The present disclosure generally relates to an electrical wiring connector, and more particularly to a connector with reduced insertion forces.
Traditionally, electrical connectors can be used to couple, join or electrically connect various electrical components together to enable data, current, etc. to flow between the electrical components. For example, an electrical component can include one or more electrical wires, which can be joined together at a terminal. The terminal can be configured to mate with a corresponding terminal, in a male-female fashion. The electrical connector can facilitate the engagement of the male terminal with the female terminal, and the electrical connector can be configured to resist the disengagement of the female terminal with the male terminal.
Generally, in-line electrical connectors can be used in motor vehicles due to their compact size. A typical in-line connector can include a male housing that can surround a male terminal, and a female housing that can surround a female terminal. Typically, in order to engage the male housing with the female housing with this type of in-line connector, an operator has to use some force to push the female housing into the male housing, which can cause operator fatigue over time.
A connector is provided. The connector can include a first housing, which can define a bore for receipt of at least one first electrical terminal. The first housing can include a first wall opposite a second wall. The first wall can define an aperture, and the first housing can have a longitudinal axis. The connector can include a second housing, which can define a bore for receipt of at least one second electrical terminal. The bore can be sized such that the second housing can fit over a portion of the first housing. The second housing can include a first wall opposite a second wall. The first wall can include a first engagement feature. The connector can include a first rotatable element that can be coupled to the first housing and retained within the aperture of the first wall. The first rotatable element can include a first feature that engages the first engagement feature of the first wall of the second housing, and a second feature. The connector can include a mechanical assist, which can include at least one assist feature. The at least one assist feature can engage the second feature of the first rotatable element so that movement of the mechanical assist in a direction parallel to the longitudinal axis of the female housing can cause the first rotatable element to rotate and draw the at least one first electrical terminal into contact with the at least one second electrical terminal.
Further provided is a connector. The connector can include a female housing, which can define a bore for receipt of at least one female electrical terminal. The female housing can include a top wall opposite a bottom wall, and each of the top wall and the bottom wall can define an aperture. The connector can include a male housing, which can define a bore for receipt of at least one male electrical terminal. The bore can be sized such that the male housing can fit over a portion of the female housing. The male housing can include a top wall opposite a bottom wall, and each of the top wall and the bottom wall can include an engagement feature. The connector can include a first rotatable element, which can be rotatably coupled to the aperture of the top wall of the female housing. The first rotatable element can include a first feature that engages the engagement feature of the top wall of the male housing, and a second feature. The connector can include a second rotatable element, which can be rotatably coupled to the aperture of the bottom wall of the female housing. The second rotatable element can include a third feature that engages the engagement feature of the bottom wall of the male housing, and a fourth feature. The connector can include a mechanical assist, which can include a first assist feature. The first assist feature can engage the second feature of the first rotatable element. The mechanical assist can include a second assist feature, which can engage the fourth feature of the second rotatable element so that movement of the mechanical assist relative to the female housing can rotate the first rotatable element and the second rotatable element to draw the at least one female electrical terminal into contact with the at least one male electrical terminal.
In one of various embodiments, a connector is provided. The connector can include a female housing, which can define a bore for receipt of at least one female electrical terminal. The female housing can include a top wall opposite a bottom wall, a proximal end and a distal end. Each of the top wall and the bottom wall can define an aperture and can include a rail formed at the distal end. The connector can include a male housing, which can define a bore for receipt of at least one male electrical terminal. The bore can be sized such that the male housing can fit over a portion of the female housing. The male housing can include a top wall opposite a bottom wall, and each of the top wall and the bottom wall can include a projection. The connector can include a first rotatable element rotatably coupled to the aperture of the top wall of the female housing. The first rotatable element can include a top surface that extends beyond a surface of the female housing and can define a slot and a groove that slidably receives the projection of the top wall of the male housing. The first rotatable element can also include a bottom surface that retains the first rotatable element within the aperture. The connector can include a second rotatable element rotatably coupled to the aperture of the bottom wall of the female housing. The second rotatable element can include a top surface that extends beyond a surface of the female housing and defines a second slot and a second groove that slidably receives the projection of the bottom wall of the male housing. The second rotatable element can include a bottom surface that retains the second rotatable element within the aperture. The connector can include a mechanical assist, which can include a first pin that engages the slot of the first rotatable element, a second pin opposite the first pin that engages the second slot of the second rotatable element, a first guide that engages the rail of the top wall and a second guide that engages the rail of the bottom wall. The mechanical assist can be slidable on the rails of the female housing to draw the at least one female electrical terminal into contact with the at least one male electrical terminal.

