The outdoor unit of the air conditioner is installed in an outdoor environment, and the junction box is easy to enter water in rainy and snowy days, so that the air conditioner is in fault. In order to avoid the terminal box of air conditioner to intake, disclose a terminal box in the relevant art, including the box body that has a box body opening, set up guiding gutter around the box body opening and be used for covering the box body open-ended apron, the cover is equipped with outer sealing strip between guiding gutter and the box body opening, still including setting up the baffle in the box body, the baffle separates into the wiring district and the isolation district of lower part on upper portion with the inner space of box body, has seted up on the baffle and has been used for supplying the cable to extend to the first trompil of wiring district by the isolation district. The related art has a problem in that the air conditioner outdoor unit is used in an outdoor environment, and the junction box still has a risk of water inflow after the sealing strip is aged and deformed.

In order to reduce the risk of water leakage of the junction box 10, referring to fig. 1-6, an embodiment of the disclosure provides a junction box 10 for an air conditioner outdoor unit, which includes a box body 100 and a box cover 200, wherein the box body 100 is provided with a junction window 101, and the box body 100 is configured with a sealing groove 102 along the circumferential direction of the junction window 101; the box cover 200 is openably and closably provided at the connection window 101, the box cover 200 is configured with a sealing rib 220, and the sealing rib 220 of the box cover 200 is inserted into the sealing groove 102 of the box body 100.

The junction box 10 is provided in an air conditioner outdoor unit for connecting a power input harness and a control harness.

The junction box 10 includes a box body 100 and a box cover 200, the box body 100 is configured with a receiving space, and the junction terminal 300 is disposed in the receiving space. The box body 100 is provided with a wiring window 101, the box cover 200 is arranged on the wiring window 101 in an openable and closable manner, and the box cover 200 is opened to operate the wiring terminal 300 in the junction box 10.

Along the circumference of the wiring window 101, the wiring box 10 is configured with a circle of sealing grooves 102, and the depth direction of the sealing grooves 102 is along the depth direction of the wiring window 101. The cover 200 is configured with a ring of sealing ribs 220 corresponding to the sealing groove 102, and when the cover 200 is covered on the wiring window 101, the sealing ribs 220 are embedded into the sealing groove 102 to seal the wiring box 10.

In the position where the sealing groove 102 is abutted with the sealing rib 220, rainwater is required to pass through a slit along the height direction of the sealing rib 220 and turn by 180 ° when entering the interior of the junction box 10 through sealing, and the rainwater is small in thickness and long in travel. Under the surface tension of the rainwater and viscous force with the sealing rib 220 and the sealing groove 102, the sealing is difficult to break through into the junction box 10. With such an arrangement, the waterproof effect of the junction box 10 can be further improved.

With the junction box 10 provided by the embodiment of the present disclosure, the sealing rib 220 and the sealing groove 102 cooperate to improve the waterproof sealing effect of the junction box 10; the sealing rib 220 and the box cover 200 are made of the same material, so that the sealing rib is not easy to fail due to aging; in addition, the matching of the sealing rib 220 and the sealing groove 102 is also beneficial to the installation and positioning of the box cover 200.

Optionally, the height of the sealing rib 220 extending from the lid 200 is greater than the depth of the sealing groove 102, and the end of the sealing rib 220 abuts the bottom of the sealing groove 102.

The end of the sealing rib 220 abuts against the bottom of the sealing groove 102, so that the water stopping effect of the sealing rib 220 can be improved, and the sealing waterproof effect of the junction box 10 can be further improved.

Optionally, the sealing ribs 220 are interference fit with the sealing groove 102.

The sealing rib 220 is an interference fit with the sealing groove 102, i.e., the thickness of the sealing groove 102 is greater than the width of the sealing groove 102. After the cap 200 is mounted on the case body 100, a portion constituting the sealing groove 102 is elastically deformed to a certain extent, so that the sidewall of the sealing groove 102 can be more closely adhered to the sealing rib 220. This reduces the gap between the sealing rib 220 and the sealing groove 102, so that the sealing rib 220 and the sealing groove 102 can perform a sealing and waterproofing function better.

Optionally, the cover 200 is provided with a shielding edge 210 extending along the circumference of the wiring window, and the shielding edge 210 is attached to the box body 100.

The depth direction of the sealing groove 102 is along the depth direction of the case 100, and the height direction of the sealing rib 220 is along the depth direction of the sealing groove 102. The shielding edge 210 extends in a direction that covers the mounting window or sealing groove 102. For rain that splashes directly onto the junction box 10, the shielding edge 210 can block a substantial portion of the rain.

The shielding edge 210 is attached to the case 100, and a gap between the shielding edge 210 and the case 100 is small. Thus, it is difficult for rainwater to continue to penetrate inward through the gap between the shielding edge 210 and the case 100 under the action of the self-liquid surface tension and viscous force. While a small portion of the rain water that permeates inwardly along the gap between the shielding edge 210 and the case 100 may be stopped by the sealing rib 220 and the sealing groove 102. With such arrangement, rainwater penetrating into the sealing groove 102 can be reduced, and the waterproof sealing effect of the junction box 10 is further improved by the multi-stage sealing of the shielding edge 210 and the sealing rib 220.

Optionally, the box body 100 is recessed inwards to form a sink, the wiring window 101 is opened in the sink, the sealing groove 102 is configured in the sink, and the shielding edge 210 of the box cover 200 is attached to the bottom of the sink.

One surface of the box body 100 provided with the wiring window 101 is recessed inwards to form a sink, and the wiring window 101 is arranged on the sink. The sealing groove 102 is configured on the sink, and the shielding edge 210 of the box cover 200 is attached to the bottom of the sink. The box cover 200 is inserted into the sink corresponding to the mounting window. With this arrangement, the outward facing surface of the junction box 10 can have a flat appearance, thereby facilitating installation of the junction box 10 and ancillary equipment in the vicinity of the junction box 10.

