Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] During connector use, when the plug is not inserted, the conductive parts of the male terminal are directly exposed at the socket, posing a safety hazard of electric shock due to accidental contact by the user. Traditional finger-protection structures are mostly fixed shields, which can provide some protection. However, when the plug is inserted, the fixed structure may cause hard interference with the plug, affecting the smoothness of insertion and removal. It may even cause structural wear due to long-term friction, reducing the protective effect and the lifespan of the connector.

[0022] In view of this, the present invention provides a movable anti-touch finger connector assembly, which aims to reduce the risk of electric shock and improve the smoothness of plugging and unplugging.

[0023] Please see Figure 1 and Figure 2 The movable finger-proof connector assembly includes a male housing 1, a male terminal 2, a finger-proof element 3, a terminal retainer 4, and a female terminal 5. The male housing 1, male terminal 2, and finger-proof element 3 constitute part of the structure of the socket 100, while the terminal retainer 4 and female terminal 5 constitute part of the structure of the plug 200. The terminal retainer 4 can be integrally formed into the female housing of the plug 200, or it can be installed inside the female housing of the plug 200. The male terminal 2 is installed inside the male housing 1 by interference fit or snap-fit.

[0024] The male housing 1 has a socket 11 for inserting the terminal retainer 4. The first end 21 of the male terminal 2 is fixed inside the male housing 1 with the first end 21 facing the socket 11. The anti-touch finger body 31 can be movably sleeved around the male terminal 2 in a first direction. The female terminal 5 is installed inside the terminal retainer body 41. When the terminal retainer body 41 is inserted into the socket 11, it drives the anti-touch finger body 31 to move in the first direction, switching it from an anti-touch state with the first end 21 protruding to a retracted conductive state. At this time, the male terminal 2 and the female terminal 5 abut against each other to achieve conductivity. After the terminal retainer body 41 is pulled out, the anti-touch finger body 31 can automatically return to the anti-touch state, preventing the conductive part of the male terminal 2 from being exposed through physical shielding.

[0025] To achieve the driving connection and disengagement between the terminal holding body 41 and the anti-touch finger body 31, several connection methods exist. Method 1: Separable magnetic connection. Specifically, magnets that attract each other are provided on the opposite end faces of the terminal holding body 41 and the anti-touch finger body 31. When the terminal holding body 41 is inserted, the magnets attract each other, causing the anti-touch finger body 31 to move; when pulled out, the magnets separate. Method 2: Elastic snap-fit ​​connection. During the insertion of the terminal holding body 41, the snap-fit ​​structure automatically engages to achieve power transmission; when pulled out, the snap-fit ​​disengages under external force, ensuring smooth separation. Method 3: Connection achieved through the cooperation of an elastic pin and a pin hole. Specifically, a retractable elastic pin is provided on the terminal holding body 41, and a pin hole is provided at the corresponding position on the anti-touch finger body 31. When the terminal retaining body 41 is inserted to the preset position, the elastic pin engages with the pin hole under its own elastic force, causing the anti-touch finger body 31 to move synchronously. When pulled out, the terminal retaining body 41 applies a reverse force to the elastic pin, causing it to retract from the pin hole, thus separating the two. Method 4: The snap-fit ​​structure mentioned in subsequent implementations can be used, and a spring or other reset component can be added. When the terminal retaining body 41 is inserted, the reset component is compressed, and the anti-touch finger body 31 overcomes the elastic force of the reset component and moves to a conductive state. When the terminal retaining body 41 is pulled out, the reset component releases its elastic potential energy, pushing the anti-touch finger body 31 back to the anti-touch state. The specific connection method used can be selected based on the requirements for connection stability, ease of operation, and cost control in the actual application scenario. These structural designs effectively block the male terminal 2 when not connected by switching the movement of the anti-finger body 31, thus eliminating the risk of accidental contact from a physical perspective and improving safety. During the connection process, the terminal maintains the driving cooperation between the anti-finger body 41 and the anti-finger body 31, enabling the anti-finger body 31 to automatically retract.

[0026] Due to the movable design of the anti-touch finger body 31, not only can the anti-touch finger body 31 switch between the anti-touch state and the conductive state, but it also avoids hard interference with the plug 200, making the insertion and removal process smoother.

