Description

Connector assembly and board end connector

Technical Field

The present disclosure relates to a connector, and more particularly, to a connector assembly having a snap member and a board end connector.

Background

Connector assemblies have been widely used in various mobile communication devices and personal terminal devices to connect and transmit signals or power between functional devices and a motherboard in such devices. Known connector assemblies typically include a wire end connector and a plate end connector. The connector assembly can be divided into a horizontal insertion mode and a vertical insertion mode according to the insertion direction of the line end connector.

The horizontal insertion mode is that the line end connector is inserted into the board end connector in a direction parallel to the substrate, and the vertical insertion mode is that the line end connector is inserted into the board end connector from top to bottom in a direction perpendicular to the substrate. The horizontal insertion may provide a longer insertion depth and thus a better connection quality, but requires a larger operating space. The vertical insertion method can save the operation space for insertion, but because of the limitation of height, the insertion depth is shorter, so that the quality of connection is not stable.

In the conventional vertical plug-in connector assembly, a buckle is usually disposed on the plastic insulating bodies of the board-side connector and the line-side connector to increase the pull-out force of the line-side connector itself to prevent the line-side connector from being disconnected, but the pull-out force provided by the buckle is limited, and the line-side connector may be disconnected under the condition of gravity acceleration (such as falling onto the ground), which may cause disconnection of the contacts of the signal or power supply.

Furthermore, two stop blocks 1113 are formed on the top end of the base 111 away from the board 114, and a fastening portion 1114 with a slope and a fastening block 1115 disposed on the two side walls of the base are formed on the top of the base 111.

The top surfaces of the two side arms 112 have a height difference with the top surface of the base 111, and a through slot 1121 is concavely formed on the top surface of each side arm 112 along the buckling direction S2. That is, the penetrating grooves 1121 penetrate through opposite sides (upper left side and lower right side in fig. 2) of the insulating housing 11 along the engaging direction S2.

The fastener 13 is a bent and symmetrical sheet structure, and the fastener 13 has an elongated first sheet 131, two second sheets 132 substantially parallel to the first sheet 131 and located on the same plane, and a third sheet 133 vertically connected to the end edges of the first sheet 131 and the two second sheets 132 on the same side.

Furthermore, a fastening block 1312 is punched from the first sheet 131 at the approximate center toward the second sheet 132, and two guiding slots 1315 are respectively formed at two sides of the fastening block 1312. The first sheet 131 is connected to the third sheet 133 at substantially the center thereof, and two notches 1313 are formed in a recessed manner in the direction of the top engagement portion 1311. The aperture of the notch 1313 is slightly larger than the width of the stop 1113 perpendicular to the fastening direction S2.

The two second panels 132 are formed by extending from the third panel 133 along the fastening direction S2 on two opposite sides (e.g. the left lower side and the right upper side in fig. 2) of the end edge far from the first panel 131. The distance between each second sheet 132 and the first sheet 131 is substantially equal to the height difference between the top surface of each side arm 112 and the top surface of the base 111. Furthermore, each second sheet 132 can be divided into a wide section 1321 and a narrow section 1323 according to the width.

For one of the second plate members 132, the wide edge portion 1321 is formed by extending from the third plate member 133, and an inner portion of the wide edge portion 1321 away from the third plate member 133 is defined as an inner fastening portion 1322; the wide edge 1321 is located near the inner engaging portion 1322 and extends to form the narrow edge 1323, and the end of the narrow edge 1323 away from the third plate 133 is defined as an end engaging portion 1324.

Wherein, the pressing member 14 includes: a substrate 141, a pressing portion 142, a fastening portion 143, an embedding portion 144 and a welding portion 145, wherein the upper edge of the substrate 141 is bent toward the insulating base 11 to form the pressing portion 142, the fastening portion 143 is cut at the position of the adjacent pressing portion 142 of the substrate 141, the fastening portion 143 is fixed in a fastening block 1115 protruding outward from two sidewalls of the insulating base 11, the front end of the substrate 141 is reversely folded to form the embedding portion 144, the embedding portion 144 is embedded in the embedding groove 1123 of the sidewall, and the lower edge of the substrate 141 is bent outward to form the welding portion 145 to be fixed on a circuit substrate (not shown in the drawing).

As shown in fig. 3 and 4, when the fastening member 13 is inserted into the insulating base 11 and located at the first position, the stopper 1113 is received in the notch 1313 and abuts against the edge of the notch 1313 away from the third plate 133, and the fastening block 1312 and the third plate 133 are located on the base 111 away from the alignment block 113. Furthermore, the top engaging portion 1311 of the first plate 131 is disposed (e.g., abutted) on the top surface of the base 111, the two second plates 132 are respectively inserted into the through slots 1121 of the two side arms 112, and each inner engaging portion 1322 and each end engaging portion 1324 are disposed in the through slot 1121.

Referring to fig. 3, 4 and 5, when the fastening member 13 is adjusted to the second position along the fastening direction, the third plate 133 moves toward the limiting block 1113, the edge of the guiding groove 1315 of the first plate 131 abuts against and slides on the inner edge of the guiding strip 1111, and the fastening block 1312 straddles the fastening portion 1114 of the insulating base 11. Furthermore, the top fastening portion 1311 of the first plate 131 passes through the opening 1112 and hangs outside the insulating body 21 (i.e., above the plate 114), and the inner fastening portion 1322 and the end fastening portion 1324 of each second plate 132 pass through the through slot 1121 and hang outside the insulating base 11. Each inner engaging portion 1322 corresponds to the notch 1122 of each side arm 112, and is located away from the side wall of the base 111 of the insulating base 11 at the second position.

