Referring to fig. 5 to 8, in the first embodiment of the present invention, the first shielding shell 421 is provided with a bare area 4211, after the electrical connector 2 is completely mated with the mating connector 6, each of the first terminal assemblies 42 is mated with a corresponding one of the second terminal assemblies 62, the first contact portion 4221 is mated with the second contact portion 6221, the second contact portion 6221 exposes the bare area 4211 of the first shielding shell 421, and the second shielding shell 621 is disposed outside the first shielding shell 421 and covers the bare area 4211. It should be noted that the shielding of the bare area 4211 by the second shielding shell 621 means that the bare area 4211 is shielded by the second shielding shell 621, so that the bare area 4211 has no gap communicating with the outside.

Further, after the electrical connector 2 is mated with the mating connector 6, the second shielding shell 621 covers the outer side of the first shielding shell 421 and shields the bare area 4211, so that the first shielding shell 421 and the second shielding shell 621 can jointly shield the electrical connection assembly 1 from interference signals, and the high-frequency performance of the electrical connection assembly 1 is enhanced.

It should be noted that the second shielding shell 621 is disposed on the bare area 4211, and in the present invention, the second shielding shell 621, which is a tubular structure, is disposed outside the first shielding shell 421 and covers the bare area 4211; in other embodiments, the second shielding shell 621 may also extend a sheet-shaped extension (not shown) to cover the empty area 4211, which is not limited herein. In the first embodiment, when the electrical connector 2 is completely mated with the mating connector 6, the second contact portion 6221 is located above the first contact portion 4221, and accordingly, the bare region 4211 is located on the first main body surface 4212 of the first shielding shell 421; in other embodiments, after the electrical connector 2 is completely mated with the mating connector 6, the second contact portion 6221 may also be located below the first contact portion 4221, and accordingly, the bare area 4211 is located on the second main body surface 4213 of the first shielding shell 421, so as to expose the second contact portion 6221 to the bare area 4211, which is not limited herein.

Referring to fig. 4 and 5, in the first embodiment, the first contact portion 4221 has a first bending section 42211, a first contact section 42212, a second bending section 42213, a second contact section 42214 and a guiding section sequentially extending (i.e., sequentially extending forward) along the extending direction of the first contact portion 4221, the second contact portion 6221 has a first bending section 62211, a first contact section 62212, a second bending section 62213, a second contact section 62214 and a guiding section sequentially extending (i.e., sequentially extending backward) along the extending direction of the second contact portion 6221, the second contact section 42214 of the first contact portion 4221 is close to the end of the first contact portion 4221 relative to the first contact section 42212 of the first contact portion 4221, the second contact section 62214 of the second contact portion 6221 is close to the end of the second contact portion 6221 relative to the first contact section 6225 of the second contact portion 6221, the guide segment of the first contact portion 4221 serves as a first guide segment 42215, the guide segment of the second contact portion 6221 serves as a second guide segment 62215, the first guide segment 42215 is bent and extended from the second contact segment 42214 of the first contact portion 4221, and the second guide segment 62215 is bent and extended from the second contact segment 62214 of the second contact portion 6221. In this embodiment, the second guiding segment 62215 is exposed at the bare area 4211 of the first shielding case 421, and the second shielding case 621 shields the bare area 4211. Therefore, during the mating process, the first and

second signal terminals

422 and 622 are favorably mated by the guiding action of the first and second guiding

sections

42215 and 62215. Since the first guide segment 42215 is bent and extended toward the first body surface 4212 of the first shield case 421 and the second guide segment 62215 is bent and extended toward the second body surface 4213 of the first shield case 421, if the bare region is not provided, the first guide segment 42215 and the second guide segment 62215 are more easily contacted to the first shield case 421. The second guiding segment 62215 of the first embodiment of the present invention is exposed in the bare area 4211, so that the second guiding segment 62215 can be prevented from contacting the first shielding case 421 to short-circuit the second signal terminal 622; meanwhile, compared with the first shielding case 421 without the bare area 4211, in the present invention, since the second guide segment 62215 is exposed in the bare area 4211, on the premise that the second guide segment 62215 does not contact the second shielding case 621, the length of the second guide segment 62215 is designed in a wider range, which is beneficial to increasing the length of the second guide segment 62215 according to actual needs and expanding the designed range of the length of the second guide segment 62215. It should be noted that, in the first embodiment of the present invention, the second guiding segment 62215 is exposed in the bare area 4211, the second shielding shell 621 shields the bare area 4211, in other embodiments, the first guide segment 42215 may also be exposed in the bare area 4211, or the first guide segment 42215 and the second guide segment 62215 respectively expose the corresponding bare area 4211, so as to prevent the first signal terminal 422 or the second signal terminal 622 from contacting the first shielding case 421, prevent the first signal terminal 422 or the second signal terminal 622 from being short-circuited, and it is advantageous to increase the length of the first guide segment 42215 or the second guide segment 62215 according to actual needs, and to expand the designable range of the lengths of the first guide segment 42215 and the second guide segment 62215.