[0027] The movable finger-proof connector assembly provided in this embodiment includes a male housing 1, a male terminal 2, a finger-proof component 3, a terminal retainer 4, and a female terminal 5. The male housing 1 has a socket 11. The first end 21 of the male terminal 2 is disposed inside the male housing 1. The first end 21 of the male terminal 2 has a first end 21 surface facing the socket 11. The finger-proof component 3 includes a finger-proof body 31, which is movably sleeved around the male terminal 2 along a first direction. The terminal retainer 4 includes a terminal retainer body 41, and the female terminal 5 is installed inside the terminal retainer body 41. The terminal retainer body 41 is inserted into the socket 11 and drives the finger-proof body 31 to move along the first direction, so that the finger-proof body 31 switches between a finger-proof state extending relative to the first end 21 surface and a conductive state retracted relative to the first end 21 surface. In the finger-proof state, the male terminal 2 and the female terminal 5 are disengaged. In the conductive state, the male terminal 2 and the female terminal 5 abut. This embodiment of the invention, through the movable design of the anti-finger body 31, effectively shields the conductive portion of the male terminal 2 when the plug 200 is not inserted, reducing the safety hazard of accidental electric shock to the user and significantly improving the safety during connector use. Simultaneously, this movable structure can automatically switch to a conductive state via the drive of the terminal holding body 41 when the plug 200 is inserted, avoiding the hard interference that may occur between the traditional fixed anti-finger structure and the plug 200. This significantly improves the smoothness of insertion and removal operations, reduces frictional resistance during insertion and removal, lowers the risk of structural wear, and thus extends the overall service life of the connector.

[0028] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 4 To achieve positioning in both the anti-touch and conductive states, corresponding snap-fit ​​structures are provided on the anti-touch finger body 31 and the male housing 1. Specifically, the anti-touch finger body 31 has a first snap-fit ​​structure 32 at its front end in the first direction; the inner wall of the male housing 1 is provided with a second snap-fit ​​structure 12 and an abutment structure 13 spaced apart in the first direction, and the distance between the second snap-fit ​​structure 12 and the socket 11 is less than the distance between the abutment structure 13 and the socket 11; wherein, during the process of the terminal holding body 41 being inserted into the socket 11, the first snap-fit ​​structure 32 disengages from the second snap-fit ​​structure 12 and gradually approaches the abutment structure 13 until the first snap-fit ​​structure 32 abuts the structure 13; during the process of the terminal holding body 41 being pulled out of the socket 11, the first snap-fit ​​structure 32 disengages from the abutment structure 13 until it snaps into the second snap-fit ​​structure 12.

[0029] The working principle of the first locking structure 32, the second locking structure 12, and the abutment structure 13 is as follows: When the terminal holding body 41 is not inserted, the anti-touch finger body 31 is in an anti-touch state. At this time, the first locking structure 32 and the second locking structure 12 engage with each other, restricting the movement of the anti-touch finger body 31 away from the socket 11, ensuring that it stably blocks the first end 21 surface of the male terminal 2. When the terminal holding body 41 begins to be inserted into the socket 11 and comes into contact with the anti-touch finger body 31, as the insertion depth increases, the terminal holding body 41 applies a pushing force along the first direction to the anti-touch finger body 31, causing the first locking structure 32 to overcome the locking force between itself and the second locking structure 12 and gradually disengage, and the anti-touch finger body 31 begins to move along the first direction. When the anti-touch finger body 31 moves to a conductive state, the first snap-fit ​​structure 32 abuts against the abutting structure 13. The abutting structure 13 limits the anti-touch finger body 31, preventing it from moving excessively and affecting the normal contact between the male terminal 2 and the female terminal 5. At the same time, it can also prevent the anti-touch finger body 31 from colliding and being damaged with other structures inside the male housing 1.

[0030] Conversely, when the terminal holding body 41 is pulled out of the socket 11, the anti-touch finger body 31 moves in the opposite direction under the drive of the terminal holding body 41. The first locking structure 32 gradually moves away from the abutment mechanism and gradually approaches the second locking structure 12, and finally engages with the second locking structure 12 again, so that the anti-touch finger body 31 is stably maintained in the anti-touch state, and the conductive part of the male terminal 2 is blocked again.

