Description

Technical Field

[0001] The invention belongs to the technical field of cable connectors, and in particular relates to a quick-insertion shielded cable front connector assembly. Background Art

[0002] Shielded cable front connector assemblies are usually used to connect shielded cables. Shielded cables are usually used in situations where external electromagnetic interference needs to be suppressed or electromagnetic leakage needs to be prevented, such as high-frequency signal transmission, industrial control systems, etc. The design of shielded cable front connector assemblies will take into account the need for electromagnetic shielding to ensure that the shielding performance of the cable is not destroyed during the connection process. These connector assemblies usually include a metal shell and a conductive shielding layer, as well as appropriate contacts to ensure good connection and shielding effects.

[0003] The existing connection method of the shielded cable front connector assembly is to connect the cable front connector with the connection end in the cable shielding box through a large number of fixing bolts.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) A quick-insert shielded cable front connector assembly, when the cable connector is connected, the cable connector is inserted into the limiting protrusion and the cable connector is moved to the point where it is in contact with the surface of the connection end. At this time, the rotating column is manually pressed to squeeze the connection seat through the rotating seat, so that the connection seat moves downward and squeezes the first spring. When the connection seat moves downward, the limiting slider is moved toward the outer end of the sliding groove through the action of the hinge rod, that is, part of the limiting protrusion is moved out, and the moved limiting slider limits the top of the cable connector, so that the cable connector is always tightly connected to the connection end in a crimped connection mode. When the rotating column is pressed downward, the connection block on its circumferential surface slides toward the bottom of the limiting groove. When it slides to the bottom of the limiting groove, the rotating seat The limit slider will then move to the vertical end of the limit slot when the cable connector is in a crimped state and the locking cam is in place to release the locking cam.

[0013] (2) This kind of quick-insert shielded cable front connector assembly, before the cable body enters the cable shielding box, the connecting bolt is first connected to the inside of the through groove through the connecting internal thread, and then the cable connector of the cable body is entered into the cable shielding box through the connecting bolt. When the cable body enters a certain part of the cable shielding box, the fixed limit plate on the circumferential surface of the cable body will abut against the limit convex plate inside the connecting bolt. When the fixed limit abuts against the limit convex plate inside the connecting bolt, the cable connector is inserted into the inside of the limit convex block and crimped with the connecting end through the fixing mechanism, and then the connecting nut is threadedly connected to the connecting bolt through the connecting external thread. In the process of threaded connection between the connecting nut and the connecting bolt, the sealing connection pad inside the connecting nut will also As it rotates and enters the inner side of the connecting bolt, the fixed limit plate and the limit convex plate are tightly squeezed, thereby not only achieving the effect of sealing and isolation, but also further limiting the position of the cable body. The traditional sealing connection pad is a separate individual, and is manually inserted into the inside of the connecting bolt for fixing the cable during sealing. On the one hand, this method makes it difficult to completely insert the sealing connection pad into the inside of the connecting bolt, resulting in an insufficient sealing effect. On the other hand, it is not convenient to remove it. In this method, since the sealing connection pad is connected to the connecting nut, the method of entering the connecting bolt is to rotate it, which can better enable the sealing connection pad to completely enter the inside of the connecting bolt. At the same time, it will be taken out together with the connecting nut during removal, which is more convenient and reduces the number of connection steps.

