Board-mounted connector

摘要

An object is to provide a board-mounted connector which has an assembly fitting opening provided on the attachment surface side of an external shield shell onto a circuit board such that a housing assembly can be fit from the assembly fitting opening into the external shield shell, and is capable of improving the ease of assembling the housing assembly. In a board-mounted connector 1A, a housing assembly 21A to be fit from an assembly fitting opening 34 provided at an external shield shell 11A into the external shield shell 11A is made by integrally forming an internal housing 23 that accommodates a plurality of connection terminal members 22 and an external housing 26 that covers the outer circumference of the internal housing 23 and accommodates and holds the internal shield shell 25.

主权项

1. A board-mounted connector comprising an external shield shell having one surface that is attached onto a circuit board so as to form an electromagnetic shielding space between the external shield shell and the circuit board and one side that is perpendicular to a surface of the circuit board and is open for fitting a counterpart connector, and a housing assembly that is fit into the external shield shell and into and to which the counterpart connector is fit and connected from the one side of the external shield shell, wherein
the housing assembly includes connection terminal members each of which has one end that is a lead terminal which is connected to a contact node on the circuit board, and the other end that is a connector terminal which is fit into and connected to a connection terminal of the counterpart connector, an internal housing that is made of an insulating resin and accommodates the connection terminal members, an internal shield shell that covers an outer circumference of the internal housing and is conductively connected to a corresponding shield member of the counterpart connector, and an external housing that is made of an insulating resin and accommodates and holds the internal shield shell; the external shield shell is provided with an assembly fitting opening which is formed on an attachment surface side with respect to the circuit board such that the housing assembly can be fit thereinto; the internal housing and the external housing which constitute the housing assembly are integrally formed; on inner surfaces of both side walls of the external shield shell, positioning spring members are provided to extend along a fitting direction of the housing assembly; at both side surfaces of the external housing, guide grooves are provided to be engaged with the positioning spring members during fitting into the external shield shell, thereby performing positioning; and the guide grooves extend in a direction perpendicular to a face of the circuit board on which the external shield shell is attached.
