[0039] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0040] In view of the problem that the integrated insulating sheet in traditional connector manufacturing makes the installation of grounding components difficult, this application provides a connector 10 that facilitates the installation of grounding components.

[0041] Please refer to Figures 1-3 The connector 10 includes a plurality of contact modules 1 arranged in a plurality of ways. For ease of understanding, the direction in which the plurality of contact modules 1 are arranged is defined as the first direction X. Each contact module 1 includes a plurality of terminals 11 extending along the second direction Y and spaced apart along the third direction Z, and an insulating sheet 12 formed on the terminal 11. The first direction X, the second direction Y and the third direction Z are orthogonal to each other.

[0042] In some implementation methods, please refer to Figure 4Terminal 11 includes a contact portion 112, a middle portion 113, and a mounting portion 114 connected together. The contact portion 112 is exposed on one side of the insulating sheet 12 along the second direction Y. The middle portion 113 is located inside the insulating sheet 12. The mounting portion 114 is exposed at the bottom of the insulating sheet 12 along the third direction Z. The contact portion 112 is used for signal connection with the component. At least a portion of the middle portion 113 is exposed on the wall or edge of the insulating sheet 12 for various processes in the production and testing process. The mounting portion 114 is used for mounting the connector 10 on the component. That is, through the arrangement of the contact portion 112 and the mounting portion 114, the mounting of the contact module 1 on the component and the signal connection between the two can be ensured.

[0043] Please continue to refer to Figure 2 The insulating sheet 12 includes a discretely arranged first part 121 and a second part 122. The terminals 11 described above are formed in both the first part 121 and the second part 122. The middle part 113 of the terminal 11 is exposed on the wall or edge of the first part 121 and the second part 122. The first parts 121 of all contact modules 1 are connected along the first direction X to form a first module 3. The second parts 122 of all contact modules 1 are connected along the first direction X to form a second module 4. That is, the first module 3 and the second module 4 are also discrete structures. The first module 3 and the second module 4 are connected by a connection structure. Connecting the two by the connection structure can improve the connection stability of the first module 3 and the second module 4.

[0044] It should be noted that when multiple first parts 121 form a first module 3 and multiple second parts 122 form a second module 4, the middle part 113 of the exposed terminal 11 on the first part 121 is shielded by the adjacent first part 121, and the middle part 113 of the terminal 11 included on the second part 122 is shielded by the adjacent second part 122. This can reduce the impedance and loss of the connector 10 during application and improve the transmission performance of the connector 10.

[0045] In some embodiments, the connection between the first parts 121 of the plurality of contact modules 1 and the connection between the second parts 122 of the plurality of contact modules 1 are, but not limited to, interlocking connection, snap hook connection or adhesive connection; the connection between the first module 3 and the second module 4 is, but not limited to, interlocking connection, snap hook connection or adhesive connection, and can be selected according to actual needs.

[0046] Optionally, the connection structure between the first module 3 and the second module 4 in this application is a hook-and-groove structure 5. Please refer to [link / reference needed]. Figure 3The hook-and-groove structure 5 includes a hook portion 51 and a groove portion 52. At least one hook portion 51 is distributed on at least a portion of the edge of the first portion 121 facing the second portion 122, and at least one groove portion 52 is distributed on at least a portion of the edge of the second portion 122 facing the first portion 121. The number and spatial position of the hook portions 51 and the groove portions 52 are arranged in a one-to-one correspondence. The hook portion 51 includes a connecting portion 511 and a fixing portion 512. The connecting portion 511 is connected to the edge of the first portion 121 facing the second portion 122 through the fixing portion 512. The connecting portion 511 extends along the second direction Y and the fixing portion 512 is fixed. Part 512 extends along the third direction Z, that is, the hook part 51 is approximately L-shaped. When the first module 3 and the second module 4 are engaged, the fixing part 512 of the first module 3 is embedded in the groove part 52 of the second module 4, so that the first module 3 and the second module 4 can be connected by the engagement of the hook part 51 and the groove part 52. The separation of the first module 3 and the second module 4 is restricted by geometric constraints. Furthermore, the connecting part 511 of the hook part 51 and the fixing part 512 are approximately right-angled. When the fixing part 512 engages with the groove part 52, the connection stability of the two can be further improved.

[0047] In some embodiments, the first module 3, the connecting portion 511, and the fixing portion 512 together enclose a receiving portion 53 recessed along the second direction Y. The second module 4 also includes a locking protrusion 54 extending along the second direction Y. The locking protrusion 54 of the second module 4 is configured to be embedded in the receiving portion 53 of the first module 3. Through the cooperation between the receiving portion 53 and the locking protrusion, the connection stability between the first module 3 and the second module 4 is higher.

[0048] In some embodiments, the fixing portion 512 is provided with a first guide slope 5121, and the wall surface of the groove portion 52 corresponding to the first guide slope 5121 is provided with a second guide slope 521. When the first module 3 and the second module 4 are engaged, the first guide slope 5121 and the second guide slope 521 are configured to guide the fixing portion 512 into the groove portion 52. The cooperation of the first guide slope 5121 and the second guide slope 521 can guide the hook portion 51 to correctly align with the groove portion 52, thereby improving the assembly efficiency of the first module 3 and the second module 4.

[0049] In some embodiments, the hook portion 51 and the groove portion 52 are interference fit, and the connection between the two is more stable.

[0050] The connector 10 also includes a first grounding element 2, which is disposed between the first module 3 and the second module 4 and electrically connected to some terminals 11.
