Description

Technical Field

[0001] This invention relates to a release device and method for a rope-controlled ball-locking electrical connector, belonging to the field of spacecraft payload connection and separation technology. Background Technology

[0002] Electrical connectors enable the transmission of electrical energy and signals between spacecraft and their internal payloads. In special circumstances, reliable separation of interconnected electrical connectors is required. With the rapid development of electrical connector technology, standardized electrical connectors capable of reliable separation via their own mechanisms are now available, and there are successful application cases in spacecraft. However, for detachable spacecraft payloads, the reliable separation of connected electrical connectors is a critical factor affecting mission success. Some models of electrical connectors have electrically unlocking and release functions, but situations may arise where the electrical unlocking fails to trigger or separation is incomplete, leading to connector release failure. Therefore, during the use of electrical connectors, a forced release device needs to be designed and installed to ensure that the connectors can effectively perform the separation task during the unlocking and separation process.

[0003] Therefore, there is an urgent need to propose a reusable rope-controlled ball-locking electrical connector release device and method to solve the above-mentioned technical problems. Summary of the Invention

[0004] This invention addresses the problem of connector unlocking failure due to incomplete or non-triggered electrical unlocking, providing a reusable cord-controlled ball-lock type electrical connector release device and method. A brief overview of the invention is given below to provide a basic understanding of certain aspects thereof. It should be understood that this overview is not an exhaustive summary of the invention. It is not intended to identify key or essential parts of the invention, nor is it intended to limit the scope of the invention.

[0005] The technical solution of the present invention:

[0006] A reusable rope-controlled ball-locking electrical connector release device includes a clamping plate, a pressure plate, a locking wire rope, an inner sleeve, an outer sleeve, a tension spring, and a steel ball. The upper end of the inner sleeve is provided with a clamping plate, and the inner sleeve is slidably disposed inside the outer sleeve. A tension spring is provided between the inner sleeve and the outer sleeve. A steel ball is disposed in the mounting hole of the outer sleeve. The outer side of the outer sleeve is rotatably connected to the upper end of the pressure plate. The pressure plate and the steel ball are correspondingly arranged, and the lower end of the pressure plate is connected to the locking wire rope.

[0007] Preferably, the electrical connector socket is fixedly installed on the load that requires power, the electrical connector plug is inserted into the electrical connector socket, the side of the electrical connector plug has a boss, and the boss of the electrical connector plug is located inside the inner sleeve.

[0008] Preferably, it also includes screws, and the clamping plate is detachably connected to the inner sleeve by the screws. The outer side of the inner sleeve is machined with a groove corresponding to the steel ball.

[0009] Preferably, the upper end of the inner sleeve has three circumferentially equidistant mounting platforms, and a groove structure is formed between adjacent mounting platforms. Each mounting platform is provided with an arc-shaped clamping plate. The inner diameter of the circle formed by the circumferentially arranged clamping plates is smaller than the outer diameter of the electrical connector plug boss, and the inner diameter of the inner sleeve is larger than the outer diameter of the electrical connector plug boss.

[0010] Preferably, the device also includes a rotating shaft, and the number of pressure plates is two, which are symmetrically arranged. The upper end of the pressure plates is connected to the outer sleeve through the rotating shaft.

[0011] Preferably, there are two tension springs, which are symmetrically arranged and located inside the outer sleeve. The two ends of the tension springs are fixedly connected to the lower part of the inner sleeve and the lower part of the outer sleeve, respectively.

[0012] Preferably, it also includes a guide shaft and a guide ring. The outer sleeve has four equidistant openings, two of which are symmetrical side openings corresponding to the tension springs, and the guide shaft is located in the middle of the other two symmetrical openings. A guide ring is fixedly installed on the lower outer side of the outer sleeve, and the guide ring is corresponding to the guide shaft. The locking wire rope passes through the guide ring, the lower opening of the guide shaft, and the upper opening of the guide shaft in sequence and is fixedly connected to the pressure plate.

[0013] Preferably, it also includes a mounting base, which is detachably disposed at the lower part of the outer sleeve.

[0014] Preferably, the outer wall of the outer sleeve is provided with a stop, and the upper end of the pressure plate is machined with a bevel structure, which fits with the lower end face of the stop.

[0015] A method for releasing a reusable cord-controlled ball-locking electrical connector includes the following steps:

[0016] Step 1: Before the electrical connector release device is activated, the electrical connector socket is fixedly installed on the load that needs power. The electrical connector plug is inserted into the electrical connector socket. There is a certain insertion and extraction force between the electrical connector socket and the electrical connector plug to ensure that the electrical connector plug does not fall off.

