Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to fig. 1 to 6 in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any new effort, are within the scope of the utility model.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "top", "bottom", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the position or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, are not to be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Referring to fig. 1 to 3, a first aspect of the present invention provides a connection terminal 100, which is used to detect whether cable connection is reliable, so as to avoid a situation that the connection terminal 100 is damaged due to serious terminal heating caused by unreliable cable connection.

Specifically, the connection terminal 100 includes a base 101, a first connection member 102 and a first connection detection device 103, wherein the base 101 is made of an insulating material, and the specific shape is not limited and can be set to any shape as required.

The base 101 has at least 2 first mounting cavities 101a, and the number of the first mounting cavities 101a is the same as the number of phases of the terminal 100, and may be at least 2 phases or 3 phases. In order to improve the wiring safety, the first installation cavities 101a are arranged in an isolation mode, so that an operator is prevented from touching the first cables in the other first installation cavity 101a by hands when one first installation cavity 101a is wired.

Adjacent first mounting cavities 101a are directly separated by a first insulating plate 101b disposed on the base 101, and the first insulating plate 101b is integrally formed with or bonded to the base 101, and the specific connection manner is not limited.

In order to facilitate the base 101 to be fixed on the box body to be connected, the utility model discloses that the base 101 is provided with a threaded hole which is in threaded connection with the box body to be connected.

First wiring installation positions 101a-1 are arranged in the first installation cavity 101a at intervals, and first wiring pieces 102 are installed on the first wiring installation positions 101a-1 so as to be electrically connected with first cables in a wiring mode.

In order to reduce the cross-sectional area of a single first cable, the utility model discloses that the number of the first wiring installation positions 101a-1 in the first installation cavity 101a is at least 2. The utility model reduces the cross section area of a single cable, and avoids the problem that the existing cable can not meet the use requirement due to the increase of current and the thick diameter of the required cable.

The first wiring pieces 102 on the first wiring installation positions 101a-1 in the same first installation cavity 101a are arranged at certain intervals, so that wiring of each first cable is facilitated.

The first wiring piece 102 and the first wiring installation position 101a-1 are arranged in a one-to-one correspondence mode, specifically, the first wiring piece 102 is a wiring nut column or a wiring screw and the like, a first copper bar 101a-2 is arranged on the first wiring installation position 101a-1, and the first wiring piece 102 is connected with the first copper bar 101 a-2.

The first wiring detection device 103 is used for detecting wiring between the first wiring piece 102 and the first cable, namely, wiring reliability detection, so that reliability detection of wiring of the wiring terminal 100 is realized, and the situation that the wiring terminal 100 is heated and the wiring terminal 100 is damaged due to unreliable connection is avoided.

In some embodiments, the first wire detection device 103 includes a plurality of first temperature detectors mounted on the base 101.

The first wiring installation positions 101a-1 in the first installation cavity 101a are arranged in a layered mode, and the heights of the first wiring installation positions 101a-1 of adjacent layers are different or the same. Here, the height is set in the direction of fig. 1, and is only for convenience of description, and does not have any other specific meaning. The layering arrangement is not limited to the upper and lower layers stacked in the height direction, but may be layers sequentially arranged in the horizontal direction, and the layering conditions in different first mounting cavities 101a are the same.

In order to facilitate the wiring of the adjacent first wiring installation positions 101a-1 in the same first installation cavity 101a, taking the difference in height between the adjacent first wiring installation positions 101a-1 as an example, as shown in fig. 1, the adjacent first wiring installation positions 101a-1 are distributed in a step shape.

The plurality of first temperature detectors are respectively configured to detect a temperature in each first mounting cavity 101a, and specifically, at least 1 first temperature detector is respectively installed corresponding to each first mounting cavity 101a to respectively detect a temperature of each first mounting cavity 101 a. Taking the example of arranging 1 first temperature detector corresponding to each first mounting cavity 101a, the first temperature detectors are all mounted at the end of each first mounting cavity 101a, and when the temperature detected by at least 1 first temperature detector is out of the preset temperature range value or the temperature difference detected by at least 2 first temperature detectors is greater than the temperature limit value, it is determined that the wiring terminal 100 has the condition of unreliable connection. The preset temperature range value and the temperature limit value are set according to requirements and are not limited to a certain specific value or specific values.

