Description

Technical Field

[0001] The present invention belongs to the technical field of connectors, and particularly relates to a detachable connector. Background Art

[0002] The existing detachable connector consists of a mating plug and socket, and the socket of the detachable connector is fixedly installed, while the plug is the free end connected to a cable. When mating, the plug needs to be inserted into the socket by hand to achieve mating. When separating, pulling the core shaft realizes automatic separation. The locking and positioning between the plug and the socket adopt a central pull rod locking mechanism, and its structural principle is as Figure 1 and Figure 2 shown: The central pull rod locking mechanism mainly consists of components such as a core shaft 101 assembled at the plug end, a core shaft sleeve 102, a pressure cylinder 103, steel balls 104, a pressure cylinder spring 105, and a locking ring 106 used in supporting the socket end; the core shaft 101 is guided and slidably assembled in the core shaft sleeve 102, and the pressure cylinder spring 105 and the pressure cylinder 103 are sequentially slidably sleeved on the core shaft sleeve 102. The working principle diagram is as Figure 1 shown: When the plug and the socket in the connector are in a separated state, the core shaft 101 (with a core shaft spring not shown in the figure at the tail) cooperates with the core shaft sleeve 102 and the pressure cylinder 103, so that multiple steel balls are evenly distributed in a circle on the core shaft sleeve; and the core shaft spring is in a compressed state when the plug and the socket are in a separated state, and has a rightward pushing force on the core shaft, but the core shaft cannot move to the right due to the blocking and matching of the steel ball 104 and the core shaft inclined surface. Combining Figure 2 , when mating, the pressure cylinder 103 moves leftward relative to the core shaft sleeve under the pushing action of the locking ring 106. When the steel ball 104 enters the position of the cut groove 107 of the locking ring, the steel ball 104 is pushed outward by the core shaft under the elastic force of the core shaft spring and is squeezed into the cut groove 107 of the locking ring, thereby realizing the locking function. When the plug and the socket are separated, the core shaft 101 moves leftward under the action of mechanical force, and at the same time, the steel ball 104 is squeezed inward by the pressure cylinder 103 under the action of the pressure cylinder spring 105 until the steel ball 104 is buried in the core shaft sleeve 102, thereby realizing the unlocking function.

[0003] When the connector is locked, only visual inspection of the core shaft position or the use of the mating feel can be relied on to confirm that the locking is in place. In a non-visual area with a narrow space or an area where the mechanical automatic docking cannot achieve the feel, it is impossible to confirm whether the locking is in place after the connector is mated. If the connector works in an unlocked state, it is easy to cause accidental separation and circuit interruption. And when manually pushing the plug to achieve mating and locking with the socket, when the number of cores of the connector is large, the mating resistance is large or in an environment where the space is narrow and the hands cannot reach, the mating will become very difficult. Summary of the Invention

[0004] The object of the present invention is to provide a detachable connector, which can provide an identification signal after the plug and the socket are inserted in place, so as to prevent circuit interruption caused by accidental separation, and does not require manual intervention during the insertion or separation process, and is suitable for the automatic operation of connectors in concealed occasions.

[0012] The aforementioned detachable connector, wherein the insulator includes an insulating base and an insulating pressing plate which are fastened together to fix the jack.

[0013] The aforementioned detachable connector, wherein the insulating base is a stepped structure composed of two cylinders with different outer diameters.

[0029] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0030] A specific embodiment of a detachable connector of the present invention, as Figures 3 to 9As shown in the figure, it includes a matching plug and socket. The plug includes a floating mounting component, a plug housing 201, a locking mechanism, and a locking recognition device installed inside the plug housing. The floating mounting component includes a floating plate 501 and a mounting plate 502. The mounting plate is used to fix the plug inside the device. The floating plate 501 is connected to the plug housing by a first floating screw 503. Both sides of the floating plate 501 have spring cylinders 505 for installing floating springs 504. A support cylinder 506 sleeved on the floating spring is guidingly and slidably assembled inside the spring cylinder 505. The mounting plate is connected to the floating plate by a second floating screw 507. The mounting plate is arranged above the spring cylinder and elastically abuts against the support cylinder. The first floating screw 503 has a clearance fit with the corresponding mounting hole on the floating plate both axially and radially. After the first floating screw passes through the floating plate and is tightened and fixed to the plug housing, the plug can float relative to the floating plate by a certain amount. The second floating screw 507 has a clearance fit with the corresponding mounting hole on the mounting plate axially. After the second floating screw passes through the mounting plate and is tightened and fixed to the floating plate, the floating plate can float axially relative to the mounting plate. The function of the floating spring is to always make the support cylinder abut against the mounting plate and give an upward elastic support force to the mounting plate, so that there is still a gap between the floating plate and the mounting plate after the plug and the socket are inserted, thus realizing the up and down floating of the floating plate relative to the mounting plate axially in the inserted state to adapt to the high-frequency vibration environment.