[0031] This embodiment of the utility model, through the cooperation of the first snap-fit ​​structure 32, the second snap-fit ​​structure 12, and the abutment structure 13, can precisely control the position of the anti-touch finger body 31 in the anti-touch state and the conductive state, ensuring the reliability and stability of the switching between the two states, avoiding unexpected movement or shaking of the anti-touch finger body 31 during use, and improving the overall performance of the connector.

[0032] Furthermore, as can be seen from the embodiments of this utility model, in the conductive state, the first snap-fit ​​structure 32 and the abutment structure 13 only abut against each other, and the anti-touch finger 3 may still be driven by the terminal retainer 4 in the first direction and separate from the abutment structure 13. To achieve stability in this state, the male housing 1 of the socket 100 and the female housing of the plug 200 can be snap-fitted together, that is, an additional snap-fit ​​structure can be added. Since this utility model mainly focuses on the anti-touch function, the content regarding conductive stability will not be described in detail. For specific design, mature snap-fit ​​solutions of existing connectors can be referred to.

[0033] In some embodiments, please continue reading Figure 2 , Figure 3 and Figure 4To achieve locking and positioning in both the anti-touch and conductive states, the specific locking structure is as follows: The first locking structure 32 includes a first locking protrusion 321 and a second locking protrusion 322 protruding outwards from the anti-touch finger body 31, with the first locking protrusion 321 and the second locking protrusion 322 spaced apart in the direction surrounding the male terminal 2; The second locking structure 12 includes a third locking protrusion 121 and a fourth locking protrusion 122 protruding inwards from the anti-touch finger body 31, with the third locking protrusion 121 and the fourth locking protrusion 122 spaced apart in the direction surrounding the male terminal 2; wherein, in the anti-touch state, the first locking protrusion 321 and the third locking protrusion 121 engage with each other, and the second locking protrusion 322 and the fourth locking protrusion 122 abut against each other; in the conductive state, the first locking protrusion 321 and the second locking protrusion 322 abut against the abutment structure 13 respectively.

[0034] In the anti-touch state, the first latching protrusion 321 and the third latching protrusion 121 engage with each other, creating a mutual pulling force; the second latching protrusion 322 and the fourth latching protrusion 122 abut against each other, creating a mutual pushing force. Thus, the pulling force formed by the first latching protrusion 321 and the third latching protrusion 121, combined with the pushing force generated by the second latching protrusion 322 and the fourth latching protrusion 122, forms a bidirectional limiting effect on the anti-touch finger body 31, effectively preventing the anti-touch finger body 31 from displacing along the first direction without external force, ensuring that it is stably positioned in the anti-touch position blocking the first end 21 surface of the male terminal 2.

[0035] When the terminal holding body 41 is inserted into the socket 11 and pushes the anti-touch finger body 31 to move, the first locking protrusion 321 and the third locking protrusion 121 will slide relative to each other. As the anti-touch finger body 31 moves, the first locking protrusion 321 gradually disengages from the engagement range of the third locking protrusion 121, while the second locking protrusion 322 overcomes the blocking force of the fourth locking protrusion 122 and continues to move until the first locking protrusion 321 and the second locking protrusion 322 respectively abut against the abutment part. At this time, the anti-touch finger body 31 switches to the conductive state, and the male terminal 2 and the female terminal 5 can make smooth contact and achieve conductivity.

[0036] This embodiment of the utility model, by setting the first latching protrusion 321, the second latching protrusion 322, the third latching protrusion 121, and the fourth latching protrusion 122 in a staggered distribution, utilizes the dual cooperation of hooking and abutting to form a stable bidirectional limiting structure in the anti-touch state. It can prevent the anti-touch finger body 31 from accidentally retracting through the hooking pull of the first latching protrusion 321 and the third latching protrusion 121, and can also prevent it from moving forward unexpectedly by the abutting push of the second latching protrusion 322 and the fourth latching protrusion 122. Thus, it can ensure that the anti-touch finger body 31 reliably blocks the male terminal 2 when the plug 200 is not inserted. During the insertion of the plug 200, as the terminal holding body 41 is pushed, the engagement between the first latch 321 and the third latch 121 is gradually released, and the second latch 322 can also smoothly overcome the obstruction of the fourth latch 122, so that the anti-touch finger body 31 can smoothly switch from the anti-touch state to the conductive state. This latching structure design is simple and compact, and can achieve stable state switching without additional complex driving components, thus improving the practicality and reliability of the connector assembly.

