Abstract
The utility model discloses an electric connector with an interlock mechanism for conduction charging, including an insulating casing and a metal member. The metal member includes a spring, a metal buckle and a current conduction member. The connection interlock mechanism is positioned over the product; the current conduction member is positioned in the product; and the connection interlock mechanism and the current conduction member are not communicated with each other. A mechanical lock control portion employs a trigger structure, and the trigger is not exposed and is positioned in the product. Unlocking and locking functions are realized through a special machinery structure by the metal buckle under the effect of a spring, and an electronic lock realizes locking and unlocking functions through a machinery lock structure. The connector provided in the technology scheme effectively solves the machinery and electronic interlock problem of a connector requiring plugging under a heavy current. Simultaneously, the technology scheme satisfies the related requirements in the national standard (GB/T XXXX-201X submitted) and the international standard (IEC 62196-2).
Description
One. technical field
The present invention relates to a kind of electric connector, relate in particular to a kind of electric connector that the conduction-type charging is pegged graft that can be used for.
Two. background technology
Low-carbon economy is the new engine of economic development.New-energy electric vehicle is the development trend of automobile industry, is the new industry that China vigorously supports.The key technology of electric automobile is except battery, and the charging inlet of AC/DC also is an emphasis.The ac/dc charging requirement of electric automobile is accomplished under big electric current.Charging plug will have high reliability, and is suitable for outdoor environment for use.For guaranteeing End-Customer fail safe in use, require to have mechanical lock buckle and electronics latching device.Latching device must be safe and reliable, easy to use.
The existing mechanical snap close is as shown in Figure 1.Snap close adopts single elastic arm hook structure, realizes the mechanical lock buckle of charging plug.This mechanical lock buckle mode is open type, and is unshielded.That can't satisfy actual use resists the requirement that falls to falling, poor reliability.The latch of electronic lock plays locking action through pushing down mechanical lock buckle, and the realization of electronic lock function depends on the operate as normal of mechanical lock.If lost efficacy when the mechanical lock inefficacy can cause electronic lock.
Three. the utility model content
1. technical problem:
The technical problem that the present invention will solve is to the problem of the high reliability of the outdoor use of product, provides a kind of easy to operate, and locking effect is good, and the novel band of high reliability connects the electric connector of snap close.
2. technical scheme
For addressing the above problem; A kind of electric connector that conducts charging with deduction structure with lock, its latching device comprises working of plastics (1), working of plastics (6), trigger movable part (2), spring (3-1), spring (3-2), metal buckle (4), elastic recoil spare (5), working of plastics (7) and hold-down screw (8).Spring (3-1) and spring (3-2) are arranged between trigger movable part (2) and the working of plastics (7), and trigger movable part (2) passes through hole in the working of plastics (1), is positioned at the below of working of plastics (6).Metal buckle (4) is positioned at the below of trigger movable part (2) front end, and down either side is elastic recoil spare (5).Latching device is positioned at the top of hold-down screw (8).
3. beneficial effect
The present technique scheme has solved the mechanical lock buckle problem of electric automobile and the grafting of car end, can realize effective snap close, and is easy to operate.Its specific structure makes coupling mechanism force axially transfer radially favourable lifting coupling mechanism force to by what plug.The design of trigger-type operating structure takes into full account user's operating habit, different and general push type structure.Consider outdoor environment for use simultaneously, the position of trigger does not have exposed parts in the inside of product.Even product falls, can not injure movable part yet, overcome that snap close exposes in the prior art, the ability that external force resistance impacts.
Axial electronic lock and mechanical lock are separate in the present technique scheme, are independent of each other, and have promoted reliability of products.Solved the interconnect problem of axial electronic lock and mechanical lock, avoided because the inefficacy of mechanical lock causes the inefficacy of axial electronic lock.
The present technique scheme is considered electrical security, and the structure of mechanical lock buckle and the structure of current lead-through do not communicate, and are separate, and by built-in screw.

Five. embodiment
As shown in Figure 2, the electric connector of this instance comprises working of plastics (1), working of plastics (6), trigger movable part (2), spring (3-1), spring (3-2), metal buckle (4), elastic recoil spare (5), working of plastics (7) and hold-down screw (8).Spring (3-1) and spring (3-2) are arranged between trigger movable part (2) and the working of plastics (7), and trigger movable part (2) passes through hole in the working of plastics (1), is positioned at the below of working of plastics (6).Metal buckle (4) is positioned at the below of trigger movable part (2) front end, and down either side is elastic recoil spare (5).Latching device is positioned at the top of hold-down screw (8).Current lead-through part (9) is positioned at hold-down screw (8) below, is isolated fully by working of plastics (1) between current lead-through part (9) and the latching device, and is not connected.
As shown in Figure 2, ensconce in the fixed plastics part (1) in the metal trip (4), guarantee to avoid external force and do usefulness. the operator is easy to use.
As shown in Figure 3, when product inserted, the operator pinned trigger movable part (2) and moves right. and the activity space of metal buckle (4) top is released, and two-side elastic resilience part (5) upwards lifts metal buckle (4), is convenient to product and continues to insert.When the product insertion puts in place, unclamp trigger movable part (2), to make under of in the resilience of spring part (3-1) and spring part (3-2), trigger movable part (2) resets.The activity space of metal buckle (4) top is occupied.Metal buckle (4) moves down the entering groove that puts in place, pins socket.When product was extracted, the operator pinned trigger movable part (2), and drive moves right. and the activity space of metal buckle (4) top is released.Elastic recoil spare (5) upwards lifts metal buckle (4).Socket piece (11) withdraws from left.After product withdrawed from, the operator unclamped trigger movable part (2), made under of in the resilience of spring part (3-1) and spring part (3-2), and trigger movable part (2) is moved to the left.At spacing time of working of plastics (1), trigger movable part (2) resets to initial position.
As shown in Figure 4, when mechanical lock buckle pinned product, axially electronic lock latch (10) stretched out to the right, pushes down trigger movable part (2). and when axial electronic lock latch (10) when putting in place, metal buckle (4) is pushed down by axial electronic lock latch (10), is in locking-in state.The effect of trigger movable part (2) was temporarily lost efficacy.The action of trigger movable part this moment (2) no longer influences moving up and down of metal buckle (4).When axial electronic lock release, axially electronics latch (10) is return left.Metal buckle (4) is pushed down by trigger movable part (2), and the move left and right of trigger movable part (2) influences moving up and down of metal buckle (4) once more, plays sealed and effect release.
