Background
In general, secondary batteries can be charged and have a large capacity, and typical secondary batteries include nickel-cadmium batteries, nickel-metal hydride batteries, and lithium batteries. Among these secondary batteries, a pouch type (pouche type) having flexibility can be prepared, and in this case, there is an advantage in that the shape thereof is relatively free.
Such a secondary battery has a battery cell inside a battery bag, and is configured such that the battery cell is surrounded by a polymer-based external material corresponding to the bag, and thus, is configured of an electrode, the bag, and the battery cell, and is required to be connected to the electrode in order to perform charge and discharge or various tests during the manufacturing process.
As a conventional technology related to electrode connection of a battery pouch, there is disclosed an "electrode connection unit for preventing damage to an electrode" in korean patent laid-open publication No. 10-2130939, which was filed by the applicant of the present invention. As a unit for connecting to an electrode of a battery, the electrode connecting unit includes: a body; an electrode guide provided on the body so as to protrude toward an insertion side of the electrode and face each other, the electrode guide being provided on the insertion side of the electrode with an insertion guide portion, the insertion guide portion being bent so that a distance between the insertion guide portions increases as the distance increases toward a distal end, thereby guiding the insertion of the electrode; and a pogo pin connector provided to the body such that the pogo pin is pressed by the electrode inserted into the electrode lead and elastically supported by a tip of the electrode to be electrically connected to the electrode, the pogo pin being subjected to an elastic force to protrude in a direction forming a line with a direction in which the electrode is inserted into the electrode lead. Fixing holes for fixing the electrode guide to the body by fixing bolts are respectively formed at both sides of the electrode guide, accommodating grooves for accommodating the pogo pin connectors so as to be movable are formed between the fixing holes so as to be opened in the front-rear direction, and the electrodes are inserted into the accommodating grooves to be connected to the pogo pins.
However, since the electrode lead of the related art is made of metal and the receiving groove is formed to be opened back and forth to receive the pogo pin connector, the pogo pin connector is inevitably exposed due to such a structure, and thus the pogo pin connector is easily damaged by interference with an external object, and there is a problem that durability and connection reliability are deteriorated.
Further, the conventional pogo pin connector has a problem that the body is made of a conductive material, and when two pogo pin connectors corresponding to the number of electrodes of the battery are used, the four-wire method cannot be used due to non-insulation properties of the electrode leads and the pogo pins made of a metal material.
In addition, in the conventional art, since the electrode lead made of a metal causes noise when performing measurement through electrode connection of the battery, in order to prevent the noise, an insulating sheet is attached to the electrode lead and used, but this is troublesome and also causes problems such as easy breakage and contamination of the insulating sheet.
In addition, the prior art also has the problem of inconvenient maintenance and management such as partial separation and replacement caused by the structure of the body shaping.
