Description
Technical Field
The utility model relates to an electric connector.
Background
With the development of technology, a variety of connectors for different electronic products have been developed. At present, the TYPE-C connector is widely used as a connector capable of realizing positive and negative insertion. However, the shielding sheet structure of the current TYPE-C connector is closer to the high-speed transmission terminal, which easily affects the high-frequency characteristics of the TYPE-C connector, and the shielding sheet of the current TYPE-C connector is easily deformed by compression after being butted and pressed with another connector, thereby having a collapsing problem.
Disclosure of Invention
The utility model provides an electric connector with good high-frequency characteristics.
The electric connector comprises an insulating body, a plurality of terminals and a shielding sheet. The plurality of terminals are arranged on the insulating body and comprise a plurality of high-speed signal transmission terminals. Each terminal has a mating end for mating with another electrical connector along a mating axis. The shielding sheet is partially overlapped on the insulating body. The shielding piece comprises a sheet body, a hollow part, two first sheet-shaped buckles and one second sheet-shaped buckle. Wherein, one first sheet-shaped bend, the sheet-shaped body, the other first sheet-shaped bend and the second sheet-shaped bend are sequentially connected in a ring manner to form a hollow-out part. The hollowed-out part covers the butt joint ends of the terminals. The first sheet-like bendings correspond to the high-speed signal transmission terminals along the butt joint axial direction. The butt joint end of each high-speed signal transmission terminal has a distance I relative to the joint edge of the first sheet-shaped bending part and the hollow part. The second sheet-shaped bend corresponds to the rest of the terminals along the butt joint axial direction. And each butt joint end of the other terminals has a second distance from the joint edge of the second sheet-shaped bent part and the hollow part. The first distance is greater than the second distance.
Preferably, each of the first sheet bends has a first elastic sheet portion and a first connecting portion. The first elastic piece portion is connected with the first connecting portion along the butt joint axial direction. The first connecting part is connected between the second sheet-shaped bend and the sheet-shaped body.
Preferably, the second sheet-like bend has a second spring piece portion and a second connecting portion. The second elastic piece part is connected with the second connecting part along the butt joint axial direction. The second connecting portion is connected between the two first connecting portions bent in the two first sheet shapes.
Preferably, the second tab portion has a necked-down profile near the second connection portion.
Preferably, the second sheet fold also has two projections. The two protruding parts extend from the second connecting part back to the hollow part and gradually leave away from the second elastic sheet part.
Preferably, each of the first connecting portions of the first sheet-like bent has a notch facing the hollow portion.
Preferably, in the butt joint axial direction, a third distance exists between the connecting edge of the sheet-shaped body and the hollow portion and the connecting edge of the hollow portion relative to the first sheet-shaped bend, and a fourth distance exists between the connecting edge of the sheet-shaped body and the hollow portion and the connecting edge of the hollow portion relative to the second sheet-shaped bend. Distance three is greater than distance four.
Preferably, the hollow-out portion is divided into a first region and a second region. The first region is adjacent to the position between the first sheet-shaped bend and the sheet-shaped body along the butt joint axial direction. The second region is abutted between the second sheet-shaped bend and the sheet-shaped body along the butt joint axial direction. The size of the first area along the butt joint axial direction is larger than that of the second area along the butt joint axial direction.
Preferably, the device further comprises a housing having a positioning groove and an accommodating space. The shielding sheet has a positioning portion vertically connected to the sheet body. The positioning part is embedded in the positioning groove of the shell. The accommodating space of the housing accommodates the insulating body, the terminals and the shielding sheet.
Preferably, the sheet-like body is located on a plane. The distance between the butt joint end of each high-speed signal transmission terminal orthographically projected on the plane and the joint edge of the first sheet-shaped bend and the hollow part orthographically projected on the plane is greater than the distance between each butt joint end of the other terminals orthographically projected on the plane and the joint edge of the second sheet-shaped bend and the hollow part orthographically projected on the plane.
Based on the above, in the electrical connector of the present invention, the distance between the shielding plate and the high-speed signal transmission terminal can be adjusted by the structural design of the shielding plate, so that the high-speed signal transmission terminal is far away from the shielding plate relative to the other terminals, thereby preventing the high-frequency characteristics of the electrical connector from being affected by the close proximity between the high-speed signal transmission terminal and the shielding plate. Therefore, compared with the structure relationship between the shielding plate and the high-speed signal transmission terminal in the conventional electric connector, the shielding plate of the electric connector of the utility model is far away from the high-speed signal transmission terminal and has good high-frequency characteristics.

Referring to fig. 1 and fig. 2, in the present embodiment, the electrical connector 100 includes an insulating body 110, a plurality of terminals 120, a shielding plate 130 and a housing 140. The terminals 120 are disposed on the insulating body 110 along the Z-axis, and the shielding plate 130 is partially stacked on the insulating body 110 along the Z-axis. The housing 140 includes an inner shell 142 and an outer shell 144.