The first temperature detectors are not limited to detecting the temperature of each first mounting cavity 101a, and may be mounted on the base 101 at positions corresponding to the first wiring mounting locations 101a-1 of each layer to detect the temperature of the first wiring mounting locations 101a-1 of each layer. When the temperature detected by at least 1 first temperature detector is out of the preset temperature range value or the temperature difference detected by at least 2 first temperature detectors is greater than the temperature limit value, the situation that the wiring of the wiring terminal 100 is not reliably connected is judged.

Of course, a first temperature detector may be disposed at the position of each first wire installation position 101a-1 to detect the temperature of each first wire installation position 101a-1, and with this arrangement, it can be accurately determined which first wire member 102 at the first wire installation position 101a-1 is reliably connected to the first cable.

Specifically, the first temperature detector is a thermocouple or a thermal resistor, and is in signal connection with the controller, so that the controller can determine whether there is a temperature abnormality.

In order to facilitate finding out the situation that the wiring is not reliably connected in time, the utility model discloses that the first wiring detection device 103 further comprises a first alarm, and the first alarm is in signal connection with the controller. Specifically, the first alarm is an audible alarm, a light alarm or an audible and visual alarm.

In other embodiments, the first wiring detecting device 103 includes a first current detecting device and a second shorting member 105b, the first shorting members correspond to the first mounting cavities 101a one to one, and the first shorting members respectively short each first wiring member 102 in the same first mounting cavity 101 a. Specifically, the first short-circuit member is a copper bar, it should be noted that the first short-circuit member is a copper bar only as one specific embodiment of the present invention, and in practical application, the first short-circuit member may also be another metal bar.

The first current detection device is sequentially sleeved outside each first short-circuit piece and is electrically connected with the first short-circuit pieces for detecting current difference values. Taking the detection of three-phase power as an example, when the current detected by the first current detection device is 0, the situation that wiring is unreliable does not exist; when the current detected by the first current detection means is not 0, it indicates that there is a case where the wiring is not reliable. Of course, it can be understood that the first current detection devices may also be used to separately detect current values on the first short-circuit pieces, and determine whether the connection is unreliable by determining a current difference value on each first short-circuit piece.

Taking the connection terminal 100 as a wall-through terminal as an example, in view of safety issues, when the first connection detection device 103 includes a first current detection device and a second short-circuit piece 105b, the first installation cavity 101a is located in the box body to be connected, that is, the first cable is an internal cable for connecting electrical components in the box body to be connected; when the first connection detecting device 103 includes the first temperature detector, the first installation cavity 101a is located inside or outside the box to be connected, taking installation outside the box to be connected as an example, that is, the first cable is an external cable.

Further, the present invention discloses that adjacent first wiring pieces 102 in the same first mounting cavity 101a are arranged back to back. The back-to-back arrangement between adjacent first wire members 102 facilitates wiring. The back-to-back arrangement herein means that the terminals of the first wire member 102 for connecting the first cable are distant from each other.

In some embodiments, the base 101 further has a predetermined number of second mounting cavities 101 c. In order to improve the wiring safety, the second installation cavities 101c are arranged in an isolation mode, so that an operator is prevented from touching the second cables in the other second installation cavity 101c when wiring is conducted in one second installation cavity 101 c.

Specifically, adjacent second mounting cavities 101c are separated by a second insulating plate 101d, and the second insulating plate 101d is integrally connected with the base 101 by molding or bonding, and the specific connection manner is not limited.

As shown in fig. 2, the connection terminal 100 further includes second connection pieces 104, and the second connection pieces 104 are respectively mounted on the second connection mounting sites 101c-1 to be electrically connected to the first connection pieces 102 in the first mounting cavities 101a, respectively. The second wire member 104 is used to wire electrically connect the second cable.

Namely, the first wiring member 102 in the first mounting cavity 101a and the second wiring member 104 in the second mounting cavity 101c, one serves as a current input terminal of the wiring terminal 100, and the other serves as a current output terminal of the wiring terminal 100.

In some embodiments, as shown in fig. 4-6, the wire connecting terminal 100 further includes a second wire detection device 105, and the second wire detection device 105 is used for detecting the wire connection between the second wire member 104 and the second cable, so as to further improve the accuracy of detecting the reliable connection between the wire connecting terminal 100 and the cable or the like.