Further, the first contact portion 4221 extends forward from the first connection portion 4222 and bends towards a direction away from the second contact portion 6221, so that when the second contact portion 6221 contacts with the surface of the first contact portion 4221, the second contact portion 6221 can further be away from the first shielding case 421 and the second shielding case 621, thereby further avoiding the second contact portion 6221 from contacting with the first shielding case 421 and the second shielding case 621, and effectively preventing the second signal terminal 622 from being short-circuited. For example, the distance between the upper side of the second contact portion 6221 of the present embodiment and the first shielding case 421 or the second shielding case 621 is further increased, and the second contact portion 6221 is prevented from upwardly contacting the first shielding case 421 or the second shielding case 621. The second contact portion 6221 extends from the second connection portion 6222 toward the extending direction of the second signal terminal 622 and bends toward a direction away from the first contact portion 4221, so that when the first contact portion 4221 contacts the surface of the second contact portion 6221, the first contact portion 4221 can further be away from the first shielding case 421 and the second shielding case 621, and the first contact portion 4221 is further prevented from contacting the first shielding case 421 and the second shielding case 621, thereby effectively preventing the first signal terminal 422 from being short-circuited. For example, the distance between the lower side of the first contact portion 4221 and the first shield case 421 and the second shield case 621 of the present embodiment is further increased, and the first contact portion 4221 is prevented from contacting the first shield case 421 or the second shield case 621 downward.

Referring to fig. 3 to 5, in the first embodiment, the first bending section 42211 and the second bending section 42213 of the first contact portion 4221 are both bent away from the second contact portion 6221, the first bending section 62211 and the second bending section 62213 of the second contact portion 6221 are both bent away from the first contact portion 4221, when the electrical connector 2 is completely mated with the mating connector 6, the second contact section 42214 of the first contact portion 4221 contacts the first contact section 62212 of the second contact portion 6221, and the second contact section 62214 of the second contact portion 6221 contacts the first contact section 42212 of the first contact portion 4221. Therefore, the first contact part 4221 is bent twice in the direction away from the second contact part 6221, and the second contact part 6221 is bent twice in the direction away from the first contact part 4221, so that the first contact part 4221 and the second contact part 6221 can be prevented from colliding with each other in the butt joint process, double-point contact can be realized, and the timber pile effect can be reduced.

Referring to fig. 5, 8 to 9, in the first embodiment, the first insulating block 423 has two first supporting portions 4231, the first supporting portions 4231 extend forward beyond the first bending section 42211 of the first contact portion 4221, and the first supporting portions 4231 are located on opposite sides of a contact surface of the first contact section 42212 and support the first contact portion 4221; the second insulating block 623 has two second supports 6231, the second supports 6231 extending toward the electrical connector 2 and beyond the first bent section 62211 of the second contact portion 6221, the second supports 6231 being located on the opposite side of the contact surface of the first contact section 62212 and supporting the second contact portion 6221. Thus, the first support portion 4231 can support the first contact portion 4221, and the second support portion 6231 can support the second contact portion 6221, so that the strength of the first contact portion 4221 and the second contact portion 6221 is increased, the degree of elastic deformation of the first contact portion 4221 and the second contact portion 6221 is also limited, the first shield case 421 is prevented from being excessively pressed against each other during docking, and the first contact portion 4221 and the second contact portion 6221 are further prevented from being short-circuited. In the present embodiment, the second contact portion 6221 is located above the first contact portion 4221, the first support portion 4231 supports the lower surface of the first contact portion 4221 upward, and the second support portion 6231 supports the upper surface of the second contact portion 6221 downward; in other embodiments, the second contact portion 6221 may be located below the first contact portion 4221, and the first support portion 4231 supports the upper surface of the first contact portion 4221 downward, and the second support portion 6231 supports the lower surface of the second contact portion 6221 upward, which is not limited herein.

