Definitions
- the present invention relates to a connector for connecting to a gas filling device for an air bag called a squib, and more particularly to an electrical connector having a lock member for fixing the connector connection.
- a locking member is inserted into a connector housing to reinforce the fitting of a connector in order to more securely fix the fitting to a squib.
- This type of connector is often used, in particular, in a connector that guarantees electrical connection to the ignition device that operates the air filling device of the vehicle airbag.
- the connector on the receiving side has a fixed shape, and a typical connector on the insertion side is a connector housing as described in Patent Document 1.
- the electric wire of the connector is accommodated in the connector housing with an electric wire extending in a fitting direction at the time of electric connection, that is, in a direction orthogonal to a direction of making an electric connection with the electric contact.
- the fitting portion of the connector connection is accommodated in such a manner that the connector housing is locked by a locking portion in the cavity of the squib.
- the fitting portion with the squib includes a connector housing and a lock member mounted on the connector housing, and the lock member is free to face the connector fitting surface.
- the arm has a cantilevered arm extending to the end, and the free end of the arm extends along a tapered surface protruding near the mating surface defined in the connector housing at the time of mating. While sliding, it is deflected outward and latches with the latch portion of the squib at the connector fitting surface. Therefore, the arm is eccentrically biased outward and the free end is accommodated in the accommodating portion of the squib to form a lock portion in the inserting and extracting directions.
- Patent Document 1 Japanese Patent Application Laid-Open No. 2000-164297
- Patent Document 2 Japanese Translation of International Publication No. 2001-512225
- Patent Document 2 requires a high insertion force in order to resist the force of pressing the lock member to slide the free end on the tapered surface. Further, when the electric wire is pulled in various directions, particularly in a direction perpendicular to the extending direction, the locking portion receives an external force, and the locking portion may be deformed or damaged.
- a connector structure using a lock member of another form is required on an industrial scale.
- the present invention has a structure other than the above structure, in which the fitting to the squib is fixed or locked with a low insertion force by using a locking member, and the deformation or breakage of the fitting portion due to an external force is prevented.
- the connector of the present invention is an electrical connector that is fitted to a squib to achieve electrical connection, and includes a lock member and a connector housing,
- the lock member has a pair of parallel extending first arms having a latch surface engageable with the squib, and a pair of second arms parallel to the first arm.
- the connector housing has a pair of third latch arms extending in parallel with the first arm and having a latch surface engageable with the squib; a sliding surface on which the lock member is slidable; A projection on which the free end of the latch arm can be placed,
- the first latch arms elastically deform in opposite directions to enable engagement with the squib.
- the free end of the first latch arm is placed on the protrusion of the connector housing, and at the same time, the second arm is inserted between the slidable surface and the third arm.
- the connector housing has a third elastically deformable arm that fits with the squib, and the lock member fits the first elastically deformable arm with the squib and the elastic deformation of the third arm.
- the first arm moves in the connector insertion direction, and at the same time, the third arm is interposed between the third arm and the elastically displaceable connector housing.
- the third arm can be fixed or locked in a state of being fitted to the squib.
- the insertion operation of the first arm in the structure will be described.
- the first arm force is elastically deformed in cooperation with the S squib.
- the first arm is fixed, and the second arm is also fixed.
- the elastic deformation of the third arm is prevented, and the fitting of the connector is fixed or locked.
- the advantage of this structure is that the connector fitting can be locked with a lower insertion force than the structure in which the first arm locks with the first arm biased as in Patent Document 2, and a strong connector connection is achieved. Can be realized.
- the angle between the latch surface of the first latch arm and the insertion direction of each latch arm is equal to the angle of the third latch arm.
- the angle is smaller than the angle between the latch surface and the insertion direction of each latch arm.
- the connector insertion is made different by making each of the inclination angles of the engagement surface of the third arm of the connector housing and the engagement surface of the first arm of the hook member different.
- the generation time of the elastic restoring action of each arm can be shifted as the distance difference in the entering direction.
- the arm is further pressed in the connector insertion direction so that the defining portion is placed at a predetermined position and abuts a part of the connector housing in the elastic deformation direction, the elasticity of the first arm can be improved. Deformation is restricted, and the first arm can be fixed or locked.
- the electric connector according to the present invention is characterized in that the terminal position force of the surface of the first arm extending in the connector insertion direction is the terminal end of the surface of the third arm extending in the connector insertion direction. It is located rearward in the connector insertion direction with respect to the position.
- At least one of the arms has a material strength including glass fiber.
- the electric connector of the present invention used for the ignition device of the airbag system often has electric wires arranged in a direction orthogonal to the connector connection direction, and when the electric wires are pulled in various directions.
- the engagement surface of the third arm provided on the connector housing and the engagement surface of the first arm provided on the lock member may be deformed by an external force such as pulling.
- both the connector housing and the lock member are formed of a material containing glass fiber having high durability and strength.
- the entire connector is formed from the material, it is very expensive. Therefore, it is economical and practical if at least one of the arms having an engagement surface with the squib is formed of the material.
- the electrical connector of the present invention can be fitted with a structure different from the conventional one and with a low insertion force. Further, the durability of the connector engagement portion is improved.
