Description

Technical Field

[0001] The invention relates to the technical field of connectors, in particular to a novel direct-insertion locking connection mechanism. Background Art

[0002] With the development of aerospace science and technology, the requirements for lightweight and automated equipment are becoming higher and higher, and the space for connector operation is also shrinking. The traditional separation and removal of electrical connectors (unplugging) connection mechanism uses a handwheel lock, which requires a large operating space and needs to be reset before plugging in. The operation is cumbersome and has gradually failed to meet the needs of the new generation of equipment. Summary of the invention

[0003] The purpose to be achieved by the present invention is to provide a novel direct-insertion locking connection mechanism, which solves the problem of complicated operation and inability to automatically reset in the prior art, realizes automatic reset and makes the operation simpler.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a novel plug-in locking connection mechanism, comprising a plug and a socket, the socket is provided with a locking groove, the plug comprises a push rod, a connecting sleeve, a first steel ball and a driving assembly, the push rod is provided with a first inclined surface, the connecting sleeve is sleeved outside the push rod, the connecting sleeve is provided with a first through hole in the radial direction, the first steel ball is installed in the first through hole, a first spring is installed between the push rod and the connecting sleeve, a sheath and a second spring are provided on the outer sleeve of the connecting sleeve, one end of the second spring is connected to the sheath, the other end of the second spring is provided with a first transmission member that moves synchronously, the push rod is provided with a second transmission member that moves synchronously, and the driving assembly is used to lock at least one of the first transmission member and the second transmission member in a set position or unlock;

[0005] The plug is inserted into the socket, the driving assembly locks at least one of the first transmission member and the second transmission member at a set position, the sheath is acted upon by an external force to overcome the elastic force of the second spring and move backward to open the first through hole, the first spring pushes the push rod forward to move it forward, and the first inclined surface of the push rod presses the first steel ball into the locking groove to achieve locking;

[0006] When the driving component unlocks the first transmission member and the second transmission member, the second spring pushes the second transmission member backward through the first transmission member to drive the connecting sleeve to move backward, and the first steel ball is disengaged from the locking groove to achieve unlocking. At the same time, the second spring pushes the sleeve forward to move forward and close the first through hole.

[0007] After adopting the above technical scheme, the present invention has the following advantages: it adopts a direct plug-in design, and locking and unlocking are achieved through the internal mechanical structure. The entire plugging and unplugging process is more direct and simple, without complicated and redundant actions, and does not require a large rotation space like a traditional hand wheel. It can be used in a more compact space, which is in line with the development trend of lightweight and miniaturization of modern aerospace equipment. When unlocking, the second spring pushes the second transmission member backward through the first transmission member to drive the connecting sleeve to move backward, and the first steel ball is disengaged from the locking groove to achieve unlocking. At the same time, the second spring pushes the sleeve forward to move forward and close the first through hole. No manual reset is required, making the entire connection and disconnection process faster and more efficient.

[0008] Furthermore, the driving assembly includes a locking sleeve, an unlocking sleeve, a second steel ball and a driving member, the locking sleeve is radially provided with a second through hole, the second steel ball is installed in the second through hole, the locking sleeve is sleeved on the unlocking sleeve and is axially fixed relative to the connecting sleeve, the unlocking sleeve is provided with a second inclined surface, the driving member and the unlocking sleeve are transmission-connected, the driving member drives the unlocking sleeve to move so that different parts of the second inclined surface contact the second steel ball, so that the second steel ball switches between a first position where it is pushed outward to lock the first transmission member at a set position and a second position where it is retracted to unlock the first transmission member.

[0009] By adopting the above-mentioned technical solution, the position of the unlocking sleeve is controlled by the driving member so that different parts of the second inclined surface contact the second steel ball, thereby accurately controlling whether the second steel ball is pushed outward or retracted inward, and automatically completing the locking and unlocking actions without manual resetting or performing complicated operating steps.

[0010] Furthermore, the driving member includes a corrugated spring, an armature and a coil, the armature is slidably connected to the connecting sleeve and fixedly connected to the unlocking sleeve, the corrugated spring is sleeved on the outside of the armature, and when the coil is energized, the coil attracts the armature through electromagnetic force to drive the unlocking sleeve to move.

