Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The terminal device generally has a variety of Circuit Boards, for example, a Flexible Printed Circuit (FPC), a Printed Circuit Board (PCB), and the like. Connection needs to be established between the circuit boards for signal transmission. In this case, the connection is typically accomplished using a connector, which may be a board-to-board connector or the like. The connector generally includes a female socket 1 and a male connector 2, wherein the female socket 1 and the male connector 2 are respectively connected to different circuit boards, and then the female socket 1 and the male connector 2 are connected to transmit signals (such as radio frequency signals or digital signals). Among them, a connector for transmitting a radio frequency signal is generally called a radio frequency connector.

The embodiment of the present application provides a shielding shell 12, as shown in fig. 1, the shielding shell 12 is a component for performing electromagnetic shielding in a connector.

Signals transmitted in the connector are easily interfered by electromagnetic waves, and electromagnetic waves can be generated to interfere other components, especially in a radio frequency connector, and transmitted radio frequency signals are easily interfered or externally interfered. The shielding shell 12 utilizes the property of metallic material capable of reflecting electromagnetic waves to form a barrier around the female socket terminal 112, so as to prevent external electromagnetic waves from entering the shielding shell 12, thereby implementing electromagnetic shielding.

The material of the shielding case 12 may be a metal material with high conductivity, such as nickel-iron alloy.

The shield case 12 may surround the insertion groove 11A of the female housing body 11.

In practice, female housing terminals 112 are usually disposed in the insertion slot 11A of the female housing body 11 for signal transmission between the connector and other components in the terminal. Since signals transmitted in the connector are easily interfered by electromagnetic waves and may generate electromagnetic waves to interfere with other components, a barrier needs to be established around the female socket terminal 112 to shield the electromagnetic waves by using the property of the metal material capable of reflecting the electromagnetic waves.

The shielding shell 12 surrounds the inserting groove 11A of the female socket body 11, and can better surround the female socket terminal 112 which is easy to generate electromagnetic waves and receives external electromagnetic wave interference, thereby effectively improving the electromagnetic shielding effect of the shielding shell.

As shown in fig. 1, the surface of the shield case 12 may have a plurality of grooves 120.

In the shield shell 12, a surface, which may be remote from the female socket body 11, may have a plurality of grooves 120. Since the shielding case 12 realizes electromagnetic shielding by using the property that the metal material can reflect electromagnetic waves, the metal material with a smooth surface can only have a good shielding effect on electromagnetic waves in the direction perpendicular to the surface. Therefore, the existence of the groove 120 enables the shielding case 12 to well shield external electromagnetic waves in multiple directions, and further enhances the electromagnetic shielding effect of the shielding case 12.

The groove 120 may be machined by, but not limited to, machining, laser engraving, or wire cutting.

Alternatively, the shield shell 12 may also have a plurality of grooves 120 near the inner surface of the female socket body 11.

In this example, the plurality of grooves 120 are provided on the inner surface of the shielding shell 12, so that the electromagnetic shielding effect of the shielding shell 12 on the electromagnetic waves radiated by the female socket terminal 112 can be improved, and the electromagnetic waves radiated by the female socket terminal 112 can be prevented from affecting other components except the connector.

Alternatively, the shield case 12 may include two first shield parts 121 and two second shield parts 122, the two first shield parts 121 being disposed opposite to each other, the two second shield parts 122 being disposed opposite to each other, and each of the second shield parts 122 being connected to the two first shield parts 121, respectively.

Thus, the shielding shell 12 can surround the outside of the insertion slot 11A, so as to surround the female socket terminal 112 located in the insertion slot 11A, and provide electromagnetic shielding from multiple directions, thereby providing a good shielding effect.

Alternatively, the shielding shell 12 may further include two fixing portions 123, wherein one fixing portion 123 is connected to the two second shielding portions 122 and the one first shielding portion 121, and the other fixing portion 123 is connected to the two second shielding portions 122 and the other first shielding portion 121.

The fixing portion 123 can function as a fixing connection, so that the shielding shell 12 is firmly fixed on the female housing body 11.

Some optional features of the groove 120 are described in detail below:

as a first structural feature, the plurality of grooves 120 may include a plurality of first grooves 120A.

As shown in fig. 1, a plurality of first grooves 120A are located on the outer surface of the first shield part 121 and the outer surface of the second shield part 122.

Alternatively, the first groove 120A may be a strip groove.

