Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 2 and 3, a terminal of a display according to the present invention includes a metal member 1 and a plastic member 2. The metal piece 1 is provided with an insertion groove 3 into which part of the plastic piece 2 is inserted. And the two ends of the metal piece 1 are also provided with clamping pieces 4 which are inserted into the circuit board, and the clamping pieces 4 are integrally connected with the metal piece 1.

Referring to fig. 2 and 3, the clip 4 includes an arc portion 8, an extension portion 5, and an insertion portion 7. One end of the arc-shaped part 8, which is far away from the connection of the extension part 5, is fixedly connected with the notch of the insertion groove 3. And arc portion 8 is compared in the design of closed angle, and the arc has the effect that the hand of protection staff is not stabbed by the closed angle. The arc-shaped part 8 is located outside the insertion groove 3, so that the clamping sheet 4 does not need to be deformed and bent, and the surfaces of the arc-shaped part 8, the extension part 5 and the insertion part 7, which are far away from the insertion groove 3, are flush with the outer surface of the metal piece 1. Insert portion 7 fixed connection is in the one end of extension 5 towards the circuit board, because extension 5 is located the outside of metalwork 1, when not accurate aligning insert portion 7 with the fluting on the wiring board, extension 5 and the tie point of insert portion 7 and the tie point between arc portion 8 and the extension 5 will receive the extrusion force, and compare in joint piece 4 in the background art, the utility model provides a there is not the bending part in the tie point of arc portion 8 and extension 5 and the tie point between extension 5 and the insert portion 7, and this has strengthened the anti deformability of whole joint piece 4 for joint piece 4 is difficult for taking place to damage, has the effect that promotes joint piece 4 life. The end of the insertion part 7 inserted into the wiring board is also provided with an arc end 9, the arc end 9 has the function of guiding the insertion part 7 to be inserted into the groove formed on the wiring board, and even if part of the entity of the insertion part 7 is not inserted into the groove formed on the wiring board, the insertion part 7 can slide into the groove formed on the wiring board through the design of the arc end 9.

Referring to fig. 2 and 3, a recessed groove 10 is formed in one end of the extension portion 5 in the direction from the plastic piece 2 to the insertion groove 3, a clamping block 11 arranged in the recessed groove 10 is fixedly connected to the upper frame body, and the clamping block 11 is in contact with the extension portion 5. Under the effect of joint piece 11 for extension 5 is difficult to take place to the direction of keeping away from insertion groove 3 and is out of shape, when extension 5 takes place to the direction of keeping away from insertion groove 3 and deforms, still need overcome the extrusion force that comes from joint piece 11 to extension 5. And there is a space between the extension part 5 and the metal piece 1, and the worker can push the extension part 5 to move the extension part 5 towards the direction close to the insertion groove 3, so as to properly reduce the distance between the two extension parts 5, and facilitate the insertion part 7 to be inserted into the groove opened on the circuit board.

Referring to fig. 2 and 3, the extension 5 is wider than the insertion portion 7. After the insertion portion 7 passes through the circuit board, the lower end of the extension portion 5 contacts with the upper end face of the circuit board, and the extension portion 5 is always located above the circuit board. The extension part 5 is used for limiting the insertion part 7, so that the insertion part 7 is prevented from excessively penetrating through a circuit board, and the probability of damage of the insertion part 7 to other components is reduced.

Referring to fig. 2 and 3, heat dissipation grooves 12 are further formed at both ends of the metal fitting 1 to which the clip 4 is connected, and the heat dissipation grooves 12 are disposed to be offset from the clip 4. When the wiring terminal works, heat generated by the wiring terminal can be dissipated from the heat dissipation groove 12, so that the heat inside the metal piece 1 is not easy to accumulate, and the service life of the clamping sheet 4 is prolonged.

The implementation principle of the embodiment is as follows: the insertion part 7 is inserted into the circuit board until the lower end face of the extension part 5 contacts with the circuit board, at this time, the insertion part 7 is explained to move to the limit position towards the circuit board, and the surfaces of the arc part 8, the extension part 5 and the insertion part 7 are flush with the outer surface of the metal piece 1, so that the clamping sheet 4 is not easy to damage, and the service life of the clamping sheet 4 is prolonged.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
