Description
4~69 ~,0?~940 This invention relates to an electrical connector housing.
In Canadian Patent Mo. 911558 there is described and claimed an electrical connector housing formed of electrically insulating material and having a contact-receiving cavity open at both ends, there being a shoulder at one end of the cavity for preventing insertion or withdrawl of a contact through that one end of the cavity, and a portion of one wall of the housing being formed as a flap integral with the remainder of the one wall of the housing only at a hinge extending trans-versely of the longitudinal axis of the cavity, the flap carrying a boss providing a second shoulder which, with the ~lap in an open position, is clear of the cavity to permit insertion or withdrawal of a contact through the other end of the cavity, and, with the flap in a closed position, extends into the cavity to prevent withdrawal of an inserted contact through the other end of the cavity, the flap and the remainder of the housing being provided with co-operating releasable latching m~ans which serve to secure the flap in the closed position.
In such a connector housing, hereinafter referred to 2S being of the type specified, the flap and second shoulder arrangement serves to permit easy insertion into, and positiv2 retention of a contac~ in, the cavity, the second shoulder possibly serving as retention means add-itional to any other retention means provided, for example, a lance on the contact, which co-operates with a further shoulder in the cavity.
The second shoulder of such a connector housing ~, .
` 4669 ~7~940 ;
serves the furthex advantageous function of ensuring that an inserted contact is correctly received in the cavity, it being impossible to close the flap if the contact is not inserted far enough into the cavity.
In the known connector housing the flap extends from the hinge towards, and in fact up to, the other end of the cavity, that is the end of the cavity remote from the first shoulder, and latches to the remainder of the housing at the free end of the flap.
Thus, in use, a wire connected to a contact contained in the cavity leaves the cavity by the end thereof at which the latching means is provided, and it can happen that if the wire is pulled transversely of the axis of the cavity towards and against the flap, then the flap becomes un-latched with consequential loss of the security of reten-tion of the contact in the cavity.
According to this invention, in a connector housing of the type specified the second shoulder is provided at the free end of the flap, and the flap extends from the hinge towards the one end of the cavity at which the first shoulder is located, the hinge being spaced from the other end of the cavity.
Thus, with the connector housing of this invention any movement of a wire connected to a contact contained in the cavity, transversely of the axis of the cavity to-wards the flap, will bring the wire into contact with a solid portion of the housing and not the free end of the flap, and the flap will not therefore be opened but will remain in the latched closed, contact-retaining position.
An electrical connector housing according to this ~:)7~940 invention will now be described by way of example with re~erence to the drawings, in which:-Figure 1 is a perspective view of the housing, and Figure 2 is a longitudinal sectional view through a cavity of the housing of Figure 1, with a contact inthe cavity.
The housing is moulded from electrically insulating material and has three contact-receiving cavities 1 each open at both ends. The housing has a pair of latching arms 2 by which the housing can be secured to a mating housing 101 (Figure 2) in known manner.
Shoulders 3 are formed at one end 4 of each cavity 1 for preventing insertion or withdrawal of a contact 5 (Figure 2) to be retained in the cavity 1, through the one end 4 of the cavity 1, while permitting entry of a contact 100 contained in the mating housing 101 (Figure 2) to mate with the contact 5.
A portion of one wall of the housing is formed as a flap 6 integral with the remainder of the wall only at a hinge 7 extending transversely of the longitudinal axis of the cavities 1.
The flap 6 carries three bosses ~ each providing a second shoulder 9 which, with the flap 6 in an open pos-ition as shown in Figure 1, ls clear of an individual one of the cavities 1 to permit insertion or withdrawal of the ~icontact 5 through the other end 10 of the cavity 1. With the flap 6 in a closed position as shown in Figure 2, each shoulder 9 extends into the associated cavity 1 to lie behind the contact 5 in the cavity 1, and prevent withdrawal of the contact 5 through the other end 10 of the cavity 1.
The contact 5 also has, in known manner, a lance 11 which co-operates with a further shoulder 12 in the cavity 1 to prevent withdrawal of the contact 5 through the other end 10 of the cavity 1.
S The contact S is thus secured in the cavity 1 by engagement between the shoulders 3 and 12, with additional security being provided by the shoulders 9 when the flap 6 is in its closed position (Figure 2).
The flap 6 is provided at each side adjacent its free end with latching means 13 of known form, which co-operate with latching means 14 on the remainder of the housing, to secure the flap 6 in its closed position shown in Figure 2.
As shown, the bosses 8, and thus the second shoulders 9, are provided at the free end of the flap 6, and the flap 6 extends from the hinge 7 towards the one end 4 of each cavity 1. Further, the hinge 7 is spaced from the :~
other end 10 of each cavity 1 by a rigid wall portion 15.
Thus, any movement of a wire 102 (Figure 2) connec-ted to the contact 100 contained in a cavity 1, trans-versely of the axis of the cavity 1 towards the flap 6, will bring the wire 102 into contact wtih the wall portion 15, and the flap 6 will not be opened by such movement.
Although the housing described above has three contact-receiving cavities it will be appreciated that a housing according to this invention can have any number of cavities. In a housing with a large number of cavi-ties and thus with a wide flap, additional latching means to secure the flap in its closed position can be provided intermediate the edges of the flap.
107~940 Further, it will be appreciated that the type of contact to be contained in the or each cavity of a housing according to this invention is not c~itical, save that the contact can engage the first and second shoulders (3 and 9) of the housing as described above.
