Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a plug-in module and a rotating plug. Background Technology

[0002] Rotary plugs have two modes: an engaged position and a retractable position. When in use, the plug is in the engaged position for insertion into the socket. When not in use, the plug is in the retractable position to reduce the size of the plug for easy storage and to reduce safety hazards. They are widely used in daily life.

[0003] The rotary plug is also equipped with a positioning spring. Under the action of the positioning spring, the pins are kept relatively stable in the plug-in position and the receiving position. In order to prevent short circuits caused by contact between the positioning spring and the rotary plug, the positioning spring is generally made of plastic. However, in actual use, the plug must undergo aging tests in a high-temperature environment before leaving the factory. After the test, the plastic positioning spring will age, deform and weaken in elasticity, which is insufficient to guarantee the stability of the pins in the plug-in position and the receiving position. Moreover, the damping effect is weakened when rotating the pins, affecting the feel of use. Utility Model Content

Detailed Implementation

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] This utility model embodiment provides a plug-in module, such as Figures 1 to 7 As shown, the device includes a mounting housing 10, a pin assembly 20, and a positioning spring 30. The pin assembly 20 includes a rotating shaft 210, a first pin 220, and a second pin 230. The rotating shaft 210 is rotatably disposed on one side of the mounting housing 10. The rotating shaft 210 includes a first conductive shaft 211, an insulating shaft 212, and a second conductive shaft 213 connected in sequence. The first pin 220 is sleeved on the first conductive shaft 211, and the second pin 230 is sleeved on the second conductive shaft 213. The rotating shaft 210 allows the first pin 220 to be positioned on the first conductive shaft 211. The pin 220 and the first pin 220 switch between the insertion position and the receiving position; the positioning spring 30 is provided on the mounting housing 10, the positioning spring 30 has an elastic arm 322 formed on it, and the insulating shaft 212 has a locking protrusion 2121 formed on it; when the first pin 220 and the second pin 230 are in the insertion position or the receiving position, the locking protrusion 2121 and the elastic arm 322 cooperate to limit the insulating part; wherein, the positioning spring 30 is made of metal material, and the mounting housing 10 is made of insulating material.

[0030] The mounting housing 10 is designed to provide a stable installation environment. The pin assembly 20 includes a rotating shaft 210, a first pin 220, and a second pin 230. The rotating shaft 210 is rotatably located on one side of the mounting housing 10. The rotating shaft 210 includes a first conductive shaft 211, an insulating shaft 212, and a second conductive shaft 213 connected in sequence. The first pin 220 is fitted onto the first conductive shaft 211, and the second pin 230 is fitted onto the second conductive shaft 213. Under the action of the rotating shaft 210, the first pin 220 can switch between a plug-in position and a receiving position to achieve different usage states. This is achieved by positioning the spring 30... The elastic arm 322 engages with the latch 2121 on the insulating shaft 212 to ensure that the first pin 220 and the second pin 230 remain relatively stable in the insertion and receiving positions. Meanwhile, the positioning spring 30 is made of metal material, which has good high-temperature stability. Therefore, when the insertion module is subjected to aging tests in a high-temperature environment before leaving the factory, the positioning spring 30 itself will not be affected by the high temperature. This ensures the stability of the elastic arm 322 of the positioning spring 30 for the first pin 220 and the second pin 230 in the insertion and receiving positions. Furthermore, the damping effect of the elastic arm 322 will not change during the rotation of the shaft 210, ensuring a good user experience.

[0031] The mounting housing 10 is made of insulating material, and the first pin 220 and the second pin 230 are isolated by an insulating shaft 212 to ensure their insulation. The first pin 220 and the second pin 230 are respectively connected to the first conductive shaft 211 and the second conductive shaft 213. This is to ensure that the first pin 220 and the second pin 230 are electrically connected independently, so as to realize the electrical working principle of the plug-in module. In this embodiment, the mounting housing 10 may be made of plastic.