Referring to fig. 3 to 5, in the first embodiment, the first guiding section 42215 is forward beyond the first shielding shell 421, when the electrical connector 2 is completely mated with the mating connector 6, the second contacting section 62214 of the second contacting portion 6221 contacts the first contacting section 42212 of the first contacting portion 4221, and the second guiding section 62215 is exposed to the bare area 4211 and shielded by the second shielding shell 621. Therefore, compared with the need of providing the bare areas 4211 at the positions of the first shielding shell 421 corresponding to the first guide segment 42215 and the second guide segment 62215, the first shielding shell 421 of the present invention does not need to provide the bare areas 4211 at the positions corresponding to the first guide segment 42215, and only needs to provide the bare areas 4211 at the positions corresponding to the second guide segment 62215, so that the first guide segment 42215 and the second guide segment 62215 can be prevented from contacting the first shielding shell 421 to cause short circuit, the number of the bare areas 4211 can be reduced, the manufacturing processes can be reduced, and the production efficiency of the electrical connector 2 can be improved. Moreover, compared to the first shielding case 421 without the bare area 4211, but the first shielding case 421 is entirely located behind the first contact section 42212 of the first contact portion 4221, the first shielding case 421 of the present invention has a larger contact area to make abutting contact with the second shielding case 621, for example, the second main body surface 4213 of the first shielding case 421 in the first embodiment of the present invention provides a larger contact area to make contact with the second shielding case 621, and the first shielding case 421 can be more enclosed around the first contact portion 4221, so as to better shield the first contact portion 4221 from interference signals.

Referring to fig. 6 to 8 and fig. 10(a) to 10(B), in the first embodiment, the first shielding shell 421 has two first side surfaces 4214, two main body surfaces and four arc-shaped transition surfaces 4215, which are oppositely arranged, the two main body surfaces are oppositely arranged in the up-down direction Z, and the two first side surfaces 4214 are oppositely arranged in the left-right direction Y. The upper main body surface is used as a first main body surface 4212, and the lower main body surface is used as a second main body surface 4213, wherein two sides of the first main body surface 4212 are connected with the corresponding first side surface 4214 through two arc transition surfaces 4215, and two sides of the second main body surface 4213 are connected with the corresponding first side surface 4214 through the other two arc transition surfaces 4215. The second shielding case 621 has two second side surfaces 6213 oppositely disposed in the left-right direction Y, each second side surface 6213 has an opening 6214, and an elastic piece 6215 is integrally formed by extending from an inner edge of each opening 6214, wherein, after the electrical connector 2 is completely mated with the mating connector 6, each elastic piece 6215 is inwardly abutted to the corresponding first side surface 4214, and each first side surface 4214 shields the corresponding opening 6214. Therefore, the elastic pieces 6215 of the two second side surfaces 6213 abut against the two first side surfaces 4214, so that the first shielding shell 421 and the second shielding shell 621 can be stably contacted, and the opening 6214 is shielded by the first side surfaces 4214, so that the first signal terminal 422 and the second signal terminal 622 can be prevented from being interfered by external signals due to the arrangement of the opening 6214. Further, the second shielding case 621 further has a third main body surface 6211 and a fourth main body surface 6212 which are oppositely arranged in the up-down direction Z, the third main body surface 6211 is located above and connected to the two second side surfaces 6213, the fourth main body surface 6212 is located below and connected to the two second side surfaces 6213, and the second shielding case 621 forms a tubular structure. The third body surface 6211 of the second shield case 621 has two inwardly protruding protrusions 6216, each protrusion 6216 inwardly abuts against the first body surface 4212 of the first shield case 421, and the fourth body surface 6212 of the second shield case 621 also has a resilient piece 6215 inwardly abutting against the second body surface 4213 of the first shield case 421, so that the contact stability between the first shield case 421 and the second shield case 621 can be further increased.

