Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a hybrid electrically self-locking wire-to-board circular connector. Background Technology

[0002] A button cell, also known as a coin cell, is a battery that is shaped like a small button. Due to its small size, button cells are widely used in various microelectronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, remote controls, electric toys, pacemakers, electronic hearing aids, counters, and cameras.

[0003] Button battery connectors are used to hold button batteries and are generally soldered onto PCB boards for powering module clocks. The existing button battery connectors have the following shortcomings: (1) Insufficient waterproof performance. Existing products generally rely on static waterproof rings for sealing, which cannot meet the waterproof requirements of dynamic rotation scenarios, and the gaps in the battery compartment are not treated with secondary waterproofing; (2) When rotating the battery cover, conventional connectors have the following problems: the positive terminal is directly exposed in the rotation path and is easily scratched and deformed by the battery cover. Repeated disassembly and assembly operations will cause fatigue fracture of the terminal elastic arm; (3) Low modularity. In common industry designs, electronic components (such as PCBs) and connectors are designed separately, which increases the assembly process. Utility Model Content

[0037] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0038] Example:

[0039] This embodiment describes the structure of a button battery connector.

[0040] like Figure 1 , 2 As shown, Figure 1 This is a schematic diagram of the structure of a button battery connector according to this utility model. Figure 2 This is an exploded view of a button cell battery connector structure. A button cell battery connector includes a battery holder 1 for mounting a button cell battery 3.

[0041] The battery holder 1 includes an electronic component 17 mounted on a plastic body 11. The plastic body 11 has a receiving groove 2 for mounting a button battery 3. The button battery 3 is inserted into the receiving groove 2 and is in contact with the negative terminal 14 and the positive terminal 15 located at the bottom of the receiving groove 2.

[0042] The upper end of the receiving slot 2 is provided with a rotatable battery cover 13 for placing the button battery 3 behind the receiving slot 2 and pressing it tightly on top of the button battery 3;

[0043] A rear cover 12 is also provided at the bottom of the receiving groove 2, and the connection seam between the rear cover 12 and the bottom of the receiving groove 2 is filled and sealed with waterproof adhesive 4.

[0044] In this embodiment, the button battery connector and electronic components are combined into one part, and the outside is waterproofed (the connection between the back cover and the bottom of the receiving groove is sealed with waterproof glue), which reduces the assembly process of the connector and also has waterproof performance.

[0045] To improve the stability of the button battery after it is installed in the battery holder and to enhance the ease of operation of the battery cover, in a preferred embodiment, the battery cover and the receiving slot are designed as a rotatable screw-lock structure. Specifically, as shown... Figure 3 , 4 As shown, Figure 3 This is a schematic diagram of the receiving groove in the preferred embodiment. Figure 4 This is a schematic diagram of the rotatable battery cover structure in a preferred embodiment. The rotatable battery cover 13 is provided with a locking part, which includes at least two locking bevels 132 provided on the rotatable battery cover 13 and a locking spring arm 131 extending circumferentially along the rotatable battery cover 13 and connected to the locking bevels 132;

[0046] The locking bevel 131 and the corresponding mounting bevel 21 on the receiving groove 2 form a clockwise locking and counterclockwise unlocking movement path. The locking spring arm 131 and the corresponding mounting buckle 22 on the receiving groove 2 form a locking point. The rotatable battery cover 13 is installed by a spiral lock between the locking part and the receiving groove.

[0047] Working principle: As the rotatable battery cover is rotated clockwise, the latching bevel on the rotatable battery cover slides into the mounting bevel on the receiving groove. Subsequently, the latching spring arm slides to the mounting point below the receiving groove and forms a latching structure with the mounting point to lock the battery. At this time, the rotatable battery cover is installed in the receiving groove and is located on the button battery.

[0048] When rotated counterclockwise, the latching ramp gradually slides out along the mounting ramp. As the rotatable battery cover continues to rotate counterclockwise, the latching spring arm separates from the mounting point, thus unlocking the battery. At this point, the rotatable battery should leave the receiving slot.

[0049] The spiral locking mechanism described above improves the ease of installation between the battery cover and the receiving slot, protects the button battery, and enhances the stability of the rotatable battery cover's engagement with the plastic body. The button battery cover's mounting interface requires no orientation adjustment; simply twist it clockwise until you feel a slight resistance, ensuring proper assembly and preventing accidental damage to the connector.

