Terminal devices such as mobile phones, tablet computers, communication watches and the like have become essential scientific and technological products in the life, study and entertainment processes of people. Along with the diversified development of terminal equipment function, terminal equipment's a great variety, the brand is various for can supply the consumer to select terminal equipment also a lot, how to obtain consumer's favor, become the problem that terminal equipment producer more and more paid attention to.

At present, along with the development of terminal equipment, terminal equipment integrates more and more highly, and in order to adapt to the miniaturization simultaneously, the clearance between the inside electronic components of terminal equipment is littleer and more compact, and the overall arrangement is more and more compact.

In the related art, the terminal equipment needs to use a transmission line (e.g., a coaxial cable, etc.) to connect electronic components at different positions. The transmission line is typically disposed within a wire slot of the middle frame. Because the transmission line is not firmly fixed in the wire slot, the radiation performance of the weather device is negatively affected due to deviation or inconsistent installation in the batch production process of the transmission line. Therefore, the conventional method is to arrange the metal middle frame on the middle frame, so that a shielding wall can be formed by utilizing the metal side wall of the wire slot, and negative influences on the radiation performance of the weather device caused by inconsistent installation of the transmission line or infirm installation of the transmission line are reduced or avoided. However, this increases the difficulty of manufacturing the middle frame, which is not favorable for reducing the cost of the terminal device.

Accordingly, there is a need for an intermediate frame and a housing assembly that can reliably mount a transmission line, that can be easily manufactured, and that can reduce the cost of a terminal device.

For a better understanding of the middle frame and housing assembly of the present disclosure, the following description is set forth in connection with the terminal device of the present application.

As shown in fig. 1 to 3, in an embodiment of the present disclosure, there is provided a terminal device 10 including a case assembly 10a, a transmission line 10b, and an antenna device 10 c. The housing assembly 10a includes a middle frame 100 and a plastic member 200.

As shown in fig. 3 to 6, the middle frame 100 includes a first side portion 110, and the first side portion 110 includes a limiting surface 111, a limiting protrusion 112, and a bearing surface 113 configured to bear the transmission line 10 b. The limiting surface 111 and the limiting convex body 112 are oppositely arranged at intervals on two sides of the pressure-bearing surface 113 and form mounting grooves 114. The first side portion 110 further includes a notch 115 disposed opposite to the limiting surface 111, and the notch 115 and the limiting protrusion 112 are disposed outward relative to the limiting surface 111. The plastic part 200 is fixedly disposed on the middle frame 100, and a portion of the plastic part 200 is disposed at the notch 115 and spaced from the limiting surface 111 to form a first accommodating groove 210 for accommodating the transmission line 10 b. The transmission line 10b is disposed on the pressure-bearing surface 113, and the transmission line 10b is inserted into the mounting groove 114. At least a portion of the antenna device 10c is disposed outside the plastic part 200 and covers the position-limiting protrusion 112.

At this time, the transmission line 10b most easily affecting the antenna device 10c is fixed by the limiting surface 111 and the limiting convex body 112, so that the transmission line 10b of the portion is firmly fixed, and the radiation performance of the antenna device 10c is not affected by the inconsistent installation of the portion of the transmission line 10 b. In addition, by providing the notch 115, the manufacturing difficulty can be reduced, so that the middle frame 100 can be manufactured by integral molding, the processing steps can be reduced, the manufacturing cost of the middle frame 100 can be reduced, the manufacturing difficulty of the housing assembly 10a can be reduced, and the cost of the terminal device 10 can be reduced.

It can be understood that the transmission line 10b in the coverage area of the antenna device 10c has the largest influence on the antenna device 10c, and the transmission line 10b is limited and fixed by the limiting surface 111 and the mounting groove 114 formed by the limiting convex body 112. When the transmission line 10b is installed, only the transmission line needs to be pressed into the installation groove 114 and is in contact with the pressure-bearing surface 113, so that the transmission line 10b cannot easily deviate, the transmission line 10b is firmly fixed, the installation consistency of the transmission line 10b in the batch production process can be ensured, and the negative influence on the radiation performance of weather devices is avoided.

In addition, the transmission line 10b is firmly fixed, and the first receiving groove 210 is used for limiting.

Furthermore, the plastic member 200 is used to cooperate with the middle frame 100, so as to further reduce the difficulty of manufacturing the middle frame 100. Meanwhile, the plastic member 200 is disposed between the middle frame 100 and the antenna device 10c such that they are disposed in an insulated manner. Moreover, the transmission line 10b is reliably mounted, so that the antenna device 10c is not adversely affected, the distance between the transmission line 10b and the antenna device 10c is further reduced, the space utilization rate of the terminal device 10 is improved, and further the terminal device 10 can be miniaturized, or more functional devices can be integrated, or the performance of a certain functional device can be improved. This can improve the product competitiveness of the terminal device 10.

Thus, the antenna device 10c is conveniently installed by using the rear cover 300, and the distance between the radiation layer and the transmission line 10b is greater than or equal to 1mm, so that the interference of the transmission line 10b on the radiation performance of the antenna device 10c can be effectively avoided.

Thus, the transmission line 10b can be further extruded and fixed by the extrusion body 220 on the plastic part 200, so that the transmission line 10b is firmly fixed on the pressure-bearing surface 113, and the installation consistency is good.

It should be noted that the number and length of the pressing bodies 220 can be selected according to actual needs. In some embodiments, at least four extrusion bodies 220 are disposed on the plastic part 200 along the length direction of the pressure-bearing surface 113 to extrude and fix the transmission line 10b, so as to ensure that the transmission line 10b can be reliably fixed in the first receiving groove 210 without easily shifting, and ensure the stability of the radiation performance of the antenna device 10 c.
