Technical Field

[0001] This utility model relates to the field of electronic lock technology, specifically to a motor power supply circuit connection structure for electronic locks. Background Technology

[0002] Currently, most existing electronic lock circuit connections use wiring and welding structures, which increases the risk of poor soldering caused by traditional wire harness connections, or wire harness tangling and falling off during production and transportation. This increases labor costs and component wear due to the need for prevention during welding and production operations. Therefore, how to reduce the poor soldering or wire harness tangling caused by wiring and welding structures is a structural improvement that needs to be made. Utility Model Content

The power supply circuit connection structure includes a power PCB board, insert springs, a battery negative terminal connector, a battery positive terminal connector, and several battery spring plates. The power PCB board is nested within the housing. Two terminals of the motor are nested and pressed against one end of the insert spring, and the other end of the insert spring is pressed against the output terminal of the power PCB board. One end of the battery negative terminal connector and one end of the battery positive terminal connector are snapped into the bottom input terminal of the power PCB board. The battery pack is connected in series via several battery spring plates, and the positive and negative ends of the battery pack are pressed against the other ends of the battery negative terminal connector and the battery positive terminal connector, respectively.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 This utility model provides a technical solution:

[0016] like Figure 1As shown, a motor power supply circuit connection structure for an electronic lock is disclosed. A battery pack 2, a motor 3, a drive device 4, and a latch 5 are nested within the lock housing 1. The battery pack 2 is connected to the motor 3 via a power supply circuit connection structure 6. The motor 3 drives the latch 5 to open and close via the drive device 4. The power supply circuit connection structure 6 includes a power PCB board 61, a plug spring 62, a battery negative terminal connector 63, a battery positive terminal connector 64, and two battery spring plates 65. The power PCB board 61 is nested within the housing 1. The two terminals of the motor 3 are nested and pressed against one end of the plug spring 62, and the other end of the plug spring 62 is pressed against the output terminal of the power PCB board 61. One end of the battery negative terminal connector 63 and the battery positive terminal connector 64 are snapped into the bottom input terminal of the power PCB board 61. The battery pack 2 is connected in series via several battery spring plates 65, and the positive and negative ends of the battery pack 2 are pressed against the other ends of the battery negative terminal connector 63 and the battery positive terminal connector 64.

[0017] The battery negative terminal connector 63 is connected to the negative terminal end of the battery pack 2 by a spring protrusion. The spring wire at the other end of the battery negative terminal connector 63 is correspondingly pressed into the bottom input end of the power PCB board 61. This is mainly because the bottom of the power PCB board 61 is nested in the box 1, which can simultaneously and reliably press the spring wire at the other end of the battery negative terminal connector 63 into place.

[0018] The positive terminal connector 64 of the battery is connected to the positive terminal end of the battery pack 2 by a planar spring coil. The spring wire at the other end of the positive terminal connector 64 is correspondingly pressed into the bottom input end of the power PCB board 61. Similarly, the spring wire at the other end of the positive terminal connector 64 can be reliably pressed into the box 1 by the bottom of the power PCB board 61 being nested inside the box 1.

[0019] This utility model adopts a power supply circuit connection structure 6, in which all components are connected by elastic parts and are securely nested with the housing 1, achieving zero-wire harness transmission of the power supply signal. This effectively reduces the poor soldering or wire harness defects caused by traditional wire harness connections. The elastic pressing structure of the components reduces product costs and facilitates subsequent after-sales maintenance and replacement, making it suitable for the promotion and use of compact structure products.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
