Description

Technical Field

[0001] The present invention relates to the technical field of distribution terminals, and in particular to an anti-misconnection device for distribution terminals. Background Art

[0002] With the development of the economy and the construction of smart electricity, the number of distribution terminals in the current distribution network is increasing day by day. The tail wiring of some terminals reaches as many as 10 roots, and the wiring times are numerous. Moreover, the quality of construction workers is uneven. Due to different bidding results, the personnel flow of terminals and electricity meters is also relatively large, and it is difficult to train and meet the requirements. As a result, wiring errors occur frequently, causing power loss to the power grid, incorrect collection by smart terminals, forming potential safety hazards, affecting customer service satisfaction. And currently, when wiring, the wire is usually directly tightened on the terminal wiring post through screws. When maintenance is required, the screws need to be turned back and forth, which is not only cumbersome to operate, prone to misconnection and missed connection, but also may cause the joint to loosen due to insufficient tightening, resulting in poor contact.

The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or selectively exclusive embodiments from other embodiments.

[0029] Embodiment 1

[0030] Referring to Figures 1 to 8 , which is the first embodiment of the present invention. This embodiment provides an anti-misconnection device for distribution terminals. The anti-misconnection device for distribution terminals includes a first docking unit 100 and a second docking unit 200, and the first docking unit 100 and the second docking unit 200 are in plug-in fit.

[0031] Specifically, the first docking unit 100 includes a first housing 101 and a first conductive member 102 fixed inside the first housing 101. First card slots 101a are symmetrically arranged on the first housing 101.

[0032] The second docking unit 200 includes a second housing 201, a first limiting member 202 disposed on the second housing 201 and cooperating with the first card slot 101a, and a second conductive member 203 cooperating with the first conductive member 102. The first docking unit 100 is connected to the power distribution terminal, and the second docking unit 200 is connected to the wire. During use, the first docking unit 100 and the second docking unit 200 can be directly docked.

[0033] The first limiting member 202 includes an upper baffle 202a, a lower baffle 202b, and an elastic member 202c. The upper baffle 202a includes an upper pressing plate 202a-1, a first side plate 202a-2 connected to the upper pressing plate 202a-1, and a first limiting plate 202a-3 connecting the two first side plates 202a-2. The first side plate 202a-2 is slidably engaged with the second housing 201, and the first limiting plate 202a-3 can cooperate with the first card slot 101a.

[0034] The lower baffle 202b includes a lower pressing plate 202b-1, a second side plate 202b-2 connected to the lower pressing plate 202b-1, and a second limiting plate 202b-3 connecting the two second side plates 202b-2. The second limiting plate 202b-3 is slidably engaged with the second housing 201, and the second limiting plate 202b-3 can cooperate with the first card slot 101a. The first limiting plate 202a-3 passes through the second side plate 202b-2, and a first moving slot 202b-21 cooperating with the first limiting plate 202a-3 is provided on the second side plate 202b-2.

[0035] Two sets of elastic members 202c are provided, respectively disposed between the lower pressing plate 202b-1 and the first limiting plate 202a-3, and between the upper baffle 202a and the first limiting plate 202a-3.

[0036] In this embodiment, the elastic member 202c is a sleeve rod, a sleeve, and a spring. The sleeve rod and the sleeve can slide relative to each other, and the spring is sleeved on the sleeve rod and the sleeve. The spring is a compression spring. When the first limiting strip 204c is not engaged with the first limiting plate 202a-3 or the second limiting plate 202b-3, the first limiting plate 202a-3 and the second limiting plate 202b-3 will be pressed tightly in the first card slot 101a under the action of the spring, so that the first docking unit 100 and the second docking unit 200 are engaged. When the lower pressing plate 202b-1 and the upper pressing plate 202a-1 are simultaneously pressed to the limit position, the first limiting plate 202a-3 and the second limiting plate 202b-3 will disengage from the first card slot 101a. At this time, the first docking unit 100 and the second docking unit 200 can be separated.

[0037] Further, the first docking unit 100 further includes a first engaging member 103 disposed at the end of the first housing 101 and rotatably engaged therewith. The second docking unit 200 further includes a second limiting member 204 disposed in the second housing 201 and cooperating with the first limiting member 202, and a third limiting member 205 cooperating with the second limiting member 204. The third limiting member 205 cooperates with the first engaging member 103.

