This application is based on and claims priority under 35 U.S.C. ยง 119 to Japanese Patent Application No. JP2020-144688 filed Aug. 28, 2020, the contents of which are incorporated herein in their entirety by reference.
BACKGROUND OF THE INVENTION
This invention relates to a locator for aligning cables which are configured to be connected with a circuit board.
Referring to FIGS. 15 and 16, JPA2018-152244 (Patent Document 1) discloses a connector 900 which is configured to be connected with a composite cable 950 including a plurality of cables 960. Specifically, the connector 900 comprises a mating portion 910, a circuit board 920, a locator 930 and a back shell 940. The mating portion 910 is configured to be mated with a mating connector, which is not shown in the figure, along a front-rear direction. In the figure, the front-rear direction is a Y-direction. The circuit board 920 is connected with the mating portion 910. The circuit board 920 is formed with a plurality of pads 922. The circuit board 920 is provided with an accommodated portion 924. The locator 930 has a circuit board accommodating portion 932 and a plurality of through holes 934. Specifically, the circuit board accommodating portion 932 opens forward. In the figure, forward is a negative Y-direction. The accommodated portion 924 of the circuit board 920 is accommodated in the circuit board accommodating portion 932 of the locator 930. The cables 960 included in the composite cable 950 are held by the through holes 932, respectively, of the locator 930 and are thereby positioned both in a pitch direction and in an up-down direction. In the figure, the pitch direction is an X-direction while the up-down direction is a Z-direction. A core wire 962 of the cable 960 is connected with the pad 922 of the circuit board 920. The back shell 940 is attached to a rear end part of the mating portion 910 so as to cover the pads 922 of the circuit board 920.
According to Patent Document 1, the cable 960 and the circuit board accommodating portion 932 overlap with each other in the up-down direction at an area rearward of the through hole 934 of the locator 930. Thus, as an outer diameter of the cable 960 becomes larger, the through hole 934 must be positioned away from the circuit board accommodating portion 932 in the up-down direction in consideration with a positional relationship between an outer periphery of the cable 960 and the circuit board accommodating portion 932. Consequently, according to Patent Document 1, as the outer diameter of the cable 960 becomes larger, the locator 930 has an increased size in the up-down direction and thereby the connector 900 has an increased size in the up-down direction.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a locator which is provided in a connector and can prevent the connector from having an increased size even if a cable connected with the connector has an increased outer diameter.
One aspect (first aspect) of the present invention provides a locator for aligning cables which are configured to be connected with a circuit board having an accommodated portion. The locator comprises at least a main portion which extends in a pitch direction. The main portion is, at least in part, formed with at least one circuit board accommodating portion. The main portion is formed with at least one first through hole and at least one second through hole which is different from the first through hole. The at least one circuit board accommodating portion is configured to accommodate the accommodated portion of the circuit board. The at least one circuit board accommodating portion opens at least forward in a front-rear direction perpendicular to the pitch direction. Each of the at least one first through hole and the at least one second through hole pierces the main portion in the front-rear direction. Each of the at least one first through hole and the at least one second through hole holds one of the cables to position the one of the cables both in the pitch direction and in an up-down direction which is perpendicular to both the pitch direction and the front-rear direction. In the pitch direction, the at least one first through hole is provided at a location which is different from a location of the circuit board accommodating portion.
Another aspect (second aspect) of the present invention provides a connector comprising a mating portion, the circuit board and the locator of the first aspect. The mating portion is configured to be mated with a mating connector. The circuit board is connected with the mating portion. The circuit board has the accommodated portion. The accommodated portion is accommodated in the circuit board accommodating portion to be positioned both in the pitch direction and in the up-down direction.
Still another aspect (third aspect) of the present invention provides a harness comprising a connector and a composite cable which is connected with the connector. The connector comprises a mating portion, the circuit board and the locator of the first aspect. The mating portion is configured to be mated with a mating connector. The circuit board is connected with the mating portion. The circuit board has the accommodated portion. The accommodated portion is accommodated in the circuit board accommodating portion to be positioned both in the pitch direction and in the up-down direction. The composite cable comprises the cables. The cables are aligned by the locator and are connected with the circuit board.
The locator of the present invention is configured so that, in the pitch direction, the first through hole, which is one of through holes aligning the cables, is provided at the location which is different from the location of the circuit board accommodating portion. Accordingly, the circuit board accommodating portion does not restrict a size of a cable which is held by the first through hole. Thus, without increasing a size of the locator in the up-down direction, the locator of the present invention can align a cable with an increased outer diameter which corresponds to the first through hole. In other words, the locator of the present embodiment prevents a connector from having an increased size even if cables, for example twisted pair lines, which are connected to the connector, have increased outer diameters.
An appreciation of the objectives of the present invention and a more complete understanding of its structure may be had by studying the following description of the preferred embodiment and by referring to the accompanying drawings.

Accordingly, none of the circuit board accommodating portions 210 restrict a size of the first cable 520 which is held by the first through hole 220. Thus, without increasing a size of the locator 100 in the up-down direction, the locator 100 can align the first cable 520 with an increased outer diameter which corresponds to the first through hole 220. In other words, the locator 100 of the present embodiment can prevent the connector 600 from having an increased size even if the twisted pair lines of the first cable 520, which are connected to the connector 600, have increased outer diameters.
As shown in FIG. 9, the second through holes 230 of the present embodiment are arranged in two rows in the up-down direction.
