Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a model aircraft connector. Background Technology

[0002] To facilitate safe carrying and transportation, model airplanes typically have their wings detached from the fuselage to prevent damage. Connectors are installed between the fuselage and wings to facilitate communication, power supply, and control between them.

[0003] Model aircraft configurations may vary, resulting in differences in the number of sensors and controllers on the wings. These sensors and controllers communicate, are powered, and are controlled via connectors. Ordinary connectors generally cannot be augmented with additional terminals. Therefore, adding more connectors to a model aircraft requires increasing the number of connectors to meet the requirements. This leads to a less compact connector and wiring layout and increases costs.

[0004] For example, the power connector for model aircraft disclosed in Chinese patent application number CN201921859203.0 has a one-to-one correspondence between the male and female connectors. This type of connector cannot flexibly configure the terminals. After adding configuration, the only way to meet the requirements is to increase the number of connectors. This will make the layout of connectors and wiring in the model aircraft not compact and will increase the cost. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a model aircraft connector whose terminal modules can be flexibly configured; not only is the layout of the connector and wiring compact, which helps to reduce costs, but it also overcomes the shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This application provides a model aircraft connector, including a first terminal module, a first housing, a second terminal module, and a second housing; a first channel is provided inside the first housing; a first limiting groove is provided on the first terminal module; the first terminal module is inserted into the first channel, and a first limiting rib provided on the inner wall of the first channel is embedded in the first limiting groove; a second channel is provided inside the second housing; a first limiting step is provided on the second terminal module; a second limiting step is provided on the inner wall of the second channel; the second terminal module extends out from the second channel, and the second limiting step is blocked on the first limiting step; a spring piece on the second housing abuts against the second terminal module; the second terminal module is inserted into the first channel, and the first terminal module and the second terminal module are electrically connected.

[0008] Preferably, the second housing includes a main body and a frame; the main body and the frame are integrally formed, and a gap is left between the main body and the frame; the spring extends from the frame and can press against the back of the second terminal module.

[0009] Preferably, the frame structure is frame-shaped, and the frame and the main body are connected by at least two connecting parts.

[0010] Preferably, the inner wall of the first channel is provided with a second limiting rib, which can block the front end of the second terminal module.

[0011] Preferably, the inner wall of the first channel is provided with a third limiting rib, which can block the front end of the first terminal module.

[0012] Preferably, the first housing is provided with a first mounting ear; a first screw passes through the first mounting ear and fixes the first housing to the machine body;

[0013] The second housing is provided with a second mounting lug; a second screw passes through the second mounting lug and fixes the second housing to the wing.

[0014] Preferably, the first outer casing is provided with a first screw hole, and a first screw passes through the body and is screwed into the first screw hole; the second outer casing is provided with a second screw hole, and a second screw passes through the body and is screwed into the second screw hole.

[0015] Preferably, there are four first channels and four second channels; each first channel contains a first terminal module; and at least one second channel contains a second terminal module.

[0016] Preferably, the length of the first channel is greater than the length of the second channel, and the length of the second terminal module inserted into the first channel is not less than one-third of the length of the first channel.

[0017] Preferably, the first outer shell and the second outer shell are insulating plastic shells; the first terminal module and the second terminal module are injection molded terminal modules.

[0018] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, the first outer shell is provided with two or more first channels, and a first terminal module can be inserted into the first outer shell as needed. The second outer shell is provided with two or more second channels, and a second terminal module can be inserted into the second outer shell as needed. When the configuration of the model aircraft is increased, only the number of first terminal modules and second terminal modules needs to be increased or decreased accordingly. This design makes the layout of the connectors and wiring of the model aircraft more cost-effective.

[0019] When the first terminal module is inserted into the first channel, the first limiting rib provided on the inner wall of the first channel is embedded in the first limiting groove, so that the first terminal module is fixed and will not loosen.

