With reference to fig. 1 and 2, an embodiment of the present disclosure provides a connection terminal, including: the terminal pressing plate 30, the terminal bottom plate 10 and at least two rib plates 20; at least one side wall of the terminal bottom plate 10 is bent and extended to form a mounting part 101 for fixing; at least two rib plates 20 are oppositely arranged on the peripheral side of the terminal bottom plate 10 and are vertical to the terminal bottom plate 10; the terminal base plate 10 and the rib plates 20 define an accommodating cavity 100 for accommodating the terminal pressing piece 30, and the inner side wall of at least one rib plate 20 is configured with a stopper 201 for limiting the terminal pressing piece 30 to slide out of the accommodating cavity 100.

By adopting the wiring terminal provided by the embodiment of the disclosure, the fixing of the terminal bottom plate 10 is realized through the mounting part 101, and the wiring terminal is prevented from falling off; the accommodating cavity 100 defined by the terminal bottom plate 10 and the rib plate 20 limits the installation space of the terminal pressing sheet 30, and the terminal pressing sheet 30 is prevented from falling off under the action of gravity when the wiring terminal is installed on a roof through the stopping part 201, so that the reliability of the wiring terminal in the construction process is improved, the working efficiency of construction is improved, and potential safety hazards are eliminated.

Here, "the side wall of the terminal bottom plate 10" can be understood as: in the case where the terminal bottom plate 10 is placed horizontally, the side surface of the terminal bottom plate 10 located on the vertical plane is a side wall. A part or the whole of the sidewall of the terminal bottom plate 10 is bent to extend a set length, thereby configuring to form the mounting portion 101. Alternatively, in the case where a partial region of the side wall of the terminal bottom plate 10 is bent and extended, the symmetrical dividing line of the mounting portion 101 and the symmetrical dividing line of the side wall of the terminal bottom plate 10 are located on the same straight line. Thus, the force between the mounting portion 101 and the terminal base plate 10 can be uniformly applied, and the stability of the terminal base plate 10 after mounting can be ensured.

The "peripheral side of the terminal base plate 10" can be understood as: the circumferential side surface of the terminal bottom plate 10. The rib 20 is disposed perpendicular to the terminal bottom plate 10, and the rib 20 is disposed on the circumferential side of the terminal bottom plate 10. Under the condition that the wiring terminal comprises two rib plates 20, the two rib plates 20 are oppositely arranged on two sides of the terminal bottom plate 10 and define an accommodating cavity 100 together with the terminal bottom plate 10; the terminal pressing sheet 30 is located in the accommodating cavity 100, the lead is located between the terminal pressing sheet 30 and the terminal base plate 10, the terminal pressing sheet 30 is fastened and connected with the terminal base plate 10 through the fastener 50, and the lead is not only contacted with the terminal pressing sheet 30, but also contacted with the terminal base plate 10, so that the wiring purpose of the wiring terminal is realized.

Alternatively, the terminal bottom plate 10 and the rib plate 20 are integrally formed. This saves mounting steps on the one hand and contributes to an increase in the reliability of the connection terminal on the other hand. Rib 20 has a certain toughness. In addition, the blocking portion 201 is located in the accommodating cavity 100. The stopping portion 201 may be in a shape of a dot, a block, or a strip. In practical applications, the terminal pressing sheet 30 can be placed into the receiving cavity 100 through the upper portion of the stopping portion 201. When the terminal pressing piece 30 is placed into the accommodating cavity 100 through the upper portion of the stopper 201, the rib plate 20 needs to be expanded in a direction away from the terminal bottom plate 10, then the terminal pressing piece 30 is placed in, an acting force applied to the rib plate 20 is released, the rib plate 20 is reset, and then the terminal pressing piece 30 is limited by the two rib plates 20 which are arranged oppositely. Under the condition that the terminal pressing sheet 30 is not connected with the terminal bottom plate 10, the stopping part 201 can prevent the terminal pressing sheet 30 from sliding out of the accommodating cavity 100, and the potential safety hazard caused by the sliding out of the accommodating cavity 100 is eliminated.