[0037] In some embodiments, please continue reading Figure 2 , Figure 3 and Figure 4 To achieve a driveable and separable connection between the terminal holding body 41 and the anti-touch finger body 31, a snap-fit ​​structure is added to both the terminal holding body 41 and the anti-touch finger body 31. Specifically, the end of the terminal holding body 41 used for insertion into the socket 11 is provided with a third snap-fit ​​structure 42; the end of the anti-touch finger body 31 used for extending from the first end 21 is provided with a fourth snap-fit ​​structure 34; wherein, during the process of the terminal holding body 41 driving the anti-touch finger body 31 to move along a first direction, the third snap-fit ​​structure 42 snaps into the fourth snap-fit ​​structure 34.

[0038] The engagement of the third locking structure 42 and the fourth locking structure 34 ensures that the terminal retaining body 41 can stably drive the anti-touch finger body 31 to move along the first direction during insertion. Specifically, when the terminal retaining body 41 is inserted into the socket 11 and comes into contact with the anti-touch finger body 31, the third locking structure 42 and the fourth locking structure 34 gradually align and engage with each other, forming a stable connection. As the terminal retaining body 41 continues to be inserted, this engagement transmits driving force, ensuring that the anti-touch finger body 31 moves synchronously under the drive of the terminal retaining body 41, thereby achieving the switching from the anti-touch state to the conductive state. When a certain external force is applied to separate the terminal from the body and pull it out, the engagement force between the third locking structure 42 and the fourth locking structure 34 can be overcome. The two gradually disengage from the engagement state. At this time, the anti-touch finger body 31 loses driving force, and the first locking structure 32 and the second locking structure 12 re-engage, causing the anti-touch finger body 31 to quickly return to the anti-touch state and continue to block the conductive part of the male terminal 2.

[0039] This embodiment of the utility model, through the setting of the third snap-fit ​​structure 42 and the fourth snap-fit ​​structure 34, not only ensures the connection stability when the terminal holding body 41 drives the anti-touch finger body 31 to move, but also enables the smooth separation of the two during the pull-out process, ensuring the reliable realization of the automatic reset function of the anti-touch finger body 31, and further improving the safety and ease of use of the movable anti-touch finger connector assembly.

[0040] In some embodiments, please continue reading Figure 2 , Figure 3 and Figure 4 To enable the terminal retainer 4 to both engage with and disengage from the anti-touch finger member 3, the engagement structure of the two has been optimized. Specifically, the fifth latching protrusion 421 has two bevels facing opposite directions in the first direction; and / or, the sixth latching protrusion 341 has two bevels facing opposite directions in the first direction.

[0041] When the terminal retaining body 41 is inserted, the fifth latching protrusion 421 contacts the sixth latching protrusion 341. The two inclined surfaces of the fifth latching protrusion 421 and the six latching protrusion 341 cooperate with each other, and the guiding effect of the inclined surfaces causes the fifth latching protrusion 421 and the six latching protrusion 341 to slide relative to each other. During the sliding process, the fifth latching protrusion 421 and the six latching protrusion 341 undergo elastic deformation, thereby enabling them to engage smoothly. When the terminal retaining body 41 is pulled out, the two inclined surfaces of the fifth latching protrusion 421 and the six latching protrusion 341, in the opposite direction, again play a guiding role, causing the fifth latching protrusion 421 and the six latching protrusion 341 to gradually disengage under the action of elastic restoring force, thus achieving separation.

[0042] This embodiment of the invention utilizes the inclined surfaces of the fifth latching protrusion 421 and the sixth latching protrusion 341. When the terminal holding body 41 is inserted, the inclined surfaces guide the latching protrusions to elastically deform and engage, ensuring stable transmission of driving force. When withdrawn, the reverse inclined surfaces guide the latching protrusions to elastically reset and disengage, allowing the terminal holding body 41 to smoothly separate from the anti-touch finger body 31. This design eliminates the need for additional operations to complete the engagement and disengagement, improving the convenience of the insertion and removal process.