[0032] As a preferred embodiment, the plug-in module further includes a cover plate 40, which is disposed on the mounting housing 10. The cover plate 40 can cover the plug assembly 20 and the positioning spring 30, and cooperates with the mounting housing 10 to limit the plug assembly 20 in the vertical direction; wherein, the cover plate 40 is made of insulating material.

[0033] The cover plate 40 and the mounting housing 10 limit the pin assembly 20 in the vertical direction to prevent the pin assembly 20 from being displaced in the vertical direction during rotation, so as to ensure the stability of the pin assembly 20 rotation.

[0034] The cover plate 40 is made of insulating material to prevent short circuits caused by contact between the cover plate 40 and the first pin 220 and the second pin 230, thereby realizing the electrical working principle of the plug-in module.

[0035] As a preferred embodiment, the positioning spring 30 is made of heat-treated manganese steel.

[0036] Manganese steel is a type of steel with a high manganese content, typically containing 10% to 14% manganese. The addition of manganese can improve the strength, hardness, and wear resistance of steel, but it also affects its toughness and elasticity. Pure manganese steel usually has lower toughness and elasticity because the addition of manganese increases its brittleness. Heat treatment is a method of altering the internal structure and properties of a metal, adjusting its microstructure through heating and cooling processes. For manganese steel, heat treatment can significantly improve its toughness and elasticity, ensuring the effective contact between the elastic arm 322 and the latch 2121 on the positioning spring 30. This further enhances the stable positioning of the positioning spring 30 on the first pin 220 and the second pin 230 in the insertion or receiving positions, as well as the damping effect and feel when rotating the pins.

[0037] As a preferred embodiment, refer to Figure 1 and Figure 2 The width of the positioning spring 30 matches the length of the insulating shaft 212.

[0038] In order to prevent the metal positioning spring 30 from contacting the first pin 220 and the second pin 230 during use, causing a short circuit between the first pin 220 and the second pin 230, the width of the positioning spring 30 is set to match the length of the insulating shaft 212. Therefore, when using the plug-in module, the positioning spring 30 only cooperates with the locking protrusion 2121 on the insulating shaft 212 to limit its movement, thus ensuring the stability of the plug-in module.

[0039] As a preferred embodiment, refer to Figures 1 to 5 ,as well as Figure 9 A first mounting groove 101 and a second mounting groove 102 are formed on one side of the mounting housing 10. The rotating shaft 210 is disposed in the first mounting groove 101. A first mounting post 1011 is disposed in the first mounting groove 101, and a second mounting post 1021 is disposed in the second mounting groove 102. Both ends of the positioning spring 30 and the cover plate 40 are disposed on the first mounting post 1011 and the second mounting post 1021 by fasteners 50. A first receiving groove 1 is formed on the side of the mounting housing 10 opposite to the first mounting groove 101. 03 and the second receiving groove 104, the first pin 220 and the second pin 230 are respectively located in the receiving position in the first receiving groove 103 and the second receiving groove 104; and the part of the first pin 220 and the part of the second pin 230 extend from the first receiving groove 103 and the second receiving groove 104 respectively; the mounting housing 10 is also provided with a positioning post 11, and the cover plate 40 is formed with a corresponding positioning hole 401. When the cover plate 40 is provided on the mounting housing 10, the positioning post 11 is located in the positioning hole 401.

