Description

Technical Field

[0001] The technical solution relates to the technical field of wiring accessories, and in particular to a wiring terminal. Background Art

[0002] A terminal block is an electronic component used to connect wires or cables.

[0003] For example, a Chinese terminal block with patent announcement number CN203826588U includes a wiring portion for clamping a wire and a plug-in portion for plugging into a plug-in, including side panels, which are divided into left and right side panels. The left and right side panels can be bent toward each other to form a wiring cavity, and the side panels on both sides are respectively provided with protrusions and openings that fit together with the protrusions. The side panels on both sides can be bent toward each other and the protrusions are connected with the openings after bending. The protrusions are elastic sheets, and the shape of the elastic sheets is U-shaped, which contacts and cooperates with the two sides of the plug-in through the U-shaped structure.

[0004] The existing wiring terminals in the water pump driver are connection contacts with point contacts on both sides. After being plugged in, electric sparks may be generated under high load conditions, which has poor safety and needs to be improved. Summary of the invention

[0005] In order to improve the problem of poor plugging safety of wiring terminals, the present technical solution provides a wiring terminal.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A terminal block includes a terminal block, the terminal block is provided with a clip mechanism, the clip mechanism includes a first spring piece and a second contact piece, a plug-in channel is formed between the first spring piece and the second contact piece, the plug-in channel is used for inserting the plug-in piece, the second contact piece has a contact surface, the first spring piece is bent toward the contact surface to form a resistance portion, the elastic force of the first spring piece is used to press the plug-in piece against the contact surface so that the plug-in piece and the contact surface form a surface contact.

[0008] Through the above technical solution, when the terminal block is used normally, the plug is accurately inserted into the plug-in channel, and the clamping mechanism of the terminal block clamps the plug. At this time, the first spring sheet and the second contact sheet are respectively located on both sides of the plug. Based on the fact that the first spring sheet has a certain elastic force, it can be suitable for plugs of different thicknesses and specifications, thereby improving applicability.

[0009] The elastic force of the first spring sheet causes the plug to tend to press against the contact surface of the second contact sheet, so that the plug can stably form surface contact with the contact surface when moving in the plug, avoiding the risk of electrical failure caused by point contact or poor line contact, expanding the contact area and increasing the stability of the contact, thereby improving the safety of the plug.

[0010] Preferably, the span distance of the contact surface along the plugging direction with the plug piece is greater than or equal to 3.5 mm.

[0011] Through the above technical solution, the span distance of the contact surface along the plug-in direction is limited to a range greater than or equal to 3.5 mm, so that the span distance of the contact surface is larger, and a larger contact area can be left between the plug and the contact surface, which helps to disperse the current, reduce the contact resistance, and further improve safety.

[0012] Preferably, the terminal block has a plug-in piece, and the plug-in piece is used for plugging and leading out.

[0013] Through the above technical solution, the plug-in piece extends toward the side away from the clip mechanism, and the plug-in piece is plugged in to realize the quick connection between the wiring terminal and the external circuit or equipment to cooperate with the gasket for electrical conduction.

[0014] Preferably, the first spring piece has an inclined surface 1, which is inclined outwardly away from the terminal block, and the second contact piece has an inclined surface 2, the inclination direction of the inclined surface 2 is opposite to the inclined surface 1, and the inclined surface 2 cooperates with the inclined surface 1 so that the plug-in channel is flared outwardly away from the terminal block.

[0015] Through the above technical solution, the inclined surface 1 of the first spring piece and the inclined surface 2 of the second connecting piece are inclined outward in opposite directions, so that the connection channel is flared outward away from the terminal block, and the plug is inserted into the plug-in channel through the flared opening so that the plug is guided and positioned to the correct position, thereby reducing error deviation and improving the accuracy and reliability of plug-in docking.

[0016] Preferably, a joint seam is formed on the terminal block, and the terminal block has an anti-detachment spring sheet, the anti-detachment spring sheet is located on a side of the terminal block away from the joint seam, and the anti-detachment spring sheet is used to form an abutment.

[0017] Through the above technical solution, the terminal block is formed by bending a whole piece of material, so that the terminal block has a splicing seam, without the need for additional assembly steps, thereby reducing production costs, reducing potential loose points in the structure, and enhancing the stability of the structure. The terminal block at the splicing seam is easy to bend, and the anti-detachment spring sheet is fixed to the side of the terminal block away from the splicing seam to ensure that the connection position of the anti-detachment spring sheet has a higher strength. When the terminal block is installed, the anti-detachment spring sheet deforms and resists to form a stable positioning, thereby improving the installation stability of the terminal block.

[0018] Preferably, the terminal block is provided with a clearance groove, and the clearance groove is adapted to the anti-dropout spring sheet. When the terminal block is fitted, the anti-dropout spring sheet is embedded in the clearance groove to provide clearance.

