And it takes a long time, and there is a problem that only skilled professionals have no choice but to perform the work.

In addition, since the upper conductor is connected to the electrode terminal while the upper conductor is simply lowered on the lower conductor according to the rotation of the adjusting bolt, if there is a manufacturing error or the degree of rotation of the adjusting bolt is different, the electrical resistance value increases due to the non-uniform connection and conducts electricity There is a problem in that the efficiency is lowered, and heat generation and damage to the electrode terminal occur.

The present invention is a secondary battery fixing jig used when performing a charging/discharging process or test of a secondary battery, and FIGS. 1 to 8 illustrate a secondary battery fixing jig according to an embodiment of the present invention.

First, as illustrated in FIG. 1 , the secondary battery fixing jig (hereinafter, abbreviated as “jig”) according to an embodiment of the present invention includes a terminal connection part 10 and a jig frame 30. can be done

The jig frame 30 is a part on which the secondary battery B is seated and mounted on the upper surface, and the terminal connection part 10 is provided on the jig frame 30 and is an electrode terminal (t) of the mounted secondary battery (B). It is a part that electrically connects the power supply for charging, the load for discharging, or the terminal for measurement by being connected to

The jig frame 30 may be formed in a substantially rectangular shape so as to be inserted into the chamber for the charge/discharge process of the secondary battery (C).

The jig frame 30 may have a rail groove 31 extending in the front-rear direction on the upper surface. Position adjustment can be made by moving the terminal connection part 10 back and forth along the rail groove 31 in a seated state or seated in the rail groove 31 .

A connector terminal block 32 may be provided at one end of the jig frame 30 to simply connect a cable for power application, and the connector terminal block 32 is electrically connected to a terminal connection portion 10 to be described later. can be connected

The terminal connection part 10 is provided at least one or more on the upper surface of the end of the jig frame 30, the position and number provided according to the electrode terminal arrangement structure of the secondary battery mounted on the jig frame 30 can be set. have.

For example, in the case of a unidirectional secondary battery in which the electrode terminal is formed in only one direction, the terminal connection part 10 may be provided as a pair only at one end of the jig frame 30, and when the electrode terminal is a bidirectional secondary battery formed in both directions The terminal connection part 10 may be provided at both ends of the jig frame 30 to face each other.

In addition, in the case of a secondary battery that is universally used for a unidirectional or bidirectional secondary battery or the electrode terminal is formed to be biased to one side rather than the center, as illustrated in FIG. 1 , the terminal connection part 10 is at one end of the jig frame 30 . Along with being provided as a pair, it may be additionally provided on the other end.

Hereinafter, the configuration of the terminal connection unit 10 will be described in more detail with reference to FIGS. 2 to 6 .

As illustrated in FIGS. 2 to 6 , the terminal connection part 10 may include a lower conductive block 100 and an upper conductive block 200 , and a rotation clamp 300 .

First, the lower conductive block 100 and the upper conductive block 200 are elements corresponding to each other, and may be connected to the electrode terminal t of the secondary battery B to conduct electricity.

That is, the lower conductive block 100 is located below the electrode terminal t and is closely connected to the bottom surface of the electrode terminal t, and in response to this, the upper conductive block 200 is located on the upper side of the electrode terminal t. By being positioned on the electrode terminal (t) can be closely connected to the upper surface.

The lower conductive block 100 and the upper conductive block 200 may each include a block body having a supporting function and a conductive plate having a current conducting function, and may be disposed in a vertical symmetrical structure with each other.

That is, the lower conductive block 100 includes a lower block body 110 and a lower conductive plate 120 supported on the upper surface of the lower block body 110, and the upper conductive block 200 is an upper block body ( 210) and an upper conductive plate 220 supported on the bottom surface of the upper block body 210 may be included.

The lower conductive plate 120 and the upper conductive plate 220 may be electrically connected to the bottom and top surfaces of the electrode terminal t by being in close contact with each other.

The lower conductive plate 120 and the upper conductive plate 220 may be elastically supported by the lower block body 110 and the upper block body 210, respectively.

That is, as illustrated in FIG. 6 , the lower conductive plate 120 may be coupled to the upper surface of the lower block body 110 to receive elastic force upward through the vertical elastic body 111 , and the upper conductive plate 220 . may be coupled to the bottom surface of the upper block body 210 to receive an elastic force downward through the vertical elastic body 211 .