For example, when the shield shell 12 is machined, the plurality of grooves 120 may be machined in a thin metal plate, the thin metal plate with the plurality of grooves 120 may be cut into a predetermined shape, and the cut thin metal plate may be bent to obtain the shield shell 12 with the plurality of grooves 120 on the surface.

Second, the plurality of grooves 120 may include a plurality of second grooves 120B.

As shown in fig. 1, the plurality of second grooves 120B are located on an outer surface of the fixing portion 123.

Alternatively, the second groove 120B may be a strip groove.

Optionally, the plurality of second grooves 120B correspond to a portion of the first grooves 120A one-to-one, one end of each second groove 120B is connected to one end of the corresponding first groove 120A, and the other end of each second groove 120B is located at an edge of the fixing portion 123.

Therefore, the first groove 120A and the second groove 120B can be processed in one-time cutting and laser engraving processes, and the processing efficiency of the groove 120 is improved.

The third structural feature is that the plurality of first grooves 120A located in the first shielding part 121 are distributed at intervals along the second direction, and the plurality of first grooves 120A located in the second shielding part 122 are distributed at intervals along the first direction. Wherein the first direction is perpendicular to the second direction.

Alternatively, the plurality of first grooves 120A may be parallel to each other.

The plurality of first grooves 120A are parallel to each other, so that the plurality of first grooves 120A can be conveniently machined at one time, for example, by cutting, laser engraving and the like. In addition, the parallel positional relationship between the first grooves 120A can conveniently control the positional relationship between the plurality of tools, so that the plurality of first grooves 120A can be simultaneously processed in one cutting and engraving process.

The structure is characterized in that the extending direction of the first grooves 120A of the first shielding part 121 is perpendicular to the second direction, and the extending direction of the first grooves 120A of the second shielding part 122 is perpendicular to the first direction.

The manufacturing process of the shielding shell 12 with the plurality of grooves 120 on the surface is as follows: when the shielding case 12 is processed, the groove 120 may be processed on the thin metal plate, and then the thin metal plate having the groove 120 may be bent. When the metal thin plate having the groove 120 is bent, stress concentration is easily generated at the groove bottom of the groove 120, which causes the metal thin plate to be bent. When the extending direction of the first grooves 120A of the first shielding part 121 is perpendicular to the second direction and the extending direction of the first grooves 120A of the second shielding part 122 is perpendicular to the first direction, the stress at the groove bottom of the groove 120 is small, and the metal sheet is not easy to break.

The fifth structural feature is that the distances between the adjacent grooves 120 may be equal.

As shown in fig. 1, the surface of the shielding shell 12 has a plurality of grooves 120, a certain distance exists between every two adjacent grooves 120, and the distance between every two adjacent grooves 120 may be equal.

The distance between every two adjacent grooves 120 is equal, so that the shielding effect at each position of the shielding shell 12 can be more balanced. And the equal-interval distribution is easy to process, the processing efficiency is improved, and the processing cost is reduced.

In a sixth structural feature, the distance between two adjacent first grooves 120A located at different positions of the second shielding part 122 may be different.

As shown in fig. 2, among the plurality of first grooves 120A of the second shielding part 122, in the first direction, the interval between adjacent first grooves 120A near both sides is greater than the interval between adjacent first grooves 120A near the middle.

In the connector, the female socket terminal 112 is used for soldering with a circuit board to realize transmission of signals. And the second shielding portion 122 is a part of the shield case 12 opposite to the female socket terminal 112, and the female socket terminal 112 is opposite to the middle portion of the second shielding portion 122. Therefore, the second shielding part 122 is closer to the female socket terminal 112 than the first shielding part 121. Further, the middle portion of the second shielding portion 122 is the portion of the shielding shell 12 closest to the female socket terminal 112, so the middle portion of the second shielding portion 122 is more important for electromagnetic shielding. Therefore, the distance between the adjacent first grooves 120A at the middle portion of the second shielding portion 122 can be set smaller to improve the electromagnetic shielding effect of the second region 13N of the shielding shell 12.

Meanwhile, since the portions of the second shielding part 122 near both sides do not face the female socket terminal 112, the distance between the second shielding part and the female socket terminal 112 is relatively long. Therefore, the distance between adjacent first grooves 120A in these regions is reduced, and the electromagnetic shielding effect of the shield shell 12 on the female socket terminal 112 is not significantly enhanced. If all the first grooves 120A of the surface of the second shield part 122 are densely arranged, the strength of the shield case 12 may be excessively low. Therefore, the distance between the adjacent first grooves 120A near both sides in the second shielding part 122 can be set large to secure the overall strength of the shield case 12.

