Description

Technical Field

[0001] This utility model relates to the field of toy parts, and in particular to an expansion-type terminal block for a remote control toy control handle. Background Technology

[0002] The control handle is used by users to control the actions of remote-controlled toys. For professional remote-controlled toy enthusiasts, the internal circuitry of the control handle often requires data adjustments, and sometimes expansion modules need to be connected to the control handle. Therefore, wiring is necessary. However, existing wiring methods are very primitive. Some involve an external wire extending directly from inside the control handle, which affects the feel of operation and is easily damaged. Others use terminals installed in the control handle, but because the terminal installation is only a simple plug-in connection, it is not secure and is very easy to fall off. Therefore, it is necessary to design an expansion-type terminal. Utility Model Content

[0003] To address the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide an expansion-type terminal block that is easy to connect to electricity and can be expanded and tightened for installation.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] An expandable terminal block for a remote control toy control handle includes a terminal block body made of a single conductive material. The top of the terminal block body is a wiring section with a wiring groove on the outer wall for connecting wires. The lower part of the terminal block body is an expansion section, which is divided into several pins by a slatted design. A through-hole is provided in the middle of the terminal block body. An expansion pin is also provided above the terminal block body to support the pins. The inner hole and the expansion pin are fastened together by threads.

[0006] Furthermore, the present invention has multiple wiring grooves evenly distributed on the wiring part, and the wiring grooves can be connected by winding wires.

[0007] Furthermore, the inner wall of the plug in this invention is provided with an expansion flange that allows the expansion nail to press against the external support, and a tapered chamfer is provided at the lower end of the expansion nail body for contacting the expansion flange.

[0008] Furthermore, the outer wall of the plug in this invention is provided with a backward scraping protrusion for preventing it from falling off during installation.

[0009] Furthermore, the lower end of the expansion portion in this utility model is provided with an edge chamfer.

[0010] Furthermore, in this invention, the thread covers the top of the expansion nail body and the top of the inner hole.

[0011] Furthermore, the expansion nail in this invention has an anti-slip texture on the outer periphery of the nail head, and an internal hexagonal screw hole is provided on the top of the nail head.

[0012] Furthermore, the side of the wiring portion in this utility model is provided with an inner groove for welding reinforcement.

[0013] In summary, the advantages of this utility model over the prior art are:

[0014] The terminal block of this utility model has conductive properties and can be internally connected to the internal circuit of the control handle, resulting in excellent power transmission. Furthermore, the expansion pins allow the expansion portion to expand and securely install itself on the control handle, preventing it from falling off and maintaining a long-term connection. Since the expansion pins are installed via a threaded connection, they can be unscrewed after expansion installation, allowing for easy installation and removal. Attached Figure Description

[0016] Figure 2 This is a three-dimensional exploded view of the present invention;

[0017] Figure 3 This is a three-dimensional sectional view of the present invention. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1 to 3 The present invention preferably provides an expandable terminal block for a remote control toy control handle, comprising a terminal block body 1, the terminal block body 1 being made of an integral conductive material, the top of the terminal block body 1 being a wiring part 2, the outer wall being provided with a wiring groove 21 for connecting wires, the lower part of the terminal block body 1 being an expansion part 3, which is divided into several pins 32 by setting a quincunx groove 31, a through inner hole 4 being provided in the middle of the terminal block body 1, and an expansion pin 5 being provided above the terminal block body 1 to support the pins 32 externally, the inner hole 4 and the expansion pin 5 being fastened together by threads.

[0020] The control handle has a hole for inserting the terminal block. After insertion, screwing in the expansion pin into the inner hole causes the lower end of the expansion pin to push open the pins, thus expanding and fixing the terminal block to the control handle. Since the expansion pin and the inner hole are threaded, the expansion state is locked by tightening the expansion pin. Similarly, unscrewing the expansion pin releases the expansion state of the terminal block, allowing it to be removed. The wiring section can be used to wrap wires, allowing external devices or other modules to be connected to the internal circuitry of the control handle.

[0021] In this invention, multiple wiring slots 21 are provided and evenly distributed on the wiring section 2. The wiring slots 21 can be connected by winding wires. The core of the wire is wound into the wiring slot to connect external devices or modules to the internal circuitry of the control handle.

[0022] In this invention, an expansion flange 33 is provided on the inner wall of the pin 32, which allows the expansion pin 5 to press against the outer support. A tapered chamfer 51 is provided at the lower end of the expansion pin 5 for contacting the expansion flange 33. Since the expansion flange protrudes from the inner hole, the expansion flange can be pressed outward by the lower end of the screwed-in expansion pin, thereby expanding the pin.

[0023] In this invention, a backward-scraping protrusion 34 is provided on the outer wall of the pin 32 for preventing detachment during installation. The backward-scraping protrusion allows the pin to grip the inner wall of the hole in the operating handle after expansion, thereby achieving a stable installation and fixation.

[0024] In this invention, the lower end of the expansion part 3 is provided with an edge chamfer 35. The edge chamfer facilitates insertion into the hole provided in the operating handle.

[0025] In this invention, the thread covers the top of the expansion nail 5 and the top of the inner hole 4. The threaded connection allows the expansion nail to be screwed in or out.

[0026] In this invention, the expansion nail 5 has anti-slip texture 52 around its head, and an internal hexagon screw hole 53 on the top of its head. This allows users to easily unscrew the expansion nail by hand or with a tool.

[0027] In this invention, an inner groove 22 for welding reinforcement is provided on the side of the wiring portion 2. This inner groove allows the wiring terminal body to be fixed to the operating handle through the welding point.

[0028] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
