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

To facilitate understanding of the connector provided in the embodiments of the present application, an application scenario thereof will be described first. The connector can be applied to electronic equipment for transmitting high-speed differential signals or single-ended signals and transmitting large current, wherein the electronic equipment can be communication equipment, servers, supercomputers or equipment such as routers and switches in the prior art. With the continuous improvement of communication technology, the requirements on data transmission rate and transmission quality are higher and higher, so that the crosstalk between signals is required to be further reduced.

The connector provided by the embodiment of the application comprises a terminal module, a shell and a plurality of conductive pieces, wherein the terminal module is used for realizing signal transmission, and the shell and the conductive pieces are used for realizing isolation between signals. Referring to fig. 1, the terminal module 10 includes terminal modules 11, and when the terminal modules 11 are specifically arranged, the number of the terminal modules 11 may be one or two, and when the number of the terminal modules 11 is two, the two terminal modules 11 may be arranged in a stack in a first direction (i.e., an x direction). The terminal module 11 includes a plurality of insulators 12, the insulators 12 extend along a second direction (i.e., a y direction), and signal terminals 13 for transmitting signals are disposed at intervals among the insulators 12 and are wrapped in the insulators 12. The insulator 12 may be an injection molded gel structure, and the insulators 12 of the terminal module 11 may be integrally formed to simplify the manufacturing process of the terminal module 11, in which case, the insulators 12 may be interconnected by an intermediate gel 14 as shown in fig. 2. When two terminal modules 11 are stacked, the insulators 12 of the two terminal modules 11 are positioned opposite to each other. Further, in the second direction, both ends of the signal terminals 13 respectively project beyond the end portions of the insulator 12 to enable connection with a circuit board and other connectors. Specifically, the signal terminal 13 has a fisheye pin 15 at one end for electrical connection with a circuit board and an elastic arm 16 at the other end for electrical connection with another connector.

In the embodiment of the present invention, the signal terminals 13 in the insulator 12 may be single-ended signal terminals or differential signal terminals arranged in pairs, and therefore, the connector provided in the embodiment of the present invention may implement shielding of single-ended signals as well as shielding of differential signals.

When the housing is disposed, please refer to fig. 1 and fig. 2, the housing 20 includes a first housing 21 and a second housing 22, wherein the first housing 21 is disposed on one side of the terminal module 10 along a first direction (i.e., an x direction), and the second housing 22 is disposed on the other side of the terminal module 10 along the first direction, so as to clamp the terminal module 10 between the first housing 21 and the second housing 22.

As shown in fig. 2, the conductive member 30 also extends along the second direction, and the conductive members 30 are alternately arranged with the insulators 12 of the terminal module 11, that is, one conductive member 30 is arranged between every two adjacent insulators 12, so as to separate the two adjacent insulators 12, of course, for the outermost insulator 12, the conductive member 30 can also be arranged on the side of the insulator 12 away from the other insulator 12, so as to further improve the shielding effect. In the first direction, the conductive member 30 includes a first side 31 and a second side 32, wherein the first side 31 is in conductive contact with the first housing 21 to form an electrical connection, and the second side 32 is in conductive contact with the second housing 22 to form an electrical connection.

When the terminal module 10 includes only one terminal module 11, as shown in fig. 1 and 2, in one embodiment of the present application, the conductive member 30 may be a ground terminal 33, and then, in the second direction, one end of the ground terminal 33 may be provided with a fisheye pin 15 for ground connection of a circuit board, and the other end may be provided with a spring arm 16 for ground connection of other connectors. Taking a pair of differential line numbers in each insulator as an example, and fig. 3 is a schematic diagram illustrating that the differential signal terminals are shielded according to this embodiment, it can be seen that, by electrically contacting the ground terminal 33 with the first housing 21 and the second housing 22 at two ends of the terminal module 10, a shielding effect of 360 degrees can be formed on the signal terminal 13 in each insulator 12, so that crosstalk between signals can be greatly reduced, and the transmission rate and transmission quality of data can be improved. In addition, in order to ensure the reliability of the electrical connection between the ground terminal 33 and the first and

second housings

21 and 22, two sides of the ground terminal 33 may be fixedly connected to the first and

second housings

21 and 22, respectively, and in particular, in the setting, the connection may be achieved by using a connection structural member, or the ground terminal 33 may be welded and fixed to the first and

second housings

In the above-described embodiment, in order to facilitate the conductive contact between the ground terminal 33 and the first and

second housings

21 and 22, the first and

second housings

For example, in the embodiment shown in fig. 1 and 2, the ground terminal 33 has a cross-section in a shape of a "zigzagging", in which case, for the first housing 21, a portion of the first housing 21 corresponding to the ground terminal 33 may protrude away from the ground terminal 33 to be in conductive contact with the first side 31 of the "zigzagging" ground terminal 33, and for the second housing 22, a portion of the second housing 22 corresponding to the ground terminal 33 may protrude toward the ground terminal 33 to be in conductive contact with the second side 32 of the "zigzagging" ground terminal 33. In this embodiment, when the first housing 21 and the second housing 22 are manufactured, the concave-convex structure design can be formed on the two housings by using a process such as stamping or metal injection molding, which is not particularly limited in this application.

