In other words, such a connector requires a larger number of terminals to be mounted in a smaller space (base). The base of the connector has a hole corresponding to the position of the terminal. If the number of terminals is increased, the structural strength of the base is lowered. In addition, since the width of the terminal is reduced, the structural strength of the terminal itself is also weak. For such connectors, the difference in force applied to the terminals by different operators during assembly may cause the terminals to be bent and bent and not properly mounted on the base. Moreover, since the width of the terminal is too small and the number is considerably large, it is difficult for the operator to directly judge with the naked eye whether the terminal is correctly assembled. Therefore, such connectors tend to have a high defect rate.
