Based on this, the sum of the lengths of the first side groove 13 and the second side groove 23 is greater than the length of the first card groove 120.

Since the longer the groove length is, the larger the required draft angle is, and the larger the machining error is, the accuracy of the fitting of the upper ridge 321 (lower ridge 322) of the side plate 3 with the first side groove 13 and the second side groove 23 is easily affected when the housing is injection molded. If the length of the first side groove 13 is much longer than the length of the second side groove 23 or the entire side plate 3 is mounted on the first housing 1, at this time, the center of gravity of the mounting of the side plate 3 is mainly on the first housing 1, and under the influence of the draft angle and the machining error of the first side groove 13, the upper protruding strip 321 (lower protruding strip 322) of the side plate 3 is easily loosely matched with the notch portion of the first side groove 13, and the mounting of the side plate 3 is unstable and easy to shake; however, the upper ridge 321 (lower ridge 322) of the side plate 3 is too tightly engaged with the root of the first side groove 13 to facilitate disassembly, and even the upper ridge 321 (lower ridge 322) of the side plate 3 may not be inserted into the root of the first side groove 13.

Therefore, in order to achieve both of the convenience of installation and stability of the side plate 3, the difference between the length of the first side groove 13 and the length of the second side groove 23 cannot be excessively large, and specific values may be designed according to specific cases. Preferably, the length of the first side groove 13 is the same as the length of the second side groove 23, so that the die opening and die drawing of the first shell 1 and the second shell 2 can be conducted to die drawing towards two ends in the middle, the gap errors of the groove root parts and the groove mouth parts of the first side groove 13 and the second side groove 23 are smaller, the problems that the side plates 3 are unstable in installation of the groove mouth parts and too tight in installation of the groove root parts caused by die drawing are greatly reduced, and meanwhile the processing difficulty of the first shell 1 and the second shell 2 can be reduced. Of course, in other embodiments, the length of the first side slot 13 and the length of the second side slot 23 may be different, so long as the side plate 3 is ensured to be stably mounted, which is not illustrated here.

In order to facilitate the alignment and insertion of the upper protruding strip 312 (lower protruding strip 322) of the side plate 3 with the first side groove 13 of the first housing 1 and the second side groove 23 of the second housing 2, both ends in the longitudinal direction of the upper protruding strip 321 (lower protruding strip 322) of the side plate 3 are subjected to the C-angle treatment. In addition, the upper raised strips 321 (lower raised strips 322) of the side plates 3 are subjected to C-angle treatment, so that the alignment problem caused by machining errors can be eliminated, and the side plates are convenient to assemble in place.
