Description
Technical Field
The present invention relates to the field of supercapacitors, and more particularly, to a connector for a lead-type supercapacitor.
In the present specification, the term "supercapacitor" is a "supercapacitor" in a general sense, and also includes "lithium ion capacitor (LIC; lithum Ion Capacitor)".
Background
A capacitor is a device for accumulating electric energy. The unit of charge capacity accumulated in such a capacitor is farad (F). However, conventional capacitors, that is, general capacitors manufactured by interposing a dielectric between two opposing electrodes, have a limitation in that the storable charge capacity is extremely small in μf or pF units. In this regard, super capacitors (super capacitors) have been developed in which the charge capacity is extremely large, and the unit of the charge capacity can be represented by F, for example. As described above, the super capacitor is a capacitor having extremely large electrostatic capacity, and is called an "ultra capacitor". The super capacitor uses active carbon with large surface area, shortens the distance of dielectric medium, can obtain the extremely large electrostatic capacity of F unit in miniaturization, does not have bad influence on service life even if overcharging and overdischarging, and has the advantage of environmental protection.
Above-mentioned supercapacitor generally uses simple structure's lead wire type supercapacitor, and lead wire type supercapacitor includes: a body for storing an electric charge; and two pins (leader pins) extending from one side of the body in one direction, having different polarities, i.e., having polarities of an anode and a cathode.
Conventionally, as a method for mounting a supercapacitor on a printed circuit board (PCB, printed Circuit Board), as shown in fig. 17, a method of bending first and second polarity pins at right angles and soldering the bent first and second polarity pins on the printed circuit board has been mainly used. However, this conventional method has problems in that it is difficult to reliably mount the supercapacitor on the printed circuit board, the soldering process is troublesome and inconvenient, and the capability of receiving external forces such as vibration is weak. Moreover, the above manner can only apply heat to the body of the supercapacitor during the welding process, and the heat applied above will reduce the performance of the supercapacitor.
As another alternative supercapacitor mounting method, as shown in fig. 18, a male connector is provided to a supercapacitor, and a female connector into which the male connector is inserted is provided on the printed circuit board side so that the male connector is inserted into and coupled to the female connector. Although this method is excellent in reliability, it has a problem of poor economical efficiency due to an increase in the number of components caused by the addition of the male connector or the like, and an increase in the number of steps such as the production of the male connector and the additional processing of a plurality of pins for coupling with a plurality of terminals of the male connector.

According to one embodiment, a first groove and a second groove are formed on both sides of an upper surface of the housing with respect to a linear center portion, and the first elastic coupling piece and the second elastic coupling piece are respectively fixed to the first groove and the second groove so as to face the first insertion hole and the second insertion hole, and when moving from the unlocking position to the locking position, the push cover applies downward pressure to the first elastic coupling piece and the second elastic coupling piece by the first pressing protrusion and the second pressing protrusion.
According to one embodiment, the length of the first polar pin is smaller than the length of the second polar pin, the first insertion hole and the first elastic coupling piece protrude forward with respect to the second insertion hole and the second elastic coupling piece, respectively, so as to compensate for a difference in length between the first polar pin and the second polar pin, the front portion of the housing includes a first front portion and a second front portion, the first front portion is formed with the first insertion hole and protrudes forward, the second front portion is formed with the second insertion hole and is located rearward, and a distance from a virtual plane including the first front portion to the first elastic coupling piece is smaller than the length of the first polar pin, and a distance from a virtual plane including the first front portion to the second elastic coupling piece is greater than the length of the first polar pin and smaller than the length of the second polar pin.
The invention does not utilize a troublesome, inefficient and uneconomical welding manner, but can directly insert the first polarity pin and the second polarity pin of the supercapacitor into the connector of the printed circuit board to mount the supercapacitor. The invention has the advantages that the installation process of the super capacitor is simple and easy, reliable installation can be realized, and the super capacitor has strong bearing capacity to vibration or external impact. Further, the present invention can prevent a short circuit phenomenon caused by leakage of the electrolyte.