Optionally, the terminal pressing piece 30 is square, and the width of the terminal pressing piece 30 is smaller than the distance between two oppositely arranged rib plates 20.

The terminal pressing sheet 30 is connected with the terminal bottom plate 10 through screws, wherein friction force exists between the terminal pressing sheet 30 and the screws, the terminal pressing sheet 30 can easily rotate along with the screws under the condition that the screws are screwed, and at the moment, the terminal pressing sheet 30 can be limited to rotate through the inner side wall of the rib plate 20 under the condition that the terminal pressing sheet 30 is square, so that the fixing and limiting effects are achieved. In addition, the width of the terminal pressing piece 30 is smaller than the distance between the two oppositely arranged rib plates 20, so that the movable space of the terminal pressing piece 30 between the two oppositely arranged rib plates 20 can be ensured, that is, under the condition of adjusting the distance between the terminal pressing piece 30 and the terminal bottom plate 10, the terminal pressing piece 30 can not rub against the rib plates 20, and the loss is reduced.

In practical applications, the surface of the terminal wafer 30 that is projected to the maximum area is square. When the symmetrical dividing line of the terminal pressing piece 30 and the symmetrical line between the two rib plates 20 are located on the same straight line, the distance from the edge of the terminal pressing piece 30 to the rib plate 20 is smaller than the width of the terminal pressing piece 30. Thus, the rib 20 restricts the rotation of the terminal pressing piece 30 by the force from the screw.

Alternatively, in the case that the two rib plates 20 are oppositely arranged and both configured with the stoppers 201, the two stoppers 201 are oppositely arranged, and the width of the terminal pressing sheet 30 is greater than the distance between the two stoppers 201.

The two stoppers 201 can further more effectively prevent the terminal pressing piece 30 from falling off from the accommodating cavity 100. The width of the terminal pressing sheet 30 is greater than the distance between the two stopping portions 201 and less than the distance between the two opposite rib plates 20.

Optionally, the back stop 201 is integrally formed with the rib 20, or is removably attached to the rib 20. In the case that the back stop 201 is detachably connected to the rib plate 20, the back stop 201 may be detachably connected to the rib plate 20 by screws, or may be embedded in the rib plate 20. In the case that the stopping portion 201 is detachably connected to the rib plate 20, the stopping portion 201 may be mounted on the rib plate 20 after the terminal pressing sheet 30 is placed in the accommodating cavity 100. Thus, the loss of the rib 20 due to the pressing can be reduced.

Optionally, the stopping portion 201 is a wedge-shaped structure, wherein the inclined surface of the stopping portion 201 faces away from the terminal base plate 10.

Through backstop portion 201 that is the wedge structure for terminal preforming 30 is changeed along the inclined plane of backstop portion 201 and is got into holding chamber 100, helps reducing terminal preforming 30 in the installation, with backstop portion 201's friction, reduce the loss.

In practical application, the terminal bottom plate 10, the terminal pressing sheet 30 and the stopper portion 201 are sequentially arranged along a direction from bottom to top, and the inclined surface of the stopper portion 201 is inclined from the rib plate 20 to the terminal bottom plate 10 along the direction from top to bottom.

Optionally, the plane of rib 20 is perpendicular to the plane of mounting portion 101. In this way, when the terminal bottom plate 10 is mounted, the rib plate 20 and the mounting portion 101 can contribute to improvement in stability of the terminal bottom plate 10 in the circumferential direction of the terminal bottom plate 10. In practical applications, the terminal bottom plate 10 is a plate-shaped square structure, and includes a first side wall, a second side wall, a third side wall, and a fourth side wall, where the first side wall, the second side wall, the third side wall, and the fourth side wall form a circle, that is, the peripheral side of the terminal bottom plate 10. In the case where the two rib plates 20 are provided on the first side wall and the third side wall, respectively, the mounting portion 101 is provided on the second side wall or the fourth side wall. This contributes to improving the stability of the terminal bottom plate 10.

