Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
Example 1:
as shown in fig. 1, an embodiment of the present invention provides a sliding electrically conductive coupling structure including a first coupling member 10 and a second coupling member 20. The first and second connectors 10 and 20 may be provided in two connectors that can be locked or unlocked, respectively. The electrical conduction of the two connectors is achieved by the first connecting member 10 contacting a specific portion of the second connecting member 20 in the two-connector locked state. The non-energization of the two connectors is achieved by the first connecting member 10 being separated from a specific portion of the second connecting member 20 during the unlocking of the two connectors.
As shown in fig. 2 and 3, the first connecting member 10 is an integrally formed structure, which is a resilient plate having a certain elasticity, and the first connecting member 10 is configured in an arch structure. The first connecting member 10 has a sheet-like fixed end 11 and a free end 12 extending obliquely from both ends of the fixed end 11 to the fixed end 11 on the same side.
The fixing end 11 has a fixing hole 111 formed in the middle thereof, and the first connecting member 10 can be fixed to a corresponding connector through the fixing hole 111. The fixed end 11 has a hook-shaped free end 12 extending from each end.
Each free end 12 comprises a sliding portion 121 and a conductive contact portion 122 arranged side by side.
In one embodiment, the number of the conductive contact portions 122 of each free end 12 is two, and the conductive contact portions 122 and the sliding portions 121 are separately disposed on both sides of the sliding portion 121. The sliding part 121 has a sliding surface 1211, the conductive contact part 122 has a conductive contact surface 1221, and the sliding part 121 is disposed to protrude from the conductive contact part 122 such that a height difference exists between the sliding surface 1211 and the conductive contact surface 1221. This difference in height enables electrical conduction between the conductive contact surface 1221 of the conductive contact portion 122 and the second connector 20 only when the sliding portion 121 is in the second position on the second connector 20.
In one embodiment, the sliding surface 1211 and the conductive contact surface 1221 are both smooth arcs.
As shown in fig. 4, the second connector 20 may be a circuit board, two receiving holes 21 are formed in the second connector 20, and a distance between the two receiving holes 21 is equal to a distance between two opposite sliding portions 121 of the first connector 10.
The second connecting member 20 is provided with a conductive member 22 around the receiving hole 21. In one embodiment, the conductive elements 22 are conductive contacts (static contacts in the background). The conductive contact piece is provided with a sliding channel 221 along the sliding direction of the first connecting member 10, and the accommodating hole 21 is arranged in the sliding channel 221. The height difference between the sliding surface 1211 and the conductive contact surface 1221 should be greater than the thickness of the conductive member 22, so as to ensure that the conductive contact portion 122 does not contact the conductive member 22 when the sliding portion 121 slides in the sliding channel 221.
The sliding channel 221 may be disposed completely through the conductive member 22 in the sliding direction of the first connecting member 10, or may be disposed partially through the sliding channel 221 in the sliding direction.
In one embodiment, the first connecting member 10 and the conductive member 22 are coated with tin plating.
As shown in fig. 5 to 8, the first connecting member 10 slides on the second connecting member 20, and when the first connecting member 10 is located at the first position (fig. 5), a certain gap exists between the conductive contact surface 1221 of the conductive contact portion 122 and the surface of the conductive member 22, and at this time, the first connecting member 10 and the second connecting member 20 are not electrically connected; when the second connecting member 20 is located at the second position (fig. 6-8), the sliding portion 121 is partially slid into the receiving hole 21, the conductive contact surface 1221 of the conductive contact portion 122 is in contact with the conductive member 22, and the first connecting member 10 and the second connecting member 20 are electrically connected.
When the first connecting element 10 slides back and forth on the second connecting element 20, the sliding part 121 slides in the sliding channel 221 of the conductive element 22, and the conductive contact part 122 does not contact with the conductive element 22, so that the conductive contact part 122 does not scratch the surface of the conductive element 22, and only after the first connecting element 10 moves to the second position, the sliding part 121 moves downwards into the accommodating hole 21, and the conductive contact part 122 contacts with the conductive element 22, so that the two connecting elements are electrically connected. When the first connecting member 10 needs to be moved again, the sliding portion 121 is cut out from the accommodating hole 21, so that the conductive contact portion 122 is lifted up and does not contact with the conductive member 22, and therefore, no scratch mark is generated on the conductive member 22 in the connection range with the conductive contact portion 122, thereby greatly improving the stability of the on-off control of the circuit between the two connecting members.
Example 2:
the difference between the embodiment 2 and the embodiment 1 is that in this embodiment, the conductive member is not provided with a sliding channel, but the conductive member is disposed to cover the accommodating hole, and the accommodating hole is provided with a through hole.
The sliding part of the first connecting piece is plated with an insulating layer, or the sliding part of the first connecting piece is made of insulating materials and is arranged to be convex to the conductive contact part.
In this embodiment, when the insulating sliding portion contacts with the conductive member, the first connecting member and the second connecting member are not electrically conducted, and also, only when the insulating sliding portion moves down into the accommodating hole, the conductive contact portion contacts with the conductive member, so that the electrical conduction between the two connecting members can be realized.
Through the mode, although the first connecting piece and the conductive piece can generate scraping when sliding, the scraping range is limited to the contact range of the sliding part, the contact range of the conductive piece and the conductive contact part of the first connecting piece is not influenced, and the friction between the conductive contact part plated with the tin plating layer and the conductive piece is avoided, so that the first connecting piece and the conductive piece can be ensured to be stably and reliably contacted.
Compared with the prior art, the sliding electric conduction connecting structure provided by the embodiment of the invention has the advantages that the conductive contact parts and the sliding parts with different heights are arranged on the first connecting piece, so that the friction area between the first connecting piece and the second connecting piece is reduced, meanwhile, the point contact (surface contact) between the conductive contact parts and the conductive pieces is realized through the sliding friction between the sliding parts and the second connecting piece, the damage to the conductive contact parts and the plating layers on the conductive pieces is reduced, and the contact stability between the first connecting piece and the second connecting piece is ensured.
The sliding conductive connecting structure can adopt the tin plating layer to coat the first connecting piece and the conductive piece, does not need to worry that the tin plating layer is easy to be damaged by friction, and greatly reduces the manufacturing cost of the connecting piece.
In the sliding and electrically conductive connecting structure of the embodiment of the invention, when the first connecting piece is contacted with the conductive piece, although the first connecting piece slides in the horizontal direction, the moment of contact between the conductive contact part and the conductive piece is in the vertical direction, and surface damage caused by sliding friction does not exist, so that the high-specification environmental requirements of customers can be met by adopting a scheme with low cost for the surface plating layers of the first connecting piece and the conductive piece.
The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. It is not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and its practical application to enable one skilled in the art to make and use various exemplary embodiments of the invention and various alternatives and modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims and their equivalents.