[0040] In this embodiment, the pin assembly 20, positioning spring 30, and cover plate 40 are specifically arranged on the mounting housing 10. Specifically, a first mounting groove 101 and a second mounting groove 102 are formed on one side of the mounting housing 10. The rotating shaft 210 is rotatably disposed in the first mounting groove 101. A first mounting post 1011 is disposed in the first mounting groove 101. In the actual installation process, the two ends of the positioning spring 30 are first disposed on the first mounting post 1011 and the second mounting post 1021 respectively, and then the cover plate 40 is disposed on the mounting housing 10 so that the cover plate 40 can cover the pin assembly 20 and the positioning spring 30. When the cover plate 40 is disposed, the positioning hole 401 cooperates with the positioning post 11 disposed on the mounting housing 10 to quickly adapt the cover plate 40 to the mounting housing. The cover plate 40 and the positioning spring 30 are positioned on the body 10, and the fasteners 50 are respectively installed on the first mounting post 1011 and the second mounting post 1021 to fix the positioning spring 30 and the cover plate 40 on the mounting housing 10. In order to ensure the integration of the plug-in module when the first pin 220 and the second pin 230 are in the receiving position, a first receiving groove 103 and a second receiving groove 104 are formed on the side of the mounting housing 10 away from the first mounting groove 101. The first receiving groove 103 and the second receiving groove 104 provide a receiving environment for the first pin 220 and the second pin 230, which improves the integration of the plug-in module and protects the first pin 220 and the second pin 230, preventing damage to the first pin 220 and the second pin 230 caused by accidental force such as bumps.

[0041] The first pin 220 and the second pin 230 extend from the first receiving groove 103 and the second receiving groove 104 respectively. When using the plug-in module, with the first pin 220 and the second pin 230 respectively located within the first receiving groove 103 and the second receiving groove 104, the user can manipulate the first pin 220 and the second pin 230 by extending the portions of the first receiving groove 103 and the second receiving groove 104, causing the first pin 220 and the second pin 230 to rotate from the receiving position to the plug-in position. Similarly, manipulating the first pin 220 and the second pin 230 can change it from the plug-in position to the receiving position, thereby improving the ease of use of the plug-in module.

[0042] As a preferred embodiment, refer to Figure 8 The positioning spring 30 includes a first mounting part 310, a connecting part 320, and a second mounting part 330 connected in sequence. The first mounting part 310 is used to connect with the first mounting post 1011, and the second mounting part 330 is used to connect with the second mounting post 1021. A mounting notch 321 is formed on the connecting part 320, and an elastic arm 322 is provided on the connecting part 320 and extends along the mounting notch 321. The free end of the elastic arm 322 is located on the side close to the insulating shaft 212, and the connecting part 320 protrudes from the first mounting part 310 and the second mounting part 330.

[0043] In this design, a first mounting hole 3101 and a second mounting hole 3301 are formed on the first mounting portion 310 and the second mounting portion 330 of the positioning spring 30, respectively. A fastener 50 passes through the first mounting hole 3101 to fix the first mounting portion 310 to the first mounting post 1011, and another fastener 50 passes through the second mounting hole 3301 to fix the second mounting portion 330 to the second mounting post 1021. An elastic arm 322 is provided on the connecting portion 320. The elastic arm 322 extends along the mounting notch 321 and the free end of the elastic arm 322 is located on the side close to the insulating shaft 212. The elastic arm 322 can provide a supporting force to the latching protrusion 2121, thereby ensuring the stability of the rotating shaft 210 and making the first pin 220 and the second pin 230 maintain relative stability in the receiving position and the insertion position. The connecting portion 320 protrudes from the first mounting portion 310 and the second mounting portion 330. This structural design is reasonable and makes the supporting force of the elastic arm 322 on the latching protrusion 2121 more stable.

[0044] As a preferred embodiment, the positioning spring 30 is an integrally formed structure.

[0045] In this embodiment, the one-piece molding structure allows for better control of material performance and characteristics during the production process, resulting in higher strength and stability, reduced material fatigue and fracture risk, and thus ensuring the cooperation between the elastic arm 322 and the latch 2121 to limit the pin assembly 20.

[0046] As a preferred embodiment, refer to Figure 7 and Figure 9 A first positioning ring 2122 and a second positioning ring 2123 are also formed on the outer periphery of the insulating shaft 212. The first positioning ring 2122 and the second positioning ring 2123 are distributed on both sides of the locking protrusion 2121. A first limiting groove 1012 and a second limiting groove 1013 are also formed at the bottom of the first mounting groove 101. A portion of the first positioning ring 2122 can be located in the first limiting groove 1012, and a portion of the second positioning ring 2123 can be located in the second limiting groove 1013.

