Description

Technical Field

[0001] The invention relates to a plug connector device, in particular to a plug connector device capable of automatically separating in an oblique direction and used for precision equipment. Background Art

[0002] Precision equipment is typically packed and transported in storage and transportation boxes. During the packaging and transportation process, electrical testing of the precision equipment is often required without unpacking, allowing for real-time monitoring of its status (e.g., military equipment, aerospace equipment, etc.). Electrical connections must be disconnected before unpacking the precision equipment to ensure safe unpacking. Electrical communication between the storage and transportation box and the precision equipment is achieved via an adapter cable. A plug-in separation mechanism ensures the reliability of the disconnected plug-in of the adapter cable and the socket on the precision equipment. When the precision equipment is unpacked, the disconnected plug-in is separated from the socket by a disconnection signal, disconnecting the electrical signal between the control system and the precision equipment, clearing the way for the precision equipment to be unpacked smoothly.

[0003] The existing plug connector device can realize the separation of the plug connector at the tail position of the precision equipment, ensuring the unlocking reliability and the passability of the precision equipment. However, if the detached plug connector is located at an angle to the precision equipment body, it is difficult to achieve reliable separation of the plug connector and safe removal of the precision equipment from the box.

[0004] Some precision equipment has a unique structural design that prevents connectors from being placed at the rear end. Furthermore, numerous external accessories occupy a significant portion of the internal space, making it impossible to arrange the connectors vertically. Considering both the layout space and the access channel, electrical communication sockets must be placed at an angle. To ensure that any connectors that fall off during the removal of precision equipment from the box are reliably separated, clearing the access channel and preventing collisions between the precision equipment and the connectors, the separation of connectors that can be inserted diagonally is a problem waiting to be solved. Summary of the Invention

DETAILED DESCRIPTION

[0024] like Figure 1 、 4 As shown in Figure 5, the present invention provides a plug connector device for automatically separating obliquely a precision device 04, comprising a plug connector portion 01 and a support portion 02, the plug connector portion 01 comprising a connecting arm 11, a plug connector 12, a telescopic device 13 and a first fixed seat 14, the plug connector 12 being arranged at one end of the connecting arm 11, one end of the telescopic device 13 being connected to the connecting arm 11, and the other end of the telescopic device 13 being connected to the first fixed seat 14; the support portion 02 comprising a support arm 21 and a second fixed seat 22, one end of the support arm 21 being rotatably connected to the other end of the connecting arm 11, and the other end of the support arm 21 being rotatably connected to the second fixed seat 22, the precision device 04 being installed in a storage and transportation box 05, and the first fixed seat 14 and the second fixed seat 22 being fixedly arranged on the inner wall of the storage and transportation box 05.

[0025] The plug connector 12 on the adapter cable is used to connect to the electrical communication interface on the precision device 04, allowing for electrical testing of the precision device 04 without unpacking it, facilitating real-time monitoring of the status of the precision device 04. An electromagnetic lock is installed within the plug connector 12, and a lock with equivalent locking and control functions may also be used. The plug connector 12 is securely secured to the electrical communication interface of the precision device 04 via the lock, with the locking and unlocking of the lock controlled by electrical signals. The plug connector 12 is mounted at the right end of the connecting arm 11, facilitating connection with the precision device 04. The oblique, automatically detachable plug connector device of the present invention is mounted on the lower right or lower left side of the storage and transportation box 05, i.e., between the precision device 04 and the inner wall of the storage and transportation box 05. This allows the plug connector 12 to be separated from the precision device 04, clearing the exit passage and ensuring the safe removal of the precision device 04.

[0026] The telescopic device 13 is the spring 131 described below. The right end of the telescopic device 13 is firmly fixed to the left end of the connecting arm 11, and the left end of the telescopic device 13 is firmly fixed to the first fixing seat 14. The first fixing seat 14 is firmly fixed to the bottom of the storage and transportation box 05, forming a telescopically adjustable plug connector 12 structure. With the help of the telescopic device 13, the plug connector 12 can be telescoped and adjusted in angle, docked with the oblique electrical communication interface of the precision equipment 04, and separated normally when separated.

[0027] The left end of the connecting arm 11 is rotatably connected to the upper end of the support arm 21, and the lower end of the support arm 21 is rotatably connected to the second fixing seat 22. The second fixing seat 22 can be fixed on the bottom of the storage and transportation box 05, or can be set on the side wall of the precision equipment 04 bracket in the storage and transportation box 05. The plug connector 12 device is positioned by the two fixing seats, and the swing range of the connecting arm 11 is limited by the support arm 21 to prevent it from swinging in an unnecessary range.

