[0002] With the continuous development of data transmission technology, the demand for high-frequency transmission is getting higher and higher. Traditional connectors generally include an insulating body, terminals and grounding plates. The terminals are assembled by arranging grounding terminals and signal terminals at intervals. When this type of connector is short-circuited at high frequency, electromagnetic interference will be generated between the signal terminals, resulting in high-frequency electric field leakage, reflection and other problems, affecting the high-frequency transmission of data. In order to improve the high-frequency performance of the connector, the current solution is to install a metal shielding part on the insulating body, and shield the interference signal by conducting the shielding part with the grounding terminal to improve the high-frequency performance of the connector. However, the existing shielding parts are directly in contact with the grounding terminal for conduction. The resistance value of the conduction circuit between the shielding part and the grounding terminal is a fixed value, which can only be used in circuits with one high-frequency performance.

[0046] Embodiment: A connector with adjustable high-frequency performance includes an insulating body 11, a terminal 122 and a shielding member 13 made of a metal material, the insulating body 11 is provided with two rows of terminal receiving grooves 113 arranged in parallel and spaced apart, a number of terminals 122 are respectively arranged in the terminal receiving grooves 113 of the insulating body 11, the shielding member 13 made of a conductive material is fixedly installed on the surface of the insulating body 11, a number of metal cantilever structures 1311 are integrally formed on the shielding member 13, the metal cantilever structures 1311 can extend into the terminal receiving grooves 113, and a conductive block 1312 made of a non-metallic conductive material is also provided, the conductive block 1312 is tightly clamped between the metal cantilever structure 1311 and the grounding terminal surface in the terminal 122 to make the shielding member 13 conductive with the grounding terminal.

[0047] The metal cantilever structure 1311 of the shielding part 13 of the connector is electrically connected to the ground terminal in the terminal 122 through a conductive block 1312 made of non-metallic conductive material to form a conductive structure. When selecting a connector, different non-metallic conductive materials are selected to make the conductive block 1312 according to different high-frequency performance requirements of the connector in the circuit, thereby changing the electronic conduction resistance between the shielding part 13 and the ground, and then changing the shielding strength of the shielding part 13, thereby realizing a change in the high-frequency performance of the connector, and thus being suitable for circuits with different high-frequency requirements.

[0048] The shielding member 13 is fixedly mounted on two opposite side walls of the insulating body 11 perpendicular to the extension direction of the terminal 122. The side walls of the insulating body 11 are provided with avoidance opening grooves 118 corresponding one-to-one to the grounding terminals in the terminals 122. The contact portion of the shielding member 13 passes through the avoidance opening grooves 118 and is electrically contacted and conducted with each grounding terminal one-to-one through non-metallic conductive material. The shielding member 13 is assembled at different positions of the insulating body 11 to adapt to different connector design requirements. When the shielding member 13 is assembled on the two side walls of the insulating body 11 perpendicular to the extension direction of the terminal 122, the contact portion of the shielding member 13 needs to pass through the avoidance opening groove 118 on the side wall of the insulating body 11 and enter the terminal receiving groove 113, and finally conduct electricity with each grounding terminal through the non-metallic conductive material. When the shielding member 13 is assembled with the insulating body 11, a concave shielding member receiving groove 111 can be formed on the insulating side wall to accommodate the shielding member 13, so that the shielding member 13 remains flush with the surface of the insulating body 11 after assembly, avoiding increasing the thickness or height of the connector. At the same time, a number of shielding member retaining columns 112 arranged at intervals are provided on the bottom surface of the shielding member receiving groove 111. , a plurality of shielding member holding holes 133 are provided on the shielding member 13, and the shielding member holding holes 133 can be of various shapes, preferably a special-shaped hole with an uneven inner wall, and the shielding member holding column 112 is passed through the shielding member holding hole 133, and the two are fixedly connected to form a whole by interference or hot melting. It is also best to provide shielding member holding grooves 117 at both ends of the bottom surface of the shielding member receiving groove 111 of the insulating body 11, and shielding member holding portions 132 are formed at both ends or in the middle of the shielding member 13 by bending. The side walls of the shielding member holding portion 132 are preferably a concave and convex structure, and the shielding member holding portion 132 is fixedly clamped in the shielding member holding groove 117 of the insulating body 11 through the interference structure, so as to realize the fixed connection between the two ends of the shielding member 13 and the insulating body 11.

[0049] The shielding member 13 is fixedly covered on the outside of the opening of the terminal receiving groove 113 of the insulating body 11. The side wall of the terminal receiving groove 113 of the insulating body 11 is provided with an avoidance opening groove 118 which corresponds one-to-one to the contact portion on the shielding member 13. The contact portion of the shielding member 13 is inserted into the avoidance opening groove 118 on the side wall of the terminal receiving groove 113 and is electrically contacted and connected with each grounding terminal one-to-one through non-metallic conductive material. The shielding member 13 is assembled at different positions of the insulating body 11 to adapt to different connector design requirements. When the shielding member 13 is assembled on the end face of the insulating body 11 provided with the terminal receiving groove 113, a shielding member holding groove 117 is provided on the end face of the insulating body 11 provided with the terminal receiving groove 113, and a shielding member holding portion 132 is formed by bending at both ends or in the middle of the shielding member 13. The shielding member holding portion 132 is fixedly clamped in the shielding member holding groove 117 of the insulating body 11 through an interference structure. At the same time, a number of shielding member holding columns 112 are arranged at intervals on the end face of the insulating body 11 provided with the terminal receiving groove 113, and a plurality of shielding member holding holes 133 are provided on the shielding member 13. The shielding member holding columns 112 are passed through the shielding member holding holes 133, and the two are fixedly connected to form a whole by interference or hot melting.