[0011] By adopting the above technical solution, the electromagnetic drive can respond to the electrical signal quickly. Once the coil is energized, the electromagnetic force generated will immediately attract the armature to move, thereby driving the unlocking sleeve to quickly complete the locking or unlocking action.

[0012] Furthermore, the wire package is electrically connected to a terminal, and the terminal is at least partially exposed outside the plug.

[0013] With the aforementioned technical solution, the exposed design of the terminal allows the user to conveniently make electrical connections to the terminal.

[0014] Furthermore, the driving member includes a pull rod and a third spring, the pull rod is provided with a first limiting step, the third spring is sleeved on the pull rod, the third spring rests on the first limiting step and the shell of the plug, the pull rod and the unlocking sleeve are transmission connected, the pull rod is pulled by external force to overcome the elastic force of the third spring to drive the unlocking sleeve to move.

[0015] Through the above technical solution, the unlocking sleeve can be moved by pulling the pull rod with external force, which provides flexibility of manual operation and realizes multiple unlocking methods. This is very useful for application scenarios that require rapid on-site response or operation without power supply.

[0016] Furthermore, the socket is provided with an abutment portion, and the plug is pushed forward so that the sheath abuts against the abutment portion to overcome the elastic force of the second spring and move backward.

[0017] Through the above technical solution, the sheath can be moved backward by simply pushing the plug forward, thereby triggering the locking mechanism, thereby improving the convenience of use.

[0018] Furthermore, the first transmission member is a transmission sleeve, and a fourth spring is sleeved on the outer side of the transmission sleeve. The first transmission member has a tendency to keep moving forward under the elastic force of the fourth spring, and the elastic force of the fourth spring is greater than that of the second spring.

[0019] Through the above technical solution, the function of the fourth spring is to keep the first transmission member moving forward. When the elastic force of the second spring is restored, the fourth spring will overcome the elastic force of the second spring and drive the first transmission member to return to the set position without manual reset.

[0020] Furthermore, the connecting sleeve is provided with a movable groove for the first transmission member and / or the second transmission member to move and to enable the two to contact each other, and the inner wall of the movable groove is used to limit the maximum movement of the first transmission member and / or the second transmission member.

[0021] Through the above technical solution, the inner wall of the movable groove clearly defines the maximum movement of the first transmission member and / or the second transmission member, ensuring that they move within a predetermined range, which helps prevent mechanical damage or functional failure caused by excessive movement. When the first transmission member and / or the second transmission member reaches the limit position of the movable groove, it will be blocked by the inner wall, resulting in a significant change in resistance. This provides clear operational feedback to the operator, confirming that the first transmission member and / or the second transmission member has reached the predetermined position.

[0022] Furthermore, a protective sleeve is provided on the outer periphery of the connecting sleeve, the second spring, the first transmission member and the fourth spring, and a second limiting step is provided on the protective sleeve, and the first transmission member abuts against the second limiting step to limit the forward movement of the first transmission member.

[0023] Through the above technical solution, the protective sleeve can limit the radial deformation of the second spring and the fourth spring, and prevent the second spring and the fourth spring from arching when compressed or stretched. The second limit step clearly defines the maximum forward displacement of the first transmission member, ensuring that it moves within a predetermined range, which helps to maintain the stability and reliability of the connector.

[0024] Furthermore, a third limiting step is provided on the inner wall of the connecting sleeve, and a stopping step is provided on the push rod, and the third limiting step abuts against the stopping step to limit the forward movement of the push rod.

[0025] Through the above technical solution, the cooperation between the third limiting step and the stop step clearly defines the maximum forward movement of the ejector rod, ensuring that it moves within a predetermined range, which helps to maintain the stability and reliability of the connector.

