Description of Embodiments
A preferred embodiment of an insert molding method for a connector according to the present invention will be explained in detail with reference to the drawings hereinafter. Here, it should be noted that the present invention is not limited by this embodiment. Fig.1 is a perspective view showing a connector 1 that is manufactured by an insert molding method for a connector according to an embodiment of the present invention. Fig.2 is a view explaining such a situation that the connector 1 shown in Fig.1 is about to be inserted into a circuit substrate 50. The connector 1 is equipped with signal system terminals 10, power system terminals 20, bushes 30, and a housing 40.
The signal system terminals 10 are connected to the circuit substrate 50, and correspond to the terminals that transmit a control signal of a small electric current respectively. As shown in Fig.3, a dimension S of the signal system terminal 10 in the longitudinal direction is long, e.g., is about 76 mm. Therefore, as shown in Fig.4, a warp in the longitudinal direction is caused after the press molding is applied.
The power system terminals 20 are welded to a power supply substrate (not shown), and correspond to the terminals that transmit a power supply current of a large electric current respectively. The bushes 30 constitute the fitting holes that are used to fit the housing 40 to a unit 60 described later.
As shown in Fig. 1 , the connector 1 is constructed such that the signal system terminals 10, the power system terminals 20, and the bushes 30, all being the insert components, are integrated with the housing 40 by the insert molding. As shown in Fig.2, the connector 1 is attached to the unit 60 by bolts 60a, then the signal system terminals 10 are soldered to the circuit substrate 50, and then the power system terminals 20 are welded on to the power supply substrate (not shown). The signal system terminals 10 are aligned in a row when a comb-teeth shaped jig 70 is put on to these terminals 10, i.e. , each signal system terminal 10 gets into grooves 70b between comb teeth 70a respectively. Then, the signal system terminals 10 are inserted correspondingly into connection holes 50a of the circuit substrate 50 in their aligned state. Then, the signal system terminals 10 are soldered on to the circuit substrate 50.
Next, the insert molding method for the connector according to the present embodiment will be explained with reference to Fig.5 hereunder. Figs.5A to D are views explaining the insert molding method for the connector.
First, as shown in Fig. 5A, the signal system terminals 10 are set over a housing mold 80. That is, the signal system terminals 10 in two rows are set over the signal system terminal setting holes 80a while directing their warping directions D outward respectively. More concretely, the signal system terminals 10 in two rows are aligned respectively such that the warping directions D of all signal system terminals 10 in each row are directed outward in the direction, along which paired terminals in two rows out of all signal system terminals 10 are opposed to each other, respectively. Then, as shown in Fig. 5B, a plurality of signal system terminals 10 in two rows are inserted into signal system terminal setting holes 80a as the setting holes in the housing mold 80, as described in detail later.
Then, as shown in Fig.5C, a resin used to form the housing 40, etc. are injected into the housing mold 80, and thus the connector 1 in which the insert components are integrated with the housing 40 is molded. Although not shown in Fig.5C, it is assumed that the setting of the power system terminal 20 and the bush 30, both prepared as the insert component, in the housing mold 80 should also be completed before the resin, etc. are injected into the housing mold 80.
Then, as shown in FIG.5D, the connector 1 is released from the housing mold 80, and thus the insert molding method for the connector according to the embodiment of the present invention is completed. In the connector 1 manufactured by this insert molding method for the connector, as shown in Fig.5D, the warping directions D of respective signal system terminal 10 are still directed to the outer side of the rows of the terminals respectively. The reason for this is that, because the spring characteristics of the metal itself is tough, an amount of warp of the signal system terminals 10 would not be changed just after the signal system terminals 10 are set merely in the signal system terminal setting holes 80a of the housing mold 80.
Next, procedures required until the connector 1 that is manufactured by the insert molding method for the connector according to the embodiment of the present invention is inserted into the circuit substrate 50 will be illustrated hereunder. Figs.6 A to C are views illustrating procedures required until the connector 1 shown in Fig.2 is inserted into the circuit substrate 50. First, as shown in Fig.6A, the connector 1 is arranged in the position where the signal system terminals 10 of the connector 1 substantially oppose to the connection holes 50a in the circuit substrate 50. At this time, the warping directions D of the signal system terminals 10 are directed toward the outer side of two rows of the terminals respectively.
Then, as shown in Fig.6B, the comb-teeth shaped jig 70 is put on to the rows of the signal system terminals 10 from the outer side on both sides respectively. At this time, the warping directions D of the signal system terminals 10 are directed to the outer side of the rows. Therefore, the comb-teeth shaped jig 70 can be put on to the signal system terminals 10 in respective rows from the outer side of the rows of the terminals without fail respectively. That is, the signal system terminals 10 in two rows can be aligned without fail.
Then, as shown in Fig.6C, the signal system terminals 10 are inserted into the connection holes in the circuit substrate 50. At this time, since the signal system terminals 10 are aligned by the comb-teeth shaped jig 70, these signal system terminals 10 can be inserted easily into the connection holes 50a in the circuit substrate 50.
In this embodiment, a plurality of signal system terminals 10 aligned in two rows are integrated with the housing 40 such that their warping directions D are directed to the outer side of the rows of the terminals respectively. Therefore, in the manufactured connector 1 , the comb-teeth shaped jig 70 can be put on to the signal system terminals 10, which are already warped outward from respective rows, from the outer side of a plurality of signal system terminals 10 being aligned in two rows without fail respectively. As a result, the insertion of the signal system terminals 10 into the connection holes 50a in the circuit substrate 50 can be facilitated.
Also, in this embodiment, the signal system terminals 10, in which a warp in the longitudinal direction is easily caused because its dimension in the longitudinal direction is long, are integrated with the housing 40 such that the warping directions D are directed toward the outer side of the rows of the terminals respectively. Therefore, in the manufactured connector 1 , the comb-teeth shaped jig 70 can be put on to the signal system terminals 10, which are already warped outward from the rows, from the outer side of a plurality of signal system terminals 10 aligned in two rows without fail respectively. As a result, the insertion of the easily warped signal system terminals 10 into the connection holes 50a in the circuit substrate 50 can be facilitated.
Also, in this embodiment, a warp correction or a warp suppression of respective signal system terminals 10, which is needed to correctly position the signal system terminals 10, can be omitted . Consequently, a cost reducing effect achieved by the omission of steps can be obtained. Here, in this embodiment, the connector 1 having the signal system terminal 10 and the power system terminal 20 is illustrated, but the present invention is not limited this connector. The present invention may be applied to any connector if such connector has a plurality of terminals. In other words, the terminals whose warping directions D are put in predetermined directions are not limited to the signal system terminal 10, and other terminals may also be employed.
This application is based upon and claims the benefit of priority of Japanese Patent Application No. 2010-155500 filed on July 8, 2010, the contents of which are incorporated herein by reference.
Industrial Applicability
According to the insert molding method of the present invention, a plurality of signal system terminals that are aligned in two rows are set in the housing mold such that the warping direction are respectively directed to outer sides of the rows of the terminals.

Consequently, the insertion of the terminals into insertion destination places for the terminals can be facilitated .