As above, the lower conductive plate 120 and the upper conductive plate 220 are elastically supported upward and downward by the lower block body 110 and the upper block body 210, respectively, so that the lower conductive plate 120 and the upper conductive plate ( 220) can be elastically and airtightly adhered to the bottom and upper surfaces of the electrode terminals t, respectively, and improvement in energization efficiency can be expected by such airtight adhesion.

In addition, a connecting leg 140 for connecting the cable (c) may be further formed on the lower conductive block 100 .

The connecting leg 140 may extend from the lower surface of the lower conductive plate 120 to penetrate the lower block body 110 to protrude downwardly of the lower block body 110 .

The connecting leg 140 may be formed with a coupling groove 141 for easily connecting the cable c by fitting it.

In addition, the upper conductive block 200 may be provided with a voltage sensor (not shown) for sensing the voltage applied to the electrode terminal (t).

In the lower conductive block 100 and the upper conductive block 200 having the above configuration, the position of the lower conductive block 100 is fixed in the vertical direction so as not to flow up and down, and the upper conductive block 200 is vertically It may be configured to be movable without being fixed in the direction.

Here, the upper conductive block 200 may flow in a vertical direction while rotating, unlike a conventional method in which the upper conductive block 200 moves in a straight line vertically, that is, while moving up and down.

The rotation of the upper conductive block 200 may be made by a rotation clamp 300 to be described later. That is, the upper conductive block 200 may be rotated in the vertical direction according to the operation of the rotation clamp 300 .

As the upper conductive block 200 is configured to be rotatable up and down in this way, the upper conductive block 200 has an electrode terminal (t) set in the terminal connection part 10 for a charge/discharge process or an electrode terminal ( When t) is separated from the terminal connection part 10 , it rotates upward, and during the charging/discharging process, it can be rotated downward so as to be in close contact with the electrode terminal t set seated on the lower conductive block 100 .

Here, when the electrode terminal t is set to be seated on the lower conductive block 100, the upper conductive block 200 is rotated upward so that the upper part of the lower conductive block 100 is in an empty space. ) of the connection terminal unit 10 can be set more simply and quickly.

In addition, the lower conductive block 100 is fixed in the vertical direction, the position is not fixed in the front and rear horizontal direction, it may be possible to move forward and backward at a predetermined interval.

Furthermore, the lower conductive block 100 maintains a state advanced by a predetermined interval (d) forward from the alignment point (P) in a state in which the upper conductive block 200 is rotated upward, and the upper conductive block 200 is close to each other. When it is rotated, the position can be adjusted to the alignment point P by being pressed by the upper conductive block 200 and moved backward.

Here, the 'alignment point (P)' refers to a point at the same position between the lower conductive block 100 and the upper conductive block 200 when viewed in the vertical direction, that is, a point where the upper and lower positions are aligned.

That is, when the upper conductive block 200 is rotated downward and is horizontally in close contact with the electrode terminal t, the lower conductive block 100 and the upper conductive block 200 are aligned with the electrode terminal t interposed therebetween. In (P), the positions can be matched up and down.

In other words, as illustrated in FIG. 3 , initially the lower conductive block 100 is positioned in a state advanced by a predetermined interval (d) forward from the alignment point (P).

In this state, when the electrode terminal t is seated on the lower conductive block 100 and then the upper conductive block 200 is rotated downward to reach a close position, as illustrated in FIG. 4 , the upper conductive block 200 ), the backward movement is started, and as illustrated in FIG. 5 , when the upper conductive block 200 is horizontally rotated so as to be in close contact with the upper surface of the electrode terminal t, the lower conductive block 100 ) Also, as the backward movement is completed, the upper conductive block 200 is positioned at a position that coincides with the upper and lower sides, that is, the alignment point (P).

In order to adjust the position of the lower conductive block 100 , the pressed protrusion 130 may be formed in the lower conductive block 100 , and a pressing end 230 may be formed in the upper conductive block 200 in response thereto.

The pressed protrusion piece 130 is formed to protrude upward at a predetermined height from the rear end of the lower conductive block 100 , and the pressing end 230 is formed at the rear end of the upper conductive block 200 to form the upper conductive block 200 . As it rotates, when it reaches a certain angle close to the lower conductive block 100, it is caught by the protrusion to be pressed 130 and then presses the protrusion to be pressed 130 to the rear according to the rotation.

