[0078] The following is a description of an easy-lock connector for flat connection of objects according to an embodiment of the present invention with reference to the accompanying drawings. In each of the drawings, the same elements are marked with the same reference numerals. The drawings are not drawn to scale.

[0079] Figure 1 It is a stereoscopic view of an easy-lock connector for flat connection objects according to an embodiment of the utility model. Figure 2 1 is a perspective exploded view of an easy-lock connector for flat connection objects according to an embodiment of the present invention. The easy-lock connector for flat connection objects is generally indicated by reference numeral 10. Figure 1 and Figure 3 , the components of the easy-lock connector 10 of the embodiment of the utility model are briefly described. The easy-lock connector 10 includes an insulating housing 11, an operating member 12, a pair of metal fittings 13 and a plurality of contact members 14.

[0080] Figure 2 The diagram shows that the flat connection object 20 is inserted into the easy-lock connector 10 along the first direction D1 (ie, the mating direction). The flat connection object 20 may be a flexible flat cable (FFC) or a flexible printed circuit (FPC), but is not limited thereto.

[0081] The insulating housing 11 is made of insulating synthetic resin or polymer material. The insulating housing 11 is formed with a fitting opening 110 for inserting a flat connection object. The flat connection object can be inserted into the easy-lock connector 10 along a first direction D1.

[0082] The two metal fittings 13 are respectively fixed to the two ends of the insulating housing 11 in the second direction D2 (width direction), and the second direction D2 is perpendicular to the first direction D1. The metal fittings 13 are made of metal or alloy material. The metal fittings 13 are a single-piece component manufactured by stamping and bending a metal sheet. The plurality of contacts 14 are arranged along the second direction D2 and are held by the insulating housing 11. Each contact 14 is made of copper or a copper alloy.

[0083] The operating member 12 is configured to be pivotable between an unlocked position and a locked position relative to the insulating housing 11. On the one hand, the operating member 12 is used to lock the flat connection object 20 inserted into the easy-lock connector 10, preventing the inserted flat connection object 20 from being separated from the easy-lock connector 10. On the other hand, the operating member 12 is operated to unlock the flat connection object 20, allowing the flat connection object 20 to be removed from the easy-lock connector 10.

[0084] The specific structures of the operating member 12 and the metal fitting 13 will be described below.

[0085] Figure 4 FIG. 1 is another perspective view of the easy-lock connector 10 for flat connection objects according to an embodiment of the present invention, wherein the operating member 12 is not shown. Figure 4 As shown, the insulating housing 11 has a pivot receiving portion 111, which is configured to rotatably support a pivot portion 121 (shown in FIG. Figure 5 The pivot receiving portion 111 is formed above the fitting opening 110 .

[0086] Figure 5 It is a stereoscopic view of an operating member 12 of an easy-lock connector for connecting flat connection objects according to an embodiment of the utility model. Figure 6 1 is a perspective view of the core 120 of the operating member 12. Figure 5 and 6 , the structure of the operating member 12 is further described. In this embodiment, the operating member 12 includes a metal core 120 and a resin outer covering that covers at least a portion of the core 120. The operating member 12 is formed by insert injection molding using the metal core 120 as an insert. Figure 5 As shown, the operating member 12 has a pivot portion 121 parallel to the second direction D2. The pivot portion 121 is composed of a resin outer covering. The pivot portion 121 is constructed in a substantially cylindrical shape. The pivot portion 121 is received in the pivot receiving portion 111 of the insulating housing 11 and is rotatably supported by the pivot receiving portion 111, so that the operating member 12 can rotate around the pivot portion 121 between an unlocked position and a locked position. The operating member 12 includes a pair of latch portions 122 formed at both ends respectively. The latch portion 122 is composed of a portion of the core 120 exposed outside the outer covering. The latch portion 122 is in a direction perpendicular to the second direction (i.e. Figure 5 The third direction D3) extends so that when the operating member 12 is in the locked position, the pair of latch portions 122 will extend into the recess of the flat connection object and interfere with the recess to lock the flat connection object.

[0087] The operating member 12 has an operating portion 124 facing upward. The operating portion 124 is also formed of a resin outer cover. When a user applies a pressing force to the operating portion 124, the operating member 12 is rotated from the locking position to the unlocking position around the pivot portion 121. In the unlocking position, the pair of latch portions 122 will not interfere with the notch of the flat connection object, and will not hinder the flat connection object from being withdrawn from the easy-lock connector.

