Description

Technical Field

[0001] The utility model relates to the technical field of terminals, in particular to a bidirectional fixed circuit terminal structure. Background Art

[0002] The through-type two-way terminal block is used to facilitate the connection of wires. It is actually a piece of metal sheet sealed in insulating plastic. There are holes at both ends for inserting wires and screws for tightening or loosening. For example, two wires sometimes need to be connected and sometimes need to be disconnected. They can be connected with terminals and disconnected at any time without having to weld them or wrap them together. It is more convenient and quicker.

[0003] In order to prevent dust from entering the connection between the wire and the terminal, the existing through-type two-way terminal will install a dust cover on the terminal. However, in order to prevent the dust cover from affecting the terminal wiring, the dust cover will avoid the wiring side of the terminal, so that the wiring side of the terminal is in an open state. Dust will enter the connection between the wire and the terminal through the wiring side of the terminal, resulting in the dust-proof effect of the terminal is not thorough enough and needs to be improved.

[0020] 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 of 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.

[0021] Embodiment 1

[0022] See also Figure 1 , Figure 2 The figure shows a bidirectional fixed circuit terminal structure, including a terminal body 1, a plurality of screws 2 equidistantly distributed are respectively installed at the upper and lower ends of the terminal body 1, two rows of wires 3 are installed on the outside of the terminal body 1, and the wires 3 are fixedly connected to the terminal body 1 through the screws 2, and also includes a blocking component 4 for blocking the side of the screw 2 where the wire 3 is installed, and the blocking component 4 is installed on the outside of the wire 3; a dust cover 6 is used to block dust at the connection between the wire 3 and the terminal body 1, and the dust cover 6 is installed at the upper and lower ends of the terminal body 1.

[0023] See also Figure 3 The blocking component 4 includes a baffle 401, which is rectangular in shape. Insertion slots 5 are provided at both ends of the terminal body 1. The baffle 401 is plugged and unplugged with the terminal body 1 through the insertion slots 5. A plurality of elastic rubber rings 402 distributed at equal distances are fixedly embedded on the baffle 401. The inner wall of the elastic rubber ring 402 can fit tightly with the outer wall of the wire 3. The elastic rubber ring 402 is movably sleeved on the outer side of the wire 3. The inner diameter of the elastic rubber ring 402 is smaller than the outer diameter of the wire 3, and the inner diameter of the elastic rubber ring 402 can be changed.

[0024] See also Figure 4 Two rows of symmetrically distributed blocks 7 are fixedly installed on the inner side of the dust cover 6. The cross-sectional shape of the block 7 is semicircular, and the end face shape of the block 7 is semicircular, which can reduce the friction between it and the terminal body 1. Four card slots 8 symmetrically distributed in pairs are opened on the front and rear sides of the terminal body 1. The cross-sectional shape of the card slot 8 is equal to the cross-sectional shape of the block 7. The block 7 is movably connected with the terminal body 1 through the card slot 8.

[0025] The working principle of the good dust-proof effect of the bidirectional fixed circuit terminal structure: when assembling the wire 3 and the terminal body 1, the personnel first pass the end of the wire 3 through the inside of the elastic rubber ring 402. Since the inner diameter of the elastic rubber ring 402 is smaller than the outer diameter of the wire 3, the elastic rubber ring 402 will fit tightly against the outer wall of the wire 3. After adjusting the end length of the wire 3, the personnel insert the baffle 401 into the corresponding plug-in slot 5 on the terminal body 1, and then fix the end of the wire 3 to the terminal body 1 with the screw 2, and finally cover it with the dust cover 6. The dust cover 6 and the sealing assembly 4 together protect the connection between the wire 3 and the terminal body 1, which can effectively prevent dust from entering the connection between the wire 3 and the terminal body 1, so that the dust-proof effect of the terminal body 1 is better.

[0026] Embodiment 2

[0027] See also Figure 3 This embodiment further illustrates the first embodiment, that the number of the plug-in slots 5 provided at each end of the terminal body 1 is two groups, and they are symmetrically distributed.

[0028] In the present embodiment: since two symmetrically distributed plug-in slots 5 are provided at both the upper and lower ends of the terminal body 1, the baffle 401 is movably plugged into the terminal body 1 through the plug-in slots 5, so that the blocking component 4 can change its position according to the wiring situation of the terminal body 1, so that the terminal body 1 can be wired on the same side or on both sides, which is more flexible to use.

[0029] Embodiment 3

[0030] See also Figure 2 This embodiment further illustrates other embodiments, that the connection between the baffle 401 and the dust cover 6 is a movable abutment.

[0031] In this embodiment: when a person puts on the dust cover 6, a plurality of card blocks 7 on the inner side of the dust cover 6 are inserted into the card slots 8 on the terminal body 1. At this time, the upper end of the baffle 401 blocks the dust cover 6, thereby preventing the baffle 401 from detaching from the terminal body 1.
