[0024] Example 1

[0025] Please see Figure 1 The outer shell provided by this utility model includes a first shell 1, a second shell 2 and a rib 3. The rib 3 is disposed on the first shell 1, and the second shell 2 is provided with a groove 4. When the first shell 1 and the second shell 3 are connected, the rib 3 and the groove 4 are interference fit to form a wire hole.

[0026] It is understandable that the connection between the first housing 1 and the second housing 2 can be in various ways, including bolts or welding. The interference fit between the rib 3 and the groove 4 can ensure the sealing when the wire hole is connected to the wire harness. When sealing the wire harness, sealant can be filled into the wire hole to further improve the overall sealing performance. The rib 3 and the first housing 1 can be an integral structure.

[0027] Please see Figure 2 In some embodiments, the first housing 1 includes a first body, and a first sealing groove 103 is provided on the end face of the first body. The rib 3 is correspondingly provided at the position of the first sealing groove 103. The second housing 2 includes a second body 201, and a second sealing groove 202 is provided on the end face of the second body 201. The groove 4 is correspondingly provided at the position of the second sealing groove 202. Correspondingly, the housing also includes a sealing ring, which fills the first sealing groove 103 and the second sealing groove 202, and the sealing ring is located between the rib 3 and the groove 4.

[0028] It is understandable that the sealing ring is engaged in the first sealing groove 103 and the second sealing groove 202, which can ensure the sealing of the connection between the first body and the second body 201.

[0029] Please continue reading. Figure 2 In some embodiments, the first body includes an upper shell portion 101 with at least two side snap-fit ​​pieces 102, the side snap-fit ​​pieces 102 being symmetrically arranged on both sides of the upper shell portion 101, and a first sealing groove 103 being disposed on the end face of the upper shell portion 101. The second body 201 includes a lower shell portion and at least two protruding snap-fit ​​blocks, the two protruding snap-fit ​​blocks being symmetrically arranged on the lower shell portion, and a second sealing groove 202 being disposed on the end face of the lower shell portion. The side snap-fit ​​pieces 102 are snapped and fixed to the protruding snap-fit ​​blocks.

[0030] It is understood that the side snap-fit ​​piece 102 may have snap-fit ​​holes and be an integral structure with the upper shell part 101. The protruding snap-fit ​​block may be adapted to snap-fit ​​holes or be an integral structure with the lower shell part. The protruding snap-fit ​​blocks are obliquely and symmetrically arranged on the lower shell part. Similarly, the side snap-fit ​​piece 102 is obliquely and symmetrically arranged on the upper shell part 101. The protruding snap-fit ​​block may be arranged in the recessed position of the lower shell part so that the side snap-fit ​​piece 102 does not protrude from the surface of the lower shell part. The connection between the first main body and the second main body 201 of this structure is quick and convenient. A connecting block may also be provided on the lower shell part for fixing the shell.

[0031] Please see Figure 1 In some embodiments, the rib 3 includes at least two rib plates 301 and a rib block 302. The two rib plates 301 are symmetrically arranged on both sides of the first sealing groove 103, and the rib plates 301 are provided with a first arc-shaped groove. The rib block 302 is disposed in the first sealing groove 103 and is located between the two rib plates 301. The rib block 302 is provided with a second arc-shaped groove, and the first arc-shaped groove is located above the second arc-shaped groove.

[0032] It is understandable that both the rib plate 301 and the rib block 302 can be trapezoidal in shape. The first arc groove can be set on the upper bottom of the rib plate 301, and the second arc groove can also be set on the upper bottom of the rib block 302. The purpose of the second arc groove being lower than the first arc groove is to prevent the sealing ring from protruding too much from the first arc groove when it is filled in the second arc groove. The shape of the groove 4 can be adapted to the shape of the rib plate 301. The upper bottom of the groove 4 can be provided with an arc shape adapted to the wire harness 5. The rib 3 of this structure can have a good sealing performance for the wire harness 5.

The antenna body 11 and the circuit board 10 are assembled together by SMT process, and the antenna body 11 and the circuit board 10 are located inside the housing. One end of the wiring harness 5 is connected to the circuit board 10, and the other end of the wiring harness 5 passes through the through hole formed between the protrusion 3 and the groove 4.

[0035] It is understandable that sealant can be filled between the wire harness 5 and the wire hole to improve the overall sealing performance. Positioning protrusions can also be provided on the inner wall of the upper shell 101 to position and limit the antenna body 11 and the circuit board 10.

[0036] Please see Figure 5 In some embodiments, the antenna also includes a shield 9 that covers the core components of the circuit board 10.

[0037] Understandably, the core components on circuit board 10 can be PMU, DC-DC converter, LDO, etc., which can achieve electrostatic and electromagnetic interference.

[0038] Please continue reading. Figure 5 In some embodiments, the antenna also includes a sound-dampening sleeve 7, which is fitted onto the wiring harness 5.

[0039] Understandably, the Silent Cotton Cover 7 can reduce noise and vibration transmission, while also providing waterproof and heat insulation effects.

[0040] Please see Figure 4 In some embodiments, the antenna also includes a tag 6, which is affixed to the wire harness 5.

[0041] Understandably, label 6 can be attached to the sound-dampening cotton sleeve 7 of wire harness 5 to mark the antenna information, and clips 8 can be provided at the end of wire harness 5 for connection and fixation with Rosenberger connector.

[0042] As can be seen from the above description, the shell and antenna provided by this utility model will not easily experience sealing failure, are not prone to aging, have good sealing stability, and have high sealing precision.
