Description

Electric power connecting plug

Technical Field

The invention relates to a connecting plug, in particular to an electric power connecting plug.

Background

Through retrieval, patent number CN104953318B, discloses an electric power connection plug, which comprises a base body and a plug, wherein the base body is connected with a cable, the plug is detachably connected with the base body, two sides of the base body are provided with shallow grooves, positioning blocks are arranged in the shallow grooves, two sides of the plug are provided with positioning clips at corresponding positions, and the positioning clips are provided with clamping holes at corresponding positions.

In the patent document, the specification notes that "an inner cavity 9 is formed in the base 1, sliding grooves 15 are formed in inner walls of two sides of the inner cavity 9, sliding blocks 16 are arranged on two sides of the positioning block 6, the sliding blocks 16 are arranged in the sliding grooves 15, the positioning block 6 slides in the sliding grooves 15 through the sliding blocks 16 to realize relative sliding of the positioning block and the positioning block, and the inner cavity 9 limits the sliding stroke of the positioning block 6", and the conclusion that "the positioning block 6 can only move in a direction parallel to the sliding grooves 15" can be clearly deduced from the above description;

the specification of the patent document also discloses that "shallow grooves 5 are arranged on two sides of a substrate 1, positioning blocks 6 are arranged in the shallow grooves 5, positioning clamps 7 are arranged on two sides of a plug 2 at corresponding positions, clamping holes 8 are arranged at corresponding positions of the positioning clamps 7, and the clamping holes 8 are clamped at the positioning blocks 6", and by combining the specification drawings 1 and 2 of the patent document, if the positioning clamps are fixed by moving the positioning blocks, one end of the positioning block is required to pass through the clamping holes on the positioning clamps to meet the requirement for fixing;

however, how to mount the positioning clip is not described in the patent document, and the connection relationship between the positioning clip and the plug is not clearly described, if the positioning clip is fixedly connected, the scheme cannot be realized, and if the positioning clip is slidably connected, at least one positioning clip is required to be slidable to satisfy the fixing operation;

however, in this way (one positioning clip is slidable), firstly, the size of the plug is required to meet the movement requirement of the positioning clip, secondly, the problem of inconvenient operation exists in the way, firstly, the movable positioning clip is moved to the farthest position, then, the fixed positioning block is made to pass through the positioning block, then, the movable positioning clip is moved to make the movable positioning clip pass through the other positioning block, then, the fixed operation can be realized only by moving the positioning block, and the fixed operation and the later splitting operation are both inconvenient.

Disclosure of Invention

The present invention is directed to a power connection plug that solves the problems set forth in the background of the invention.

In order to achieve the purpose, the invention adopts the following technical scheme:

a power connecting plug comprises a base body and a plug, wherein the end faces of the base body and the plug are circular, two positioning grooves are symmetrically formed in the base body, two positioning clamps are symmetrically and fixedly mounted on the plug and clamped in the corresponding positioning grooves, a first cavity and two first grooves are formed in each of the two positioning clamps, the first cavity is communicated with the first grooves, two sliding blocks are slidably connected in the first cavities, one sides, close to each other, of the two sliding blocks are fixedly mounted with a first spring, and one sides, far away from the first spring, of the sliding blocks are fixedly mounted with an arc-shaped clamping seat through connecting rods;

two draw-in grooves with arc cassette matched with are all seted up to the inner wall of constant head tank, two mounting grooves and four two cavitys have been seted up on the base member, and two and corresponding draw-in grooves and mounting groove intercommunication, every all have one through two fixed mounting of two springs in the mounting groove to press the briquetting, every press equal fixed mounting has two to press the depression bar on the briquetting, and the one end of pressing the depression bar contacts with corresponding arc cassette.

In the above-mentioned electric power connection plug, each arc-shaped clamping seat is provided with an arc-shaped groove, and one end of the pressing rod, which is far away from the pressing block, is clamped in the corresponding arc-shaped groove, the groove width of the arc-shaped groove is equal to the thickness of the pressing rod, two of the positioning clamps are provided with a connecting groove, and the connecting groove is communicated with the corresponding groove.

In the above-mentioned electric power connection plug, each pressing block is fixedly sleeved with a first annular sealing ring.

In the above-mentioned electric power connection plug, two all fixed paste has sealed the pad on the inner wall of constant head tank, and has seted up the through-hole on the sealed pad, and the size of through-hole is greater than the size of recess one.

Compared with the prior art, the invention has the advantages that:

1: fixed easy and simple to handle between base member, the plug exerts a pressing force to four arc cassette with the hand, then promote the cavity one make the locating clip block to corresponding constant head tank in can, the spring one is in by compression state this moment, and the spring extension makes in the automatic block of arc cassette to corresponding draw-in groove when the arc cassette removes to draw-in groove position.

2: separation between base member, the plug is easy and simple to handle, exerts a thrust of keeping away from the base member to the plug when exerting pressure according to the briquetting and makes the arc cassette keep away from draw-in groove position, and it can to exert an external force of keeping away from the base member to the plug again.

3: the setting of spring one makes can be better when the arc cassette removes in the draw-in groove support tight block in the draw-in groove to make between the base member, the plug block fixed more firm, be convenient for according to the cooperation of depression bar and arc recess on the one hand push out the arc cassette better according to the depression bar, on the other hand utilizes the fixed effect between the multiplicable base member of the friction of the two, the plug.

4: the elasticity of sealed pad makes the location press from both sides more firm at the constant head tank internal fixation, and can also avoid the contact between the two, reduces the wearing and tearing that the dismouting in-process produced.

5: the arrangement of the connecting groove ensures that the pressing rod can not block the movement of the positioning clamp when the plug is moved out of the base body.

In summary, the base body and the plug are easy to disassemble and assemble, the fixing or the separation of the base body and the plug can be completed quickly, the base body and the plug are more firmly fixed through the matching of the arc-shaped clamping seat and the clamping groove, and the arc-shaped clamping seat is more easily and conveniently moved out of the clamping groove through the matching of the pressing block and the pressing rod.