[0014] (3) This quick-insert shielded cable front connector assembly can operate a servo motor when the temperature inside the cable shielding box is too high. When the servo motor operates, it can drive the fan blades to rotate. The rotation of the fan blades can accelerate the air flow around the heat sink in the heat sink, thereby reducing the surface temperature of the heat sink. When the temperature of the heat sink surface is reduced, the temperature inside the cable shielding box can be reduced by heat conduction, thereby reducing the temperature inside the cable shielding box without affecting the sealing of the cable shielding box. By reducing the temperature inside the cable shielding box, the cable can be protected in a good working condition. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] It should be noted that when the cable connector 13a is not sleeved on the circumferential surface of the limiting protrusion 21, the connecting block 29 on the circumferential surface of the rotating column 28 is located in the vertical section of the limiting groove 212, that is, at this time, the rotating column 28 is slidably connected with the limiting groove 212 in the vertical direction through the connecting block 29. At this time, under the action of the first spring 25, the connecting seat 24 will make the rotating column 28 partially located outside the limiting cover 211. At the same time, under the action of the first spring 25 and the hinged rod 26, the limiting slider 23 is completely located inside the sliding groove 22. When the cable body 13 is connected to the inside of the cable shielding box 10, the cable connector 13a is connected through the through The groove 14 enters the interior of the cable shielding box 10, and then the circular groove in the middle of the cable connector 13a is used to make the cable connector 13a enter the limiting protrusion 21 and move the cable connector 13a to the surface of the connecting end 12. At this time, the rotating column 28 is pressed by manually twisting the protrusion 210, so that the rotating column 28 squeezes the connecting seat 24 through the rotating seat 27, so that the connecting seat 24 moves downward and squeezes the first spring 25. When the connecting seat 24 moves downward, the limiting slider 23 is moved toward the outer end of the sliding groove 22 through the action of the hinge rod 26, that is, part of it will move out of the limiting protrusion 21, and the moving limiting slider 23 will limit the top of the cable connector 13a, so that the cable connector 13a is always tightly connected with the connecting terminal 12 in a crimped connection mode. When the rotating column 28 is pressed downward, the connecting block 29 on its circumferential surface slides toward the bottom of the limiting groove 212. When it slides to the bottom of the limiting groove 212, the rotating column 28 is rotated under the action of the rotating seat 27, so that the connecting block 29 on the circumferential surface of the rotating column 28 moves to the inner side of the horizontal end of the limiting groove 212. At this time, the position of the rotating column 28 on the limiting cover 211 will be fixed, so that the limiting slider 23 squeezes the cable connector 13a so that it is always in a crimped connection with the connecting terminal 12. Crimping method, when it is necessary to release the crimped connection between the cable connector 13a and the connecting terminal 12, it is only necessary to move the rotating column 28 to drive the connecting block 29 to the vertical end of the limiting groove 212. At this time, under the action of the first spring 25, the limiting slider 23 will shrink to the inside of the sliding groove 22, so that the limiting slider 23 will no longer limit the cable connector 13a. At this time, the cable connector 13a can be taken out from the limiting protrusion 21. This method changes the traditional method of fixing with bolts, greatly facilitates the connection and fixation of the cable connector 13a and the connecting terminal 12 in the cable shielding box 10, saves time and effort, and is convenient and quick.

[0033] The connecting assembly 30 includes a connecting bolt 31 and a connecting nut 32. The circumferential surface of the connecting bolt 31 is provided with a connecting internal thread 31a, and the connecting internal thread 31a can be connected to the external thread inside the through groove 14. A first hexagonal fixing seat 31b is provided in the middle of the connecting bolt 31, and a limiting cam 31c is provided on the inner side of the connecting end of the connecting bolt 31 and the through groove 14. The inner circumferential surface of the connecting nut 32 is provided with a connecting external thread 32a, and the connecting external thread 32a can be threadedly connected to the connecting internal thread 31a. A second hexagonal fixing seat 32b is provided on the circumferential surface of the connecting nut 32, and a sealing connecting gasket 32c is connected to the inner side of the connecting nut 32.

[0034] It should be noted that before the cable body 13 enters the cable shielding box 10, the first hexagonal fixing seat 31b is first used to make the connecting bolt 31 threadedly connected to the inside of the through groove 14 through the connecting internal thread 31a, and then the cable connector 13a of the cable body 13 is passed through the connecting bolt 31 to enter the inside of the cable shielding box 10. When the cable body 13 enters a certain part of the cable shielding box 10, the fixed limiting plate 13b on the circumferential surface of the cable body 13 will abut against the limiting convex inside the connecting bolt 31. The cable body 13 that enters the cable shielding box 10 has a length that allows the cable connector 13a to be inserted into the limiting protrusion 21 and to be crimped with the connecting terminal 12. When the limiting plate 13b is fixed against the limiting protrusion 31c inside the connecting bolt 31, the cable connector 13a is inserted into the limiting protrusion 21 and is crimped with the connecting terminal 12 through the fixing mechanism 20. Then, the second hexagonal fixing seat 32b is used to connect the connecting nut 32 with the connecting nut through the connecting external thread 32a. The bolt 31 is threadedly connected. During the process of threaded connection between the connecting nut 32 and the connecting bolt 31, the sealing connection gasket 32c on the inner side of the connecting nut 32 will also rotate and enter the inner side of the connecting bolt 31, and tightly squeeze the fixed limiting plate 13b and the limiting convex plate 31c, thereby not only achieving the effect of sealing isolation, but also further limiting the position of the cable body 13. The traditional sealing connection gasket 32c is a separate individual, and is manually inserted into the inside of the connecting bolt 31 for fixing the cable during sealing. On the one hand, this method makes it difficult to completely insert the sealing connection gasket 32c into the inside of the connecting bolt 31, so that the sealing effect is not tight enough. On the other hand, it is not convenient to remove it when taking it out. In this method, since the sealing connection gasket 32c is connected to the connecting nut 32, the way to enter the connecting bolt 31 is to rotate and enter, which can better make the sealing connection gasket 32c completely enter the inside of the connecting bolt 31, and at the same time, it will be taken out together with the connecting nut 32 when taking it out, which is more convenient and reduces the connection steps.

