Description

Technical Field

[0001] This utility model relates to the field of PTC electric heater technology, specifically to a ceiling-mounted air conditioner auxiliary heater bracket. Background Technology

[0002] PTC heaters are crucial components in air conditioning equipment. A typical PTC heater consists of two fixed supports connected to a heating element in the middle, and is then attached to the interior of the air conditioning unit via the supports. Current PTC heater supports consist of two parts: an injection-molded part that connects to the heating element and a sheet metal part that connects to the air conditioner. These two parts need to be manufactured separately and assembled during production. Alternatively, the fixed support may consist of a cavity housing the heating element and a cover for that cavity, again requiring the separate manufacture and assembly of two parts, resulting in low production efficiency.

[0003] For example, Chinese patent publication CN104378852A discloses a PTC heater bracket, including a bracket body and a cover. The bracket body forms a cavity, which is divided into an electrical protection component receiving cavity and a PTC heater mating cavity by a partition wall. A PTC heater insertion port is provided on the right side of the bracket body, and a positioning post extends and is installed on the left wall. The partition wall is single and located at the right end of the cavity. The electrical protection component receiving cavity is also single, and the PTC heater mating cavity is located between the partition wall and the front wall of the bracket body. A heat-diffusing fin support cover on the right end face of the bracket body mates with the bracket body and seals the upper part of the heat-diffusing fin support cavity. The left end of the cover forms an electrode insulating partition plate that extends into the cavity. This invention can support the heat-diffusing aluminum fins and protect electrical components, but the bracket body still needs to be connected to the cover, requiring the manufacture and assembly of two parts.

The junction box slot is used to fix the electrical components of the heating assembly, the wire hole can be used to pass through the wire harness, and the wire clamping claws are used to hold the wire harness.

[0010] The junction box slot includes a junction box baffle and a stop block, and the ratio of the height of the stop block to the height of the junction box slot is 9% to 11%. The height of the junction box slot is set according to the height of the electrical components of the heating assembly, and the height of the stop block is set so that the electrical components can be easily pushed into the junction box slot and fixed.

[0011] The first slot contains two mating blocks arranged vertically and vertically, with a wire splitting hole between the two mating blocks. A wire splitting plate is located on the side of the wire splitting hole opposite to the mating block. The shape of the mating blocks is set according to the end shape of the heating component. The wire splitting hole and the wire splitting plate facilitate the differentiation and routing of the heating component's wiring harness.

[0012] Both the first slot and the second slot are provided with reserved slots.

[0013] Both the first support portion and the second support portion are provided with air conditioning connection holes.

[0014] It also includes a heating component, with its two ends inserted into the first slot and the second slot respectively.

The first bracket 100 and the second bracket 200 are integrally injection molded.

[0032] The first bracket 100 and the second bracket 200 are both integrally injection molded, reducing the manufacturing process steps. They are connected to the air conditioner through the first support part 102 and the second support part 202, respectively. The first slot 101 and the second slot 201 are respectively connected to the two ends of the heating component 300 and fixed by screws, which can achieve reliable support for the heating component 300.

[0033] Reference Appendix Figures 1 to 3 Both the first bracket 100 and the second bracket 200 are box-shaped with openings on both sides, and each has a partition inside. The partition of the first bracket 100 is a first partition 103, which forms a first slot 101 at one end of the first bracket 100's interior, and a first support portion 102 at the other end. The outer side of the first support portion 102 has a connecting seat 400 and a rib 500.

(See attached diagram) Figure 3 The overall shape of the cable collection hole 106 is an inverted L-shape, with rounded corners at both bottom. After the first bracket 100 is fixed, the wire harness passing through the cable collection hole 106 overlaps at the bottom of the cable collection hole 106. The rounded corners facilitate the placement of the wire harness and prevent scratches on the outer sheath of the wire harness. The cable groove 104 penetrates the surface of the first bracket 100 where the cable collection hole 106 is located.

[0037] Example 2

[0038] This implementation further refines the structural features of hub module 105. See Appendix for further details. Figure 1 and 2 The first support 100 and the second support 200 are arranged opposite to each other. The first support 100 includes a first slot 101 and the second support 200 includes a second slot 201. The first support 100 has a first support portion 102 and the second support 200 has a second support portion 202. Both the first support portion 102 and the second support portion 202 are provided with a connecting seat 400 and a rib plate 500. A first partition plate 103 is provided between the first slot 101 and the first support portion 102. A wire groove 104 is opened on the first partition plate 103. The first support 100 and the second support 200 are integrally injection molded.

[0039] The first partition 103 is located on one side of the first support part 102 and has a cable collection module 105. The first support part 102 has a cable collection hole 106, which is correspondingly arranged with the cable collection module 105. The cable collection module 105 includes a cable box slot 107 and a wire through hole 108, and a cable clamping claw 109 is provided between the cable box slot 107 and the wire through hole 108.

[0040] Reference Appendix Figure 1 , 3 4. The cable management module 105 includes a cable box slot 107 and a wire hole 108, with a cable clamping claw 109 between the cable box slot 107 and the wire hole 108. The cable box slot 107 is used to clamp and fix electrical components, and the wire hole 108 is used to pass through the wire harness, penetrating the surface of the first bracket 100 where the cable management hole 106 is located. The cable clamping claw 109 is divided into a front claw and a rear claw, which are staggered. When viewed from the side of the first bracket 100, the cable clamping claw 109 appears as a pair of claws. In reality, the front claw and the rear claw are staggered along the internal depth direction of the first bracket 100. The advantage of this arrangement is that it is more convenient to fix the wire harness, and due to the rigidity of the wire harness itself, it is not easy to fall off after being fixed by the cable clamping claw 109.
