Description

Group vertical female insert frame structure

technical field

The invention of the utility model relates to the structure of the inner frame of the plug, in particular to a structure of the inner frame of the vertical female plug.

Background technique

Generally, the current for daily use and industrial use is mainly received and transmitted by wires and plugs, so the power supply is mainly from the supply end (socket) and the receiving end (plug), and if the sockets at the supply end are fixed on the wall or at a fixed position , it is inconvenient for the plug with limited wire length.

Therefore, the designer has extended the power supply of the plug into a so-called "extension socket" (referred to as a female plug in the industry) to supply the plug to conduct electricity, thus becoming an extension of the socket. And the general extension cord socket is mainly provided with a frame body first, and the front surface of the frame body is provided with several front perforations for the insertion of conductive terminals of electrical appliances; Wire) setting; while the front and rear perforations are interlinked to form a channel to provide the female plug terminal and the conductive terminal to form mutual contact and conduction to provide extended conduction.

Due to the current safety regulations in various countries, the female plug terminals are not allowed to be exposed due to restrictions. Therefore, in order to comply with the aforementioned safety regulations, some female plug terminals will be added on the end surface of the frame body (the direction facing the riveting line of the terminal is set as the end) There is a plastic insulating sleeve to surround the female terminal and prevent it from being exposed. However, this type of external insulating sleeve is time-consuming and costly.

Contents of the invention

Since the previous technology of the above-mentioned external insulating sleeve type is not ideal, and the designer of the utility model thinks that it is still advisable to be able to submerge the riveting wire section of the female plug terminal into the frame body, but due to the modern division of work, the female plug terminal Preliminarily combined with the frame body and then sent to the downstream manufacturer for riveting. At this stage, the female plug terminal must be initially combined with the frame body without loosening, but it cannot be excessively combined (for example, the inner frame is completely prepared, but the The riveting line section is submerged in the frame body so that the subsequent downstream manufacturers cannot rivet the line), so a structural design that takes into account and has the best of both worlds must be designed.

For this reason, the designer of the utility model designs a vertical female plug inner frame structure, including: three female plug terminals: each female plug terminal sequentially includes a plug-in section, a middle section and a riveting line section from front to back, The insertion-receiving section forms a tapered extension from the middle section so that the intersection of the insertion-receiving section and the middle section forms a relatively wide portion in outer diameter, and the upper outer edge of the middle section forms a groove edge; a frame , the frame body is provided with three holes for the insertion of the three female terminals; the inner edge of each hole is provided with a rib that can be elastically incorporated into the material of the groove edge; so that when the riveting section of the female terminal is exposed, the The rib body slightly blocks the relatively wide part, so that the female plug terminal can maintain the state where the riveting wire section of the female plug terminal is exposed, and when the external force is forced, the riveting wire section of the female plug terminal is submerged in the frame body, and the groove edge is elastically incorporated by the matching material of the rib body.

Each of the female socket terminals radially extends two spaced apart fins from the top of the middle section, and each hole of the frame body extends with two secondary holes for leading the two fins into.

In this way, the female socket terminal and the frame body can be initially combined at the upstream manufacturer so as not to be loose or excessively combined, which is not conducive to the subsequent riveting operation, and can facilitate the subsequent riveting operation of the downstream manufacturer quickly.

Detailed ways

The content, features and embodiments of the utility model creation are described below with drawings, so that your examiners can have a further understanding of the utility model creation.

Please refer to Fig. 1, and as shown in Fig. 2, the utility model is related to a structure of a vertical female insert inner frame, including:

Three female terminals 1A, 1B, 1C:

Each of the female plug terminals, taking the female plug terminal 1A as an example, as seen from Figure 5, includes a plug-in section 11, a middle section 12 and a riveting section 13 in sequence from front to back. The plug-in section 11 is provided with a front end. The opening 111 is used for other external conductive terminals to be inserted and connected, and the insertion-receiving section 11 is formed from the middle section to form a tapered extension so that the junction of the insertion-receiving section 11 and the middle section 12 forms a relatively narrow outer diameter. The wide portion 14 , and the upper outer edge of the middle section 12 forms a groove edge 15 .

A frame body 2:

The frame body 2 is provided with three holes 2A, 2B, and 2C: taking the hole 2A as an example, the hole 2A is used for the insertion of the three female terminals; 15 Ribs 21 incorporated into the elastic material;

As shown in FIG. 3 , when the riveting section 13 of the female plug terminal 1A is bare, the relatively wide portion 14 of the female plug terminal 1A is positioned because the rib body 21 makes the female plug terminal 1A slightly blocked, and therefore Due to the slight elastic force between the materials, the female terminal 1A can keep the rivet section 13 exposed. In this way, the receptacle terminal 1A and the frame body 2 can be preliminarily combined at an upstream manufacturer so as not to be loose or excessively combined to be unfavorable to subsequent riveting operations.

As shown in FIG. 4 , when forced by external force, it is usually mechanically forced in by the downstream manufacturer during the riveting process or the riveting is completed. The relatively wide part 14 of the female plug terminal 1A is forced to pass through the rib body 21, so that the The riveting section 13 of the female plug terminal 1A is submerged into the frame body 2 , and then the groove edge 15 is elastically incorporated by the rib body 21 with matching material. In this way, the combined positioning of the female terminal 1A and the frame body 2 can be completed.

As shown in FIG. 3 and FIG. 4 , the utility model creates a preferred embodiment, the female plug terminals 1A radially extend two spaced fins 16 on the top of the middle section 12 , and each of the frame body 2 Each of the holes 2A is extended with two secondary holes 22 through which the two fins 16 can be introduced, so that the downstream manufacturer can smoothly push the female terminals 1A into the frame body 2 for positioning after the riveting operation is completed.

The above description of the utility model is illustrative rather than restrictive. Those skilled in the art understand that many modifications, changes or equivalents can be made to it within the spirit and scope of the claims, but they will all fall into Within the protection scope of the present utility model.
