Description

The present invention relates to floating connectors, connectors and floating connector assemblies.

The floating connector is used when the mounting positions of the cables and the boards are likely to be misaligned when the cables and the boards are electrically connected or when the boards are electrically connected. As this type of floating connector, there is a fixed housing fixed on a substrate, a movable housing movable relative to the fixed housing, and contacts held across both the fixed housing and the movable housing. and (see, for example, Patent Document 1).

A floating connector fits a mating connector into a movable housing. When mating the mating connector to the movable housing, even if the position of the mating connector is slightly misaligned with the movable housing, the elastic deformation of the contacts moves the movable housing and absorbs the misalignment. do. Therefore, mutual fitting is possible even if there is a slight positional deviation between the mounting positions. A contact generally has a bent portion that is bent so as to be easily elastically deformed.

Plug connector positioning portions 66 are formed at both left and right ends on the front side of the body portion 61 . The plug connector positioning portion 66 is formed in a rectangular parallelepiped shape protruding outward from the left and right ends of the body portion 61 on the front side. The upper portion of the plug connector positioning portion 66 is formed in a semicircular shape when viewed in the left-right direction. The apex of the plug connector positioning portion 66 protrudes slightly upward from the upper surface of the body portion 61 .

As shown in FIGS. 15 to 18, the lower surface of the body portion 61 is formed with a projecting portion 67 projecting downward and extending in the front-rear direction. As shown in FIG. 10 , the protruding portion 67 is formed to have a length from the rear of the detachment prevention projection 46 to the front of the base portion 43 in the front-rear direction. The projecting portions 67 are formed on both left and right sides of each contact accommodating portion 65a, and are formed in plurality at predetermined intervals in the left-right direction. The height of the projecting portion 67 is greater than or equal to the height of the base portion 43 . The insertion portion 62 is formed in a rectangular parallelepiped shape, extends in the front-rear direction at lower portions of the left and right end surfaces of the main body portion 61, and protrudes in the left-right outer direction. The movable-side housing 32 is installed on the fixed-side housing 31 with the insertion portions 62 inserted into the grooves 48 of the left and right walls 42 of the fixed-side housing 31 . At that time, the projecting portion 44 of the fixed-side housing 31 is positioned below between the plug contact connection portions 63 , 63 in the movable-side housing 32 . In addition, the movable housing 32 is slidable (relatively movable) in the front, rear, left, and right directions with respect to the fixed housing 31 .

The receptacle contact 33 is formed into a predetermined shape as shown in FIG. 7 and the like by pressing (punching and bending) a thin flat plate made of a conductive material such as metal. The receptacle contact 33 includes a press-fitting portion 71 (movable-side contact first connection portion, receiving leg) press-fitted and held in the contact holding portion 65b, and a pair of contacted portions 72 that hang down from the front end of the press-fitting portion 71 and extend vertically. , 72 (movable-side contact first connection portion, receiving leg), a spring portion 73 (contact leg) extending rearward from the rear end of the press-fitting portion 71 , and a spring portion 73 formed at its rearward tip end. , and a sliding contact portion 74 (moving side contact second connection portion, contact leg) that slides on the sliding contact portion 53 .

The press-fit portion 71 is bifurcated from the rear side toward the front side and divided into left and right. The press-fitting portion 71 is press-fitted into contact holding portions 65b formed on the left and right sides of the groove-shaped plug contact connection portion 63 so that the front thereof is open. The pair of contacted portions 72 , 72 hang down from the front end portions of the left and right press-fit portions 71 that are bifurcated. The contacted portions 72 , 72 hang down from the front surface of the main body portion 61 of the movable housing 32 and are exposed to the outside of the movable housing 32 . A receiving space in which the contact portion 22a of the plug contact 22 is received is formed between the pair of contacted portions 72, 72. As shown in FIG. Convex portions 75, 75 protruding inward in the left-right direction are formed at the lower tip portions of the contacted portions 72, 72, respectively. The upper side of the convex portion 75 is formed in an inclined shape protruding inward in the left-right direction as it goes downward. The left and right convex portions 75, 75 are formed to face each other, and the distance between them is such that the contact portion 22a of the plug contact 22 can be sandwiched therebetween. That is, the distance between the left and right projections 75, 75 (the distance between the projections 75, 75) is set to be smaller than the thickness of the contact portion 22a in the normal state (the state in which the contact portion 22a is not inserted). When the contact portion 22a is inserted, it is spread by the contact portion 22a. When connecting the plug housing 21 to the movable housing by fitting it vertically, the contact portion 22a of the plug contact 22 is press-fitted into the receiving space of the contact portions 72, 72, and the contact portions 72, 72 are , and the contact portion 22a of the plug contact 22 so as to be vertically slidable.

