     2. Description of Related Art 
     The winding-type capacitor includes a capacitor core, a casing, and a sealing cover. The capacitor core has an anode foil coupled to an anode terminal, a cathode foil coupled to a cathode terminal, a separator, and an electrolyte layer.

The electrolyte layer is formed between the anode foil and the cathode foil. The casing has an opening for receiving the capacitor core. The sealing cover can be used to seal the casing, and the anode terminal and the cathode terminal can pass through a through hole of the sealing cover. A given space is provided between the sealing cover and the capacitor core. A stopper for securing the space is provided on at least one of the anode terminal and the cathode terminal. However, the leakage current (LC) of the winding capacitor is increased and a short circuit of the winding capacitor may occur after diverging two pins of the winding capacitor. 
     SUMMARY OF THE INVENTION 
     One aspect of the instant disclosure relates to a capacitor detection system and a passive-type pin-diverging module thereof. 
     One of the embodiments of the instant disclosure provides a passive-type pin-diverging module applied to two conductive pins of a capacitor, comprising a base structure and a rotatable structure. The rotatable structure is rotatably disposed on the base structure, and the rotatable structure has a curved surface. The two conductive pins of the capacitor respectively pass through two through holes of a seat board, each conductive pin has a lateral contact surface, the two lateral contact surfaces of the two conductive pins of the capacitor concurrently slidably contact the curved surface of the rotatable structure so as to diverge the two conductive pins of the capacitor, and the seat board is held by the two diverged conductive pins so as to prevent the seat board from being separated from the capacitor. The friction resistance between the conductive pin and the rotatable structure is decreased due to the sliding contact between the lateral contact surface of the conductive pin and the curved surface of the rotatable structure. 
     Another one of the embodiments of the instant disclosure provides a capacitor detection system, comprising a pin-flattening module, a passive-type pin-diverging module, a pin-positioning module, and an electrical performance testing module. The pin-flattening module is used for flattening two conductive pins of a capacitor. The passive-type pin-diverging module is adjacent to the pin-flattening module, and the passive-type pin-diverging module comprising a base structure and a rotatable structure. The rotatable structure is rotatably disposed on the base structure. The rotatable structure has a curved surface, the two conductive pins of the capacitor respectively pass through two through holes of a seat board, each conductive pin has a lateral contact surface, the two lateral contact surfaces of the two conductive pins of the capacitor concurrently slidably contact the curved surface of the rotatable structure so as to diverge the two conductive pins of the capacitor, and the seat board is held by the two diverged conductive pins so as to prevent the seat board from being separated from the capacitor. The pin-positioning module is adjacent to the passive-type pin-diverging module for bending the two conductive pins and positioning the two conductive pins on the seat board. The electrical performance testing module is adjacent to the pin-positioning module for testing the electrical performance of the capacitor. 
     Yet another one of the embodiments of the instant disclosure provides a passive-type pin-diverging module, comprising a base structure and a rotatable structure. The rotatable structure is rotatably disposed on the base structure, and the rotatable structure has a curved surface. The two conductive pins of a capacitor respectively concurrently slidably contact the curved surface of the rotatable structure so as to diverge the two conductive pins of the capacitor, and a seat board is held by the two diverged conductive pins so as to prevent the seat board from being separated from the capacitor. 
     More particularly, the base structure includes a first base body and a second base body detachably connected to the first base body, the first base body has a first base seat and a first pivot seat disposed on the first base seat, the second base body has a second base seat detachably connected to the first base seat and a second pivot seat disposed on the second base seat, and the rotatable structure is pivotably disposed between the first pivot seat and the second pivot seat. 
     More particularly, the rotatable structure includes a pivot axle detachably connected between the first pivot seat and the second pivot seat and a pivot roller disposed between the first pivot seat and the second pivot seat and pivotably disposed around the pivot axle, wherein the curved surface is a circular surface of the pivot roller, and the two lateral contact surfaces of the two conductive pins of the capacitor concurrently slidably contact the circular surface of the pivot roller for diverging the two conductive pins so as to make the two conductive pins incline toward a bottom side of the seat board by a predetermined angle, wherein the friction resistance between the conductive pin and the pivot roller is decreased due to the sliding contact between the lateral contact surface of the conductive pin and the circular surface of the pivot roller. 
