In some embodiments, the second bone strip 202 is centrally disposed with respect to the first bone strip 201.
For example, as shown in fig. 3, the second bone strip 202 is located at the midpoint of the first bone strip 201.
Wherein, the second bone strip 202 is arranged centrally with respect to the first bone strip 201, so that the first bone strip 201 and the second bone strip 202 are integrally formed into a symmetrical structure, so that the connection between the first shell 10 and the second shell 20 is more stable and the shearing resistance is stronger.
It should be noted that, the second bone strip 202 is not limited to be located at the middle position of the first bone strip 201, and left deviation or right deviation is satisfactory in a certain range, and those skilled in the art may set the second bone strip according to the actual situation, and the present utility model is not limited thereto.
In summary, in the case assembly 1000 provided by the embodiment of the utility model, the first dispensing slot 101 is formed on the first case 10 in the case assembly 1000, the second dispensing slot 102 is formed at the bottom of the first dispensing slot 101, and then the first bone strip 201 and the second bone strip 202 are formed on the second case 20 in the case assembly 1000 and covering the first case 10, the first bone strip 201 is inserted into the first dispensing slot 101, and the second bone strip 202 is inserted into the second dispensing slot 102, so that the second case is bonded with the first case. Because the at least two bone strips and the at least two glue dispensing grooves are connected in a matched mode, paths for external water vapor, dust and the like to enter the shell assembly are more complex, the shell assembly has better sealing effect, and components in the shell assembly can be better protected. In addition, since the first dispensing slot 101 and the second dispensing slot 102 are mutually communicated, the housing assembly 1000 of the present utility model can bond the first housing 10 and the second housing 20 with each other by dispensing only once, and the operation is simpler than two dispensing slots spaced apart from each other.