As shown in FIG. 9, the spring portion 73 includes a first hanging portion 73a hanging down from the press-fitting portion 71 and an intermediate portion 73b extending rearward and upward from the lower tip of the first hanging portion 73a. , and a second hanging portion 73c extending rearward and obliquely downward from the rear tip portion of the intermediate portion 73b. A sliding contact portion 74 is formed at the rear end of the second hanging portion 73c. The spring portion 73 biases the sliding contact portion 74 in the direction of contacting the sliding contact portion 53 of the connection piece 51 when the sliding contact portion 74 is brought into contact with the sliding contact portion 53 of the connection piece 51 from above. The sliding contact portion 74 is in contact with the contact surface 53 a of the slidable contact portion 53 . The receptacle contact 33 configured in this manner is fixed to the movable housing 32 with the press-fit portion 71 holding the contact holding portion 65b of the movable housing 32 . When the movable-side housing 32 is installed on the fixed-side housing 31, the elastic deformation (biasing) of the spring portion 73 causes the sliding contact portion 74 of the receptacle contact 33 and the contact surface 53a of the sliding contact portion 53 to move. , is maintained, and the sliding contact portion 74 faces the sliding contact portion 53 in the vertical direction and is slidably connected in the front, rear, left, and right directions.

Connection between the receptacle connector 3 and the plug connector 2 configured in this manner will be described. First, the plug connector 2 is arranged so that the contact portions 22 a of the plug contacts 22 of the plug connector 2 are positioned above the plug contact connecting portions 63 of the movable housing 32 of the receptacle connector 3 . Then, the plug connector 2 is lowered and brought closer to the receptacle connector 3. Then, the plug connector positioning portion 66 of the receptacle connector 3 is inserted into the positioning recess 26 of the plug connector 2 .

At this time, since the positioning recess 26 is formed in a tapered shape narrowing upward, the front, rear, left, and right positions of the movable housing 32 in the receptacle connector 3 with respect to the plug connector 2 are finely adjusted. At this time, the contact portion 22a of the plug contact 22 is inserted into the plug contact connecting portion 63 of the movable housing 32 of the receptacle connector 3 from above. Since the plug contact connecting portion 63 is tapered on the left, right, and rear sides of the upper portion, when the plug contact 22 is inserted, the position of the movable housing 32 with respect to the plug connector 2 changes slightly in the front, back, left, and right directions. adjustments are made.

When the position of the movable housing 32 with respect to the plug connector 2 is adjusted, the movable housing 32 slides forward, backward, leftward, and rightward with respect to the fixed housing 31 . At this time, the receptacle contact 33 and the connection piece 51 are electrically connected by the sliding contact portion 74 of the receptacle contact 33 coming into sliding contact with the sliding contact portion 53 of the connection piece 51 fixed to the fixed housing 31 . As a result, electrical connection between the receptacle contacts 33 and the wiring pattern of the second substrate 11 is maintained.

