In the embodiment of the invention, as shown in fig. 1 to 5 to fig. 5, the button cell wire holder comprises an external connection component and a bottom shell component,
the external connection component comprises an insulating body 10, a first metal elastic structure 50, at least one first electrode metal connection area 13 and at least one second electrode metal connection area 14;
the insulating body 10 is provided with a battery conducting surface 11 and an external connection surface 12 which are arranged oppositely;
the battery conducting surface 11 is provided with the first metal elastic structure 50, and is used for electrically contacting an electrode of a button battery 40 when elastic compression occurs;

The insulating body 10 may be a circular plate or a square plate, and is not particularly limited. The first electrode metal connection area 13 is used for welding or abutting contact electric conduction of an electrode wire of an electric device, the electrode wire of the electric device may be a positive electrode wire or a negative electrode wire, and no limitation is imposed on the electrode wire, specifically for example, when the first electrode metal connection area 13 is electrically conducted with the positive electrode of the button cell 40, the positive electrode wire of the electric device is welded or abutting contact electric conduction with the button cell; when the first electrode metal connecting region 13 is electrically connected with the negative electrode of the button cell 40, the negative electrode wire of the electric device is welded or in contact with the button cell.
The shape of the metal bottom case main body 20 may correspond to that of the insulating body 10, so that the installation space 30 formed by the metal bottom case main body 20 and the insulating body 10 is more regular, for example, the metal bottom case main body 20 and the insulating body 10 are both configured as circular plates, so that the installation space 30 is adapted to the button cell 40 in a circular button shape. After the button cell 40 is installed in the installation space 30, one end surface of the button cell 40 abuts against the cell conduction surface 11, and one electrode of the button cell 40 is formed on the end surface, and the electrode may be a positive electrode or a negative electrode, which is not limited specifically. The purpose of the contact between the battery conducting surface 11 and the button cell 40 is to better fix the button cell 40, and therefore, the battery conducting surface 11 and the button cell 40 may be in direct contact or indirect contact, or only needs to be stably fixed in the installation space 30 when the button cell 40 is determined to be able to be good without contact. Preferably, the battery conducting surface 11 is insulated, and after the first metal elastic structure 50 is electrically connected with one electrode of the button battery 40, the first metal elastic structure is electrically connected with the first electrode metal connection region 13 through an internal trace of the insulating body 10.
The second electrode metal connection region 14 is used for welding or abutting contact electrical conduction of an electrode wire of an electrical device, and may be a positive electrode wire or a negative electrode wire, which is not limited herein, specifically for example, when the second electrode metal connection region 14 is electrically conducted with a positive electrode of the button cell 40, the positive electrode wire of the electrical device is welded or abutting contact electrical conduction therewith; when the second electrode metal connecting region 14 is electrically connected to the negative electrode of the button cell 40, the negative electrode wire of the electric device is welded or in contact therewith.
The metal bottom case body 20 is made of a conductive material such as stainless steel, and copper, nickel, tin or an alloy of these elements to maintain sufficient structural strength while being conductive.
After the button cell 40 is installed in the installation space 30, the positive electrode abuts against the first metal elastic structure 50 on the insulating body 10, the negative electrode abuts against the second metal elastic structure 24 on the metal bottom case main body 20, namely, the positive electrode of the button cell 40 can be electrically conducted with the first electrode metal connection area 13 on the insulating body 10, so that the positive electrode wire welded on the first electrode metal connection area 13 can be electrically conducted with the negative electrode of the button cell 40, the negative electrode of the button cell 40 can be electrically conducted with the second electrode metal connection area 14 on the insulating body 10, so that the negative electrode wire welded on the second electrode metal connection area 14 can be electrically conducted with the negative electrode of the button cell 40, and the button cell 40 and the electric equipment can form a current loop through the button cell wire seat.
Because the positive pole line and the negative pole line of the electric equipment can be welded on the insulating body 10, the connection difficulty of the electric equipment and the button cell 40 can be further reduced, and the connection efficiency and the connection strength can be improved. Compared with the traditional method for welding two end faces of a button cell, the method can be used for directly welding one face, can be completed in one step particularly in the automatic welding process, improves the welding efficiency, and further, the first electrode metal connecting area 13 and the second electrode metal connecting area 14 on the insulating body 10 can be made of any conductive metal or non-metal material, preferably, the material is selected from copper, nickel, tin or alloy of the elements. The first electrode metal connection region 13 and the second electrode metal connection region 14 are used for electrode wire welding and conducting electricity, and copper, nickel and tin can reduce the connection difficulty during welding so as to further improve the welding efficiency.
In addition, when the button cell 40 is replaced, the electrode wire does not need to be operated, and only the button cell 40 needs to be disassembled and assembled, so that the replacement efficiency of the button cell 40 is further improved.
Further, in order to facilitate welding, the first electrode metal connection region 13 and the second electrode metal connection region 14 are disposed at adjacent positions on the same side, so that automatic welding is facilitated, that is, welding of a positive electrode wire and a negative electrode wire of an electric device can be completed at the same time. Of course, in order to better adapt to various devices, a plurality of first electrode metal connecting areas 13 and second electrode metal connecting areas 14 may be provided, and preferably, one first electrode metal connecting area 13 and two second electrode metal connecting areas 14 are provided, wherein one first electrode metal connecting area 13 and one second electrode metal connecting area 14 are provided at adjacent positions on the same side, so that welding can be facilitated; the other second electrode metal connection region 14 is disposed at the other side opposite to the first electrode metal connection region 13, which facilitates the interference contact, so that the force applied during the interference contact is uniform.
