The first fixing section 321 is fixed to the connection base 33, the second fixing section 322 is fixed to the control board 20, and the plug section 322 is electrically connected to the adjacent electronic module.

[0038] Specific reference Figure 1 , Figure 6 and Figure 7As shown, the first housing 11 is provided with a first through hole 110 at a position corresponding to the connection component 30, and the second housing 12 is provided with a second through hole 120 at a position corresponding to the connection component 30. The first terminal 31 is provided through the first through hole 110, and the second terminal 32 is provided through the second through hole 120 and protrudes from the second housing 12.

[0039] It is understandable that, according to the actual design requirements of the product, the first terminal 31 and the second terminal 32 are arranged in parallel along the connection seat 33 in a plurality and correspond one to one. The first through hole 110 is arranged as a strip hole extending along the arrangement direction of the first terminal 31, and is used to accommodate the clamping portion 312 of the first terminal 31. The second through hole 120 is arranged as a plurality of elongated holes along the arrangement direction of the second terminal 32, and is used to locate the plug section 323 of the second terminal 32.

By cutting the same material to form the first terminal 31 and the second terminal 32, materials can be effectively saved and costs can be reduced.

[0041] The technical solution of this embodiment is to arrange a connecting component 30 having a first terminal 31 and a second terminal 32 on the control board 20, and the first terminal 31 and the second terminal 32 are arranged opposite to the connecting seat 33 of the connecting component 30, wherein the clamping portion 312 of the first terminal 31 is passed through the first through hole 110 of the first shell 11, and the plug-in section 323 of the second terminal 32 is passed through the second through hole 120 and protrudes from the second shell 12, and the plug-in section 323 of the second terminal 32 can be plugged into and between two clips that are also provided with the first terminal in the adjacent electronic module, so as to realize the electrical connection between the two adjacent electronic modules, and also realize the expansion of the electronic module according to actual product requirements.

[0042] As another embodiment of the present invention, refer to Figure 1 , Figure 8 and Fig. 9 As shown, the control board 20 is provided with light-emitting components 201 on both sides facing the first shell 11 and the second shell 12. In order to realize the light-emitting display of the light-emitting component 201, the present embodiment has a light-emitting surface 121 integrally injection-molded at the top of the second shell 12 away from the second through hole 120, and the light-emitting surface 121 is covered with a decorative mask. Correspondingly, the inner sides of the first shell 11 and the second shell 12 are integrally injection-molded and convexly provided with a light-guiding portion 122 corresponding to the light-emitting surface 121. Among them, the light-guiding portion 122 is provided with an enclosure 1221 and a plurality of isolation plates 1222. The enclosure 1221 encloses a light-guiding space, and the isolation plates 1222 isolate the light-guiding space into a plurality of light-guiding channels 1223, which are similar to a fence-type structure. The isolation plates 1222 physically isolate the light-emitting components 201 to avoid the risk of cross-lighting. It can be understood that the light-emitting components 201 are installed one-to-one in each light-guiding channel 1223, and a light-emitting hole 1211 is provided at the position of each light-guiding channel 1223 corresponding to the light-emitting surface 121. The light-emitting direction of the light-emitting component 201 is perpendicular to the light-guiding direction of the light-guiding channel 1223. The light of the light-emitting component 201 is transmitted through the light-guiding channel 1223 to reach the light-emitting hole 1211, and irradiates the decorative mask to realize the luminous display.

[0043] The technical solution of this embodiment is to integrally mold a light guide portion in the first shell and the second shell respectively, and integrally mold a light-emitting surface corresponding to the light guide portion in the second shell. The light-guiding space between the light guide portion and the light-emitting surface is separated into relatively independent light-guiding channels by an isolation plate, so that the light-emitting components located on both sides of the control panel are arranged in their corresponding light-guiding channels. At this time, the light of the light-emitting components reaches the light-emitting hole after being transmitted through the light-guiding channels, and irradiates the decorative mask to realize the light-emitting display. This embodiment directly realizes the light-emitting display of the light-emitting components by integrally molding the light-guiding channels. It does not require additional components, light guide columns, and the assembly of the shell to achieve the purpose of light-emitting display. It also saves the step of manual assembly, reduces costs, and improves assembly efficiency, which is conducive to improving the competitiveness of industrial control products.