[0017] Step 2: Secure the mounting base to the fixed load that does not require separation, keeping the mounting base and the electrical connector socket relatively stationary; apply locking force to the locking wire rope, press the steel ball with the pressure plate, so that the steel ball enters the groove on the outer side of the inner sleeve, positioning the inner sleeve, with the tension spring in a stretched state, place the electrical connector plug boss in the inner sleeve, and rotate the screw to connect the retaining plate to the inner sleeve;

[0018] Step 3: When the electrical connector is unlocked, the locking force on the locking wire rope disappears, the pressure plate no longer provides locking pressure to the locking steel ball, and the inner sleeve moves downward under the tension of the tension spring, squeezing the locking steel ball out of the groove.

[0019] Step 4: The clamp is engaged with the protrusion of the electrical connector plug, and the electrical connector plug is pulled out of the electrical connector socket under the action of tension. When the electrical connector plug and the electrical connector socket are completely separated, the forced disconnection of the electrical connector is completed.

[0020] The present invention has the following beneficial effects:

[0021] 1. When the electrical connector of the present invention is unlocked, the impact generated by the forced release device is small, which can effectively reduce the unlocking impact on the spacecraft payload during the unlocking process;

[0022] 2. This invention uses steel ball locking, which can generate a large locking force and can quickly unlock and disengage during unlocking;

[0023] 3. The pressure plate of the present invention has a mechanical limit, which limits the steel ball by the unfolding angle to ensure that it will not detach from it, and no extra material is generated in the release device before and after unlocking;

[0024] 4. The present invention has a simple structure, ensures complete electrical separation of the electrical connector, has high reliability, and can be used multiple times. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0037] Specific implementation method one: Combining Figure 1This embodiment describes a reusable rope-controlled ball-lock type electrical connector release device, comprising a clamping plate 1, a pressure plate 3, a locking steel wire rope 5, an inner sleeve 10, an outer sleeve 11, a tension spring 12, and a steel ball 14. The upper end of the inner sleeve 10 is provided with the clamping plate 1, and the lower part of the inner sleeve 10 is slidably disposed inside the outer sleeve 11. A tension spring 12 is provided between the inner sleeve 10 and the outer sleeve 11. A steel ball 14 is disposed in the mounting hole of the outer sleeve 11. The outer surface of the outer sleeve 11 is rotatably connected to the upper end of the pressure plate 3. The pressure plate 3 and the steel ball 14 are correspondingly arranged. The lower end of the pressure plate 3 is connected to the locking steel wire rope 5. The steel wire rope used in this invention has flexible characteristics, enabling remote control via the steel wire rope. During use, the electrical connector socket 7 is fixedly installed in the load requiring power, and can be adjusted as needed. The load is separated during the separation process. Before use and during power supply, the electrical connector plug 8 is inserted into the electrical connector socket 7. The inner sleeve 10 and the unlocking plate 1 clamp the electrical connector plug 8. During separation, the protrusion of the electrical connector plug 8 bears the unlocking and pulling force. The rope-controlled unlocking electrical connector release device is installed on the fixed load that does not need to be separated. Before the action, the locking wire rope 5 is in a taut state, and the electrical connector release device does not act. When the electrical connector needs to be forcibly released, the tension on the locking wire rope 5 disappears, the electrical connector release device is triggered, and the inner sleeve 10 and the unlocking plate 1 pull the electrical connector plug 8 out of the electrical connector socket 7, completing the forced release of the electrical connector. The present invention has a simple structure, ensures complete electrical separation of the electrical connector, has high reliability, and can be used multiple times.

[0038] Specific Implementation Method Two: Combining Figure 1-9 This embodiment describes a reusable rope-controlled ball-lock type electrical connector release device. The electrical connector socket 7 is fixedly installed on the load that needs power. The electrical connector plug 8 is inserted into the electrical connector socket 7. The side of the electrical connector plug 8 has a boss, and the boss of the electrical connector plug 8 is located inside the inner sleeve 10.

[0039] Specific implementation method three: Combining Figure 1-9 This embodiment describes a reusable rope-controlled ball-locking electrical connector release device, which also includes a screw 9. The locking plate 1 is detachably connected to the inner sleeve 10 via the screw 9. The outer side of the inner sleeve 10 is machined with a groove corresponding to the steel ball 14 to further improve stability.