[0028] When the plug connector 12 is docked with the precision equipment 04, the plug connector 12 device is positioned by the first fixing seat 14 and the second fixing seat 22 to facilitate docking with the precision equipment 04. After positioning, the plug connector 12 and the connecting arm 11 fixed thereto are moved to the upper right, the telescopic device 13 is stretched and extended, and the connecting arm 11 and the support arm 21 and the support arm 21 and the second fixing seat 22 rotate relative to each other. The position of the plug connector 12 is adjusted to dock it with the electrical communication interface on the precision equipment 04, and then the electromagnetic lock in the plug connector 12 is locked. At this time, looking from top to bottom, the connection line of the plug connector 12, the connecting arm 11 and the telescopic device 13 are on the same straight line as the connection between the first fixing seat 14 and the second fixing seat 22, ensuring that the plug connector 12 is not affected by lateral forces when in the plugged state, thereby ensuring the reliability and safety of the connection between the plug connector 12 device and the precision equipment 04.

[0029] When separating, the electromagnetic lock receives the separation electrical signal from the system and is unlocked. The telescopic device 13 retracts to separate the plug connector 12 from the electrical communication interface of the precision equipment 04. The plug connector 12 and the connecting arm 11 gradually move to the lower left. Similarly, during the movement, the connecting arm 11 and the support arm 21 and the support arm 21 and the second fixed seat 22 rotate relative to each other until the plug connector 12 is returned to its position.

[0030] The plug connector 12 device can safely and reliably realize the docking and separation of the electrical communication interface at the oblique position of the precision equipment 04, avoiding friction or collision between the plug connector 12 and the surface of the precision equipment 04. Since the plug connector device is located below the precision equipment 04, it can make way for the precision equipment 04 to be unpacked, ensuring that the precision equipment 04 can be safely and smoothly unpacked from the top of the opening of the storage and transportation box 05.

[0031] like Figure 2 、 3 As shown, the plug connector 12 is arranged on the adapter seat 121, and the adapter seat 121 is located below the plug connector 12. The connecting arm 11 is provided with a limiting groove 112 and a limiting shaft 111 installed in the limiting groove 112; the adapter seat 121 is slidably arranged on the limiting shaft 111.

[0032] Both the adapter 121 and the plug connector 12 are provided with reserved holes. The two are assembled together through the reserved holes and then firmly fixed with screws. The adapter 121 is located below the plug connector 12. The adapter 121 can be replaced with a matching adapter according to the different types of plug connectors 12, meeting the requirements of separating different types of plug connectors 12 from the precision equipment 04 and improving the adaptability of the plug connector 12 device. For example, when replacing the plug connector 12 and the adapter 121, it is only necessary to remove the limit shaft 111 on the connecting arm 11, remove the plug connector 12 and the adapter 121, replace the adapter 121 and plug connector 12 with other types, and then insert the limit shaft 111 into the new adapter 121 and reinstall the limit shaft 111 in the limit slot 112.

[0033] The connecting arm 11 and the supporting arm 21 are both U-shaped structures. Two parallel long limit grooves 112 are provided on the two side walls of the connecting arm 11. There are two limit shafts 111. The adapter 121 is provided with two through holes for being mounted on the limit shafts 111. The adapter 121 is mounted on the two limit shafts 111 and can slide along the length direction of the limit shafts 111. The two limit shafts 111 are respectively installed in the two opposite limit grooves 112 on the connecting arm 11. Sliding the adapter 121 along the limit shaft 111 changes the position of the plug connector 12 on the connecting arm 11, so that the plug connector 12 can be better connected to the precision equipment 04.

[0034] When in use, the plug connector 12 is docked with the precision equipment 04, such as Figure 3As shown, the adapter 121 is slid left and right along the long limit slot 112 to adjust the position of the plug connector 12. At this time, the limit shaft 111 slides left and right in the long limit slot 112, and can fine-tune the stretching distance of the plug connector 12, that is, the plug connector can be adjusted in both the vertical and horizontal directions to ensure that the plug connector 12 better fits the angle of the oblique electrical communication interface of the precision equipment 04, and enhances the stability of the plug connector 12 in connecting and separating with the electrical communication interface of the precision equipment 04 at different angles. With this arrangement, the plug connector 12 has a short recovery time, a large adaptability angle for connection, and a wide adjustable range.

[0035] like Figure 1 、 2 As shown, the support arm 21 is provided with two spaced apart limiting rods 211, and the connecting arm 11 passes between the two limiting rods 211 and is rotatably connected to the support arm 21. The connecting arm 11 and the support arm 21 are rotatably connected via a first locking pin; the support arm 21 and the second fixing base 22 are rotatably connected via a second locking pin.

[0036] Two limit rods 211 are provided on the right side of the upper end of the support arm 21 along the up and down directions. The distance between the limit rods 211 is greater than the width of the left end of the connecting arm 11. The left end of the connecting arm 11 passes through the two limit rods 211 and is rotatably connected to the left side of the support arm 21 through the first locking pin. Thus, the relative rotation range between the connecting arm 11 and the support arm 21 is limited by the two limit rods 211.

