Problems solved by technology

[0003] The inner frame formed by this kind of terminal cooperates with the inner frame body often causes the terminal and the inner frame body to loosen each other (circumferential looseness, unable to meet the torsional force requirements of safety regulations), displacement (that is, the terminal becomes loose and retreats), However, in the process of forming the plug housing inside the mold of the plug housing through integral injection molding, since the injection molding is carried out under the conditions of high temperature and high pressure, the yield rate of the finished plug product is often poor, and Affects the exposed length of the terminal, which does not meet the requirements of safety regulations

Embodiment Construction

[0024] see figure 1 , figure 2 , image 3 The structure of a combined plug inner frame 1 shown in the present invention mainly includes:

[0025] Two terminals 11, see Figure 4 , Figure 5 and Image 6 As shown, each terminal 11 itself is considered as a section, and the front section 111 can be a cylindrical pin with a circular arc shape at the front end. The rear part of the terminal 11 is provided with a wire slot 114 as a riveting part, which is used for joining with the power wire to achieve the purpose of conduction.

[0026] The terminal 11 is provided with a cover 112 at the rear end of the front section 111 to prevent the molten plastic material from overflowing from the body of the terminal 11 into the hollow part of the front section 111 during the injection molding filling process.

[0027] Each terminal 11 is provided with a frame edge 113 at a section thereof. The outer contour shape of the frame edge 113 can be generalized as a "D" shape, a rectangle, a...

Abstract

Present invention discloses a combined type plug interior framework structure, said interior framework main body including one interior framework basic body and at least two terminals, said interior framework basic body set with punch hole for at least two terminals. Present invention sets one architrave on one section of each terminal, punch hole edge set with a sash corresponded with terminal architrave for restricting reveal length of terminal in interior framework basic body, having positioning and steady property.

Description

technical field [0001] The invention relates to a structure of a combined plug inner frame, in particular to an inner frame body and an inner frame provided with at least two terminals. Background technique [0002] In general daily life and industrial operation, the use of electrical appliances or electrical appliances, the power source of the alternating current is mainly connected by a wire plug and a socket, and conducts current to the electrical appliances or electrical appliances. Generally, the operation method of plug injection molding is to put the terminal into an inner frame body after the crimping operation is completed, and then put it into the mold of the plug shell for integral injection molding. Therefore, the shortcoming of prior art is: [0003] The inner frame formed by this kind of terminal cooperates with the inner frame body often causes the terminal and the inner frame body to loosen each other (circumferential looseness, unable to meet the torsional ...