[0040] Specific implementation method four: Combination Figure 1 , Figure 7This embodiment describes a reusable rope-controlled ball-lock type electrical connector release device. The upper end of the inner sleeve 10 has three circumferentially equidistant mounting platforms, forming a groove structure between adjacent platforms. Each mounting platform is equipped with an arc-shaped retaining plate 1. The inner diameter of the circle formed by the circumferentially arranged retaining plates 1 is smaller than the outer diameter of the protrusion of the electrical connector plug 8, while the inner diameter of the inner sleeve 10 is larger than the outer diameter of the protrusion of the electrical connector plug 8. The split-design arc-shaped retaining plate 1 is not limited by the shape of the connecting wire or the electrical connector socket 7, facilitating installation and allowing selection based on the plug model, thus offering good adaptability. When the protrusion of the electrical connector plug 8 is annular, it can be placed inside the inner sleeve 10 before installing the retaining plate 1. When the protrusion of the electrical connector plug 8 is a discontinuous arc structure, it can be inserted into the groove structure and then rotated to position the protrusion under the retaining plate 1. Installation can be completed without disassembling the retaining plate 1, reducing weight. The groove structure also provides space for other components connected to the plug, serving a clearance function.

[0041] Specific Implementation Method Five: Combining Figure 1-10 This embodiment describes a reusable rope-controlled steel ball lock type electrical connector release device, which also includes a rotating shaft 2. The number of pressure plates 3 is two, and the number of pressure plates 3 is the same as that of steel balls 14. The pressure plates 3 are symmetrically arranged, and the upper end of the pressure plates 3 is connected to the outer sleeve 11 through the rotating shaft 2.

[0042] Specific Implementation Method Six: Combination Figure 1-8 This embodiment describes a reusable rope-controlled ball-lock type electrical connector release device. It includes two tension springs 12, symmetrically arranged inside the outer sleeve 11. The two ends of each tension spring 12 are fixedly connected to the lower part of the inner sleeve 10 and the lower part of the outer sleeve 11, respectively. This ensures uniform force distribution, achieving not only axial tension but also automatic adjustment of the circumferential position of the inner sleeve 10.

[0043] Specific implementation method seven: Combining Figure 1-8This embodiment describes a reusable rope-controlled ball-locking electrical connector release device, which includes a guide shaft 4 and a guide ring 6. The outer sleeve 11 has four equidistant openings, two of which are symmetrically positioned to correspond to the tension spring 12. The edges of these openings are designed with graduations, allowing observation of the tension spring's tilt and the bottom position of the inner sleeve 10 to determine the groove position, facilitating proper installation during assembly. This design not only simplifies the structure and reduces weight but also improves installation efficiency. The guide shaft 4 is positioned in the center of the other two symmetrical openings. A guide ring 6 is fixedly positioned on the lower outer side of the outer sleeve 11, corresponding to the guide shaft 4. A locking wire rope 5 sequentially passes through the guide ring 6, the lower opening of the guide shaft 4, and the upper opening of the guide shaft 4, and is fixedly connected to the pressure plate 3. This causes the locking wire rope 5 to pull the pressure plate 3 towards the outer sleeve 11, ensuring reasonable force distribution and preventing scratches that could affect the wire rope's condition.

[0044] Specific implementation method eight: Combination Figure 1-9 This embodiment describes a reusable rope-controlled ball-locking electrical connector release device, which also includes a mounting base 13. The mounting base 13 is detachably disposed at the lower part of the outer sleeve 11. The mounting base can be selected according to the actual site conditions without changing other structures, making it highly adaptable. This invention has the advantages of simple structure, high reliability, and multiple uses on the ground. It is not only low in manufacturing cost but also low in cost during use and maintenance.

[0045] Specific Implementation Method Nine: Combining Figure 1-10 This embodiment describes a reusable rope-controlled ball-locking electrical connector release method. A stop 16 is provided on the outer wall of the outer sleeve 11. An inclined structure 15 is machined on the upper end of the pressure plate 3, and the inclined structure 15 engages with the lower end face of the stop 16 to limit the rotation angle of the pressure plate 3. The angle between the inclined structure 15 and the plate surface 17 of the pressure plate 3 that engages with the steel ball is β. The maximum rotation angle of the pressure plate 3 is θ. Since the bottom of the stop 16 is perpendicular to the outer surface of the outer sleeve 11, β + θ = 90°. The distance from the bottom edge of the mounting hole to the axis of rotation 2 is l, and the radius of the steel ball 14 is R. To prevent the ball from falling off, the following conditions must be met: but The distance between the center of rotation of the steel ball center locking pressure plate and the center of rotation is 6.7mm, the diameter of the steel ball is 4mm, the maximum angle of rotation of the locking pressure plate is 33.12°, and the minimum included angle between the inclined structure 15 and the pressure plate 3 should be designed to be 56.48°. This parameter is the optimal solution, which generates a large locking force and can quickly unlock and disengage when unlocking. Since the locking pressure plate has a mechanical limit at the position of the rotation axis, it can only rotate at a fixed angle. The locking steel ball will not come out from the gap of the locking pressure plate during rotation. Combined with the blocking effect of the outer side of the inner sleeve, no extra material will be generated.

