Abstract

An electric connecting apparatus provides electrical connection of two electric components by fitting a plurality of male terminals into mating female terminals. If the male terminals have different lengths, for example, the male terminals are fitted into the female terminals in an order of a longer one to a shorter one. In this case, the inserting force that is needed for the entire array of male terminals at the time the two electric components are connected together does not reach a peak at one time, but the inserting forces for the individual male terminals reach peaks one after another. This can permit the two electric components to be connected together with a less labor.

Claims

1. An electric connecting apparatus for electrically connecting two electric components together, comprising:

an array of male terminals provided on one of said electric components, wherein the array comprises at least four terminals arranged in a row and at least two terminals having a first height are arranged alternatively to the other two terminals having a second height, the second height being different than the firs height;

an array of female terminals provided on the other electric component, each of said female terminals having a pair of holding springs that are pushed apart by a corresponding one of said male terminals inserted therebetweem when said two electric components are connected together, said each pair of holding springs holding the corresponding male terminal therebetween with an elastic force, thereby providing electric contact with the corresponding male terminal; and

time-lag application means for producing a time lag such that inserting forces with which said male terminals are fitted into said female terminals to push apart the respective pairs of holding springs reach peaks at different times when said two electric components are connected together, said time-lag application means including said male terminals having distal ends located at different positions as viewed in a fitting direction in which said male terminals are fitted into said female terminals.

2. The electric connecting apparatus according to claim 1, wherein said time-lag application means further includes a plurality of female terminals having contacts to said male terminals at same positions as seen in said fitting direction of said male terminals.

3. The electric connecting apparatus according to claim 1, wherein said plurality of male terminals are classified into a type having relatively long lengths and a type having relatively short lengths.

4. The electric connecting apparatus according to claim 3, wherein said time-lag application means further includes a plurality of female terminals having contacts to said male terminals at same positions as seen in said fitting direction of said male terminals.

5. The electric connecting apparatus according to claim 1, wherein said time-lag application means further includes a plurality of female terminals having contacts to said male terminals at same positions as seen in said fitting direction of said male terminals.

6. A method of reducing the insertion force required to insert a plurality of male terminals into a plurality of female terminals comprising:

positioning a contact portion of a first subset of said plurality of female terminals at a first location relative to said male terminals, wherein said male terminals have distal ends located at different positions as viewed in a fitting direction in which said male terminals are fitted into said female terminals, an array of male terminals provided on one of said electric components, wherein the array comprises at least four terminals arranged in a row and at least two terminals having a first height are arranged alternatively to the other two terminals having a second height, the second height being different than the first height; and

positioning a contact portion of a second subset of said plurality of female terminals at a second location relative to said male terminals;

whereby different ones of said male terminals make frictional contact with their corresponding female terminals at different moments during the insertion process.

7. The method of claim 6, wherein positioning of some of said female terminals comprises placing said some of said female terminals on spacers.

8. An electric connecting apparatus for electrically connecting two electric components together, comprising:

an array of male terminals provided on one of said electric components;

an array of female terminals provided on the other electric component, each of said female terminals having a pair of holding springs that are pushed apart by a corresponding one of said male terminals inserted therebetween when said two electric components are connected together, said each pair of holding springs holding the corresponding male terminal therebetween with an elastic force, thereby providing electric contact with the corresponding male terminal; and

time-lag application means for producing a time lag such that inserting forces with which said male terminals are fitted into said female terminals to push apart the respective pairs of holding springs reach peaks at different times when said two electric components are connected together, said time-lag application means including a spacer arranged between a board and at least one female terminal included in said array of female terminals, for giving an offset, with respect to another female terminal, to a proximal end of said at least one female terminal in a fitting direction in which said male terminals are fitted into said female terminals.

9. The electric connecting apparatus according to claim 8, wherein said space gives an offset in a manner such that the proximal end of said at least one female terminal is located more remotely from a distal end of the corresponding male terminal than those of other female terminals.

10. The electric connecting apparatus according to claim 9, wherein said-time lag application means includes said male terminals having distal ends located at an identical position as viewed in the fitting direction.

11. The electric connecting apparatus according to claim 10, where said male terminals have an identical length.

12. The electric connecting apparatus of claim 8, wherein the spacer is a separate component from the board, and wherein the spacer is in direct physical contact with one of the female terminals and the board, and wherein a least a portion of the female connector is in physical contact with the board.

13. The electric connecting apparatus according to claim 8, wherein said time-lag application means further includes a plurality of male terminals whose distal ends are all at a same position as seen in said fitting direction of said male terminals to said female terminals.

14. The electric connecting apparatus according to claim 13, wherein said plurality of male terminals all have a same length.