[0088] The latch portion 122 is configured not to hinder the insertion of the flat connection object. Specifically, the front edge of the latch portion 122 is inclined toward the insertion direction of the flat connection object. During the process of inserting the flat connection object into the fitting opening 110 of the insulating housing 11, the insertion end of the flat connection object will abut the front edge of the latch portion 122, and further movement of the flat connection object in the insertion direction will cause the latch portion 122 to swing backward, so that the operating member 12 is biased from the locking position to the unlocking position. Therefore, the latch portion 122 will not hinder the insertion of the flat connection object. The locking of the flat connection object can be achieved only by inserting the flat connection object into the fitting opening 110 of the insulating housing 11, without the need to additionally operate other components. This is very beneficial for the automated assembly of the flat connection object and the easy-lock connector.

[0089] The difference from the conventional technology is that the operating member 12 of the easy-lock connector of the present invention further includes a pair of columnar buckle parts 125 extending in the first direction D1. The columnar buckle parts 125 are also composed of a resin outer cover. The structure and function of the columnar buckle parts 125 will be described in detail below.

[0090] like Figure 6 As shown, the metal core 120 includes a main body 1200. Latch parts 122 are formed at both ends of the main body 1200. The main body 1200 is formed with a plurality of elongated slots 1201. When the outer covering is formed by insert injection molding, the flowing resin flows through the elongated slots 1201 and fills the elongated slots 1201. In this way, the bonding strength between the resin outer covering and the metal core can be increased. The metal core 120 can also act as a reinforcing member of the operating member 12, which can suppress the deformation or warping of the operating member 12 caused by external force or contraction of the resin part.

[0091] Although in this embodiment, the operating member 12 is formed by insert injection molding with the core 120 as an insert, the present invention is not limited thereto. The operating member can also be a single component made of resin by injection molding.

[0092] Figure 71 is a schematic diagram showing that the flat connection object 20 has been inserted into the easy-lock connector. The flat connection object 20 includes a pair of notches 201 and a plurality of electrode portions (not shown) formed at the insertion end of the flat connection object. The pair of notches 201 are respectively formed at two opposite side edges of the flat connection object and adjacent to the insertion end. In order to clearly show the relationship between the flat connection object 20 and the operating member 12, the insulating housing and the metal fittings are not shown. Figure 7 .exist Figure 7 In the embodiment, the operating member 12 is in a locked position, in which the latch portion 122 extends into the notch 201 of the flat connection object 20 and engages with the notch 201 of the flat connection object 20 to prevent the flat connection object from being detached from the easy-lock connector or being pulled out of the easy-lock connector.

[0093] Figure 8 1 is a schematic diagram showing that the operating member 12 is biased by the first elastic arm 131 of the metal fitting 13. In order to clearly show the relationship between the operating member 12 and the metal fitting 13, the insulating housing and the contact member are not shown. Figure 8 .like Figure 8 As shown, the first elastic arm 131 of the metal accessory 13 extends to the bottom of the operating portion 124 of the operating member 12 and presses against the operating portion 124 from the bottom. The first elastic arm 131 is used to constantly apply an upward biasing force to the operating member 12, so that the operating member 12 is constantly biased toward the locked position. For example, when a user applies a pressing force to the operating portion 124 of the operating member 12 to rotate the operating member 12 to the unlocked position, the first elastic arm 131 will apply a biasing force on the operating portion 124 in the opposite direction of the pressing force. Once the user no longer applies the pressing force, the biasing force applied by the first elastic arm 131 will force the operating member 12 to return from the unlocked position to the locked position.

[0094] Reference Figures 9 to 12 The structure and function of the columnar buckle portion 125 are described. Fig. 9 is a front view of the easy-lock connector 10 according to an embodiment of the utility model when viewed from a first direction D1. Fig.10 is along Fig. 9 The cross-section taken along the midline AA, Fig.11 is along Fig. 9 The cross-section taken along the midline BB, Fig.12 is along Fig. 9 The cross-section is taken along the center line CC. Fig.10 As shown, the pivot portion 121 of the operating member 12 and the pivot receiving portion of the insulating housing 11 are configured such that the pivot portion 121 is rotatably supported by the pivot receiving portion of the insulating housing 11. When the user applies a pressing force to the operating portion 124, Fig.10 The operating member 12 shown will rotate in a counterclockwise direction around the pivot portion 121. Fig.11As shown, the columnar buckle portion 125 extending in the first direction D1 toward the rear of the easy-lock connector 10 is blocked by the insulating housing 11 on one surface (i.e., the lower surface) in the third direction. Fig.11 In the state shown, because the lower surface of the columnar buckle portion 125 abuts against the insulating housing 11, the operating member 12 cannot rotate in the clockwise direction around the pivot portion 121. At this time, the columnar buckle portion 125 acts to prevent the operating member 12 from rotating from the locked position to the direction away from the unlocked position (i.e. Fig.11 Therefore, even if the flat connection object is forcibly pulled outward from the easy-lock connector without unlocking, the operating member 12 is still firmly held in the locked position, preventing the flat connection object from being separated from the easy-lock connector due to misoperation.