Optionally, a hanging hole 103 is formed at the bottom of the sinking groove; the cap 200 is constructed with a hanging tab 230, and the hanging tab 230 is matched with the hanging hole 103 to fix the cap 200 to the case 100.

In order to better fix the box cover 200 to the box body 100, a hanging hole 103 is formed at the bottom of the sink of the box body 100, and a hanging lug 230 of the box cover 200 is matched with the hanging hole 103. When the box cover 200 is installed, the fixing of the box cover 200 can be realized through the hanging lugs 230 and the hanging holes 103, so that the box cover 200 is convenient to install.

Optionally, the hanging tab 230 includes a clamping portion 231, where the clamping portion 231 is clamped to an inner wall of the hanging hole 103 of the box body 100.

This prevents the lugs 230 of the cap 200 from being removed from the hanging holes 103.

Optionally, the hanging tab 230 further includes an inclined guiding portion 232, and when the hanging tab 230 is inserted into the hanging hole 103, the hanging tab 230 moves along the locking direction of the locking portion 231 under the guiding action of the guiding portion 232.

When the case body 100 is mounted, the hanging lugs 230 are aligned with the hanging holes 103, and the case cover 200 is pushed in the depth direction of the case body 100. The hanger 230 moves along one radial line of the hanging hole 103 under the guiding action of the guiding portion 232, so that the engaging portion 231 abuts against the inner wall of the hanging hole 103. With such an arrangement, the installation of the cap 200 is facilitated.

Alternatively, the number of the hanging holes 103 is plural, and the cover 200 is configured with a plurality of hanging lugs 230 corresponding to the plurality of hanging holes 103.

This allows the box cover 200 to be more firmly mounted to the connection window 101 of the box body 100 and allows the sealing rib 220 to be uniformly inserted into the sealing groove 102 at various positions.

Optionally, one end of the box cover 200 is provided with a clamping strip 240 in an extending manner, and when the box cover 200 is installed on the box body 100, the clamping strip 240 is clamped on the inner wall of the installation window of the box body 100.

When the box cover 200 is mounted on the box body 100, the hanging lugs 230 are aligned with the hanging holes 103, and the clamping strips 240 extend into the mounting window. The box cover 200 moves along a radial line of the hanging hole 103 under the guiding action of the guiding part 232 of the hanging lug 230, that is, the whole box body 100 moves along the plane where the mounting window is located, and the clamping strip 240 moves and abuts against the inner wall of the mounting window of the box body 100. With the arrangement, the clamping strip 240 and the hanging lugs 230 are used for fixing the box cover 200 to the box body 100, so that the fixing effect of the box cover 200 is improved.

Optionally, the box cover 200 is provided with a first bolt hole 260, and the box body 100 is provided with a second bolt hole 105 corresponding to the first bolt hole 260.

After the engagement portion 231 of the hanger 230 is engaged with the inner wall of the mounting window of the case 100, the first bolt hole 260 is aligned with the second bolt hole 105. Bolts or screws are inserted into the first bolt holes 260 and the second bolt holes 105, thereby achieving the fixation of the case 100 and the case 100. Threading screws or bolts can limit the movement of the box cover 200 along the plane of the wiring window 101, so as to cooperate with the hanging lugs 230 and the hanging holes 103 to fix the box cover 200 to the box body 100. With such an arrangement, the fixing effect of the junction box 10 to the box cover 200 can be improved. The form of the screw being matched with the hanging lugs 230 can reduce the number of screws, and is beneficial to the disassembly and assembly of the box cover 200. The box cover 200 is pre-fixed through the hanging lugs 230 and the hanging holes 103, so that the box cover 200 and the box body 100 are mounted and positioned.

Optionally, the shielding edge 210 is provided with a first bolt hole 260, and the bottom of the sinking groove is provided with a second bolt hole 105 corresponding to the first bolt hole 260.

Optionally, a mounting window is provided on a side of the case 100.

If the installation window is opened at the top of the box body 100, the rainwater sprayed on the box cover 200 of the junction box 10 is more, and the water inlet risk is high. If the installation window is opened at the bottom of the box body 100, the connection operation of the junction box 10 is difficult. The installation window is opened at the side of the box body 100, so that the water inflow risk of the junction box 10 can be reduced, and the junction operation of the junction box 10 is facilitated.

Optionally, the fastening strip 240 is configured on a first side of the lid 200, the first tab 230 is configured on a second side of the lid 200, the second tab 230 is configured on a third side of the lid 200, the second side is adjacent to the first side, and the third side is opposite to the second side and adjacent to the first side.

With the arrangement, the stress of the box cover 200 is uniform, and the clamping strip 240 can be matched with the hanging lugs 230 better to fix the box cover 200.

Optionally, the first side corresponds to a top of the mounting window.

When the cap 200 is mounted to the case body 100, the cap 200 is in a form of sliding up and down with respect to the case body 100. The up-and-down sliding form can make the disassembly and assembly of the box cover 200 more convenient.

Alternatively, the hanging lugs 230 are disposed at one end of the box cover 200, and the first screw holes are formed at the other end of the box cover 200.

The first screw hole is formed on a fourth side of the box cover 200, and the fourth side is opposite to the first side. The hanging lugs 230 are positioned at the upper end, and the first screw holes are positioned at the lower end of the box cover 200. Such a top-bottom mating pattern may allow an electronically controlled screw or bolt to better function to limit movement of the lid 200.

Optionally, a plurality of wire vias are formed on the fourth side of the box cover 200.

The fourth side of the box cover 200 is provided with a wire passing hole through which the power harness and the control harness of the junction box 10 can be connected.