Alternatively, as shown in fig. 1, the spacing between adjacent first grooves 120A of the first shielding part 121 may be the same as the spacing between adjacent first grooves 120A of the second shielding part 122 on both sides thereof.

Since the first shielding part 121 is distant from the female socket terminal 112, the distance between adjacent first grooves 120A in the first shielding part 121 can be set to be large to ensure the overall strength of the shield shell 12.

With a seventh structural feature, as shown in fig. 11, the first grooves 120A may be all V-shaped grooves. That is, the cross section is taken perpendicular to the extending direction of the first grooves 120A, and the cross section of each first groove 120A is triangular.

Since the plurality of first grooves 120A may be machined by cutting, when a cutting tool is selected, the cross-section of the groove is triangular, which is different from a cutting tool having a cross-section of a groove with an arc shape or a rectangular shape. The cutting tool with grooves having triangular cross-sections has a sharp structure. Therefore, the grooves with triangular cross sections are easier to cut than the grooves with arc or rectangular cross sections, and the cutting depth of the grooves is easier to control, which is beneficial to the processing and forming of the first grooves 120A.

Alternatively, the cross-section of the plurality of first grooves 120A may be an isosceles triangle. Wherein the cross section is a plane sectioned perpendicular to the extending direction of the first groove 120A.

When the cross sections of the first grooves 120A are isosceles triangles, it is easy to see that the areas of two adjacent groove walls in each of the first grooves 120A are the same. In the terminal device, since the direction in which the electromagnetic wave outside the connector is incident on the shielding case 12 is arbitrary, the areas of the two groove walls of the plurality of first grooves 120A are set to be the same, and it can be ensured that the shielding effect of the shielding case 12 on different directions is closer.

Alternatively, the cross section of the first grooves 120A may be non-isosceles triangles.

When the cross-section of the first grooves 120A is not an isosceles triangle, it can be easily seen that the areas of two adjacent groove walls in each of the first grooves 120A are different. For convenience of description, the groove wall corresponding to the longer side of the non-isosceles triangle is referred to as a first groove wall, the groove wall corresponding to the shorter side of the non-isosceles triangle is referred to as a second groove wall, and the area of the first groove wall is larger than that of the second groove wall. In this case, a technician can adjust the areas of the first slot wall and the second slot wall and the included angle between the two slot walls according to actual needs, so that the shielding shell 12 has a better shielding effect on a certain specific direction.

As a structural feature eight, the roughness of the walls of the first plurality of grooves 120A may be in the range of 5 microns to 15 microns.

The groove walls of the plurality of first grooves 120A are provided with a roughness set in the range of 5 micrometers to 15 micrometers, which corresponds to the fact that the groove wall surfaces actually have many minute surface elements oriented differently, and the total area of these surface elements is also larger than the area of the smooth surface. Thus, the shielding shell 12 has a relatively balanced shielding effect on electromagnetic waves in all directions, and the total shielding effect is relatively good.

The above optional features of the plurality of first recesses 120A on the surface of the shield case 12 may be used alone or in combination with a plurality of features.

With the shield case 12 of the present application, since the surface of the shield case 12 has the plurality of first grooves 120A. For the smooth shielding shell 12 of surface, the shielding shell 12 with a plurality of first grooves 120A on the surface can well shield the electromagnetic waves in a plurality of directions, and then improve the electromagnetic shielding effect.

The embodiment of the present application provides a female connector housing 1, as shown in fig. 3 (fig. 3 is an assembly view), the female connector housing 1 includes a housing body 11 and a shielding shell 12. In the female socket body 11, a female socket base 111 and a female socket terminal 112 may be included. As shown in fig. 4 and 5, the female housing base 111 has a first surface 11M and a second surface 11N opposite to each other, and the first surface 11M has a mating groove 11A. As shown in fig. 6, the female socket terminal 112 may include a connection portion 112A and a soldering portion 112B. The shield case 12 surrounds the insertion groove 11A, and the surface of the shield case 12 has a plurality of grooves 120.

Hereinafter, each part of the female connector housing 1 will be described in detail:

As shown in fig. 3, the female socket body 11 may include a female socket base 111 and female socket terminals 112.

