The invention provides a quick cable connector for a switch cabinet, which is mainly used for connecting new electric appliances or circuits to electric circuits such as cables which are already laid, and is particularly suitable for connecting new circuits of the electric equipment such as the switch cabinet in the later stage after the front-stage cable laying is completed. It will be appreciated that the switchgear cable quick connector provided by the invention is equally applicable to cables that are being laid or not.
Specifically, as shown in fig. 1 to 8, the quick connector for a switch cabinet cable provided in the embodiment of the invention includes a clamping portion 100 and a blade portion 200, where the clamping portion 100 is used to clamp a cable to fix the quick connector for a switch cabinet cable on the cable, a clamping hole is formed in the clamping portion 100, and the cable passes through the clamping hole and is clamped with the clamping portion 100.
Blade 200 has mainly two functions, on the one hand blade 200 is intended to cut into the insulating coating of the cable so as to expose the cable core, and on the other hand blade 200 itself has an electrically conductive function to communicate the cable core with external equipment. The blade 200 is disposed at a side of the clamping portion 100 near the cable, that is, at a position of the clamping hole near the inner wall of the clamping hole. The blade 200 has a first tip 201 and a second tip 202 that are far away from each other, and the blade 200 can deform before and after the cable is threaded (i.e., before and after the blade 200 is electrically connected with the cable) and has a corresponding initial position and a clamping position: when in the initial position, as shown in fig. 7, the first tip 201 is close to the axis of the clamping hole, the second tip 202 is far away from the axis of the clamping hole, and at this time, the blade 200 forms an angle with the axis of the clamping hole (i.e. the axis of the cable), so that the first tip 201 is perpendicular to the axis of the clamping hole, and in this state, the first tip 201 can successfully puncture the outer insulation layer of the cable; when in the clamping position, as shown in fig. 8, the first tip 201 and the second tip 202 are both abutted against the cable core, at this time, the blade 200 is parallel to the axis of the clamping hole, the second tip 202 penetrates between the cable core and the outer insulating layer, and most of the blade 200 is in contact with the cable core. The blade 200 is made of an electrically conductive material.
Therefore, the quick connector for the switch cabinet cable provided by the embodiment of the invention can smoothly penetrate into the cable and be electrically connected with the cable through the deformation of the blade part 200, a new electrical circuit is quickly connected to an existing electrical circuit without cutting off a power supply and rewiring, and damage or poor contact to a cable cell is avoided in the connection process.
In one embodiment, the blade 200 is connected to the clamping portion 100 through an elastic connection portion 300, and the elastic connection portion 300 is capable of elastically deforming and moving the blade 200 from the initial position to the clamping position. Due to the provision of the elastic connection portion 300, in the process that the blade portion 200 moves from the initial position to the clamping position, the included angle between the blade portion 200 and the elastic connection portion 300 is reduced due to the obstruction of the cable outer insulation layer, and the blade portion 200 continues to move after the first tip 201 pierces the cable outer insulation layer and contacts the cable inner core until the second tip 202 contacts the cable inner core, at this time, the blade portion 200 is not obstructed by the cable outer insulation layer, the elastic force of the elastic connection portion 300 makes the second tip 202 move away from the first tip 201 and pierce the space between the cable outer insulation layer and the cable inner core, and in this process, the included angle between the blade portion 200 and the elastic connection portion 300 increases.
In one embodiment, the clamping portion 100 is provided with a pushing hole 101 and a pushing rod 102, the pushing rod 102 is arranged in the pushing hole 101 in a penetrating manner and can slide along the pushing hole 101, one end of the pushing rod 102 is provided with a pushing inclined plane 103, the pushing inclined plane 103 is abutted against the elastic connecting portion 300, and an inclined plane matched with the pushing inclined plane 103 can be arranged at the bottom of the elastic connecting portion 300; when the pushing rod 102 slides along the pushing hole 101, the pushing inclined plane 103 pushes the elastic connection part 300 to move upwards, and the elastic connection part 300 moves upwards to drive the blade part 200 to move, so that the initial position moves to the clamping position. Further, the pushing rod 102 is disposed such that the lower end of the initial position protrudes out of the pushing hole 101, and when the pushing rod 102 is pushed to move the blade 200 to the clamping position, the pushing rod 102 just completely enters the pushing hole 101.
