The connector 20 is provided with a seal groove 2031 communicating with the mounting groove 1012, and the seal 50 penetrates through the seal groove 2031 so that the seal 50 is completely accommodated in the seal groove 2031 and the mounting groove 1012.

It is understood that the number of connectors 20 may be one or more, and the specific number is not limited in the present utility model.

Referring again to fig. 1-3, in one embodiment, the first housing portion 101 includes a bottom plate 1014 and a side plate 1013 disposed about the bottom plate 1014. The plurality of side plates 1013 are provided, the plurality of side plates 1013 define a mounting cavity 1011, and the bottom plate 1014 is provided to cover an end of the plurality of side plates 1013 away from the second housing 102, so that the bottom plate 1014 closes an end of the mounting cavity 1011 away from the second housing 102. The first housing 101 may be formed by joining a plurality of side plates 1013 and a bottom plate 1014 together, or may be formed by integral molding.

Each section of the mounting groove 1012 is located at an end face of each side plate 1013 close to the second housing portion 102, respectively. The sections of the mounting groove 1012 communicate with each other. Referring to fig. 2 to fig. 4, in an embodiment, a through groove 1015 is formed on a side plate 1013 of the first housing portion 101, and the through groove 1015 penetrates through the side plate 1013 and communicates with the mounting cavity 1011. The connector 20 is inserted into the through groove 1015, and the middle section of the connector 20 is accommodated in the through groove 1015, and both ends of the connector 20 are exposed out of the through groove 1015.

Referring to fig. 3 to 5, in an embodiment, the connector 20 includes a protective housing 204, a first limiting portion 201, a supporting portion 203, and a second limiting portion 202. The protective shell 204 is exposed to the first housing portion 101 and is configured in a hollow cylindrical structure. The protective shell 204 has opposite ends.

The abutting portion 203 is formed by extending outward from the middle of the end face of one end of the protective case 204 in a direction away from the protective case 204. At least one of the upper and lower opposite surfaces of the abutting portion 203 is coplanar with the corresponding upper and lower opposite surface of the protective case 204. The width of the abutting portion 203 is smaller than the width of one end of the protective case 204 connected thereto. The first limiting portion 201 is in an annular sheet-shaped arrangement, and extends outwards from the end surface edge of the supporting portion 203 away from the protective shell 204. The outer contour of the first limiting portion 201 exceeds the outer contour of the abutting portion 203 connected with the first limiting portion. The second limiting portion 202 is arranged in a sheet shape, and extends downwards from the protective shell 204 towards the end face of the first limiting portion 201. The first limiting portion 201 and the second limiting portion 202 are respectively located at two opposite ends of the supporting portion 203, and the outer contour of the second limiting portion 202 downward and outward exceeds the outer contour of the supporting portion 203 downward and outward. In this way, the abutting portion 203, the first limiting portion 201 and the second limiting portion 202 together form a concave annular groove structure.

In particular, the protective shell 204, the first limiting portion 201, the abutting portion 203 and the second limiting portion 202 are integrally formed, so as to improve structural stability of the connector 20.

When the connector 20 is mounted to the first housing 101, the abutting portion 203 is engaged with the through groove 1015, and the first limiting portion 201 and the second limiting portion 202 are exposed from the through groove 1015. The thickness of the abutting portion 203 is the same as the groove depth of the through groove 1015, so that the side surface of the first limiting portion 201 facing the abutting portion 203 abuts against the side surface of the corresponding side plate 1013, and the side surface of the second limiting portion 202 facing the abutting portion 203 abuts against the side surface of the corresponding side plate 1013. Therefore, the side plate 1013 is clamped between the first limiting portion 201 and the second limiting portion 202, so that the connector 20 is clamped and fixed with the first housing portion 101, and the problem of loosening in the plugging process of the connector 20 is reduced.

Meanwhile, one end of the abutting portion 203 away from the second housing portion 102 abuts against the bottom wall of the through groove 1015 away from the second housing portion 102, so that the abutting portion 203 is supported in the through groove 1015.

