Detailed Description

For better understanding of the above technical solutions, the following will describe in detail exemplary embodiments of the present application with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all embodiments of the present application, and it should be understood that the present application is not limited by the exemplary embodiments described herein.

The embodiment of the application discloses a conductor connecting piece which can be arranged in some devices or devices, for example, the conductor connecting piece can be used as an outer conductor in a radio frequency connector to realize signal communication between a plate and a plate; in addition, in the embodiment, the conductor connecting piece comprises the elastic contact and the supporting contact, and due to the limiting resilience and the supporting action of the supporting contact on the elastic contact, the elastic contact has a larger elastic deformation amount in the axial direction of the conductor connecting piece, so that the accumulated tolerance of a size chain caused by board-to-board installation and the like when the conductor connecting piece is used is absorbed more, and the durability of the elastic contact is improved.

In the embodiment of the present application, the conductor connector includes a conductor 10 and a support 20, referring to fig. 1, fig. 1 is a schematic structural diagram of the conductor 10, the conductor 10 includes a first barrel 11, the first barrel 11 has a first end and a second end, a plurality of elastic contacts 12 are disposed at the first end of the first barrel 11, the elastic contacts 12 are turned outwards from the first end of the first barrel 11, and form an end face of an electrical connection in an axial direction perpendicular to the first barrel, the end face can be in contact with a PCB or the like; it can be understood that, at this time, the elastic contact 12 has an elastic deformation amount in the axial direction of the first cylinder 11; also referring to fig. 2, the spring contact 12 is everted from the first end of the first barrel 11 at a first angle a.

Referring to fig. 3, fig. 3 is a schematic structural view of a support member 20, and similar to the conductor member 10, the support member 20 includes a second cylinder 21, the second cylinder 21 has a first end and a second end, a plurality of support contacts 22 are provided at the first end of the second cylinder 21, the support contacts 22 are turned outwards from the first end of the second cylinder 21, and a third angle of turning outwards of the support contacts 22 is smaller than the first angle a.

Next, fig. 4 is a schematic structural diagram of the conductor connector formed by assembling the conductor 10 and the support member 20, and referring to fig. 4, the second cylinder 21 of the support member 20 is sleeved outside the first cylinder 11 of the conductor 10, the second cylinder 21 is fixedly connected with the first cylinder 11, and the plurality of support contacts 22 and the plurality of elastic contacts 12 correspond to each other one by one; since the third angle of eversion of the support contact 22 is smaller than the first angle of eversion of the elastic contact 12, at this time, referring to fig. 5, the support contact 22 supports and restrains the elastic contact 12 so that the elastic contact 12 is everted at a second angle B smaller than the first angle a; that is, when the conductor member 10 is sleeved in the supporting member 20, the supporting contact 22 will limit the position of the elastic contact 12 and simultaneously exert a supporting force, which will balance the resilience of the elastic contact to the first angle, so that the existence of the supporting contact will force the elastic contact to balance at the second angle B.

That is, the supporting contact limits the elastic contact and provides a supporting force, so that the elastic contact is forced to rebound to a second angle smaller than the first angle; i.e. a limited downward elastic deformation e 1 of the spring contact itself during the spring contact connection, whereas in the present embodiment the supporting contact forces the spring contact to have an opposite elastic pre-deformation e 2 before the spring contact connection; thus, when the elastic contact is in elastic contact connection with a PCB board or the like, in conjunction with fig. 5, the process may be:

(1) the supporting contact limits and supports the elastic contact, so that the elastic contact is forced to generate a pre-deformation amount epsilon 2;

(2) the elastic contact is pressed by external force of a PCB (printed circuit board) and the like and returns to the first angle position;

(3) the elastic contact is continuously pressed by external force to generate inherent deformation epsilon 1;

(4) after the external force is released, the elastic contact returns to the first angle and then returns to the second angle under the action of the supporting contact.

