  • Patent number: 10931037
    Abstract: A dual contact Insulation Displacement Contact (IDC) header pin comprised of an upper section, a lead-in section, and a retention section. The upper section of the pin has at a plurality of pin barbs to allow it to be retained into a housing. The side walls and back of the upper portion create a C-shape to the upper portion. Each IDC header pin has two blades to contact a wire and displace the insulation thereof. The lead-in section serves to lead the IDC header pin into a housing and prevent stubbing of the pin during insertion. The retention section of the pin has a plurality of rib-like projections allowing the pin to be retained into respective holes in a PCB by applying normal force and an interference fit. An embodiment is open, with front protrusions on the upper section, and another embodiment is closed, having two front walls on the upper section.

  • Patent number: 10923847
    Abstract: A male terminal position assurance (TPA) device for a male connector assembly, preferably for a high voltage connector assembly. The male TPA has a substantially wing-like shaped upper member that respectively locks terminals inside a male inner housing, and further has a flexible arm member, in a lower member thereof, that locks the male TPA device in the male inner housing. The male TPA device does not lock inside the male inner housing if it detects that the corresponding terminal has not been fully inserted or installed into the male inner housing. The male inner housing includes a primarily lock for locking the terminal, while the male TPA device, when in full-lock position, provides for a secondary lock for locking the terminal inside the inner housing. When in the full-lock position inside the male inner housing, the male TPA device assures that the necessary retention forces are provided to ensure that the terminal remains fully locked within the male connector assembly.

  • Patent number: 10916884
    Abstract: Method of operating a connector latch used to securely hold together a connector apparatus, wherein the connector apparatus has at least a first housing and a second housing which can be mated together. Initially, after the connector latch is manufactured, the connector latch is in an undeflected position. After manufacture, the connector latch is subjected to a pre-mating deflection process, in order to deflect the connector latch into a preloaded position. After the pre-mating deflection process has been completed, the connector latch is locked in the preloaded position. The preloaded connector latch provides a number of desirable characteristics, including at least an extra loud “click” sound when the connecting latch is operated to mate the first housing with the second housing.

  • Patent number: 10906277
    Abstract: A problem addressed by the present invention is to provide a low-friction member which does not easily lose low-friction properties thereof even when used for a relatively long period. The low-friction member LS according to the present invention is consisting of at least lubricating materials PL, PS and a polyimide resin MR. The low-friction member has a surface roughness Rsk or 0.500 or more and the surface exposure ratio of the lubricating materials of 15.0% or more. It is particularly preferred that the surface roughness Rsk be in a range of 0.0900 (inclusive) to 0.1400 (inclusive), and the surface exposure ratio of the lubricating materials be 35.0% or more. It is preferred that the lubricating materials be a fluororesin. The low-friction member thus has the property of not losing the low-friction properties thereof easily even when used for a relatively long period.

  • Patent number: 10903588
    Abstract: Each IDCC header pin is comprised of an upper section, a pin barb section, and a lower section. Each IDCC header pin has at least a first pin barb on its pin barb section, to allow it to be anchored and retained into a housing. The upper section of each IDCC header pin also has a blade to contact a wire and displace the insulation thereof. The lower section of the pins has an associated compliant retention feature which allows the IDCC header pin to be retained into respective holes in a PCB. A dual contact bent IDCC header pin can include two upper sections which each have a blade and create a dual contact with a wire, and another embodiment can have a two-thickness upper section.

  • Patent number: 10892579
    Abstract: A female terminal position assurance (TPA) device provides essential secondary locks resulting in much higher retention forces in assuring that the terminals remain locked inside a female housing. The female TPA device also provides the needed detection if the terminals are not fully inserted or installed inside the female housing so that if such a detection is made, the secondary locks provided by the female TPA device do not occur. That is, once it is detected that the terminals have been fully inserted into the female housing and that the primary locks for the terminals inside the female housing have occurred, the female TPA device is able to be inserted into the female housing and thereby provide the secondary locks for the terminals for a much higher assurance that the terminals remain locked inside the female housing. The female TPA device further includes multiple locks with the female housing, while the female TPA device is in a pre-lock position or a full-lock position inside the female housing.

  • Patent number: 10855025
    Abstract: A connector position assurance device having multiple features for assuring a full coupling and locking of a female housing with a male housing in a connector system, such that the female housing and male housing are placed into a fully coupled and locked position when the connector position assurance device is moved from a pre-lock position to a full-lock position. When the connector position assurance device is at a full-lock position, a first member on the connector position assurance penetrates a window formed on the female housing, and at least one ledge extending from the connector position assurance device prevents a flexible member of the female housing from being moved downward, providing assurance that the female and male housings are fully coupled and locked together.
