Description

Technical Field

[0001] The utility model relates to the technical field of button batteries, in particular to a button battery holder. Background Art

[0002] Button batteries are also called button batteries. Button battery holders are button battery connectors, which are used to load button batteries. They are usually welded on PCB boards and used to power module clocks. Button batteries are widely used in cameras, collections, computers and other electronic products. In order to facilitate battery replacement, the design of battery holders is currently developing in the direction of stable connection and safe use.

[0003] For example, the Chinese patent of the prior art CN215220852U discloses a button battery holder, including a battery base, and a positive spring piece and a negative spring piece installed on the battery base; the negative spring piece includes a body, and a negative terminal connected to the body, a buckle groove is provided at the connection between the body and the negative terminal, and the battery base is provided with an insertion port for the negative terminal to pass through; the battery base has a buckle point, and the buckle point extends toward the insertion port to buckle with the buckle groove of the negative spring piece.

[0004] However, in today's fiercely competitive electronics industry, thin and delicate products are a great way to attract consumers' attention. However, the button battery holder in the above prior art occupies more space on the circuit board due to the thick plastic and other reasons, and looks thick, so it cannot meet the current market demand. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a button-type battery holder with a simple structure and layout, which is light, thin and beautiful.

[0006] To achieve the above purpose, the utility model adopts the following contents:

[0007] The utility model provides a button battery holder, which includes a holder, wherein the middle part of the holder is inwardly recessed to form a semi-circular recessed groove for placing the button battery, and the front and rear openings of the semi-circular recessed groove are respectively provided with a positive conductive sheet and a negative conductive sheet, and the positive conductive sheet and the negative conductive sheet are both connected to the holder in a snap-fitting manner, and a spacing is left between the positive conductive sheet and the negative conductive sheet;

[0008] An elastic positive contact portion facing inward is formed in the middle of the positive conductive sheet, and the upper portions of both sides of the positive conductive sheet extend outward to form positive wiring pins. An elastic negative contact portion facing inward is formed in the middle of the negative conductive sheet, and the lower portion of the negative conductive sheet extends outward to form negative wiring pins.

[0009] According to a button battery holder provided by the utility model, a rectangular opening is formed in the middle of the positive electrode conductive sheet, and two elastic positive electrode contact parts are formed in the rectangular opening, which are symmetrically spaced and extend obliquely inward. A protruding smooth contact protrusion is formed at the lower part of the elastic positive electrode contact part, and the smooth contact protrusion protrudes from the plane where the positive electrode conductive sheet is located. The positive electrode of the button battery is usually a flat and smooth surface. In order to avoid scratching its surface, a smooth contact protrusion is designed so that the two form a surface-to-surface contact. In this way, the smooth contact protrusion can well abut against the positive electrode of the button battery to ensure good electrical contact, and to a certain extent, it can also form an elastic clamping effect on the button battery, which is conducive to improving the fixing effect of the button battery.

[0010] According to a button battery holder provided by the utility model, two triangular openings are symmetrically formed in the middle of the negative electrode conductive sheet, and a triangular elastic negative electrode contact portion is formed by extending obliquely inward in the triangular opening. The negative electrode of the button battery is usually a non-smooth surface with small convex points. In order to avoid poor contact, a triangular elastic negative electrode contact portion is designed so that the two form a point-surface contact. In this way, the elastic negative electrode contact portion can well abut against the negative electrode of the button battery to ensure good electrical contact, and to a certain extent, it can also form an elastic clamping and limiting effect on the button battery, and cooperate with the smooth contact protrusion to achieve a fixing effect on the button battery.

[0011] According to the button-type battery holder provided by the utility model, the top of the positive electrode conductive sheet extends vertically upward to form a fitting rib portion, thereby increasing the insertion depth of the semi-annular recess groove to a certain extent.

[0012] According to the button battery holder provided by the utility model, the top of the negative electrode conductive sheet extends outward obliquely to form an extended edge, so as to facilitate the button battery to be quickly inserted into the semi-annular recessed groove from the top between the positive electrode conductive sheet and the negative electrode conductive sheet.

[0013] According to a button battery holder provided by the utility model, two symmetrical first slots and two symmetrical second slots are arranged on the outer side of the holder, and hook parts are protruding from the first slots and the second slots, and the two sides of the positive conductive sheet are bent to form a first plug end that can be inserted into the first slot, and the two sides of the negative conductive sheet are bent to form a second plug end that can be inserted into the second slot, and the first plug end and the second plug end are both provided with a slot that can form a snap fit with the hook part. The snap fit between the slot and the hook part facilitates the assembly of the positive conductive sheet and the negative conductive sheet, and they will not be easily separated when subjected to a certain external force.

[0014] According to the button battery holder provided by the utility model, the holder body is a plastic part. The use of plastic parts not only has low manufacturing cost, but also has light volume and higher toughness than metal.

[0015] Compared with the prior art, the utility model has the following technical effects: the utility model has a simple structure and a reasonable design. By providing the seat body, the positive electrode conductive sheet and the negative electrode conductive sheet, the positive electrode conductive sheet and the negative electrode conductive sheet can respectively abut against the positive electrode and the negative electrode of the button battery, effectively reducing the installation thickness of the battery seat and achieving a light and thin effect; by providing the elastic positive electrode contact part and the elastic negative electrode contact part, not only can good electrical contact be formed between the positive electrode and the negative electrode of the button battery, but also an elastic clamping effect is formed on the button battery, which is conducive to improving the fixing effect of the button battery and ensuring that the button battery can be stably placed in the semi-annular recessed groove.

[0025] An elastic positive contact portion 210 facing inward is formed in the middle of the positive conductive sheet 20, and the upper parts of both sides of the positive conductive sheet 20 extend outward to form positive terminal pins 220.

By providing an elastic positive contact portion and an elastic negative contact portion, not only can good electrical contact be formed between the positive and negative electrodes of the button battery, but also an elastic clamping effect is formed on the button battery, which is beneficial to improving the fixing effect of the button battery and ensuring that the button battery can be stably placed in the semi-annular recessed groove.

[0027] In this embodiment, a rectangular opening 201 is formed in the middle of the positive electrode conductive sheet 20, and two elastic positive electrode contact parts 210 are formed in the rectangular opening 201, which are symmetrically spaced and obliquely extended inward. A protruding smooth contact protrusion 211 is formed at the lower part of the elastic positive electrode contact part 210, and the smooth contact protrusion 211 protrudes from the plane where the positive electrode conductive sheet 20 is located. The positive electrode of the button battery is usually a flat and smooth surface.