In some embodiments, the second wire detection device 105 includes a plurality of second temperature detectors mounted on the base 101.

The number of the second wiring installation positions 101c-1 in the second installation cavity 101c is at least 2, the second wiring installation positions are arranged at intervals in a layered mode, the second wiring pieces 104 are arranged in one-to-one correspondence with the second wiring installation positions 101c-1, specifically, the second wiring pieces 104 are wiring nut columns or wiring screws and the like, second copper bars are arranged on the second wiring installation positions 101c-1, and the second wiring pieces 104 are connected with the second copper bars.

The heights of the second wiring installation positions 101c-1 of adjacent layers are different or the same. In order to facilitate the wiring of the adjacent second wiring installation positions 101c-1 in the same second installation cavity 101c, taking the difference in height of the adjacent second wiring installation positions 101c-1 as an example, the adjacent second wiring installation positions 101c-1 are distributed in a step shape.

Specifically, at least 1 second temperature detector is respectively installed corresponding to each second mounting cavity 101c to respectively detect the temperature of each second mounting cavity 101 c. Taking the example of providing 1 second temperature detector corresponding to each second mounting cavity 101c, the second temperature detectors are all mounted at the end of each second mounting cavity 101c, and when the temperature detected by at least 1 second temperature detector is out of the preset temperature range value or the temperature difference detected by at least 2 second temperature detectors is greater than the temperature limit value, it is determined that the wiring terminal 100 has a condition that the wiring is not reliably connected.

The second temperature detector is not limited to detecting the temperature of each second mounting cavity 101c, and may be mounted on the base 101 at a position corresponding to each second wire mounting position 101c-1 to detect the temperature of each second wire mounting position 101 c-1. When the temperature detected by at least 1 second temperature detector is out of the preset temperature range or the temperature difference detected by at least 2 second temperature detectors is greater than the temperature limit value, it is determined that the wiring terminal 100 has the condition that the wiring is not reliably connected.

Of course, a second temperature detector may be disposed at the position of each second wire installation position 101c-1 to detect the temperature of each second wire installation position 101c-1, and with this arrangement, it can be accurately determined which second wire member 104 at the second wire installation position 101c-1 is not reliably connected with the cable.

Specifically, the second temperature detector is a thermocouple or a thermal resistor, and is in signal connection with the controller, so that the controller can determine whether there is a temperature abnormality.

In order to facilitate finding the situation that the wiring is not reliably connected in time, the utility model discloses that the second wiring detection device 105 further comprises a second alarm, and the second alarm is in signal connection with the controller. Specifically, the second alarm is an audible alarm, a light alarm, an audible and visual alarm or the like.

In other embodiments, the second wire detection device 105 includes a second current detection device 105a and a second shorting member 105 b.

The second short connecting pieces 105b correspond to the second installation cavities 101c one by one, and the number of the second wiring installation positions 101c-1 in the second installation cavities 101c is at least 2, and the second wiring installation positions are arranged at intervals. The second shorting member 105b is respectively shorted with each second wiring member 104 in the same second mounting cavity 101c, specifically, the second shorting member 105b is a copper bar, it should be noted that the second shorting member 105b is a copper bar is only a specific embodiment of the present invention, and in practical applications, the second shorting member 105b may also be set as other metal bars, etc.

The second current detection devices 105a are sequentially sleeved outside the second short-circuit pieces 105b, and are electrically connected with the second short-circuit pieces 105b for detecting current difference values. Taking the example of detecting three-phase power, when the current detected by the second current detection device 105a is 0, it indicates that there is no unreliable wiring; when the current detected by the second current detecting means 105a is not 0, it indicates that there is a case where the wiring is not reliable. Of course, it is understood that the second current detecting device 105a may detect the current value of each second short-circuit device 105b individually, and determine whether there is a connection failure by determining the current difference value of each second short-circuit device 105 b.

Taking the connection terminal 100 as a through-wall terminal as an example, in view of safety issues, when the second connection detection device 105 includes a second current detection device 105a and a second short-circuit piece 105b, the second installation cavity 101c is located in the box body to be connected; when the second wiring detecting device 105 includes the second temperature detector, the second mounting cavity 101c may be located inside or outside the box to be connected.
