Description

Technical Field

[0001] The utility model relates to the field of high-strength plastic casings, and particularly relates to a high-strength plastic casing. Background Technique

[0002] The plastic casing is an important part of the terminal wire, providing a stable installation position for the terminal, ensuring that the terminals are neatly arranged, not easily loosened, effectively preventing current leakage, ensuring the safe operation of the electrical system, being able to resist the erosion of various chemical substances, remaining stable in different environments, having a certain compressive and impact resistance ability, and protecting the internal terminals.

[0003] The existing plastic casings have weak compressive ability. When facing strong external pressure, the casings are prone to deformation, resulting in the displacement of the terminals, thus affecting the stability of the electrical connection. At the same time, the connection parts of the existing plastic casing buckles may become loose and broken after long-term use due to fatigue, which may cause the connection between the terminal wire and the connector to become loose, and signal transmission instability may occur.

[0004] Therefore, the utility model provides a high-strength plastic casing to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and a high-strength plastic casing is proposed. The fixedly arranged reinforcing baffle and reinforcing ribs are made of iron material, which can provide stable support, improve the bearing capacity of the components and the ability to resist deformation, effectively resist the damage of external pressure to the internal terminals and circuits, extend the service life of the terminal wire, and even when under greater pressure, can keep the position of the terminals accurate and stable. By pressing down the fixing plate, it presses multiple rubber blocks. At this time, the rubber blocks store elastic potential energy. After the fixing plate moves to the specified position, the elastic potential energy of the rubber blocks is released to bounce up the fixing plate, and it is clamped with the connector by using the first clamping block, thus avoiding the situation of loosening and breaking after long-term use at the connection, ensuring the firm connection between the terminal wire and the connector, and effectively avoiding poor contact or connection interruption caused by the breakage of the buckle.

[0012] Through the above technical solution, the rubber blocks are convenient for bouncing up the fixing plate after being pressed. At the same time, the first slots opened on the inner sides enable the rubber blocks to increase elasticity by using air after being pressed.

[0013] Further, fiberglass layers are fixedly arranged on the outer sides of the main body, the plug-in column and the base, and a flame retardant is fixedly arranged on the outer sides of the plurality of fiberglass layers;

[0014] Through the above technical solution, the fiberglass layer can significantly enhance the strength and rigidity of the plastic shell, improve the tensile and bending resistance performance, and the flame retardant improves the flame retardant performance of the plastic shell and enhances the use safety, especially in high-temperature or flammable environments.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Referring to Figures 1-4 , an embodiment provided by the present invention: a high-strength plastic housing, including a main body 2, a plurality of plug-in columns 1 are fixedly arranged at one end of the main body 2, a base 3 is fixedly arranged at the other end of the main body 2, a card slot 6 is opened inside one end of the base 3, glass fiber layers 8 are fixedly arranged on the outer sides of the main body 2, the plug-in columns 1 and the base 3, a flame retardant 7 is fixedly arranged on the outer sides of the plurality of glass fiber layers 8, a fourth slot 5 is opened inside the plurality of plug-in columns 1, and a plurality of third slots 4 are opened inside the main body 2.

[0032] The main body 2 facilitates the installation of more mechanisms of the device and plays a supporting role. The plug-in column 1 is a columnar structure for plug-in connection with other components. The base 3 plays a supporting role. The card slot 6 is set by being clamped with the second card block 207, so that the fixing plate 205 remains stable when moving. The glass fiber layer 8 can significantly enhance the strength and rigidity of the housing. The flame retardant 7 improves the flame retardant performance of the housing and enhances the use safety. The third slot 4 and the fourth slot 5 facilitate the installation of terminal wires.

[0033] Referring to Figures 2-3 , the main body 2 includes a housing 201 and a fixing plate 205. A second slot 210 is opened in the middle of one end of the housing 201. Reinforcing baffles 203 are fixedly arranged inside both ends of the housing 201. A plurality of reinforcing ribs 202 are fixedly arranged between the two reinforcing baffles 203. A plurality of rubber blocks 209 are fixedly arranged inside the second slot 210. A first slot 208 is opened inside the plurality of rubber blocks 209. One end of the plurality of rubber blocks 209 is fixedly arranged with one side of the fixing plate 205. A first card block 204 is fixedly arranged on the front side of the upper end of the fixing plate 205. A plurality of anti-slip blocks 206 are fixedly arranged on the front side of the middle end of the fixing plate 205. A second card block 207 is fixedly arranged on the lower side of the fixing plate 205. The outer side of the second card block 207 is clamped with the inner side of the card slot 6.

[0034] By pressing the fixed plate 205 to deform the rubber block 209 by pressing, and at the same time compressing the air inside the first slot 208. After moving the fixed plate 205 into the connector, the multiple rubber blocks 209 bounce up the fixed plate 205. The first slot 208 uses the compressed air to enhance the elastic force of the rubber block 209, so that the fixed plate 205 is clamped with the connector by using the first clamping block 204, thereby achieving fixation, avoiding the risk that the connection part of the existing buckle is easily broken after long-term use, reducing the risk of equipment failure caused by the damage of the buckle, and improving the stability of the whole system.

[0035] Working principle: When the device is in use, the terminal wire enters the fourth slot 5 through the third slot 4 for installation. The strengthening baffles 203 fixedly arranged at both ends provide stable support for this mechanism. The strengthening ribs 202 fixedly arranged further improve the compressive capacity of this mechanism and enhance the compressive strength of this mechanism; press the fixed plate 205 downward to deform the multiple rubber blocks 209 by pressing. By moving the fixed plate 205 into the connector and then releasing the fixed plate 205, the elastic potential energy stored in the multiple rubber blocks 209 is released to bounce up the fixed plate 205, so that it is clamped with the connector by using the first clamping block 204, thereby completing the installation and avoiding the situation that the connection part breaks after long-term use.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
