Description

Title of the invention: Stamped and folded part for a button-type battery holder, button-type battery holder and corresponding device

[0001] The invention relates to a stamped and folded part for a button-type battery holder for vertically holding a button-type battery on a printed circuit board, to a button-type battery holder, which comprises two stamped and folded parts, and to a device, which has at least one stamped and folded part.

[0002] On electronic vehicle mounting devices, such as digital tachographs, vehicle data recorders or on-board toll units, it is necessary to provide battery element retention devices which ensure that the batteries remain in the intended final mounting position, also during vibrations and shocks, in order to guarantee a reliable power supply to the vehicle mounting device.

[0003] In the current state of the art, these battery cell retaining devices are often made of composite construction and comprise a plastic element and a metal element. Designs such as metal brackets are also common. A composite construction is more expensive to manufacture than a battery cell retaining device made of metal. Battery cell retaining devices often require two different metal parts, necessitating additional production lines.

[0004] Button cell battery holders for retaining button cell batteries are often arranged for horizontal storage of button cell batteries. Horizontal storage means that a main surface of the button cell battery is oriented parallel to a main surface of a printed circuit board to which the button cell battery holder is attached. In this way, the button cell battery holders use a relatively large area on the printed circuit board, which is therefore not available for other components on the printed circuit board.

[0005] The following button-type battery holders are known from the prior art:

[0006] TW M567488 U describes a battery connector with a battery holder and conductor connections formed in one piece, which is installed on an electronic device.

[0007] US 8091224 B2 describes a method for coupling a battery in an embedded system. The method comprises making a hole, which extends through a printed circuit board (PCB), insertion of part of the battery into the hole and electrical coupling of the battery with at least one contact.

[0008] CN 205429029 U describes a button-type battery holder.

[0009] CN 211858791 U describes a button cell holder with a base, two plates supports, a limiting piece, a side wall and a clamping hook.

[0010] CN 211858790 U describes a button cell socket comprising a housing, which itself consists of a base and a rotatably mounted lid, a rod connecting the base and the lid, and a torsion spring pressed onto the rod. An electrode arrangement is mounted in the housing and consists of a first and a second electrode plate, which are spaced apart. The first electrode plate is fixed to the side wall on one side of the base, while the second electrode plate is fixed to the side wall on the other side of the base. A button cell battery is held between the first and second electrode plates.

[0011] An objective of the present invention is to disclose a button-type battery holder for the vertical storage of a button-type battery requiring less manufacturing effort than conventional button-type battery holders.

[0012] To this end, the invention relates to a stamped and folded part for a button-type battery holder for the vertical holding of a button-type battery on a printed circuit board, characterized in that the stamped and folded part has a main surface element, which includes a first contact surface and a second contact surface opposite the first contact surface; a lateral surface element is disposed on a lateral edge of the main surface element, which lateral surface element protrudes perpendicularly from the first contact surface; the lateral surface element has a lateral tab, which protrudes from a lateral contact surface of the lateral surface element, which is arranged to exert a force against an envelope surface of the button-type battery;The stamped and folded part has on the lower edges of the main surface element and the lateral surface element a fastening device for attaching the stamped and folded part to the printed circuit board; the main surface element has a support tab, which protrudes perpendicularly from the first contact surface of the main surface element, through which a support surface oriented perpendicularly to the main surface element is provided for supporting the button cell; the main surface element has two main tabs, each of the main tabs having a first main tab section which protrudes from the first contact surface and is arranged to exert a force on the button cell and a second main tab section; which protrudes from the second contact surface and is arranged to exert a force on the button-type battery.

[0013] A first aspect of the invention relates to a stamped and folded part for a button cell battery holder for vertically holding a button cell battery on a printed circuit board. In other words, the stamped and folded part is intended for use in the button cell battery holder so that the holder can vertically hold the button cell battery on the printed circuit board. Vertical holding means holding the button cell battery perpendicular to the printed circuit board to which the button cell battery holder is attached.

[0014] The stamped and bent part is intended to have a main surface element, which comprises a first contact surface and a second contact surface opposite the first contact surface. In other words, the stamped and bent part comprises the main surface element, which has the first contact surface on one side of the main surface element and the second contact surface, which is located on one side of the main surface element opposite the first contact surface.

