Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-6, the utility model provides a wire-clamping fixed plug, which is mainly used for a double-pin plug, and the main structure of the whole plug comprises a shell 1, a wire body 2 and two pins 3, wherein the shell 1 is an insulating plastic shell, and can encapsulate and protect the internal structure. The two pins 3 are arranged on the same side of the shell and inserted to form two external connection ends for connecting electricity, and are also connection ends of a zero line and a fire wire inside the plug after being connected with the lead body 2.

One end of each pin 3 is distributed in an splayed structure when inserted into the shell 1, the surface of the shell 1 is provided with corresponding jacks 17, and two sides of each jack 7 are provided with limiting blocks 14 for fixing the pins 3 in a protruding mode. After the pins 3 are inserted, the limiting blocks 14 can enlarge the contact area with the two sides of the pins 3, so that the fixity of the pins 3 is effectively enhanced. In order to further enhance the stability of the pin 3, raised anti-slip parts 15 are added on both sides of the pin 3, and the anti-slip parts 15 synchronously slide when the pin 3 is inserted into the insertion holes 17 between the two limiting blocks 14, and finally the anti-slip parts 15 are embedded into the limiting blocks 14 to be fixed in the contact surfaces, so that the fixation is enhanced, and the pin 3 is prevented from sliding in the insertion holes 17.

The pin 3 is inserted into one end inside the shell 1, so that the pin is better connected with the lead body 2, and the pin 3 and the lead body are in a direct clamping and fixing mode, so that connection is convenient, and falling is avoided. Two pins 3 are inserted into one end and are provided with a clamping hole 4, and the size of the clamping hole 4 is the same as that of the battery cell 6 in the lead body 2, so that the whole battery cell 6 can be conveniently and smoothly fixed in the clamping hole 4, and the battery cell can not fall off. Meanwhile, a sliding groove 5 communicated with the clamping hole 4 is further arranged between the clamping hole 4 and the outer side surface of the pin 3, and when the electric core 6 is connected, the electric core 6 can directly slide into the clamping hole 4 at the tail end through the sliding groove 5, and in order to avoid that the electric core 6 assembled in the clamping hole 4 falls off from one end of the sliding groove 5, the opening of one end, connected with the clamping hole 4, of the sliding groove 5 is smaller than the maximum width of the clamping hole 4, namely, the opening is smaller than the outer diameter of the electric core 6.

When the inside of the shell 1 is connected with the lead body 2, the inside of the lead body 2 is composed of two bundles of electric cores 6, and thus, the two bundles of electric cores 6 can be connected with different pins 3 to form a live wire and a zero wire. After the battery cell 6 is fixed in the corresponding clamping hole 4, the tail end of the battery cell 6 is also provided with a raised insulation lug 7 to prevent the battery cell 6 from falling off after being pulled in the clamping hole 4. The whole connection structure is convenient and quick, the battery cell 6 is not separated from the pin 3 after being connected, and the battery cell is not fixed in a welding mode.

It should be noted that, the side of the shell 1 inserted with the pin 3 is provided with a convex snap ring 8, the pin 3 is arranged on the inner side of the snap ring 8 for fixing, and the snap ring 8 is convenient for fixing with the connecting piece inserted with the plug. The inner wall of the clamping ring 8 is provided with four raised clamping blocks 9, after the plug is plugged by the connecting piece, the contacted part can be screwed below the clamping blocks 9 in a rotating mode to be fixed, so that falling is avoided. In order to avoid deformation or damage of the pins 3 due to rotation, a first hollow 10 is provided at the position of the housing 1 where the pins 3 are inserted, which partly surrounds the pins 3. The first hollow portion 10 can be allowed to slightly deform at the position of the housing 1 where the pin 3 is inserted to facilitate fixing the inserted connection piece, and the connection with the pin 3 is not affected, even the pin 3 is not damaged.

The shell 1 surface still is equipped with bellied latch segment 11 and half surrounds this latch segment 11's second hollow 12, and latch segment 11 is equipped with the pressure portion 13 that extends to snap ring 8 outside, and this latch segment 11 can prevent the reverse rotation of connecting piece after the rotation through the bellied part that makes progress, further fixes the stability to inserting the connecting piece. When the connector is required to be disassembled, the user needs to press down the pressing part 13 by hand to separate the convex part, and then rotate the connector to disassemble.

In addition, when the wire body 2 extends inside and outside the shell 1, the joint of the shell 1 and the wire body 2 is provided with the wire protection sleeve 16, the wire body 2 extends outwards through the middle part of the wire protection sleeve 16, the wire protection sleeve 16 prevents the wire body 2 from wearing at the contact position of the shell 1, the wire body 2 is also protected from being broken easily, and the damage to the wire body 2 is reduced.

Compared with the prior art, when the plug that this technical scheme provided is connected with the pin 3 in the internal wire body 2, the electric core 6 part of the wire body 2 is direct to block into the card hole 4 internal fixation that the pin 3 corresponds, and the wire body 2 after the card is connected with the pin 3 after can not drop, and the equipment is convenient, and stability is good, simultaneously, connects between the two and need not be fixed through the welded mode, avoids the direct damage casing 1 of welding of high temperature.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
