Claims (5)

  1. 1. A low-fitting-force connector includes a1 st housing having a cover portion, a2 nd housing fitted into the cover portion, and a slide lever slidably and rotatably assembled to the 2 nd housing, The slide bar has: a cam groove engageable with a1 st cam pin provided in the cover portion, and A sliding guide portion for receiving and enabling sliding of a2 nd cam pin provided to the 2 nd housing, The slide lever is displaceable relative to the 2 nd housing between an initial position at which the two housings are initially engaged, an engagement completion position at which the two housings are engaged, and a slide position at which the two housings are engaged while being moved from the initial position to the engagement completion position, The slide guide portion extends in a crossing direction crossing the fitting direction of the two housings in a state where the slide lever is at the initial position, In an initial stage of fitting of the housings, in a state in which the 1 st cam pin is introduced into the cam groove of the slide lever at the initial position, the housings are fitted by a cam action between the cam groove and the 1 st cam pin in accordance with a slide operation of sliding the slide lever with respect to the 2 nd housing to move the 2 nd cam pin in the intersecting direction by the slide guide portion, The 2 nd cam pin is pushed in the fitting direction by the slide guide portion and the two housings are fitted together with a rotation operation of rotating the slide lever in the slide position by the slide operation to the fitting completion position about the 1 st cam pin disposed in the cam groove.
  2. 2. The low-k fitting force connector of claim 1, wherein, The slide bar is set so as not to protrude from the 1 st housing in the crossing direction in a state of being arranged at the fitting completion position.
  3. 3. The low-mating force connector according to claim 1 or claim 2, wherein, The slide guide portion has a long hole shape extending in the intersecting direction.
  4. 4. The low-mating force connector according to claim 1 or claim 2, wherein, The slide guide portion extends in an orthogonal direction orthogonal to the fitting direction of the housings in a state in which the slide lever is in the initial position, and extends in a direction inclined from the orthogonal direction along the 1 st cam pin side and arranged on the opposite side of the fitting direction in a state in which the slide lever is in the fitting completion position.
  5. 5. The low-mating force connector according to claim 1 or claim 2, wherein, The slide lever includes a plate-like arm portion having the cam groove and the slide guide portion, and an engagement portion protruding in an extending direction of the slide guide portion is provided on an outer periphery of the arm portion, The cover portion is provided with a portion to be locked, the portion to be locked being capable of being locked to the locking portion in response to the sliding operation of the slide lever from the initial position to the sliding position, and the locking portion being configured to press the portion to be locked in response to the rotating operation of the slide lever, thereby fitting the two housings.

Description

Low fitting force connector Technical Field The invention relates to a low-chimeric-force connector. Background Conventionally, various connectors have been proposed which can reduce the load (fitting force) required for fitting the connectors. For example, patent document 1 discloses a lever type connector in which a lever having a cam groove is attached to one housing, a cam shaft is provided to the other housing, and the two housings are fitted by cam action by rotating the lever after bringing the two housings close to each other and bringing the cam shaft into the cam groove. Patent document 2 discloses a sliding connector in which a slider having a cam groove is attached to one housing, and an engagement pin is provided to the other housing, and the two housings are engaged by a cam action of pulling the engagement pin into the cam groove by pushing the slider in a sliding direction in a state in which the connector housings are abutted against each other. Further, patent document 3 describes a connector having a structure in which both a lever and a slider which are independently configured are assembled to one connector housing. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2009-87852 Patent document 2 Japanese patent application laid-open No. 2015-90797 Patent document 3 Japanese patent laid-open No. 11-329583 Disclosure of Invention Problems to be solved by the invention However, the lever-type connector described above has a relatively large effect of reducing the load (fitting force) required for the fitting operation, but a wide space for rotating the lever is required on the rear surface side of the connector, and may not be applicable to a wire harness or ECU provided in a narrow portion. On the other hand, although the sliding connector does not require a space for operation on the rear surface side of the connector, the effect of reducing the load required for the fitting operation is relatively small, and in the case where the number of poles of the connector is large, the load may not be reduced to a required standard value. Further, the connector in which the rod and the slider are assembled is problematic in that the number of components is large, and the structure and the assembling work are complicated. Means for solving the problems The low fitting force connector of the present invention includes a 1 st housing having a cover portion, a2 nd housing fitted into the cover portion, and a slide lever slidably and rotatably assembled to the 2 nd housing, the slide lever having a cam groove engageable with a 1 st cam pin provided to the cover portion, and a slide guide portion receiving and slidably receiving a2 nd cam pin provided to the 2 nd housing, the slide lever being positioned at the initial position when the two housings are started to be fitted, being positioned at the slide position when the two housings are completed to be fitted, being positioned at the slide position in a period from the initial position to the fitting completion position, being extended in a crossing direction crossing a fitting direction of the two housings in a state where the slide lever is positioned at the initial position, being positioned at the first position in the cam groove, being brought into contact with the slide pin by the slide lever in the crossing direction of the two housings in the first position, being pressed against the slide pin by the slide lever in the sliding direction by the slide lever, and being brought into contact with the slide pin in the sliding direction 2 by the slide lever in the second position when the two housings are brought into contact with the slide pin by the slide lever in the sliding direction 2. Effects of the invention According to the low fitting force connector of the present invention, the space for the fitting operation can be reduced with a simple structure than before, and the load (fitting force) required for the fitting operation can be sufficiently reduced.