Referring to fig. 6 to 8, in the first embodiment, the bare area 4211 is recessed rearward from the front end of the first main body surface 4212, each first side surface 4214 is provided with a notch 42141 communicated with the bare area 4211, the notch 42141 is disposed between the first side surface 4214 and the arc transition surface 4215 on the same side, the connection position of the arc transition surface 4215 and the first side surface 4214 is shown as a connection line L, the front end of the first side surface 4214 extends beyond the connection line L in the direction of the bare area 4211, and the front end of the first side surface 4214 shields the corresponding opening 6214. In this embodiment, the bare area 4211 is located above, so that the front end of the first side surface 4214 extends upward beyond the connection line L, in other embodiments, the bare area 4211 may be located below, and the front end of the first side surface 4214 extends downward beyond the connection position of the first side surface 4214 and the corresponding arc transition surface 4215, which is not limited herein. Thus, spacing the front end of the first side surface 4214 and the arcuate transition surface 4215 by the notch 42141 facilitates molding the front end of the first side surface 4214 to extend beyond the connecting line L in a direction toward the bare space 4211, increasing the area of the front end of the first side surface 4214 to contact or shield the opening 6214 with the second shielding shell 621. Moreover, if first shielding shell 421 is cutting out at first the material of a slice formula naked regional 4211, then buckle out arc transition surface 4215, because arc transition surface 4215 is the arc crooked, if not set up notch 42141, both can cause the front end of first side 4214 to exceed the part of connecting wire L is difficult to the shaping and goes out the arc line, again makes the linking position of a plurality of edges of naked regional 4211 is torn easily, consequently, notch 42141 will the front end of first side 4214 with arc transition surface 4215 is spaced apart, has the transition, is favorable to the shaping of first shielding shell 421.

Referring to fig. 8, in the first embodiment, the first shielding shell 421 includes two U-shaped shielding bodies 4216, the two U-shaped shielding bodies 4216 are assembled with each other to form a tubular structure, the bare region 4211 is formed in one of the U-shaped shielding bodies 4216, the second shielding shell 621 forms a tubular structure, and when the electrical connector 2 and the mating connector 6 are mated, the first shielding shell 421 and the second shielding shell 621 are mated to each other and completely cover the first contact portion 4221 and the second contact portion 6221. Therefore, compared with the problem that when the bare area 4211 is cut in an integral tubular structure, the positioning is not good and the tubular first shielding shell 421 is easy to extrude and deform, the bare area 4211 is formed by molding one U-shaped shielding body 4216, and the two U-shaped shielding bodies 4216 are assembled to form a tubular structure, so that the U-shaped shielding body 4216 can be conveniently positioned when the bare area 4211 is molded, the problem that the first shielding shell 421 is extruded and deformed when the bare area 4211 is molded is avoided, and the processing difficulty can be reduced; meanwhile, the second shielding case 621 and the first shielding case 421 together completely cover the first contact portion 4221 and the second contact portion 6221, so that external interference signals can be effectively shielded for the first contact portion 4221 and the second contact portion 6221, and the high-frequency performance of the electrical connection assembly 1 is further improved. The first side 4214 is formed by joining the sides of the U-shaped shield 4216.

Referring to fig. 1 to 4, the first signal terminals 422 of the electrical connector 2 are soldered to the first substrate 7 by solder balls, so that the first signal terminals 422 of the electrical connector 2 have better coplanarity. The electrical connector 2 further includes a planar body 5, the planar body 5 is fixed to the insulating bodies 41 of the plurality of electrical modules 4, and an upper surface of the planar body 5 is a horizontal surface. Thus, when the electrical connector 2 is soldered to the first substrate 7, the planar body 5 provides a horizontal surface for a vacuum chuck (not shown) to suck and move to the first substrate 7, so that the first signal terminals 422 are soldered to the first substrate 7 by solder balls.