During the manufacturing process of the electrical connector 100, the first member 111 is combined with the terminals 120, and the second member 112 is sandwiched between the terminals 120 and the shield plate 130. In the present embodiment, the first component 111 and the terminals 120 are combined by, for example, insert molding (insert molding), but not limited thereto. In other embodiments, first component 111 and second component 112 may be integrally formed structures.
Fig. 3 is a partially enlarged top view of a portion of the components of the electrical connector of fig. 1. Fig. 4 is a top view of a shield blade of the electrical connector of fig. 1. It should be noted that, for clarity of illustrating the structural relationship of the electrical connector 100, fig. 3 only shows the plurality of terminals 120, the shielding plate 130 and the inner shell 142 of the housing 140. Referring to FIG. 3, in the present embodiment, the terminals 120 include a plurality of high-speed signal transmission terminals 122, i.e., SuperSpeed differential signal #1(TX1+, TX1-, RX1+ and RX1-) and SuperSpeed differential signal #2(TX2+, TX2-, RX2+ and RX 2-). The high-speed signal transmission terminals 122 have a mating end T1, and the remaining terminals 124 (non-high-speed signal transmission terminals) have a mating end T2. The mating ends T1 of the high-speed signal transmission terminals 122 and the mating ends T2 of the remaining terminals 124 are adapted to be connected to another electrical connector (not shown) along a mating axis (i.e., along the X axis).
It should be noted that the high-speed signal transmission terminals 122 and the rest of the terminals 124 are arranged along the arrangement axis (i.e., along the Y axis), and the abutting ends T1 of the high-speed signal transmission terminals 122 and the abutting ends T2 of the rest of the terminals 124 are flush with each other in the arrangement axis (i.e., the Y axis). The ground terminal shielded by the other members in fig. 3 also belongs to the other terminals 124.
Referring to fig. 4, in the present embodiment, the shielding plate 130 includes a plate-shaped body 131, a hollow portion 132, two first plate-shaped bends 133, and one second plate-shaped bend 134. The two first sheet-shaped bends 133 and the one second sheet-shaped bend 134 are arranged along the arrangement axis (i.e. along the Y axis), and one of the first sheet-shaped bends 133, the sheet-shaped body 131, the other first sheet-shaped bend 133 and the second sheet-shaped bend 134 are sequentially connected in a loop to form the hollow portion 132. Here, the sheet-shaped body 131, the two first sheet-shaped folds 133 and the one second sheet-shaped fold 134 are, for example, integrally formed, but not limited thereto.
In detail, referring to fig. 3, in the present embodiment, the hollow portion 132 covers the butt ends T1 and T2 of the terminals 120 along the Z axis. The first plate-shaped bends 133 correspond to the high-speed signal transmission terminals 122 along the mating axial direction (i.e., along the X-axis), and the second plate-shaped bends 134 correspond to the other terminals 120 along the mating axial direction (i.e., along the X-axis). The abutting end T1 of each high-speed signal transmission terminal 122 is located a distance D1 from the edge E1 of the first plate-shaped bend 133 and the hollow portion 132, and each abutting end T2 of the remaining terminals 124 is located a distance D2 from the edge E2 of the second plate-shaped bend 134 and the hollow portion 132, and the distance D1 is greater than the distance D2.
In other words, in the present embodiment, the sheet-like body 131 is located on the X-Y plane, and the through-holes 132 projected on the X-Y plane cover the butt ends T1 and T2 of the terminals 120 projected on the X-Y plane. Thus, the distance D1 between the butt-joint end T1 of each high-speed signal transmission terminal 122 orthographically projected on the X-Y plane and the first sheet-shaped bend 133 orthographically projected on the X-Y plane and the edge E1 of the hollow portion 132 is greater than the distance D2 between each butt-joint end T2 of the remaining terminals 124 orthographically projected on the X-Y plane and the second sheet-shaped bend 134 orthographically projected on the X-Y plane and the edge E2 of the hollow portion 132.
More specifically, referring to fig. 3 and fig. 4, in the present embodiment, the hollow portion 132 is divided into a first area 132-1 and a second area 132-2. The first region 132-1 is adjacent to and between the first sheet fold 133 and the sheet body 131 along the butt axial direction (i.e., along the X-axis), and the second region 132-2 is adjacent to and between the second sheet fold 134 and the sheet body 131 along the butt axial direction (i.e., along the X-axis). The first region 132-1 and the second region 132-2 respectively cover the mating ends T1 of the high-speed signal transmission terminals 122 and the mating ends T2 of the remaining terminals 124 along the Z-axis, and the dimension of the first region 132-1 along the mating axis (i.e., along the X-axis) is greater than the dimension of the second region 132-2 along the mating axis (i.e., along the X-axis).