When the terminal module 10 includes two terminal modules 11, referring to fig. 4, in the embodiment of the present application, the connector further includes a conductive plate 40, the conductive plate 40 is located between the two terminal modules 11, and includes a plurality of first sub-plates 41 and a plurality of second sub-plates 42 that are alternately arranged, where the first sub-plates 41 are portions of the conductive plate 40 opposite to the insulators 12 on both sides, and it can be understood that the second sub-plates 42 are portions of the conductive plate 40 that are staggered from the insulators 12 on both sides, and then the second sub-plates 42 can be formed as the conductive members 30 in the embodiment of the present application.

In the above embodiment, in order to facilitate the conductive contact between the conductive plate 40 and the first housing 21 and the second housing 22, referring to fig. 5, in an embodiment of the present application, the grooves 43 may be respectively formed on both sides of the first sub-plate 41, and the depth of the groove 43 should be not less than the thickness of the insulator 12, so that when the insulators 12 of the terminal modules 11 on both sides are respectively embedded in the corresponding grooves 43, the second sub-plate 42 can be flush with the surface of the insulator 12 and even exceed the insulator 12, so as to ensure that both sides of the second sub-plate 41 can be respectively contacted with the first housing 21 and the second housing 22.

In another embodiment of the present application, the first housing 21 and the second housing 22 may be designed to have a concave-convex structure, specifically, as shown in fig. 4 and fig. 6, a first avoiding protrusion 23 for avoiding the insulator 12 on one side is disposed at a position of the first housing 21 corresponding to the first sub-board 41, a second avoiding protrusion 24 for avoiding the insulator 12 on the other side is disposed at a position of the second housing 22 corresponding to the first sub-board 41, and the depths of the two avoiding protrusions are not less than the thickness of the insulator 12, so that when the insulators 12 of the terminal modules 11 on both sides are disposed in the corresponding avoiding protrusions, it can be ensured that both sides of the second sub-board 42 can be respectively contacted with the first housing 21 and the second housing 22. In this embodiment, when the first housing 21 and the second housing 22 are manufactured, the concave-convex structure design may be formed on the two housings by using a stamping process or a metal injection molding process.

It can be understood that, in other embodiments of the present application, on the basis that the grooves are formed on the two sides of the first sub-board, the concave-convex design can be performed on the first housing and the second housing at the same time, and at this time, it is only required to ensure that the sum of the depth of the groove and the depth of the avoiding protrusion is not less than the thickness of the insulator, and details are not described here.

In the embodiment of the present application, the conductive plate 40 may be made of conductive plastic, plated plastic, or conductive metal, which is not limited in the present application. In order to ensure reliability of electrical connection between the conductive plates 40 and the first and

second housings

21 and 22, the second sub-plates 42 of the conductive plates 40 may be fixedly connected to the first and

second housings

21 and 22, respectively. For example, when the conductive plate 40 is made of conductive adhesive or plated plastic, the second sub-plate 42 can be directly bonded to the first housing 21 and the second housing 22 through the conductive adhesive, so as to achieve electrical conduction; when the conductive plate 40 is made of metal, the second sub-plate 42 can be welded and fixed to the first housing 21 and the second housing 22 by laser welding, and electrical conduction can be achieved.

Similarly, for convenience of implementation, the embodiment of the present application may achieve a shielding effect by grounding the housing, specifically, as shown in fig. 5 and 7, along the second direction, one end of the portion of the first housing 21 corresponding to the second sub-board 42 is provided with a first pin 25, the first pin 25 is used for electrically connecting with the ground wire of the circuit board, one end of the portion of the second housing 22 corresponding to the second sub-board 42 is provided with a second pin 26, the second pin 26 is also used for electrically connecting with the ground wire of the circuit board, so that a 360-degree shielding effect can be achieved for the signal terminal in each of the insulators 12 of the two terminal modules 11; in a specific arrangement, the first pin 25 and the second pin 26 may also be in the form of fisheye needles as in the previous embodiments.

In the foregoing embodiment, the two terminal modules 11 can be respectively carried on the conductive plates 40, so that the structural strength of the connector can be improved. Moreover, in this embodiment, the two terminal modules 11 may share one conductive plate 40, and if the conductive plate 40 is also regarded as one housing structure, the embodiment can achieve a shielding effect of 360 degrees for the signal terminals in each of the insulators 12 in the two terminal modules 11 through three housing structures of the first housing 21, the second housing 22 and the conductive plate 40, thereby reducing shielding on one side and contributing to increase density of signal arrangement in the connector.

In addition, when the terminal module includes two terminal modules, the conductive member 30 may be configured as a strip structure shown in fig. 11 and 12, the conductive member 30 of the strip structure may extend from between two insulators 12 of the upper terminal module 11 to between two corresponding insulators 12 of the lower terminal module 11, that is, the two terminal modules 11 in this solution may be directly contacted, each conductive member 30 is independently configured, and the shielding schematic diagram thereof may be shown with reference to fig. 13.