(1) Female seat base 111

The female housing base 111 is a member for guiding the female housing 1 and the male header 2 to complete the connection. As shown in fig. 4, the female socket body 11 has a first surface 11M. As shown in fig. 5, the female seat base 111 further has a second surface 11N. And a first surface 11M and a second surface 11N. As shown in fig. 4, the first surface 11M of the female housing base 111 may have a socket 11A, and the socket 11A may receive the male connector 2. The shape of the insertion groove 11A matches the shape of the male connector 2, and may be, for example, a rectangular parallelepiped, a cylindrical shape, or the like. In the process that the male connector 2 is connected to the female base 1, the side wall of the insertion groove 11A provides positioning guide for the male connector 2, so that the male connector 2 can be smoothly inserted into the insertion groove 11A. In addition, after male connector 2 is installed to female seat 1, inserting groove 11A can play spacing effect, prevents that male connector 2 from taking place to remove in inserting groove 11A's length direction and width direction.

The female socket base 111 is also a member for fixedly connecting the female socket terminal 112 and the shield case 12. As shown in fig. 5, there may be a plurality of through holes 11T between the second surface 11N of the female socket base 111 and the groove bottom of the insertion groove 11A, and the position of each through hole 11T may correspond to the mounting position of each female socket terminal 112. These through holes 11T can fixedly connect the connection portions 112A of the female socket terminals 112 in the insertion grooves 11A. A plurality of mounting grooves 11S may be respectively formed at an outer sidewall of the female socket base 111, positions and shapes of the mounting grooves 11S correspond to those of the shielding shell 12, and the mounting grooves 11S may be used to fixedly mount the shielding shell 12, so that the shielding shell 12 surrounds the insertion groove 11A, and further surrounds the female socket terminal 112 located in the insertion groove 11A.

The material of the female base 111 can be various High Temperature resistant polymers, such as High Temperature Polyamides (HTPA). The machining method of the female housing base 111 may be injection molding or cutting molding.

(2) Female socket terminal 112

The female socket terminal 112 is a component of the female socket 1 for electrically connecting with the male connector to realize signal transmission. As shown in fig. 6, the female socket body 11 includes a plurality of female socket terminals 112 therein, each of the female socket terminals 112 has the same shape and size, and the arrangement may be arbitrarily set according to the requirement. The connection portion 112A of each female socket terminal 112 is located in the insertion groove 11A, and the soldering portion 112B is located on the second surface 11N of the female socket base 111 through the through hole 11T.

In the female housing shown in fig. 6, the female housing terminals 112 are distributed in two rows. The female socket terminals 112 in each row are the same number. The placement postures of the female socket terminals 112 in each row are the same, and the placement postures of the female socket terminals 112 between the two rows are mutually reversed in the horizontal plane.

The female socket terminal 112 includes a connection portion 112A and a soldering portion 112B, and the connection portion 112A and the soldering portion 112B are integrally formed. The soldering portion 112B of the female socket terminal 112 is soldered to the circuit board. The connecting portion 112A of the female socket terminal 112 is fastened with the terminal of the male connector 2, so that the female socket 1 is connected with the male connector 2, and signal transmission is further realized.

The female socket terminal 112 can be made of various metals with good conductivity, such as copper.

The connection mode of the female socket terminal 112 and the female socket base 111 can be clamping, insert molding, gluing, and the like.

Second, the shielding case 12

The shield shell 12 is a member for electromagnetic shielding in the female housing 1. Signals transmitted in the connector are easily interfered by electromagnetic waves and can generate electromagnetic waves to interfere other components, and particularly, radio frequency signals transmitted in the connector are easily interfered or externally interfered. The shielding shell 12 utilizes the property of metallic material capable of reflecting electromagnetic waves to form a barrier around the female socket terminal 112, so as to prevent external electromagnetic waves from entering the shielding shell 12, thereby implementing electromagnetic shielding.

The shielding shell 12 may surround the insertion groove 11A and be connected to the female housing body 11.

As shown in fig. 3 and 6, the shield case 12 may be mounted on the outer surface of the female socket base 111 after the female socket base 111 is injection molded.

Or the shielding shell 12 may be formed by machining, and then the formed shielding shell 12 is fixed at a corresponding position in the injection mold of the female base 111, and is processed by insert molding.

In the present example, the shield shell 12 is mounted on the outer surface of the female socket base 111, and in other examples, the shield shell 12 may also be at least partially embedded inside the female socket base 111, so that the connection between the shield shell 12 and the female socket body 11 is tighter.