Referring to fig. 8, the first insulation block 423 includes a first injection molded part 4232 and a second injection molded part 4233, and after the first injection molded part 4232 is molded on the first connection part 4222, the second injection molded part 4233 is molded on the first injection molded part 4232 and the first signal terminal 422. The first injection-molded part 4232 has a plurality of fixing portions by which a mold fixes the first signal terminal 422 and the first injection-molded part 4232 in position when the second injection-molded part 4233 is molded. Specifically, the plurality of fixing portions include a first fixing portion 42321 and a second fixing portion 42322, and when the second injection-molded part 4233 is molded, the first injection-molded part 4232 and the first signal terminal 422 are fixed in the vertical direction Z by the first fixing portion 42321, and the first injection-molded part 4232 and the first signal terminal 422 are fixed in the left-right direction Y by the second fixing portion 42322. It should be noted that, if the first insulating block 423 is formed by only one injection molding process, and the mold clamps the first signal terminal 422 for positioning, after the molding, the mold is removed, and the position where the first signal terminal 422 is clamped by the mold is exposed to the first insulating block 423, so that the media around the first connection portion 4222 are different, which may affect the impedance consistency of the first signal terminal 422. The second injection molding piece 4233 of the invention does not need a mold to clamp the first signal terminal 422 during molding, and after the first insulating block 423 is completely molded, the first connection portion 4222 can be completely coated in an insulating material, and the media around the first connection portion 4222 are the same, which is beneficial to the impedance consistency of the first connection portion 4222.

Referring to fig. 11(a) to 11(B), which are schematic diagrams of a second embodiment provided by the present invention, the second embodiment is different from the first embodiment in that the first shielding shell 421 is provided with two bare areas 4211, when the first terminal assembly 42 and the second terminal assembly 62 are completely mated, the first contact portion 4221 is exposed in one of the bare areas 4211, the second contact portion 6221 is exposed in the other bare area 4211, and both of the bare areas 4211 are shielded by the second shielding shell 621. Thus, the first contact portion 4221 and the second contact portion 6221 of the second embodiment of the present invention are respectively exposed to the two bare regions 4211 of the first shielding case 421, so that neither the first contact portion 4221 nor the second contact portion 6221 can contact the first shielding case 421 in the up-down direction, and the first contact portion 4221 and the second contact portion 6221 are prevented from contacting the first shielding case 421 to be short-circuited; meanwhile, the second shielding case 621 shields the bare area 4211, and the first contact part 4221 and the second contact part 6221 are prevented from being affected by external interference signals due to the arrangement of the bare area 4211.

Referring to fig. 12(a) to 12(B), which are schematic diagrams of a third embodiment provided by the present invention, the third embodiment is different from the first embodiment in that the first shielding shell 421 is provided with one bare area 4211, after the first terminal assembly 42 and the second terminal assembly 62 are completely mated, the first contact portion 4221 is exposed in the bare area 4211, and the bare areas 4211 are all shielded by the second shielding shell 621. Thus, the first contact part 4221 of the third embodiment of the present invention is exposed to the bare area 4211 of the first shielding case 421, so that the first contact part 4221 does not contact the first shielding case 421 downward, preventing the first contact part 4221 from contacting the first shielding case 421 to be short-circuited; meanwhile, the second shielding case 621 shields the bare area 4211, and the first contact portion 4221 is prevented from being affected by an external interference signal due to the arrangement of the bare area 4211.

In the third embodiment, the second contact portion 6221 is a flat plate shape, and the first contact portion 4221 is a bent elastic contact portion, it can be understood that the risk of short circuit due to the second contact portion 6221 contacting the first shielding case 421 is relatively low, compared to the case where the second contact portion 6221 is also a bent elastic contact portion, and the first shielding case 421 is adapted to provide the bare region 4211 only for the first contact portion 4221. However, when the height of the first shielding case 421 in the vertical direction Z is relatively small to further miniaturize the electrical connector 2, even if the first contact portion 4221 or the second contact portion 6221 has a flat plate-like structure, there is a risk that the first shielding case 421 is contacted after being butted, and in this case, the bare region 4211 may be provided corresponding to the flat plate-like first contact portion 4221 or the flat plate-like second contact portion 6221. Further, when both the first contact portion 4221 and the second contact portion 6221 are bent elastic contact portions, the blank region 4211 may be provided only for one of the first contact portion 4221 and the second contact portion 6221, for example, when the first guide section 42215 of the first contact portion 4221 is relatively long, the second guide section 62215 of the second contact portion 6221 is relatively short, and the second contact portion 6221 is sufficiently distant from the first shield shell 421, even if the second contact portion 6221 is a bent elastic contact portion, the blank region 4211 may not be provided for the second contact portion 6221, and the blank region 4211 may be provided only for the first contact portion 4221. Therefore, the three embodiments of the present invention are only illustrative of several cases of the present invention, and the shapes of the first contact portion 4221 and the second contact portion 6221, and the number and positions of the bare areas 4211 of the first shielding shell 421 may be set in different combinations according to actual needs. That is, the first shield shell 421 may be provided with the bare area 4211 corresponding to the flat plate-shaped contact portion, or may not be provided with the bare area 4211 corresponding thereto; similarly, for the bent elastic contact portion, the first shielding shell 421 may be provided with the bare area 4211 correspondingly, or may not be provided with the bare area 4211 correspondingly, and three embodiments of the present invention are merely schematic and are not limited.

