Embodiment:
See shown in accompanying drawing 1 ~ 11, a kind of cable connection structure with auto-lock function, comprising: electrode connecting end 1 or test extension lead plug end 3 and self-locking test cable 2.Described self-locking test cable 2 comprises again: self-locking connector 20, wire 21 and cable plug end 22.Described self-locking connector 20 comprises again: connector inner casing 201, connection reed 202, the quiet shell 203 of connector and connector move shell 204.
In present embodiment, as shown in Figure 5, be fitted into the relevant position of connector inner casing 201 after four connection reeds 202 weld with wire 21, connector inner casing 201 is divided into left and right two parts so that assembling.Wire outlet position on described connector inner casing 201 is equipped with muscle position feature 2011, can clamping wire 21, makes the outside stress point pulling wire act on this position and is unlikely to destroy the solder joint connecting reed 202 and wire 21.
As can be seen from figures 6 to 8, the quiet shell 203 of described connector is by the notch feature 2012 of muscle position feature 2031 matching connector inner casing 201, limit therebetween around the relative motion of axial-rotation, the quiet shell 203 of described connector, by the snap features 2013 of circular hole feature 2032 matching connector inner casing 201, limits axial relative motion therebetween.Described connector moves the notch feature 2014 of shell 204 by muscle position feature 2041 matching connector inner casing 201, therebetween can around axial-rotation 90 degree, described connector moves three notch feature 2015 of shell 204 by tibet cinnamon bark position feature 2043 matching connector inner casing 201, realize the locking of axial motion therebetween, in addition therebetween by this tibet cinnamon bark groove form touch, reduce friction as far as possible and reduce to rock.Described connector moves the muscle position feature 2016 of shell 204 by muscle position feature 2042 matching connector inner casing 201, shell 204 is moved freely resetting after axial-rotation 90 degree (as shown in Figure 10) to stop connector, moving shell 204 as needed connector to reset, needing to apply certain reciprocal moment of torsion between.
As shown in Figure 2, described electrode connecting end 1 limits the position of four Electrode connection contacts 111 by the profile of seal wire handle 10, and profile is corresponding with the opening shape of self-locking connector 20 simultaneously.Electrode connection contact 111 is column type, load in the process of self-locking connector 20 and first can be pressed into U-shaped contact spring 202 with less cross section, initial cross-sectional width is much smaller than U-shaped opening size, can be very smooth so coordinate, along with the increase of cross-sectional width, strut contact spring 202 gradually, and block diametrical position completely, ensure reliably to connect.
As shown in Figure 3, described test extension lead plug end 3 is substantially identical with electrode connecting end 1 profile, can regard the zoarium of seal wire handle 10 and electrode contacts 111 as, it is identical with the fit form of self-locking connector 20 and the fit form of above-mentioned electrode connecting end 1 and self-locking connector 20.
As shown in Figure 9, after described electrode connecting end 1 is pressed into the groove of self-locking connector 20, blocks seal wire handle 10 by the muscle position feature 2011 that connector inner casing 201 stretches out, stop it to eject, prevent it from hindering connector to move the rotation of shell 204.As shown in Figure 10, be the state of the final locking of self-locking connector 20.
As shown in figure 11, described cable plug end 22 protects terminal, in order to avoid cause damage when being subject to impacting by the muscle position feature 221 at terminal 222 two ends.When coordinating with testing stimulus device 4, muscle position feature 221 is inserted in the square hole feature 401 of testing stimulus device 4, and terminal 222 inserts in the socket end 402 of testing stimulus device 4.Thus complete the connection of whole measurement circuit.