[0015] The stamped and bent part is intended to have a lateral surface element on a lateral edge of the main surface element. The lateral surface element extends perpendicularly beyond the first contact surface. In other words, the lateral surface element is located on the lateral edge of the main surface element. The lateral surface element extends beyond the main surface element in the direction of the first contact surface. Therefore, the stamped and bent part comprises the main surface element and the lateral surface element, which together form an L-shaped profile.

[0016] The lateral surface element is provided to have a lateral tab. The lateral tab extends from a lateral contact surface of the lateral surface element. The lateral surface element is arranged to exert a force against an envelope surface of the button-type stack. In other words, it is provided that, in the case where the button-type stack is arranged on the stamped and folded part such that a front surface of the button-type stack is in contact with the first contact surface of the main surface element and an envelope surface of the button-type stack is in contact with a lateral contact surface of the lateral surface element, a force is exerted by the lateral tab against the envelope surface of the button-type stack.In particular, the side tab can be positioned above a center of the button-type stack so that the force exerted on the shell surface of the button-type stack has a component acting in the direction of a lower edge of the stamped and folded part. The tab. The lateral can thus act as a retaining element to prevent the button-type battery from detaching from a specified receiving position in the button-type battery holder.

[0017] The stamped and folded part has a fastening device on the lower edges of the main surface element and the lateral surface element. The fastening device is arranged to fix the stamped and folded part to the printed circuit board.

[0018] The main surface element has a support tab, which protrudes perpendicularly from the first contact surface of the main surface element. A support surface oriented perpendicularly to the main surface element is provided by the support tab for the button cell battery. In particular, the support surface is oriented horizontally in a mounting position and therefore parallel to a main surface of the printed circuit board. In other words, the button cell battery is intended to rest on the support surface of the support flange in an arrangement in the specified receiving position. This prevents the button cell battery from sliding towards the bottom edge.

[0019] The main surface element has two main tabs. Each main tab has a first main tab section, which extends from the first contact surface and is arranged to exert a force on the button cell. In other words, each main tab is arranged to exert a force on the button cell when the latter is in contact with the first contact surface in the specified receiving position, on the respective first main tab section. Each main tab further has a second main tab section, which extends from the second contact surface. In other words, the second contact surface extends in a direction oriented opposite to the first contact surface. The main tab is arranged to exert a force on the button cell when the latter is in contact with the second contact surface, by means of the second contact surface.

[0020] The invention has the advantage that the stamped and bent part is suitable for providing a button-type battery holder consisting of two identical stamped and bent parts. In this way, it is possible to save on production costs and effort. It is possible to provide a button-type battery holder in which the button-type battery is arranged between two identically oriented stamped and bent parts.

[0021] A further embodiment of the invention provides that, in the second main leg section, the respective main leg has a main leg surface, which is arranged parallel to the second contact surface and is offset perpendicularly with respect to the second contact surface. In other In terms of these, each of the main legs has a main leg surface, which is oriented planar-parallel to the second contact surface. Relative to the second contact surface, the respective main leg is offset by a certain distance from the second contact surface. Each of the main legs also has a respective main leg edge in the first main leg section. The respective main leg edge is oriented parallel to the first contact surface and offset by a certain distance from the first contact surface. In other words, the respective main leg edge is offset from the first contact surface. It is therefore possible for the button cell battery to be placed on the second contact surface or to be in contact with the main leg edge.

[0022] A further embodiment of the invention provides that the side leg has a side leg support section, which extends obliquely from the lateral contact surface. In other words, the side leg has the side leg support section, which is connected at one end to the lateral contact surface and is connected at the other end to the lateral contact surface and holds it in place. The side leg support section extends from the lateral contact surface. The lateral leg surface is held in place by the side leg support section, the lateral leg surface being oriented parallel to and offset from the lateral contact surface of the lateral surface element.The additional feature resulting from this design is that, when inserting a button-type battery, the side tab is stretched in such a way that the side tab surface presses against the casing surface and thus prevents the button-type battery from slipping out of the battery holder.

[0023] A further embodiment of the invention provides that the main surface element has a central tab, which protrudes from the first contact surface of the main surface element. The central tab is arranged to exert a force against the button cell battery.

