Description

Technical Field

[0001] The present invention relates to capacitor technology, and in particular to a supercapacitor energy storage module. Background Art

[0002] The connection between the capacitor module and the power module in the prior art mostly has the following problems: First, most of them adopt the arrangement method of PCB board + capacitor welding, which not only makes the plug-in assembly complicated and the PCB board warping and positioning inaccurate, but also has a high defect rate of the combination of the capacitor and the PCB board, and the resistance of the connection point is large, which inevitably leads to a certain amount of energy loss and insufficient resource utilization; second, when the arrangement method is unreasonable, it is easy to cause the PCB board space to be occupied, making it difficult to arrange and route the components on the PCB board, resulting in an increase in the PCB board area, thereby causing an increase in the volume of the controller.

[0003] When its supercapacitor is connected to other electronic components, it adopts plug-in connection, which is easy to disconnect or loosen during use, causing the supercapacitor to short-circuit or have poor contact, thus causing the equipment to malfunction. Summary of the invention

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0039] Example 1

[0041] The base 1 is provided with multiple docking seats 3, and the docking seats 3 are provided with symmetrically arranged mounting parts 7. A mounting hole 8 is provided in the middle of the mounting part 7. The docking seats 3 can be installed on the base 1 by bolts for easy disassembly and assembly. At the same time, the docking seats 3 can also be welded to the base 1 by welding.

[0042] A docking chamber 9 is formed in the middle of the docking seat 3 , and the docking member 4 with the conductive terminal 10 is inserted into the docking chamber 9 to contact with the internal contact terminal 11 to achieve electrical connection and limit the conductive terminal 10 at the same time.

[0043] A bearing protrusion 12 is provided in the middle of the docking chamber 9, and the bearing protrusion 12 is used to limit the position of the conductive terminal 10. The bearing protrusion 12 is provided with symmetrically arranged contact terminals 11, and the contact terminals 11 are arranged on the bearing protrusion 12 through the conductive rod 13. A movable hole 15 that cooperates with the pressure rod 14 is provided in the middle of the bearing protrusion 12, and the movable hole 15 is located between the symmetrically arranged contact terminals 11, and a spring 16 is provided in the movable hole 15.

[0044] The inner wall of the movable hole 15 is provided with a symmetrically arranged mounting groove 17, a sliding groove 18 and a rotationally symmetrically arranged arc groove 19. The arc groove 19 connects the mounting groove 17 and the sliding groove 18, and the angle between the mounting groove 17 and the sliding groove 18 is 90°. A guide slope 20 is provided at the connection between the sliding groove 18 and the arc groove 19, and the guide slope 20 can prevent the limit plate 21 from rotating when pressure is applied. When the limit plate 21 rotates at a certain angle, the guide slope 20 can guide the mounting protrusion 22 to the sliding groove 18 when the pressure rod 14 applies pressure.

[0045] A positioning groove 23 is provided at the upper end of the sliding groove 18. The arc angle of the arc groove 19 is also 90 degrees, so that after the mounting protrusion 22 is installed in the mounting groove 17, it is rotated 90 degrees so that the mounting protrusion 22 passes through the arc groove 19 from the mounting groove 17 to the arc groove 19, and then the mounting protrusion 22 is pushed to the positioning groove 23 under the elastic force of the spring 16.

[0046] A limit plate 21 is provided in the movable hole 15, and a symmetrically arranged mounting protrusion 22 is provided on the limit plate 21. The mounting protrusion 22 is installed in cooperation with the mounting groove 17 and the sliding groove 18. The mounting protrusion 22 is installed in the mounting groove 17, and the spring 16 is compressed, and the mounting protrusion 22 is placed in the positioning groove 23 through the arc groove 19.

[0047] Symmetrical holes 24 are provided on the limiting plate 21 . When installing the limiting plate 21 , tweezers are placed in the holes 24 to clamp the limiting plate 21 , and then installed in the movable hole 15 .

[0048] When the mounting protrusion 22 is placed in the positioning groove 23, the spring 16 is in a compressed state. After the pressure rod 14 applies pressure to the limiting plate 21, the mounting protrusion 22 is kept from entering the sliding groove 18 from the positioning groove 23, and the spring 16 is compressed by a certain distance. When the capacitor body 2 needs to be taken out from the docking seat 3, it is only necessary to press the capacitor body 2 again, so that the pressure rod 14 on the docking member 4 applies pressure to the limiting plate 21, and the limiting plate 21 applies pressure to the spring 16 again, so that the spring 16 is further compressed.

[0049] Example 2

[0050] The contact terminal 11 is composed of a contact section 25, a mounting section 26, and a plurality of oblique sections 27 for connecting the contact section 25 and the mounting section 26. The contact section 25 contacts the pressure section 28, and when the contact section 25 is subjected to pressure, the oblique section 27 is kept moving toward the mounting section 26.

[0051] In addition, a plurality of spherical protrusions 29 are provided on the contact section 25, and a spherical recess 30 matching with the spherical protrusions 29 is provided on the pressure section 28 to increase the contact area.

[0052] When the conductive terminal 10 is inserted into the docking chamber 9 along with the docking member 4, the conductive terminal 10 contacts the contact terminal 11, and the spherical protrusion 29 contacts the spherical depression 30. The conductive terminal 10 applies external pressure to the contact terminal 11 to keep the contact terminal 11 slightly pressed down and deformed. It is only necessary to keep the contact segment 25 and the pressure segment 28 in contact and squeeze, and it is also necessary to ensure that the contact terminal 11 can continue to be pushed down, so as to unlock the conductive terminal 10 and separate the docking member 4 from the docking seat 3.

