Description

Technical Field

[0001] The utility model relates to the technical field of conductive contacts, in particular to a conductive contact of a connector. Background Art

[0002] The conductive contacts of the connector are mainly used to electrically connect the withdrawable components in the low-voltage withdrawable switchgear to the connecting pieces of the busbars or other components.

[0003] The existing connection method between the conductive contact and the wire is mostly to insert the front end stripped section of the wire into the threading hole of the conductive contact, and then screw a bolt into the threading hole to tighten and fix the front end stripped section of the wire with the bolt. Although this method can achieve simple fixed installation of the wire to a certain extent, it lacks the fixing action for other positions of the wire, resulting in the wire being pulled during shaking or maintenance, which will affect the normal use of the front end stripped section and even cause breakage. Utility Model Content

[0004] In order to solve the above technical problems, a conductive contact of a connector is provided, which solves the problem in the prior art that when the wire is shaken or pulled during maintenance, it will affect the normal use of the front stripping section and even cause breakage.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a conductive contact of a connector, comprising a wire pressing section, a plug-in connecting section fixed to one side of the wire pressing section, and a threading hole opened on the other side of the wire pressing section, a mounting hole connected to the threading hole is opened on the top of the wire pressing section, a clamping bolt is threaded through the inner thread of the mounting hole, and a reinforcing mechanism is arranged outside the threading hole and a covering protection mechanism is arranged on the wire pressing section;

[0006] The reinforcing mechanism comprises a threaded sleeve vertically fixed on the side wall of the wire compression section and a plurality of compression rods fixed around the end of the threaded sleeve, an extrusion block is fixed on the side of the end of the compression rod facing the central axis of the threaded sleeve, and an extrusion component is slidably arranged on the outer wall of the threaded sleeve;

[0007] The covering and protecting mechanism comprises a covering sheet slidably arranged on the top surface of the wire pressing section.

[0008] Preferably, the extrusion component includes a threaded sleeve threadedly connected to the outer wall of the threaded sleeve and a movable pressing sleeve fixed to the side of the threaded sleeve away from the wire compression section, the inner cavity of the movable pressing sleeve is truncated cone-shaped, and the side of the end of the pressure rod away from the central axis of the threaded sleeve is inclined and in contact with the inner wall of the movable pressing sleeve.

[0009] Preferably, slide grooves are symmetrically provided on the bottom surface of the cover sheet, and a slider fixedly connected to the top surface of the wire pressing section is slidably arranged in the slide groove.

[0010] Preferably, a compression spring is fixed between the sliding block and an inner wall of one side of the sliding groove.

[0011] Compared with the prior art, the advantages of the utility model are:

[0012] (1) Through the setting of the reinforcement mechanism, after the guide is inserted into the threading hole, the threaded sleeve in the reinforcement mechanism is twisted toward the side of the wire pressing section, so that the movable pressing sleeve slides in the same direction as the threaded sleeve. In this way, the end of the pressure rod is continuously squeezed and bent during the movement of the movable pressing sleeve, and the extrusion block contacts the outer wall of the wire to form pressure on the wire. In this way, the extrusion blocks on several pressure rods cooperate to compress the outer wall of the wire from multiple points outside the wire pressing section, thereby improving the connection strength between the wire and the wire pressing section, so as to prevent the wire from affecting the normal use of its front end stripping section when it is pulled.

[0013] (2) Through the setting of the covering protection mechanism, when the knob thread sleeve is turned toward one side of the wire clamping section, the thread sleeve can simultaneously squeeze the covering piece, causing the covering piece to slide on the wire clamping section until the covering piece moves above the clamping bolt. The covering piece can effectively cover and protect the clamping bolt to prevent the clamping bolt from being exposed to the environment for a long time and being easily affected by rust.

