins 323 located at the bottom end and extending downward, each pin 323 is configured to be inserted into the corresponding through hole 51 of the circuit board 5, so that the pins 323 and the circuit board 5 can be fixedly combined together by solder.

The side plates 33 are respectively connected to the left and right sides of the first plate body 320 of the rear plate 32 and are respectively connected to the outer sides of the front plates 31. Flaps 34 are respectively connected to the inner sides of the front panels 31 and respectively extend rearwardly to the inner sides of the sides 122 of the recessed section 12. Each of the flaps 34 has a plate 341 and a pin 342 extending downwardly from a bottom end of the plate 341. The plate 341 is located inside the corresponding side 122 and abuts against the top surface of the bottom wall 121. The bottom wall 121 can simultaneously support a plurality of folded plates 34, so that the stability and the flatness of the metal shell 3 when assembled on the insulating body 1 can be further improved. The pins 342 are inserted into the corresponding through holes 125 and partially protrude below the corresponding through holes 125, and are inserted into the corresponding through holes 51 of the circuit board 5, so that the pins 342 and the circuit board 5 can be fixedly combined together by solder. The pins 342 are inserted through the through holes 125 to locate the pins 342, so that the positional accuracy of the pins 342 when soldered to the circuit board 5 is improved.

The inner surface of each front plate 31 of the metal casing 3, the inner surface of the corresponding side plate 33, and the inner surface of the plate body 341 of the corresponding folded plate 34 cooperate with the corresponding front side 113 of the insulating body 1 to define the corresponding front slot 41, and the front slot 41 has an upward opening 411. The inner plate surface of the first plate 320 of the metal shell 3 and the corresponding rear side surface 114 of the insulating body 1 and the corresponding two bumps 13 together define the corresponding rear slot 42, and the rear slot 42 has an upward opening 421.

Referring to fig. 5 and 6, the receptacle connector 100 can provide two similar types of mating of the plug connector. One type of such plug connector mainly includes a circuit board, and a front plate and two side plates surrounding the circuit board. Another type of the plug connector mainly comprises a circuit board, and a front board, a rear board and two side boards surrounding the circuit board. The slot 111, the front slot 41, the rear slot 42 and the recess 123 of the recess 12 of the socket connector 100 are respectively used for plugging the circuit board, the front board, the rear board and the corresponding side boards. The circuit board of the plug connector can be plugged into the slot 111 through the opening 112 or removed from the slot 111. The front plate of the plug connector can be inserted into the front slot 41 or removed from the front slot 41 through the opening 411. The rear plate of the plug connector can be inserted into the rear slot 42 or removed from the rear slot 42 through the opening 421. The corresponding side plate of the plug connector can be inserted into the groove 123 or removed from the groove 123 through the opening 124.

Referring to fig. 7 and 8, the receptacle connector 100 can also provide two similar types of mating of the electronic card 6. One type of the electronic card 6 mainly includes two insertion portions 61, and a guide portion 62 located between the insertion portions 61. Another type of electronic card (not shown) has only a plurality of plug-in portions 61 and no guide portion 62. The slots 111 of the socket connector 100 and the grooves 123 of the recessed section 12 are respectively used for plugging the plugging portions 61 and the guiding portions 62. Each of the plugging portions 61 of the electronic card 6 can be plugged into the corresponding slot 111 or removed from the corresponding slot 111 through the corresponding opening 112. The guiding portion 62 of the electronic card 6 can be inserted into the groove 123 or removed from the groove 123 through the opening 124.

As can be seen from the foregoing description, the socket connector 100 of the first embodiment can further provide two similar types of mating of the plug connector and two similar types of mating of the electronic card 6 in addition to the two different types of mating of the plug connector and the electronic card 6. Thus, the socket connector 100 can be widely applied and has elasticity.

It should be noted that, in another implementation of the first embodiment, the socket connector 100 may omit the rear slots 42 as required, so that the plug connector that the socket connector 100 can mate with is a plug connector without the rear plate.

Referring to fig. 9, the second embodiment of the socket connector 100 of the present invention has the same overall structure as the first embodiment, except for the structure of the insulating body 1 and the metal shell 3.

Referring to fig. 9, 10 and 12, the rear side of the metal housing 3 is close to the insulating body 1 at the positions corresponding to the two ends of each slot 111. The rear side of the metal shell 3 corresponding to the middle portion of each of the slots 111 protrudes rearward away from the insulating body 1 and defines the corresponding rear slot 42 together with the insulating body 1. Specifically, the first plate 320 of the metal shell 3 has a base 324, two sides 325, and two protrusions 326. The base 324 corresponds to the recessed section 12 and is proximate to the rear sides 114 of the outboard sections 11. The side portions 325 extend inward from rear ends of the side plates 33, respectively, and the side portions 325 correspond to the outer end portions 115 of the outer side segments 11 and are adjacent to the rear side surfaces 114, respectively. Each of the side portions 325 and the base portion 324 corresponds to two ends of the corresponding slot 111. Each of the protrusions 326 is connected between the base 324 and the corresponding side 325 and has two side panels 327 and a connecting piece 328. A plurality of side panels 327 extend rearwardly from the outside of the base 324 and the inside of the corresponding side portion 325, respectively. The connecting tab 328 is connected to the rear ends of the plurality of side panels 327 and is remote from the corresponding rear side 114. Each of the protruding portions 326 corresponds to a central portion of the corresponding slot 111 and defines the corresponding rear slot 42 with the corresponding rear side 114.

Referring to fig. 10, 11 and 13, the holding block 15 of the insulating body 1 is connected to the rear end of the bottom wall 121 of the recessed section 12 and the rear sides 114 of the outer sections 11. The holding block 15 is further formed with a through hole 152 extending downward from the bottom end of the holding groove 151. The holding groove 151 and the through hole 152 penetrate the holding block 15 along the up-down direction Z. The length of the through hole 152 along the left-right direction Y is smaller than the length of the holding groove 151 along the left-right direction Y. The retaining piece 322 of the first plate 320 extends downward from the bottom end of the base 324 and is engaged with the retaining groove 151. The first board 320 further has a pin 329 extending downward from the bottom end of the holding piece 322, where the pin 329 penetrates the through hole 152 and protrudes partially below the through hole 152 to be inserted into a through hole (not shown) of the circuit board 5 (shown in fig. 1), so that the pin 329 and the circuit board 5 can be fixedly combined together by solder.
