[0022] According to the easy-lock connector of the present invention, the front edge of each latch portion is configured to be inclined toward the insertion direction of the flat connection object, so that when the flat connection object is inserted into the easy-lock connector, the flat connection object will push against the front edge of each latch portion, causing the pair of latch portions to be biased to the unlocked position.

[0023] According to the easy-lock connector of the present invention, the insulating housing has a pivot receiving portion, and the pivot receiving portion is configured to rotatably support the pivot portion of the operating member.

[0024] According to the easy-lock connector of the present invention, a stop portion is formed on the front edge of each latch portion, and the stop portion prevents the abutting portion from moving in the second direction or preventing the abutting portion from being biased toward the second direction.

[0025] According to the easy-lock connector of the present invention, latch portions are formed at both ends of the operating member.

[0075] The following describes an easy-lock connector for flat connection 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.

[0076] Reference Figure 1 and Figure 2 , briefly describes the components of the easy-lock connector 10 of the embodiment of the present utility model, wherein Figure 1 This is a perspective view of an easy-lock connector for flat connection objects according to an embodiment of the utility model. Figure 2 This is an exploded perspective view of an easy-lock connector for connecting flat objects according to an embodiment of the present invention. The easy-lock connector for connecting flat objects is generally designated by reference numeral 10. The easy-lock connector 10 includes an insulating housing 11, an operating member 12, a pair of metal fittings 13, and a plurality of contacts 14.

[0077] Figure 3 The diagram shows a flat connection object 20 being inserted into the easy-lock connector 10 along a first direction D1 (ie, a 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.

[0078] The insulating housing 11 is made of an 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.

[0079] Two metal fittings 13 are fixed to the insulating housing 11 at either end in the second direction D2 (widthwise), which is perpendicular to the first direction D1. The metal fittings 13 are made of metal or an alloy. The metal fitting 13 is a single-piece component manufactured by stamping and bending a metal sheet. The multiple contacts 14 are arranged along the second direction D2 and held by the insulating housing 11. Each contact 14 is made of copper or a copper alloy.

[0080] The operating member 12 is made of an insulating synthetic resin or polymer material. The operating member 12 is configured to pivot relative to the insulating housing 11 about a pivot portion between an unlocked position and a locked position. The operating member 12 locks the flat connection object 20 inserted into the easy-lock connector 10, preventing it from being removed from the easy-lock connector 10. Furthermore, operating the operating member 12 unlocks the flat connection object 20, allowing it to be removed from the easy-lock connector 10.

[0081] The specific structure of the operating member 12 and the metal fitting 13 will be described below.

[0082] 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 the pivot portion 121 (shown in FIG. Figure 5 The pivot receiving portion 111 is formed above the fitting opening 110 .

[0083] Figure 5 1 is a perspective view of an operating member 12 of an easy-lock connector for connecting flat connection objects according to an embodiment of the present invention. Figure 5 , further illustrating the composition of the operating member 12. In this embodiment, as Figure 5 As shown, the operating member 12 has a pivot portion 121 parallel to the second direction D2. The pivot portion 121 is configured to be substantially cylindrical. 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 the unlocked position and the locked position. The operating member 12 includes a pair of latch portions 122 formed at both ends. The latch portion 122 is perpendicular to the second direction (i.e., Figure 5 The third direction D3 in FIG. 1 extends so that when the operating member 12 is in the locked position, the pair of latch portions 122 extend into the recess of the flat connection object (shown in FIG. Figure 6 ) and interfere with the notch to lock the flat connection object.

[0084] The operating member 12 has an upward-facing operating portion 124. When a user applies pressure to the operating portion 124, the operating member 12 rotates about the pivot portion 121 from a locked position to an unlocked position. In the unlocked position, the pair of latches 122 do not interfere with the recesses of the flat object being connected, preventing the object from being removed from the easy-lock connector. This allows the user to smoothly remove the flat object from the easy-lock connector.

[0085] The latch portion 122 is constructed so as 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. Further movement of the flat connection object in the insertion direction will cause the latch portion 122 to swing around the pivot portion 121 in the insertion direction of the flat connection object, so that the operating member 12 is biased from the locked position to the unlocked position. Therefore, the latch portion 122 will not hinder the insertion of the flat connection object. The flat connection object can be locked simply by inserting the flat connection object into the fitting opening 110 of the insulating housing 11, without the need to operate other components. This is very beneficial for the automated assembly of the flat connection object and the easy-lock connector.

[0086] 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 pawl portions 125. The pawl portions 125 are formed near the latch portion 122. The structure and function of the pawl portions 125 will be described in detail below.

