Description

Terminal block {TERMINAL FRAME}

The present invention relates to a terminal block, and more particularly, to a terminal block in which a plug can be easily coupled and disconnected.

The terminal block in the present invention is used to detect a signal error by an operator when a signal error occurs in electrical components such as a power relay assembly (PRA) and a battery installed inside a vehicle. A plurality of female plugs are formed in the terminal block, and a circular male terminal such as a banana jack is inserted into the female plug. The operator can check the error of the control signal by inserting the banana jack into the female plug.

A conventional terminal block has a screw thread formed on the terminal block as in the attached prior art, and a bolt or nut is fastened to the lower end of the plug to be fixed to the terminal block. However, this fastening method has a problem in that the working speed becomes slower as the number of plugs to be assembled to the terminal block increases, and the space under the terminal block is narrow for the nut coupled to the lower end of the terminal block, so it is difficult to fasten.

In addition, since the conventional terminal block is formed by die casting metal, it is heavy and expensive, which is a major factor in the cost increase.

A locking end is protruded from the inner surface of the insertion hole and caught on the upper surface of the fixing head to prevent the plug from penetrating the insertion hole.

At least two or more fixed arms are formed, and the plurality of fixed arms are arranged at an angle.

A locking jaw protrudes from the fixing arm in a direction approaching each other to support the lower surface of the fixing head.

A guide slope is formed over the entire outer surface of the locking jaw from the tip of the fixed arm.

A guide portion is formed between the plurality of fixing arms to surround the outer surface of the fixing head.

The guide part is formed in a shape corresponding to the outer surface shape of the fixing head.

The locking end is formed to face each other and protrudes in a direction in which a pair approaches each other.

A pair of the plurality of fixing arms are formed to face each other.

The plate is formed by injection molding of a resin material.

The fixing arms are formed to be inclined at a predetermined angle in a direction to approach each other.

In the terminal block according to the present invention, the following effects can be obtained.

According to the present invention, since the terminal block is provided with a fixed arm having a guide slope, the plug can be coupled to the terminal block by simply pushing the plug into the insertion hole of the terminal block without a separate fastening device, thereby increasing work efficiency.

According to the present invention, since the guide portion surrounds the fixing head of the plug in the terminal block, the plug is prevented from being separated from the terminal block by vibration, thereby increasing the coupling stability between the plug and the terminal block.

In addition, a locking end is formed on the terminal block, and a locking jaw is formed on the fixed arm to prevent the plug from entering in the front-rear direction. Therefore, the coupling stability between the plug and the terminal block is increased by preventing the plug from being separated from the terminal block together with the guide part.

According to the present invention, the terminal block is formed of an injection material and is lighter than metal die-casting, and the cost is reduced and thus economical.

A preferred embodiment of the terminal block of the present invention will be described with reference to the accompanying drawings.

Referring to FIG. 1 , the plate 10 of the terminal block of this embodiment forms an exterior. The plate 10 has a flat plate shape. The plate 10 is made by injection molding of a resin material. The plate 10 is shown in a flat plate shape, but is not limited thereto, and may be integrally formed with a vehicle block or part of the exterior of an electric device in various shapes. The plug 20 is inserted into the plate 10 and fixed, and the operator can check the control information of the electrical equipment through the signal transmitted and received by inserting a terminal into the plug 20 .

On the other hand, the plug 20 is formed in a substantially cylindrical shape. A fixing head 21 having a larger diameter than that of the plug 20 is formed on one side of the plug 20 . As the fixing head 21 is fixed to the plate 10 , the plug 20 is supported on the plate 10 . A counter terminal is inserted through the fixing head 21 , and a wire is connected to the opposite side of the fixing head 21 to be electrically connected to the electrical equipment.

2 to 4 , an insertion hole 11 is formed in the plate 10 . The plug 20 is inserted through the insertion hole 11 and is connected to an external terminal. At least one insertion hole 11 is formed, and the number is formed differently according to the usage environment of the electrical equipment. The plug 20 is formed in a cylindrical shape, but the insertion hole 11 is not limited to a cross-sectional shape of the plug 20 . In this embodiment, the insertion hole 11 is formed in a rectangular shape in the plate 10 .