[0038] A second moving groove 201a is provided in the second housing 201. The second limiting member 204 includes a first annular platform 204a disposed in the second moving groove 201a, a first spring 204b disposed in the second moving groove 201a and supporting the first annular platform 204a, and a first limiting strip 204c fixedly connected to the first annular platform 204a. A third moving groove 201b cooperating with the first limiting strip 204c is provided in the second housing 201. The end of the first limiting strip 204c can be engaged with the first limiting plate 202a-3 or the second limiting plate 202b-3. The first annular platform 204a can move in the second moving groove 201a. The first spring 204b is also a compression spring. When the first annular platform 204a is not subject to an external force, the first annular platform 204a will be pressed against the side wall of the second moving groove 201a by the first spring 204b. At this time, the two symmetrically arranged first limiting strips 204c can respectively engage the first limiting plate 202a-3 and the second limiting plate 202b-3, so that the upper pressing plate 202a-1 and the lower pressing plate 202b-1 cannot move. In this state, the first docking unit 100 and the second docking unit 200 can be easily inserted and no limiting will be formed.

[0039] Further, the second housing 201 includes a head housing N and a tail housing M. The third limiting member 205 includes a snap ring 205a connecting the head housing N and the tail housing M, a sleeve 205b disposed inside the head housing N, a flange 205c disposed at the end of the sleeve 205b, and a second limiting strip 205d fixedly connected to the flange 205c. A second card slot 103a cooperating with the second limiting strip 205d is provided on the first engaging member 103. The second moving groove 201a is provided in the head housing N. A limiting protrusion 205c-1 is provided on the side surface of the flange 205c. A limiting groove 204a-1 cooperating with the limiting protrusion 205c-1 is provided on the first annular platform 204a. When the first annular platform 204a is not subject to an external force, the limiting protrusion and the limiting groove 204a-1 cooperate with each other. At this time, the snap ring 205a cannot be rotated.

[0040] When the first docking unit 100 is inserted into the second docking unit 200, the first annular platform 204a on the first docking unit 100 will first come into contact with the second limiting strip 205d. If the second limiting strip 205d cannot be inserted into the second card slot 103a, the first docking unit 100 cannot be inserted further, and the two do not match, indicating that the wires are connected incorrectly. At this time, the conductive gasket 102c and the conductive post 203a are not connected, that is, a circuit cannot be formed and no impact will be caused. If the second limiting strip 205d can be inserted into the second card slot 103a, the first docking unit 100 continues to be inserted, then the end of the first docking unit 100 will squeeze the first annular platform 204a to make it move. At this time, the first annular platform 204a will drive the first limiting strip 204c to move. When the first docking unit 100 is inserted to the limit position, the first limiting strip 204c just disengages from the first limiting plate 202a-3 and the second limiting plate 202b-3, and the first limiting plate 202a-3 and the second limiting plate 202b-3 enter the first card slot 101a under the action of the elastic member 202c. Due to the elastic force, a "click" sound will be emitted, which can remind the staff that the docking has been completed at this time.

[0041] It should be noted that a bump K should be provided at the end of the first docking unit 100. This bump K can only come into contact with the first annular platform 204a and cannot come into contact with the flange 205c.

[0042] Furthermore, a first annular groove N-1 is provided on the head housing N, a second annular groove M-1 is provided on the tail housing M, engaging portions 205a-1 are provided at both ends of the snap ring 205a, and the two engaging portions 205a-1 cooperate with the first annular groove N-1 and the second annular groove M-1 respectively, and the snap ring 205a can rotate. The first conductive member 102 includes a first conductive sheet 102a extending out of the first housing 101, a conductive plate 102b connected to the first conductive sheet 102a, and a conductive gasket 102c provided at the end of the conductive plate 102b. The conductive gasket 102c is fixedly provided in the first housing 101. The first conductive sheet 102a is connected to the terminal of the power distribution terminal. The second conductive member 203 includes a conductive post 203a that can cooperate with the conductive gasket 102c, and a second conductive sheet 203b connected to the conductive post 203a. The wire is connected to the second conductive sheet 203b. Preferably, a fastening screw M-2 is further provided on the tail housing M to facilitate fixing the wire. A baffle 101b is provided on the first housing 101.

[0043] Preferably, an indication mark 205a-2 is provided on the snap ring 205a, and indication grooves N-2 are arranged in an array on the head housing N. When the first docking unit 100 and the second docking unit 200 cooperate with each other, at this time, the second limiting strip 205d is also inserted into the second card slot 103a. Therefore, rotating the snap ring 205a will drive the first engaging member 103 to rotate. The setting of the indication mark 205a-2 and the indication mark 205a-2 is to facilitate the distinction between multiple anti-misconnection devices. That is, after the first docking unit 100 and the second docking unit 200 are docked, the snap ring 205a can be rotated, and the rotation positions of the snap rings 205a of multiple anti-misconnection devices are all different. At this time, different anti-misconnection devices cannot match each other, effectively preventing the occurrence of miswiring.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
