Description

Technical Field

[0001] The utility model relates to the field of circuit wiring terminals, in particular to a threadless quick wiring terminal. Background Technique

[0002] A wiring terminal is a commonly used accessory product in an electronic circuit. The wiring terminal is to insert a wire into a flat guide socket and then use a screw for fixed connection.

[0003] CN201821784934.9 discloses a threadless quick wiring terminal, including a card seat and an elastic card. The elastic card is installed inside the card seat. An integrally formed buckle is connected above the elastic card. A limiting block is integrally formed inside the card seat. The buckle is clamped inside the limiting block. A flat wire socket is opened above the card seat. A guiding inlet is provided between the lower part of the elastic card and the bottom end inside the card seat. Guiding pressure grooves are provided on both sides of the lower part of the elastic card.

[0004] In this technical solution, the elastic card is used to limit the wire. Although the wire can be fixed, this fixing method is very unreliable. When installing a smooth wire, the wire will also come out from inside it. Moreover, when the wire is shaken, the probability of disconnection between the two will increase greatly. Content of the Utility Model

[0005] (I) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the utility model provides a threadless quick wiring terminal, which solves the problems put forward in the background technique.

[0007] (II) Technical Solutions

[0008] To achieve the above object, the utility model is realized through the following technical solutions: A threadless quick wiring terminal includes a housing. Two wire clamping components are arranged inside the housing. Terminals A and B are respectively fixed at one ends of the two wire clamping components close to each other. Terminal A and terminal B can be inserted and cooperatively fixed. The wire clamping component includes a first V-shaped plate, a second V-shaped plate and a clamping plate. Both the first V-shaped plate and the second V-shaped plate can elastically deform. The first V-shaped plate is inside the housing, and the housing corresponds to the position of the first V-shaped plate and matches its shape. When the first V-shaped plate moves towards the inside of the housing, it can be squeezed and closed by the housing. There are two second V-shaped plates, which are respectively fixed to the two ends of the first V-shaped plate. The ends of the two second V-shaped plates away from the first V-shaped plate are close to each other. Wire grooves are opened at one ends of the two second V-shaped plates close to each other. There are two groups of clamping plates, which are respectively fixed on the surfaces of the two second V-shaped plates close to each other. The clamping plates are inclined towards the inside of the housing, and an arc-shaped groove is opened at one end of the clamping plate away from the second V-shaped plate.

[0009] Preferably, the two ends of the second V-shaped plate that are away from each other respectively correspond to the upper and lower inner walls of the housing. Ratchet teeth are fixed on both the second V-shaped plate and the inner wall of the housing, and the ratchet teeth of the two are arranged in cooperation. The second V-shaped plate can move into the housing and is prevented from coming out by the resistance of the ratchet teeth.

[0010] Preferably, the terminal A includes a sleeve and a V-shaped cover. The sleeve is fixed to any one of the first V-shaped plates, and the V-shaped cover is located inside the sleeve with its open end facing outward.

[0011] Preferably, the terminal B includes a base and a hollow cone. The base is fixed to the other first V-shaped plate, and the hollow cone is fixed on the base with its tip facing outward. The hollow cone cooperates with the V-shaped cover, and the two can be fixed after being inserted.

[0012] Preferably, the middle positions at the upper and lower ends of the housing are both groove-shaped structures, and the sides of the groove-shaped structures are all inclined surfaces. The inclined surfaces cooperate with the inclined surfaces of the first V-shaped plates, and screws are installed at the positions of the inclined surfaces. The screws are threadedly connected to the housing, and one end of the screw can pass through the housing and contact the first V-shaped plate.

[0013] Preferably, a plurality of groups of heat dissipation grooves are provided on the housing.

[0014] (III) Beneficial effects

[0015] The present utility model provides a threadless quick connection terminal, which has the following beneficial effects:

[0016] 1. For this threadless quick connection terminal, the first V-shaped plate and the second V-shaped plate are provided. When the cable is inserted, since one end of the two second V-shaped plates is close to each other and a clamping plate is provided at the position where they are close to each other, the resistance of the cable during insertion is small. However, as the cable is inserted, the cable will also be clamped by the two second V-shaped plates. At the same time, the clamping plate can prevent the cable from coming out. When continuous pressure is applied, the first V-shaped plate drives the two second V-shaped plates to penetrate deeper into the housing. During the penetration, the two groups of ratchet teeth cooperate with each other. The first V-shaped plate is subjected to the extrusion force of the housing shape, resulting in closure. Thus, the two second V-shaped plates can clamp the cable. Therefore, when installing, the cable can be fixed without clamping again, and the fixing effect is good. When the cable is subjected to forces in different directions, it is also very difficult to come out of the housing.

