Electrical connector with comb-type terminal lock

A method of assembling an electrical connector, comprising:

• providing a connector housing having terminal cavities extending therethrough which are arranged in an array having at least two rows and at least two columns;
• inserting at least two electrical terminals of a plurality of electrical terminals into at least two of the terminal cavities;
• engaging a flexible primary locking mechanism integrally formed with the connector housing in each of the terminal cavities with an edge of each electrical terminal of the plurality of electrical terminals, thereby inhibiting removal of each electrical terminal of the plurality of electrical terminals from each of the terminal cavities;
• slidably attaching a secondary locking mechanism to the connector housing;
• moving the secondary locking mechanism from a pre-staged position to a staged position such that a plurality of members defined by the secondary locking mechanism extend into the terminal cavities and engage the edge of at least one of the plurality of electrical terminals when each of the plurality of electrical terminals is fully seated in the terminal cavities, thereby further inhibiting removal of the plurality of electrical terminals from the terminal cavities;
• and
• wherein the secondary locking mechanism includes a connector locking mechanism configured to attach the electrical connector to a corresponding mating electrical connector and a terminal position assurance device.