[0043] In some embodiments, please continue reading Figure 2 , Figure 3 and Figure 4To ensure that the terminal holding body 41 stably drives the movement of the anti-touch finger member 3, the anti-touch finger member 3 and the terminal holding member 4 have been optimized. Specifically, the third locking structure 42 includes a fifth locking protrusion 421 protruding inward to the anti-touch finger body 31, and the fourth locking structure 34 includes a sixth locking protrusion 341 extending outward to the anti-touch finger body 31. During the process of the terminal holding body 41 driving the anti-touch finger body 31 to move along the first direction, the fifth locking protrusion 421 and the sixth locking protrusion 341 engage with each other. The end of the terminal holding body 41 used for inserting into the socket 11 is also provided with a pressing protrusion 43, and the outer wall of the anti-touch finger body 31 is provided with a lever structure 33. During the process of the terminal holding body 41 driving the anti-touch finger body 31 to move along the first direction, the pressing protrusion 43 abuts against the lever structure 33.

[0044] During the movement of the anti-touch finger body 31 driven by the terminal holding body, the third locking structure 42 and the fourth locking structure 34 are connected to each other, thereby generating a mutual pulling force; the pressing protrusion 43 and the lever structure 33 abut against each other, thereby forming a mutual pushing force. This pulling force and pushing force work together on the anti-touch finger body 31 to build a stable driving force transmission mechanism.

[0045] This embodiment of the utility model can effectively avoid the slippage or insufficient driving force problems that may occur in a single snap-fit ​​structure through this dual-drive design, and ensure that the anti-finger body 31 moves smoothly along the first direction under the drive of the terminal holding body 41.

[0046] In some embodiments, please continue reading Figure 2 , Figure 3 and Figure 4 To ensure that the second locking protrusion 322 can smoothly pass over the fourth locking protrusion 122, and that both the first locking protrusion 321 and the second locking protrusion 322 abut against the abutment structure 13, the lever structure 33 was optimized. For details, please refer to... Figure 5 The lever structure 33 includes a lever body 331 and a support portion 332 connected to the outer wall of the anti-finger-touch body 31. The lever body 331 extends along a first direction and has a first lever end 3311 and a second lever end 3312. The second lever end 3312 has a second locking protrusion 322. The pressing protrusion 43 presses the first lever end 3311 outward to move the second locking protrusion 322 on the second lever end 3312 inward and over the fourth locking protrusion 122.

[0047] When the terminal retaining body 41 is inserted into the socket 11 and pushes the anti-touch finger body 31 to move, the pressing protrusion 43 first contacts the first lever end 3311 of the lever structure 33. As the terminal retaining body 41 continues to be inserted, the pressing protrusion 43 applies an outward pressing force to the first lever end 3311, causing the lever body 331 to rotate around the support part 332 as a fulcrum. During this stage, the second locking protrusion 322, connected to the second lever end 3312, moves inward toward the anti-touch finger body 31 under the action of the lever principle. At the same time, due to the pushing force along the first direction, the second locking protrusion 322 can successfully overcome the obstruction of the fourth locking protrusion 122. After the second locking protrusion 322 has completely passed the fourth locking protrusion 122, the anti-touch finger body 31 can continue to move along the first direction until it abuts against the abutment structure 13, thereby realizing the transition from the anti-touch state to the conductive state. This optimized design of the lever structure 33, through ingenious mechanical transmission, transforms the insertion action of the terminal retaining body 41 into the avoidance movement of the second latch 322, effectively solving the interference problem between the second latch 322 and the fourth latch 122, and ensuring the smoothness of the state switching process.

[0048] This embodiment of the invention utilizes the optimized design of the lever structure 33 to convert the linear motion of the terminal retaining body 41 during insertion into a radial avoidance motion of the second locking protrusion 322. This allows the second locking protrusion 322 to easily overcome the obstruction of the fourth locking protrusion 122, avoiding the jamming or structural damage problems caused by hard collisions in traditional structures. Furthermore, this design can be achieved simply by setting the lever structure 33 on the outer wall of the anti-finger-touch body 31 and the pressing protrusion 43 at the end of the terminal retaining body 41, eliminating the need for additional complex drive components, simplifying the overall structure, and reducing manufacturing costs.