Referring to fig. 1 to 5, there can be seen a connector 1 for a lead type supercapacitor according to a first embodiment of the present invention mounted on a printed circuit board (not shown) for mounting a lead type supercapacitor 10 on the printed circuit board.
As shown in fig. 1 to 5, the lead type super capacitor 10 may be an electric double layer capacitor (EDLC; electric Double Layer Capacitor), a lithium ion capacitor (LIC: lithium Ion Capacitor), or the like, which includes: a body 12 for storing electric charges; and a first polarity pin 14a and a second polarity pin 14b extending from the main body 12 in a straight direction. In the present embodiment, the first polarity pins 14a and the second polarity pins 14b extend in parallel in one direction, and have the same length.
In this specification, the first polarity and the second polarity may be an anode or a cathode.
The lead wire type supercapacitor connector 1 (hereinafter referred to as "connector") includes: the housing 100 having a first insertion hole 114a and a second insertion hole 114b for allowing the first polarity pin 14a and the second polarity pin 14b to pass therethrough; the first and second terminal frames 200a and 200b are integrally coupled to the housing 100, and are formed with first and second elastic coupling pieces 220a and 220b, and the first and second elastic coupling pieces 220a and 220b are inserted with the first and second polarity pins 14a and 14b passing through the first and second insertion holes 114a and 114b; and a locking means for elastically deforming the first elastic coupling piece 220a and the second elastic coupling piece 220b in a state where the first polar pin 14a and the second polar pin 14b are inserted into the first elastic coupling piece 220a and the second elastic coupling piece 220b, so as to lock the first polar pin 14a and the first elastic coupling piece 220a and the second polar pin 14b and the second elastic coupling piece 220b which are coupled to each other.
The first insertion hole 114a and the second insertion hole 114b are formed in a front surface of the housing 100. The front surface of the cover 100 is formed of an upper concave front surface 2 and a lower convex front surface 4, and the first insertion hole 114a and the second insertion hole 114b are formed so as to share the concave front surface 2 and the convex front surface 4. The protruding front portion 4 includes a step 41 having a shape similar to a triangle at an upper end thereof, that is, a pair of symmetrically inclined surfaces, and the first insertion hole 114a and the second insertion hole 114b are formed to overlap on the step 41, whereby a worker can easily insert the first polarity pin 14a and the second polarity pin 14b into the first insertion hole 114a and the second insertion hole 114b in a state that the first polarity pin 14a and the second polarity pin 14b are supported on the step 41.
In the protruding front surface portion 2, the separation wall 6 is formed to be long from the top to the bottom so as to block the space between the first insertion hole 114a and the second insertion hole 114b. In a state where the first and second polarity pins 14a and 14b of the supercapacitor 10 are coupled to the first and second elastic coupling pieces 220a and 220b, respectively, leakage of the electrolyte may occur through the first and second insertion holes 114a and 114b, and in this case, the protruding front portion 4 prevents leakage flow for the first time, and even if the leakage flows along the surface of the protruding front portion 4, the separation wall 6 is blocked, so that a short circuit due to leakage of the electrolyte may be prevented.
A pair of grooves 124a and 124b, that is, a first groove 124a and a second groove 124b, are formed on the left and right sides of the upper surface of the housing 100 with respect to the linear center 121, and the first elastic coupling piece 220a of the first coupling terminal and the second elastic coupling piece 220b of the second coupling terminal coupled to and supported by the housing 100 face the first insertion hole 114a and the second insertion hole 114b in a state of being fixed to the first groove 124a and the second groove 124b, respectively. The first and second connection terminals are formed by cutting and bending a metal sheet, and the first and second elastic connection pieces 220a and 220b are integrally formed at an upper portion thereof, and first and second electrode pieces coupled to first and second electrodes of a printed circuit board (not shown) are formed at a lower portion thereof.
The first elastic coupling piece 220a and the second elastic coupling piece 220b have a groove structure surrounding the first polar pin 14a and the second polar pin 14b to allow the first polar pin 14a and the first polar pin 14b to be inserted, and pressing plate portions 222a and 222b for pressing the first polar pin 14a and the second polar pin 14b by an external force are integrally formed at the upper end.