In addition, when the pressure by the upper conductive block 200 is released, the lower conductive block 100 is advanced by a predetermined interval (d) forward from the alignment point (P) and is supported on the horizontal elastic body 150 so that it is automatically returned to the initial position. An elastic force may be provided in the forward direction.

That is, the horizontal elastic body 150 is compressed when the lower conductive block 100 is pressed to the upper conductive block 200 and moved backward to the alignment point P, and then the upper conductive block 200 is rotated upward to release the pressure. This is to provide a forward elastic force to the lower conductive block 100 so that the lower conductive block 100 returns to its original position in front of the alignment point P while being restored.

As above, as the lower conductive block 100 is automatically positioned in connection with the rotation of the upper conductive block 200, the lower conductive block 100 and the upper conductive block 200 are aligned so that the upper and lower positions of the electrodes are aligned. A close connection can be made to the bottom and top surfaces of the terminal t in the same area, and through this, excellent conduction efficiency can be provided.

The rotation clamp 300 is a portion that provides a rotation force to the upper conductive block 200 . That is, the upper conductive block 200 may be rotated in the vertical direction by the operation of the rotation clamp 300 .

The rotation clamp 300 may include a clamp body 310 , an operation lever 320 , and a rotation arm 330 .

The clamp body 310 is fixedly positioned on the rear side of the lower conductive block 100 and may be erected at a predetermined height.

One end of the operation lever 320 is shaft-coupled to the clamp body 310 to be rotatable, and a handle 321 may be formed at the other end.

One end of the pivot arm 330 may be axially coupled to the upper end of the clamp body 310 , and may be link-coupled to the operation lever 320 through a connection link 331 .

The rotating arm 330 may extend to a predetermined length, and the upper conductive block 200 may be coupled and fixed to a lower portion thereof.

According to this configuration, when the user rotates the operation lever 320 by holding the handle 321, the rotation arm 330 and the upper conductive block 200 coupled thereto are rotated up and down.

On the other hand, the terminal connection unit 10 having the above configuration may further include a base plate 400 provided on the bottom surface of the lower conductive block 100 according to an embodiment.

When the base plate 400 is provided, the lower conductive block 100 can be adjusted forward and backward in a state supported by the base plate 400, and the clamp body 310 of the rotating clamp 300 is the base. It may be fixed to the upper surface of the plate 400 .

An opening 410 of a predetermined size may be formed in the base plate 400 so that the connecting leg 140 does not interfere when the lower conductive block 100 is moved forward and backward.

In addition, the base plate 400 may have an extension end 420 extending to protrude a predetermined length forward from the lower conductive block 100 .

A fastening groove 421 may be formed in the extension end 420 to seat and couple the space block s on the upper surface.

The space block (s) is a block body supporting the electrode terminal (t) to prevent the electrode terminal (t) from being deformed or damaged, and may be selectively selected according to the structure and shape of the electrode terminal (t). The extension end 420 of the base plate 400 may be coupled and installed on the upper surface.

As described above with respect to the fixing jig according to an embodiment of the present invention, the secondary battery (B) is mounted and set in the fixing jig of the present invention with reference to FIGS. 7 to 8 together with the above drawings. Let's take a brief look at the process.

At this time, it is assumed that the secondary battery B to be charged/discharged is a bidirectional secondary battery in which the electrode terminal t is formed at both ends of the front and rear ends. take as an example

First, as illustrated in FIG. 7 , the upper conductive block 200 of the terminal connection part 10 is rotated upward by the operation lever 320 to maintain a state spaced apart from the lower conductive block 100 .

The lower conductive block 100 is positioned forward by a predetermined interval d from the alignment point P by the elastic force provided from the horizontal elastic body 150 .

In addition, in the base plate 400 of the terminal connection part 10, a space block (s) having an appropriate height and size is selected to support and support the electrode terminal (t) corresponding to the structure of the secondary battery (B) to be mounted. become and combine

That is, as illustrated in FIG. 7 , the space block s may be seated and coupled to the extension end 420 of the base plate 400 in advance.