[0035] The heat dissipation mechanism 40 includes a cover plate 41, a sealing gasket 42 is provided on the lower surface of the cover plate 41, a support seat 43 is provided on the lower surface of the cover plate 41, a heat sink 44 is plugged into the interior of the cover plate 41, and the bottom end of the heat sink 44 located on the inner side of the cover plate 41 is engaged in the interior of the support seat 43, wherein a sealing ring is provided at the connection between the heat sink 44 and the cover plate 41, a heat sink 45 is provided on the upper surface of the cover plate 41, an air inlet groove is provided at the top of the heat sink 45, wherein a plurality of air outlets are provided on the side of the heat sink 45, a support plate 46 is provided inside the air inlet groove, a servo motor 47 is provided on the side of the support plate 46, the output end of the servo motor 47 is transmission-connected with a fan blade 48, and a dustproof net 49 is provided inside the air inlet groove.

[0036] It should be noted that after the cable body 13 is fixed in the cable shielding box 10, the sealing gasket 42 at the bottom of the cover plate 41 is placed in the groove 11, and then the cable shielding box 10 and the cover plate 41 are fixed through the connecting mechanism 50. The sealing gasket 42 can protect the sealing of the cable shielding box 10. When the temperature inside the cable shielding box 10 is too high, the servo motor 47 can be operated. When the servo motor 47 is working, the fan blades 48 can be driven to rotate. The rotation of the fan blades 48 can accelerate the air flow around the heat sink 44 in the heat sink 45, thereby reducing the surface temperature of the heat sink 44. When the temperature of the surface of the heat sink 44 is reduced, the temperature inside the cable shielding box 10 can be reduced by heat conduction. Without affecting the sealing of the cable shielding box 10, the temperature inside the cable shielding box 10 can also be reduced. By reducing the temperature inside the cable shielding box 10, the cable can be protected from being in a good working condition.

[0037] The connecting mechanism 50 includes a socket 51, and the socket 51 is arranged on the side of the cable shielding box 10. The inner bottom wall of the socket 51 is provided with a second spring 52, and the end of the second spring 52 away from the inner bottom wall of the socket 51 is provided with a top plate 53. A positioning groove 54 is provided on the side of the socket 51, and a plug-in column 55 is provided on the side of the cover plate 41. A card slot 56 is provided inside the plug-in column 55, and a card block 58 is slidably connected inside the card slot 56. A third spring 57 is provided between the inner side wall of the card slot 56 and the card block 58.

[0038] It should be noted that the connecting mechanism 50 can be set in corresponding numbers according to the size and shape of the cable shielding box 10, and can also be distributed at the four corners of the corresponding box body. When the cover plate 41 and the cable shielding box 10 are sealed and fixed, the plug-in column 55 can be removed and inserted into the plug-in seat 51. When the plug-in column 55 is removed and inserted into the plug-in seat 51, the plug-in column 55 will squeeze the second spring 52 through the top plate 53. When the position of the block 58 in the plug-in column 55 moves to the position of the positioning groove 54 of the plug-in seat 51, Under the action of the third spring 57, the card block 58 will be pushed out to the outside of the positioning groove 54 and stuck into the positioning groove 54. At this time, the cover plate 41 and the cable shielding box 10 will be in a sealed and fixed state. When the cable shielding box 10 needs to be opened, just press the card block 58 toward the inside of the card slot 56. At this time, under the action of the second spring 52 and the top plate 53, the plug-in column 55 will pop out to the outside of the socket 51, and the cover plate 41 and the cable shielding box 10 can be released from the fixed state.