[0031] The locking mechanism includes a mandrel sleeve 301 fixed inside the plug housing 201 and a housing 302 sleeved outside the mandrel sleeve. A pressure cylinder 304 is guidingly and slidably assembled between the housing 302 and the mandrel sleeve 301 through a pressure cylinder spring 303. A mandrel 306 is guidingly and slidably assembled inside the mandrel sleeve 301 through a mandrel spring 305. The top end of the mandrel spring 305 abuts against the plug housing 201, and the bottom end abuts against the mandrel. A locking steel ball 307 is arranged in a radial through hole opened at the bottom end of the mandrel sleeve 301. When the plug and the socket are not inserted, the inner wall of the pressure cylinder 304 cooperates with the bottom inclined surface of the mandrel 306 to realize the radial limit of the locking steel ball. At this time, the locking steel ball and the bottom inclined surface of the mandrel are in a blocking fit, so that the mandrel spring 305 is in a compressed state, and the locking mechanism is in an unlocked state. Preferably, a limiting steel ball 309 for blocking and cooperating with the pressure cylinder to realize the axial movement limit of the pressure cylinder is also installed inside the mandrel sleeve 301. The mandrel is axially provided with a slideway 3061 for slidingly cooperating with the limiting steel ball and the locking steel ball.

[0032] The locking identification device 400 includes a fixed outer sleeve 401, an insulating sliding sleeve 402, a short-circuit pin 403, a spring 404, an insulator 405 and a jack 406. The fixed outer sleeve 401 is fixedly assembled on the plug housing 2. Preferably, the middle part of the fixed outer sleeve 401 has a flange 4011 detachably connected to the plug housing 2; the insulating sliding sleeve 402 is guided and slidably assembled at the inner top of the fixed outer sleeve 401, and the top of the insulating sliding sleeve 402 protrudes from the fixed outer sleeve 401. The top of the core shaft 306 sequentially passes through the plug housing and the floating plate and is fixedly connected to the cover plate 308. The cover plate 308 abuts against the top of the insulating sliding sleeve 402 to achieve transmission, that is, when the core shaft moves axially downward, the cover plate can be driven to press down the insulating sliding sleeve. The bottom end of the insulating sliding sleeve 402 is provided with a guiding hole 4021 extending axially upward, and the top end is provided with a mounting groove 4022. A short-circuit plate 407 with electrical conductivity is fixedly arranged in the mounting groove. Two short-circuit pins 403 are arranged in parallel in the insulating sliding sleeve. The middle part of the short-circuit pin 403 has a positioning step to facilitate cooperation with the corresponding step groove provided on the insulating sliding sleeve to achieve installation positioning. The top end of the short-circuit pin 403 passes through the short-circuit plate 407 and is fixedly welded to the short-circuit plate by solder 4031, so that when the locking mechanism is locked, the two short-circuit pins are electrically connected through the short-circuit plate. The bottom end of the short-circuit pin 403 extends to the bottom of the guiding hole 4021. When assembling the short-circuit pin, the short-circuit pin is first inserted into the insulating sliding sleeve from the bottom end to the top end direction and the positioning step is abutted and fitted with the corresponding step groove, and then the top end of the short-circuit pin is welded to the short-circuit plate to achieve further fixation. The insulator is fixedly assembled at the inner bottom end of the fixed outer sleeve 401. A jack 406 for plugging and electrically connecting with the short-circuit pin 403 is assembled in the insulator. Two jacks are arranged in parallel and are arranged corresponding to the short-circuit pins one by one; the top end of the jack is used for plugging with the pin, and the bottom end of the jack is a signal connection hole 4061 electrically connected to the corresponding signal receiving system. The signal connection hole 4061 can be connected to the corresponding signal receiving system through a signal line to send an electrical signal.