In addition, as illustrated in FIG. 7 , the terminal connection part 10 provided on the rear side is connected through a cable c to have the same polarity as one of the pair of terminal connection parts 10 provided on the front side.

At this time, the cable (c) may be coupled to the connecting red 140 of each of the front and rear terminal connection parts 10 and connected, so that the cable (c) is directly connected to each other at the lower side of the terminal connection part 10 . Since it is arranged to be connected, the connection operation of the cable (c) can be made simply, and the interference problem according to the arrangement path of the cable (c) does not occur at all.

In this initial state, the secondary battery B is seated on the upper surface of the jig frame 30 and mounted, and the electrode terminal t is set to be connected to the terminal connection part 10 .

Looking at this setting process in more detail, the electrode terminal t of the secondary battery B is seated on the upper surface of the lower conductive block 100 .

At this time, as illustrated in FIG. 7 , the upper conductive block 200 is rotated upward so that the upper portion of the lower conductive block 100 is an empty space without an interfering structure, so the electrode terminal of the secondary battery B (t) can be placed directly on the lower conductive block 100 simply and quickly.

That is, in the conventional terminal connection structure, it is impossible to directly seat the electrode terminal of the secondary battery from the upper side to the lower side as in the present invention due to the structure on the upper side including the upper conductor and the adjusting bolt. It was necessary to set the electrode terminals in such a way that the prepared terminal connection part was moved backward at a certain interval and then moved forward again after being seated. There was a problem that the (Loss) space had to exist.

On the other hand, in the present invention, since the electrode terminal t of the secondary battery B can be directly seated from the upper side on the lower conductive block 100 through the rotating structure, there is no need to provide an unnecessary space in the jig frame 30 . With none, it is possible to set the electrode terminal t to the terminal connection part 10 more simply and quickly.

As above, when the electrode terminal t is seated on the lower conductive block 100 while the secondary battery B is mounted on the jig frame 30, the operation lever 320 is then gripped and rotated forward.

Then, as the rotation arm 330 coupled to the link rotates downward according to the rotation of the operation lever 320, the upper conductive block 200 coupled to and supported by the rotation arm 330 is also rotated.

When the upper conductive block 200 reaches a certain angle close to the lower conductive block 100 in this rotation process, the pressing end 230 of the upper conductive block 200 is pressed by the lower conductive block 100 as described above. As it meets the stone piece 130, the jamming occurs.

And when the rotation is continued, the pressed protrusion piece 130 is pressed toward the rear by the pressing end 230, and accordingly, the backward movement of the lower conductive block 100 starts, and finally the upper conductive block 200. When the horizontal rotation is completed, the lower conductive block 200 also completes the backward movement, and the lower conductive block 100 and the upper conductive block 200 are connected to the electrode terminal t at the alignment point P. do.

At this time, the lower conductive block 100 and the upper conductive block 200 are connected while the lower conductive plate 120 and the upper conductive plate 220 are in elastic contact with the bottom and top surfaces of the electrode terminal t, respectively. will lose

In this way, in a state in which the lower conductive block 100 and the upper conductive block 200 are aligned with each other to match the positions of the lower and upper surfaces of the electrode terminal t, elastically and uniformly and stably adhere to each other, so that the conduction efficiency is improved. Damage to the electrode terminal (t) can be effectively prevented along with a significant improvement.

Through the above process, the setting of the secondary battery t can be easily and quickly completed, and thereafter, a charging/discharging process can be performed by connecting a cable to the connector terminal block 32 and applying power.

As described above, it can be seen that, according to the fixing jig of the present invention, since the terminal connection part has a rotating structure, the setting operation for connection of the electrode terminal can be performed simply and quickly.

In addition, it can be seen that the electrode terminal part is not a complicated structure as in the prior art, but has a relatively simple configuration such as a lower conductive block, an upper conductive block, and a rotation clamp, so that it can be easily manufactured.

In addition, since the lower conductive block and the upper conductive block are elastically closely aligned so that their positions are precisely aligned, the electrode terminals are connected and energized stably and uniformly. It can be seen that this can be done more efficiently.

The preferred embodiments of the present invention have been described in detail above, but the technical scope of the present invention is not limited to the contents described in the above-described embodiments and drawings, and may be modified or modified by those of ordinary skill in the art. It will be said that the changed equivalent configuration does not depart from the scope of the technical spirit of the present invention.
