Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, it should be understood that the orientation or positional relationship indicated with respect to the orientation description, such as up, down, front, rear, left, right, etc., is based on the orientation or positional relationship shown in the drawings, and is only for convenience of description and simplification of description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.

Referring to fig. 1 to 4, the power plug terminal fixing frame includes a frame body 100 and a positioning protrusion 200, the frame body 100 is hollowed to have a limiting through hole 300, the limiting through hole 300 is matched with the terminal 400 and used for limiting the offset of the terminal 400, for example, the limiting through hole 300 is circular, the size of the limiting through hole 300 is slightly larger than that of the terminal 400, so that the limiting through hole 300 is in clearance fit with the terminal 400, the frame body 100 can be just inserted into the terminal 400 and is not easy to slide out, and the positioning protrusion 200 is disposed on the upper end surface of the frame body 100 and is integrally formed with the frame body 100. It should be emphasized that the limiting through hole 300 is not limited to the circular shape, and for example, the limiting through hole 300 having a specific shape can be applied to various types of terminals 400, and any structure that can limit the movement of the terminal 400 is within the scope of the present invention.

In a further embodiment of the present invention, the frame body 100 is flat and massive, so that the material can be saved more by using the structure on the premise of ensuring the best fixing effect, and the frame body 100 is lighter and more beautiful. In addition, the end surface area of the frame body 100 is not larger than that of the plug, and the structure can save space and is convenient to store and package.

In a further embodiment of the present invention, the positioning protrusions 200 are perpendicular to the upper end surface, so as to ensure that the frame body 100 is uniformly stressed.

In a further embodiment of the present invention, the number of the positioning protrusions 200 is two, and is uniformly distributed between the limiting through holes 300. Compare and only have a location protrudingly 200, set up two and can further strengthen fixed effect, prevent that support body 100 from appearing crooked, guarantee that support body 100 atress is balanced.

In a further embodiment of the present invention, the positioning protrusion 200 is a long trapezoidal cone, and the cross-sectional area of the root of the positioning protrusion 200 is larger than the end surface area of the top thereof. The elongated trapezoidal pyramid structure can save material and increase the stress strength of the positioning protrusion 200.

It should be noted that if the positioning protrusion 200 is too short, the fixing effect is not good enough, and the length of the positioning protrusion 200 should be flexibly adjusted according to the length of the terminal 400 extending out of the plug, so as to ensure that the best use effect is achieved with the least material.

The working principle is as follows: after the plug finishes injecting plastics, plastics cooling shrinkage produces the internal stress, make the terminal 400 of burying in the plug atress take place the skew, and then make the terminal 400 that stretches out the plug outside produce the motion trend of outwards expanding or inwards gathering together, after the plug breaks away from the mould immediately with the mount cover in terminal 400, impel towards the plug terminal surface direction, until the location is protruding 200 and withstand the plug terminal surface, accomplish the axial positioning of support body 100, refer to fig. 4, spacing through-hole 300 provides the power opposite with above-mentioned motion trend so that terminal 400 keeps original position at this moment, offset the motion trend, keep the interval and the straightness that hangs down of terminal 400, reach the effect of fixed terminal 400.