[0019] Through the above technical solution, the anti-dropout spring sheet is adapted to the clearance groove, and the existence of the clearance groove provides necessary clearance space for the anti-dropout spring sheet, ensuring that during the fitting or installation process of the terminal block, the anti-dropout spring sheet is embedded in the clearance groove so that the anti-dropout spring sheet can pass smoothly without being obstructed or squeezed, thereby ensuring normal installation.

[0020] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:

[0021] 1. The technical solution is provided with a clamping mechanism on the terminal block, the clamping mechanism clamps the plug-in, the first spring sheet and the second contact sheet are respectively located on both sides of the plug-in, and the elastic force of the first spring sheet makes the plug-in have a tendency to press against the contact surface, so that the plug-in can stably form a surface contact with the contact surface when moving in the plug-in, thereby improving the plug-in safety;

[0022] 2. In this technical solution, the terminal block has an anti-detachment spring sheet, which is located on the side of the terminal block away from the joint. When the terminal block is installed, the anti-detachment spring sheet deforms and resists to form a stable positioning, thereby improving the installation stability of the terminal block.

DETAILED DESCRIPTION

[0027] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0028] Example:

[0029] See also Figure 1A terminal block includes a terminal block 1, which is formed by bending a whole piece of material. The terminal block 1 is bent to form a joint seam 9, which is located on the side wall relative to the terminal block 1 and is arranged along the length direction of the terminal block 1. The terminal block 1 has a plug-in piece 6, which is fixed to the side wall at one end of the terminal block 1 and is located at the lower end relative to the terminal block 1. The plug-in piece 6 extends in a direction away from the terminal block 1, and the plug-in piece 6 is used for plug connection.

[0030] The terminal block 1 is provided with a clamping mechanism 2, which includes a first spring piece 21 and a second contact piece 22. The first spring piece 21 and the second contact piece 22 are both located on the end surface of the terminal block 1 away from the plug-in piece 6. The first spring piece 21 and the second contact piece 22 are both fixed to the terminal block 1 in an integral manner at the corresponding end surfaces. The position of the second contact piece 22 is located at the lower end relative to the first spring piece 21. The second contact piece 22 corresponds to the plug-in piece 6 and extends in opposite directions. A plug-in channel 3 is formed between the first spring piece 21 and the second contact piece 22, and the plug-in piece is correspondingly inserted into the plug-in channel 3.

[0031] See also Figure 2 and Figure 3 The second contact piece 22 has a contact surface 4, which is located on the end surface of the second contact piece 22 facing the first elastic piece 21. The span distance of the contact surface 4 along the plug-in direction with the plug is greater than or equal to 3.5 mm. This example shows the case where the span distance of the contact surface 4 is 3.5 mm. The first elastic piece 21 is bent toward the contact surface 4 to form a resistance portion 5. The first elastic piece 21 has the ability of elastic deformation. The elastic force of the first elastic piece 21 makes the resistance portion 5 press against the plug, so that the plug has a tendency to press against the contact surface 4, thereby making the plug and the contact surface 4 form a surface contact.

[0032] The first spring piece 21 has an inclined surface 7, which is located at an end of the first spring piece 21 away from the terminal block 1, and the end surface of the inclined surface 7 faces the second contact piece 22, and the inclined surface 7 is inclined outward in the direction away from the terminal block 1. The second contact piece 22 has an inclined surface 28, and the inclined surface 28 is opposite to the inclined surface 17. The inclination direction of the inclined surface 28 is inclined outward relative to the inclined surface 17. The inclined surface 28 cooperates with the inclined surface 17 to make the plug-in channel 3 expand outward away from the terminal block 1.

[0033] The terminal block 1 has an anti-slip spring sheet 10, which is located on the side of the terminal block 1 away from the splicing seam 9. The anti-slip spring sheet 10 is used to form an interference positioning. The terminal block 1 is provided with a clearance groove 11, and the position of the clearance groove 11 is set corresponding to the anti-slip spring sheet 10. The clearance groove 11 is adapted to the anti-slip spring sheet 10. One end of the anti-slip single piece is embedded in the groove wall of the clearance groove 11 away from the side of the clamping mechanism 2. When the terminal block 1 is embedded, the anti-slip spring sheet 10 is embedded in the clearance groove 11 to provide clearance.

[0034] The specific working process of this program is as follows:

[0035] After the terminal block 1 is installed through the technical solution, the anti-drop spring sheet 10 is used to form an abutment positioning, and the plug-in piece is accurately inserted into the plug-in channel 3. The clamping mechanism 2 clamps the plug-in piece. The elastic force of the first spring sheet 21 makes the abutment portion 5 press against the plug-in piece, so that the plug-in piece has a tendency to press against the contact surface 4 of the second contact piece 22. When the plug-in piece moves in the plug-in, it can stably form a surface contact with the contact surface 4, avoiding the risk of electrical failure caused by point contact or poor line contact, expanding the contact surface 4 area to increase the stability of the contact, thereby improving the plug-in safety.