[0035] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0036] like Figure 1 and Figure 2As shown, the present invention provides a novel plug-in locking connection mechanism, including a plug 100 and a socket 200, the socket 200 is provided with a locking groove 210, the plug 100 includes a push rod 110, a connecting sleeve 120, a first steel ball 130 and a driving assembly, the push rod 110 is provided with a first inclined surface 111, the connecting sleeve 120 is sleeved outside the push rod 110, the connecting sleeve 120 is provided with a first through hole 121 in the radial direction, the first steel ball 130 is installed in the first through hole 121, and a first spring 130 is installed between the push rod 110 and the connecting sleeve 120. 50, the first spring 150 always applies a forward thrust to the push rod 110, the outer sleeve 160 and the second spring 152 are provided on the connecting sleeve 120, one end of the second spring 152 is connected to the sleeve 160, the other end of the second spring 152 is provided with a first transmission member 170 that moves synchronously, and the push rod 110 is provided with a second transmission member 180 that moves synchronously, the driving assembly is used to lock the first transmission member 170 at a set position or unlock it, and the second transmission member 180 always maintains a tendency to move forward under the thrust of the first spring 150;

[0037] The plug 100 is inserted into the socket 200, and the driving assembly locks at least one of the first transmission member 170 and the second transmission member 180 in a set position. The sheath 160 is acted upon by an external force to overcome the elastic force of the second spring 152 and move backward so that the sheath 160 is disengaged from the first through hole 121. The first spring 150 pushes the push rod 110 forward to move it forward, and the first inclined surface 111 of the push rod 110 presses the first steel ball 130 into the locking groove 210 to achieve locking.

[0038] When the driving assembly unlocks the first transmission member 170 and the second transmission member 180, the second spring 152 pushes the second transmission member 180 backward through the first transmission member 170 to drive the connecting sleeve 120 to move backward, so that the first steel ball 130 disengages from the locking groove 210 to achieve unlocking. At the same time, the second spring 152 pushes the sleeve 160 forward to move forward and close the first through hole 121.

[0039] A straight-plug design is adopted, and locking and unlocking are achieved through an internal mechanical structure. The entire plug-in and unplugging process is more direct and simple, without complicated and redundant actions. It also does not require a large rotation space like a traditional hand wheel, and can be used in a more compact space, which is in line with the development trend of lightweight and miniaturization of modern aerospace equipment. When unlocking, the second spring 152 pushes the second transmission member 180 backward through the first transmission member 170 to drive the connecting sleeve 120 to move backward, and the first steel ball 130 is disengaged from the locking groove 210 to achieve unlocking. At the same time, the second spring 152 pushes the sleeve 160 forward to move forward and close the first through hole 121. No manual reset is required, making the entire connection and disconnection process faster and more efficient.

[0040] The socket 200 is provided with an abutment portion 220, and the plug 100 is pushed forward so that the sheath 160 abuts against the abutment portion 220 to overcome the elastic force of the second spring 152 and move backward. By simply pushing the plug 100 forward, the sheath 160 can be moved backward, thereby triggering the locking mechanism, which improves the convenience of use.

[0041] In order to unlock the first transmission member 170 and the second transmission member 180, the second spring 152 pushes the sheath 160 forward to move forward and close the first through hole 121. The first transmission member 170 is a transmission sleeve, and the outer side of the transmission sleeve is sleeved with a fourth spring 153. The first transmission member 170 has a tendency to keep moving forward under the elastic force of the fourth spring 153, and the elastic force of the fourth spring 153 is greater than that of the second spring 152. The function of the fourth spring 153 is to keep the first transmission member 170 moving forward. When the elastic force of the second spring 152 is restored, the fourth spring 153 will overcome the elastic force of the second spring 152 and drive the first transmission member 170 to return to the set position without manual reset.

[0042] In order to realize the linkage between the connecting sleeve 120 and the push rod 110, the connecting sleeve 120 is provided with an active groove 122 for the second transmission member 180 to move. The second transmission member 180 passes through the active groove 122 and contacts the first transmission member 170. The inner wall of the active groove 122 is used to limit the maximum movement of the second transmission member 180. The inner wall of the active groove 122 clearly defines the maximum movement of the second transmission member 180, ensuring that they move within a predetermined range, which helps to prevent mechanical damage or functional failure caused by excessive movement. When the second transmission member 180 reaches the limit position of the active groove 122, it will be blocked by the inner wall of the active groove 122, resulting in a significant change in resistance. This provides clear operational feedback for the operator to confirm that the second transmission member 180 has reached the predetermined position. The second transmission member 180 includes a collar sleeved outside the connecting sleeve 120 and a connecting rod for connecting the collar and the push rod 110. The collar is radially provided with a perforation, and the connecting rod is inserted into the perforation and connected to the push rod 110.

