Abstract
The utility model relates to an electrical connecting piece installation tool and especially relates to a torque hand wheel which is used to control a torque force and is used during the electrical connecting piece installation. The torque hand wheel of the utility model is formed by a hand wheel, a mandrel, a ball, a pressure spring and an adjusting screw. The mandrel is arranged in the hand wheel. An outer peripheral surface of the mandrel is uniformly provided with ball positioning pits. The adjacent ball positioning pits are connected through a chute. An inner peripheral surface of the mandrel is provided with a positioning key. The hand wheel is provided with screw thread through holes which are arranged uniformly. Positions of the screw thread through holes correspond to the positions of the ball positioning pits. The ball, the pressure spring and the adjusting screw are arranged in the screw thread through holes. The ball is arranged in the ball positioning pits. The pressure spring is arranged above the ball. The adjusting screw is arranged above the pressure spring. The adjusting screw forms screw thread connection with the screw thread through holes. By using the torque hand wheel of the utility model, a damage to a plug caused by a large twisting force can be effectively avoided. The structure is simple, applicability is strong and usage performance is good.
Description
Technical field
The utility model relates to the instrument that a kind of electrical fitting is installed, and relates in particular to use when a kind of electrical fitting is installed the moment of torsion handwheel of control torsion.
Background technology
Connector also is electrical cnnector, and it is made of joint and socket, is mainly used in the device, transmission current or the signal that connect two active devices.In the prior art, the welding of the end of cable and plug connects housing and overlapped loose wire, and and plug between thread connection usually.But installation personnel is when the assembling of carrying out between plug and the coupling housing, and owing to the use spanner screws it, and the moment of torsion of spanner can't be controlled, and often overexertion damages plug.
Summary of the invention
The purpose of this utility model is in order to solve connector in installation process, owing to overexertion, and produces the problem of infringement.A kind of moment of torsion handwheel is provided, makes setter in installation process, the moment of torsion of spanner rotation is controlled.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of moment of torsion handwheel, constitute by handwheel, mandrel, ball, stage clip and adjustment screw, it is characterized in that: described mandrel is located in the handwheel, the outer circumference surface of mandrel is provided with equally distributed ball positioning pit, link to each other by chute between the adjacent ball positioning pit, the axial location of the interior circle of mandrel is provided with the positioning key that cooperates with connector; Described handwheel is provided with equally distributed tapped through hole, the position of tapped through hole is corresponding with the ball positioning pit, be provided with ball, stage clip and adjustment screw in the tapped through hole, order is: ball places in the ball positioning pit, the ball top is a stage clip, the stage clip top is an adjustment screw, adjustment screw and tapped through hole thread connection.
The number of described ball positioning pit is the twice of tapped through hole number.
Described tapped through hole is three, and the ball positioning pit is six.
The front end of described adjustment screw is provided with plug, and the diameter of plug is less than the internal diameter of stage clip.
Compared with prior art, the locking that the utility model moment of torsion handwheel can be realized plug and coupling housing with separate, have adjustable moment, can effectively avoid twisting the damage that the excessive banjo of power causes.Moment of torsion handwheel of the present utility model is simple in structure, and applicability is strong, and serviceability is good.
Description of drawings
The structural representation that Fig. 1 launches for the moment of torsion handwheel.
Embodiment
Further understand and understanding for making architectural feature of the present utility model and the effect reached had, cooperate detailed explanation, be described as follows in order to preferred embodiment and accompanying drawing:
Referring to Fig. 1, as shown in the figure, a kind of moment of torsion handwheel is made of handwheel 1, mandrel 2, ball 3, stage clip 4 and adjustment screw 5.
Described mandrel 2 is located in the handwheel 1, the outer circumference surface of mandrel 2 is provided with six equally distributed ball positioning pits 21, ball positioning pit 21 is used to place ball 3, its degree of depth is less than half of the diameter of ball, link to each other by chute 22 between the adjacent ball positioning pit 21, ball 3 can roll between adjacent ball positioning pit 21 by chute 22, and the inner peripheral surface of mandrel 2 is provided with positioning key 23, be used for plug on groove chimeric, play position-limiting action.
Described handwheel 1 is provided with three equally distributed tapped through holes 11, the hole of tapped through hole 11 is corresponding with ball positioning pit 21, be provided with ball 3 in the tapped through hole 11, stage clip 4 and adjustment screw 5, ball 3 is placed in the ball positioning pit 21 by tapped through hole 11, stage clip 4 is placed in ball 3 tops, adjustment screw 5 is placed in stage clip 4 tops, adjustment screw 5 and tapped through hole 11 thread connection, the front end of adjustment screw 5 is provided with plug 51, the diameter of plug 51 is less than the internal diameter of stage clip 4, can insert in the stage clip 4, can change its position in tapped through hole 11 by turning adjustment screw 5, thereby change the active force that stage clip 4 acts on ball 3, promptly change the active force that ball 3 acts on ball positioning pit 21.
When using the moment of torsion handwheel, the elastic force of stage clip is regulated in the position that can regulate the adjustment screw in the moment of torsion handwheel, makes the moment of handwheel meet the required moment of product.Carry out spacing with connecting housing with common torque wrench, positioning key on the handwheel mandrel and the groove on the plug is chimeric, make the mandrel of handwheel fixedly be placed on the plug, begin to rotate handwheel, handwheel drives ball and rotates together, ball then drives mandrel and rotates together, rotates thereby make mandrel drive plug, realizes plug and is connected housing locking.When plug rotates required moment greater than the moment of handwheel, the moment that is the plug rotation is greater than the active force of stage clip in the handwheel to ball, when handwheel rotates, handwheel drives ball and rolls between the ball positioning pit of mandrel outside, and send " bang " the machinery sound of colliding, mandrel maintains static, and plug maintains static, thereby has avoided plug and be connected housing and too lock.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in the foregoing description and the specification is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in the claimed scope of the present utility model.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
