Detailed Description

As shown in fig. 1, fig. 2, fig. 3, fig. 4, the utility model relates to a temperature control coupler lower seat, it is installed in the mounting hole of electrical heating base, including insulating lower seat shell 1 and install a plurality of wiring reed 3 in insulating lower seat shell electrode mounting groove 2, insulating lower seat shell 1 openly on be equipped with several spacer ring muscle 12 that central reference column 11, concentric circles set up respectively, between central reference column 11 and the adjacent spacer ring muscle, form coaxial alternate setting annular groove 5 between the adjacent two-stage spacer ring muscle, the one end of annular groove 5 is sealed, the other end is opened has the hydrophobic hole 6 that lacks that supplies wiring reed 3 coupling end to stretch into, keep away from wiring reed 3 position between hydrophobic hole 6 and the closed section on annular groove 5 and be equipped with the water guide recess 9 that communicates with the closed section, water guide recess 9 bottom surface on open and have wash port 8. The electrode mounting grooves 2 arranged on the back of the insulating lower seat shell at intervals comprise a live wire electrode mounting groove 2-1, a zero line electrode mounting groove 2-2 and a ground wire electrode mounting groove 2-3 positioned between the live wire electrode mounting groove 2-1 and the zero line electrode mounting groove 2-2, the wiring reed 3 comprises an L-pole wiring reed 3-1 arranged in the live wire electrode mounting groove 2-1, an N-pole wiring reed 3-2 arranged in the zero line electrode mounting groove 2-2 and a central grounding sheet 3-3 arranged in the ground wire electrode mounting groove 2-3, the front of the insulating lower seat shell 1 is provided with a central positioning column 11, an inner isolation ring rib, a first annular groove 5-1 for the L-pole wiring reed 3-1 to extend into between the central positioning column 11 and the inner isolation ring rib, and a second annular groove 5-1, And a second annular groove 5-2 for the N-pole wiring reed 3-2 to extend into between the inner isolation ring rib and the outer isolation ring rib.

The embodiment avoids the phenomena that the creepage distance generated by the coupling end of the inner wall of the hydrophobic lacking hole and the wiring reed is small to cause contact, the qualified rate of an overflow test is low and the like because the water flow, particularly the high-pressure water flow directly flows downwards along the inner wall of the hydrophobic lacking hole. The ring walls on two sides of the first ring groove 5 at the position of the drainage hole 6 are eaves 7 extending downwards, and the eaves 7 and the coupling end of the wiring reed 3 are in a suspended state. Eaves limit 7 can not only the separation water get into, and eaves limit 7 has the guide effect to rivers in addition, lets hydroenergy assemble along eaves limit 7 and drips from lower terminal surface, and lower terminal surface is narrow little, and the water droplet can't form sufficient adhesive force, can not amass on it, and unsettled fault setting makes and has sufficient safe space distance between eaves limit 7 lower bottom surface and the wiring reed, has effectively solved creepage distance and has aroused the potential safety hazard.

Meanwhile, the electric shock problem caused when a human body, particularly a hand touches the mounting hole of the electric heating base due to the fact that the conductive wiring reed is exposed or is too close to the mounting hole gap when the wiring reed, particularly the conductive wiring reed is assembled to the mounting hole of the electric heating base at the lower seat of the coupler is solved. The bottom of the insulating lower seat shell 1 of the embodiment is also provided with an outer isolation edge 10 which extends outwards from the electrode mounting groove 2 and covers and seals the upper part of the wiring reed 3, and when the whole machine is mounted, the outer isolation edge 10 covers and seals the wiring reed 3 below a panel of the whole machine without exposing. The bottom of the insulating lower seat shell 1 is provided with a peripheral annular table 13 annularly connected with an outermost level isolation annular rib, the outer isolation edge 10 is positioned below the peripheral annular table 13, the upper surface of the peripheral annular table 13 is in a descending level shape, namely, the peripheral annular table 13 comprises a first level table ring 131 matched with the base mounting hole in a fitting manner, and a second level table ring 132 connected to the peripheral edge of the first level table ring 131 and abutted to the edge of the base mounting hole. And the second-stage platform ring 132 is provided with an installation positioning groove 15 which is matched with and limited by the electric heater base bottom plate 3. The outer partition edge 10 completely partitions the conductive wiring reed 3 below the mounting hole, and the free end of the wiring of the conductive wiring reed is far away from the mounting hole, so that the safety is greatly improved, and the assembly is convenient. The design of the peripheral ring platform 13 can ensure that the lower seat of the coupler is stably connected with the mounting hole, thereby facilitating assembly and improving waterproofness.

The internal structure of this embodiment is rationally distributed, can improve the overflow test throughput of coupler, improves the security performance of electric coupler, has also promoted the security that electric coupler used under humid environment simultaneously.

Although the present invention has been described with reference to the specific embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