[0050] The conductive block 1312 is a non-metallic conductive adhesive injected into the avoidance opening 118 of the insulating body 11 by a glue injection device. The non-metallic conductive adhesive is fixedly attached to the surface of the ground terminal, and the metal cantilever structure 1311 on the shield 13 is inserted into the non-metallic conductive adhesive. After the terminal 122 is assembled into the insulating body 11, liquid non-metallic conductive adhesive is injected into the avoidance opening 118 of the insulating body 11 by a glue dispensing device, so that the liquid non-metallic conductive adhesive adheres to the ground terminal. The shield 13 is then assembled, and the metal cantilever structure 1311 on the shield 13 is inserted into the liquid conductive adhesive. After baking at a certain temperature, the liquid non-metallic conductive adhesive solidifies on the ground terminal. The metal cantilever structure 1311 of the shield 13 and the ground terminal are then electrically connected to each other through the non-metallic conductive adhesive. By adjusting the composition of the non-metallic conductive adhesive, its conductive properties are changed, thereby adjusting the contact resistance.

[0051] Conductive block 1312 is a non-metallic conductive coating, which is attached to the surface of the metal cantilever structure 1311 of the shield 13 or the sidewall surface of the ground terminal. The non-metallic conductive coating is applied to a designated area of ​​the metal raw material of the shield 13 through a silk screen process, followed by stamping. After forming, the metal cantilever structure 1311 of the shield 13 has a layer of conductive coating on its surface. After the shield 13 is assembled on the insulating body 11, the metal cantilever structure 1311 on the shield 13 and the ground terminal are electrically connected through the non-metallic conductive coating, thereby adjusting the contact resistance. The non-metallic conductive coating can also be applied to a designated area of ​​the ground terminal (after stamping and electroplating) through a silk screen process. By replacing non-metallic conductive coating materials with different conductive properties, the resistance between the shield 13 and the ground terminal can be changed, thereby changing the high-frequency performance of the connector.

[0052] The conductive block 1312 is a non-metallic adhesive sheet-like conductor, which is bonded to the surface of the metal cantilever structure 1311 of the shielding component 13 or to the side wall surface of the ground terminal. The non-metallic adhesive sheet conductor is cut into a shape and size corresponding to the contact end of the metal cantilever structure 1311 of the grounding terminal through a die-cutting process, and is attached to the metal cantilever structure 1311 of the corresponding grounding terminal through a patch device. The non-metallic adhesive sheet conductor can also be attached to the surface of the connecting part of the grounding terminal. When the best grounding terminal is formed, a contact groove is formed on its contact part, and the non-metallic adhesive sheet conductor is attached to the contact groove of the grounding terminal, and then the shielding part 13 is assembled. The metal cantilever structure 1311 on the shielding part 13 and the grounding terminal are connected to each other through the non-metallic adhesive sheet conductor. It is only necessary to replace the non-metallic adhesive sheet conductor with different conductive properties as needed to adjust the contact resistance. The non-metallic adhesive sheet conductor can also be attached to the specified area of ​​the metal cantilever structure 1311 or the specified area of ​​the grounding terminal on the shielding part 13 through a silk screen printing process.

[0053] The conductive block 1312 can be stably clamped between the metal cantilever structure 1311 of the shielding part 13 and the grounding terminal through the above-mentioned different methods. In addition, other structures can also be used, as long as a non-metallic conductive object can be formed between the metal cantilever structure 1311 of the shielding part 13 and the grounding terminal. This type of equivalent replacement can be easily thought of by those skilled in the art based on the technical solution of this patent and falls within the scope of protection of this patent.

[0054] The metal cantilever structure 1311 is a cantilever structure formed by a bending process and can be elastically deformed along the width direction of the shielding member 13. The end of the metal cantilever structure 1311 is bent to form a contact surface parallel to the surface of the grounding terminal, and the conductive block 1312 is tightly clamped between the contact surface at the end of the metal cantilever structure 1311 and the surface of the grounding terminal.