In the embodiment, the elastic contact is provided with a reverse pre-deformation amount epsilon 2 in advance, so that a PCB (printed circuit board) and the like can firstly press the elastic contact to an inherent first angle and then continue to generate a deformation amount epsilon 1 downwards, namely, in the axial direction of the cylinder, the elastic deformation amount of the elastic contact is increased from the inherent epsilon 1 to epsilon 1+ epsilon 2 through the limit support of the support contact, the axial deformation amount of the elastic contact is increased, the accumulated tolerance of a size chain of the conductor connecting piece, which is introduced by board-to-board mounting and the like in use, can be absorbed more, and the durability of the elastic contact is improved; in addition, the elastic contact of the conductor connecting piece is not easy to damage, and the service life and the reuse rate are improved.

It can be appreciated that in connection with fig. 5, the support contact supports and constrains the spring contact such that the spring contact everts at a second angle that is less than the first angle. At this time, in terms of structure, it is necessary that the third angle at which the support contact is turned inside out is smaller than the first angle, or more specifically, the third angle is smaller than the second angle; in terms of materials, it is desirable that the elastic modulus of the support contact material be greater than the elastic modulus of the elastic contact material; thus, on one hand, the supporting contact can apply a supporting force to the elastic contact to force the elastic contact to rebound, and the elastic contact and the supporting contact are balanced at a certain second angle between the first angle and the third angle due to the interaction force; in another aspect, the support contact has a modulus of elasticity greater than the modulus of elasticity of the spring contact, such that the support force of the support contact is capable of carrying the spring back force of the spring contact.

In this embodiment, optionally, the first cylinder and the elastic contact are integrally formed, the second cylinder and the supporting contact are integrally formed, and both the elastic contact and the supporting contact may be in a reed structure; it will be appreciated that the conductor and support members may each be formed, for example, by a flat plate rolled into a cylindrical barrel which forms the first or second barrel, and then one end of the cylindrical barrel is split into a plurality of leaves which are turned outwards to form the spring or support contacts; the conductor piece is made of a conductor material, such as a beryllium copper material, a titanium copper material or other conductive materials, and is used for signal transmission; the support member may be a metal, alloy, stainless steel or plastic material, and the elastic modulus of the support contact material is greater than the elastic modulus of the elastic contact material.

In a possible embodiment, the second end of the elastic arm 122 has a contact end surface 121 perpendicular to the axial direction of the first cylinder 11.

Referring to fig. 11, the contact end surface 121 is the farthest position of the elastic contact 12 from the first end surface of the first barrel 11, and the contact end surfaces of the elastic contacts form an electrical connection end, or an electrical connection plane, which facilitates the contact connection of the elastic contact with a PCB or the like.

It should be noted that, in connection with fig. 5, the above-mentioned eversion angle of the spring contact is to be understood as the angle at which the contact end face deviates from the cylinder wall of the cylinder, wherein fig. 6 shows a schematic view of the eversion angle when the spring contact or the support contact is arc-shaped; moreover, the supporting contact may be similar to the elastic contact in shape, or may be in other shapes that can support and limit the elastic contact.

Meanwhile, it can be understood that at least one of the first cylinder of the conductor and the second cylinder of the support needs to have a buffer gap, or both the first cylinder and the second cylinder have a buffer gap.

In one possible embodiment, the second end of the first cylinder and the second end of the second cylinder are welded and fixed.

Alternatively, it can be understood that a through hole may be formed in the wall of the first cylinder, and then a press-riveting protrusion may be formed in the wall of the second cylinder, so that when the first cylinder is fitted to the second cylinder, the press-riveting protrusion passes through and protrudes inwardly from the through hole, and then the press-riveting protrusion is turned outward to press and rivet the through hole in the opposite direction.

Or, can understand, still can set up the blind hole in the position that first barrel and second barrel correspond, then make first barrel and second barrel fixed through the spacing of blind hole.

In order to increase the fixed connection between the first cylinder 11 and the second cylinder 21, a plurality of through holes 24 may be formed on the wall of the second cylinder 21, and correspondingly, a plurality of press-riveting protrusions 14 may be formed on the wall of the first cylinder 11.

In a possible embodiment, the plurality of elastic contacts 12 is uniformly distributed at the first end of the first cylinder 11, and correspondingly, the plurality of supporting contacts 22 is uniformly distributed at the first end of the second cylinder 21.

In one possible embodiment, the elastic contact is an elastic spring, and the supporting contact is a supporting spring, which is made of spring and has good flexibility.
