Abstract

The utility model belongs to the technical field of connectors, and particularly relates to a pin type connector with a connection protection function, which comprises a pin type connector body. A connecting frame is locked at one end of the pin type connector body through a screw, two symmetrically arranged storage grooves are formed in the connecting frame, and end covers are rotationally connected in the storage grooves through torsional springs; a buffer space is formed by keeping a certain distance between the end cover 4 and the port of the pin type connector, so that dust, sundries and other foreign matters can be more effectively prevented from directly entering the pin type connector. Compared with a directly attached cover plate, the distance design enables foreign matters to be deposited or blocked in the space before entering the port, thereby reducing the possibility of damage or performance influence caused by contact between the foreign matters and the pins. Therefore, the contact pin type connector is effectively protected, and resistance increase caused by dust pollution to the jacks is avoided due to normal use of the contact pin type connector.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model will be further described in connection with the specific implementation.

[0025] For example Figures 1 to 5As shown, the utility model discloses a kind of pin connectors with connection protection function, one end of pin connector body 1 is attached with connection frame 2 by screw, two symmetrical storage grooves 3 are set in the inside of connection frame 2, end cap 4 is rotatably connected in storage groove 3 by torsional spring, two symmetrical guide plates 5 are fixedly installed at the end of connection frame 2 away from pin connector body 1, and guide plate 5 is arc-shaped.Hollow elastic ring 6 is fixedly installed in storage groove 3, gas outlet pipe 7 is fixedly installed in connection frame 2, and one end of gas outlet pipe 7 is communicated with the inside of elastic ring 6.Several grooves are set in guide plate 5, and several rolling columns 8 of rubber material are rotatably connected in the groove of guide plate 5.

[0026] When working, connection frame 2 is attached on the port of pin connector body 1 by screw, two end caps 4 in connection frame 2 are in initial state of closure, so as to close and protect the port of pin connector body 1, and there is still a gap between end cap 4 and the port of pin connector body 1.End cap 4 keeps a certain distance from the port of pin connector to form a buffer space, which can more effectively block dust, sundries and other foreign matters from directly entering pin connector.Compared with directly attached cover plate, the design with distance can make foreign matters deposit or be blocked in the space before entering the port, reducing the possibility of damage or affecting performance caused by foreign matters contacting pin.Further, pin connector is effectively protected, and dust pollution of jack is avoided to cause resistance increase, because pin connector is normally used.

[0027] When pin connector needs to be used, external data line interface is inserted into connection frame 2, at this time, arc-shaped guide plate 5 and several rolling columns 8 assist data line interface to enter into connection frame 2, and data line interface contacts two end caps 4 and is lifted up, so that two end caps 4 rotate into two storage grooves 3, and extrude elastic ring 6 in storage groove 3 to make it deform.Gas in deformed elastic ring 6 is sprayed to data line interface through gas outlet pipe 7, so as to assist cleaning data line interface, and reduce dust at the end of data line interface to affect subsequent use.Meanwhile, deflated elastic ring 6 can compensate the gap between end cap 4 and storage groove 3, increase friction, and assist end cap 4 to be better fixed in storage groove 3.It should be noted that when data line interface leaves connection frame 2, end cap 4 will rotate and reset under the action of torsional spring, so as to re-close connection frame 2.

[0028] Two rectangular grooves 9 are symmetrically arranged in the connecting frame 2, and the rectangular grooves 9 are closer to the guide plate 5 than the receiving grooves 3. A sliding rod 10 is slidably connected in the rectangular groove 9, and a spring is fixedly installed between the sliding rod 10 and the connecting frame 2. A "U"-shaped clamping plate 11 is fixedly installed at one end of the sliding rod 10. Limiting grooves 13 are arranged at both ends of the clamping plate 11. Two symmetrically arranged limiting blocks 12 are fixedly installed in the rectangular groove 9, and the limiting blocks 12 are made of rubber. Two symmetrically arranged connecting blocks 14 are fixedly installed on the inner wall of the clamping plate 11, and the connecting blocks 14 are made of flexible material.

[0029] In operation, before entering the connecting frame 2, the data line interface first pulls the two sliding rods 10, so that the two sliding rods 10 slide away from each other with the two clamping plates 11, and the clamping plates 11 enter the rectangular grooves 9. When the clamping plates 11 enter the rectangular grooves 9, the limiting blocks 12 made of rubber are extruded, so that the limiting blocks 12 are deformed. As the clamping plates 11 continue to move upward, the limiting grooves 13 at both ends of the limiting blocks 12 and the clamping plates 11 are in the same plane, so that the limiting blocks 12 are reset and clamped in the limiting grooves 13, thereby fixing the clamping plates 11, facilitating the data line interface to enter the connecting frame 2. After the data line interface is connected with the pin connector, the sliding rod 10 is pushed to force the clamping plate 11 to leave the rectangular groove 9, and the "U"-shaped clamping plate 11 clamps and fixes the data interface. At the same time, the two connecting blocks 14 in the clamping plate 11 compensate for the gap and more stably fit and clamp the data line interface. By fixing the data line interface, it effectively prevents it from shaking after loosening, causing the data line interface to wear and need to be replaced regularly, ensuring that the data line interface can be used stably for a long time.

[0030] Working principle: the connecting frame 2 is locked on the port of the pin connector body 1 by a screw, and the two end covers 4 in the connecting frame 2 are in the initial state of being closed. When the pin connector needs to be used, the external data line interface is inserted into the connecting frame 2. At this time, the arc-shaped guide plate 5 and the plurality of rolling columns 8 assist the data line interface to enter the connecting frame 2, and the data line interface contacts and lifts the two end covers 4, so that the two end covers 4 rotate into the two receiving grooves 3 and extrude the elastic ring 6 in the receiving groove 3 to deform. The gas in the deformed elastic ring 6 is sprayed to the data line interface through the gas outlet pipe 7. At the same time, the deflated elastic ring 6 can compensate the gap between the end cover 4 and the receiving groove 3.

[0031] The data line interface is pulled to make the two slide rods 10 slide away from each other, and the two clamping plates 11 slide into the rectangular slot 9. When the clamping plates 11 slide into the rectangular slot 9, the limiting blocks 12 made of rubber are pressed to deform, and the limiting slots 13 at the two ends of the clamping plates 11 are in the same plane, so that the limiting blocks 12 are reset into the limiting slots 13, thereby fixing the clamping plates 11, and the data line interface is conveniently connected to the connecting frame 2. When the data line interface is connected to the pin connector, the slide rods 10 are pushed to make the clamping plates 11 leave the rectangular slot 9, and the data line interface is clamped and fixed by the "U"-shaped clamping plates 11. At the same time, the two connecting blocks 14 in the clamping plates 11 compensate the gap and more stably fit and clamp the data line interface.
