Description

Connecting device of cable joints

Technical field

The present invention relates to a kind of connecting device of cable joints, be used for the connection between two cable joints.

Background technology

The pure electric automobile multi-function test stand is the device that a cover is specifically designed to the motor in electric automobile Performance Detection, when detecting test, power cord connector and laboratory's electrical source of power wire terminal of motor need to be linked together.Because the motor power-supply wire joint form that motor is equipped with on the market is varied, and laboratory's power power-line only has been equipped with a kind of joint.Therefore, in order to test different motors, needing to spend the plenty of time before the test carries out joint replacing, and the electrical source of power wire terminal is difficult to dismounting, line can only be cut off, and reinstalls new joint, not only complex operation is wasted time and energy, and has greatly reduced the efficient of test.Along with the continuous replacing of electrical source of power wire terminal, the length of power power-line can constantly shorten, and when the contraction in length of power power-line is extremely not enough, must change whole power power-line, has caused like this waste of line and joint, has increased the cost of test.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of connecting device of cable joints, in order to fast two cable joints are linked together.

Technical scheme of the present invention is as follows: a kind of connecting device of cable joints, comprise housing, insulation board, spring and depression bar, and its middle shell is the hollow structure of open at both ends, is provided with insulation board in housing, this insulation board is connected with the interior diapire of housing by spring; Top at described housing has window, be provided with depression bar in this window, described depression bar is comprised of cam and handle, wherein handle is positioned at outside the window, and link to each other with the basic circle of cam, described cam is made by insulating material, and the center of this cam is connected with housing by axle, and described depression bar can rotate relative to housing.

Although the form of motor power wire terminal is varied, but can find in actual use, in order to guarantee that the motor power wire terminal has enough large contact area, the motor power wire terminal has one side to be the plane when design, utilize this characteristics, the present invention can link together motor power wire terminal and electrical source of power wire terminal.When connecting, first with uncovered the stretching into of electrical source of power wire terminal from housing one end, and lie on the insulation board, then the motor power wire terminal is stretched into from the uncovered of the housing other end, making the motor power wire terminal is that the one side on plane is fitted with the electrical source of power wire terminal, then use the handle of hand down-pressed pole, depression bar is rotated relative to housing, until the flange of cam towards lower compression in the motor power wire terminal, this moment, spring was in compressive state, and upwards applying elastic force, spring force passes through insulation board, electrical source of power wire terminal and motor power wire terminal pass to cam, and the elastic force center by cam basically, so that cam forms self-locking, in the situation that there is not other external force, depression bar is in the lock state, and can not become flexible; Simultaneously, the cam of depression bar and spring combination, wire terminal remains good contacting with motor power can to make the electrical source of power wire terminal.In the time of dismounting, only need with hand counter-rotation depression bar, the compressing that depression bar is unclamped the motor power wire terminal gets final product.Insulation board and cam are all non-conductive, and the security performance that connects two joints accesses guarantee.

Be connected by four springs by the rectangular distribution between the interior diapire of described insulation board and housing, insulation board is stressed during spring-compressed so evenly can not be offset, and has guaranteed that two joints connect firm.

The cam of described depression bar and handle are the integrative-structure of injection mo(u)lding, and processing and fabricating is easy, and production cost is low; The flange of described cam and the angle between the handle are the obtuse angle, handle like this depression bar and rotate more convenient, laborsaving.

The end face of described cam flange is the plane, and cam is fitted by plane and motor power wire terminal when the depression bar self-locking like this, and is more reliable to the depression bar lock-bit on the one hand; On the other hand, can further guarantee the motor power wire terminal fixing that wire terminal is connected with electrical source of power.

For the ease of processing, reduction cost, and improve housing for the structural strength of axle installation position, and being provided with journal stirrup in the bilateral symmetry of described case top window, this journal stirrup and housing are connected as a single entity, and by injection mo(u)lding, the two ends of described axle are located in respectively in two journal stirrups.

Beneficial effect: the present invention can link together motor power wire terminal and electrical source of power wire terminal quickly and easily, not only can guarantee that two joints connect firm, and processing ease, dismounting are convenient, time saving and energy saving, greatly improved test efficiency, avoid power line and joint to damage, saved experimentation cost.Simultaneously, the cable connector that the present invention can also be used for other type connects, and the scope of application is very extensive.
