Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the temperature of the square box-type socket in the prior art rises higher when used, which easily causes the electrical box to melt, and there is a great potential safety hazard, and the insertion force and the pull-out force of the square box-type socket are very high. Large, seriously exceeding the standard requirements, poor comfort, and the loop current through the insurance, the relay can not directly enter the harness end connector

Embodiment 1

[0023] Such as Figure 2 to 5 As shown, the high-elastic tuning fork terminal for the automobile electrical box of this embodiment includes a tuning fork terminal body 1. The tuning fork terminal body 1 is a sheet-shaped structure with a thickness of 0.8 mm, made of copper alloy material, and is engaged on the upper part of the tuning fork terminal body 1. There is an elastic steel card 2. The elastic steel card 2 is an integrated sheet-shaped structure formed by stamping and bending a metal plate and is made of stainless steel. The shape of the elastic steel card 2 is similar to a U shape. The electrical conductivity of the copper alloy material should satisfy the conductivity ≥80% IACS at a temperature of 20°C, and the tensile strength should satisfy the requirement of ≥350MPa at a temperature of 20°C. The U-shaped elastic steel card 2 fits with the fork shape of the upper part of the tuning fork terminal body 1, so as not to affect the insertion of the tuning fork terminal. ...

Embodiment 2

[0034] The high elastic tuning fork terminal for automobile electrical box of this embodiment includes a tuning fork terminal body. The tuning fork terminal body has a sheet-shaped structure with a thickness of 0.8mm. It is made of copper alloy material. The upper part of the tuning fork terminal body is engaged with an elastic steel clip. The elastic steel clip is also a sheet-shaped structure and is made of stainless steel. The shape of the elastic steel clip is similar to the U shape, and the U-shaped elastic steel clip fits the fork shape of the upper part of the tuning fork terminal body.

[0035] The upper part of the main body of the tuning fork terminal is provided with a slot, the top of the slot is provided with an upwardly extending guide structure, and the inner upper part of the slot is wave-shaped. The slot is used for the insertion of a relay or a fuse. When inserting the relay and the fuse, the insertion direction can be guided by the guide structure at the top of ...

Abstract

The invention discloses a high-elasticity tuning fork terminal for an automobile electrical box. The tuning fork terminal comprises a tuning fork terminal body (1), and an elastic steel clamp is arranged on the upper portion of the tuning fork terminal body in a clamping mode. By the arrangement of the elastic steel clamp, the tuning fork terminal can be protected to be used normally in a high temperature environment, and therefore the risk of melting of the electrical box due to temperature rise is avoided. The elastic steel clamp increases the clamping force of the tuning fork terminal on a protector and a relay and improves the current carrying capacity. Compared with a common square-box-type socket, the plugging force is decreased by 50% or so. The tuning fork terminal is simple in structure and light in weight, and will not increase the cost of the automobile electrical box. The tuning fork terminal can be directly plugged into a wiring harness end, so that the path where a loop current flows through is short, the loop voltage drop is small, the temperature is low, the risk of melting of the electrical box due to an over-high temperature is further reduced, and accordingly potential safety hazards are eliminated.

Description

Technical field [0001] The invention relates to a terminal, in particular to a high-elastic tuning fork terminal for automobile electrical box. Background technique [0002] Automotive electrical boxes are mainly composed of plastic shells, metal terminals, circuit boards, insurance, relays and other components, which provide short-circuit or overload protection for automotive electrical appliances and wires to avoid car burning. [0003] At present, sockets equipped with fuse and relay are generally square box type. Such as figure 1 As shown, the relay 14 and the insurance 15 are respectively connected to the upper circuit board 16 through the square box socket 20, and the upper circuit board 16 is connected to the lower circuit board 18 through the conductive posts 21. The lower circuit board 18 is provided with a plug 19, which is connected to the wiring harness. The connector 17 is connected. At this time, the loop current flows through the fuse 15, the relay 14 and the squar...
