Therefore, the connector 10 protects corresponding portions of the receptacle insulator 30 from two directions, and can prevent damage to the receptacle insulator 30 during fitting.
  • the electronic component for example, CPU, controller, or memory
  • the electronic component for example, high-function module, semiconductor, or large-capacity memory
  • each lock member may be interchanged between the receptacle connector 20 and the plug connector 60.
  • the plug lock member 90a is not limited to a configuration that is held only by one support portion 75 formed on the annular wall 72. Two plug lock members 90 a may be held by two support portions 75 formed on the annular wall 72, respectively.
  • the elastic deformation portion 92a of the plug lock member 90a is not limited to a configuration in which the elastic deformation portion 92a is held at the end of the annular wall 72 in the longitudinal direction of the connector 10, that is, the left-right direction, and elastically deforms in the same direction.
  • the elastic deformation portion 92a may be configured to be held by the end portion of the annular wall 72 in the short direction of the connector 10, that is, the front-rear direction, and to elastically deform in the same direction.
  • the operation unit 93a may be configured to contact a part of the receptacle connector 20 at a predetermined position so that the operation unit 93a of the plug lock member 90a is not excessively displaced and plastically deformed.
  • the operation portion 93a may be configured such that the inner surface thereof contacts the corresponding outer surface of the receptacle lock member 50 when being pushed inward.
  • the front-rear width of the operation unit 93a may be equal to the front-rear width of the plug connector 60. Thereby, in the connector 10, the operativity of the operation part 93a improves.
  • the engaging part 51 may have elasticity. At this time, a predetermined gap may be provided between the engaging portion 51 and the corresponding protrusion 36a. The engagement portion 51 may be elastically deformed outward in the gap when the plug lock member 90a is in contact with the elastic deformation portion 92a.
  • the lock portion 94a is not limited to a configuration that penetrates the central portion of the elastic deformation portion 92a in a substantially rectangular shape.
  • the lock portion 94a may penetrate the central portion of the elastic deformation portion 92a in an arbitrary shape.
  • the lock portion 94a may be recessed in the surface of the elastic deformation portion 92a without penetrating the elastic deformation portion 92a.
  • the lock portion 94a may be configured as a part of the surface of the elastically deformable portion 92a without penetrating and not being recessed.
  • the surface of the elastically deformable portion 92a that is, the surface of the lock portion 94a and the engaging portion 51 may abut.
  • the fitting / holding force between the receptacle connector 20 and the plug connector 60 may be based on the elastic force of the elastic deformation portion 92 a acting on the surface of the engaging portion 51.

Abstract

L'invention concerne un raccord qui permet d'obtenir une force de maintien d'ajustement suffisante même dans un état dans lequel le raccord est réduit en hauteur et en taille et qui qui a une excellente facilité d'insertion et de retrait. Un raccord (10) selon la présente invention comprend : un premier raccord (20) comprenant un premier isolant (30) qui a une section convexe d'ajustement (33) et un premier élément de verrouillage (50) qui est maintenu par le premier isolant (30) ; et un second raccord (60) comprenant un second isolant (70) qui a une section concave d'ajustement (73) destinée à être ajustée à la section convexe d'ajustement (33) et un second élément de verrouillage (90a) qui est maintenu par le second isolant (70). Un élément du premier élément de verrouillage (50) et du second élément de verrouillage (90a) a une section élastiquement déformable (92a) qui a une élasticité et une section d'actionnement (93a) permettant d'actionner la section élastiquement déformable (92a), et l'autre élément a une section de prise (51) qui est en prise avec la section élastiquement déformable (92a) lorsque le premier raccord (20) et le second raccord (60) sont ajustés l'un à l'autre.