That is, as shown in fig. 4, in the butt axial direction (i.e., the X axial direction), the distance between the edge E3 of the sheet-shaped body 131 and the hollow portion 132 and the distance between the edge E1 of the hollow portion 132 and the first sheet-shaped bend 133 are three D3, the distance between the edge E3 of the sheet-shaped body 131 and the hollow portion 132 and the edge E2 of the hollow portion 132 and the distance between the three D3 and the distance between the second sheet-shaped bend 134 are four D4, and the distance between the three D3 and the distance between the three D4 are greater than the distance between the four D4.
Therefore, in the present embodiment, the electrical connector 100 can adjust the distance between the shielding plate 130 and the high-speed signal transmission terminal 122 by the structural design of the shielding plate 130, so as to prevent the high-frequency characteristics of the electrical connector 100 from being affected by the close proximity between the high-speed signal transmission terminal 122 and the shielding plate 130. Accordingly, compared to the structure relationship between the shielding plate and the high-speed signal transmission terminal in the conventional electrical connector, the shielding plate 130 of the electrical connector 100 of the present embodiment is far away from the high-speed signal transmission terminal 122 and has good high-frequency characteristics.
In addition, referring to fig. 2 and fig. 3, in the present embodiment, the shielding plate 130 further has two positioning portions 135 vertically connected to the sheet-shaped body 131 along the Z axis, and the inner shell 142 of the housing 140 further has two positioning slots 142-1 respectively corresponding to the two positioning portions 135. Each positioning portion 135 is fitted in a corresponding positioning groove 142-1 to limit the movement of the shielding plate 130 in the mating axial direction (i.e., X-axis direction) and the arrangement axial direction (i.e., Y-axis direction).
The shielding sheet 130 is further described below.
Referring to fig. 4, in the present embodiment, each of the first sheet-shaped bends 133 has a first elastic piece portion 133-1 and a first connecting portion 133-2, and the first elastic piece portion 133-1 is connected to the first connecting portion 133-2 along a butt-joint axial direction (i.e., an X-axis direction) relative to the hollow portion 132. The second sheet-shaped bend 134 has a second elastic sheet portion 134-1 and a second connecting portion 134-2, and the second elastic sheet portion 134-1 connects the second connecting portion 134-2 with respect to the hollow portion 132 along the butt axial direction (i.e., the X axial direction). The second connecting portion 134-2 of the second sheet-like bend 134 is connected between the two first connecting portions 133-2 of the two first sheet-like bends 133, and the first connecting portion 133-2 of one first sheet-like bend 133, the sheet-like body 131, the first connecting portion 133-2 of the other first sheet-like bend 133, and the second connecting portion 134-2 of the second sheet-like bend 134 are sequentially connected in a loop to form the hollow portion 132.
In detail, in the present embodiment, the sheet-shaped body 131 has two recesses 131-1 facing the hollow portion 132 and respectively adjacent to the two first connecting portions 133-2, and the first connecting portion 133-2 of each first sheet-shaped bend 133 has a notch 133-3 facing the hollow portion 132. The second tab portion 134-1 of the second sheet fold 134 has a necked-down profile 134-3 near the second connection portion 134-2, and the second sheet fold 134 further has two protrusions 134-4 extending from the second connection portion 134-2 away from the hollow portion 132 and gradually away from the second tab portion 134-1, respectively.
As described above, the sheet-like body 131 and the two first sheet-like bends 133 are designed to have the recess 131-1 and the notch 133-3, so that the two first sheet-like bends 133 are structurally weakened and the two first sheet-like bends 133 have better elasticity. In addition, the second elastic piece portion 134-1 and the second connection portion 134-2 of the second sheet-shaped bend 134 are respectively designed to have a necking profile 134-3 and two protruding portions 134-4, so that the structure of the second elastic piece portion 134-1 of the second sheet-shaped bend 134 is weakened, and the stress of the second connection portion 134-2 can be dispersed in the two protruding portions 134-4, so that the two first sheet-shaped bends 133 have better elasticity and are not easy to deform. Thus, the two first sheet-shaped bends 133 and the second sheet-shaped bend 134 are prevented from being crushed and deformed when the electrical connector 100 is connected with another electrical connector (not shown). Thus, the reliability of the electrical connector 100 can be improved, and the service life of the electrical connector 100 can be increased.
In summary, in the electrical connector of the present invention, the distance between the shielding plate and the high-speed signal transmission terminal can be adjusted by the structural design of the shielding plate, so that the high-speed signal transmission terminal is far away from the shielding plate relative to the other terminals, thereby preventing the high-frequency characteristics of the electrical connector from being affected by the close proximity between the high-speed signal transmission terminal and the shielding plate. Therefore, compared with the structure relationship between the shielding plate and the high-speed signal transmission terminal in the conventional electric connector, the shielding plate of the electric connector has good high-frequency characteristics because the shielding plate is far away from the high-speed signal transmission terminal. In addition, the shielding sheet also increases the size of the connection structure of the sheet-shaped bending relative to the sheet-shaped body, which is equivalent to increasing the force arm of the sheet-shaped bending, so that when the electric connector is butted with another electric connector, the situation that the sheet-shaped bending is collapsed due to the increase of the force arm is avoided.