Alternatively, the shielding shell 12 may include two first shielding portions 121 and two second shielding portions 122, the two first shielding portions 121 are oppositely disposed and located at two opposite sides of the female socket body 11 in the first direction of the inserting slot 11A, the two second shielding portions 122 are oppositely disposed and located at the other two opposite sides of the female socket body 11 in the second direction of the inserting slot 11A, and each second shielding portion 122 is respectively connected to the two first shielding portions 121. The first direction and the second direction are both perpendicular to the plugging direction corresponding to the plugging groove 11A, and the first direction is perpendicular to the second direction.

The shielding shell 12 may further include two fixing portions 123, where the two fixing portions 123 are located on the first surface 11M and located on two opposite sides in the first direction, one of the fixing portions 123 is connected to the two second shielding portions 122 and the one first shielding portion 121, and the other fixing portion 123 is connected to the two second shielding portions 122 and the other first shielding portion 121.

The surface of the shield shell 12 remote from the female socket body 11 may have a plurality of grooves 120. Since the shielding case 12 realizes electromagnetic shielding by using the property that the metal material can reflect electromagnetic waves, the metal material with a smooth surface can only have a good shielding effect on electromagnetic waves in the direction perpendicular to the surface. Therefore, the existence of the groove 120 enables the shielding case 12 to well shield external electromagnetic waves in multiple directions, and further enhances the electromagnetic shielding effect of the shielding case 12.

Alternatively, the surface of the shield shell 12 adjacent to the female socket body 11 may also have a plurality of grooves 120.

In this example, the plurality of grooves 120 are provided on the surface of the shielding shell 12 close to the female socket body 11, so that the electromagnetic shielding effect of the shielding shell 12 on the electromagnetic waves radiated by the female socket terminal 112 can be improved, the electromagnetic waves radiated by the female socket terminal 112 can be prevented from affecting other components except the connector, and the grooves 120 can also form a fit with the surface of the female socket body 11, so that the female socket body 11 is partially embedded into the grooves 120, and the shielding shell 12 is more tightly connected with the female socket body 11.

Some optional features of the groove 120 are described in detail below:

As shown in fig. 6, the plurality of first grooves 120A are located on a surface of the first shield part 121 remote from the female housing body 11 and a surface of the second shield part 122 remote from the female housing body 11.

Alternatively, the first groove 120A may be a strip groove.

As shown in fig. 6, the plurality of second grooves 120B are located on the surface of the fixing portion 123 away from the female socket body 11.

Alternatively, the second groove 120B may be a strip groove.

Optionally, the plurality of second grooves 120B may correspond to a portion of the first grooves 120A one-to-one, one end of each second groove 120B is connected to one end of the corresponding first groove 120A, and the other end of each second groove 120B is located at an edge of the fixing portion 123 close to the inserting slot 11A.

The third structural feature is that the plurality of first grooves 120A located in the first shielding part 121 are distributed at intervals along the second direction, and the plurality of first grooves 120A located in the second shielding part 122 are distributed at intervals along the first direction.

As shown in fig. 7 and 8 (fig. 7 and 8 are side views of different sides), the surface of the shielding shell 12 has a plurality of grooves 120, a certain distance exists between every two adjacent grooves 120, and the distance between every two adjacent grooves 120 may be equal.

As shown in fig. 9, of the plurality of first grooves 120A of the second shielding part 122, in the first direction, the interval between adjacent first grooves 120A near both sides is greater than the interval between adjacent first grooves 120A near the middle.

In the connector, the female socket terminal 112 is used for soldering with a circuit board to realize transmission of signals. And the second shielding portion 122 is a part of the shield case 12 opposite to the female socket terminal 112, and the female socket terminal 112 is opposite to the middle portion of the second shielding portion 122. Therefore, the second shielding part 122 is closer to the female socket terminal 112 than the first shielding part 121. Further, the middle portion of the second shielding portion 122 is the portion of the shielding shell 12 closest to the female socket terminal 112, so the middle portion of the second shielding portion 122 is more important for electromagnetic shielding. Therefore, the distance between the adjacent first grooves 120A at the middle of the second shielding part 122 can be set smaller to improve the electromagnetic shielding effect of the second region 13N of the shielding shell 12.

Meanwhile, since the portions of the second shielding part 122 near both sides do not face the female socket terminal 112, the distance between the second shielding part and the female socket terminal 112 is relatively long. Therefore, the distance between adjacent first grooves 120A in these regions is reduced, and the electromagnetic shielding effect of the shield shell 12 on the female socket terminal 112 is not significantly enhanced. If all the first grooves 120A of the surface of the second shield part 122 are densely arranged, the strength of the shield case 12 may be excessively low. Therefore, the distance between the adjacent first grooves 120A near both sides in the second shield portion 122 can be set large to secure the entire strength of the shield case 12.

