Background
The spacecraft connection and separation technology is a key technology for implementing the compression and on-orbit release of spacecraft components, the connection and on-orbit separation between cabin segments and the on-orbit connection and separation between different spacecraft. The connection and separation mechanism is an execution device for realizing connection and separation/functions of the spacecraft. With the continuous extension of the task of on-orbit connection and disconnection of a spacecraft, the function of the connection and disconnection mechanism is not limited to mechanical connection and disconnection, and generally comprises connection and disconnection of an electric circuit and an information circuit. The electric connector is a device which is arranged on the connection and separation mechanism and used for switching on and off a circuit and an information path.
The connection and separation mechanism is generally composed of two parts, namely a driving end 1 and a driven end 2, which are respectively arranged on two spacecraft or part components, and after the driving end 1 is connected with the driven end 2, the two spacecraft or the two part components are connected; and separating the materials and vice versa.
The electric connector is generally composed of a plug 3 and a socket 4, and is respectively arranged on the driving end 1 and the driven end 2 as shown in fig. 1, and after the driving end 1 and the driven end 2 are connected, the plug 3 and the socket 4 of the electric connector are connected; and separating the materials and vice versa.
The connection and disconnection process of the electric connector is synchronous with the butt joint and disconnection process of the driving end 1 and the driven end 2, the driving end 1 and the driven end 2 provide power sources for the connection and disconnection of the plug 3 and the socket 4, and meanwhile, the connection and disconnection mechanism formed by the driving end 1 and the driven end 2 provides tolerance guarantee for the plug 3 and the socket 4 to be plugged. An important design aspect of the connection and disconnection device in the design process is the tolerance design of the end-face plug-in electrical connector.
By electrical connector tolerance design is meant the ability to ensure the relative attitude of the plug 3 and the receptacle 4 during mating of the active end 1 and the passive end 2 of the disconnect mechanism. The posture here includes the positions and angles α, β, γ of the X, Y, Z three directions. The positional accuracy required for plugging a typical electrical connector plug 3 with a receptacle 4 is shown in table 1, and the X direction is the plugging direction.
Table 1 electrical connector plugging position accuracy requirements
| Direction | ΔY | ΔZ | Δα | Δβ | Δγ |
| Deviation of | 1.27mm | 2.03mm | ±0.5° | ±0.5° | ±0.5° |
Deviations in directions of Δy and Δz Y, Z, respectively, and deviations of angles α, β, and γ are respectively denoted by Δα, Δβ, and Δγ; in summary, the tolerance index of the connection and disconnection mechanism needs to be smaller than the precision of the plugging position in table 1 to ensure reliable plugging of the plug 3 and the socket 4.

Detailed Description
The invention is described in further detail below with reference to the accompanying drawings.
The invention relates to a tolerance design method of an end face inserting connection separation mechanism of an electric connector, which adopts a coarse correction and deviation correction two-stage mode, and specifically comprises the following steps:
the rough correction and deviation rectification is realized by circumferentially designing the claws 101 at the driving end 1 to be matched with the clamping grooves 201 designed on the driven section. The clamping groove 201 is designed at the equidistant positions of the passive end 2 in the circumferential direction, the clamping groove 201 is axially arranged along the passive end 2, and an abutting plate is designed at the end part of the clamping groove 201.
The claws 101 are arranged at intervals of Xiang Dengjiao degrees along the periphery of the driving end 1, and the claws 101 are driven to be unfolded and folded through the driving mechanism inside the driving end 1. The grabbing end 102 of the paw 101 is designed to be of a plate-shaped structure which is bent inwards by 90 degrees, the shape and the size are matched with the cross section of the clamping groove 201, and therefore the grabbing end 102 of the paw 101 is matched and inserted into the clamping groove 201 to realize coarse correction by controlling the paw 101 to extend and then retract. By adopting the claw 101 and the clamping groove 201 with the shapes, the claw 101 can conveniently reach the clamping groove 201 during butt joint, and the adaptability is good. When the hand claw 101 reaches the position of the clamping groove 201, the hand claw 101 is guided by the two side surfaces of the clamping groove 201 to extend into the clamping groove 201 continuously, namely, the postures of the driving end 1 and the driven end 2 are corrected continuously, and the rough correction and deviation correction between the driving end 1 and the driven end 2 are completed. The mounting mode of the paw 101 is a cantilever beam, so that proper torsion can be generated in the course of rough correction and deviation correction, the requirement on the machining and assembling precision of the system is low, and the flexible design of the system is realized.
