Abstract
The utility model discloses a disconnection brake handle for an electric vehicle, and solves the problems of the conventional disconnection brake handle that as a waterproof disconnection switch has to be welded with a cable before assembly, the brake handle cannot be semi-finished in advance for storage, and the production pressure on workshops in peak seasons is further intensified. The disconnection brake handle is characterized in that the waterproof disconnection switch comprises a switch seat and a locking nut bolted on the switch seat, the switch seat is in threaded connection with a mounting through hole, the cable is sleeved by the locking nut, and a weld point used for being welded with the cable is positioned in the locking nut. The disconnection brake can be conveniently welded with the cable after assembly, so as to be produced into a semi-finished product in advance for storage, which can effectively balance the production pressures in low seasons and peak seasons.
Description
Technical field
The utility model relates to vehicle brake lever field, specifically a kind of electric vehicles outage brake lever.
Background technology
Existing outage brake lever is formed by support, rack-mount outage handle with the waterproof cut-off switch that the outage handle is used, the waterproof cut-off switch is installed in the interior mounting hole of support, with switch locking, other parts such as the handle that will cut off the power supply again are assemblied in (as shown in Figure 1) on the support by the switch locking nut.Because of the assembling after the waterproof cut-off switch and the weld of cable be positioned at mounting hole, the earlier necessary and cable welding of cut-off switch before the assembling, but because cable length has uncertainty, each producer and all different to the requirement of line length with the order of producer's different batches, so the length of cable all needs to intercept according to order requirements, can't make half-blank in advance and carry out the stock, order is more during the busy season, and is bigger to the production pressure in workshop.In addition, because there is multistage positioning step the outside of waterproof cut-off switch, described multistage positioning step is arranged from inside to outside successively from big to small, so the waterproof cut-off switch can only be packed into from the inboard (this side of outage handle promptly is installed) of support, installs inconvenient.
The utility model content
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and a kind of novel outage brake lever of still convenient and cable welding after assembling is provided, and can make half-blank in advance and carry out the stock, the production pressure when slowing down the busy season.
For this reason, the utility model adopts following technical scheme: novel outage brake lever, comprise support and rack-mount outage handle, have one on the support through hole is installed, be equipped with on the described support one with the waterproof cut-off switch that is used of outage handle, it is characterized in that described waterproof cut-off switch comprises switch seat and the jam nut that is screwed onto on the switch seat, switch seat with through hole is installed by be threaded (the waterproof cut-off switch is positioned), jam nut is enclosed within on the cable, is used for being positioned at described jam nut with the weld nugget of cable welding.Because the weld nugget of waterproof cut-off switch and cable welding is positioned at jam nut (promptly be positioned at and install outside the through hole), only jam nut need be backed out and to carry out the welding of cable, convenient welding, so just can make the utility model when the spare time with handle and the rack-mount making partly completed stock of waterproof cut-off switch, (when hurrying) is according to the requirement of order to cable length during the busy season, the cable of intercepting respective length is welded on it on partly completed stock and gets final product, when active balance is not busy and the production pressure when busy, reduced the delivery cycle of product.
As the further of technique scheme improved and replenish, the utility model is taked following technical measures.
Install in the through hole for switch seat can be packed into from the outside of support, the maximum outside diameter that the waterproof cut-off switch in the through hole is installed is positioned at the place that is spirally connected of switch seat, and is easy for installation, solved the drawback that product in the past must be installed from the support inboard.
Above-mentioned novel outage brake lever, jam nut is hat, its outer face has and is used for the hole that cable passes, the external diameter coupling of hole size and cable, reduce the gap between itself and the cable as far as possible,, form many grooves on its outer wall to play waterproof action preferably, increase friction force, be convenient to the dismounting jam nut.
Above-mentioned novel outage brake lever, the outside at the switch seat place of being spirally connected forms a baffle ring, and baffle ring positions switch seat and the degree of being spirally connected that through hole is installed.
The utlity model has following beneficial effect: after assembling, still can make things convenient for and cable welding, make the utility model can make half-blank in advance and carry out the stock, active balance when not busy and the production pressure when busy, reduced the delivery cycle of product; Switch seat can directly be packed into from the outside of support and be installed in the through hole, and is easy for installation.
Below in conjunction with specification drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of existing outage brake lever.
Fig. 2 is an assembling scheme drawing of the present utility model.
Fig. 3 is a structural representation of the present utility model.
The specific embodiment
Outage brake lever shown in Fig. 2-3, outage handle 2 is connected on the support 1 by brake lever axle and spring shaft, has on the support 1 through hole 3 is installed.The waterproof cut-off switch by switch seat 4, be installed in other switch blocks (as contact, conductive pole, sliding bar, tarpaulin etc.) on the switch seat and the jam nut 5 that is screwed onto on the switch seat is formed, switch seat 4 pack into from the outside of support install in the through hole 3 and with through hole is installed by being threaded, jam nut 5 is enclosed within on the cable 6, and the weld nugget on the contact that is used for welding with cable 6 is positioned at jam nut 5.Described jam nut 5 is hat, and its outer face has and is used for the hole that cable passes, the external diameter coupling of hole size and cable; Form many grooves on the outer wall of jam nut.The outside at the switch seat place of being spirally connected forms a baffle ring 7.
The waterproof cut-off switch is used with the outage handle.Under the state of nature, the end face of handle inwardly is pressed into the bulb of switch end, the inner disconnection of switch this moment; Outside pull handle when brake, the bulb of cut-off switch rely on the effect of contained spring to reset naturally, the inner conducting of switch this moment, outage.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all falls in the protection domain of the present utility model any simple modification, equivalent variations and modification that above embodiment did.