Alternatively, as shown in fig. 9 and 10 (fig. 9 and 10 are side views of different sides), the pitch of the adjacent first grooves 120A located at the first shielding part 121 may be the same as the pitch of the adjacent first grooves 120A located at the second shielding part 122 near both sides.

As shown in fig. 11, the first grooves 120A may be V-shaped grooves. That is, the cross section is taken perpendicular to the extending direction of the first grooves 120A, and the cross section of each first groove 120A is triangular.

Since the plurality of first grooves 120A may adopt a cutting processing method, when a cutting tool is selected, the cross section of the groove is triangular, and the cutting tool is different from a cutting tool having a groove with an arc-shaped or rectangular cross section. The cutting tool with grooves having triangular cross-sections has a sharp structure. Therefore, the grooves with triangular cross sections are easier to cut than the grooves with arc or rectangular cross sections, and the cutting depth of the grooves is easier to control, which is beneficial to the processing and forming of the first grooves 120A.

Alternatively, the cross section of the plurality of first grooves 120A may be an isosceles triangle. Wherein the cross section is a plane sectioned perpendicular to the extending direction of the first groove 120A.

When the cross-sections of the first grooves 120A are not isosceles triangles, it is easy to see that the areas of two adjacent groove walls in each of the first grooves 120A are different. For convenience of description, the groove wall corresponding to the longer side of the non-isosceles triangle is referred to as a first groove wall, the groove wall corresponding to the shorter side of the non-isosceles triangle is referred to as a second groove wall, and the area of the first groove wall is larger than that of the second groove wall. In this case, a technician can adjust the areas of the first slot wall and the second slot wall and the included angle between the two slot walls according to actual needs, so that the shielding shell 12 has a better shielding effect on a certain specific direction.

As a structural feature eight, the roughness of the walls of the first plurality of grooves 120A may be in the range of 5-15 microns.

The groove walls of the plurality of first grooves 120A are provided with a roughness set in the range of 5 micrometers to 15 micrometers, which corresponds to the fact that the groove wall surfaces actually have many minute surface elements oriented differently, and the total area of these surface elements is also larger than the area of the smooth surface. Thus, the shielding shell 12 has a balanced shielding effect on electromagnetic waves in all directions, and the total shielding effect is good.

With the female connector housing 1 of the present application, since the surface of the shield shell 12 in the female housing 1 has the plurality of first grooves 120A. For the smooth shielding shell 12 of surface, the shielding shell 12 with a plurality of first grooves 120A on the surface can well shield the electromagnetic waves in a plurality of directions, and then improve the electromagnetic shielding effect.

The embodiment of the application also provides a connector, which comprises a male head 2 and the female seat 1 described in the embodiment.

As shown in fig. 3 and 12, one end of the female housing body 11 has an insertion groove 11A, the shape and size of the insertion groove 11A correspond to those of the male connector 2, and the male connector 2 is inserted into the insertion groove 11A of the female housing 1.

Since the male plug 2 is inserted into the insertion groove 11A of the female socket 1, the shielding shell 12 surrounds the side wall of the female socket body 11 and the male plug 2 inside the shielding shell 12, so that the shielding shell 12 can play a role of electromagnetic shielding for the whole connector. Furthermore, the surface of the shielding shell 12 has a plurality of grooves 120, which can shield electromagnetic waves from a plurality of directions, so that the shielding shell 12 can protect the entire connector better.

In addition, because the shape and the size of the inserting groove 11A correspond to those of the male head 2, after the male head 2 is inserted into the inserting groove 11A of the female seat 1, the male head 2 can be limited in a plane perpendicular to the inserting direction, the male head 2 is prevented from moving in the plane perpendicular to the inserting direction, and then the female seat 1 and the male head 2 are firmly connected.

The embodiment of the application further provides a terminal device, the connector is installed on the terminal device, and the terminal device can be a mobile phone, a tablet computer and the like. Female seat terminal 112 in the female seat 1 of connector welds with the PCB, and public first terminal in public head 2 welds with FPC, and then realizes being connected between FPC and the PCB. This scheme of adoption can guarantee that the connector has good shielding effect, and then, when guaranteeing that terminal equipment is inside to carry out signal transmission, signal transmission's stability and reliability guarantee that terminal equipment normally works.

The above description is only exemplary of the present application and should not be taken as limiting, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
