[0029] The following combination Figures 1 to 4 , describing a simple and highly sealed power supply housing structure of an embodiment of the present utility model.

[0030] A highly sealed power supply housing structure with a simple structure, comprising a power supply main housing 1, a power supply side cover 2, and incoming and outgoing wires with sealing plugs 3 formed on the sheath; the power supply side cover 2 is tightly mounted on the front and rear ends of the power supply main housing 1;

[0031] The power supply side cover 2 is provided with a wire interface 21 , and the sealing plug 3 is used for tightly sealing the wire interface 21 .

[0032] The present invention proposes a preferred embodiment of a simple structure high-sealed power supply housing structure, such as Figures 1 to 2 As shown, the power supply casing is composed of the power supply main shell 1, the power supply side cover 2, and the incoming and outgoing wires with sealing plugs 3 formed on the sheath. The casing structure has few parts, the operation process is simple, the production efficiency is high, and the material cost and processing cost of the parts are low.

[0033] Specifically, the power supply side cover 2 is tightly covered on the front and rear ends of the power supply main shell 1, forming a closed internal space of the power supply; the incoming wires (or outgoing wires) are connected to the inside and outside of the internal space of the power supply from the wire interface 21 of the front or rear end power supply side cover 2, and at the same time, the sealing plug 3 on the incoming wire (or outgoing wire) is tightly sealed with the wire interface 21 to ensure the closure of the internal space of the power supply, so that the interior is filled with waterproof silicone material to completely cover the circuit board, and the waterproof level can reach IP65 and above.

[0034] Furthermore, a notch is opened from the bottom end to the center of the power side cover 2 to form a wire interface 21; the sealing plug 3 can slide into the wire interface 21 from the bottom end of the wire interface 21 and tightly wrap the wire interface 21.

[0035] In this embodiment, because the sealing plug 3 is pre-formed on the sheath of the incoming wire and the outgoing wire, the sealing plug 3 is formed integrally with the wire and cannot be disassembled for installation. In order to facilitate the quick installation of the sealing plug 3 and simplify the operation process, a notch is opened from the bottom end to the center of the power supply side cover 2 to form a wire interface 21. Before the power supply side cover 2 is covered on the front end or rear end of the power supply main shell 1, the sealing plug 3 is first slid from the bottom end of the wire interface 21 into the wire interface 21, and then the wire interface 21 is tightly wrapped to complete the sealing of the wire interface 21.

[0036] Furthermore, the main shell 1 of the power supply includes an upper shell 11 and a lower shell cover 12; the bottom end of the upper shell 11 and the lower shell cover 12 are snap-connected, the top surface of the lower shell cover 12 and the bottom of the sealing plug 3 are tightly against each other, and the power supply side cover 2 covers the front end of the upper shell 11 and the lower shell cover 12, or the power supply side cover 2 covers the rear end of the upper shell 11 and the lower shell cover 12.

[0037] In this embodiment, in order to facilitate the filling of waterproof silicone material into the main shell 1 of the power supply, and the sealing plug 3 can slide into the wire interface 21 from the bottom end of the wire interface 21 of the power supply side cover 2, the main shell 1 of the power supply is preferably composed of an upper shell 11 and a lower shell cover 12. When the power supply side cover 2 is tightly covered and the sealing plug 3 is tightly sealed to the wire interface 21, the waterproof silicone material is filled into the groove formed by the upper shell 11 and the power supply side cover 2. Finally, the lower shell cover 12 is buckled into the bottom end of the upper shell 11, so that the front end or rear end of the lower shell cover 12 is covered by the power supply side cover 2, completing the tight covering and forming a closed space. At the same time, the top surface of the lower shell cover 12 and the bottom of the sealing plug 3 are tightly against each other, and the lower shell cover 12 is used to limit the sealing plug 3.

[0038] Furthermore, the sealing block 3 includes a first blocking block 31, a second blocking block 32 and a blocking slide 33; the first blocking block 31 is convex on the front side of the sealing block 3, the second blocking block 32 is convex on the rear side of the sealing block 3, and the blocking slide 33 is concave between the first blocking block 31 and the second blocking block 32;

[0039] The blocking slide 33 slides into the wire interface 21 and is tightly against the wire interface 21 . The back of the first blocking block 31 is tightly against the outer surface of the power side cover 2 , and the front of the second blocking block 32 is tightly against the inner surface of the power side cover 2 .