[0020] The second terminal module extends from the second channel and inserts into the first channel, establishing electrical connection between the two modules. Moving the spring tab outward releases the second terminal module, allowing it to be easily removed. This design makes disassembly of the second terminal module very convenient. Conversely, when the second terminal is in place in the second channel, the second limiting step blocks the first limiting step; the spring tab on the second housing rests against the second terminal module, preventing it from becoming loose. This assembly method is very convenient and efficient. Attached Figure Description

[0032] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0033] Example 1

[0034] Please refer to Figures 1 to 6 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a model aircraft connector.

[0035] The first terminal module 120 can be set inside the first housing 110 as needed, and the second terminal module can also be set inside the second housing as needed. This design can reduce the number of connectors, reduce costs, and make the connectors and wiring more compact, which is beneficial for space layout.

[0036] This application provides a model aircraft connector, comprising a first terminal module 120, a first housing 110, a second terminal module 220, and a second housing 210; a first channel 112 is provided inside the first housing 110; a first limiting groove 121 is provided on the first terminal module 120; the first terminal module 120 is inserted into the first channel 112, and a first limiting rib 114 provided on the inner wall of the first channel 112 is embedded in the first limiting groove 121; a second channel 215 is provided inside the second housing 210; a first limiting step 221 is provided on the second terminal module 220; a second limiting step 216 is provided on the inner wall of the second channel 215; the second terminal module 220 extends out from the second channel 215, and the second limiting step 216 blocks the first limiting step 221; a spring piece 217 on the second housing 210 abuts against the second terminal module 220; the second terminal module 220 is inserted into the first channel 112, and the first terminal module and the second terminal module 220 are electrically connected. The first outer shell 110 and the second outer shell 210 are preferably insulating shells, manufactured using injection molding. The first outer shell 110 has two or more first channels 112, or it can have only one. The second outer shell 210 has two or more second channels 215, or it can have only one. In this embodiment, there are four first channels 112 and four second channels 215. Therefore, four first terminal modules 120 can be inserted into the first shell, and four terminal modules can also be inserted into the second shell. During assembly, the first terminal modules 120 can be inserted into all four first channels 112 firstly, and the second terminal modules 220 can be installed in the second channels 215 as needed. This assembly method is just one example; the specific method can be determined according to requirements.

[0037] When the first terminal module 120 is inserted into the first channel 112, the first limiting rib 114 provided on the inner wall of the first channel 112 is embedded into the first limiting groove 121 on the first terminal module 120, so that the first terminal module 120 is fixed in the first channel 112 and will not loosen. When the second terminal module 220 passes through the second channel 215, the second limiting step 216 blocks the first limiting step 221, and the spring piece 217 on the second housing 210 abuts against the second terminal module 220, so that the second terminal module 220 is fixed in the second channel 215. It can be seen that the assembly method of the second terminal module 220 is very simple and efficient. When the second terminal module 220 is inserted into the first channel 112, the first terminal module and the second terminal module 220 can conduct electricity.

[0038] Preferably, the second housing 210 includes a main body 212 and a frame 214; the main body 212 and the frame 214 are integrally formed, and a gap is left between the main body 212 and the frame 214; the spring piece 217 extends from the frame 214 and can abut against the back of the second terminal module 220. The spring piece 217 is inclined inward and can abut against the back of the second terminal module 220, thus confining the terminal module within the second channel 215. The spring piece 217 can abut against one second terminal module or simultaneously hold multiple second terminal modules. The gap between the main body 212 and the frame 214 allows the spring piece 217 to be moved by hand or screwdriver, thus releasing the back of the second terminal module and allowing the second terminal module to exit from the second channel 215. Therefore, the disassembly of the second terminal module is very convenient. Conversely, simply push the second terminal module into the second channel 215. Once the second terminal module is in place, the spring 217 will automatically press against the back of the second terminal module. This assembly structure is very simple and efficient.

[0039] Preferably, the frame portion 214 has a frame-like structure, and at least two connecting portions 213 connect the frame portion 214 to the main body portion 212. The frame portion 214 and the main body portion 212 are injection molded into a single unit, and the connecting portions 213 are plate-shaped. In this embodiment, the frame portion 214 and the main body portion 212 are connected by three connecting portions 213, which enhances the strength of the connection between the frame portion 214 and the main body portion 212.