[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0020] Reference Figure 1-3As shown, a conductive contact of a connector includes a wire pressing section 1, a plug-in connecting section 2 fixed to one side of the wire pressing section 1, and a threading hole opened on the other side of the wire pressing section 1. A mounting hole connected to the threading hole is opened on the top of the wire pressing section 1, and a clamping bolt 3 is threaded through the inner thread of the mounting hole;

[0021] When the wire clamping section 1 is to be connected to the wire, the stripped end of the wire is inserted into the threading hole in advance, and then the clamping bolt 3 is screwed into the installation hole so that the clamping bolt 3 clamps the stripped end of the wire, thereby achieving fixed installation of the wire in the threading hole.

[0022] Further, refer to Figure 1 and Figure 2 As shown, it is worth noting that it also includes a reinforcement mechanism arranged outside the threading hole;

[0023] The reinforcement mechanism includes a threaded sleeve 4 vertically fixed on the side wall of the wire compression section 1 and a plurality of compression rods 5 surrounding and fixed at the end of the threaded sleeve 4. An extrusion block 6 is fixed on the side of the end of the compression rod 5 facing the central axis of the threaded sleeve 4. An extrusion component is slidably arranged on the outer wall of the threaded sleeve 4.

[0024] The extrusion component includes a threaded sleeve 8 threadedly connected to the outer wall of the threaded sleeve 4 and a movable pressing sleeve 7 fixed to the side of the threaded sleeve 8 away from the wire pressing section 1. The inner cavity of the movable pressing sleeve 7 is truncated, and the side of the end of the pressure rod 5 away from the central axis of the threaded sleeve 4 is inclined and contacts the inner wall of the movable pressing sleeve 7.

[0025] Through the setting of the reinforcement mechanism, after the guide is inserted into the threading hole, the threaded sleeve 8 in the reinforcement mechanism is twisted toward the side of the wire clamping section 1, so that the movable compression sleeve 7 slides in the same direction as the threaded sleeve 8. In this way, the end of the pressure rod 5 is continuously squeezed and bent during the movement of the movable compression sleeve 7, and the extrusion block 6 contacts the outer wall of the wire to form pressure on the wire. In this way, the extrusion blocks 6 on several pressure rods 5 cooperate to compress the outer wall of the wire from multiple points outside the wire clamping section 1, thereby improving the connection strength between the wire and the wire clamping section 1, so as to prevent the wire from affecting the normal use of its front end stripping section when it is pulled.

[0026] Further, refer to Figure 2 and Figure 3 As shown, it is worth noting that it also includes a covering protection mechanism arranged on the wire pressing section 1;

[0027] The covering protection mechanism includes a covering sheet 9 slidably arranged on the top surface of the wire pressing section 1, the covering sheet 9 is located between the pressing bolt 3 and the threaded sleeve 8, and one side of the covering sheet 9 abuts against the threaded sleeve 8;

[0028] Through the setting of the covering and protecting mechanism, when the knob threaded sleeve 8 is turned toward the side of the wire clamping section 1, the threaded sleeve 8 can synchronously squeeze the covering piece 9, causing the covering piece 9 to slide on the wire clamping section 1 until the covering piece 9 moves to above the clamping bolt 3. The covering piece 9 can effectively cover and protect the clamping bolt 3 to prevent the clamping bolt 3 from being exposed to the outside for a long time and being easily affected by the environment and rusting.

[0029] Further, refer to Figure 3 As shown, it is worth noting that a slide groove 10 is symmetrically provided on the bottom surface of the cover sheet 9, a slider 11 fixedly connected to the top surface of the wire pressing section 1 is slidably provided in the slide groove 10, and a compression spring 12 is fixed between the slider 11 and the inner wall of one side of the slide groove 10;

[0030] Through the arrangement of the slider 11 and the compression spring 12, as shown above, when the threaded sleeve 8 squeezes the cover sheet 9 to slide, the slider 11 can slide inside the slide groove 10 and compress the compression spring 12 to deform. In this way, by utilizing the elastic force of the compression spring 12, when the threaded sleeve 8 is reversed to reduce the squeezing of the cover sheet 9, the cover sheet 9 can be quickly reset under the elastic force of the compression spring 12, which is convenient for secondary use.
