Description

Technical Field

[0001] The utility model relates to the technical field of wiring plugs, in particular to a wiring plug and a male plug and a female plug which are resistant to pulling and falling off. Background Art

[0002] Common wiring plugs on the market, such as the attached Figures 10-11 The DC plug has a loose inner snap-on structure, which is easy to loosen and fall off after multiple up and down swings, and even causes a short circuit in the conductor. The existing inner snap-on structure is unreliable in connection and has poor tensile and anti-detachment performance. Utility Model Content

[0003] The main purpose of the utility model is to provide a wiring plug that is resistant to pulling and anti-detaching. By improving the structure of the wiring plug, a wiring plug with reliable connection and resistant to pulling and anti-detaching is obtained, so as to overcome the technical problems in the prior art that the buckle structure inside the wiring plug is loose and unreliable and the resistant to pulling and anti-detaching performance is poor.

[0004] To achieve the above objectives, the utility model provides a tensile and anti-detachment wiring plug, comprising an inner frame and an electric wire, wherein the electric wire comprises a terminal, and the inner frame comprises a connecting end, an inner frame middle portion, and an inner frame tail portion.

[0005] A through hole is provided in the middle of the inner frame, so that the electric wire can pass through the inner frame along the through hole and the terminal is fixed to the connection end.

[0006] The tail of the inner frame includes an inner frame outer wall, a threading inner column and a plurality of ribs connecting the threading inner column and the inner frame outer wall. The threading inner column is arranged around the through-hole. The inner frame outer wall, the threading inner column and two adjacent ribs are combined to form a groove. The rib is provided with an anti-detachment through hole so that the two adjacent grooves can be connected and form an embracing groove around the threading inner column.

[0007] It also includes a net tail formed by injection molding at the tail of the inner frame through the known injection molding technology. The net tail has a net tail column corresponding to the groove and a net tail column connection position corresponding to the anti-detachment through hole. The net tail is connected to the inner frame through the embracing groove and fixes the wires to form a tensile and anti-detachment wiring plug.

[0008] In the utility model, a rib position is provided at the tail of the inner frame, so that the threading inner column is connected to the outer wall of the inner frame, which can prevent the outer wall of the inner frame from being compressed and deformed under pressure when the mesh tail is injection molded; an anti-detachment through hole is provided at the rib position, so that when the mesh tail is injection molded, the injected glue is connected through the anti-detachment through hole to form a mesh tail that structurally embraces the threading inner column, and forms a tight contact connection under the injection pressure, which plays a role in resisting tension and preventing detachment. The utility model not only maintains reliable fixation through a simple and compact structure, but also the embracing design makes the mesh tail tightly connected to the inner frame, reducing the risk of poor contact caused by the connection plug buckle or connection failure in the prior art.

[0009] At the same time, when the net tail is injection molded with a different color or material from the inner frame, the appearance of the net tail and the inner frame can be designed according to different needs to form a novel decorative effect.

[0010] Preferably, a groove is provided on the inner wall surface of the threading inner column to prevent dislocation, an inner convex portion is formed inwardly on the side of the net tail column to be embedded in the groove to prevent dislocation, a curved groove is provided on the outer wall of the inner frame to communicate with the groove, and a curved convex portion is formed outwardly on the side of the net tail column to be embedded in the curved groove.

[0011] Further preferably, the anti-dislocation groove is square.

[0012] Further preferably, grooves are provided on two opposite inner wall surfaces of the threading inner column to prevent dislocation.

[0013] After the mesh tail is formed by injection molding, the inner convex part of the mesh tail column formed by glue injection corresponding to the anti-slip groove forms an inverted buckle, which effectively enhances the longitudinal tensile resistance and anti-slip resistance. The curved convex part of the mesh tail column corresponding to the curved groove enhances the lateral tensile resistance, and the appearance allows the wiring plug to form a curved color separation, thereby improving the decorative effect.

[0014] Preferably, the ribs are evenly arranged at 3 to 8 positions, and the cross-section of the anti-slip through hole is a round hole or a square hole. Further preferably, the ribs are arranged at 4, 6 or 8 positions.

[0015] Preferably, the cross-section of the embracing groove is in the shape of an elliptical ring or a circular ring.

[0016] The utility model also provides a male plug, which adopts the anti-pulling and anti-detachment wiring plug in any of the above schemes, thereby having all the corresponding beneficial effects of any of the above schemes, which will not be described in detail here.

[0017] Preferably, the electric wire comprises an electric wire segment and a connecting segment, the connecting segment comprises a terminal and a protruding positioning portion connected to the terminal, and the through-holes are arranged in a sequence from the connecting end portion to the rear end of the inner frame, including terminal holes matching the size of the terminal, positioning portion interference holes, and electric wire segment holes that can pass through the electric wire segment, wherein the hole cross-sectional area S 端子孔位 <S 定位部干涉孔位 ≤S 电线段孔位 The protruding positioning portion is matched and clamped in the interference hole of the positioning portion.

[0018] In this solution, the terminal matches the size of the terminal hole, the protruding positioning part matches the interference hole of the positioning part and is clamped to prevent the wire from retreating. At the same time, the protruding positioning part cannot pass over the terminal hole. The protruding positioning part forms a fixed point, which is convenient for quickly confirming that the terminal is in place when preparing the wiring plug. When the protruding positioning part is clamped in the interference hole of the positioning part in the through hole and cannot move forward, it can be confirmed that the terminal has been positioned in the terminal hole.

[0019] Further preferably, the terminal is a copper nail terminal, the protruding positioning part is the ear buckle of the copper nail terminal, and the copper nail terminal is riveted to the wire section. Here, for the terminal corresponding to the male plug or the female plug, other well-known terminals can also be used, and other well-known protruding positioning parts can also be used for the protruding positioning part. On the premise that the terminal itself is designed with a positioning function, the protruding positioning part can also be omitted. For example, when the terminal is a flat head terminal and the corresponding terminal hole is set as a flat hole with a size matching it, the protruding positioning part and the terminal are combined into one, and the corresponding positioning part interference hole and the wire section hole are combined into one.

[0020] The present utility model also provides a female plug for cooperating with the male plug in any of the foregoing solutions. The female plug adopts the tensile and anti-disconnection wiring plug in any of the foregoing solutions, and thus has all the beneficial effects corresponding to any of the foregoing solutions, which will not be elaborated here.

[0021] Preferably, the female plug is provided with a snap connection position or an elastic snap, and the male plug is provided with an elastic snap corresponding to the snap connection position or a snap connection position corresponding to the elastic snap.

The male plug and the female plug can also adopt other well-known snap connection methods.

[0023] Compared with the prior art, in the present utility model, a groove is formed by enclosing the outer wall of the inner frame, the wire threading inner column and two adjacent rib positions at the tail of the inner frame.