     More particularly, the rotatable structure includes a pivot axle detachably connected between the first pivot seat and the second pivot seat and a pivot ball disposed between the first pivot seat and the second pivot seat and pivotably disposed around the pivot axle, wherein the curved surface is a spherical surface of the pivot ball, and the two lateral contact surfaces of the two conductive pins of the capacitor concurrently slidably contact the spherical surface of the pivot ball for diverging the two conductive pins so as to make the two conductive pins incline toward a bottom side of the seat board by a predetermined angle, wherein the friction resistance between the conductive pin and the pivot ball is decreased due to the sliding contact between the lateral contact surface of the conductive pin and the spherical surface of the pivot ball. 
     More particularly, the capacitor detection system further comprises a heat-generating module disposed between the pin-positioning module and the electrical performance testing module, wherein the heat-generating module provides a predetermined heat source to the capacitor so as to release stresses in the capacitor. 
     Therefore, the two lateral contact surfaces of the two conductive pins of the capacitor can concurrently slidably contact the curved surface of the rotatable structure so as to diverge the two conductive pins P of the capacitor, so that the seat board can be held by the two diverged conductive pins so as to prevent the seat board from being separated from the capacitor. Please note, the friction resistance between the conductive pin and the rotatable structure can be decreased due to the sliding contact between the lateral contact surface of the conductive pin and the curved surface of the rotatable structure. More precisely, the friction resistance between the conductive pin and the rotatable structure is decreased, so that the reaction force applied to the two conductive pins and the capacitor due to the sliding contact between the lateral contact surface and the curved surface can be decreased (or the structural variation of a junction between the conductive pin and the capacitor can be decreased, and an outer force applied to an inner structure of the capacitor can be decreased). Therefore, the capacitor provided by the instant disclosure can avoid increasing leakage current (LC) and causing a short circuit.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Embodiments of a capacitor detection system and a passive-type pin-diverging module thereof according to the instant disclosure are described herein. Other advantages and objectives of the instant disclosure can be easily understood by one skilled in the art from the disclosure. The instant disclosure can be applied in different embodiments. Various modifications and variations can be made to various details in the description for different applications without departing from the scope of the instant disclosure. The drawings of the instant disclosure are provided only for simple illustrations, but are not drawn to scale and do not reflect the actual relative dimensions. The following embodiments are provided to describe in detail the concept of the instant disclosure, and are not intended to limit the scope thereof in any way. 
     First Embodiment 
     Referring to  FIG. 1  to  FIG. 8 , the first embodiment of the instant disclosure provides a capacitor detection system S, comprising: a pin-flattening module  1 , a passive-type pin-diverging module  2 , a pin-positioning module  3 , and an electrical performance testing module  5 . The term passive-type means that the passive-type pin-diverging module  2  can passively contact two conductive pins P of a capacitor C so as to diverge, separate, or split the two conductive pins P of the capacitor C as shown in  FIG. 7 . 
     First, referring to  FIG. 1  to  FIG. 3 , two cylindrical conductive pins P′ of the capacitor C can be flattened by the pin-flattening module  1  to form two flat-shaped conductive pins P. For example, the capacitor C may be a winding solid electrolytic capacitor,  FIG. 2  shows a lateral, schematic view before flattening of the two conductive pins P of the capacitor C according to the instant disclosure, and  FIG. 3  shows a lateral, schematic view after flattening of the two conductive pins P of the capacitor C according to the instant disclosure. In other words, the two cylindrical conductive pins P′ of the capacitor C can be flattened by the pin-flattening module  1 , so that the shape of the conductive pin can be changed from cylindrical to flat. As shown in  FIG. 3 , after the cylindrical conductive pin P′ of the capacitor C is flattened by the pin-flattening module  1  to form the flat-shaped conductive pin P, a flattened lateral contact surface P 10  is formed on an inner side of the flat-shaped conductive pin P. 
     Moreover, referring to  FIG. 1  and  FIG. 4  to  FIG. 6 , the passive-type pin-diverging module  2  is adjacent to the pin-flattening module  1  for diverging the two conductive pins P of the capacitor C, and the passive-type pin-diverging module  2  includes a base structure  20  and a rotatable structure  21 . In addition, the rotatable structure  21  is rotatably disposed on the base structure  20 , and the rotatable structure  21  has a curved surface  2100 . For example, the curved surface  2100  may be a regular curved surface or an irregular curved surface. 