[0043] The driving assembly includes a locking sleeve 140, an unlocking sleeve 141, a second steel ball 142 and a driving member. The locking sleeve 140 is provided with a second through hole 1401 in the radial direction. The second steel ball 142 is installed in the second through hole 1401. The locking sleeve 140 is sleeved on the unlocking sleeve 141 and is axially fixed relative to the connecting sleeve 120. The unlocking sleeve 141 is provided with a second inclined surface 1411. The driving member and the unlocking sleeve 141 are connected in a transmission manner. The driving member drives the unlocking sleeve 141 to move so that different parts of the second inclined surface 1411 contact with the second steel ball 142, so that the second steel ball 142 switches between a first position in which the first transmission member 170 is pushed outward to lock the first transmission member 170 at a set position and a second position in which the second steel ball 142 is retracted to unlock the first transmission member 170. The position of the unlocking sleeve 141 is controlled by the driving member so that different parts of the second inclined surface 1411 contact with the second steel ball 142, thereby accurately controlling whether the second steel ball 142 is pushed outward or retracted inward, and automatically completing the locking and unlocking actions without manual resetting or performing complicated operation steps.

[0044] Specifically, the driving member includes a wave spring 143, an armature 144 and a wire package 145. The armature 144 is slidably connected to the connecting sleeve 120 and fixedly connected to the unlocking sleeve 141. The wave spring 143 is sleeved on the outside of the armature 144. When the wire package 145 is powered on, the wire package 145 attracts the armature 144 through electromagnetic force to drive the unlocking sleeve 141 to move. Electromagnetic drive can respond quickly to electrical signals. Once the wire package 145 is powered on, the electromagnetic force generated will immediately attract the armature 144 to move, thereby driving the unlocking sleeve 141 to quickly complete the locking or unlocking action.

[0045] To facilitate wiring, the wire package 145 is electrically connected to a terminal 1451, and the terminal 1451 is at least partially exposed outside the plug 100. The exposed design of the terminal 1451 allows the user to easily make an electrical connection to the terminal 1451, thereby facilitating connection to an external power source.

[0046] In order to provide multiple unlocking modes, the driving member includes a pull rod 146 and a third spring 147. The pull rod 146 is provided with a first limiting step 1461. The third spring 147 is sleeved on the pull rod 146. The third spring 147 abuts against the first limiting step 1461 and the housing of the plug 100. The pull rod 146 is in transmission connection with the unlocking sleeve 141. The pull rod 146 is pulled by an external force to overcome the elastic force of the third spring 147 to drive the unlocking sleeve 141 to move. The unlocking sleeve 141 can be moved by pulling the pull rod 146 by an external force, which provides flexibility of manual operation and realizes multiple unlocking modes, which is very useful for application scenarios that require rapid response on site or operation without power supply.

[0047] In this embodiment, the armature 144 and the pull rod 146 are fixedly connected via a pin 148 to achieve a transmission connection between the pull rod 146 and the unlocking sleeve 141 .

[0048] In order to maintain the stability of the connector, a protective sleeve 190 is provided on the outer periphery of the connecting sleeve 120, the second spring 152, the first transmission member 170 and the fourth spring 153. A second limiting step 191 is provided on the protective sleeve 190. The first transmission member 170 abuts against the second limiting step 191 to limit the forward movement of the first transmission member 170. The protective sleeve 190 can limit the radial deformation of the second spring 152 and the fourth spring 153, and prevent the second spring 152 and the fourth spring 153 from arching when compressed or stretched. The second limiting step 191 clearly defines the maximum forward movement of the first transmission member 170, ensuring that it moves within a predetermined range, which helps to maintain the stability and reliability of the connector.