[0033] In this embodiment, the insulator 405 is composed of an insulating seat 408 and an insulating pressing plate 409 that are buckled together, and the two are buckled together to fix the jack 406. In this embodiment, the jack can be buckled by a conventional method of setting positioning steps on the insulating pressing plate and the insulating seat, but the present invention is not limited thereto. For example, bonding fixation can also be used. The insulating seat 408 is a stepped structure composed of two cylinders with different outer diameters. The small-diameter cylinder extends upward into the guiding hole 4021. A straight hole 4081 communicating with the jack 406 is opened at the top of the small-diameter cylinder. When the locking mechanism is in Figure 5 the unlocked state shown, the state of the locking identification device is as shown in Figure 8 ( Figure 5 、 Figure 9The middle flange 4011 is not shown). When the short-circuit pin 403 is already inserted into the straight hole 4081 but does not contact the socket 406, the straight hole 4081 mainly plays a role of pre-guiding the short-circuit pin, preventing the bending and damage caused by the pin hitting the top of the insulator when moving downward in a vibrating environment; when switching from the unlocking state to the locking state, the short-circuit pin 403 continues to move downward and inserts into the socket 406. An axially limiting shoulder 4012 is convexly provided on the inner wall of the fixed outer sleeve 401 to cooperate with the large-diameter cylinder for axial limiting during the installation of the insulating seat, and the shoulder 4012 is simultaneously abutted against the outer wall of the small-diameter cylinder to achieve radial limiting of the insulating seat. The bottom of the insulating pressing plate 409 is installed in the fixed outer sleeve through a retaining ring 410, and the cooperation between the shoulder and the retaining ring realizes the axial positioning of the insulator. The spring 404 is sleeved on the small-diameter cylinder of the insulating seat 408. The top end of the spring 404 is located inside the guiding hole and abuts against the top of the guiding hole of the insulating sliding sleeve 402, and the bottom end of the spring abuts against the shoulder 4012. The function of the spring is to give the insulating sliding sleeve a restoring force when the insulating sliding sleeve 402 is not subjected to the downward axial pressure of the cover plate 5, so as to realize the automatic conversion of the locking recognition device from the locking state to the unlocking state. Since the spring is located between the inner wall of the guiding hole 4021 and the outer wall of the insulating seat 408, it can guide and limit the spring during the axial compression process, increase the stability of the spring under repeated compression, and increase the working times of the locking recognition device.

[0034] The socket includes a socket housing 601 and a locking ring 602 provided in the socket housing and used for pushing and cooperating with the pressing cylinder 304. Guide sleeves 603 are provided on both sides of the socket housing, and guide pins 202 are provided on both sides of the plug housing and inserted into the guide sleeves for guiding and positioning during the insertion of the plug and the socket. The bottom end of the guide pin has a guiding conical surface for facilitating the insertion and guiding with the guide sleeve. A locking groove 6021 for locking and cooperating with the locking steel ball is provided in the locking ring.

[0035] In this embodiment, a plug contact (not shown in the figure) is further installed in the plug housing, and a socket contact (not shown in the figure) adapted to the plug contact is installed in the socket housing. For example, the plug contact is installed in the first space 203 around the locking assembly, and the socket contact is installed in the second space 604 around the locking ring; the present invention does not limit the shapes and structures of the plug contact and the socket contact.

[0036] Preferably, a sealing ring 411 embedded in the outer wall of the insulating sliding sleeve is provided between the insulating sliding sleeve 402 and the fixed outer sleeve 401 to ensure the sealing performance inside the device. A flange 4023 is further provided on the outer wall of the insulating sliding sleeve 402, and a limiting step 4013 for blocking and cooperating with the flange is provided on the inner wall of the fixed outer sleeve 401, so as to realize the limit of the extreme position of the downward axial sliding of the insulating sliding sleeve.

[0037] Preferably, a plurality of floating springs can be arranged in parallel at intervals in each spring tube; four first floating screws are provided, and the single-side gap L1 between each first floating screw and the corresponding mounting hole on the floating plate is 3 mm, so that the plug housing can float 3 mm in the radial direction relative to the floating plate; after the plug and socket are plugged in, the gap L2 between the head of the second floating screw and the mounting plate is 3 mm, and the gap L3 between the two sides of the floating plate and the bottom of the mounting plate is 3 mm, so that the floating plate can float axially relative to the mounting plate by ±3 mm; it is worth noting that the present invention does not limit the size of the above-mentioned gaps used for floating.