It should be noted that, according to the above description, since the size of the abutting portion 203 is smaller than that of the first limiting portion 201 and the second limiting portion 202, the portions of the first limiting portion 201 and the second limiting portion 202 beyond the abutting portion 203 abut against the side plate 1013, and the connector 20 is fixed to the side plate 1013.

In particular, the side surface of the first limiting portion 201 and the second limiting portion 202 facing the second housing portion 102 is flush with the end surface of the side plate 1013, so that the first limiting portion 201 and the second limiting portion 202 cannot protrude from the side plate 1013 to affect the installation of the first housing portion 101 and the second housing portion 102.

Referring to fig. 2 to fig. 4, in an embodiment, a sealing groove 2031 is disposed on a side of the abutting portion 203 facing the second housing 102, and is formed by recessing inward from a side of the abutting portion 203 facing the second housing 102. Both ends of the seal groove 2031, which are provided opposite to each other in the width direction of the side plate 1013, communicate with the through groove 1015 to form a closed ring groove body, so that the seal 50 is completely accommodated in the seal groove 2031 and the mounting groove 1012. In addition, the groove width and the groove depth of the seal groove 2031 are the same as those of the mounting groove 1012, and the junction of the seal groove 2031 and the mounting groove 1012 smoothly transitions. The groove width refers to the width of the seal groove 2031 and the mounting groove in the width direction of the side plate 1013, and the groove depth refers to the depth of the seal groove 2031 and the mounting groove in the thickness direction of the side plate 1013.

In particular, the through groove 1015 is formed from the end surface of the side plate 1013 facing the second housing portion 102 toward the side away from the second housing portion 102, so that the through groove 1015 can communicate with the mounting groove 1012. When the abutting portion 203 is mounted in the through groove 1015, one side of the abutting portion 203 facing the second housing portion 102 is flush with one end of the side plate 1013 facing the second housing portion 102, and two outer walls of the abutting portion 203 opposite to each other in the width direction of the side plate 1013 are respectively abutted against two inner walls of the through groove 1015 opposite to each other in the width direction of the side plate 1013, so that the sealing groove 2031 formed in the abutting portion 203 can smoothly communicate with the mounting groove 1012 to form a closed ring groove.

Referring to fig. 2 to fig. 4, in an embodiment, a positioning groove 1016 is formed on a surface of the exposed side of the connector 20 of the first housing portion 101, and a portion of the second limiting portion 202 is disposed in the positioning groove 1016. The positioning groove 1016 is formed by inwards sinking the side plate 1013 away from the mounting cavity 1011 at the position corresponding to the through groove 1015, and the depth of the inwards sinking of the positioning groove 1016 is smaller than the thickness of the side plate 1013. The positioning groove 1016 is communicated with the through groove 1015, and the groove width of the positioning groove 1016 along the width direction of the side plate 1013 is larger than that of the through groove 1015, so that the second limiting portion 202 is prevented from entering the through groove 1015 from the positioning groove 1016. The second limiting portion 202 is adapted to the positioning slot 1016, so as to clamp the second limiting portion 202 in the positioning slot 1016.

In particular, the side surface of the second limiting portion 202 away from the first limiting portion 201 is flush with the side surface of the side plate 1013 close to the protective case 204, so as to ensure that the second limiting portion 202 is not exposed out of the positioning slot 1016.

Referring to fig. 3 to 5, in an embodiment, the connector 20 further includes a mounting plate 206 and a plurality of pins 207 disposed in the first housing 101. The mounting plate 206 has a plate-shaped structure, and is formed by protruding from the surface of one side of the first limiting portion 201 away from the second limiting portion 202 in a direction away from the second limiting portion 202, and the mounting plate 206 and the first limiting portion 201 may be integrally formed.

Mounting plate 206 is positioned within mounting cavity 1011 and mounting plate 206 is attached to a side of circuit board 40 remote from bottom plate 1014. The plurality of pins 207 are fixedly arranged on the mounting plate 206, so that the plurality of pins 207 can be positioned and mounted with the circuit board 40 through the mounting plate 206.
