Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a battery holder connector that is prevented from being mistakenly disassembled. Background Art

[0002] Button batteries, also known as button batteries, are batteries with an appearance similar to that of a small button. Due to their small size, button batteries are widely used in various microelectronic products. The battery holder connector used to load button batteries is generally soldered on the PCB board to power microelectronic products.

[0003] Existing battery holder connectors for loading button batteries usually adopt an open structure, and use the buckle on the outer edge of the battery holder connector to limit the button battery to prevent the battery from falling off, which makes it easier to take the battery. However, this fixing form will inevitably cause the battery to pop out during exercise, causing contact problems. Moreover, this type of battery holder connector is widely used in electronic products such as children's watches, mobile phones, and tablets, and the overlap with the child population is high. This leads to the safety hazard of easily removable button batteries being swallowed by children, and the safety performance cannot be guaranteed.

DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] Example

[0028] See also Figures 1 to 6A battery holder connector that prevents accidental disassembly comprises a shell 1 and a positive terminal 5 and a negative terminal 4 installed in the shell 1. The shell is provided with a receiving groove for placing a button battery 6. When the button battery is placed in the receiving groove, the positive terminal and the negative terminal are respectively pressed and contacted with the button battery; the receiving groove is covered with a cover plate 2, one end of the cover plate is hinged to the shell, and the other end is detachably connected and fixed to the shell.

[0029] The housing 1 is fixedly connected with a hinge part 11 and a fixed part 12 on both sides, one end of the cover is connected with a hinge shaft 21 installed in the hinge part, and the other end of the cover is connected and fixed with the fixed part through a fastening mechanism 3.

[0030] A nut groove is provided in the fixing part, and a fixing hole 22 adapted to the nut groove is provided at one end of the cover plate connected to the fixing part. The fastening mechanism 3 includes a nut installed and fixed in the nut groove and a bolt passing through the fixing hole 22 and cooperating with the nut. The end of the cover plate is detachably fixed to the fixing part by the cooperation of the bolt and the nut.

[0031] A negative terminal slot 13 and a positive terminal slot 14 are provided in the accommodating groove of the shell 1, and the negative terminal slot and the positive terminal slot are both provided with through holes penetrating the shell, the negative terminal 4 and the positive terminal 5 both have terminal welding feet, the negative terminal and the positive terminal are respectively inserted and installed in the negative terminal slot and the positive terminal slot, and the terminal welding feet of the negative terminal and the positive terminal extend out of the shell through the corresponding through holes respectively.

[0032] The positive terminal 5 and the negative terminal 4 are both elastic. When the button battery is installed, the positive terminal is located on the side of the button battery, and the negative terminal is located below the button battery. The positive terminal body is U-shaped and can be compressed and deformed along the radial direction of the shell. The negative terminal includes an elastic part 41, and the negative terminal can be compressed and deformed along the axis of the shell through the elastic part.

[0033] The positive terminal 5 is provided with a buckle 51 pointing to one side of the button battery along the radial direction of the shell, and the length of the buckle does not exceed the maximum displacement of the positive terminal under compression deformation. An inverted buckle 15 is provided inside the side of the upper end of the shell away from the positive terminal, and the button battery is limited by the buckle and the inverted buckle to prevent it from falling off.

[0034] The elastic portion 41 is specifically at least one elastic arm extending from one end of the negative terminal to the other end and having an angle with the negative terminal body.

[0035] The bottom side of the cover plate 2 is provided with a limiting portion 23 extending downward to enhance the limiting capability of the button battery.

[0036] In the anti-mistaken-disassembly battery holder connector of this embodiment, when inserting a button battery, after opening the cover plate 2 through the hinge shaft 21, first press the positive terminal to shrink the buckle 51 to facilitate battery installation. After the battery is inserted, release the positive terminal and the buckle moves back to limit the button battery with the inverted buckle 15 on the shell to prevent the battery from leaving the accommodating slot. At this time, the elastic part 41 of the negative terminal 4 is compressed and deformed. Similarly, when the button battery needs to be removed, it is only necessary to press the positive terminal to shrink the buckle, and the elastic part 41 rebounds, so that the button battery can be tilted up for easy removal.

[0037] However, when children come into contact with the above connector, they may easily press the positive terminal accidentally, causing the battery to pop out and be swallowed by the children. Therefore, the battery holder connector of this embodiment can use a hinged shaft to cover the cover plate. At this time, the fixing block 22 corresponds to the position of the nut slot on the fixing part 12, and the bolt is used to cooperate with the nut fixed in the nut slot to tighten it, so as to prevent accidental disassembly. Here, in order to improve flexibility, the nut slot can be opened from the side of the fixing part 12, and the nut is placed in the nut slot from the side. At the same time, a through hole that passes through the nut slot is opened at the upper end of the fixing part, and the position of the through hole is adapted to the fixing hole 22. When installing, the bolt passes through the fixing hole and the through hole from the top in turn and is tightened with the nut. In this scheme, the bolts and nuts are easy to replace, and the slipping of the teeth caused by long-term use or assembly and disassembly errors is prevented.

[0038] The beneficial effects of the utility model are as follows: through the elastic positive terminal and negative terminal, the buckles on the terminals, the elastic part and the undercut on the shell, the installation firmness of the button battery can be enhanced, and the contact stability between the positive and negative terminals and the battery can be enhanced. The cover plate is fixed in a hinged manner with a fastening mechanism, and it is difficult to remove the battery without tools. This can effectively prevent children from accidentally removing the button battery during use, which may lead to accidental ingestion, thereby increasing the safety of use.

[0039] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify and vary the above embodiments within the scope of the present invention.
