The using method of the invention is as follows:
as shown in fig. 1 to 8, when the assembly is assembled, the guide rod 21 on the locking block extends into the guide groove 13 on the housing 1, meanwhile, the limiting rod 24 extends into the abdicating hole 14, and the locking block 23 extends into the stopping hole 11; then, on the other side of the housing 1, a first movable slider 331 sleeved with a first sealing ring 41 is placed in the placing hole 17, a second movable slider 332 is placed in the mounting hole, a compression spring 36 is sleeved on the connecting column 35, the upper end surface of the compression spring 36 abuts against the lower end surface of the connecting plate, the lower end surface of the compression spring 36 abuts against the step surface of the step groove on the supporting block 37, at this time, a contact block 4 fixedly arranged at the lower end of the second movable slider 332 is positioned right above the first opening 61 and the second opening 62, that is, the contact block 4 is positioned right above the exposed positions of the first contact piece 53 and the second contact piece 54; finally, the second sealing ring 42 is placed in a cavity structure formed by the first mounting groove 71 and the second mounting groove 72 in a surrounding mode, the orientation block 32 is moved into the orientation groove 16, the insertion block 31 at the corresponding end and the clamping hole in the fixing block 15 are clamped and fixed mutually, and the mounting shell 3 is fixedly connected with the shell 1.
Before use, as shown in fig. 1, 9, 10 and 11, one end of the first insert 51 extends out of the mounting case 3, and the other end extends into the connecting groove 38; one end of the second inserting bar 52 extends out of the mounting shell 3, the other end of the second inserting bar is connected with a first contact piece 53 arranged in the mounting shell 3, and the first contact piece 53 is exposed at the position of the first opening 61; one end of the second contact piece 54 extends into the connecting groove 38, and the other end is exposed at the position of the second opening 62; one end of the first inserting strip 51 and one end of the second inserting strip 52 are respectively connected with the positive pole and the negative pole of a power supply, the connecting groove 38 is plugged in the corresponding accessory, namely, the other end of the first inserting strip 51 and the second contact 54 are respectively communicated with the positive pole and the negative pole of the accessory, and at the moment, the first contact 53 and the second contact 54 are not communicated, namely, the circuit is not communicated.
As shown in fig. 12 to 15, when the contact block 4 is used, the male plug is inserted into the housing 1, the lower end surface of the boss 25 abuts against the transition inclined surface 231, and the latch 23 is extruded out of the stop hole 11, in the process, one side of the boss 25 further presses the first inclined surface 341 on the first movable slider 331, the first movable slider 331 is pressed to move to the left and abuts against and presses the second inclined surface 342 to drive the second movable slider 332 to move downwards and press the compression spring 36 at the same time, when the contact block 4 moves downwards to the right, one side of the lower end of the contact block 4 abuts against the first contact piece 53, and the other side abuts against the second contact piece 54, so that the circuit is communicated; meanwhile, the boss 25 is always abutted to the first movable sliding block 331 to keep extrusion on the second movable sliding block 332, then the locking block is pressed in, the clamping block 23 moves into the limiting groove through the limiting boss 121, in addition, the limiting block 12 is limited, the clamping block 23 is clamped and fixed in the limiting groove, at the moment, the limiting rod 24 moves above the boss 25, the lower end face of the limiting rod 24 is abutted to the upper end face of the boss 25 for limitation, thus, the boss 25 and the first movable sliding block 331 are kept in a stable abutting state, and the stability of the circuit communication state is improved.
When the male plug needs to be taken out, the supporting rod 22 only needs to be pulled outwards, the clamping block 23 leaves the limiting groove, the block body 2 is pulled to move outwards, the clamping block 23 moves into the stop hole 11, the limiting rod 24 leaves the upper portion of the boss 25, the male plug is pulled upwards, the circuit is disconnected, then, under the action of the elastic force of the pressure spring 36, the second movable sliding block 332 is driven to move upwards, the first movable sliding block 331 is ejected rightwards to return to the position to be connected through the second inclined surface 342, and the operation is convenient and fast.
In the above process, because a sealing ring (as shown in fig. 1, not labeled) is conventionally arranged between the male plug and the housing 1, when the male plug is inserted, the up-down direction of the position shown in the figure is a sealing state, the boss 25 and the sealing ring on the male plug divide the inner cavity of the housing 1 into two parts, as shown in fig. 14, a second sealing ring 42 is arranged between the mounting shell 3 and the housing 1, which can prevent external air and liquid from entering and improve the air tightness of mounting; meanwhile, the upper part of the boss 25 is directly communicated with the outside air, and the placing hole 17 is located above the boss 25, that is, the first sealing ring 41 is arranged between the first movable sliding block 331 and the placing hole 17 to prevent air and liquid from entering the mounting shell 3, so as to avoid affecting the use efficiency of the gas for the vehicle.
In addition, the first sealing ring 41 is arranged to be in interference fit with the placing hole 17, and on the premise that the sealing performance is not affected, the smooth movement of the first movable sliding block 331 is ensured, namely, the pressure spring 36 with proper elasticity is selected, and a proper clearance value of interference fit is set; the connecting hole 18 is mainly used for avoiding assembly interference and playing a role of space abdication, and in order to simplify the structure and ensure the sealing property, the connecting hole 18 is not communicated with the jack of the shell 1; because installation shell 3 and inserted block 31 are injection moulding integrated into one piece and make, the locking piece is also that plastic material makes, and the material of adoption is nylon 66, has certain elastic characteristic, and the inclined plane 311 of stepping down that sets up has not only reduced the resistance that inserted block 31 inserted the card hole, when taking off installation shell 3, can extrude inserted block 31 or directional block 32 position, and it warp to correspond the installation hole pore wall position department on messenger's installation shell 3, thereby makes inserted block 31 shift out the card hole and take off installation shell 3.
