[0002] Some connectors have metal housings, and the shielding layer of the shielded cable is electrically connected to the metal housing through a shielding ring. The metal housing is fixed to the mounting base and electrically connected to the mounting base, thereby achieving overall shielding and conduction. However, the electrical connection between the metal housing and the mounting base is a surface contact, especially the contact between two cast surfaces, which results in poor conductivity and shielding performance. Improvement solutions are needed to obtain better shielding performance. Utility Model Content

[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0028] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0031] like Figure 1-4 As shown, this embodiment provides a conductive element 3, which is disposed between two contact surfaces with a gap and electrically connects the two contact surfaces. It can be understood that the two contact surfaces can be any two adjacent surfaces that need to be electrically connected.

[0032] Further description: The conductive component 3 includes a base 31, and two ends of the base 31 are respectively connected to contact portions 32 that extend outward. The contact portions 32 can be elastically deformed and are provided with contacts for electrical connection with the corresponding contact surfaces. The contacts are specifically located on the side of the contact portion 32 facing the corresponding contact surface.

[0033] The aforementioned conductive component 3 improves the electrical connection performance of the surface contact through elastic contact of the contacts, resulting in better conductivity and shielding performance, thereby meeting higher shielding requirements.

[0034] Furthermore, in order to enable the conductive component 3 to be fitted with columnar parts such as bolts for easy assembly, in this embodiment, the base 31 is annular, or cylindrical, or can be understood as the radial cross-section of the base 31 being annular in its axial extension.

[0035] Of course, it is understood that in other embodiments, the substrate may also be a polygon shape, that is, the radial cross section of the substrate in the axial extension is a polygon shape, such as a regular hexagon, a square, or an irregular polygonal combination shape.

[0036] More specifically, such as Figure 3-4 As shown, in this embodiment, in order to make the base 31 elastically hold the bolt and make it easier to insert the base 31 onto the bolt, the base 31 is provided with an axially penetrating opening 34, so that the cross-section of the base 31 is C-shaped, so that the base 31 can elastically expand outward.

[0037] As an extension of functionality, such as Figure 3-4 As shown, in this embodiment, the two ends of the base 31 are respectively connected to limiting portions 33. One end of the limiting portion 33 is connected to the base 31, and the other end is offset towards the inside of the base 31. The limiting portion 33 can be clamped on the outer periphery of the bolt, which is beneficial for limiting the position of the conductive component 3 on the bolt.

[0038] Furthermore, based on considerations of processing convenience, such as Figure 3 As shown, in this embodiment, the contact portion 32 is a sheet-like structure integrally formed on the substrate 31. More specifically, the conductive element 3 in this embodiment is a part integrally formed by a stamping process, and the aforementioned limiting portion 33 and contact point are also formed by a stamping process.

[0039] Furthermore, considering better contact performance, this embodiment adopts a contact scheme combining point contact and line contact, such as... Figure 3 As shown, the contacts include a first contact 321 and a second contact 322. The first contact 321 is a convex hull structure, forming a point contact scheme. The second contact 322 is a bent structure that is deflected from the edge of the sheet structure to the corresponding contact surface, forming a line contact scheme.

[0040] Furthermore, in order to balance the contact forces, such as Figure 3 As shown, in this embodiment, each sheet structure has two second contacts 322 which are arranged opposite to each other on both sides of the contact portion 32 in the overhang direction, and the first contact 321 is located between the opposite second contacts 322.

[0041] Of course, it is understood that in other embodiments, the number of second contacts and the number of first contacts can be flexibly adjusted according to size and needs.

[0042] Furthermore, considering factors related to equilibrium forces, such as Figure 3 As shown, in this embodiment, each end of the substrate 31 has multiple limiting portions 33 and contact portions 32, and the limiting portions 33 and contact portions 32 are arranged alternately in the circumferential direction.

[0043] like Figure 3 As shown, in this embodiment, the conductor is obviously a three-dimensional symmetrical structure that is mirror-symmetrical with respect to the radial plane located in the middle.

[0044] like Figure 1-4 As shown, the embodiment of this utility model also provides a connecting component, including a connecting housing 1 and a bolt 2. The connecting housing 1 is provided with a mounting hole 11. After the bolt 2 passes through the mounting hole 11, it connects the connecting housing 1 to the mounting base 4. The mounting hole 11 is a stepped hole structure with one end larger and the other end smaller facing the mounting base 4. A conductive element 3, as described above, is installed on the bolt 2 and is housed in the larger end of the mounting hole 11. The contacts at both ends of the conductive element 3 are electrically connected to the stepped part of the stepped hole structure and the mounting base 4, respectively. That is, the end face of the stepped part of the stepped hole structure and the end face of the mounting base 4 constitute the aforementioned two contact surfaces with gaps. The two contact surfaces are the first contact surface 12 and the second contact surface 41, respectively.

[0045] In the case where the mounting base 4 is a cast surface, a relatively flat second contact surface 41 can be formed by milling to facilitate conductive contact.

[0046] Furthermore, in order to limit the conductive component 3 on the bolt 2 and prevent the bolt 2 from loosening, the bolt 2 includes a head 21 and a shank, such as... Figure 4 As shown, the rod includes a first rod segment 22 with external threads 221 and a second rod segment 23 located between the first rod segment 22 and the head 21. The outer diameter of the second rod segment 23 is smaller than the outer diameters of the head 21 and the first rod segment 22. The base 31 has an axially penetrating opening 34. After the base 31 elastically expands outward, it is inserted into the second rod segment 23. At this time, the ends of the limiting portions 33 at both ends of the base 31 are attached to the outer surface of the second rod segment 23 and can be axially stopped and engaged with the corresponding ends of the first rod segment 22 and the corresponding ends of the head 21, respectively, thereby restricting the base 31 onto the second rod segment 23. Furthermore, when the conductive element 3 is inserted into the second rod end after the bolt 2 is inserted into the mounting hole 11, because the base 31 is restricted onto the second rod segment 23, and based on the stop engagement between the contact portion 32 near the head 21 and the first contact surface 12, the bolt 2 cannot be removed from the mounting hole 11, thereby enabling the pre-installation of the bolt 2, which facilitates the subsequent connection of the connecting assembly to the mounting base surface 4.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