[0038] The working process of the present invention is as follows:

[0039] The plug is fixedly assembled inside the device by means of a mounting plate, and the socket serves as a free end and is driven upward by a mechanical structure or an electric structure to approach the plug and engage with the plug. Figure 3 and Figure 5 The plug is shown unmated from a receptacle. The locking mechanism is unlocked, and the elastic force of spring 404 separates the two shorting pins 403 from their corresponding two sockets 406, creating an insulation barrier between the two sockets. Furthermore, because the present invention utilizes a floating mounting assembly, an axial gap exists between the plug housing and the floating plate. The cover plate and the first floating screws jointly support the plug housing, or the cover plate alone supports the housing through contact with the floating plate. In other words, the plug housing is effectively suspended below the floating plate.

[0040] Combine Figure 9 When the plug and the socket are plugged in, the guide pin and the guide sleeve cooperate to realize radial floating of the plug and automatic alignment of the plug. The radial gap L1 between the first floating screw and the floating plate provides a structural basis for the automatic alignment of the plug, avoiding the interference caused by installation errors and the phenomenon of improper plugging. Then the locking ring of the socket pushes the cylinder. When the locking steel ball 307 enters the locking groove 6021 position of the locking ring, the steel ball is squeezed outward into the locking groove by the core shaft 306 under the elastic reset force of the core shaft spring 305 to achieve locking. In the above locking process, since the locking steel ball no longer blocks the core shaft after entering the locking groove, the core shaft 306 moves downward under the action of the core shaft spring and drives the cover plate 308 to move downward, thereby pressing down the insulating sleeve 402. Then the insulating sleeve 402 drives the short-circuit pin installed inside it to be pressed down. At this time, the locking identification device moves to Figure 9 In the state shown, the locking mechanism is in the locked state, and the two short-circuit pins 403 are respectively plugged into the corresponding two jacks 406 to achieve conduction between the two jacks 406. This conduction signal is led to the corresponding signal receiving system as an identification signal, which can clearly determine that the plug and the socket are fully plugged in and connected.

[0041] During the upward movement of the above socket and the mating process with the plug, since there is an upward thrust on the plug, the plug housing moves upward and abuts against the lower surface of the floating plate. The floating springs on both sides of the floating plate can elastically push against the support cylinder and the mounting plate through the support cylinder, playing a buffering role during mating. After the plug and the socket are fully mated, the state shown in Figure 9 is formed. At this time, the plug housing can achieve radial floating relative to the floating plate, and the plug housing and the floating plate can jointly float up and down axially relative to the mounting plate. When floating upward, the floating springs are further compressed, which ensures that the connector can adapt to working in a high-frequency vibration environment after being locked and can also adapt to installation errors.

[0042] When the plug and the socket need to be separated, the mechanical structure or the electric structure drives the socket to move downward. The socket will also drive the plug to move downward a short distance, but the cover plate and the floating plate first come into contact and are blocked and matched. Under the blocking action of the floating plate, the cover plate pulls the core shaft to move upward relative to the plug housing until the locking steel ball is squeezed into the radial through hole of the core shaft sleeve, and the locking mechanism is unlocked. The plug returns to the Figure 5 state shown. At this time, the restoring force generated by the spring 404 makes the insulating sliding sleeve 402 move upward, and the two short-circuit pins 403 are separated from the corresponding jacks 406, and the two jacks become an open circuit state. The locking mechanism is restored and can be used again. Since the floating plate is used to drive the core shaft to move upward relative to the plug housing during the separation process of the plug and the socket, the entire separation process does not require manual intervention (the existing detachable connector needs to manually pull the core shaft to unlock the locking mechanism), which is suitable for the automated operation of the connector in concealed occasions and can significantly improve the automation level of the whole machine equipment.

[0043] In other embodiments, the locking mechanism can also be installed at the socket end, and the locking identification device is also installed at the socket end. At this time, the locking ring is installed at the plug end; the locking identification device is not limited to being applied in the field of detachable connectors. Its insulating sliding sleeve can be directly or connected to the action or execution components (such as pull rods, core shafts, locking pins, etc.) of the locking mechanism in other types of connectors to achieve synchronous movement, so as to clearly judge the locking state of the connector.

[0044] The above are only the preferred embodiments of the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
