The present invention generally relates to a connector position assurance (CPA) member which can be used with a female housing and a male housing.
The present invention generally relates to a connector position assurance (CPA) member which can be used in conjunction with a female connector assembly and a male connector assembly. The female connector assembly includes at least a female housing and the CPA member. The male connector assembly includes at least a male housing. The female connector assembly and male connector assembly can be mated together.
The CPA member of the present invention provides a benefit by assuring the engagement of the male housing with the female housing. The female housing further includes a connector latch used to securely hold the electrical connector apparatus together.
A terminal position assurance (TPA) member can be inserted into the female housing for assuring that terminals for the electrical connector apparatus are positioned properly.
An electrical connector apparatus, having the female housing of the present invention, a male housing, the CPA member of the present invention, and the connector latch of the present invention, demonstrates a number of desirable characteristics. For example, one of the desirable characteristics is that the CPA member and female housing of the present invention can be used with existing male housings without requiring changes to the male inline and/or header.
Also, one of the desirable characteristics is that the CPA member and female housing of the present invention can be used with existing male housings without requiring changes to the overall shape of the male housings.
There are some existing male housings that do not currently have the benefit of a highly effective CPA member. That is, those existing male housings do not have a configuration that accommodates a highly effective CPA member. Thus, those existing male housings do not have the beneficial assurance of the engagement of the male housing with a female housing provided by a highly effective CPA member.
According to the principles of the present invention as disclosed herein, at least some internal aspects of a female housing have been modified in order to accommodate a highly effective CPA member, while at least some external aspects of the female housing have not been modified. Because of the external aspects of the female housing which were not modified, the female housing of the present invention and the highly effective CPA member of the present invention can be used with an existing male housing. Thus, the existing male housing does not need to be modified extensively if at all, and the existing male housing can be used with the female housing of the present invention and the CPA member of the present invention. This is advantageous because existing male housings that previously were not being used with a highly effective CPA member can now have the benefits of being used with such a CPA member.
A female housing has been specially designed and made to have a shape that fits well with existing male housings while also having features, such as apertures and/or slots, that can accommodate a highly effective CPA member.
The CPA member of the present invention is highly effective, and has been specially designed and made to have the shape and features that fit well with the female housing of the present invention and the existing male housings discussed above.
Other desirable characteristics of the present invention are as follows: there is an audible “click” sound when the female connector assembly and the male housing are mated together, which is an extra loud sound; a low profile connector position assurance (CPA) member; a low profile connector latch; a resistance to permanent set for the connector latch; a resistance to movement to final lock position for the CPA member; a moderate amount of reinforcement; mutual retention; good mechanical strength; easy molding features; no secondary operation of a user is required; failure prevention means; and good dimensional control of latching geometry.
To ensure that the CPA member is made available for connecting to the female housing during transport thereof, for example, the CPA member is engaged, in a preset position, to the female housing.
The male housing and female connector assembly are engaged together, and the engagement thereof is assured, when the CPA member is placed in a final lock position.
It is a desirable trait to have an audible “click” sound for an electrical connector. For example, when components of an automotive electrical connector are completely mated with each other, it is a desirable trait to have an audible “click” sound for convenient assurance that the components are completely mated. In the automotive connector field, an extra loud sound is favorable. The “click” sound can be achieved by an interaction of latching features, for example.
By placing latching features in a preloaded condition, there is additional force when a first connector assembly and a second housing are mated together, and that additional force helps to make the “click” sound louder than it would have been if the latching features had not been in a preloaded condition.
It is a desirable trait for the connector latch to have a low profile. By manufacturing the connector latch in an undeflected position, the gaps required to create overstress protection features, to prevent the connector latch from being pried in the wrong direction and damaged, are not needed. The gaps can be removed from the overall height of the latch system, so that the connector latch can have a low profile.
It is a desirable trait to have a resistance to being set. For example, when automotive wire harnesses are bundled for shipment, the connector latches can be unintentionally compressed and held in a deflected position. Especially in hot environments, this condition causes the connector latch to be permanently deflected, also known as permanently set, thus rendering the connector latch useless or less effective. Preloading the connector latch makes the connector latch more resistant to this failure mode.
It is a desirable trait to have good dimensional control of latching geometry. By preloading the connector latch against dimensionally stable features, the height of the connector latch features can be controlled easily.
After the connector latch is manufactured, the connector latch is in an undeflected position. The connector latch is then subjected to a pre-mating deflection process, in order to deflect the connector latch and lock the connector latch in a preloaded position. After the pre-mating deflection process has been completed, the connector latch is locked in a preloaded position and can be referred to as a preloaded connector latch.
When a first connector assembly and a second housing are engaged together, the engagement thereof is assured because the connector latch causes an audible “click” sound. A first connector assembly can be referred to as a connector, and can include at least a first housing and a connector position assurance member, for example. A first connector assembly can correspond to a female connector assembly or other type of connector assembly, for example. A first housing can correspond to a female housing or other type of housing, for example. A second housing can correspond to a male housing or other type of housing, for example. The undeflected position can also be referred to as an extended and relaxed undeflected position.
A CPA member provides a number of desirable characteristics, including at least, for example: it helps to achieve a full potential force of the system and desirable audible “click” sound when the CPA member is inserted into a housing; it helps to avoid a CPA member being moved to a final lock position (or “set” position) during shipping and/or handling; it requires no secondary operation of a user; and it helps prevent failure.