[0040] For preferred options, please refer to [the provided text]. Figure 6 As shown, a second limiting rib 115 is provided on the inner wall of the first channel 112, which can stop the front end of the second terminal module 220. The second limiting rib 115 can control the insertion amount of the second terminal module 220 in the first channel 112, ensuring that the second terminal module 220 is inserted in place. The first terminal module 120 is provided with a first chamfer 123, which can reserve space for the second limiting rib 115 to avoid it.

[0041] For preferred options, please refer to [the provided text]. Figure 7 As shown, a third limiting rib 117 is provided on the inner wall of the first channel 112, which can stop the front end of the first terminal module 120. The third limiting rib 117 can control the position of the first terminal module 120 within the first channel 112. The second terminal module 220 is provided with a second chamfer 223, which can provide clearance for the third limiting rib 117. The third limiting step 124 on the first terminal module 120 also provides positioning for the first terminal module 120.

[0042] Preferably, the first housing 110 is provided with a first mounting ear 111; a first screw passes through the first mounting ear 111 and fixes the first housing 110 to the fuselage 310; the second housing 210 is provided with a second mounting ear 211; a second screw passes through the second mounting ear 211 and fixes the second housing 210 to the wing 311. The first housing 110 is inserted into the fuselage 310, and then the first screw locks the first housing 110 to the fuselage 310. The second housing 210 is inserted into the wing 311, and then the second screw locks the second housing 210 to the wing 311. This assembly method is very convenient and efficient.

[0043] Preferably, there are four first channels 112 and two channels 215; each first channel 112 contains a first terminal module 120; and at least one second channel 215 contains a second terminal module 220. Preferably, all first channels 112 contain first terminal modules 120, and the second channels 215 can be used to insert second terminal modules 220 as needed. This design is very flexible and facilitates the upgrading and optimization of the wing 311.

[0044] Preferably, the length of the first channel 112 is greater than the length of the second channel 215, and the length of the second terminal module 220 inserted into the first channel 112 is not less than one-third of the length of the first channel 112. This design can improve the rigidity between the first and second shells and improve the bending resistance of the connection between the wing 311 and the fuselage 310.

[0045] Preferably, the first outer shell 110 and the second outer shell 210 are insulating plastic shells; the first terminal module and the second terminal module 220 are injection-molded terminal modules. The injection-molded terminal module includes conductive terminals and an insulating body, with the conductive terminals injection-molded into the insulating body. An injection-molded terminal module is an electronic connector assembly manufactured using injection molding technology, primarily used to connect wires to electronic equipment. The conductive terminals have conductive ends and wiring ends, with wires soldered to the wiring ends. The conductive ends can make contact and conduct electricity.

[0046] Example 2

[0047] The structures of Embodiment 1 and Embodiment 2 are largely the same; the identical parts will not be described again. The differences are as follows: Please refer to... Figure 8-9As shown, the first outer casing 110 has a first screw hole 116, through which a first screw passes and is screwed into the first screw hole 116; the second outer casing 210 has a second screw hole 218, through which a second screw passes and is screwed into the second screw hole 218. The first outer casing 110 is inserted into the casing 310, and then the first screw is inserted into the casing and screwed into the first screw hole 116, completing the installation of the first outer casing 110. The second outer casing 210 is inserted into the casing 310, and then the second screw is inserted into the casing and screwed into the second screw hole 218, completing the installation of the second outer casing 210. This assembly method is also simple and efficient.

[0048] In summary, the key design feature of this invention lies in the fact that the first housing 110 is provided with two or more first channels 112, into which a first terminal module 120 can be inserted as needed. The second housing 210 is provided with two or more second channels 215, into which a second terminal module 220 can be inserted as needed. When the model aircraft is equipped with additional features, only the number of first terminal modules 120 and second terminal modules 220 needs to be adjusted accordingly. This design facilitates cost reduction in the layout of the model aircraft's connectors and wiring.