[0049] Furthermore, the inner wall of the connecting sleeve 120 is provided with a third limiting step 123, and the top rod 110 is provided with a stop step 112, and the third limiting step 123 abuts against the stop step 112 to limit the forward movement of the top rod 110. The cooperation between the third limiting step 123 and the stop step 112 clearly defines the maximum forward movement of the top rod 110, ensuring that it moves within a predetermined range. This helps to maintain the stability and reliability of the connector.

[0050] During use, when plugged in, the sleeve 160 first touches the abutment portion 220 of the socket 200, the sleeve 160 moves, compresses the second spring 152, the first through hole 121 opens, the first spring 150 pushes the push rod 110 to move forward, and the first steel ball 130 in the connecting sleeve 120 enters the locking groove 210 under the action of the first inclined surface 111 of the push rod 110, and the direct plug-in locking connection mechanism completes the locking.

[0051] Principle of electrical separation and unlocking: the terminal 1451 is connected to the power supply, and after a voltage of 28V±3V is passed to the wire package 145, the wire package 145 attracts the armature 144, and the armature 144 drives the unlocking sleeve 141 to move at the same time under the attraction of the electromagnetic force of the wire package 145, thereby releasing the restriction of the second steel ball 142 at the first transmission member 170. At this time, the rebound force of the second spring 152 is greater than the elastic force of the fourth spring 153, and the first transmission member 170 hits the second transmission member 180, and the second transmission member 180 drives the ejector rod 110 to move in the opposite direction of the insertion. When the inclined surface of the ejector rod 110 contacts the second steel ball 142, the second steel ball 142 enters the first inclined surface 111 of the ejector rod 110, and the socket 200 loses its restrictive effect on the first steel ball 130, and the direct plug-in locking connection mechanism is unlocked and separated. At this time, the fourth spring 153 and the second spring 152 are both in a compressed state, but the elastic force of the fourth spring 153 is greater than that of the second spring 152, and the first spring 150 acts on the second spring 152 through the top rod 110, the second transmission member 180, and the first transmission member 170, so the sheath 160 tends to move forward and finally completes the reset action under the obstruction of the second limit step 191.

[0052] Mechanical separation and unlocking separation principle: During mechanical separation, a separation force of 40N to 80N is applied to the pull rod 146, and the pull rod 146 moves backward. After pulling the armature 144, the armature 144 and the unlocking sleeve 141 move simultaneously, releasing the restriction of the second steel ball 142 at the first transmission member 170. At this time, the rebound force of the second spring 152 is greater than the elastic force of the fourth spring 153, and the first transmission member 170 hits the second transmission member 180, and the second transmission member 180 drives the push rod 110 to move in the opposite direction of the insertion. When the first inclined surface 111 of the push rod 110 contacts the first steel ball 130, the first steel ball 130 enters the first inclined surface 111 of the push rod 110, and the socket 200 loses its restrictive effect on the first steel ball 130, and the direct plug-in locking connection mechanism is unlocked and separated.

[0053] It is understandable that in other embodiments, only the corrugated spring, the armature and the coil may be provided to realize electric unlocking, or only the pull rod and the third spring may be provided to realize manual unlocking.

[0054] It can be understood that in other embodiments, the drive assembly is used to lock the first transmission member and the second transmission member at a set position or unlock them at the same time to prevent the first transmission member and the second transmission member from moving when locked.

[0055] It can be understood that in other embodiments, the drive assembly is used to lock the second transmission member at a set position or unlock it, and the first transmission member is always subject to the elastic force of the second spring to maintain a forward trend.

[0056] It is understandable that in other embodiments, the connecting sleeve is provided with a movable groove for the first transmission member to move, the first transmission member passes through the movable groove and contacts the second transmission member, and the inner wall of the movable groove is used to limit the maximum movement of the first transmission member. The inner wall of the movable groove clearly defines the maximum movement of the first transmission member, ensuring that they move within a predetermined range, which helps to prevent mechanical damage or functional failure caused by excessive movement. When the first transmission member reaches the limit position of the movable groove, it will be blocked by the inner wall of the movable groove, resulting in a significant change in resistance. This provides clear operational feedback to the operator to confirm that the first transmission member has reached the predetermined position. Of course, the first transmission member and the second transmission member can also be moved simultaneously.

[0057] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
