Embodiment
According to Fig. 1 to Fig. 6, the present embodiment is a kind of and instrumentation adapted multi-functional terminal, includes post
The main part 1 of shape, the slip chuck 2 for the body outer wall that is slidably located in is slidably connected at the briquetting 3 slided on the outside of chuck,
And it is connected to the spring 5 between slip chuck and main part.
The slip chuck is in integrally quadrangular shape.
The main part includes the instrument connector 11 of integrally connected successively, the first chuck connecting portion 12 and the second chuck
Connecting portion 13.
The end of the second chuck connecting portion forms banana head jack 134 along main part length direction；Described second
Chuck connecting portion side wall forms the more than one cylinder terminal perforation 133 vertical with main part length direction.
The slip chuck includes the first chuck 2a being slidably located in outside the first chuck connecting portion, is slidably located in the
The second chuck 2b outside two chuck connecting portions, and the connection strap 2c being integrally attached between the first chuck and the second chuck.
End face of the second chuck connecting portion close to the first chuck connecting portion side is Y type terminals clamping wall 132, described
First chuck one end is pushed against between Y type terminal clamping walls so that Y types end is formed between the first chuck and Y shape terminal clamping wall
Sub- clamping part.
The second jacket side wall is formed to be coordinated with the cylinder terminal clamp hole of clamp cylinders terminal with the perforation of cylinder terminal
201。
The briquetting includes press section, and is molded over the spacing dop installing plate at press section side two ends respectively；Institute
State and sliding block 31 is formed on the inwall of press section, upper end of slide block face is inclined-plane；The position of correspondence sliding block on the second jacket side wall
Form perforation 204；Beveled aperture 135 is formed on the wall of the second chuck connecting portion side.
The beveled aperture inner top surface is inclined-plane, and identical with upper end of slide block face angle of inclination；The upper end of slide block face with tiltedly
The inner top surface of face offsets, and sliding block lower surface offsets with the inner bottom surface perforated.
The beveled aperture meets claimed below：When pressing briquetting to extreme position, the cylinder terminal clamp hole and cylinder
Terminal perforation aligns.
Form and be molded on spacing dop 32, the relative side wall of second chuck two on each spacing dop installing plate
Limited location hole 202；The glade plane space slided for spacing dop is formed between the spacing hole and spacing dop；Spacing dop is not
Depart from ground to slide in spacing hole.
On the spacing dop installing plate U-lag, the spacing dop peace are offered positioned at the periphery of limiting card head
The part being located on dress plate in the middle of U-lag is bent inwards to form the spacing dop, and the end of spacing dop is pressed described in
Splenium, spacing dop can be slipped into the spacing hole such briquetting by its inclined internal face when mounted, limiting card
Spacing dop installing plate can produce certain deformation during head slips into spacing hole；And using spacing dop among process not
It can be disengaged with spacing hole.
In addition, the sliding block is located between slip chuck and main part, the effect of guide finger is served, makes slip chuck
It will not be circumferentially rotated with respect to main part, the perforation of cylinder terminal and cylinder terminal clamp hole is kept constant in the same direction.
Position on the first chuck connecting portion close to instrument connector forms a taper centring ring 121, taper
The summit of circular conical surface residing for centring ring is located at instrument connector side；First jackets inner wall forms a spring positioning
Shoulder 203；The spring is set on the first chuck connecting portion and both ends of the spring is against spring locating shoulder and taper centring ring
Between；Also, the external diameter of the widest part of the taper centring ring is less than the internal diameter at the most narrow place of the first chuck, the spring is taper
Spring.
The present embodiment fixes spring by taper centring ring, reduces parts, reduces cost.Volute spring is installed
When, the outer wall using the sleeve of tubulose by spring along taper centring ring is pushed away inward, and spring, which circumferentially produces deformation, becomes radius
Greatly, after the outer end of spring is completely by taper centring ring, outer spring end, which restores to the original state, is against the inner of taper centring ring
Face, does not fall out.
The cylindrical end period of the day from 11 p.m. to 1 a.m is being installed, press section is depressed into extreme position by user with thumb, and volute spring shrinks, described
Cylinder terminal clamp hole aligns with the perforation of cylinder terminal, it becomes possible to insert cylinder terminal, unclamps press section, because spring is produced
Pretightning force, can by cylinder terminal firm grip cylinder terminal perforate in.
Similarly, install Y type terminals when, press section is depressed into correct position by user so that Y type terminal clamping walls with
First chuck upper end has sufficient space to install Y type terminals, and now spring contraction, is installed after Y type terminals, unclamps press section, bullet
Y type terminals can be clamped between Y type terminal clamping walls and the first chuck by the pretightning force of spring.
The present invention is directly to contact connection when being connected with banana head, cylinder terminal, Y types terminal, in the absence of mediate contact
Situation, and cylinder terminal and Y types terminal connection when be matched for clamping tightly by sliding chuck with briquetting, connective stability is good,
The stabilization transmitted beneficial to signal, it is to avoid signal jump, the wild effect of interruption occur, beneficial to ensureing measuring accuracy.