[0055] The metal cantilever structure 1311 is a cantilever structure formed by punching and bending along the width direction of the shielding part 13, which can be elastically deformed along the length direction of the shielding part 13. The metal cantilever structure 1311 has a protrusion formed on the side wall along its deformation direction, and the protrusion can tightly contact the side wall surface of the grounding terminal. During molding, a metal cantilever structure 1311 and a convex point shape are formed on the shielding member 13 material strip through a punching process, and then the metal cantilever structure 1311 is made perpendicular to the shielding member 13 by bending. After the shielding member 13 is fixedly installed on the surface of the insulating body 11, the metal cantilever structure 1311 extends into the terminal receiving groove 113 through the avoidance opening groove 118 on the side wall of the insulating body 11, and the convex points on the side wall of the metal cantilever structure 1311 elastically press against the side wall in the thickness direction of the grounding terminal. This type of metal cantilever structure 1311 is preferably arranged on both sides of the width direction of the shielding member 13, and two metal cantilever structures 1311 adjacent to each other along the length direction of the shielding member 13 form a group, and the convex points on the side walls of each group of metal cantilever structures 1311 are arranged opposite each other, and each group of metal cantilever structures 1311 is clamped on the two side wall surfaces in the thickness direction of the same grounding terminal through the conductive block 1312, so that the two sides of the grounding terminal can be tightly clamped and formed. Two contact points are formed to avoid poor contact. In order to make the connection strength between the shielding part 13 and the insulating body 11 higher, the metal cantilever structure 1311 is in more stable contact with the grounding terminal. It is best to form a number of limiting arms 134 of the vertical shielding part 13 on the side wall of the shielding part 13 by punching and bending, and the end of the limiting arm is formed with an avoidance groove structure 1341. A limiting opening groove is provided on the side wall of the terminal receiving groove 113 of the insulating body 11 for accommodating the signal terminal 122. The limiting arms are inserted into the limiting opening groove one by one. The signal terminal 122 in the terminal receiving groove 113 is accommodated in the avoidance groove structure at the end of the limiting arm, and there is a set gap between the side wall of the signal terminal 122 and the inner side wall of the avoidance groove structure. This structure can fully utilize the space between the shielding part 13 and the insulating body 11 without affecting the signal terminal 122, so that the shielding part 13 is more firmly combined with the insulating body 11 and the position is more accurate.

[0056] The end of each metal cantilever structure 1311 forms at least two contact points through a bifurcated structure, and the two contact points are respectively connected to different parts of the same ground terminal. For the cantilever structure that is formed by the bending process and can be elastically deformed along the width direction of the shielding part 13, the two side walls in the width direction of the shielding part 13 are bent toward the middle direction of the shielding part 13 to form a forked metal cantilever structure 1311. The forked structure of the metal cantilever structure 1311 can be set in a symmetrical state or an asymmetrical state, and each forked end is tightly contacted with different parts of one side of the grounding terminal through the conductive block 1312. For the cantilever structure that is formed by punching and bending along the width direction of the shielding part 13 and can be elastically deformed along the length direction of the shielding part 13, a two-forked structure with relatively opposite protrusions is formed during punching, which respectively clamps the conductive blocks 1312 on the two side wall surfaces in the thickness direction of the grounding terminal, and is connected to two different parts of the same grounding terminal connection part through the forked parts on the metal cantilever structure 1311. This structure enables the metal cantilever structure 1311 to contact two spaced parts of the same grounding terminal respectively, thereby preventing poor contact.

[0057] A concave shielding member receiving groove 111 is formed on the surface of the insulating body 11, and the shielding member 13 can be accommodated in the shielding member receiving groove 111 on the side wall of the insulating body 11, and the outer surface of the shielding member 13 is flush with the outer surface of the insulating body 11. At least one shielding member holding column 112 and at least one shielding member holding groove 117 are provided on the bottom surface of the shielding member receiving groove 111, and at least one shielding member holding hole 133 and at least one shielding member holding portion 132 are provided on the shielding member 13. The shielding member holding columns 112 are respectively inserted into the shielding member holding holes 133, and the shielding member holding columns 112 and the shielding member holding holes 133 are fixedly connected to form a whole by interference or hot melting. A concave and convex bite structure is formed on the side wall of the shielding member holding portion 132, and the shielding member holding portion 132 is inserted into the shielding member holding groove 117. The bite structure on the side wall of the shielding member holding portion 132 is interfered and fixedly engaged with the side wall of the shielding member holding groove 117. When the shielding member 13 is assembled with the insulating body 11, the shielding member receiving groove 111 can accommodate the shielding member 13, so that the shielding member 13 remains flush with the surface of the insulating body 11 after assembly, thereby avoiding increasing the thickness or height of the connector. The shielding member holding hole 133 is preferably a special-shaped hole with an uneven inner wall, and the side wall of the shielding member holding column 112 forms a bite structure with the surface of the shielding member holding hole 133. The shape of the shielding member holding hole 133 is not limited, such as a gourd hole, a wave hole, a polygonal hole, a star hole, etc., and can also be a round hole or Long strip holes, etc., as long as they can be plugged and fixed with the shielding member holding column 112; the shielding member holding portion 132 on the shielding member 13 is preferably formed integrally on the side wall of the shielding member 13 by bending, and there are preferably two or more shielding member holding portions 132, which are respectively located at the two ends and the middle in the length direction of the shielding member 13 to achieve a stable connection between the two ends of the shielding member 13 and the insulating body 11, while avoiding warping of the shielding member 13 on the insulating body 11, affecting the electrical contact between the elastic contact block and the grounding terminal.