[0040] In this embodiment, Figure 3 As shown, in order to seal the wire interface 21, the shape of the sealing plug 3 is preferably set as follows: a first sealing block 31 is formed by convexly raising on the front side, a second sealing block 32 is formed by convexly raising on the rear side, and a sealing slide 33 is formed between the first sealing block 31 and the second sealing block 32; thus, after sliding into the wire interface 21 through the sealing slide 33 and tightly abutting against the wire interface 21, the back of the first sealing block 31 is tightly abutted against the outer surface of the power supply side cover 2, and the front of the second sealing block 32 is tightly abutted against the inner surface of the power supply side cover 2, which tightly wraps the wire interface 21 and improves the sealing performance of the wire interface 21.

[0041] Furthermore, the bottom end of the blocking slide 33 is longer than the bottom end of the second blocking block 32 , the top surface of the lower shell cover 12 and the bottom surface of the second blocking block 32 are tightly against each other, and the front or back of the lower shell cover 12 is tightly against the back of the blocking slide 33 .

[0042] In this embodiment, because the sealing plug 3 is installed, the first sealing block 31 is located on the inner side of the power supply side cover 2. After the power supply side cover 2 covers the upper shell 11 and the lower shell cover 12, in order to ensure the sealing of the power supply shell, the lower shell cover 12 can limit the sealing plug 3; so the bottom end of the sealing slide 33 is designed to be longer than the bottom end of the second sealing block 32, so that the top surface of the lower shell cover 12 can be tightly against the bottom surface of the second sealing block 32 from the inner side of the power supply side cover 2, and at the same time, the front or back of the lower shell cover 12 is tightly against the back of the sealing slide 33 to complete the sealing.

[0043] Furthermore, the power side cover 2 is riveted to the front end or the rear end of the upper shell 11 .

[0044] In this embodiment, in order to enable the power side cover 2 to be tightly covered on the front end or rear end of the power main shell 1, the power side cover 2 is preferably fixed to the main part of the power main shell 1 through various riveting methods to make the connection between the two more firm, that is, the power side cover 2 is riveted to the front end or rear end of the upper shell 11.

[0045] Furthermore, at least one pair of riveted protrusions 111 is provided on the outer side of the front end or the outer side of the rear end of the upper shell 11, and the paired riveted protrusions 111 are symmetrically arranged on the left and right sides;

[0046] The power supply side cover 2 is provided with a rivet groove 22 corresponding to the rivet protrusion 111 , and the rivet groove 22 and the rivet protrusion 111 are riveted to each other.

[0047] In this embodiment, Figure 4 As shown, the front or rear end of the power side cover 2 and the upper shell 11 are preferably riveted together by riveting the rivet grooves 22 and the rivet protrusions 111 (and the riveting is more secure when the left and right sides are symmetrically arranged) (such as a concave-convex fitting connection). Therefore, after the power side cover 2 is assembled in place, the rivet protrusions 111 can be punched out from the corresponding rivet grooves 22 inside the upper shell 11 to achieve riveting, and the riveting relationship is more secure.

[0048] Furthermore, the upper shell 11 is provided with a riveted limiting block 112 on the outer side of the riveted protrusion 111 .

[0049] In this embodiment, to prevent the rivet groove 22 from separating from the rivet protrusion 111 after the rivet groove 22 and the rivet protrusion 111 are riveted to each other, the upper shell 11 is provided with a rivet limit block 112 on the outer side of the rivet protrusion 111 for limiting the rivet groove 22 .

[0050] Furthermore, a first snap-on protrusion 113 tilted downward is provided on the outer side of the bottom end of the upper shell 11, and a second snap-on protrusion 121 tilted upward is provided on the inner side of the cover eave of the lower shell cover 12 corresponding to the first snap-on protrusion 113. The first snap-on protrusion 113 and the second snap-on protrusion 121 are snap-connected to each other.

[0051] In this embodiment, the snap connection relationship between the bottom end of the upper shell 11 and the lower shell cover 12 is preferably that the first snap protrusion 113 and the second snap protrusion 121 are snap-connected to each other. Because the upper shell 11 and the power side cover 2 are riveted relatively tightly, the lower shell cover 12 may easily get stuck when snapping together. Therefore, a downward-inclined first snap protrusion 113 is provided on the outer side of the bottom end of the upper shell 11, and an upward-inclined second snap protrusion 121 is provided on the inner side of the cover eave of the lower shell cover 12 corresponding to the first snap protrusion 113, so that the inclined surfaces can be used to guide each other when the two are snapped together, which facilitates the snapping together.

[0052] Furthermore, the sealing member 3 is made of elastic insulating material.

[0053] In this embodiment, since the parts in contact with the sealing plug 3 need to be tightly against each other to improve the sealing performance, the sealing plug 3 is preferably made of elastic insulating material, which can be used as a wire sheath and can achieve tight resistance by utilizing elasticity, such as silicone, rubber, etc.