Additional features, advantages, and embodiments of the invention are set forth or apparent from consideration of the following detailed description, drawings and claims. Moreover, it is to be understood that both the foregoing summary of the invention and the following detailed description are exemplary and intended to provide further explanations without limiting the scope of the invention as claimed.
The present invention generally relates to a connector position assurance (CPA) member which can be used in conjunction with a female connector assembly and a male connector assembly. The female connector assembly includes at least a female housing and a connector position assurance (CPA) member. The male connector assembly includes at least a male housing. The female connector assembly and male connector assembly can be mated together.
The highly effective CPA member 200 provides a benefit by assuring the engagement of a male housing 400 with the female housing 100. The female housing 100 further includes a connector latch used to securely hold the electrical connector apparatus together. A terminal position assurance (TPA) member 300 can be inserted into the female housing for assuring that terminals for the electrical connector apparatus are positioned properly, but the TPA member 300 is not required.
An electrical connector apparatus, having the female housing 100 of the present invention, a male housing 400, the CPA member 200 of the present invention, and the connector latch of the present invention, has a number of desirable characteristics. For example, one of the desirable characteristics is that the CPA member and female housing of the present invention can be used with existing male housings without requiring, changes to the male inline and/or header.
Also, one of the desirable characteristics is that the CPA member and female housing of the present invention can be used with existing male housings without requiring changes to the overall shape of the male housings.
There are some existing male housings that do not currently have the benefit of a highly effective CPA member. That is, those existing male housings do not have a configuration that accommodates a highly effective CPA member. Thus, those existing male housings do not have the beneficial assurance of the engagement of the male housing with a female housing provided by a highly effective CPA member.
According to the principles of the present invention as disclosed herein, at least some internal aspects of a female housing have been modified in order to accommodate a highly effective CPA member, while at least some external aspects of the female housing have not been modified. Because of the external aspects of the female housing which were not modified, the female housing of the present invention and the highly effective CPA member of the present invention can be used with an existing male housing. Thus, the existing male housing does not need to be modified extensively if at all, and the existing male housing can be used with the female housing of the present invention and the CPA member of the present invention. This is advantageous because existing male housings that previously were not being used with a highly effective CPA member can now have the benefits of being used with such a CPA member.
A female housing has been specially designed and made to have a shape that fits well with existing male housings while also having features, such as apertures and/or slots, that can accommodate a highly effective CPA member.
The CPA member of the present invention is highly effective, and has been specially designed and made to have the shape and features that fit well with the female housing of the present invention and the existing male housings discussed above.
A full connector assembly can include a male connector assembly and a female connector assembly, for example. The male connector assembly can include a male housing and may also include one or more terminal position assurance (TPA) members and/or one or more connector position assurance (CPA) members. The female connector assembly can include a female housing and may also include one or more terminal position assurance members and/or one or more connector position assurance members.
For example, a female connector assembly may consist of a female housing, an optional TPA member, and a CPA member. In this example, the TPA member and. CPA member are inserted into the female housing in the preset position, for a female sub-assembly. Then, the female sub-assembly is inserted into a male housing.
A male connector assembly, for example, may consist of a male housing and an optional TPA member. In this example, for a male sub-assembly, the optional TPA member is inserted into the male housing in the preset position.
The female and male connector assemblies are generally assembled separately. After inserting terminals in both the female and male connector assemblies, a TPA member can be pushed to the final lock position for providing a secondary locking to the terminals. Both sub-assemblies are then mated to make a full connector assembly.
The female housing has a connector latch which latches with the male housing to interlock. The CPA member provides an assurance that both female and male connector assemblies are locked.
Preliminarily, the CPA member is placed in the female housing in a preset position. Then, when appropriate, the CPA member is pushed to the final lock position (fully locked position, “set” position).
The CPA member of the present invention includes a number of advantages and improvements. The CPA member of the present invention can help to prevent a locking latch from getting damaged/deformed during shipping and handling, and thus can help prevent mating problems.

The CPA member of the present invention facilitates the provision of an improved connector assembly comprising a female housing and the CPA member designed to provide a superior audible click sound, moderate reinforcement, mutual retention, good mechanical strength when the female and male housings engage with each other, and extremely easy molding consideration by manufacturing the female housing's connector latch with overbuild and then pushing the button of the connector latch to a preset position during assembly.
After a female housing is manufactured, according to the principles disclosed herein, the connector latch is in the extended and relaxed undeflected position. When the connector latch is in that position, the button 140 of the connector latch is extended upward, above a top 110 of a female housing 100. The button 140 is held up in the extended and relaxed undeflected position by the latch beams 146 and 148.
As indicated above, after a female housing is manufactured, according to the principles disclosed herein, the connector latch is in the extended and relaxed undeflected position. The connector latch is then subjected to a pre-mating deflection process, in order to deflect the connector latch and lock the connector latch in a preloaded position.
The pre-mating, deflection process for the connector latch can include urging the button 140 downward toward the “T” shaped guide member 128.
After the pre-mating deflection process has been completed, the connector latch is locked in a preloaded position and can be referred to as a preloaded connector latch.