[0037] Multiple limit rods 211 can be provided along the length of support arm 21, and they are detachably mounted. By adjusting the position of limit rods 211, specific restrictions can be imposed on electrical communication interfaces at different locations on precision device 04, improving insertion accuracy. For example, when docking with an electrical communication interface at the rear of precision device 04, limit rods 211 can be adjusted to allow a wider range of rotation for connecting arm 11; whereas, when docking with an electrical communication interface on the side of precision device 04, the rotation range can be appropriately reduced.

[0038] The connecting arm 11 and the support arm 21 as well as the support arm 21 and the second fixed seat 22 are all rotationally connected by a locking pin. Of course, other rotational connection methods can also be used, such as a universal joint. The pin-type rotational connection is convenient for limiting the rotational direction of related components through components such as the limit rod 211; on the other hand, the pin-type connection structure is relatively simple, and the component cost and installation cost are low, which is conducive to cost savings.

[0039] like Figure 1 As shown, the telescopic device 13 is a spring 131 , one end of the spring 131 is connected to the first lock pin, and the other end of the spring 131 is connected to the first fixing seat 14 .

[0040] Retractable device 13 utilizes a highly durable and strong spring 131. This spring 131 maintains a stable elastic coefficient within a reasonable range over long-term use, ensuring stable operation of plug connector 12. This stable elastic coefficient ensures that spring 131 provides consistent force each time it retracts and retracts, making the connection and disconnection of plug connector 12 more precise and reliable. Furthermore, springs 131 with different coefficients can be replaced for different precision equipment, enhancing the adaptability of plug connector 12.

[0041] The connecting arm 11 and the supporting arm 21 are both made of metal material through machining. The metal material itself has a certain toughness and rigidity, ensuring that it can be used for a long time without bending, breaking or other failures, thereby extending the service life.

[0042] The right end of the spring 131 is firmly sleeved on the first locking pin, and the left end is sleeved on the locking pin on the first fixing seat 14. During operation, when the plug connector 12 is plugged into the electrical communication interface of the precision equipment 04, the electromagnetic lock is locked, and the spring 131 is in a stretched state at this time; when separated, the electromagnetic lock is opened, and the stretched spring 131 provides an initial force for the separation of the plug connector 12 (i.e., the elastic force of the spring 131), ensuring that the plug connector 12 is normally separated from the precision equipment 04 under the action of the elastic force of the spring 131 and its own gravity. During the separation process, the plug connector 12 and the connecting arm 11 are always supported by the support arm 21 during the retreat process, avoiding friction between the plug connector 12 and the surface of the precision equipment 04, further improving the stability and safety of the plug connector 12 device.

[0043] like Figure 3 As shown, the support arm 21 is also provided with at least two cable limiting pins 212 arranged at intervals from each other along the length direction. Each cable limiting pin 212 is connected to two opposite side walls of the U-shaped support arm 21. Two adjacent cable limiting pins 212 cooperate with the two side walls of the U-shaped support arm 21 to form a cable channel.

[0044] The cable channel is used for routing cables, and the cable channel can better restrain the cables to ensure that the cables do not rub against other components and the surface of precision equipment 04, thereby improving the safety of the plug connector 12 device and extending its service life.

[0045] like Figure 1 、 4 As shown, the device further includes a buffer support seat 03, which is disposed between the first fixing seat 14 and the second fixing seat 22. When the plug connector 12 is separated from the electrical communication interface of the precision device 04, under the tension of the spring 131, the support arm 21 rotates around the second locking pin and can abut against the buffer support seat 03. At this time, the support arm 21 is supported on the buffer support seat 03.

[0046] After the plug connector 12 device is positioned by the first fixing seat 14 and the second fixing seat 22, the position of the support arm 21 is also determined. In the initial state, the support arm 21 is supported on the buffer support seat 03 fixed between the first fixing seat 14 and the second fixing seat 22.

[0047] In the plugged state, the support arm 21 is away from the buffer support seat 03. In the separated state, the electromagnetic lock is opened, and the plug connector 12 is separated from the precision device 04 under the elastic force of the spring 131. The plug connector 12 and the connecting arm 11 move rapidly away from the precision device 04. Driven by the connecting arm 11, the support arm 21 rotates counterclockwise around the second fixed seat 22 until it collides with the buffer support seat 03. After being buffered by the buffer support seat 03, the support arm 21 is stably supported on the buffer support seat 03.

[0048] The buffer support seat 03 is made of a material with good buffering properties (such as rubber), and its structure can effectively absorb and disperse impact force, preventing the support arm 21 from colliding with the buffer support seat 03 and causing deformation and other failures, ensuring the safety of the separation process, and thus extending the service life of the plug connector 12 device.