[0049] In some embodiments, please refer to Figure 4 and Figure 5 To ensure that a small inward displacement of the first lever end 3311 can cause a larger inward displacement of the second lever end 3312, the positions of the first lever end 3311 and the second lever end 3312 are defined. Specifically, the distance between the end face of the first lever end 3311 and the support portion 332 is smaller than the distance between the end face of the second lever end 3312 and the support portion 332.

[0050] According to the lever principle, the longer the lever arm, the greater the displacement under the same force. By setting the distance between the second lever end 3312 and the support part 332 to be greater than the distance between the first lever end 3311 and the support part 332, when the first lever end 3311 is subjected to a small pushing force from the compression protrusion 43, the second lever end 3312 can generate a larger radial displacement, thereby driving the second locking protrusion 322 to move inward a sufficient distance to ensure that it smoothly passes the fourth locking protrusion 122.

[0051] This embodiment of the utility model optimizes the transmission efficiency of the lever structure 33 through this differentiated design of lever arm length. While ensuring the avoidance effect of the second locking protrusion 322, it reduces the thrust requirement of the squeezing protrusion 43, making the insertion and extraction process more effortless.

[0052] In some embodiments, please continue reading Figure 4 and Figure 5 To ensure that the first lever end 3311 is gradually expanded and to avoid abrupt deformation, the first lever end 3311 has been optimized accordingly. Specifically, the first lever end 3311 is provided with a spreading protrusion 3313, which protrudes inward toward the anti-finger-touch body 31. The end of the spreading protrusion 3313 facing away from the second lever end 3312 forms a spreading inclined surface 33131. In the inward direction, the distance between the spreading inclined surface 33131 and the outer wall surface of the anti-finger-touch body 31 gradually decreases.

[0053] When the terminal retaining body 41 is inserted, its end first contacts the spreading ramp 33131 of the spreading protrusion 3313. Since the distance between the spreading ramp 33131 and the outer wall of the anti-touch finger body 31 gradually decreases inwards, the terminal retaining body 41 slides relative to the spreading protrusion 3313 through this ramp during insertion. As the insertion depth increases, the compressive force on the spreading ramp 33131 gradually increases, allowing the first lever end 3311 to smoothly spread outwards, preventing sudden deformation or damage to the lever structure 33 due to excessive instantaneous force.

[0054] This embodiment of the invention provides a spreading protrusion 3313 with a spreading inclined surface 33131 at the first lever end 3311. Utilizing the gradual change in the inclined surface, the extrusion force is smoothly transmitted, allowing the first lever end 3311 to gradually spread outwards during the insertion of the terminal holding body 41. This avoids the problem of concentrated instantaneous impact force caused by traditional right-angle or straight-face contact. This design not only effectively protects the lever structure 33 but also extends its service life.

[0055] In some embodiments, please continue reading Figure 4 and Figure 5 To ensure that the extrusion protrusion 43 does not extend to the side of the expansion protrusion 3313 away from the insertion port 11 after being extruded and spread out, but only remains on the outer side of the expansion protrusion 3313, the structure of the extrusion protrusion 43 has been optimized. Specifically, in the first direction, the width of the end of the extrusion protrusion 43 is smaller than the width of the root of the extrusion protrusion 43.

[0056] This design allows the end of the pressing protrusion 43 to smoothly act on the spreading slope 33131 when it contacts and applies pressure to the spreading protrusion 3313, while the wider root structure limits the pressing protrusion 43 from extending excessively into the anti-touch finger body 31. When the terminal holding body 41 is inserted into place, the head or root of the pressing protrusion 43 abuts against the outer side of the spreading protrusion 3313, preventing it from extending beyond the spreading protrusion 3313 to the side away from the socket 11. This ensures that in the conductive state, the pressing protrusion 43 remains only on the outer side of the spreading protrusion 3313 and does not interfere with the reset movement of the anti-touch finger body 31.

[0057] This embodiment of the utility model, through a differentiated design of the width of the extrusion protrusion 43, ensures that it effectively extrudes and expands the protrusion 3313 while achieving precise positioning of its own position, further improving the stability and reliability of the connector assembly insertion and removal process.