[0039] The working principle and use process of the present invention:

[0040] Before the cable body 13 enters the cable shielding box 10, the first hexagonal fixing seat 31b is used to thread the connecting bolt 31 into the interior of the through groove 14 through the connecting internal thread 31a, and then the cable connector 13a of the cable body 13 is passed through the connecting bolt 31 to enter the interior of the cable shielding box 10. When the cable body 13 enters a certain part of the cable shielding box 10, the fixed limiting plate 13b on the circumferential surface of the cable body 13 will abut against the limiting convex plate 31c inside the connecting bolt 31. When the fixed limiting plate 13b is against the limiting convex plate 31c inside the connecting bolt 31, the cable connector 13a is inserted into the limiting convex block 21 by using the circular groove in the middle of the cable connector 13a, and the cable connector 13a is moved to the position where it is connected to the surface of the connecting terminal 12. At this time, the rotating column 28 is pressed by manually twisting the convex block 210, so that the rotating column 28 squeezes the connecting seat 24 through the rotating seat 27, so that the connecting seat 24 moves downward and squeezes the first spring 25. When the connecting seat 24 moves downward, The action of the hinge rod 26 will cause the limit slider 23 to move toward the outer end of the sliding groove 22, that is, it will partially move out of the limit protrusion 21, and the moved limit slider 23 will limit the top of the cable connector 13a, so that the cable connector 13a is always tightly connected with the connecting terminal 12 in a crimping connection mode. When the rotating column 28 is pressed downward, the connecting block 29 on its circumferential surface slides toward the bottom of the limit groove 212. When it slides to the bottom of the limit groove 212, the rotating column 28 is rotated under the action of the rotating seat 27, so that the connecting block 29 on the circumferential surface of the rotating column 28 moves to the inner side of the horizontal end of the limit groove 212. At this time, the rotating column 28 will be fixed in the position of the limit cover 211, so that the limit slider 23 squeezes the cable connector 13a so that it is always in a crimping connection with the connecting terminal 12. This method changes the traditional method of fixing with bolts, greatly facilitates the connection and fixation of the cable connector 13a and the connecting terminal 12 in the cable shielding box 10, saves time and effort, and is convenient and fast;

[0041] The cable connector 13a is inserted into the interior of the limiting protrusion 21 and is crimped with the connecting end 12 through the fixing mechanism 20. Then, the second hexagonal fixing seat 32b is used to thread the connecting nut 32 with the connecting bolt 31 through the connecting external thread 32a. During the threaded connection between the connecting nut 32 and the connecting bolt 31, the sealing connection pad 32c inside the connecting nut 32 will also rotate and enter the inside of the connecting bolt 31, and the fixed limiting plate 13b and the limiting protrusion 31c are tightly squeezed, thereby achieving the effect of sealing and isolation and also limiting the position of the cable body 13.

[0042] When the cable body 13 is fixed in the cable shielding box 10, the sealing gasket 42 at the bottom of the cover plate 41 is placed in the groove 11, and the plug-in column 55 is inserted into the plug-in seat 51. When the plug-in column 55 is inserted into the plug-in seat 51, the plug-in column 55 will squeeze the second spring 52 through the top plate 53. When the position of the block 58 in the plug-in column 55 moves to the position of the positioning groove 54 of the plug-in seat 51, under the action of the third spring 57, the block 58 will be ejected to the outside of the positioning groove 54 and stuck in the positioning groove 54. At this time, the cover plate 41 and the cable shielding box 10 will be in a sealed and fixed state. When the cable shielding box 10 needs to be opened, it is only necessary to press the block 58 toward the inside of the card groove 56. At this time, under the action of the second spring 52 and the top plate 53, the plug-in column 55 will pop out to the outside of the plug-in seat 51, and the fixed state of the cover plate 41 and the cable shielding box 10 can be released.

[0043] When the temperature inside the cable shielding box 10 is too high, the servo motor 47 can be operated. When the servo motor 47 is operating, the fan blades 48 can be driven to rotate. The rotation of the fan blades 48 can accelerate the air flow around the heat sink 44 in the heat sink 45, thereby reducing the surface temperature of the heat sink 44. When the temperature on the surface of the heat sink 44 is reduced, the temperature inside the cable shielding box 10 can be reduced by heat conduction, thereby reducing the temperature inside the cable shielding box 10 without affecting the sealing of the cable shielding box 10. By reducing the temperature inside the cable shielding box 10, the cable can be protected from being in good working condition.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