When the contact portion 22a of the plug contact 22 is inserted into the plug contact connection portion 63 in the vertical direction by a certain amount or more, the contact portion 22a contacts the convex portion 75 of the contacted portion 72 of the receptacle contact 33 . At this time, since the upper side of the convex portion 75 is formed in an inclined shape, the contact portion 22a is smoothly inserted between the convex portions 75,75. At this time, the contacted portion 72 expands, and the interval between the convex portions 75, 75 widens according to the contact portion 22a. The plug contact 22 contacts the receptacle contact 33 and is electrically connected to the receptacle contact 33 with the contact portion 22a sandwiched between the left and right convex portions 75, 75. As shown in FIG. Since the distance between the left and right projections 75, 75 of the receptacle contact 33 is smaller than the thickness of the contact portion 22a of the plug contact 22, when the contact portion 22a is inserted between the projections 75, 75, A force acts in the direction in which the projections 75, 75 sandwich the plug contact 22, and the receptacle contact 33 and the plug contact 22 are preferably connected. Thus, the plug connector 2 and the receptacle connector 3 are electrically connected, and the first board 10 and the second board 11 are electrically connected.

The contact portion 22a of the plug contact 22 is connected to the receptacle contact 33 so as to be sandwiched between the projecting portions 75 of the contacted portion 72 of the receptacle contact 33 in the left-right direction. The contact portion 22a of the plug contact 22 has a predetermined width in the vertical direction. Therefore, even if the contact portion 22a moves vertically relative to the plug contact connection portion 63, the connection between the contact portion 22a and the receptacle contact 33 is maintained. Therefore, when connecting the plug connector 2 to the receptacle connector 3, even if the vertical position of the plug connector 2 with respect to the receptacle connector 3 is slightly shifted, the plug contacts 22 and the receptacle contacts 33 can be connected. A receptacle connector 3 can be connected.

The movable-side housing 32 can move relative to the fixed-side housing 31 in the front, rear, left, and right directions. The connection piece 51 installed on the fixed housing 31 is formed with a contact surface 53a extending in the front, rear, left, and right direction. 74 are in sliding contact with each other, the connection between the receptacle contact 33 and the contact surface 53a is maintained even if the movable housing 32 moves back and forth and right and left. Therefore, even if the position of the plug connector 2 deviates from the receptacle connector 3 in the front-rear direction or the left-right direction when connecting the plug connector 2 to the receptacle connector 3, the deviation can be absorbed.

In the receptacle connector 3 thus formed, when the movable housing 32 slides relative to the fixed housing 31, the receptacle contacts 33 fixed to the movable housing 32 are fixed to the fixed housing 31. Since the connection piece 51 is kept in sliding contact with the connection piece 51, the receptacle contact 33 does not need to be bent in a large vertical direction so as to be elastically deformable in the front-rear direction. can be reduced, and a low-profile receptacle connector 3 can be obtained.

Further, in this connector assembly 1, since the plug contact connection portion 63 is opened not only upwardly but also forwardly, the plug contact 22 projecting in the longitudinal direction can be inserted, and the plug connector 2 and the receptacle connector 3 can be moved forward and backward. Can be connected side by side. Therefore, this connector assembly 1 can be of a low profile type. Further, in this connector assembly 1, since the plug contact connection portion 63 is open not only at the front but also at the top, it is possible to connect the plug connector 2 so as to overlap the receptacle connector 3 from above. The present invention can be applied even in a manufacturing site with no vacant space.

It should be noted that the present invention is not limited to the above-described embodiments, and can be modified as appropriate without departing from the gist of the present invention.

In the above embodiment, the horizontal connection type connector assembly 1 in which the two substrates (the first substrate 10 and the second substrate 11) are arranged and connected to each other in the front-rear direction was exemplified and explained, but it is not limited to this configuration. The present invention may also be applied to a vertical connection type connector assembly in which both substrates are arranged at right angles to each other and electrically connected, or a connector assembly in which both substrates are connected so as to overlap each other in parallel.

In the above embodiment, the plug connector 2 or the receptacle connector 3 has been described as a board-mounted connector, but the plug connector 2 or the receptacle connector 3 may be various connectors such as a cable-mounted connector. Although the plug contact 22 is exposed from the plug housing 21 in the vertical direction and the rearward direction in the above embodiment, it is sufficient that the plug contact 22 is exposed at least in the vertical direction.
