Abstract
The utility model relates to an electric car power-off brake handle switch, which comprises a button, an upper casing, a middle casing and a lower casing. The top of the upper casing is provided with an opening. The button is provided with an extension end extending from the opening to the inner side of the upper casing. The button is arranged in a way to be axially movable along the upper casing. A contact mechanism and a resetting member are arranged between the extension end and the upper casing. The upper casing and the middle casing are connected in a sleeving way. A buckle mechanism is arranged between the upper casing and the middle casing. By adopting the above-mentioned technical scheme, the electric car power-off brake handle switch has the advantages of convenient assembly and greater waterproof effects.
Description
Technical field
The utility model relates to a kind of electric motor car outage brake lever switch.
Background technology
Electric motor car outage brake lever switch, generally include button, upper shell, middle shell and lower house, described upper shell top is provided with opening, described button is provided with by described opening and extends to elongated end in the upper shell, described button is provided with contact mechanism and return unit along the axially movable setting of upper shell between described elongated end and the upper shell.Traditional electric motor car outage brake lever switch, earlier by surrounding layer and then paste and fix, it exists, and assembling is loaded down with trivial details, the shortcoming of water proofing property difference between its upper shell and the middle shell.And the wire bonds place that it passes in middle shell is loosening fracture easily, again and, its contact mechanism is the top and bottom contacts, and dust stratification carbon distribution and influence normal contact easily.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of convenient for assembly, the better electric motor car outage of waterproof effect brake lever switch.
For achieving the above object, the utility model provides following technical scheme: a kind of electric motor car outage brake lever switch, comprise button, upper shell, middle shell and lower house, described upper shell top is provided with opening, described button is provided with by described opening and extends to elongated end in the upper shell, described button is along the axially movable setting of upper shell, be provided with contact mechanism and return unit between described elongated end and the upper shell, described upper shell is socket with middle shell and is connected, and is provided with snap device between described upper shell and the middle shell.
By adopting technique scheme, make that the assembling of electric motor car outage brake lever switch is simpler, and have better waterproof effect.
The utility model further arranges: an end of described middle shell is set in the end outside of upper shell, described snap device comprise the boss that is arranged on the upper shell sidewall and be arranged on the middle shell sidewall with the suitable bayonet socket of boss.
The utility model further arranges: the relative upper shell other end of described middle shell is provided with two resilient clamp sheets at least, be provided with the space of passing for lead between the resilient clamp sheet, described lower house is set in the outside of middle shell, and the inwall of described lower house is conical surface shape setting wide at the top and narrow at the bottom.
By adopting technique scheme, the resilient clamp sheet has avoided lead to rupture because of loosening stationary contact spare and the wire bonds place of causing by cooperating with clamping wire of being with the inwall of lower house.
The utility model further arranges: described contact mechanism comprises movable contact piece and stationary contact spare, and described movable contact piece is arranged on the sidewall of described elongated end, and described stationary contact spare and movable contact piece are slidingtype and match and be arranged on the madial wall of upper shell.
By adopting technique scheme, reduced the dust stratification carbon distribution of contact mechanism, and prolonged useful life.
The utility model further arranges: described button is provided with bucker, and described bucker is provided with gland, and described bucker is provided with the shirt rim, described gland and the clamping of upper shell phase, and described shirt rim is folded between gland and the upper shell.
By adopting technique scheme, further improved waterproof effect.
Below in conjunction with accompanying drawing the utility model is further described.
