Detailed Description

The following provides a more detailed description of the present invention with reference to the accompanying drawings and detailed description.

As shown in fig. 1 to 6, a connection terminal comprises a terminal base 2, wherein one or more mounting grooves 6 are formed in the terminal base, the openings of the mounting grooves face upwards and are arranged in parallel, and metal terminals 3 are mounted in the mounting grooves. Establish wiring needle 16 on metal terminal 1, the wiring needle can vertically go out the needle or transversely go out the needle in order to satisfy different customers' demand, then the wire hole that supplies the wiring needle to wear to establish is seted up to the below of mounting groove or one side of mounting groove.

The metal terminal 3 includes a wire pressing portion 4 formed by a spring plate relatively opened at one end, and a connecting portion 5 connected to the other end, i.e. the metal terminal is similar to a spring plate clip. A depression bar 1 is established to line ball portion top, and the depression bar rotates through slewing mechanism to be connected in the mounting groove, and first state and second state are established to depression bar 1, and when depression bar 1 was located first state, the depression bar erects in line ball portion top, and the depression bar shape cooperates in mounting groove upper end opening, and when depression bar 1 was located the second state, the depression bar lid was located on mounting groove 6. As shown in fig. 2, the rotating mechanism includes a rotating shaft 11 disposed on the side walls of the two sides of the mounting groove and extending outward, and slots 10 disposed on the two sides of the pressing rod and having downward openings, only the slots 10 can also realize the rotation of the rotating shaft 11, for optimizing the structure, lugs 8 are further respectively and convexly disposed on the outer sides of the two sides of the pressing rod, the slots 10 are disposed on the lugs, a rotating shaft hole 9 for inserting the rotating shaft is disposed at the bottom of the slots 10 in a communicating manner, and the rotating shaft 11 passes through the slots 10 and is inserted into the rotating shaft. When the pressure lever is installed, the pressure lever is directly inserted along the lug slot 10 only by keeping the pressure lever in a vertical state, which is very convenient.

The lower part of the pressure lever is provided with a cam surface, the upper part of the pressure lever is provided with a pressure handle 7, when the pressure lever is positioned in a first state, the pressure lever is vertically arranged above the pressure line part, the pressure line part 4 is in a relatively opened state, the pressure lever is rotated to move from the first state to a second state, the lower part of the pressure lever gradually presses down the pressure line part 4 through the cam surface until the pressure line part is pressed tightly, and the pressure lever is limited in the second state. As shown in fig. 3 and 4, the cam surface is provided with an inclined surface 14 matched with the surface of the metal terminal, the highest position of the cam surface is set as a locking point 13, the inclined surface is positioned behind the locking point, when the pressure lever moves from the first state to the second state, the cam surface bypasses the locking point 13 until the inclined surface 14 is attached to the surface of the metal terminal, and the upper surface of the metal terminal is inclined downwards from the connecting part to the wire pressing part. When the press rod is in the second state, the line pressing part 4 of the metal terminal generates a restoring force to the press rod 1, and due to the limitation of the rotating shaft and the rotating shaft hole or the slot, the metal terminal can not act on the press rod to enable the press rod to move upwards, but acts on the cam surface to enable the press rod to rotate. The cam surface cannot be rotated due to the complete contact and compression of the inclined surface 14 with the upper surface of the metal terminal and the relationship of the locking point 13 on the cam surface, and the plunger is held in the second state. In order to avoid the overpressure of the pressure lever, the tail end of the mounting groove is provided with a limiting piece 12, and after the pressure lever rotates to the second state, the tail end of the pressure lever is limited on the limiting piece 12.

Line ball 15 is established to the relative department that opens of crimping portion, can be according to the demand, adjusts the size of line ball mouth in order to match different cable sizes, and binding post has seted up the wiring mouth corresponding to line ball position, and the cable stretches into on the line ball mouth of crimping portion from the wiring mouth, then is compressed tightly.

The wire is stretched into the wire pressing part 4 of the metal terminal and then is compressed and locked by the pressing rod. The operation mode of the pressure lever 1 is simple, and the pressure lever can be rotated from a vertical first state to a second state covering the mounting groove. Because the lower end of the pressure lever is provided with the cam surface, the line pressing part is in a relatively open state in a first state, after the lead is placed in the pressure lever, the cam surface rotates correspondingly when the pressure lever is rotated, and in the rotating process, the cam surface gradually presses down the line pressing part until the line pressing part reaches a second state of the pressure lever and is limited in the second state. The limiting mode is that the inclined surface 14 on the cam surface is abutted against the surface of the metal terminal, and the inclined surface is positioned behind the highest locking point 13 of the cam surface, namely the pressing wire part can not pass through the locking point to recover by virtue of the self tension of the pressing wire part. The line ball portion of shell fragment is compressed tightly to the depression bar, keeps in this state, and because be the face contact, more even to the pressure of cable. In the rotation process of the pressure lever, the pressure lever is limited by the limiting sheet, so that the pressure lever is prevented from rotating over the head.

The depression bar rotates to be connected in the mounting groove, and its shape of own cooperates the mounting groove setting, and the depression bar compresses tightly just to locate the mounting groove as gland lid behind the line portion on, accomplishes dustproof function.

The utility model discloses a to line ball structure's improvement, as long as through stirring depression bar compression shell fragment, just possible locking cable effect, line ball easy operation, dependable performance moreover.
