Description

Technical Field

[0001] The utility model relates to a power supply detection box shell. Background Art

[0002] The power detector is mainly used to detect the positive and negative polarity of the power supply to prevent circuit failure or damage caused by miswiring or wrong polarity. Its working principle is mainly based on the unidirectional conductivity of the diode, the conductivity principle of the conductive material, and the electrical principle and charge properties of the dielectric.

[0003] The housing used by the power detector is usually rectangular and is made by injection molding. Figure 2 In the structure of the shell 1 shown, the socket part for plugging in electronic components is generally arranged non-center-symmetrically on the inner wall surface of the shell 1, and no components are installed on the left and right sides of the center of the inner wall of the shell 1. Therefore, under conventional thinking, the injection port is arranged in the width direction of the shell 1, and in order to improve the shell strength and prevent deformation, some reinforcing ribs 9 are arranged on the inner wall surface of the shell 1 on both sides of the socket 2. However, when the shell 1 with such a structure is injected, the molten material flowing in from the injection port flows from left to right along the length direction of the shell 1, which will be blocked by the reinforcing ribs 9, resulting in an uneven injection layer; at the same time, the stress generated by the reinforcing ribs 9 during the injection molding process is likely to cause a concave phenomenon on the surface of the shell 1. Summary of the invention

[0004] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, the utility model provides a power supply detection box housing which can ensure uniform injection molding and improve injection molding flatness.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a power supply detection box shell, which has a rectangular shell, and a socket is arranged on the shell, and the socket divides the inner wall surface of the shell into a left area and a right area, and the left area and the right area are both smooth and flat, and the injection molding injection port is arranged along the long side of the shell and corresponds to the left area and the right area respectively.

[0006] The socket includes a device socket parallel to the width direction of the shell, a rectangular socket is connected to the lower part of the device socket, and a wiring socket is provided on the inner wall of the shell parallel to the length direction of the shell. The device socket is arranged on the right side of the center of the shell, and the wiring socket is located at the bottom of the left area.

[0007] A right-angle rib is connected between the rectangular socket and the wiring socket.

[0008] The beneficial effects of the utility model are as follows: during injection molding of the utility model, the molten material flows from top to bottom along the width direction of the shell into the left area and the right area. Since the left area and the right area formed by the inner wall of the shell separated by the connector are smooth planes, the molten material will not be affected by resistance during the flow process, and the molten material has good uniformity. At the same time, the reinforcing ribs are removed from the left area and the right area, and the shell surface will not be concave due to stress during the molding process, thereby improving the shell quality.

[0013] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0014] like Figure 1 The power detection box shell shown has a rectangular shell 1, on which a socket 2 is provided. The inner and outer ends of the socket 2 protrude respectively inside and outside the rectangular plane of the shell 1, and the inner part of the socket 2 divides the inner wall plane of the shell 1 into a left area 3 and a right area 4.

[0015] Specifically, the socket 2 includes a device socket 5, a rectangular socket 6 and a wiring socket 7, wherein the device socket 5 is parallel to the width direction of the housing 1 and is arranged to the right relative to the center of the housing 1, the upper end of the device socket 5 is connected to the upper side wall of the inner wall plane of the housing, the rectangular socket 6 is connected to the lower end of the device socket 5, and the wiring socket 7 is located at the bottom of the left area 3 and is arranged parallel to the length direction of the housing 1. A right-angle rib 8 is connected between the rectangular socket 6 and the wiring socket 7.

[0016] The left area 3 is surrounded by the left side wall of the shell 1, the upper side wall of the shell 1, the device socket 5, the right-angled rib 8 and the rectangular socket 6, and the right area 4 is surrounded by the right side wall of the shell 1, the upper side wall of the shell, the lower side wall of the shell, the device socket 5, and the right-angled rib 8. The left area 3 and the right area 4 are both smooth and planar.

[0017] During injection molding, two injection ports are set along the long side of the shell 1, and each injection port corresponds to the left area 3 and the right area 4 respectively. In this way, during injection molding, the molten material enters the left area 3 and the right area 4 from the injection port, and flows from top to bottom along the width direction of the shell 1. Since the left area 3 and the right area 4 are both smooth planes, the molten material will not be affected by resistance during the flow process, so that the formed injection layer has good uniformity. At the same time, since there are no reinforcing ribs 9 set in the left area 3 and the right area 4, the stress generated by the presence of the reinforcing ribs 9 during the molding process will not cause the surface of the shell 1 to be concave, thereby improving the quality of the shell 1.

[0018] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