     Therefore, referring to  FIG. 5  and  FIG. 6 , the two conductive pins P of the capacitor C can respectively pass through two through holes B 10  of a seat board B, and each conductive pin P has a lateral contact surface P 10 . The two lateral contact surfaces P 10  of the two conductive pins P of the capacitor C can concurrently slidably contact the curved surface  2100  of the rotatable structure  21  so as to diverge the two conductive pins P of the capacitor C, so that the seat board B can be held by the two diverged conductive pins P so as to prevent the seat board B from being separated from the capacitor C. Please note, the friction resistance between the conductive pin P and the rotatable structure  21  can be decreased due to the sliding contact between the lateral contact surface P 10  of the conductive pin P and the curved surface  2100  of the rotatable structure  21 . More precisely, the friction resistance between the conductive pin P and the rotatable structure  21  is decreased, so that the reaction force applied to the two conductive pins P and the capacitor C due to the sliding contact between the lateral contact surface P 10  and the curved surface  2100  can be decreased (or the structural variation of a junction between the conductive pin P and the capacitor C can be decreased, and an outer force applied to an inner structure of the capacitor C can be decreased). Therefore, the capacitor C provided by the instant disclosure can avoid increasing leakage current (LC) and causing a short circuit. 
     For example, referring to  FIG. 4  to  FIG. 6 , the base structure  20  includes a first base body  201  and a second base body  202  detachably connected to the first base body  201 . In addition, the first base body  201  has a first base seat  2011  and a first pivot seat  2012  vertically disposed on the first base seat  2011 , the second base body  202  has a second base seat  2021  detachably connected to the first base seat  2011  and a second pivot seat  2022  vertically disposed on the second base seat  2021 , and the rotatable structure  21  is pivotably disposed between the first pivot seat  2012  and the second pivot seat  2022 . 
     Following the above description, the rotatable structure  21  includes a pivot axle  211  (such as a fixed axle or a ball-bearing axle) detachably connected between the first pivot seat  2012  and the second pivot seat  2022  and a pivot roller  212  (such as a general roller or a ball bearing) disposed between the first pivot seat  2012  and the second pivot seat  2022  and pivotably disposed around the pivot axle  211 . In addition, the curved surface  2100  may be a circular surface  2120  of the pivot roller  212 , and the two lateral contact surfaces P 10  of the two conductive pins P of the capacitor C can concurrently slidably contact the circular surface  2120  of the pivot roller  212  for diverging the two conductive pins P so as to make the two conductive pins P incline toward a bottom side of the seat board B by a predetermined angle θ, so that the seat board B can be held by the two diverged conductive pins P so as to prevent the seat board B from being separated from the capacitor C. Please note, the friction resistance between the conductive pin P and the pivot roller  212  can be decreased due to the sliding contact between the lateral contact surface P 10  of the conductive pin P and the circular surface  2120  of the pivot roller  212 . More precisely, the friction resistance between the conductive pin P and the pivot roller  212  is decreased, so that the reaction force applied to the two conductive pins P and the capacitor C due to the sliding contact between the lateral contact surface P 10  and the circular surface  2120  can be decreased (or the structural variation of a junction between the conductive pin P and the capacitor C can be decreased, and an outer force applied to an inner structure of the capacitor C can be decreased). Therefore, the capacitor C provided by the instant disclosure can avoid increasing leakage current (LC) and causing a short circuit. 
     Furthermore, referring to  FIG. 1 ,  FIG. 7 , and  FIG. 8 , the pin-positioning module  3  is adjacent to the passive-type pin-diverging module  2  for bending the two conductive pins P and positioning the two conductive pins P on the seat board B. For example, the two conductive pins P can be positioned on two positioning grooves B 11  of the seat board B. In addition, the electrical performance testing module  5  is adjacent to the pin-positioning module  3  for testing the electrical performance of the capacitor C. For example, the electrical performance testing module  5  can provide two testing pins (not shown) to electrically contact the two conductive pins P of the capacitor C so as to test the electrical performance of the capacitor C. 
     Second Embodiment 
     Referring to  FIG. 9  and  FIG. 10 , the second embodiment of the instant disclosure provides a passive-type pin-diverging module  2  for diverging the two conductive pins P of the capacitor C, and the passive-type pin-diverging module  2  includes a base structure  20  and a rotatable structure  21 . In addition, the rotatable structure  21  is rotatably disposed on the base structure  20 , and the rotatable structure  21  has a curved surface  2100 . 
