Viewed from the width direction WW of the circuit board 200, the first conductive holes 201 and the second conductive holes 203 are staggered (i.e., not aligned), and the first locking holes 202 and the second locking holes 204 are staggered (i.e., not aligned). This arrangement makes it easy to install electrical connectors on both opposite sides of the circuit board 200 to achieve a modular arrangement.

In the illustrated embodiment of the present invention, the electrical connector 101 is a high-speed connector, such as a QSFP connector, an SFP connector, an OSFP connector, or an OSFP-DD connector. Of course, in other embodiments, the electrical connector 101 may also be a connector of other types. In the illustrated embodiment of the present invention, the electrical connector 101 includes an insulating body 1 and a plurality of conductive terminals 2 fixed to the insulating body 1. In the illustrated embodiment of the present invention, the electrical connector 101 is a double-layer structure, which is provided with two connector interfaces that are stacked and have the same structure. Unless otherwise specified, the following description only takes one connector interface as an example.

The main body 11 is provided with a mounting wall 111 located at the bottom, and the mounting wall 111 is provided with a mounting surface 1111 for mounting on the circuit board 200 and a plurality of slots 1112 arranged at intervals, and the slots 1112 penetrate the mounting surface 1111. The protruding portion 12 is provided with a mating surface 121 and a slot 122 penetrating the mating surface 121. The slot 122 is used to accommodate part of the mating connector (e.g., the tongue plate 400 of the mating connector).

[0054] Please combine Fig.12 As shown, the conductive terminal 2 includes an elastic contact portion 21 protruding into the slot 122 and an elastic abutting portion 22 extending toward the mounting surface 1111, the elastic abutting portion 22 protruding from the mounting surface 1111, the elastic contact portion 21 is used to contact the docking connector, and the elastic abutting portion 22 is used to abut against the conductive sheet 205 on the circuit board 200 to achieve electrical connection. The elastic abutting portion 22 passes through the corresponding slot 1112 to extend out of the mounting surface 1111. By providing the slot 1112, on the one hand, each elastic abutting portion 22 can be separated to avoid short circuit; on the other hand, the slot 1112 provides a certain deformation space for the elastic abutting portion 22, so that it is convenient for it to abut against the circuit board 200. In the illustrated embodiment of the present invention, the mounting wall 111 is separately provided from the insulating body 1 and assembled on the insulating body 1.

[0055] In the illustrated embodiment of the present invention, the conductive terminal 2 includes a connecting portion 23 connected between the elastic contact portion 21 and the elastic abutting portion 22. The connecting portion 23 is bent. The conductive terminal 2 also includes a first extension portion 24 connected between the elastic contact portion 21 and the connecting portion 23 and a second extension portion 25 connected between the connecting portion 23 and the elastic abutting portion 22, the extension direction of the first extension portion 24 is perpendicular to the extension direction of the second extension portion 25, and the extension direction of the elastic abutting portion 22 is perpendicular to the extension direction of the second extension portion 25.

In the illustrated embodiment of the present invention, the connecting portion 23 is embedded in the insulating block 26 to form a plurality of terminal modules. In the illustrated embodiment of the present invention, the terminal modules are four groups, and two of them constitute a terminal of a connector interface. As far as one connector interface is concerned, the elastic contact portions 21 located in the slot 122 are arranged in two rows, and the two rows of elastic contact portions 21 clamp a portion of the docking connector together. Of course, in other embodiments, the conductive terminal 2 can be assembled to the insulating body 1 by installation. The combination of the conductive terminal 2 and the insulating body 1 can be flexibly adjusted according to actual requirements, and this has been well known to technicians in the relevant technical field, and the present invention will not be repeated here.

[0056] Please refer to Figures 13 to 16 As shown, the metal shielding shell 102 includes a top wall 31, a bottom wall 32, a first side wall 33 connecting the top wall 31 and the bottom wall 32 on one side, a second side wall 34 connecting the top wall 31 and the bottom wall 32 on the other side, and a rear wall 35 at the rear end. The metal shielding shell 102 is generally cylindrical so as to provide a good shielding effect. The top wall 31, the bottom wall 32, the first side wall 33, and the second side wall 34 together form a receiving cavity 30 for receiving most of the docking connectors (see Figure 1 The receiving cavity 30 is communicated with the slot 122, and the receiving cavity 30 is located at the front end of the slot 122. The slot 122 and the receiving cavity 30 are used together to receive the docking connector.

[0057] In addition, the metal shielding shell 102 is provided with a plug-in surface 36 and an opening 361 exposed on the plug-in surface 36; the electrical connector 101 is also provided with a light guide 4, one end of which extends to the opening 361 and the other end is close to the circuit board 200. In this way, the light showing the working status of the circuit board 200 can be transmitted to the plug-in surface 36 through the light guide 4, so as to facilitate observation. The metal shielding shell 102 also includes elastic grounding claws 37 respectively fixed to the outer side and inner side of the top wall 31, the bottom wall 32, the first side wall 33 and the second side wall 34. The elastic grounding claw 37 is close to the plug-in surface 36, wherein the elastic grounding claw 37 located on the outside is used to connect the metal shielding shell 102 with other external grounding structures to increase the grounding area and improve the shielding effect; the elastic grounding claw 37 located on the inside protrudes into the accommodating cavity 30. Such a configuration can, on the one hand, achieve contact with the docking connector to increase the shielding area; on the other hand, it can also increase the plug-in and pull-out force that cooperates with the docking connector and improve the stability of the connection between the two.