In Canadian Patent Mo. 911558 there is described and claimed an electrical connector housing formed of electrically insulating material and having a contact-receiving cavity open at both ends, there being a shoulder at one end of the cavity for preventing insertion or withdrawl of a contact through that one end of the cavity, and a portion of one wall of the housing being formed as a flap integral with the remainder of the one wall of the housing only at a hinge extending trans-versely of the longitudinal axis of the cavity, the flap carrying a boss providing a second shoulder which, with the ~lap in an open position, is clear of the cavity to permit insertion or withdrawal of a contact through the other end of the cavity, and, with the flap in a closed position, extends into the cavity to prevent withdrawal of an inserted contact through the other end of the cavity, the flap and the remainder of the housing being provided with co-operating releasable latching m~ans which serve to secure the flap in the closed position.
In such a connector housing, hereinafter referred to 2S being of the type specified, the flap and second shoulder arrangement serves to permit easy insertion into, and positiv2 retention of a contac~ in, the cavity, the second shoulder possibly serving as retention means add-itional to any other retention means provided, for example, a lance on the contact, which co-operates with a further shoulder in the cavity.
The second shoulder of such a connector housing ~, .
` 4669 ~7~940 ;
serves the furthex advantageous function of ensuring that an inserted contact is correctly received in the cavity, it being impossible to close the flap if the contact is not inserted far enough into the cavity.
In the known connector housing the flap extends from the hinge towards, and in fact up to, the other end of the cavity, that is the end of the cavity remote from the first shoulder, and latches to the remainder of the housing at the free end of the flap.
Thus, in use, a wire connected to a contact contained in the cavity leaves the cavity by the end thereof at which the latching means is provided, and it can happen that if the wire is pulled transversely of the axis of the cavity towards and against the flap, then the flap becomes un-latched with consequential loss of the security of reten-tion of the contact in the cavity.
According to this invention, in a connector housing of the type specified the second shoulder is provided at the free end of the flap, and the flap extends from the hinge towards the one end of the cavity at which the first shoulder is located, the hinge being spaced from the other end of the cavity.
Thus, with the connector housing of this invention any movement of a wire connected to a contact contained in the cavity, transversely of the axis of the cavity to-wards the flap, will bring the wire into contact with a solid portion of the housing and not the free end of the flap, and the flap will not therefore be opened but will remain in the latched closed, contact-retaining position.
An electrical connector housing according to this ~:)7~940 invention will now be described by way of example with re~erence to the drawings, in which:-Figure 1 is a perspective view of the housing, and Figure 2 is a longitudinal sectional view through a cavity of the housing of Figure 1, with a contact inthe cavity.
The housing is moulded from electrically insulating material and has three contact-receiving cavities 1 each open at both ends. The housing has a pair of latching arms 2 by which the housing can be secured to a mating housing 101 (Figure 2) in known manner.
Shoulders 3 are formed at one end 4 of each cavity 1 for preventing insertion or withdrawal of a contact 5 (Figure 2) to be retained in the cavity 1, through the one end 4 of the cavity 1, while permitting entry of a contact 100 contained in the mating housing 101 (Figure 2) to mate with the contact 5.
A portion of one wall of the housing is formed as a flap 6 integral with the remainder of the wall only at a hinge 7 extending transversely of the longitudinal axis of the cavities 1.
The flap 6 carries three bosses ~ each providing a second shoulder 9 which, with the flap 6 in an open pos-ition as shown in Figure 1, ls clear of an individual one of the cavities 1 to permit insertion or withdrawal of the ~icontact 5 through the other end 10 of the cavity 1. With the flap 6 in a closed position as shown in Figure 2, each shoulder 9 extends into the associated cavity 1 to lie behind the contact 5 in the cavity 1, and prevent withdrawal of the contact 5 through the other end 10 of the cavity 1.
The contact 5 also has, in known manner, a lance 11 which co-operates with a further shoulder 12 in the cavity 1 to prevent withdrawal of the contact 5 through the other end 10 of the cavity 1.
S The contact S is thus secured in the cavity 1 by engagement between the shoulders 3 and 12, with additional security being provided by the shoulders 9 when the flap 6 is in its closed position (Figure 2).
The flap 6 is provided at each side adjacent its free end with latching means 13 of known form, which co-operate with latching means 14 on the remainder of the housing, to secure the flap 6 in its closed position shown in Figure 2.
As shown, the bosses 8, and thus the second shoulders 9, are provided at the free end of the flap 6, and the flap 6 extends from the hinge 7 towards the one end 4 of each cavity 1. Further, the hinge 7 is spaced from the :~
other end 10 of each cavity 1 by a rigid wall portion 15.
Thus, any movement of a wire 102 (Figure 2) connec-ted to the contact 100 contained in a cavity 1, trans-versely of the axis of the cavity 1 towards the flap 6, will bring the wire 102 into contact wtih the wall portion 15, and the flap 6 will not be opened by such movement.
Although the housing described above has three contact-receiving cavities it will be appreciated that a housing according to this invention can have any number of cavities. In a housing with a large number of cavi-ties and thus with a wide flap, additional latching means to secure the flap in its closed position can be provided intermediate the edges of the flap.
107~940 Further, it will be appreciated that the type of contact to be contained in the or each cavity of a housing according to this invention is not c~itical, save that the contact can engage the first and second shoulders (3 and 9) of the housing as described above.