[0017] 2. For this threadless quick connection terminal, screws are provided. After the first V-shaped plate and the second V-shaped plate are deformed by the resistance of the housing, the cable has been firmly clamped. To ensure the connection strength, the screws at the inclined surface positions can be tightened and advanced into the housing, so that the cable can be fixed more firmly between the two second V-shaped plates.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0025] The embodiments of the present utility model provide a threadless quick connection terminal:

[0026] Such as Figures 1-4As shown in the figure, it includes a housing 1. Inside the housing 1, there are two wire clamping components 2. At the ends of the two wire clamping components 2 that are close to each other, a terminal A 3 and a terminal B 4 are respectively fixed. The terminal A 3 and the terminal B 4 can be inserted and cooperatively fixed. The wire clamping component 2 includes a V-shaped plate one 201, a V-shaped plate two 202, and a clamping plate 203. Both the V-shaped plate one 201 and the V-shaped plate two 202 can elastically deform. The V-shaped plate one 201 is inside the housing 1, and the housing 1 is shaped to match the position of the V-shaped plate one 201. When the V-shaped plate one 201 moves into the housing 1, it can be squeezed and closed by the housing 1. There are two V-shaped plates two 202, which are respectively fixed to the two ends of the V-shaped plate one 201. The ends of the two V-shaped plates two 202 that are far from the V-shaped plate one 201 are close to each other. Grooves 204 are opened at the ends of the two V-shaped plates two 202 that are close to each other. There are two sets of clamping plates 203, which are respectively fixed on the sides of the two V-shaped plates two 202 that are close to each other. The clamping plates 203 are inclined towards the inside of the housing 1, and an arc-shaped groove 205 is opened at the end of the clamping plate 203 that is far from the V-shaped plate two 202.

[0027] Both the V-shaped plate one 201 and the V-shaped plate two 202 are made of alloy materials and are covered with copper sheets on the outside, which can conduct electricity. The terminal A 3 and the terminal B 4 are made of copper alloy and play a major role in conducting electricity. The housing 1 is a plastic shell and can be insulated. The clamping plate 203 is a metal sheet, and its end is thinner, which can increase the connection force with the bare wire.

[0028] The ends of the two V-shaped plates two 202 that are far from each other respectively correspond to the upper and lower inner walls of the housing 1. Ratchet teeth 5 are fixed on both the V-shaped plate two 202 and the inner wall of the housing 1. The ratchet teeth 5 of the two are cooperatively arranged. The V-shaped plate two 202 can move into the housing 1 and is prevented from slipping out by the resistance of the ratchet teeth 5.

[0029] The elastic force of the V-shaped plate one 201 can make the ratchet teeth 5 of the V-shaped plate two 202 contact the ratchet teeth 5 of the housing 1, so that the V-shaped plate two 202 can only move in one direction.

[0030] The terminal A 3 includes a sleeve 301 and a V-shaped cover 302. The sleeve 301 is fixed to any one of the V-shaped plates one 201. The V-shaped cover 302 is inside the sleeve 301, and its open end faces outward.

[0031] The terminal B 4 includes a base 401 and a hollow cone 402. The base 401 is fixed to the other V-shaped plate one 201. The hollow cone 402 is fixed on the base 401, with its tip facing outward. The hollow cone 402 cooperates with the V-shaped cover 302, and they can be fixed after being inserted.

[0032] The diameter of the hollow cone 402 is slightly larger than that of the V-shaped cover 302. The V-shaped cover 302 can be expanded and deformed, so the connection force between the two is strong and they can be fixed.

[0033] The middle positions at the upper and lower ends of the housing 1 are both groove-shaped structures, and the sides of the groove-shaped structures are all inclined surfaces. These inclined surfaces cooperate with the inclined surfaces of the first V-shaped plate 201. Screws 6 are installed at the positions of these inclined surfaces. The screws 6 are threadedly connected to the housing 1, and one end of the screw 6 can pass through the housing 1 and contact the first V-shaped plate 201.

[0034] The screws 6 mainly play an auxiliary fixing effect. When all four screws 6 are tightened, the two cables can be firmly clamped.

[0035] Multiple groups of heat dissipation grooves 7 are provided on the housing 1.

[0036] During use, the exposed cable after wire stripping can be inserted between the two second V-shaped plates 202. When inserting, since one end of the two second V-shaped plates 202 is close to each other, and a clamping plate 203 is provided at the position where they are close to each other, the resistance of the cable during insertion is small. However, as the cable is inserted, it will also be clamped by the two second V-shaped plates 202. At the same time, the clamping plate 203 can prevent the cable from slipping out. When continuous pressure is applied, the first V-shaped plate 201 drives the two second V-shaped plates 202 to penetrate deeper into the housing 1. When penetrating, the two sets of ratchet teeth 5 cooperate with each other. The first V-shaped plate 201 is subjected to the extrusion force of the shape of the housing 1, resulting in closing, so that the two second V-shaped plates 202 can clamp the cable. After the first V-shaped plate 201 and the second V-shaped plates 202 are deformed by the resistance of the housing 1, the cable has been firmly clamped. To ensure the connection strength, the screws 6 at the inclined surface positions can be tightened and advanced into the housing 1, so that the cable can be fixed more firmly between the two second V-shaped plates 202.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