[0095] like Fig.12 As shown, the columnar buckle portion 125 is formed with a hook portion 1251 at the end. The hook portion 1251 is engaged with the protrusion 112 formed inside the insulating housing 11. The engagement between the hook portion 1251 and the protrusion 112 prevents the operating member 12 from moving outward in the first direction D1. At this time, the columnar buckle portion 125 acts as a means to prevent the operating member 12 from moving outward in the first direction D1. Therefore, it can prevent the operating member 12 from being separated from the easy-lock connector due to misoperation.

[0096] Reference Fig.13 and Fig.14 The structure of the metal fitting 13 is described. Fig.13 is a perspective view of the metal fitting 13, and Fig.14 1 is another three-dimensional view of the metal fitting 13. The first elastic arm 131 of the metal fitting 13 extends from the main body 130 of the metal fitting 13 approximately in the second direction D2, and is used to constantly bias the operating member 12 toward the locking position. The metal fitting 13 also has a second elastic arm 132 disposed below the first elastic arm 131. The second elastic arm 132 extends into the fitting opening 110, and is used to tightly press the inserted flat connection object upward in the third direction D3 in the fitting opening 110. This helps to keep the flat connection object in a position where it can interfere with the latch portion 122 of the operating member 12.

[0097] The metal fitting 13 also includes a U-shaped bent portion 134 extending from the main body 130. The U-shaped bent portion 134 has a stopper 1341 at the end. The stopper 1341 is positioned in front of the front edge of the latch portion 122 of the operating member 12 in the first direction D1, and is used to prevent the operating member 12 from moving outward in the first direction D1 and prevent the operating member 12 from moving from the locked position to the direction away from the unlocked position (i.e., Fig.11 clockwise in the direction of rotation).

[0098] In order to fix the metal fitting 13 to the insulating housing 11, the metal fitting 13 also includes a first retaining portion 133 extending from the main body 130 and a second retaining portion 1342 extending from the U-shaped bent portion 134. The first retaining portion 133 and the second retaining portion 1342 extend in the first direction D1 toward the rear of the easy-lock connector. The metal fitting 13 further includes a third retaining portion 136 disposed on a different plane from the first retaining portion 133 and the second retaining portion 1342. The third retaining portion 136 extends in the first direction D1 toward the rear of the easy-lock connector. The first retaining portion 133, the second retaining portion 1342 and the third retaining portion 136 each have a barb structure and are inserted into a retaining groove or a retaining hole formed in the insulating housing in an interference fit manner.

[0099] The metal fitting 13 further includes a first solder leg 135 extending from the first holding portion 133 and a second solder leg 137 extending from the third holding portion 136. The first solder leg 135 and the second solder leg 137 are positioned in a plane perpendicular to the first direction D1. The first solder leg 135 and the second solder leg 137 can be soldered to a solder pad of a circuit board (not shown) using surface mounting technology (SMT), thereby fixing the easy-lock connector to the circuit board.

[0100] Reference Fig.15 The structure of the contact element 14 is described, wherein Fig.15 1 is a perspective view showing the contact member 14 .

[0101] like Fig.15 As shown, the contact member 14 has a connection terminal portion 141, a holding portion 142, a contact arm 143 and a contact portion 144. The contact arm 143 extends from one end of the holding portion 142, and the connection terminal portion 141 extends from the other end of the holding portion 142. The holding portion 142 is formed with a barb structure. The holding portion 142 is inserted into a corresponding holding groove or holding hole formed in the insulating housing 11 in an interference fit manner. The contact portion 144 is formed at the distal end of the contact arm 143. The contact arm 143 extends toward the mating opening of the insulating housing 11 so that the contact portion 144 can contact the electrode portion formed on the flat object. The connection terminal portion 141 extends from the insulating housing 11 and extends in a third direction D3. The connection terminal portion 141 can be soldered to a solder pad formed on a circuit board (not shown) by surface mounting technology (SMT).

[0102] Although the present invention is described with reference to the preferred embodiments, it should be understood that within the spirit and scope of the present invention, many changes and modifications are possible for those with ordinary technical knowledge in the technical field to which the present invention belongs.