In one embodiment, an elastic stop member 104 is disposed in the pushing hole 101, and the elastic force of the elastic stop member 104 always makes the pushing rod 102 move in the direction of exiting the pushing hole 101 or has a tendency to move in the direction of exiting the pushing hole 101, so that the pushing rod 102 can be pushed when a force exceeding a preset magnitude is applied to the pushing rod 102, thereby avoiding misoperation to move the blade 200 upwards and prevent the blade from resetting.
In one embodiment, the blade 200 is elastically deformable, and when in the initial position, a side surface of the blade 200 facing the axis of the clamping hole is a concave surface; in the clamping position, a side of the blade 200 facing the axis of the clamping hole is fitted with the outer contour of the cable core. The blade portion 200, which is elastically deformable, can make the contact area between the blade portion 200 and the outer insulation layer as small as possible when the blade portion 200 pierces the cable outer insulation layer, and has the contact area as large as possible when the blade portion 200 contacts the cable core.
In one embodiment, the clamping portion 100 includes two clamping half rings 120, and the two clamping half rings 120 are fixedly connected to form a clamping hole. Because the quick cable connector for a switch cabinet is usually used for wiring an existing line, it is difficult to make the end of the cable penetrate from one end of the quick cable connector for the switch cabinet, and the other end penetrates out, usually the quick cable connector for the switch cabinet is directly clamped or sleeved on the existing line, and the main body of the clamping part 100 is arranged into separate components, so that the quick cable connector for the switch cabinet can be conveniently operated on the existing line.
In one embodiment, a rotating connector is disposed at one side of the two clamping half rings 120, and the two clamping half rings 120 can rotate relatively through the rotating connector, so that the two clamping half rings 120 are formed into a movable relative whole.
In one embodiment, a joint of the two clamping half rings 120 is provided with a clamping protrusion 121 and a clamping groove 122, the clamping protrusion 121 is arranged on one clamping half ring 120, and the clamping groove 122 is arranged on the other clamping half ring 120; or, any clamping half ring 120 is provided with a clamping protrusion 121 and a clamping groove 122. After the two clamping half rings 120 are spliced, the clamping protrusions 121 are clamped into the clamping grooves 122, so that on one hand, the two clamping half rings 120 have a correct position relationship, and on the other hand, the clamping protrusions 121 and the clamping grooves 122 have a certain binding force, so that the two clamping half rings 120 are not easy to disengage.
In one embodiment, in order to further enhance the connection reliability between the two clamping half rings 120, one or both ends of the clamping half rings 120 are provided with connection threads, and after the two clamping half rings 120 are spliced, nuts or other fasteners with threads are sleeved on the connection threads, so that the two clamping half rings 120 are reliably connected. It should be noted that the connecting threads of the two clamping half rings 120 at the same end should be engaged with each other after being spliced.
In one embodiment, in order to further enhance the connection reliability between the two clamping half rings 120, one end or both ends of the clamping half rings 120 are provided with tapered sections, after the two clamping half rings 120 are spliced, fastening members such as snap rings are sleeved at the ends of the clamping half rings 120, and when the snap rings are pushed inwards, the tapered sections are pressed against, so that the two clamping half rings 120 are more tightly connected. It will be appreciated that the taper may be used with threads.
In one embodiment, the clamping portion 100 includes two locking half rings 130, and the two locking half rings 130 are spliced and sleeved at the end portions of the clamping half rings 120 to fixedly connect the two clamping half rings 120.
In one embodiment, the inner surface of the lock half ring 130 is provided with connecting threads.
In one embodiment, the quick cable connector of the switch cabinet further includes an electrical connector 400, where the electrical connector 400 is disposed through the clamping portion 100, and the electrical connector 400 is directly or indirectly electrically connected to the blade portion 200 through a cable or other manner, and is further electrically connected to the cable core.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
