Description

Technical Field

[0001] The utility model relates to the technical field of supercapacitors, and more particularly to a single supercapacitor with a stable structure. Background Art

[0002] Supercapacitors are a type of chemical power source with the advantages of short charging and discharging time, long cycle life, high power density, wide operating temperature range, and environmental protection. These advantages make them highly valuable and have great market potential in the fields of transportation, electricity, communications, national defense, and electronic products.

[0003] Existing supercapacitors usually place the capacitor unit in a shell and set resin on top for sealing. However, during use, the stability of the connection between the filled resin and the shell is poor. After long-term use, the resin may separate from the shell, thereby affecting the normal use of the supercapacitor.

[0004] Therefore, a new technical solution is urgently needed to solve the above technical problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a single supercapacitor with a stable structure.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a structurally stable single-body supercapacitor, comprising a shell and a capacitor monomer, a resin layer is provided on the top of the capacitor monomer in the shell, a positioning member is provided in the shell, vertical grooves running through the top of the shell are provided on both sides of the inner wall of the shell, the positioning member comprises two plug-in rods inserted in the two grooves, a connecting rod is fixedly connected between the top ends of the two plug-in rods, and the connecting rod is located above the capacitor monomer and inside the resin layer.

[0007] By adopting the above technical solution, during production and processing, the capacitor unit is placed in the housing, and the connecting rod is inserted into the corresponding groove so that the connecting rod is located above the capacitor unit. Liquid resin is then poured into the housing, thereby forming a resin layer on top of the capacitor unit and positioning the connecting rod within the resin layer as a whole. When placing the plug-in rod, glue is applied to its surface to form a glue layer, thereby ensuring the stability of the connection between the plug-in rod, the connecting rod, and the housing. Ultimately, the stability of the connection between the resin layer and the housing is ensured, effectively preventing it from detaching from the housing during use, thereby improving its performance and service life.

[0008] The utility model is further configured as follows: a glue layer is provided between the plug rod and the groove.

[0009] The utility model is further configured as follows: an outer connecting ring and an inner connecting ring are provided on the connecting rod, and the outer connecting ring and the inner connecting ring are both located inside the resin layer.

[0010] The utility model is further configured as follows: the connecting rod is provided with a plurality of first through slots penetrating through both side walls thereof.

[0011] The utility model is further configured as follows: the outer connecting ring and the inner connecting ring are provided with a plurality of second through grooves penetrating the upper and lower surfaces thereof.

[0012] The present invention is further configured as follows: a plurality of abutment blocks are provided on the bottom surface of the shell along its circumferential direction.

[0013] The present invention has the following beneficial effects: during production and processing, the capacitor unit is placed in the housing, and the connecting rod is inserted into the corresponding groove so that the connecting rod is located above the capacitor unit. Liquid resin is then poured into the housing, thereby forming a resin layer on top of the capacitor unit, and the connecting rod is located within the resin layer and becomes a whole. When placing the plug-in rod, glue is applied to its surface to form a glue layer, thereby ensuring the stability of the connection between the plug-in rod, the connecting rod and the housing, and ultimately ensuring the stability of the connection between the resin layer and the housing, effectively preventing it from detaching from the housing during use, thereby improving its use effect and service life.

[0019] The present invention will be described in further detail below with reference to the accompanying drawings.

[0020] Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0021] As shown in the figure, a structurally stable single-cell supercapacitor includes a housing 1 and a capacitor cell 2. A resin layer 3 is provided on top of the capacitor cell 2 within the housing 1. A positioning member 4 is provided within the housing 1. Vertical grooves 5 are provided on both sides of the inner wall of the housing 1 and extend through the top of the housing 1. The positioning member 4 includes two connecting rods 6 inserted into the two grooves, and a glue layer (not shown in the figure) is provided between the connecting rods 6 and the grooves. A connecting rod 7 is fixedly connected between the top ends of the two connecting rods 6. The connecting rod 7 is located above the capacitor cell 2 and inside the resin layer 3.

[0022] During production and processing, the capacitor monomer 2 is placed in the shell 1, and the connecting rod 7 is inserted into the corresponding groove 5 so that the connecting rod 7 is located above the capacitor monomer 2. Liquid resin is then poured into the shell 1. After solidification, a resin layer 3 is formed on the top of the capacitor monomer 2, and the connecting rod 7 is located in the resin layer 3 and becomes a whole. When placing the plug-in rod 6, glue is applied to its surface to form a glue layer, thereby ensuring the stability of the connection between the plug-in rod 6, the connecting rod 7 and the shell 1, and finally ensuring the stability of the connection between the resin layer 3 and the shell 1, effectively preventing it from detaching from the shell 1 during use, so as to improve its use effect and service life.

[0023] The connecting rod 7 is provided with a horizontal outer connecting ring 8 and an inner connecting ring 9, both of which are located inside the resin layer 3. The connecting rod 7 is provided with a plurality of first through-slots 10 extending through its side walls, and the outer connecting ring 8 and the inner connecting ring 9 are provided with a plurality of second through-slots 11 extending through their upper and lower surfaces. This reduces the overall mass of the connecting rod 7, and when liquid resin is poured in, the resin flows into the first through-slots 10 and the second through-slots 11 and solidifies, further improving the stability of the resin layer 3 after solidification.

[0024] The capacitor monomer 2 includes a capacitor body 12 and a guide pin 13 extending from the top thereof. The two guide pins 13 are located on both sides of the connecting rod 7 and extend from the surface of the resin layer 3 between the inner connecting ring 9 and the outer connecting ring 8 .

[0025] The bottom surface of the shell 1 is evenly provided with four abutment blocks 14 along its circumferential direction. When the capacitor monomer 2 is placed in, it is placed on the abutment blocks 14, so that the capacitor monomer 2 and the bottom of the shell 1 form a cavity, which is used to accommodate the electrolyte that may overflow when the capacitor monomer 2 leaks.

[0026] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
