Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and more particularly to a socket assembly with a detachable self-fixing spring. Background Art

[0002] At present, the socket component structure of small-sized crown springs needs to prevent them from falling out by closing the mouth or installing a sleeve, which involves many steps, affects the convenience of assembly and is costly. The socket component structure of large-sized crown springs needs to process a step larger than the wall thickness of the crown spring at the mouth during machining to prevent them from falling out. However, the mouth diameter of this structure is smaller than the outer diameter of the spring, which may cause the crown spring to deform when installing it, greatly reducing the life and current-carrying capacity of the crown spring, affecting the stable transmission of current, and there is a risk of ablation during use. Summary of the invention

[0003] The present invention overcomes the deficiencies of the prior art and provides a jack assembly with a detachable self-fixing spring, so as to solve the problems existing in the prior art.

[0004] In order to solve the above technical problems, one embodiment of the present invention adopts the following technical solution:

[0005] A self-locking and detachable fixed spring jack assembly, comprising a jack base and a supporting structure;

[0006] The support structure includes a contact flap and an elastic support flap, wherein the elastic support flap is installed at the front end of the contact flap, and the elastic support flap includes at least two support arms;

[0007] The support arm can be elastically expanded and contracted;

[0008] The support structure is installed in the socket base, and the socket base is provided with a limiting groove, and the limiting groove includes a rear limiting groove;

[0009] The rear limiting groove is engaged with the installed support arm, and compression holes are provided on the support structure, and the positions and number of the compression holes correspond to the support arm.

[0010] When in use, when the support structure is inserted into the socket base, the support arm of the elastic support flap will be compressed by pressure, and when the support arm reaches the limit groove, the support arm will expand again and be clamped on the limit groove, thereby achieving the fixation of the support structure as a whole relative to the socket base and preventing it from falling out of the socket base.

[0011] When the support structure needs to be taken out, the support structure needs to be compressed so that the support arm is no longer clamped on the limiting groove of the socket base, and then the support structure can be taken out.

[0012] A further technical solution is that the support structure is provided with an opening in the longitudinal direction.

[0013] The existing crown spring has an opening structure, that is, the processed crown spring sheet is rolled up for use as the crown spring. The opening structure is arranged in the longitudinal direction of the support structure so that the diameter of the support structure can be changed. When plugging, the support structure is stretched and not easy to be pulled out. When taking out, it can be compressed to reduce the diameter.

[0014] A further technical solution is that the limit groove includes a front limit groove;

[0015] The front limiting groove is clamped with the front end of the installed elastic supporting flap, and the distance between the front limiting groove and the rear limiting groove is the length from the front end of the elastic supporting flap to the rear end of the supporting arm.

[0016] After installation, the front limiting groove is engaged with the front end of the installed elastic support flap to prevent the elastic support flap from sliding forward.

[0017] A further technical solution is that a self-fixing flap is provided at the tail of the contact flap.

[0018] A further technical solution is that the self-locking and detachable fixing spring jack assembly further includes an elastic outer ring;

[0019] The elastic outer ring comprises a ring body and a protrusion block, wherein the ring body is made of elastic material and has an opening;

[0020] The top of the protrusion is spherical, and the position and number of the protrusion correspond to the compression holes. The elastic outer ring can play two roles. First, after installation, the protrusion of the elastic outer ring passes through the compression hole and contacts the support arm, which can provide friction for the support arm to prevent the support arm from sliding. Second, when it needs to be taken out, the protrusion can be directly compressed by compressing the elastic outer ring to compress the support arm, so that the support arm is no longer stuck on the limit groove of the socket base, and can be taken out.

[0021] A further technical solution is that the support arm is provided with fixing holes, and the positions and numbers of the fixing holes correspond to those of the compression holes;

[0022] The spherical shape on the top of the protruding block is clamped in the fixing hole.

[0023] The spherical snap connection at the top of the protrusion block in the fixing hole can further enhance the effect of the protrusion block in fixing the support arm. Since the top of the protrusion block is spherical, when the support arm is compressed, the support arm and the protrusion block can still slide relative to each other to complete locking and removal.