In the above three embodiments, the first contact portion 4221 and the second contact portion 6221 both abut against each other in the vertical direction Z, and the vertical direction Z is defined as a direction in which the first contact portion 4221 and the second contact portion 6221 abut against each other; in another embodiment, the first contact portion 4221 and the second contact portion 6221 may abut against each other in the left-right direction Y or the front-back direction X, and the left-right direction Y or the front-back direction X may be taken as a direction in which the first contact portion 4221 and the second contact portion 6221 abut against each other, so that the vacant region 4211 of the first shield shell 421 may be provided at a position corresponding to the first contact portion 4221 or the second contact portion 6221, which is not limited herein. The empty area 4211 is not limited to be recessed rearward from the front end of the first shielding case 421, and the empty area 4211 may be a circular or polygonal hole (not shown) surrounding it.

In summary, the electrical connection assembly 1 provided by the present invention has the following beneficial effects:

The first shielding case 421 covers the outside of the first signal terminal 422, and can shield the first signal terminal 422 from an interference signal, thereby improving the high-frequency performance of the electrical connector 2; the second shielding case 621 covers the outside of the second signal terminal 622, and can shield the second signal terminal 622 from interference signals, thereby improving the high-frequency performance of the docking connector 6. Further, after the electrical connector 2 is mated with the mating connector 6, the second shielding shell 621 covers the outer side of the first shielding shell 421 and shields the bare area 4211, so that the first shielding shell 421 and the second shielding shell 621 can jointly shield the electrical connection assembly 1 from interference signals, and the high-frequency performance of the electrical connection assembly 1 is enhanced.

Also, since the first guide segment 42215 is bent and extended toward the first body surface 4212 of the first shield case 421 and the second guide segment 62215 is bent and extended toward the second body surface 4213 of the first shield case 421, if the bare area is not provided, the first guide segment 42215 and the second guide segment 62215 are more easily contacted to the first shield case 421. The first guide segment 42215 or the second guide segment 62215 of the present invention is exposed in the bare area 4211 of the first shielding case 421, or both the first guide segment 42215 and the second guide segment 62215 are exposed in the bare area 4211 of the first shielding case 421, so that the first guide segment 42215 or the second guide segment 62215 can be prevented from contacting the first shielding case 421, and the first signal terminal 422 or the second signal terminal 622 can be prevented from being shorted; meanwhile, on the premise that the first guide segment 42215 and the second guide segment 62215 do not contact the second shielding shell 621, the length design range of the first guide segment 42215 and the second guide segment 62215 is wider, which is beneficial to increasing the length of the first guide segment 42215 and the second guide segment 62215 according to actual needs and expanding the design range of the length of the first guide segment 42215 and the second guide segment 62215.

3.

4. Each elastic piece 6215 of the second side surface 6213 abuts against the corresponding first side surface 4214 inwards, and each first side surface 4214 shields the corresponding opening 6214, so that the first shielding case 421 and the second shielding case 621 can be stably butted, and the first signal terminal 422 and the second signal terminal 622 are prevented from being interfered by external signals due to the arrangement of the openings 6214.

5. The notch 42141 is disposed between the first side surface 4214 and the arc transition surface 4215 on the same side, the front end of the first side surface 4214 extends towards the bare space 4211 beyond the connection position of the arc transition surface 4215 and the first side surface 4214, the front end of each first side surface 4214 covers the corresponding opening 6214, the contact area between the first side surface 4214 and the second side surface 6213 can be increased, and the first side surface 4214 can better cover the opening 6214.
