As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1-4, a conductive quick release joint provided by an embodiment of the utility model is shown. Also known as couplers, quick plug devices. Which comprises a plug connector 1 and a plug pipe 2. The plug 1 comprises an inner sleeve 11, an outer sleeve 12, an elastic piece 13 and a clamping piece 14; at least two through holes 111 are formed in the circumferential direction of the inner sleeve 11, a clamping piece 14 is arranged in each through hole 111, the outer sleeve 12 is sleeved outside the inner sleeve 11 in a sliding mode, the outer sleeve 12 has an unlocking position and a locking position, and the elastic piece 13 is suitable for enabling the outer sleeve 12 to be located in the locking position. The inserting pipe 2 is provided with clamping holes 21 with the same number as the through holes 111, and the inserting pipe 2 can be inserted into the inner sleeve 11. When the outer sleeve 12 is in the locking position, the inner wall of the outer sleeve 12 is suitable for abutting against the clamping piece 14 so that the clamping piece 14 is fixed and partially exposed out of the through hole 111 to enter the inner sleeve 11, and the part of the clamping piece 14 exposed out of the through hole 111 is suitable for being clamped with the clamping hole 21; when the outer sleeve 12 is in the unlocked position by applying a force, the inner wall of the outer sleeve 12 releases the fixing of the snap-in piece 14, so that the snap-in piece 14 can be retracted from the inner sleeve 11 into the through hole 111.
In practical use, the female power supply terminal 6 is generally disposed in the inner sleeve 11, the male power supply terminal 7 is disposed in the plug tube 2, and when the plug tube 2 is inserted into the inner sleeve 11, the female power supply terminal 6 is electrically connected to the male power supply terminal 7.
The use mode of the conductive quick-release connector is as follows:
initially, the outer sleeve 12 is in the locking position by the elastic force of the elastic member 13 without external force, and in the locking position, the inner wall of the outer sleeve 12 abuts against the snap member 14, so that the snap member 14 is fixed and partially exposed from the through hole 111 into the inner sleeve 11. In this case, the insertion tube 2 will be blocked by the portion of the clamping member 14 exposed from the through hole 111 and cannot be inserted into the inner sleeve 11. In order to insert the insertion tube 2, an external force is applied to make the outer sleeve 12 overcome the elastic force of the elastic member 13 and be in an unlocking position, and at the moment, the inner wall of the outer sleeve 12 releases the fixation of the clamping member 14, so that when the insertion tube 2 is inserted, the outer wall of the insertion tube 2 pushes the part of the clamping member 14 exposed out of the through hole 111 back into the through hole 111, and the insertion of the insertion tube 2 is prevented from being blocked. After the outer sleeve 12 is inserted into the inner sleeve 11, the applied external force is removed, the outer sleeve 12 is reset to the locking position again under the action of the elastic element 13, and the portion of the clamping element 14 exposed out of the through hole 111 is clamped with the clamping hole 21, so that the locking of the plug 1 and the plug tube 2 is realized.
It can be seen from the above usage that the quick release connector can unlock the plug connector 1 and the plug pipe 2 only by applying force to slide the outer sleeve 12 on the inner sleeve 11 to the unlocking position; when the plug connector 1 and the plug pipe 2 are required to be locked, the elastic piece 13 can automatically reset the outer sleeve 12 to the locking position to realize locking only by canceling the external force, which is very convenient.
In addition, in the above arrangement, at least two through holes 111 are formed in the circumferential direction of the inner sleeve 11, the through holes 111 are provided with the engaging members 14, and the inserting tube 2 is provided with engaging holes 21 having the same number as the through holes 111. The number of at least two of these limits ensures the reliability of the connection of the plug connector 1.
In a preferred embodiment, the through hole 111 is a tapered hole, the smaller end of the tapered hole is located on the inner wall of the inner sleeve 11, and the larger end of the tapered hole is located on the outer wall of the inner sleeve 11; the snap-in members 14 are balls having a diameter smaller than the diameter of the larger end of the tapered bore but larger than the diameter of the smaller end of the tapered bore. That is, since the diameter of the ball is larger than that of the smaller end of the tapered hole, the ball will not be released from the smaller end of the tapered hole, and when the inner wall of the outer sleeve 12 abuts against the ball, the ball will be fixed in the tapered hole and partially exposed out of the tapered hole, thereby achieving the reliability of the engagement of the ball with the engagement hole 21.
Preferably, the snap-in hole 21 is a blind hole. Through such mode of setting, can promote the waterproof performance of grafting pipe 2, avoid the rainwater to follow joint hole 21 and carry out inside grafting pipe 2.
Preferably, an enlarged bore at one end of the outer sleeve 12 forms a first enlarged hole 121, and the first enlarged hole 121 is adapted to receive a portion of the snap 14, so that the snap 14 can be retracted from the inner sleeve 11 into the through hole 111. That is, a movable space is left for the clip 14 through the first enlarged hole 121, so that the portion of the clip 14 exposed from the through hole 111 can be retracted into the through hole 111.
Preferably, the hole wall of the first enlarged hole 121 is connected to the inner wall of the non-enlarged hole portion of the outer sleeve 12 by a slope 122. The inclined surface 122 plays a guiding role, so that the outer sleeve 12 and the clamping piece 14 are more smooth when being matched, and clamping stagnation is reduced.
Preferably, the second end of the outer sleeve 12 is enlarged in diameter to form a second enlarged hole 123, a limiting groove 124 is formed on the hole wall of the second enlarged hole 123, a limiting flange 112 is arranged on the outer wall of the inner sleeve 11, and the limiting flange 112 is located in the limiting groove 124; when the limit flange 112 abuts against one end of the limit groove 124 close to the through hole 111, the outer sleeve 12 is in the unlocking position; when the stop flange 112 abuts the end of the stop groove 124 remote from the through hole 111, the outer sleeve 12 is in the locked position. That is, in the present invention, the axial position of the outer sleeve 12 is specifically limited by the cooperation of the limiting groove 124 and the limiting flange 112. Further, the elastic element 13 is a spring, and the spring is sleeved outside the inner sleeve 11 and is located in the second enlarged hole 123. The second enlarged hole 123 can save the internal space, so that the conductive quick-release joint structure of the present invention is more compact.
Preferably, the outer sleeve 12 includes a front end 125 and a rear end 126, the rear end 126 being threadably received on the front end 125. By this arrangement, the mounting of the outer sleeve 12 on the inner sleeve 11 is facilitated.
Preferably, two sealing rings 3 are arranged on the insertion pipe 2, and the clamping hole 21 is positioned between the two sealing rings 3. Through setting up two sealing washer 3, can promote water-proof effects.
Preferably, the outer wall of the outer sleeve 12 is sleeved with an anti-slip rubber ring 127. The anti-skidding rubber ring 127 is convenient for manual operation, and the skidding phenomenon caused by rainwater in rainy days is reduced.
Of course, in the present invention, referring to fig. 5, the plug 1 can be screwed with the plug extension 4, and the plug tube 2 can be screwed with the plug tube extension 5. The connector extension piece 4 and the tube extension piece 5 may be used to enhance the covering of the electrical wire.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
