Description

A new type of plug-in module

technical field

The utility model relates to an auxiliary electrical appliance for low-voltage switchgear and control equipment, in particular to a plug-in module for wiring drawer cabinets and a plug-in module in the field of power supply and distribution.

Background technique

The plug-in module is mainly used for circuit connection between a kind of drawer-type power equipment and various electronic instruments and electrical equipment. In some drawer-type electrical boxes, there are usually high-voltage, high-current connection lines, and there are plug-in modules for multi-strand lines. In order to avoid accidents after the high-voltage or high-current wiring is turned on due to some kind of error, before the plug-in module of each line is turned on, it is necessary to continuously check the line for low voltage and low current, and feed back the detection signal; the drawer cabinet Each plug-in module of the type electrical box must ensure good contact and high reliability when it is turned on. Therefore, a plug-in module that continuously and stably outputs detection signals during the conduction process of the plug-in modules on the moving panel of the drawer cabinet is needed.

In actual use, the combination length of the plug-in module is diverse, and there are many length specifications. The direct interference fit combination of the tie rod is not used. Although the tie rod parts are omitted, the actual application effect is not good, especially the entire plug-in module. The ability to withstand torsion is extremely poor; another combination technology is to directly inject multiple terminal blocks into a whole. This structure reduces the flexibility of the product in terms of length adaptation. Different length specifications require different molding molds. The number of molds is greatly increased, which not only prolongs the production cycle, but also increases the manufacturing cost.

The existing plug-in modules on the moving panel of the drawer cabinet mostly use hard plugging. Due to manufacturing and installation errors, the plug-in modules are not aligned before plugging in and out, and they are forced to plug in and out under the guidance of the guide mechanism. During the process, the guiding mechanism, the socket, and the contact pin work under the condition of bearing additional load, so it is not easy to ensure their contact reliability; the guiding mechanism and the fixing mechanism are independent, which makes the size of the space wasteful, and it is not easy to realize the miniaturization of the plug-in module; at the same time , When the guide mechanism adopts metal parts, it is not conducive to the realization of electrical safety.

In order to solve the above problems, the technical solution adopted in the utility model is:

The utility model discloses a novel plug-in module, which comprises a movable end and a fixed end. The movable end includes a movable end cover, a movable terminal block, a guide column, a pull rod, and a mounting plate 1; The crimping screw is installed in the screw hole of the crimping frame, and the crimping frame is arranged in the independent installation groove of the plug insulator. The pull rod is connected with the end covers at both ends to connect the movable terminal block in series and tighten it. The end conductive piece passes through the crimping frame and is fixed in the pin limit groove of the plug insulator. The guide column is arranged on the movable end cover on both sides. The guide column with screw insert installs the entire movable end on the movable panel and realizes Floating: The movable end adopts a floating mechanism, which automatically adapts to the alignment position with the static end during the plugging process, and does not bear additional load.

The fixed end includes a fixed end terminal block, a fixed end cover, a pull rod, and a mounting plate 2 . The terminal block at the fixed end: an insulator at the fixed end, a crimping frame, a crimping screw, and a conductive sheet at the fixed end.

That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

Embodiment: a plug-in module, including a movable end (001) and a fixed end (002).

As shown in Figure 1, there is a one-to-one correspondence between the movable end (001) and the fixed end (002) in terms of quantity and arrangement, and the plugging action can be completed. When the movable end (001) is inserted into the fixed end (002), the guide column (101) arranged on the movable end (001) is inserted into the guide hole of the fixed end cover (203) arranged on the fixed end (002) for positioning ; When the guide column (105) on the movable end cover (106) of the movable end (001) enters the guide hole of the fixed end cover (103) on the fixed end (002), under the action of the floating mechanism of the movable end (001), , the movable end (001) automatically adjusts its position to adapt to the alignment with the fixed end (002), ensuring that the movable end conductive sheet (104) arranged on the movable end (001) and the fixed end conductive sheet arranged on the fixed end (002) (202) contact conduction, while ensuring that the movable end (001) and the fixed end (002) are always in the centered state, and the movable end conductive sheet (104) and the fixed end conductive sheet (202) are always in a reliable contact conduction state, automatically Adjust the position to ensure that the plug-in module does not bear additional load, and the current loop that realizes the conduction of the electrical drawer cabinet can reliably transmit the detection signal.

As shown in Figure 2, the floating mechanism of the movable end (001) is mainly composed of the movable end cover (106), the guide column (105), and the mounting plate 1 (107). The insert nut inside the boss of the movable end cover (106) is connected and fixed; the height of the boss of the movable end cover (106) is greater than the thickness of the mounting plate 1 (107), and the opening of the mounting plate 1 (107) is larger than that of the movable end cover ( 106) The diameter of the boss, so that the floating position of the movable end (001) can automatically adapt to the insertion and removal requirements without additional load.

As shown in Figure 3, the movable end (001) is composed of a plurality of movable terminal blocks (011) selected according to needs and two movable end covers (106) with mutual interference fastening, and they are connected by a pull rod (108). String them together, and then tighten the tie rod (108) so that the thread at the other end is connected to the insert nut on the movable end cover (106); It can flexibly realize the combination of any length movable terminal block (011), which is convenient to use.

The connection method of the fixed end (002) is consistent with that of the movable end (001), so it will not be repeated.

The fixed end insulator (201) is provided with a fixed end cover (203), which is structurally equipped with guide holes and insert nuts, and is fixed on the mounting plate 2 (204) by screws.