[0024] A further embodiment of the invention provides that the main surface element has a central tab surface, which is oriented planarly with respect to the first contact surface and is arranged offset with respect to the first contact surface, which is arranged to exert a force against the button-type battery, with the central tab surface.

[0025] A further embodiment of the invention provides that the central tab has a central guide surface, which extends from the upper edge of the central guide surface in the direction of the first contact surface. The central guide surface is arranged to guide the button cell battery during insertion of the button cell battery along the central guide surface and to The central tab is stretched. In other words, the central guide surface is designed to guide the button cell when the button cell is inserted into the battery holder so that it is guided along the central tab surface and the central tab is stretched.

[0026] A further embodiment of the invention provides that the fastening device includes pin elements for a pin-and-paste arrangement. In other words, the pin elements are arranged on the lower edges of the stamped and bent part, which elements are shaped to be guided into a corresponding opening in a printed circuit board in order to fix the stamped and bent part to the printed circuit board by means of a pin-and-paste arrangement.

[0027] A further embodiment of the invention provides that the fastening device comprises surface-mounted (SMD) tab elements for an SMD-type arrangement. In other words, the SMD tab elements are arranged on the lower edges of the stamped and bent part, which elements are arranged to fix the stamped and bent part to the printed circuit board in a surface-mounted device arrangement.

[0028] A further embodiment of the invention provides that the main surface element has a recess extending from the lower edge of the main surface element in the direction of an upper edge of the main surface element or towards an upper edge of the main surface element. In other words, the recess is located in a lower area of ​​the main surface element. This provides the advantage of an area in which components can be arranged on the printed circuit board.

[0029] A second aspect of the invention relates to a button cell battery holder, which has two stamped and folded parts in accordance with the first aspect of the invention and as defined above. The button cell battery holder is designed to store a button cell battery perpendicular to a printed circuit board. The button cell battery holder is formed by two stamped and folded parts, which can be attached to the printed circuit board by means of their fastening devices. The two stamped and folded parts of the button cell battery holder can have the same orientation and be offset from each other. A receiving area for the button cell battery is at least partially defined by the two stamped and folded parts. The receiving position of the button cell battery is specified by the receiving area.The receiving area is at least partially limited by a first contact surface of a first piece among the stamped and folded pieces and by a second surface. The contact area of ​​a second stamped and bent part is defined by a lateral contact surface of the first stamped and bent part. The button-type stack holder is arranged so that, in the receiving position, the button-type stack rests on the bearing surface of the support flange of the first stamped and bent part. The relationship between the position of the support flange and the arrangement of the lateral tab is chosen such that the button-type stack is pressed against the bearing surface of the support flange by the lateral flange.The button cell holder is arranged so that, when the button cell is placed in the receiving position, the leading edge of the first stamped and bent part is in contact with one of the button cell's pole faces, and the leading edge of the second stamped and bent part is in contact with the second pole face of the button cell. In this way, the first stamped and bent part provides contact with the first pole of the button cell, and the second stamped and bent part provides contact with the second pole. Advantageously, the button cell holder has two identical stamped and bent parts, so it is not necessary to manufacture separate stamped and bent parts.

[0030] A third aspect relates to a device comprising a printed circuit board and at least one stamped and folded part in accordance with the first aspect of the invention and as defined above. In particular, the device may be a digital tachograph, a vehicle data recorder, or an on-board toll collection unit. It may be provided that at least one button cell battery is held on the printed circuit board by means of at least one stamped and folded part. It may be provided that the button cell battery is held by the stamped and folded part and by another element, such as a wall of the device, for example, or by two stamped and folded parts, which may be provided as a button cell battery holder in accordance with the second aspect of the invention.

[0031] According to one embodiment, the device defined above is characterized in that a receiving space for receiving a button-type battery is formed by at least one stamped and folded part and at least one wall of a housing of the device.

[0032] A further embodiment of the invention provides that the device has at least two of the stamped and folded parts, which are arranged on the printed circuit board of the device as a button-type battery holder in accordance with the second aspect of the invention and as defined above.

[0033] A further embodiment of the invention provides that at least one stamped and folded part is arranged on the printed circuit board such that the button cell battery is held by the stamped and folded part and by at least one wall of a housing. In other words, a receiving area for the reception of the button-type battery is at least partially limited by the stamped and folded part and by the casing.