Alternatively, the mounting portion 101 is plate-shaped, and the side wall is configured with barbs 102 for reinforcing the fixing mounting portion 101. Thus, the barb 102 makes the installation of the installation part 101 more firm, and improves the stability of the installation part 101. Optionally, both oppositely disposed side walls of the mounting portion 101 are configured with barbs 102.

Alternatively, the barbs 102 are tooth-like projections formed by the mounting portion 101. Alternatively, the barb 102 is a wedge-shaped projection formed on the side wall of the mounting portion 101, wherein the inclined surface of the wedge-shaped projection faces outward.

Alternatively, the terminal bottom plate 10 includes a plurality of mounting portions 101, and at least two mounting portions 101 disposed oppositely.

The two oppositely disposed mounting portions 101 can improve the stability of the terminal bottom plate 10 during use after mounting. Alternatively, two oppositely disposed mounting portions 101 are symmetrically disposed. Thus, the stability of the mounting portion 101 can be further improved, and the mounting portion 101 can be uniformly stressed, so that loss is reduced.

Alternatively, the terminal bottom plate 10 includes a plurality of mounting portions 101, and includes at least three mounting portions 101 arranged in a triangular structure.

The three installation department 101 that are the triangle-shaped structure and lay through the triangle-shaped structure, helps promoting the stability after terminal bottom plate 10 installs, still can make three installation department 101 atress even simultaneously. Two installation departments 101 in the three installation department 101 that lay that are the triangle-shaped structure are the U type structure between, do not establish barb 102 on the lateral wall that two installation departments 101 are opposite, and barb 102 sets up in the outside of two installation departments 101. Thus, the mounting and dismounting of the terminal base plate 10 can be facilitated.

Optionally, the terminal bottom plate 10 is provided with a threaded hole, and the edge of the threaded hole is bent and extended to form a connecting portion 103 for enlarging the threaded connection length; wherein the connecting portion 103 and the mounting portion 101 are located on the same side of the terminal bottom plate 10.

In practical applications, the terminal base plate 10 and the terminal pressing plate 30 are connected by fasteners 50, such as: screws or bolts. The connection length of the terminal base plate 10 and the fastening member 50, that is, the firmness of the fastening member 50 and the terminal base plate 10 can be increased by the connection portion 103, thereby improving the stability of the terminal base plate 10 and the terminal pressing plate 30 after the wire connecting operation.

By locating the connecting portion 103 and the mounting portion 101 on the same side of the terminal base plate 10, it can be effectively avoided that the connecting portion 103 interferes with the installation of the wire or the terminal wafer 30 during the wiring process.

The terminal pressing piece 30 is provided with a through hole, a screw penetrates through the through hole of the terminal pressing piece 30, and the diameter of the through hole is larger than that of the screw threaded rod and smaller than that of the screw cap. For convenience of description, a portion of the screw near the nut is defined as an upper portion, and the other portion is defined as a lower portion. The upper part of the screw is a threaded rod, and the lower part of the screw is a polished rod. Wherein the length of the upper portion of the screw is greater than the total thickness of the terminal press piece 30, the wire and the terminal base. Thus, the terminal pressing piece 30 and the terminal base can be connected with each other while the screw tightening is satisfied. In addition, when the screw is loosened to a certain degree, because the lower part of the screw is a polished rod, under the condition that the threaded rod of the screw is separated from the thread of the terminal bottom plate 10, the screw can drive the terminal pressing plate 30 to automatically separate from the stopping part 201 under the action of gravity, and therefore the replacement or the withdrawal of the lead can be realized.

Optionally, the terminal base plate 10 is made of ABS plastic.

Optionally, the end of the mounting portion 101 facing away from the terminal bottom plate 10 is chamfered. In this way, the mounting of the terminal base plate 10 can be facilitated.

In the case where the rib plate 20 is vertically disposed, the bottom surface of the terminal bottom plate 10 is higher than the bottom surface of the rib plate 20. Thus, when the terminal bottom plate 10 is mounted, the terminal bottom plate 10 can be supported by the rib plate 20, and the stability of the terminal bottom plate 10 can be improved.