[0047] The engagement of the first positioning ring 2122 with the first limiting groove 1012 and the engagement of the second positioning ring 2123 with the second limiting groove 1013 are used to prevent the insulating shaft 212 from sliding along its axial direction on the mounting housing 10 during the rotation of the rotating shaft 210, thereby improving the stability and accuracy of the first pin 220 and the second pin 230 when switching between the insertion position and the receiving position.

[0048] As a preferred embodiment, refer to Figure 6 and Figure 7The plug-in module further includes: a conductive component 60, comprising a first conductive element 610 and a second conductive element 620. The first conductive element 610 includes a first sleeve ring 611 and a first clamping part 612 connected in sequence. The first sleeve ring 611 is rotatably sleeved on the first conductive shaft 211. The first wire 710 is fixed on the first clamping part 612, and the core of the first wire 710 is in contact with the first sleeve ring 611. The second conductive element 620 includes a second sleeve ring 621 and a second clamping part 622 connected in sequence. The second sleeve ring 621 is rotatably sleeved on the second conductive shaft 213. The second wire 720 is fixed on the second clamping part 622, and the core of the second wire 720 is in contact with the second sleeve ring 621.

[0049] The conductive component 60 is configured to connect the first pin 220 and the second pin 230 to the first wire 710 and the second wire 720 respectively, thereby realizing the electrical working principle of the plug-in module. Specifically, one end of the first conductive component 610 is rotatably connected to the first conductive shaft 211, and one end of the second conductive component 620 is rotatably connected to the second conductive shaft 213. During the rotation of the first pin 220 and the second pin 230 driven by the rotating shaft 210, the first conductive component 610 and the second conductive component 620 remain stationary, and the first wire 710 and the second wire 720 will not move with the rotation of the rotating shaft 210, preventing the first wire 710 and the second wire 720 from being damaged, and improving the service life and the stability of the electrical connection.

[0050] In practical applications, the first sleeve 611 is rotatably fitted onto the first conductive shaft 211. Therefore, during the rotation of the shaft 210, the first conductive element 610 can be kept stationary under the action of the first sleeve 611. The first clamping part 612 is used to fix the first wire 710 onto the first conductive element 610, improving the connection stability between the first wire 710 and the first conductive element 610. At the same time, the core of the first wire 710 is made to contact the first sleeve 611 so that the first wire 710 and the first conductive element 610 are electrically connected. Similarly, the second sleeve 621... The second conductive element 620 is rotatably sleeved on the second conductive shaft 213. Therefore, during the rotation of the shaft 210, the second sleeve ring 621 can keep the second conductive element 620 stationary. The second clamping part 622 is used to fix the second wire 720 on the second conductive element 620, thereby improving the connection stability between the second wire 720 and the second conductive element 620. At the same time, the core of the second wire 720 is made to contact the second sleeve ring 621 so that the second wire 720 and the second conductive element 620 are electrically connected, thereby realizing the electrical connection of the plug-in module in the plug-in position and ensuring the normal operation of the plug-in module.

[0051] In this embodiment, the first conductive shaft 211 and the second conductive shaft 213 are inserted on both sides of the insulating shaft 212. The first pin 220 abuts between the first conductive element 610 and the insulating shaft 212, and the second pin 230 abuts between the second conductive element 620 and the insulating shaft 212. This improves the stability of the first pin 220 and the second pin 230 on the rotating shaft 210.

[0052] This application also discloses a rotary plug, including a housing (not shown in the figure) and the plug-in module of the foregoing embodiments. This rotary plug has the same structure and beneficial effects as the plug-in module of the foregoing embodiments. The structure and beneficial effects of the plug-in module have been described in detail in the foregoing embodiments and will not be repeated here.
