Connector-equipped Communication Module Height Reduction via Segmented Side Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication module connectors with side terminals interfere with antenna elements, deteriorating antenna characteristics and hindering height reduction in communication devices.
Innovation Solution
A connector-equipped communication module design with side terminals only in the IC-mounted region of the wiring board, where inner wall terminals in the connector contact the side terminals, allowing for reduced height without affecting the antenna element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If side terminals are provided on the communication module for height reduction, then connector thickness is reduced, but antenna characteristics are deteriorated
Solution Approach 1:
The wiring board is divided into two distinct regions: an antenna-mounted region and an IC-mounted region. Side terminals are provided only in the IC-mounted region and peripheral portions, completely avoiding the antenna-mounted region. This spatial segmentation allows the connector thickness to be reduced through side terminal connection while preventing any adverse effect on the antenna element, as the terminals and antenna are separated in different zones of the wiring board.
2Length of stationary object
If terminals are formed on the side surface of the module for height reduction, then overall height is reduced, but antenna element characteristics are adversely affected
Solution Approach 1:
Different regions of the wiring board are assigned different functions and terminal configurations. The antenna-mounted region is designed without side terminals to maintain optimal antenna characteristics, while the IC-mounted region incorporates side terminals to enable height reduction. This local differentiation of quality and structure allows the module to achieve compact height while protecting the antenna element from adverse effects.

AI summary
A connector-equipped communication module includes a communication module and a connector. The communication module includes a wiring board including antenna-mounted and IC-mounted regions at different positions in a planar view, an antenna element mounted in the antenna-mounted region, a wireless IC and a mounted component mounted in the IC-mounted region, and side terminals in the IC-mounted region and peripheral portions near the IC-mounted region. The connector includes a receiving portion including a placement portion configured to mount the communication module and a wall portion extending around the placement portion, inner wall terminals on an inner side of the wall portion at positions facing the side terminals, and external terminals located outward of the receiving portion and electrically connected to the inner wall terminals. In a state where the communication module is received in the receiving portion, the inner wall and side terminals are fitted so as to contact with each other.
