Description

  The present invention relates to a type of waterproof and reinforced insulation terminal, and more particularly to a type of accident prevention design that prevents liquid from penetrating into the plug during use of the insulation terminal and causes an electric wire ignition accident.

  In general, in daily life and industrial operation, use of electric appliances or electric tools, the power source of AC electricity is connected to an electric plug and an outlet, and current is sent to the electric appliance or electric tools. The place where the plug is used is very wide, and it is necessary to use the plug because there are electrical equipment even in a humid environment. As a result, wet water molecules often penetrate into the outer edge of the terminal body and the insertion hole of the plug case. For this reason, the use of plugs is often related to the safety of the equipment being operated or the system being operated. May form a serious industrial safety or environmental protection problem.

Therefore, prevention of water penetration is an important research subject of the plug, and a well-known designer has submitted an insulated terminal 1 as shown in FIG. The protective sleeve 12 is installed on the outer edge of the terminal body 11, the protective sleeve 12 is formed with a hollow portion 121 in the middle, and the hollow portion 121 is formed in a shape corresponding to the terminal main body 11. Although the protective sleeve 12 is inserted, this protective sleeve 12 has the following basic problems.
1. Such a protective sleeve belongs to an additional part, and the connection between the protective sleeve and the terminal body is in an additional fitting state. Therefore, the production cost is high, and it is necessary to form the protective sleeve separately by forming a mold.
2. Such a protective sleeve is an additional part, which is basically a two-piece separable from the terminal body, has poor adhesion, lacks positioning, i.e. it can slip off, and it is combined with the terminal body. After that, during the pressure forming operation process in the subsequent process, it is easy to fall off, resulting in poor production or a defective product rate.

  An object of the present invention is to provide a waterproof and reinforced insulation terminal. By the design of the present invention, the plug can prevent moisture from penetrating and enhance safety.

  The technical means used by the present invention to solve the problems of the prior art is to design a waterproof reinforced insulated terminal, in which one stage of the terminal body is covered with an insulating layer, and this stage is defined as a subsequent stage. And the exposed step not covered with the insulating layer is defined as the previous step. Further, a perforation is provided in the rear stage of the terminal body, the plastic material before drying and solidification of the insulating layer is filled in the perforation in the rear stage of the terminal body, and the surface of the rear stage of the terminal body is covered to form a strong bond after the drying and solidification. Particularly in the present invention, at least two spaced apart first ribs and second ribs are formed in the insulating layer corresponding to the rear stage of the terminal body, and at least one recessed neck groove is formed between the first ribs and the second ribs. A bent path for preventing penetration of moisture from the outside is provided at the outer edges of the first rib, the second rib, and the neck groove, and the safety effect of preventing penetration of moisture from the outside is achieved. .

According to the first aspect of the present invention, one stage of the terminal body is covered with an insulating layer, this stage is defined as a rear stage, an exposed stage not covered with an insulating layer is defined as a front stage, and a pressure line stage is provided behind the rear stage. Waterproof, reinforced insulation that is stretched and provided with perforations in the latter part of the terminal body, and the plastic material is filled in the perforations in the latter part of the terminal body, covers the surface of the latter part of the terminal body, and forms a stable bond after drying and solidification At the terminal,
Corresponding to the latter stage of the terminal body in the insulating layer, at least two spaced apart first ribs and second ribs are formed, and at least one recessed neck groove is formed between the first ribs and the second ribs, A waterproof reinforcement-insulated terminal is characterized in that a bent path for preventing penetration of moisture from the outside is formed on the outer edges of the first rib, the second rib and the neck groove.

1. The insulating layer of the present invention has at least two spaced apart first and second ribs corresponding to the rear stage of the terminal body, and at least one recessed neck groove between the first and second ribs. A bent path is formed at the outer edge of the first rib, the second rib and the neck groove to prevent moisture from entering from the outside, and a close separation is formed using the overlap of the two convex edges. The safety effect of preventing water penetration has been achieved.
2. The present invention strongly retains the perforations after the plastic material is dried and solidified, and the insulating layer is integrally joined with the terminal body of the present invention in the form of a three-dimensional space, has good adhesion, and further prevents the penetration of water. Protection is formed.
3. Except for the design to prevent the penetration of water, the present invention also has an insulating layer required by the terminal body, so that the plug user can touch the rear part of the terminal body with fingers. Prevention safeguards are formed.

  In summary, the present invention has a practical effect and does not yet have a description or public use in a publication, and meets the requirements for registration of a utility model.

  Please refer to FIG. 3 in conjunction with FIG. The present invention provides a kind of waterproof and reinforced insulation terminal, and the insulation terminal 2 includes a terminal body 21 and an insulation layer 22.

  The terminal body 21 is made of a metal material and has conductive characteristics. As shown in FIG. 4, the terminal body 21 is defined by a front stage 211 and a rear stage 212 according to the covering degree of the insulating layer 22 described later, and a pressure line stage 213 extends from the rear stage 212 to the rear to crimp the electric wire. And served for pinching. That is, the step portion covered with the insulating layer 22 is defined as the rear step 212, and the exposed metal step not covered with the insulating layer 22 is defined as the front step 211. Further, as shown in FIG. 2, a perforation 214 is provided in the rear stage of the terminal body 21.

  The insulating layer 22 is filled with the perforations 214 in the rear stage 212 of the terminal body 21 in a molten state, and the plastic material before drying and solidification is covered, and covers the surface of the rear stage 212 of the terminal body 21 and is stable with the terminal body 21 after drying and solidification. Form a bond. The plastic material holds the perforations 214 in a three-dimensional space form after drying and solidification, and this holding holds and bonds the terminal body 21 in an intrusive manner, and does not escape unless the insulating layer 22 is torn, providing a safe and strong bond Form.

  The main features of the present invention are as follows. At least two spaced apart first ribs 221 and second ribs 222 are formed corresponding to the rear stage 212 of the terminal body 21 of the insulating layer 22, and at least one recessed neck is formed between the first ribs 221 and the second ribs 222. A groove 223 is formed, and a bending path is formed jointly on the outer edges of the first rib 221, the second rib 222, and the neck groove 223.

  As shown in FIGS. 5 and 6, the present invention can be applied to the first type two-pole plug 3 and the second type three-pole plug 4.

  The foregoing is a preferred embodiment of the present invention in the industry, and any changes that bring about the same effects that can be made based on the scope of the claims of the present invention are within the scope of the present invention.