[0024] A further technical solution is that the number of the protrusion blocks is 4.

[0025] Compared with the prior art, the present invention has at least the following beneficial effects: the present invention has its own supporting structure, can realize the self-fixing function, does not require an additional limiting structure, and can increase the contact area with the socket. At the same time, the structure will not be deformed during the assembly process, thereby improving the reliability of assembly and the stability of the contact during use. When disassembly is required, the elastic outer ring is aligned with the compression hole, and the elastic supporting petals of the supporting structure are contracted. The supporting petals are subjected to inward circumferential pressure, and the supporting petals are contracted. At this time, the supporting force disappears, and it can be taken out from the inside of the socket. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] A self-locking and detachable fixed spring jack assembly, comprising a jack base 1, a support structure 2, and an elastic outer ring 3;

[0033] The support structure 2 includes a contact flap 21 and an elastic support flap 22. The elastic support flap 22 is installed at the front end of the contact flap 21. The elastic support flap 22 includes at least two support arms 23. In this embodiment, the number of the support arms 23 is four.

[0034] The contact petal 21 is a crown spring structure, which is manufactured by punching, and the self-supporting material is beryllium copper strip.

[0035] The support arm 23 can be elastically expanded and contracted;

[0036] The support structure 2 is installed in the jack base 1, and the jack base 1 is provided with limiting grooves, and the limiting grooves include a front limiting groove 11 and a rear limiting groove 12;

[0037] In this embodiment, the support structure 2 is provided with an opening in the longitudinal direction. It can be understood that the existing crown spring already has a structure with a longitudinal opening, and the elastic support petal 22 includes a cylinder and a support arm 23, wherein the cylindrical part can also be provided with a longitudinal opening. Furthermore, the support structure 2 can be in the shape of a sheet as a whole, and form a contact petal 21 and an elastic support petal 22 after curling.

[0038] The front limiting groove 11 is clamped with the front end of the installed elastic support flap 22 , and the distance between the front limiting groove 11 and the rear limiting groove 12 is the length from the front end of the elastic support flap 22 to the rear end of the support arm 23 .

[0039] The rear limiting groove 12 is engaged with the installed support arm 23 , and the support structure 2 is provided with compression holes 13 , and the positions and number of the compression holes 13 correspond to the support arm 23 .

[0040] In this embodiment, a self-fixing flap 24 is provided at the tail of the contact flap 21 .

[0041] The elastic outer ring 3 includes a ring body 31 and a protrusion block 32. The ring body 31 is made of elastic material and has an opening.

[0042] The top of the protrusion block 32 is spherical, and the position and number of the protrusion block 32 correspond to the compression holes 13 .

[0043] The support arm 23 is provided with fixing holes, and the positions and numbers of the fixing holes correspond to those of the compression holes 13;

[0044] After installation, the spherical shape at the top of the protruding block 32 is snap-fitted into the fixing hole.

[0045] When in use, when the support structure 2 is inserted into the socket base 1, the support arm 23 of the elastic support petal 22 will be compressed by pressure, and when the support arm 23 reaches the limiting groove, the support arm 23 expands again and is clamped on the limiting groove, thereby achieving the fixing of the support structure 2 as a whole relative to the socket base 1 and preventing it from falling out of the socket base 1.

[0046] When the installation is completed, the spherical top of the protrusion block 32 is engaged with the fixing hole, further improving the effect of the protrusion block 32 in fixing the support arm 23. Since the top of the protrusion block 32 is spherical, when the support arm 23 is compressed, the support arm 23 and the protrusion block 32 can still slide relative to each other to complete locking and removal.

[0047] When the support structure 2 needs to be taken out, the support structure 2 needs to be compressed. The elastic outer ring 3 can be directly compressed to make the protrusion block 32 compress the support arm 23 so that the support arm 23 is no longer stuck on the limiting groove of the socket base 1 and can be taken out.

[0048] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, it should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in the present application. More specifically, within the scope disclosed in the present application, multiple variations and improvements can be made to the components and / or layout of the subject combination layout. In addition to the variations and improvements made to the components and / or layout, other uses will also be apparent to those skilled in the art.
