Abstract

PROBLEM TO BE SOLVED: To provide a connector preventing a terminal bracket from being deformed by a molding pressure when integrally molding it. SOLUTION: The center part of a terminal bracket 10 is formed into a molded part 12 embedded in a connector housing 20 when molding. A reinforced part 13 is formed in the molded part 12 by cutting two slits on its end rim part from the orthogonal direction and raising the space between them. When the connector housing 20 is molded, fused synthetic resin is injected in a cavity, however at this time, since the rising direction of the reinforced part 13 of the terminal bracket 10 coincides with the flow direction of the resin (indicated by an arrow B) as shown in the figure, the injected resin flows into the cavity without receiving any resistance, and the molded part 12 is prevented from being warped and deformed by a pressure from the resin.

FIG. 5 shows a problem in molding the above-mentioned connector. When resin is poured into a molding die, considerable pressure is applied inside the die. For this reason, the central portion of the terminal fitting 101 may be pressed by the molding resin, and the connector 100 may be formed in a state of being bent and deformed. In such a connector 100, since the direction of the terminal fitting 101 is displaced, it hinders connection with another connector. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a connector which prevents deformation of a terminal fitting due to molding pressure during integral molding.

First, both molds 40 and 41 are closed with both tab portions 11 of terminal fitting 10 inserted into mounting grooves 42A and 43A, respectively. Subsequently, as shown by an arrow C in FIG. 3, the molten synthetic resin is injected into the cavity through the injection port 44. FIG. 4 shows a molded state of the connector housing 20 at this time. As shown in the figure, in the present embodiment, a resin injection direction (indicated by an arrow B) is provided in a direction parallel to the rising direction of the reinforcing portion 13 of the terminal fitting 10. At this time, since the reinforcing portion 13 is provided in the mold portion 12 of the terminal fitting 10, the molding portion 12 is prevented from being deformed by receiving the resin pressure when the connector housing 20 is formed. Furthermore, since the resin is poured from a direction parallel to the rising direction of the reinforcing portion 13, the pressure-receiving area of the injected resin is reduced as compared with the conventional case where resistance is received from the entire flat cross section of the terminal fitting. Minutes
Since the cavity is filled while receiving less resistance, the mold portion 12 is more easily prevented from being deformed by bending.

As described above, according to the present embodiment, since the deformation of the terminal fitting 10 is prevented, the alignment of the terminal fitting 10 is stabilized. Also, the reinforcing portion 13
Is a structure in which two cuts are made in the mold portion 12 and only the raised portion is erected therebetween, so that manufacture is extremely simple. Further, since the entire reinforcing portion 13 is surrounded by the connector housing 20, the terminal fitting 10 is connected to the reinforcing portion 1.
3, the retaining force is enhanced. In addition, since the rising direction of the reinforcing portion 13 is set in the direction along the flow direction of the resin, the resistance at the time of pouring the resin can be reduced, and the terminal fitting 10 is hardly bent at the time of molding.

The present invention is not limited to the above-described embodiment. For example, the following ones are also included in the technical scope of the present invention. (1) The present invention is not limited to the relay connector of the above-described embodiment, but can be applied to a connector used for another purpose in which a set of terminal fittings is disposed and incorporated in a housing. (2) The number of terminal fittings incorporated in the connector housing is not limited to two, and may be one or three or more. (3) The reinforcing portion only needs to improve the strength of the mold portion, and may be a member in which a reinforcing member is assembled to the terminal fitting. However, if the reinforcing portion is formed by deforming the material forming the terminal fitting itself, it is not necessary to use a separate member. The reinforcing portion preferably adds a component to the thickness direction of the terminal fitting. For example, the center of the mold portion may be knocked out along the length direction of the terminal fitting and protruded in a ridge shape.