[0058] Please refer to Fig.15 As shown, the first side wall 33 of the metal shielding shell 102 is provided with a first side edge 331, a plurality of first mounting feet 332 protruding from the first side edge 331, and a plurality of first retaining feet 333 protruding from the first side edge 331. Fig.15 The two first mounting legs 332 (on the right side in the figure) and the first buckling legs 333 are arranged alternately. The first mounting legs 332 are provided with first through holes 3321 so that the first mounting legs 332 have elasticity, so as to be pressed into the first conductive holes 201 of the circuit board 200. The first buckling legs 333 are provided with first barbs 3331, which are used to be inserted into the first buckling holes 202 of the circuit board 200 and fixed to the circuit board 200.

[0059] Please refer to Fig.16 As shown, the second side wall 34 of the metal shielding shell 102 is provided with a second side edge 341, a plurality of second mounting feet 342 protruding from the second side edge 341, and a plurality of second retaining feet 343 protruding from the second side edge 341. Fig.16The two second mounting feet 342 (on the right side of the figure) and the second buckling feet 343 are arranged alternately. The second mounting feet 342 are provided with second through holes 3421 so that the second mounting feet 342 have elasticity, so as to be pressed into the second conductive holes 203 of the circuit board 200. The second buckling feet 343 are provided with second barbs 3431, which are used to be inserted into the second buckling holes 204 of the circuit board 200 and fixed to the circuit board 200. Please further combine Figure 6 As shown, the first holding foot 333 and the second holding foot 343 are staggered along the width direction WW perpendicular to the mating direction DD, and the two first mounting feet 332 at the rear end and the two second mounting feet 342 at the rear end are staggered along the width direction WW perpendicular to the mating direction DD. This arrangement facilitates the fixed installation of the two electrical connectors on the two opposite sides of the circuit board 200 with the circuit board 200, thereby realizing a modular arrangement.

[0060] For details, please refer to Fig.19 As shown, in the illustrated embodiment of the present invention, the circuit board 200 includes a first surface 206 facing the electrical connector 101 and a second surface 207 opposite to the first surface 206, and the first locking hole 202 passes through the first surface 206. The circuit board 200 also includes a reaming hole 208 passing through the second surface 207, the reaming hole 208 is connected to the first locking hole 202, and the diameter of the reaming hole 208 is larger than the diameter of the first locking hole 202. As a result, the circuit board 200 forms a locking surface 209 at the junction of the reaming hole 208 and the first locking hole 202. When the first barb 3331 of the first buckling foot 333 is inserted into the first locking hole 202 of the circuit board 200 and installed in place, the first barb 3331 is buckled on the locking surface 209, so as to overcome the force generated when the elastic abutting portion 22 abuts against the conductive sheet 205 on the circuit board 200, and ensure the contact reliability between the elastic abutting portion 22 and the circuit board 200. In the illustrated embodiment of the present invention, the first barb 3331 is located in the expanded hole 208 and does not protrude from the second surface 207. This arrangement, on the one hand, reduces the overall height of the electrical connector 101 after it is installed on the circuit board 200; on the other hand, it also reduces the risk of the first retaining foot 333 being damaged by external force.

[0061] Please refer to Fig.17 and Fig.18As shown, the present invention also relates to an electrical connector assembly, which includes a first electrical connector component, a circuit board 200 and a second electrical connector component 300. In the illustrated embodiment of the present invention, the first electrical connector component is the aforementioned electrical connector component 100, and the second electrical connector component 300 is the same as the first electrical connector component; of course, in other embodiments, the two may also be different. The second electrical connector component 300 includes a second electrical connector 301. The circuit board 200 is provided with a first side (e.g., a lower side), a plurality of first conductive sheets 2051 located on the first side, a second side (e.g., an upper side) opposite to the first side, and a plurality of second conductive sheets 2052 located on the second side. The first electrical connector component is mounted on the first side of the circuit board 200 and abuts against the first conductive sheet 2051, and the second electrical connector 301 is mounted on the second side of the circuit board 200 and electrically connected to the second conductive sheet 2052. In one embodiment of the present invention, the conductive terminal 302 of the second electrical connector 301 elastically abuts against the second conductive sheet 2052. In this arrangement, since the first conductive sheet 2051 and the second conductive sheet 2052 are respectively arranged on two opposite surfaces of the circuit board 200, it is easy to arrange; in addition, this arrangement avoids setting up and down through holes in the area where the conductive terminal is electrically connected to the circuit board 200, thereby reducing the adverse effect on signal transmission.

[0062] The above implementation modes are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on the technical personnel in the relevant technical field. Although the present invention has been described in detail in this specification with reference to the above implementation modes, the ordinary technical personnel in the field should understand that the technical personnel in the relevant technical field can still modify or replace the present invention with equivalents, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
