Preferably, the inner end of the strip-shaped protrusion T extends to the outer side of the flexible pressing ring 305 connected to the inside of the tailstock, and forms a longitudinal limit for the flexible pressing ring 305. Therefore, the stripe-shaped projection T of the present invention has two functions: firstly, a guiding function is realized for the relative sliding of the first connecting tailstock 302 and the second connecting tailstock 303; secondly, the fixing of the flexible extrusion ring 305 is limited and prevented from falling off.
Preferably, the depth direction of the sliding groove 301a-3 on the central fixing frame 301a is perpendicular to the depth direction of the accommodating groove 301 a-1.
Based on the above, the principle of connection and fastening of the harness connector 300 of the present invention to the first harness 100 and the second harness 200 is as follows:
when the first wire harness 100 and the second wire harness 200 respectively penetrate through the threading ports of the first connecting tailstock 302 and the second connecting tailstock 303, the first wire core 101 and the second wire core 102 of the first wire harness 100 can be divided into two branches by the branching head 301a-2 at one end of the central fixing frame 301a, and the two branches are respectively inserted into the insertion ports K-1 at one end of the first conductive pillar 301b and the second conductive pillar 301 c. Similarly, the third wire core 201 and the fourth wire core 202 of the second wire harness 200 can be divided into two branches by the branch connector 301a-2 at the other end of the central fixing frame 301a, and the two branches are respectively inserted into the sockets K-1 at the other ends of the first conductive pillar 301b and the second conductive pillar 301 c.
When one end of the connecting ring 304 is sleeved on the periphery of the second connecting tail seat 303 and the other end is rotatably connected with the first connecting tail seat 302 through threads, the first connecting tail seat 302 and the second connecting tail seat 303 can move in opposite directions under the guidance of the sliding groove 301a-3, and the flexible extrusion ring 305 can press the wire cores on two sides of the same wire dividing head 301a-2 on the guide slope surfaces 301a-22 on two sides of the wire dividing head 301a-2 respectively to realize compaction and fastening.
Because the first connecting tailstock 302 and the second connecting tailstock 303 can only slide linearly and oppositely but cannot rotate relatively, the movement mode can ensure that the flexible extrusion ring 305 can effectively extrude and fix the wire core linearly, and the defect that the wire core is twisted due to rotation is avoided.
In summary, the central fixing frame 301a of the present invention has at least the following functions:
the first step, two conductive columns on two sides of the first step are accommodated and fixed;
secondly, the two conductive columns on the two sides of the conductive column are isolated, so that the short circuit caused by mistaken touch is prevented;
thirdly, the central fixing frame 301a can play a role of linear guiding for the connecting tailstocks sleeved at the two ends of the central fixing frame, so that the two connecting tailstocks can only linearly move in opposite directions and can not relatively rotate, and the flexible extrusion ring 305 can be used for extruding and fixing the wire core;
fourthly, providing a guiding function for the wire harness to branch and form two wire cores after penetrating into the connecting tailstock;
fifthly, stress bearing surfaces (guide slope surfaces 301a-22) are provided for the extrusion and fixation of the flexible extrusion ring 305, namely the flexible extrusion ring 305 and the guide slope surfaces 301a-22 extrude and fix two wire core ends together.
The wire harness connector of the invention can be applied to a modularized FTU, and the specific mode is as follows:
integrating all modules and devices inside the existing FTU, and integrating main functional modules (including MCU, DSP, RAM, A/D digital-to-analog conversion and other chips) into automatic feeder terminal equipment; integrating a power supply module, an energy storage module (super capacitor) and a double alternating current switching module (relay) into power supply equipment; integrating a plurality of fuses into a whole protection module, and setting wires connected to each integrated module (an automatic feeder terminal device, a power supply device and a protection module) as wire harness ends with one exposed end; and between each integrated module, can carry out the quick grafting of grafting through pencil end and pencil connector and fix, consequently easy to assemble and dismantle the maintenance.
When equipment needs to be replaced and maintained, the wiring harness connector can be integrally replaced by pulling the wiring harness connector down, modularization operation and maintenance are achieved, efficiency is high, and error probability is low.
The protection module integrates a plurality of paths of fuses, the incoming line and the outgoing line adopt a plug-pull mode, and the protection module is simple to operate and high in reliability.
When FTU product needs to be assembled, only need one by one treat two integrated module on the pencil end through the pencil connector peg graft fixedly can, need not loaded down with trivial details wiring operation, easy operation, convenient, and the reliability is high.