On the other hand, the above-mentioned locking unit includes: a pair of guide grooves 130, 130 formed in a vertically long manner on both side surfaces of the housing 100; and a push cover 300 which is lowered from a lock release position to a lock position along the guide grooves 130, and presses down the pressing plate portions 222a, 222b of the first elastic coupling piece 220a and the second elastic coupling piece 220b in the lock position, thereby elastically deforming the first elastic coupling piece 220a and the second elastic coupling piece 220 a.
The push cover 300 includes: a block-shaped body 320 spaced apart from the first elastic coupling piece 220a and the second elastic coupling piece 220b in the unlocking position, and elastically deforming by pressing the first elastic contact piece 220a and the second elastic coupling piece 220b downward in the locking position; and a pair of bracket parts 340 and 340 extending downward in a state of being formed at both side ends of the main body part 320, and guided in the pair of guide grooves 130. In this case, a pair of pressing protrusions 322a and 322b, that is, a first pressing protrusion 322a and a second pressing protrusion 322b, are formed on the bottom surface of the main body 320 so as to enter the first groove 124a and the second groove 124b from the locking position and press the first elastic coupling piece 220a and the second elastic coupling piece 220b downward. Further, the upper engagement groove 342 and the lower engagement groove 344 are formed in a zigzag shape on the inner surfaces of the pair of bracket portions 340.
An engagement step 134 is formed in the inner surface of the guide groove 130 to engage with the lower engagement groove 344 in the unlocking position, and to engage with the upper engagement groove 342 in the locking position. The engagement step 134 has a structure including an upper gentle slope and a lower steep slope with respect to the apex. The upper engagement groove 342 and the lower engagement groove 344 have a structure in which a gently inclined surface and a steeply inclined surface intersect with each other. The push cover 300 is lowered from the lock release position to the lock position such that the engagement between the lower engagement groove 344 and the engagement step 134 is released due to the elastic deformation accompanying the holder portion 340 of the push cover 300, and instead, the upper engagement groove 342 engages with the engagement step 134, thereby completely restricting the movement of the push cover 300 in the lock position. In this state, the push cover 300 strongly presses the first and second elastic coupling pieces 220a and 220b to maintain a state of pressing the first and second polarity pins 14a and 14b, and thus, the first polarity pin 14a and the first elastic coupling piece 220a coupled to each other and the second polarity pin 14b and the second elastic coupling piece 220b coupled to each other can be reliably locked. In this case, holes 345 are formed at the bracket parts 340, respectively, to help the bracket parts 340 elastically deform during the period in which the locking between the lower locking groove 344 and the locking step 134 is released.
Referring to fig. 6 to 10, there can be seen a connector 1 for a lead type supercapacitor according to a second embodiment of the present invention mounted on a printed circuit board (not shown) for mounting the lead type supercapacitor 10 on the printed circuit board.
As in the above embodiment, the lead type super capacitor 10 may be an electric double layer capacitor (EDLC; electric Double Layer Capacitor), a lithium ion capacitor (LIC: lithium Ion Capacitor), or the like, which includes: a body 12 for storing electric charges; and first and second polarity pins 14a and 14b extending in the lateral direction from one side surface of the main body 12.

The first insertion hole 114a and the second insertion hole 114b are formed in a front surface of the housing 100. Although not shown, a structure for preventing leakage of the electrolyte solution of the above embodiment, that is, a structure including a protruding front face portion, a recessed front face portion, and/or a separation wall may be applied to the front face portion of the housing 100, and, although not shown, the protruding front face portion may include a step having a shape similar to a triangle at an upper end, that is, including a pair of symmetrically inclined surfaces, the first insertion hole 114a and the second insertion hole 114b may be formed to overlap on the step, whereby a worker may easily insert the first polarity pin 14a and the second polarity pin 14b into the first insertion hole 114a and the second insertion hole 114b in a state of supporting the first polarity pin 14a and the second polarity pin 14b on the step 41.
