Problems solved by technology

However, it is necessary to mold the locking member 5 into a three-dimensional shape in accordance with the shapes of the cancellation protrusion 2b and the connector lead-out portion 3b of the steering angle sensor 1, so the mold structure for forming the locking member 5 becomes complicated, and the locking member 5 may be distorted. The problem of skyrocketing production costs
Moreover, because the locking member 5 is held on the steering angle sensor 1 only by the fitting force of the engaging protrusion 7a formed on the cover 7, it is easy to use it accidentally during the transportation process after the product leaves the factory. The problem that the locking part 5 falls off

Embodiment Construction

[0036] Specific embodiments of the present invention will be described below with reference to the accompanying drawings. figure 1 It is a top view of the lock member according to the first embodiment of the present invention, figure 2 is a perspective view showing the state before the lock member is mounted on the steering angle sensor, image 3 It is a perspective view showing the state after the lock member is attached to the steering angle sensor.

[0037] The steering angle sensor 1 that adopts the locking member 10 involved in this embodiment is a rotation angle detection device that detects the steering angle of the steering wheel, and its basic structure is the same as that of Figure 8 and Figure 9 The structure shown is the same. That is, if figure 2 and image 3 As shown in FIG. figure 2 , 3 Middle is the upper end) is provided with canceling protrusion 2b. A code plate not shown in the drawing is integrated with the rotor member 2 , and a plurality of d...

Abstract

The present invention provides a cheap lock component that can be simply and reliably assembled and disassembled on a rotation angle detection apparatus. The lock component (10) that assembled and disassembled on a rotation angle sensor (1) is composed by a main face (11) and a sub face (12), wherein the main face is provided with clamping holes (13, 14, 15) from the first to the third, and the sub face stretches out from the main face with its front-end provided with a clamp protrusion (12a), and the main face and the sub face are formed by flexible thin-film machininged by demoulding. Insert a cancel protrusion (2b) and a connector lead division (3b) into and clamp them inside the first and the second clamping holes on the main face, cut in the sub face through a centre hole (2a) on a rotor component (2) and wind it into annular at the same time, clamp the clamp protrusion on the sub face inside the third clamp hole on the main face, so as to make a rotor component stayed in rotate neutral position through a lock component, until the rotation angle sensor is installed onto a automobile rotation angle device.

Description

technical field [0001] The present invention relates to a lock member that can be attached to and detached from a rotation angle detection device such as a steering angle sensor, and is used to hold a rotor member at a rotationally neutral position when it is installed. Background technique [0002] The steering angle sensor is an example of a rotation angle detection device, and is used as a rotation information detection mechanism for detecting the steering angle of the steering wheel. The stator member and a plurality of detection elements arranged inside the stator member are constituted. The steering angle sensor roughly constituted in this way is mounted and used on an automobile steering device in a state where a steering shaft is inserted through a center hole of a rotor member. At this time, it is set so that the steering shaft rotates clockwise and counterclockwise multiple times (for example, twice) from the neutral position of rotation (the position at which the...
