Technical Field

[0001] The utility model relates to the technical field of probe type connectors, in particular to a probe type connector. Background Art

[0002] At present, the application range of spring-type probe connectors is extremely wide. The probe connectors are usually welded on PCB boards to achieve the functions of transmission and conduction, including power supply, data transmission and signal transmission.

However, since the sealing cover needs to be removed first and then removed when the probe is disassembled, the disassembly speed is slow, and when the probe connector is in use, the probe and the sealing cover are generally perpendicular to the ground, which makes it easy for the sealing cover to fall off after disassembly, thereby possibly causing the loss of parts.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Please see attached Figure 1 -Attached Figure 5 A probe type connector comprises an outer tube 1, the inner cavity of the outer tube 1 is a hole structure, a probe 101 is fitted inside the outer tube 1, a disassembly assembly is arranged inside the outer tube 1, the disassembly assembly comprises a card slot 2 opened on the outer wall of the probe 101, four support frames 201 are fixed to the inner wall of the outer tube 1, a locking plate 202 is slidably arranged inside the support frame 201, one end of the locking plate 202 extends to the inside of the card slot 2, a driving rod 203 is fixed to the other end of the locking plate 202, four extension holes 207 are opened on the outer wall of the outer tube 1, one end of the driving rod 203 passes through the extension hole 207 and extends to the outside of the outer tube 1.

[0023] In the embodiment, a locking ring 204 is movably sleeved on the outer wall of the outer cylinder 1, and the abutment block 206 is a semicircular structure. The bottom surface of the probe 101 close to the outer side of the outer cylinder 1 is an inclined structure. The bottom surface of the inner wall of the slot 2 and the bottom surface of the locking plate 202 are both inclined structures. A spring 205 is fixed to the inner bottom surface of the outer cylinder 1, and an abutment block 206 is fixed to the top of the spring 205. The top surface of the abutment block 206 abuts against the bottom surface of the probe 101. By arranging the locking ring 204 on the outer cylinder 1 and inserting the probe 101 into the inner part of the outer cylinder 1, the locking ring 204 is then moved upward and the bottom inclined surface of the driving rod 203 is squeezed, so that the driving rod 203 is subjected to a force in the inner direction of the outer cylinder 1, so that the driving rod 203 drives the locking The plate 202 enters the interior of the card slot 2 and locks the probe 101, so that the probe 101 can slide up and down inside the outer tube 1 but cannot fall off the outer tube 1. When disassembling, the locking ring 204 is released. At this time, the elastic force of the spring 205 causes the probe 101 to move upward, so that the bottom surface of the locking plate 202 fits with the bottom surface of the locking plate 202, and the bottom surface of the inner wall of the card slot 2 and the bottom surface of the locking plate 202 are both inclined structures, so that the locking plate 202 is subjected to a force toward the outside of the outer tube 1, so that the locking plate 202 is automatically detached from the inside of the card slot 2, thereby realizing the installation and removal of the probe 101, the disassembly process is simple, the disassembly speed is fast, and at the same time, there is no need to remove the parts on the connector during disassembly to prevent the loss of parts.

[0024] In the embodiment, the bottom surface of the probe 101 is a sloped structure, and the abutment block 206 is a semicircular structure. By setting the bottom surface of the probe 101 to be a sloped structure and the abutment block 206 to be a semicircular structure, when the spring 205 applies elastic force to the abutment block 206 and squeezes the probe 101, the probe 101 is tilted inside the outer tube 1, so that the outer wall of the probe 101 is always in contact with the inner wall of the outer tube 1, ensuring that current flows between the outer tube 1 and the probe 101.

[0025] In the embodiment, the outer wall of the outer tube 1 is threadedly connected with a nut 3, and the locking ring 204 is fixed to the top surface of the nut 3. The locking ring 204 can be driven to move up and down and locked by rotating the nut 3.

[0026] In the embodiment, a limiting ring 301 is fixed on the outer wall of the outer cylinder 1 , and the limiting ring 301 is located above the locking ring 204 and the nut 3 . The limiting ring 301 can limit the nut 3 and the locking ring 204 .

[0027] In an embodiment, the distance between one end of the locking plate 202 and the inside of the slot 2 is equal to the distance between the outer wall of the probe 101 and the inside of the outer tube 1. By setting the distance between one end of the locking plate 202 and the inside of the slot 2 to be equal to the distance between the outer wall of the probe 101 and the inside of the outer tube 1, it can be ensured that the gap between the locking plate 202 and the slot 2 is not less than the gap between the probe 101 and the outer tube 1, thereby preventing the outer wall of the probe 101 from being unable to contact the inner wall of the outer tube 1.

[0028] Working principle: During use, the probe 101 is inserted into the outer tube 1, and then the nut 3 is rotated. Under the action of the threaded connection between the nut 3 and the outer wall of the outer tube 1, the nut 3 drives the locking ring 204 to move upward and squeezes the bottom inclined surface of the driving rod 203, so that the driving rod 203 is subjected to a force in the direction of the inner side of the outer tube 1, so that the driving rod 203 drives the locking plate 202 to enter the interior of the card slot 2 to lock the probe 101. When the probe 101 needs to be removed, the nut 3 is rotated in the opposite direction to drive the locking ring 204 to move downward, so that the locking ring 204 releases the locking of the driving rod 203. At this time, due to the elastic force of the spring 205, the probe 101 moves upward, so that the bottom surface of the locking plate 202 fits with the bottom surface of the locking plate 202, and the bottom surface of the inner wall of the card slot 2 and the bottom surface of the locking plate 202 are both inclined structures. , so that the locking plate 202 is subjected to a force in the direction of the outside of the outer tube 1, so that the locking plate 202 automatically disengages from the inside of the card slot 2, thereby realizing the installation and removal of the probe 101. By setting the abutment block 206 to be a semicircular structure, the bottom surface of the probe 101 is an inclined structure, so that the spring 205 applies elastic force to squeeze the probe 101, which will make the probe 101 as a whole tilt toward the inner wall of the outer tube 1, so that the probe 101 and the inner wall of the outer tube 1 are always in contact, and the current is kept flowing between the probe 101 and the outer tube 1. The locking ring 204 can be limited by the limiting ring 301. By setting the distance between one end of the locking plate 202 and the inside of the card slot 2 to be equal to the distance between the outer wall of the probe 101 and the inside of the outer tube 1, the locking plate 202 can be effectively prevented from hindering the probe 101 from tilting as a whole and fitting against the inner wall of the outer tube 1.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