A pair of grooves 124a and 124b, that is, a first groove 124a and a second groove 124b, are formed on the left and right sides of the upper surface of the housing 100 with respect to the linear center 121, and the first elastic coupling piece 220a of the first coupling terminal and the second elastic coupling piece 220b of the second coupling terminal coupled to and supported by the housing 100 face the first insertion hole 114a and the second insertion hole 114b in a state of being fixed to the first groove 124a and the second groove 124b, respectively.

The first elastic coupling piece 220a and the second elastic coupling piece 220b have a hole structure surrounding the first polar pin 14a and the second polar pin 14b to allow the first polar pin 14a and the first polar pin 14b to be inserted, and a cut-out portion 225 for opening the hole structure to an upper side is formed at an upper end thereof.
On the other hand, the above-mentioned locking unit includes: a pair of guide grooves 140 formed in a longitudinal direction on both side surfaces of the housing 100; and a push cover 300 moving from a lock release position to a lock position along the guide groove 140, wherein the first elastic coupling piece 220a and the second elastic coupling piece 220a are elastically deformed by pressing down the cut-out portion 225 of the first elastic coupling piece 220a and the second elastic coupling piece 220b and the periphery thereof in the lock position.
The push cover 300 includes: a flat plate-shaped main body 320 that is separated from the first elastic coupling piece 220a and the second elastic coupling piece 220b in the locked position, that is, in the backward position, and that is, in the forward position, presses down the first elastic coupling piece 220a and the second elastic coupling piece 220b upward and downward to elastically deform the first elastic coupling piece 220a and the second elastic coupling piece 220b in the locked position, that is, in the forward position; and a pair of bracket parts 340 and 340 formed at both side ends of the main body part 320 and extending downward, and guiding forward and backward along the pair of guiding grooves 140.
In this case, a pair of pressing protrusions 322a and 322b, that is, a first pressing protrusion 322a and a second pressing protrusion 322b, are formed on the bottom surface of the main body 320 so as to enter the first groove 124a and the second groove 124b from the locking position and press the first elastic coupling piece 220a and the second elastic coupling piece 220b downward. In this case, the first and second pressing protrusions 322a and 322b may have tapered portions at portions thereof which contact the first and second elastic coupling pieces 220a and 220b when the first and second pressing protrusions 322a and 322b are advanced, so that the first and second pressing protrusions 322a and 322b are prevented from being caught by the first and second elastic coupling pieces 220a and 220b while the first and second pressing protrusions 322a and 322b are advanced so as to be placed on the first and second elastic coupling pieces 220a and 220b.
On the other hand, a hook portion 346 is formed at the lower end of the pair of bracket portions 340, which is caught at the upper portion of the guide groove 140, to prevent the push cover 300 from being separated upward. In addition, a pair of protrusion guide grooves 127a and 127b are formed on the upper surface of the housing 100 to guide the first and second pressing protrusions 322a and 322b to advance when the first and second pressing protrusions 322a and 322b enter the first and second grooves 124a and 124 b.
Referring to fig. 11 to 16, there can be seen a connector 1 for a lead type supercapacitor according to a third embodiment of the present invention mounted on a printed circuit board (not shown) for mounting the lead type supercapacitor 10 on the printed circuit board.
As in the above embodiment, the lead type super capacitor 10 may be an electric double layer capacitor (EDLC; electric Double Layer Capacitor), a lithium ion capacitor (LIC: lithium Ion Capacitor), or the like, which includes: a body 12 for storing electric charges; and first and second polarity pins 14a and 14b extending in the lateral direction from one side surface of the main body 12. In the present embodiment, the first polarity pin 14a and the second polarity pin 14b extend in parallel in one direction, and the length L1 of the first polarity pin 14a is smaller than the length L2 of the second polarity pin 14b.