[0050] To further improve the waterproofness of the button battery connector, in addition to sealing the connection seam with waterproof adhesive at the bottom of the button battery receiving slot, in a preferred embodiment, an annular sealing groove 133 for placing the waterproof ring 16 is also provided on the rotatable battery cover 13. When rotated clockwise, the waterproof ring slides into the latch as the battery cover rotates, sealing the connection between the receiving groove and the rotatable battery cover.

[0051] The waterproof ring design in this invention satisfies the waterproofing requirements between the receiving groove where the button battery is located and the mounting seam of the rotatable battery cover in dynamic rotation scenarios, greatly improving the waterproofing performance. Tests have shown that it can achieve the waterproofing standard of 1 atmosphere.

[0052] In a preferred embodiment, to facilitate operation of the rotatable battery cover, a rotating part 19 is radially provided along the outer side wall of the rotatable battery cover 13, and an auxiliary groove 134 for assisting disassembly is formed on the upper surface of the rotatable battery cover 13. Correspondingly, a rotatable travel area 18 is provided in the area of ​​the plastic body 11 corresponding to the rotating part 19. During rotation, the rotating part moves along the rotatable travel area.

[0053] like Figure 5 , 6 As shown in Figure 7, Figure 5 This is a schematic diagram of the negative terminal substructure described in the preferred embodiment. Figure 6 This is a schematic diagram of the positive terminal substructure described in the preferred embodiment. Figure 7 This is a schematic diagram of the bottom structure of the plastic body in the preferred embodiment. The negative terminal 14 includes a first elastic arm 141 that contacts the negative terminal of the button battery 3;

[0054] Fixing part 142 and fixing part 143 are used to fix the negative terminal 14 to the receiving groove 2. The fixing part 142 and fixing part 143 are inserted into the bottom connecting hole 23 of the receiving groove 2.

[0055] And a welding part 144 for welding the negative terminal 14 to the electronic component 17, the welding part 144 being inserted through a connection hole on the plastic body 11 and welded to the electronic component 17.

[0056] The positive terminal 15 includes a second elastic arm 151 that contacts the positive terminal of the button battery 3;

[0057] Fixing parts 4 152 and 5 153 are used to fix the positive terminal 15 to the receiving groove 2. The fixing parts 4 152 and 5 153 are inserted into the bottom connecting hole 1 23 of the receiving groove 2.

[0058] And a second welding part 154 for welding the positive terminal 15 to the electronic component 17, the second welding part 154 being inserted through a connection hole on the plastic body 11 and welded to the electronic component 17.

[0059] Preferably, the second elastic arm 151 is in the form of two arms opening and embracing, and is installed into the receiving groove 2 through the fixing part four 152 and the fixing part five 153.

[0060] For button battery connectors, in addition to improving waterproof performance, another issue that needs to be addressed in the technological development of this field is that when the battery cover is rotated during operation, the positive terminal exposed under the battery cover is easily scratched or damaged by the battery.

[0061] In the preferred embodiment, the spiral locking structure provides some protection for the positive terminal. However, to ensure that the positive terminal exposed in the receiving slot is not affected by the rotation of the rotatable battery cover, a protective part 25 is provided on the inner diameter sidewall of the receiving slot 2, located above the positive terminal 15. When the positive terminal is installed into the plastic body and extends into the receiving slot to facilitate contact after the button battery is installed, the second elastic arm opens, and its upper end is protected below the protective part. When the rotatable battery cover rotates into the receiving slot, it will not rub against the positive terminal, thus preventing damage to the positive terminal.

[0062] Installation: Press the negative and positive terminals into the plastic body and install them according to the corresponding connection holes and connecting holes; install the back cover to the seam of the receiving groove and apply waterproof glue before assembling; solder the electronic components to the positive and negative terminals; pre-install the waterproof ring into the annular sealing groove of the battery cover.

[0063] This invention relates to a button battery connector that is ingeniously designed and highly practical. The rotatable battery cover, in conjunction with the receiving slot, improves the ease of battery cover installation. Furthermore, by incorporating a protective section inside the receiving slot, the positive terminal is protected, preventing wear on the positive terminal when the battery cover rotates into the receiving slot.

[0064] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