The bottom wall 38 can include a first or outer surface 38a, a second or inner surface 38b and an aperture 38c. The outer surface 38a can include a rail 48. The rail 48 can cooperate with the mechanical assist 16 to couple the male housing 12 to the female housing 14. Generally, the rail 48 can extend along a longitudinal axis of the outer surface 38a, adjacent to the distal end 42 of the female housing 14. The inner surface 38b can define a groove 50. The groove 50 can guide the rotation of a respective one of the rotators 14c within the aperture 38c, and thus, can enable the aperture 38c to move relative to the bracket 14b without the removal of the rotator 14c from the bracket 14b. The aperture 38c can be formed generally about the central axis C of the bracket 14b. The aperture 38c can be sized to enable a respective one of the rotators 14c to move relative to the bracket 14b, upon receipt of an input from the mechanical assist 16, as will be discussed herein.
The proximal end 40 can be configured to mate with the male housing 12, and can be sized to be received within the bore 30 of the male housing 12. Generally, the set of female terminals 14a can be positioned within the bracket 14b between the proximal end 40 and the distal end 42 such that the set of male terminals 12a can be inserted into the set of female terminals 14a to facilitate electrical communication between the set of male terminals 12a and the set of female terminals 14a. The distal end 42 can include the rails 44, 48, which can cooperate with the mechanical assist 16 to assist the operator in securing the male housing 12 to the female housing 14.

The bottom surface 56 can include a wedge 56a. The wedge 56a can have a thickness sized to enable a lip 64 formed along an edge 56b of the wedge 56a to slidably engage the groove 46, 50 of the inner surface 36b, 38b of the bracket 14b. Thus, the lip 64 can cooperate with the groove 46, 50 to retain the rotators 14c within the bracket 14b. Generally, the wedge 56a can be coupled to the bottom surface 56 at a location opposite the slot 58, and underneath the groove 60. Thus, the rotators 14c can be slidably retained within the bracket 14b and can move the female housing 14 relative to the male housing 12, via the mechanical assist 16.

The sidewalls 16b can be coupled to the top wall 16a. The sidewalls 16b can each include a guide 74 and an assist feature, such as a projection or pin 76. The guide 74 can extend outwardly from the sidewall 16b, and can define a slot 74a. The slot 74a can be sized to slidably receive the rails 44, 48 to enable the mechanical assist 16 to move along the rails 44, 48, relative to the bracket 14b. Generally, the slot 74a can include a stop 74b, which can prevent the further advancement of the mechanical assist 16 once the mechanical assist 16 is moved from the first position (
With reference to
Thus, with reference to
Then, with the mechanical assist 16 in a pre-set position in which the pins 76 are engaged with the slot 58 of the rotators 14c and the guides 74 engaged with the rails 44, 48, the mechanical assist 16 can be moved by the operator in a direction parallel to the longitudinal axis of the bracket 14b, along the rails 44, 48. The movement of the mechanical assist 16 can rotate the rotators 14c within the apertures 36c, 38c, which can cause the first male projection 26 and second male projection 28 to move within the groove 60. Due to the arcuate shape of the groove 60, the movement of the first male projection 26 and second male projection 28 within the groove 60 can draw the set of female terminals 14a into electrical contact with the set of male terminals 12a as the mechanical assist 16 moves from the first position (
