"Connector with Electronic Component and Holder" in Patent Application Approval Process

August 28, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- A patent application by the inventors Ando, Motohiro (Yokkaichi-City, JP); Kondo, Tomoyuki (Yokkaichi-City, JP), filed on February 4, 2014, was made available online on August 14, 2014, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application is assigned to Sumitomo Wiring Systems, Ltd.

The following quote was obtained by the news editors from the background information supplied by the inventors: "The invention relates to a connector with an electronic component and a holder.

"The waterproof connector disclosed in Japanese Unexamined Patent Publication No. 2012-109158 requires the rear holder to hold the holder and the housing. Thus, the number of components increases and the overall structure is complicated.

"The invention was completed in view of the above situation and aims to simplify a structure of a connector with an electronic component."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "The invention relates to a connector with at least one electronic component; a holder for holding the electronic component and a housing with an insertion opening for receiving the holder. The opening opens in only one direction, and is configured to accommodate the holder that holds the electronic component. At least one conductive member conductively connects the electronic component and a mating terminal fitting of a mating connector. The conductive member includes at least one holder press-fit portion to be press-fit into the holder and a housing press-fit portion to be press-fit into the housing. The holder is held in the housing by the conductive member.

"The holder press-fit portion on the conductive member is press-fit into the holder that holds the electronic component. The housing opens in only one direction and the holder into which the conductive member is press-fit is inserted into the housing. The housing press-fit portion of the conductive member is press-fit into the housing when the holder is accommodated at a specified position in the housing. The conductive member holds the holder and the housing by being press-fit. Thus, the holder is held in the housing via the conductive member. Therefore it is not necessary to use another component and the number of components can be reduced. Further, there is no need for a hole or a projection. Hence, there is no need for a structure for sealing the hole or the like in the housing and the interior of the housing is fluid- or waterproofed easily.

"The conductive member may include two of the housing press-fit portions that project laterally from outer side surfaces of the holder. Thus, a holding force can be improved since the conductive member is fixed to the housing at two points. Further, the laterally projecting housing press-fit portions can receive the forces when the holder and the conductive member are inserted into the housing and avoid the need to apply an unnecessary force to the holder. The holder generally is made of resin, and a press-fit force applied to the holder could form cracks at a position where the force is applied. However, the conductive member generally is made of metal and can receive the press-fit force without cracking. Thus, the resin of the holder is not likely to crack.

"The housing may include a thick portion into which the housing press-fit portion is to be press-fitted. A force tends is applied to the position where the housing press-fit portion is press-fit. However, the housing is thickened at the press-fitted position so that breaks, cracks and the like are not likely to form.

"The holder press-fit portion may be a projection projecting substantially from a center of the conductive member. The finished sizes of the conductive member and the holder vary within tolerances. However, the influence of displacements caused by such variation ranges on positioning the housing press-fit portion can be reduced.

"The conductive member may comprise first and second conductive members that are insertable substantially in parallel into the holder in first and second rows. Each of the first and second conductive members may include terminals to be connected to the mating terminal fittings, a coupling that couples the terminals and an electronic component connecting portion to be welded to the electronic component. The electronic component connecting portion of the first conductive member may include a bent portion and a first connection portion projecting from the holder and to be welded electrically to the electronic component. The electronic component connecting portion of the second conductive member may include a second connection portion on substantially the same plane as the coupling and projecting from the holder for electrical connection to the electronic component. The first and second welding portions may be at the same heights.

"The conductive members are inserted into the housing after being held in the holder in advance. Thus, insertion operability into the housing can be improved. Operability is improved further since the holder holds the conductive members and the electronic component at the time of welding. Further, the first conductive member includes the bent portion and the second conductive member maintains its vertical height so that the heights of the electronic component connecting portions are aligned. Therefore, the electronic component connecting portions are connected more easily to the electronic component.

"The holder may include an insertion portion into which the first and second conductive members are insertable. The holder press-fit portion of the first conductive member may project from a center or intermediate position of the coupling substantially in parallel to the electronic component connecting portion at a side opposite to the terminal portions and press-fit into a holder press-fit hole formed in a back of the insertion portion.

"By adopting such a configuration, the first conductive member including the bent portion is fixed to the holder by press-fitting the separately formed holder press-fit portion from the electronic component connecting portion including the bent portion. Thus, no pressing load is applied in the vicinity of the bent portion. Further, since the holder press-fit portion is present in the center or intermediate position of the coupling portion, the influence of displacements caused by tolerances can be reduced.

"The holder may include an insertion portion for receiving the first and second conductive members. A through hole for receiving the bent portion and the first welding portion and an insertion hole for receiving the electronic component connecting portion of the second conductive member may be formed adjacent to each other in a width direction in the holder. A part between the through hole and the insertion hole may be thin, and the electronic component connecting portion of the second conductive member may include the holder press-fit portion to be press-fitted into the insertion hole.

"The above-described configuration provides a relatively large through hole to insert the bent portion and the first welding portion of the first conductive member. The part between through hole and the insertion hole and adjacent to the through hole in the width direction receives the electronic component connecting portion of the second conductive member and is thin. Thus, it is difficult to provide a holder press-fit portion shaped like the holder press-fit portion of the first conductive member and to provide a hole in the thin portion between the through hole and the second connecting portion insertion hole for receiving the holder press-fit portion. Accordingly, the holder press-fit portion is provided on the electronic component connecting portion of the second conductive member and is press-fit into the insertion hole. Therefore, the second conductive member can be press-fit and fixed without enlarging the holder. Further, molding is easier since it is not necessary to form a hole in the thin portion.

"These and other objects, features and advantages of the invention will become more apparent upon reading the following detailed description of preferred embodiments and accompanying drawings.