     More particularly, the rotatable structure  21  includes a pivot axle  211  detachably connected between the first pivot seat  2012  and the second pivot seat  2022  and a pivot ball  213  disposed between the first pivot seat  2012  and the second pivot seat  2022  and pivotably disposed around the pivot axle  211 . In addition, the curved surface  2100  may be a spherical surface  2130  of the pivot ball  213 , and the two lateral contact surfaces P 10  of the two conductive pins P of the capacitor C can concurrently slidably contact the spherical surface  2130  of the pivot ball  213  for diverging the two conductive pins P so as to make the two conductive pins P incline toward a bottom side of the seat board B by a predetermined angle θ, so that the seat board B can be held by the two diverged conductive pins P so as to prevent the seat board B from being separated from the capacitor C. Please note, the friction resistance between the conductive pin P and the pivot ball  213  can be decreased due to the sliding contact between the lateral contact surface P 10  of the conductive pin P and the spherical surface  2130  of the pivot ball  213 . More precisely, the friction resistance between the conductive pin P and the pivot ball  213  is decreased, so that the reaction force applied to the two conductive pins P and the capacitor C due to the sliding contact between the lateral contact surface P 10  and the spherical surface  2130  can be decreased (or the structural variation of a junction between the conductive pin P and the capacitor C can be decreased, and an outer force applied to an inner structure of the capacitor C can be decreased). Therefore, the capacitor C provided by the instant disclosure can avoid increasing leakage current (LC) and causing a short circuit. 
     Third Embodiment 
     Referring to  FIG. 11  and  FIG. 12 , the third embodiment of the instant disclosure provides a passive-type pin-diverging module  2  for diverging the two conductive pins P of the capacitor C, and the passive-type pin-diverging module  2  includes a base structure  20  and a rotatable structure  21 . In addition, the rotatable structure  21  is rotatably disposed on the base structure  20 , and the rotatable structure  21  has a curved surface  2100 . 
     More particularly, the rotatable structure  21  includes a rotatable ball  214 . In addition, the curved surface  2100  may be a spherical surface  2140  of the rotatable ball  214 , and the two lateral contact surfaces P 10  of the two conductive pins P of the capacitor C can concurrently slidably contact the spherical surface  2140  of the rotatable ball  214  for diverging the two conductive pins P so as to make the two conductive pins P incline toward a bottom side of the seat board B by a predetermined angle θ, so that the seat board B can be held by the two diverged conductive pins P so as to prevent the seat board B from being separated from the capacitor C. Please note, the friction resistance between the conductive pin P and the rotatable ball  214  can be decreased due to the sliding contact between the lateral contact surface P 10  of the conductive pin P and the spherical surface  2140  of the rotatable ball  214 . More precisely, the friction resistance between the conductive pin P and the rotatable ball  214  is decreased, so that the reaction force applied to the two conductive pins P and the capacitor C due to the sliding contact between the lateral contact surface P 10  and the spherical surface  2140  can be decreased (or the structural variation of a junction between the conductive pin P and the capacitor C can be decreased, and an outer force applied to an inner structure of the capacitor C can be decreased). Therefore, the capacitor C provided by the instant disclosure can avoid increasing leakage current (LC) and causing a short circuit. 
     Fourth Embodiment 
     Referring to  FIG. 13 , the fourth embodiment of the instant disclosure provides a capacitor detection system S, comprising: a pin-flattening module  1 , a passive-type pin-diverging module  2 , a pin-positioning module  3 , and an electrical performance testing module  5 . Comparing  FIG. 13  and  FIG. 1 , the difference between the fourth embodiment and the first embodiment is as follows: the fourth embodiment of the capacitor detection system S further comprises a heat-generating module  4  disposed between the pin-positioning module  3  and the electrical performance testing module  5 , and the heat-generating module  4  can provide a predetermined heat source to the capacitor C so as to release stresses in the capacitor C. The stresses in the capacitor C are generated by the reaction force that is applied to the two conductive pins P and the capacitor C due to the sliding contact between the lateral contact surface P 10  and the curved surface  2100 . For example, the heat-generating module  4  may be a hot air generator, an infrared generator, or an ultraviolet generator for generating the predetermined heat source. 
     In conclusion, the two lateral contact surfaces P 10  of the two conductive pins P of the capacitor C can concurrently slidably contact the curved surface  2100  of the rotatable structure  21  so as to diverge the two conductive pins P of the capacitor C, so that the seat board B can be held by the two diverged conductive pins P so as to prevent the seat board B from being separated from the capacitor C. Please note, the friction resistance between the conductive pin P and the rotatable structure  21  can be decreased due to the sliding contact between the lateral contact surface P 10  of the conductive pin P and the curved surface  2100  of the rotatable structure  21 . More precisely, the friction resistance between the conductive pin P and the rotatable structure  21  is decreased, so that the reaction force applied to the two conductive pins P and the capacitor C due to the sliding contact between the lateral contact surface P 10  and the curved surface  2100  can be decreased (or the structural variation of a junction between the conductive pin P and the capacitor C can be decreased, and an outer force applied to an inner structure of the capacitor C can be decreased). Therefore, the capacitor C provided by the instant disclosure can avoid increasing leakage current (LC) and causing a short circuit.