The method can be understood as setting one positive metal connection area and two negative metal connection areas, or two positive metal connection areas and one negative metal connection area, wherein one positive metal connection area and one negative metal connection area are set at adjacent positions on the same side, and the other positive metal connection area or negative metal connection area is set at an opposite position on the other side, and in a specific use process, if an external electric device adopts a welding mode, the positive metal connection area and the negative metal connection area adjacent on the same side can be preferably selected for use, so that the welding can be facilitated; if the mode of conflict electric conduction is carried out, the positive pole metal connecting area and the negative pole metal connecting area which are opposite to each other at two sides can be selected and used preferably, so that the uniformity of conflict electric conduction stress can be facilitated, and the stability is further improved.
The metal supporting plate 22 is used to fixedly connect the metal bottom case main body 20 and the insulating body 10, and the metal supporting plate 22 and the metal bottom case main body 20 can be integrally injection-molded to improve the structural strength and reduce the processing difficulty. It should be understood that the metal supporting plate 22 not only serves to support the fixed connection, but also serves to transmit electric conduction from the second metal elastic structure 24 on the metal bottom case body 20 to the metal connection structure by making interference contact with the bottom of the button cell 40. The two metal support plates 22 are opposite to each other, and can limit the button cell 40 in the installation space 30 from two opposite directions. The end of the metal supporting plate 22 is away from the end of the metal bottom case main body 20, and after the end of the metal supporting plate 22 is fastened to the external connection surface 12 of the insulating body 10, the metal bottom case main body 20 can be electrically connected to the external connection surface 12.
According to the button cell lead seat, an installation space 30 is formed among the metal bottom shell main body 20, the metal support plate and the insulating body 10 so as to be used for installing the button cell 40, after the button cell 40 is installed in the installation space 30, one electrode of the button cell 40 can be electrically conducted with the first metal elastic structure 50, and therefore the first electrode metal connection area 13 of the external connection surface 12 can be conducted with one electrode of the button cell 40; the other electrode is electrically connected with the second metal elastic structure 24, so that the second electrode metal connection region 14 of the external connection surface 12 can be electrically connected with the other electrode of the button cell 40; the first electrode metal connecting area 13 and the second electrode metal connecting area 14 are used for welding or abutting against and electrically conducting positive and negative electrode wires of the electric equipment, and electrode wires of the electric equipment can be conducted with the electrodes of the button cell 40 after being welded or abutting against and contacted with the first electrode metal connecting area 13 and the second electrode metal connecting area 14, so that the electric equipment is electrically conducted with the button cell 40; because the electrode wire of the electric equipment is welded on the insulating body 10, the difficulty of welding fixation or contact conflict is smaller, so that the welding efficiency is higher, and the installation and connection efficiency of the button cell 40 and the electric equipment can be improved.
In addition, since the electrode wires of the electric equipment are not directly welded to the button cell 40, the button cell 40 can be prevented from being damaged by the welding process. If the electric energy of the button cell 40 is exhausted or fails, the button cell 40 can be disassembled and assembled from the button cell wire seat to realize replacement, so that the replacement difficulty of the button cell 40 is reduced, and the replacement efficiency of the button cell 40 is improved.
Further, the external connection assembly is fixedly connected with the bottom shell assembly, the button cell 40 is accommodated in the installation space 30, the shell of the button cell 40 is extruded, the service life of the button cell 40 can be prolonged, gas can be generated when an electric core of the button cell 40 works, the shell of the button cell 40 can be extruded when the gas is too much, and if the shell is extruded all the time, the positive and negative shells of the button cell 40 can be loosened and then contacted with air, so that the service life of the button cell 40 is shortened; the button cell 40 can also be avoided bringing danger in breaking down, for example the short circuit, and inside quick production is gaseous, breaks away button cell 40 casing, causes the explosion, owing to have stopping of external subassembly and drain pan subassembly, leads to button cell 40's shell to be difficult to break away, forms the space and inspects gas, and then can't cause the explosion to cause the damage.
The first metal elastic structure 50 may be a conductive elastic sheet additionally connected to the insulating body 10, and the specific form of the first metal elastic structure 50 is not limited, and only needs to have elasticity and tilt to the installation space 30. The first metal elastic structure 50 can ensure the abutting with the button cell 40, thereby improving the electrical conduction stability of the insulating body 10 and the button cell 40.
The second metal elastic structure 24 can be integrally formed on the metal bottom case body 20, so as to reduce the cost of the second metal elastic structure 24. The second metal elastic structure 24 can ensure the abutting with the button cell 40, thereby improving the stability of the electrical conduction between the metal bottom case main body 20 and the button cell 40, or stably clamping the electrode wire to the button cell 40. Because two end faces of the button cell 40 are respectively contacted with the first metal elastic structure 50 and the second metal elastic structure 24 in an abutting mode, the shock absorption effect can be achieved, and the damage of the cell caused by the vibration of electronic equipment in fading can be avoided.