The connector 1 includes: the housing 100 having a first insertion hole 114a and a second insertion hole 114b for allowing the first polarity pin 14a and the second polarity pin 14b to pass therethrough; a first terminal frame and a second terminal frame integrally coupled to the housing 100, and having a first elastic coupling piece 220a and a second elastic coupling piece 220b formed therein, wherein the first elastic coupling piece 220a and the second elastic coupling piece 220b are inserted with the first polarity pin 14a and the second polarity pin 14b passing through the first insertion hole 114a and the second insertion hole 114b; and a locking means for elastically deforming the first elastic coupling piece 220a and the second elastic coupling piece 220b in a state where the first polar pin 14a and the second polar pin 14b are inserted into the first elastic coupling piece 220a and the second elastic coupling piece 220b, so as to lock the first polar pin 14a and the first elastic coupling piece 220a and the second polar pin 14b and the second elastic coupling piece 220b which are coupled to each other.
In this case, the first insertion hole 114a and the first elastic coupling piece 220a protrude forward than the second insertion hole 114b and the second elastic coupling piece 220b to compensate for a difference in length between the first polarity pin 14a and the second polarity pin 14b.
The housing 100 includes a right first front surface 110a protruding forward and a left second front surface 110b recessed rearward. The first insertion hole 114a is formed in the first front surface 110a so as to protrude forward, and the second insertion hole 114b is formed in the second front surface 110b so as to be recessed rearward.
The first front surface 110a is formed of an upper first concave front surface 2a and a lower first convex front surface 4a, and the first insertion hole 114a is formed so as to share the first concave front surface 2a and the first convex front surface 4 a. The second front surface portion 110b is formed of an upper second concave front surface portion 2b and a lower second convex front surface portion 4b, and the second insertion hole 114b is formed so as to share the second concave front surface portion 2b and the second convex front surface portion 4b.
The first protruding front surface portion 4a and the second protruding front surface portion 4b are formed at upper ends thereof with steps 41a and 41b having inclined surfaces formed on one side, and the first insertion hole 114a and the second insertion hole 114b are formed to overlap with the steps 41a and 41b, whereby a worker can easily insert the first polarity pin 14a and the second polarity pin 14b into the first insertion hole 114a and the second insertion hole 114b in a state where the first polarity pin 14a and the second polarity pin 14b are supported by the steps 41a and 41 b.
In a state where the first and second polarity pins 14a and 14b of the supercapacitor 10 are coupled to the first and second elastic coupling pieces 220a and 220b, respectively, leakage of the electrolyte may be leaked through the first and second insertion holes 114a and 114b, and in this case, the first and second protruding front portions 4a and 4b may be prevented from flowing for the first time by a height difference of upper ends. Further, since the height difference is formed between the first front surface portion 110a and the second front surface portion 110b, there is no concern that the electrolyte flowing out from the first insertion hole 114a flows to the vicinity of the second insertion hole 114b to cause a short circuit or the electrolyte flowing out from the second insertion hole 114b flows to the first insertion hole 114a to cause a short circuit.
A pair of grooves 124a and 124b, that is, a first groove 124a and a second groove 124b are formed on the left and right sides of the upper surface of the housing 100 with respect to the linear center 121, the first groove 124a protruding forward by a distance that the first insertion hole 114a protrudes forward, and the second groove 124b recessed rearward by a distance that the second insertion hole 114b protrudes rearward.
The first groove 124a is fixedly provided with a first elastic coupling piece 220a of a first coupling terminal coupled to and supported by the housing 100 so as to face the first insertion hole 114a, and the second groove 124b is fixedly provided with a second elastic coupling piece 220b of a second coupling terminal coupled to and supported by the housing 100 so as to face the second insertion hole 114b. Therefore, the first elastic coupling piece 220a protrudes forward than the second elastic coupling piece 220b.
The first and second connection terminals are formed by cutting and bending a metal sheet, and the first and second elastic connection pieces 220a and 220b are integrally formed at an upper portion thereof, and first and second electrode pieces coupled to first and second electrodes of a printed circuit board (not shown) are formed at a lower portion thereof.