[0046] Specific Implementation Method Ten: Combining Figure 1-10 This embodiment describes a method for releasing a reusable rope-controlled ball-locking electrical connector, which employs a reusable rope-controlled ball-locking electrical connector release device and includes the following steps:

[0047] Step 1: Before the electrical connector release device is activated, the electrical connector socket 7 is fixedly installed on the load that needs power. The electrical connector plug 8 is inserted into the electrical connector socket 7. There is a certain insertion and extraction force between the electrical connector socket 7 and the electrical connector plug 8 to ensure that the electrical connector plug 8 does not fall off. When separating, a certain release force is required to overcome the insertion and extraction force in order to separate the electrical connector plug.

[0048] Step Two: Fix the mounting base 13 onto the fixed load that does not require separation, keeping the mounting base 13 and the electrical connector socket 7 relatively stationary. Through a reasonable design, the outer sleeve is fixedly installed on the mounting base, and both the wire ring and the wire shaft are installed on the outer sleeve. The wire rope passes through the wire ring, wraps around the wire shaft, and connects to the locking pressure plate. The locking pressure plate is connected to the outer sleeve via a rotating shaft. The inner sleeve and the outer sleeve have a clearance fit, allowing for relative sliding. A locking steel ball is installed between the inner sleeve and the outer sleeve 11, and the steel ball is installed in the mounting hole of the outer sleeve. A locking force (downward tension) is applied to the locking steel wire rope 5. The lower end of the locking steel wire rope 5 can be connected to a linear motor for force adjustment. The lower end of the locking steel wire rope 5 can also be connected to the YF17-36 type circular detachable electrical connector. The connection is achieved by pressing the steel ball 14 under the tension of the locking wire rope through the pressure plate 3, so that the steel ball 14 enters the groove on the outer side of the inner sleeve 10, positioning the inner sleeve 10. That is, in the locked state, the locking steel ball is embedded in the groove of the inner sleeve under the pressure of the locking pressure plate, so that the inner sleeve and the outer sleeve cannot slide relative to each other. An unlocking tension spring is installed between the inner sleeve and the mounting base. The tension spring 12 is in a stretched state, so that the inner sleeve always maintains a downward tension. Rotating the screw separates the clamping plate from the inner sleeve, and the protrusion of the electrical connector plug 8 is placed in the inner sleeve 10. Rotating the screw 9 in the opposite direction connects the clamping plate 1 to the inner sleeve 10. There is a clearance fit between the inner sleeve 10, the clamping plate 1 and the electrical connector plug 8. Before unlocking or disengaging, the electrical connector plug 8 is not subjected to the force of the unlocking clamping plate 1 and the inner sleeve 10.

[0049] Step 3: When the electrical connector is unlocked, the locking force on the locking wire rope 5 disappears, the pressure plate 3 no longer provides locking pressure to the locking steel ball 14, and the steel ball 14 can move in the air in the outer sleeve 11 after losing the pressure of the locking pressure plate 3; the inner sleeve 10 moves downward under the action of the tension spring 12 and squeezes the locking steel ball 14 out of the groove.

[0050] Step 4: During the downward movement of the inner sleeve 10, the unlocking plate 1 moves downward together. The plate 1 locks onto the protrusion of the electrical connector plug 8. The electrical connector plug 8 is pulled out of the electrical connector socket 7 by the pulling force of the unlocking spring. When the electrical connector plug 8 is completely separated from the electrical connector socket 7, the forced release of the electrical connector is completed, and the spring plays a shock-absorbing role. When the electrical connector of the present invention is unlocked, the impact generated by the forced release device is less than 400g, which not only protects the device and plug and improves its reusability, but also effectively reduces the unlocking impact on the spacecraft payload during the unlocking process.

[0051] It should be noted that in the above embodiments, as long as the technical solutions are not contradictory, they can be permuted and combined. Those skilled in the art can exhaust all possibilities based on the mathematical knowledge of permutation and combination. Therefore, the present invention will not describe the technical solutions after permutation and combination one by one, but it should be understood that the technical solutions after permutation and combination have been disclosed by the present invention.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
