Description

Technical Field

[0001] This utility model relates to the field of toy building blocks, and in particular to a battery box for a building block car with a PH2.0 socket. Background Technology

[0002] With the improvement of living standards, building block products have become common in ordinary households. Since the users of building block cars are children, the feel of assembling each circuit connector is very important. If the assembly points are too tight, children will not have enough strength to fasten them, and if they are too loose, the contact points may not make good contact.

[0003] Currently, the circuit contact terminals of a typical building block car consist of a plug and a socket. The plug terminal includes an upper cover, a lower cover, a 4-pin ribbon cable, and contact springs. The upper cover has a through contact spring with a concave surface design, which can be used as a socket. The lower cover has a through contact spring with a convex surface design, which can be used as a plug. The original control board has four sockets. The contact terminals need to be inserted into the sockets on the main board box. The sockets have a tight-fitting structure. After being inserted vertically into place, the power is supplied by the contact pins on the socket making contact with the contact pieces on the contact terminals. If the same set of signal outputs is required, another contact terminal can be connected in parallel with the contact terminals.

[0004] The drawbacks of the aforementioned traditional building block car contact terminals are as follows: due to the use of vertical insertion for fixing, the plug and socket need to be tightly fitted. If they are too loose, they are prone to poor contact or falling out. If they are too tight, they are inconvenient to assemble. The mold precision requirements are very high, and the contact pieces also require special tools for pressurization and assembly. The production process is complicated. The contact spring and the pin are in lateral contact, which requires high-quality spring material. The spring deformation of its contact surface is only about 0.3mm. It needs to be fully installed in place during assembly to make full contact, which is inconvenient for assembly. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned technical problems and provide a building block car battery box with a PH2.0 socket (the PH2.0 socket is a strip connector that conforms to the PH series standard, with a spacing of 2.0mm, a rated current of 3A, and features stable insertion and prevention of misinsertion). This application aims to solve the problems of poor contact and difficult assembly in the prior art by using a standardized PH2.0 socket.

[0006] A battery box for a building block car with a PH2.0 socket includes a box body, a circuit board, and a PH2.0 socket. The PH2.0 socket is fixed on the circuit board and includes a pair of 2.0-2P sockets (2P means the PH2.0 socket has two pins), a pair of 2.0-3P sockets (3P means the PH2.0 socket has three pins), and a pair of 2.0-4P sockets (4P means the PH2.0 socket has four pins). The box body has a plug-in surface with two plug interfaces. The circuit board is fixed in the box body, such that each plug interface has a 2.0-2P socket, a 2.0-3P socket, and a 2.0-4P socket arranged side by side. The 2.0-2P socket is used for electrical connection to the drive motor of the building block car, the 2.0-3P socket is used for electrical connection to the lights of the building block car, and the 2.0-4P socket is used for electrical connection to the steering motor of the building block car.

[0007] According to the battery box for a building block car with a PH2.0 socket in this application, the PH2.0 socket, also known as a PH strip connector, is a standardized socket. Utilizing mature PH2.0 socket technology simplifies the production process and reduces costs. The PH2.0 socket makes it easy to plug and unplug external plug wires. The contact stability is independent of the assembly force, mainly relying on the pins in the PH2.0 socket and the contact springs in the plug wire for fixation. The contact surface is very stable, making it easy for children to operate. During the building block car's operation, the contact between the PH2.0 socket and the plug wire will not loosen due to vibration. Different types of PH2.0 sockets are used for components with different functions. This type of socket design can eliminate the risk of incorrect function insertion.

[0008] Furthermore, the box body includes an upper cover and a base. The upper cover covers the base to form an installation cavity. The circuit board is installed in the installation cavity. The plug interface is provided on the upper cover. The circuit board is provided with a charging port and function buttons. The upper cover is provided with corresponding button caps and a charging port.

[0009] Furthermore, the two insertion ports are respectively located on the left and right sides of the top cover.

[0010] Furthermore, it also includes a separator and a battery, the battery being installed in the mounting cavity, and the separator being disposed between the battery and the circuit board. Attached Figure Description

[0015] The present invention relates to a battery box for a building block car with a PH2.0 socket, described in conjunction with the accompanying drawings.

[0016] like Figures 1 to 4 The illustrated building block car battery box includes a box body 1, a circuit board 2, and a PH2.0 socket 3. The technical parameters of the PH2.0 socket 3 are as follows:

[0017] Rated current: 3A, Rated voltage: 250V, Contact resistance: Initial value ≤20mΩ, Withstand voltage: For the connector in its combined state, apply 800V AC voltage to each of the ends of two adjacent conductors for 1 minute, and the leakage current must be less than 0.5mA, with no breakdown or sparking, Insulation resistance: For the connector in its combined state, apply 500V DC voltage to the ends of two adjacent contact conductors for 1 minute, and the insulation resistance value during the measurement period is ≥1000mΩ.