On the inner circumferential surface of the insertion hole 11 , a locking end 12 protrudes toward the center of the insertion hole 11 . The locking end 12 protrudes in a direction in which a pair faces each other and approaches each other. The locking end 12 is caught on one surface of the fixing head 21 of the plug 20 to prevent it from passing through the insertion hole 11 . However, since the locking end 12 should not interfere with the entry of the terminal inserted into the fixing head 21, it is preferable not to have an excessive amount of protrusion. It is preferable that at least two or more of the locking end 12 are formed so as to stably interfere with one surface of the fixing head 21 .

A fixing arm 13 protrudes from the plate 10 . The fixing arm 13 fixes the plug 20 inserted into the insertion hole 11 of the plate 10 . The fixing arm 13 has a cantilever shape extending to one side to be coupled to the plug 20 . A plurality of the fixing arms 13 may be disposed at an isometric angle. However, in this embodiment, the fixing arm 13 is formed to face each other as a pair. The fixing head 21 of the plug 20 elastically deforms the fixing arms 13 in a direction away from each other in the process of being inserted into the insertion hole 11, and the fixing head 21 is inserted into the insertion hole 11 ), the fixing arm 13 is released from deformation and is in close contact with the outer surface of the fixing head 21 . The fixing arms 13 may be formed to be inclined at a predetermined angle in a direction closer to each other in order to increase adhesion with the fixing head 21 .

A locking jaw 14 protrudes from the fixing arm 13 in a direction approaching each other. The locking protrusion 14 supports the step surface between the fixing head 21 and the plug 20 but is in close contact with the outer surface of the plug 20 to fix the plug 20 to the insertion hole 11 . . The locking protrusion 14 is hooked on the underside of the fixing head 21 to prevent the plug 20 inserted into the insertion hole 11 from being separated again in the direction in which it is coupled to the plate 10 .

A guide slope 15 is formed at the tip of the fixed arm 13 . Specifically, a guide slope 15 is formed over the entire outer surface of the locking jaw 14 from the tip of the fixing arm 13 . The guide slope 15 has an inclined surface formed from the tip of the fixing arm 13 toward the tip of the locking protrusion 14 . When the plug 20 is inserted into the insertion hole 11, the guide slope 15 induces the pair of fixing arms 13 to be elastically deformed smoothly in a direction away from each other.

A guide portion 16 protrudes from the plate 10 in a direction parallel to the fixing arm 13 . The guide part 16 is formed between the plurality of fixing arms 13 . The guide part 16 is formed to surround the side surface of the fixing head 21 to reduce vibration generated in the plug 20 . Since the guide part 16 surrounds the side surface of the fixing head 21 , it is preferable to have a shape corresponding to a portion of the outer surface of the fixing head 21 . In addition, the plug 20 is prevented from moving in the engaging direction by the engaging end 12 and the engaging protrusion 14, and is perpendicular to the engaging direction of the plug 20 by the guide unit 16 . movement in the direction is prevented. Accordingly, the plug 20 is completely fixed to the plate 10 by the locking end 12 , the locking jaw 14 and the guide part 16 .

Next, a process of assembling the plug 20 to the terminal block of this embodiment will be described.

The plug 20 is disposed so that the fixing head 21 faces the insertion hole 11 from the surface from which the fixing arm 13 of the plate 10 protrudes. When the fixing head 21 of the plug 20 moves toward the fixing arm 13 , the fixing head 21 comes into contact with the guide slope 15 of the fixing arm 13 . When the fixing head 21 continues to enter the insertion hole 11 while in contact with the guide slope 15 , the pair of fixing arms 13 move in the inclination direction of the guide slope 15 . is elastically deformed accordingly. That is, the pair of fixed arms 13 are elastically deformed in a direction away from each other.

When the fixing head 21 is stopped from moving by the locking end 12, the elastic deformation of the fixing arm 13 is released as shown in FIG. 5, and the locking jaw 14 is While supporting the bottom surface of the fixing head 21 , the tip of the locking protrusion 14 is in close contact with the outer surface of the plug 20 . That is, the locking protrusion 14 supports the step surface between the fixing head 21 and the plug 20 but is in close contact with the outer surface of the plug 20 to insert the plug 20 into the insertion hole 11 . and to prevent the plug 20 inserted into the insertion hole 11 from being separated again in the direction in which it is coupled to the plate 10 .

At the same time, the guide part 16 prevents movement in a direction perpendicular to the coupling direction of the plug 20 . Accordingly, the plug 20 is completely fixed to the plate 10 by the locking end 12 , the locking jaw 14 and the guide part 16 .