The first elastic coupling piece 220a and the second elastic coupling piece 220b have a hole structure surrounding the first polarity pin 14a and the first polarity pin 14b to allow the first polarity pin 14a and the first polarity pin 14b to be inserted, and a cut-out portion for opening the hole structure to an upper side may be formed at an upper end.
In this case, a shortest distance D1 from a virtual plane including the first front surface portion 110a facing the main body portion 10 of the supercapacitor to the first elastic coupling piece 220a is smaller than a length L1 of the first polarity pin 14a, and a distance D2 from a virtual plane including the second front surface portion 110b to the second elastic coupling piece 220b is larger than the length L1 of the first polarity pin 14a and smaller than the length L2 of the second polarity pin 14b. Therefore, only the first polarity pin 14a is allowed to be coupled with the first elastic coupling piece 220a, and the second polarity pin 14b is normally coupled with the second elastic coupling piece 220b, such that the abnormal coupling of the first polarity pin 14a with the second elastic coupling piece 220b and/or the coupling of the second polarity pin 14b with the first elastic coupling piece 220a is fundamentally prevented.
On the other hand, the above-mentioned locking unit includes: a pair of guide grooves 140 formed in a longitudinal direction on both side surfaces of the housing 100; and a push cover 300 that moves from the unlocking position to the locking position along the guide groove 140, and elastically deforms the first elastic coupling piece 220a and the second elastic coupling piece 220b by pressing down the first elastic coupling piece 220a and the second elastic coupling piece 220b in the locking position.
The push cover 300 includes: a flat plate-shaped main body 320 that is away from the first elastic coupling piece 220a and the second elastic coupling piece 220b in the unlock position, that is, in the backward position, and that is, in the forward position, presses the first elastic coupling piece 220a and the second elastic coupling piece 220b downward in the first elastic coupling piece 220a and the second elastic coupling piece 220b to elastically deform them; and a pair of bracket parts 340 formed at both side ends of the main body part 320 and extending downward, and guiding forward and backward along the pair of guide grooves 140.
In this case, a pair of pressing protrusions 322a and 322b, that is, a first pressing protrusion 322a and a second pressing protrusion 322b, are formed on the bottom surface of the main body 320 so as to enter the first groove 124a and the second groove 124b from the locking position and press the first elastic coupling piece 220a and the second elastic coupling piece 220b downward. The first pressing protrusion 322a is formed at a bottom surface of the body 320 to protrude forward than the second pressing protrusion 322b. Further, the first and second pressing protrusions 322a and 322b may have tapered portions at portions contacting the first and second elastic coupling pieces 220a and 220b when the first and second pressing protrusions 322a and 322b are advanced, so that the first and second pressing protrusions 322a and 322b are prevented from being caught by the first and second elastic coupling pieces 220a and 220b during the first and second pressing protrusions 322a and 322b are advanced so as to be placed on the first and second elastic coupling pieces 220a and 220b.
On the other hand, a hook portion 346 is formed at the lower end of the pair of bracket portions 340, which is caught at the upper portion of the guide groove 140, to prevent the push cover 300 from being separated upward. A rear end stopper 147 is formed at the rear end of the guide groove 140 so as to be in contact with the rear end surface of the holder 340 in the unlocking position and restrict the holder 340 in order to prevent the push cover 300 from being separated rearward, and a front end stopper 148 and an intermediate stopper 149 are formed at the front end and the middle of the guide groove 140 so as to be in contact with the front end surface of the holder 340 and the rear end surface of the holder 340 in the locking position and fix the push cover 300. For this reason, in the guide groove 140, the depth of the section to the rear end stop 147 and the intermediate stop 149 is smaller than the depth of the section to the front end stop 148 and the intermediate stop 149.
In addition, a pair of protrusion guide grooves 127a and 127b are formed on the upper surface of the housing 100 to guide the first and second pressing protrusions 322a and 322b to advance when the first and second pressing protrusions 322a and 322b enter the first and second grooves 124a and 124 b.
The present invention is not limited to the above-described embodiments, but may be modified to be implemented in various forms.