In summary, the top fastening portion 1311, the inner fastening portion 1322, and the end fastening portion 1324 of the fastener 13 can be collectively defined as a first fastening unit. That is, when the fastener 13 is located at the second position, the first fastening unit of the fastener 13 is suspended outside the insulating base 11.

Referring to fig. 1 and 6, the terminal connector 2 includes an insulating body 21, a plurality of butt terminals 22, and a plurality of cables 23. The butt-joint terminal 22 is inserted into (the base 211 of) the insulating body 21 and the positions thereof respectively correspond to the positions of the conductive terminals 12, and the cables 23 are respectively connected and fixed to the butt-joint terminal 22.

The insulating body 21 is a symmetrical structure formed integrally, and the outer shape thereof corresponds to the insulating base 11. The insulating body 21 has a long columnar base 211, two inner locking blocks 212 formed by protruding from two opposite sides of the base 211, two alignment rings 213, and two end locking blocks 214.

A top engaging groove 2111 is concavely formed in the top surface of the base 211 at the approximate center of the front end, and the contour of the top engaging groove 2111 approximately corresponds to the top engaging portion 1311. The position and shape of each inner snap-fit block 212 substantially corresponds to each gap 1122. Each alignment ring 213 is U-shaped and has two opposite ends connected to the side of the base 211, such that each alignment ring 213 and the base 211 surround and define an alignment hole 2131 corresponding to the alignment block 113.

Furthermore, each end fastening block 214 is connected to the bottom surface of the rear end of each alignment ring 213, and the top surface of each end fastening block 214 and the alignment ring 213 connected thereto surround to form an end fastening groove 2141 communicating with the alignment hole 2131. It should be noted that the top locking groove 2111, the inner locking block 212, and the end locking block 214 of the insulating main body 21 can be collectively defined as a second locking unit.

Therefore, as shown in fig. 4, 7 and 8, when the fastener 13 of the board-end connector 1 is located at the first position, the wire-end connector 2 can be detachably mounted on the board-end connector 1 along the inserting and pulling direction S1, so that the insulating body 21 is embedded in the insulating base 11, and the pair of terminals 22 respectively abut against the conductive terminals 12. More specifically, the front end of the base 211 of the terminal connector 2 is received in the space surrounded by the base 111, the side arms 112, and the plate 114 of the terminal connector 1, each inner locking block 212 is engaged with the notch 1122 of each side arm 112, each alignment hole 2131 is sleeved on each alignment block 113, and the two end engaging grooves 2141 are respectively located on the extending paths of the two through grooves 1121.

Then, after the wire end connector 2 is installed on the board end connector 1, the fastener 13 is adapted to be adjusted from the first position to the second position (as shown in fig. 5, 9, and 10), so that the first engaging unit of the fastener 13 is disposed on the second engaging unit of the insulating body 21, and the second engaging unit of the wire end connector 2 is blocked by the first engaging unit of the fastener 13 in the inserting and pulling direction S1 and cannot move relative to the board end connector 1.

More specifically, when the terminal connector 2 is mounted on the board connector 1 and the fastener 13 is adjusted to the second position, a fastening block 1312 of the fastener 13 spans over the fastening portion 1114 of the insulative base 11, so that the fastener 13 can be stably positioned at the second position.

At this time, the top locking portion 1311 of the fastener 13 penetrates through the opening 1112 and is received in the top locking slot 2111 of the insulating housing 21 (that is, the base 211 of the insulating housing 21 is clamped between the board body 114 of the insulating base 11 and the top locking portion 1311); the inner engaging portion 1322 of each second plate 132 extends through the through slot 1121 and is located substantially above the notch 1122 of each side arm 112, so as to be disposed on the top surface of each inner engaging block 212 (i.e., the inner engaging block 212 is located between the plate body 114 and the outer surface of the inner engaging portion 1322 away from the first plate 131).

Furthermore, the end fastening portion 1324 of each second sheet 132 penetrates through the through groove 1121 and extends into each end fastening groove 2141 so as to be disposed on the top surface of each end fastening block 214 (that is, the end fastening block 214 is equivalent to be abutted against the outer surface of the end fastening portion 1324 away from the first sheet 131), and two sides of the insulating base 11 are respectively provided with a pressing member 14, the pressing member 14 extends toward the fastening member 13 to form a pressing portion 142, wherein the pressing portion 142 presses against two side edges of the long side of the fastening member 13, so as to prevent the fastening member from being separated from the insulating base 11 in the plugging direction S1.

In summary, the connector assembly according to the embodiment of the present application can be provided with the fastening member through the board-side connector, so that the first fastening unit is matched with the second fastening unit by moving the fastening member along the fastening direction, and the second fastening unit of the cable-side connector is restricted by the first fastening unit in the plugging direction and is not movable. Thereby, the plate end connector and the wire end connector can be firmly jointed with each other.

Furthermore, the board end connector provided by the embodiment of the present application further forms a buckling portion and a buckling block, a limiting block and an incision which are matched with each other on the insulating base and the buckling member. Therefore, the buckling piece can be stably adjusted between the first position and the second position relative to the insulating base body.