The fine correction is realized by the insertion fit of a guide rod 103 designed on the abutting surface of the driving end 1 and a guide rod hole 202 designed at a corresponding position on the abutting surface of the driven end 2. After the rough correction and deviation correction in the first stage are completed, the guide rod 103 and the corresponding guide rod hole 202 are matched into position, and then the fine correction and deviation correction in the second stage are completed. After the two-stage correction is completed, the tolerance between the active end 1 and the passive end 2 is smaller than the tolerance between the electric connector plug 3 and the socket 4, so that the electric connector plug 3 and the socket 4 can be ensured to be inserted without faults.
The front end of the guide rod 103 is chamfered, and the front end of the guide rod hole 202 is chamfered as well. Let the outer diameter of the guide rod 103 be d and the chamfer be C d If the diameter of the guide rod hole 202 is D, the chamfer C is formed D The requirements are as follows:
D+2C D -d-2C d ≥Δ
wherein delta is the comprehensive tolerance of the driving end 1 and the driven end 2 after rough correction and deviation correction, and the value needs to consider the position deviation in three directions and the angle deviation in three directions.
When the method of the invention is adopted for correcting deviation, the method is as shown in fig. 4:
before the connector is inserted, the initial deviation between the active end 1 and the passive end 2 is as follows: Δy=50 mm, Δz=50 mm, Δα= ±0.5°, Δβ= ±0.5°, Δγ= ±0.5°; the initial capture correction is realized by matching the three claws 101 with the clamping groove 201, the front ends of the three claws 101 approach the clamping groove 201 in the initial capture process, and the structure of the claws 101 and the clamping groove 201 is matched for correction, namely the rough correction is finished. The lower end face of the roughly corrected paw is attached to the lower end face of the clamping groove 201, and all the three-direction angular deviations of the driving end 1 and the driven end 2 are corrected to be 0 degrees. The deviation of the driving end 1 and the driven end 2 along the two directions of deltay and deltaz and the structural dimensions of the paw 101 and the clamping groove 201 are determined, according to the conventional machining precision, the dimensional deviation can be controlled to be less than 2mm, the paw 101 is allowed to deform greatly after coarse capturing, but the maximum deformation is not more than 1mm, and the deltay=2 mm, deltaz=2 mm, deltaa=0, deltabeta=0 and deltay=0 are comprehensively considered after coarse correcting and rectifying are completed.
In the stage of fine correction, D+2C needs to be satisfied D -d-2C d Not less than DeltaY and D+2C D -d-2C d And (2) not less than deltaZ, namely, before the guide rod 103 of the driving end 1 starts to be positioned in the guide rod hole 202 on the driven end 2, the initial tolerance of the fine correction and deviation correction is required to be superior to the tolerance deltaY and deltaZ of the final stage of the coarse correction and deviation correction. The clearance between the guide rod 103 and the guide rod hole 202 is D+2C after the guide rod 103 is completely positioned D -d-2C d The gap is a result of considering the machining deviation and the position deviation, and can meet the deviation of the Y direction and the Z direction of the electric connector, and the fine correction and deviation correction are completed. Final tolerance requirementsThe tolerance of the electric connector is smaller than that of the electric connector, the precision requirement of the plugging position is met, and the reliable plugging of the plug 3 and the socket 4 is ensured.