[0018] Utilizing mature PH2.0 socket technology, the production process is simplified and costs are reduced. The PH2.0 socket 3 is fixed on the circuit board 2. The PH2.0 socket 3 includes a pair of 2.0-2P sockets 31, a pair of 2.0-3P sockets 32, and a pair of 2.0-4P sockets 33. The housing 1 has a plug-in surface with two plug interfaces 111. The circuit board 2 is fixed in the housing 1, such that each plug interface 111 is provided with one 2.0-2P socket 31, one 2.0-3P socket 32, and one 2.0-4P socket 33 arranged side by side. The 2.0-2P socket 31 is used for electrical connection with the drive motor of the building block car, and the 2.0-3P socket... 32 is used for electrical connection with the lights of the building block car, and the 2.0-4P socket 33 is used for electrical connection with the steering motor of the building block car. Different types of PH2.0 sockets 3 are used for different functions of the components. This type of socket design can eliminate the risk of incorrect function plugging. For the drive motor, it only has a simple power supply requirement. The forward or backward movement of the drive motor can be controlled by the forward or reverse current. Therefore, the drive motor can be powered by a 2.0-2P socket with only two pins. For the lights or steering motors, they have more signal requirements. Therefore, in addition to using a 2.0-4P socket for power supply, the steering motor can also meet more signal interaction, thereby realizing the steering function of the steering motor.

[0019] like Figures 1 to 4As shown, the 2.0-2P socket 31 has two pins 34, which are connected to the drive motor plug wire 41 with two built-in contact springs. This allows the drive motor of the building block car to be electrically connected to the battery box, enabling the building block car to move forward and backward. The 2.0-3P socket 32 ​​has three pins 34, which are connected to the lamp plug wire 42 with three built-in contact springs. This allows the car lights of the building block car to be powered, making the building block car more realistic, playable, and simulation-worthy. LED lights are preferred. The 2.0-4P socket 33 has four pins 34, which are connected to the steering motor plug wire 43 with four built-in contact springs. This allows the steering motor of the building block car to be electrically connected to the battery box, enabling the building block car to turn. The PH2.0 socket 3 facilitates easy insertion and removal of the external plug cable 4. Contact stability is independent of assembly force, primarily relying on the pins 34 in the PH2.0 socket 3 and the contact springs in the plug cable 4 for fixation. The contact surface is highly stable, making it easy for children to operate. During the car's operation, vibrations will not loosen the contact between the PH2.0 socket 3 and the plug cable 4. After vibration testing, the connector soldered circuit board with the plug cable and socket in their combined state was used as a test sample, and vibration resistance testing was conducted according to the following specifications:

[0020] Frequency: 10-55-10 Hz / minute

[0021] Amplitude: 1.5mm pp (peak to peak)

[0022] direction:

[0023] 1. Vertical axis (Y-axis)

[0024] 2. Left and right axes (X-axis)

[0025] 3. Front and rear axial direction (Z-axis)

[0026] Cycle: 2 hours per axis

[0027] During the test, determine whether discontinuous current (power outage) occurs, and measure the contact resistance value after the test.

[0028] Test results: No damage to appearance, contact resistance ≤30mΩ, current interruption: 1μsec Max (maximum current interruption of 1 microsecond), meeting the stability requirements of signal transmission for the building block car.

[0029] like Figure 1 , Figure 3 as well as Figure 4As shown, the housing 1 includes an upper cover 11 and a base 12. The upper cover 11 covers the base 12 to form a mounting cavity 13. The circuit board 2 is installed in the mounting cavity 13. The plug interface 111 is provided on the upper cover 11. The circuit board 2 is provided with a charging port 22 and a function button 21. The upper cover 11 is correspondingly provided with a button cap 112 and a charging port 113. A screw fixing post 121 is provided at the corner of the base 12. The upper cover 11 is provided with a first screw fixing hole at the corresponding position. The upper cover 11 and the base 12 are connected and fixed by screws, screw fixing posts 121 and screw fixing holes. It also includes a partition 5 and a battery 6. The battery 6 is installed in the mounting cavity 13. In cavity 13, the partition 5 is disposed between battery 6 and circuit board 2. Battery 6 is placed at the bottom of the inner cavity of base 12. The partition 5 is provided with a first through hole 51. Circuit board 2 is provided with a second through hole 23 corresponding to the position of the first through hole 51. The upper cover 11 is provided with a second screw fixing hole at the corresponding position. By passing screws through the first through hole 51 and the second through hole 23 and fixing them with the second screw fixing hole, the partition 5 and circuit board 2 are stably fixedly installed at the bottom of the upper cover 11, and the PH2.0 socket 3, function button 21 and charging port 22 on circuit board 2 correspond to the plug interface 111, button cap 112 and charging port 113 on the upper cover 11.

[0030] like Figures 1 to 4 As shown, the two connectors 111 are respectively located on the left and right sides of the top cover 11. Generally, a building block car has a drive motor, a steering motor, and lights at the front and rear. The connectors 111 are located on the left and right sides, so that the PH2.0 socket 3 corresponds to the left and right sides of the building block car's battery box, thereby allowing the drive motor, steering motor, and lights at the front and rear of the building block car to be easily connected to the battery box.

[0031] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