[0053] The capacitor body 2 cooperates with the docking seat 3, and a docking piece 4 cooperating with the docking seat 3 is provided at the lower end of the capacitor body 2. A symmetrically arranged conductive terminal 10 is provided in the middle of the docking piece 4. The conductive terminal 10 is inserted into the docking chamber 9 and contacts with the symmetrically arranged contact terminals 11 to achieve electrical connection.

[0054] A hinge rod 31 and a positioning rod 32 are provided in the docking chamber 9, a first through hole 33 and a second through hole 34 are provided on the docking seat 3, the hinge rod 31 is arranged in the first through hole 33, and the positioning rod 32 is arranged in the second through hole 34. A retaining member 35 is provided on the hinge rod 31, the retaining member 35 is hinged on the hinge rod 31, a notch 36 is provided on the retaining member 35, a limiting rod 37 is provided in the notch 36, and the limiting rod 37 is connected to the positioning rod 32 through a tension spring 38.

[0055] The docking member 4 is provided with a vertical groove 39 and a transverse groove 40, and the elastic section 41 on the conductive terminal 10 cooperates with the vertical groove 39, and the transverse section 42 cooperates with the transverse groove 40. The docking member 4 also has a symmetrically arranged positioning extension 43 for limiting the deformation direction of the elastic section 41.

[0056] Example 3

[0057] The retaining member 35 is composed of a limiting end 44 and a pulling end 45. The limiting end 44 is provided with a first inclined surface 46 and a second inclined surface 47. The first inclined surface 46 is located at the upper end of the second inclined surface 47. The limiting rod 37 is arranged on the pulling end 45. The first inclined surface 46 is used for the pressure section 28 to push the first inclined surface 46 when the conductive terminal 10 is inserted, so that the retaining member 35 rotates, and the limiting end 44 rotates downward. Then, since the position of the retaining member 35 does not change, but only rotates, while the conductive terminal 10 moves, the conductive terminal 10 can continue to move downward, and the limiting end 44 is kept in the limiting opening 48 for limiting, and the conductive terminal 10 generates a reverse force under the elastic force of the contact terminal 11 and the spring 16, and the conductive terminal 10 is pushed upward, and the conductive terminal 10 is limited by the retaining member 35, so as to remain in the limited position.

[0058] After the conductive terminal 10 is inserted into the docking chamber 9 , pressure is applied to the contact terminal 11 to keep the contact terminal 11 in contact with the conductive terminal 10 . The conductive terminal 10 pushes the retaining member 35 to rotate on the hinge rod 31 , so that the tension spring 38 is stretched and the retaining member 35 limits the position of the conductive terminal 10 .

[0059] The conductive terminal 10 is composed of a vertical section 49, a transverse section 42, an elastic section 41, an arc section 50, an inclined section 51 and a pressure section 28 from top to bottom. An arc opening 52 is formed in the middle of the arc section 50. When the retaining member 35 is in the arc opening 52, the retaining member 35 does not contact the lowest point of the inner wall of the arc opening 52.

[0060] The inclined section 51 is provided with a limiting opening 48, the lower end of which is provided with a limiting protrusion 53, the limiting protrusion 53 is provided with a guiding inclined surface 54 and a limiting surface 55, and the limiting end 44 is placed in the limiting opening 48. A blocking protrusion 56 is formed at the connection between the inclined section 51 and the arc section 50.

[0061] A through hole 57 for accommodating the conductive rod 13 is provided in the middle of the docking seat 3 .

[0062] A pressure rod 14 is also provided on the docking member 4. The pressure rod 14 is located between the symmetrically arranged conductive terminals 10, and a limiting gap 58 is formed between the pressure rod 14 and the conductive terminals 10. When the capacitor body 2 is installed and pulled upward by an external force, the limiting protrusion 53 can drive the limiting end 44 to move upward, so that the retaining member 35 rotates upward, but because the retaining member 35 is hinged in the docking chamber 9 by the hinge rod 31, the retaining member 35 does not move. The conductive terminal 10 is pushed by the retaining member 35 to approach the pressure rod 14, so that the pressure rod 14 blocks the lower end of the conductive terminal 10, avoiding the limiting end 44 of the retaining member 35 from rotating to a horizontal state, and restricting the docking member 4 in the docking seat 3.

[0063] like Fig.15 As shown, at this time, the conductive terminal 10 has been in contact with the contact terminal 11, and the retaining member 35 limits the conductive terminal 10 so that it cannot be pulled out.

[0064] When the capacitor body 2 needs to be replaced, the capacitor body 2 only needs to be pressed toward the docking seat 3, and the pressure rod 14 compresses the spring 16, so that the inclined section 51 pushes the limiting end 44 on the retaining member 35, so that the limiting end 44 enters the arc-shaped opening 52, and under the tension of the tension spring 38, the limiting end 44 on the retaining member 35 is in a horizontal state, that is, the first inclined surface 46 is kept horizontal. Then, the capacitor body 2 is pulled to drive the conductive terminal 10 to move upward, and the arc-shaped opening 52 drives the limiting end 44 of the retaining member 35 to rotate upward, compressing the tension spring 38, and the retaining member 35 no longer restricts the conductive terminal 10, so that the capacitor body 2 can be taken out for replacement or maintenance.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