[0087] Figure 6 This is a schematic diagram showing a flat connection object 20 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 formed on two opposite side edges of the flat connection object and adjacent to the insertion end. In order to clearly illustrate the relationship between the flat connection object 20 and the operating member 12, the insulating housing and metal fittings are not shown. Figure 6 .exist Figure 6 In the locking position, the operating member 12 is in the locking position. In the locking position, the latch portion 122 extends into the recess 201 of the flat connection object 20 and engages with the recess 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.

[0088] Figure 7 1 is a schematic diagram showing that the operating member 12 is biased by the 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 7 .like Figure 7As shown, the elastic arm 131 of the metal fitting 13 substantially extends in a first direction to below the operating portion 124 of the operating member 12 and abuts against the operating portion 124 from below. The elastic arm 131 constantly applies an upward biasing force to the operating member 12, thereby constantly biasing the operating member 12 toward the locked position. For example, when a user applies a pressing force to the operating portion 124 of the operating member 12, causing the operating member 12 to rotate to the unlocked position, the elastic arm 131 applies a biasing force to the operating portion 124 in the opposite direction of the pressing force. Once the user ceases applying the pressing force, the biasing force exerted by the elastic arm 131 forces the operating member 12 back from the unlocked position to the locked position.

[0089] Visible in Figure 7 The latch portion 122 is formed with a stopper 1221 at the upper portion of the front edge. The abutment 1321 of the metal fitting 13 abuts against the front edge of the latch portion 122, preventing the latch portion 122 from swinging forward. On the other hand, the stopper 1221 prevents the abutment 1321 from shifting or deforming laterally. Due to the stopper 1221, even if the abutment 1321 is pushed forward by the front edge of the latch portion 122, the abutment 1321 is not easily shifted or deformed laterally, thereby ensuring resistance to the tendency of the latch portion 122 to pivot outward. Therefore, it is possible to prevent the user from pulling out the flat connector from the easy-lock connector without operating the operating member or releasing the lock on the flat connector.

[0090] Reference Figures 8 to 10 The structure and function of the latch portion 125 are described. Figure 8 This is a front view of the easy-lock connector 10 according to an embodiment of the present invention when viewed from a first direction D1. Figure 9 It is along Figure 8 The cross-section taken along the midline AA, Figure 10 It is along Figure 8 The cross-section taken along the center line BB. Figure 9 As shown, the pivot portion 121 of the operating member 12 and the pivot receiving portion of the insulating housing 11 are configured so 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, Figure 9 In the present embodiment, the operating member 12 rotates counterclockwise around the pivot portion 121 .

[0091] In the first direction, the latch portion 125 is substantially formed behind the pivot portion 121. The latch portion 125 has a first surface 1251 and a second surface 1252. The first surface 1251 is parallel to the first direction D1 and the second direction D2. That is, the normal line of the first surface 1251 is parallel to the third direction D3. Figure 10As shown, the angle between the first surface 1251 and the second surface 1252 is less than 90 degrees. The insulating shell 11 is formed with a stepped portion that engages with the pawl portion 125, and the stepped portion is composed of a third surface 1111 and a fourth surface 1112, wherein the third surface 1111 is parallel to the first surface 1251, and the fourth surface 1112 is parallel to the second surface 1252. When a force acting in the direction of pulling out the flat connection object is applied to the operating member 12, the second surface 1252 of the pawl portion 125 will abut against the fourth surface 1112, so that a reaction force is applied to the second surface 1252 of the pawl portion 125. Because the angle between the first surface 1251 and the second surface 1252 is set to be less than 90 degrees, the aforementioned reaction force includes a component force acting downward in the third direction D3. The component force acting downward in the third direction D3 helps to prevent the operating member 12 from detaching from the insulating shell 11. Therefore, the operating member 12 can be prevented from detaching from the easy-lock connector due to misoperation. Figure 10 In the illustrated state, because the second surface 1252 of the pawl portion 125 abuts against the fourth surface 1112 and the first surface 1251 of the pawl portion 125 abuts against the third surface 1111, the operating member 12 cannot rotate clockwise about the pivot portion 121. Therefore, even if the flat connection object is forcibly pulled outward from the easy-lock connector without being unlocked, 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 accidental operation.

[0092] Reference Figure 11 and Figure 12 The structure of the metal fitting 13 is described. Figure 11 is a perspective view of the metal fitting 13, and Figure 12 This is another perspective view of the metal fitting 13. The metal fitting 13 includes a main body 130, a resilient arm 131, a U-shaped bend 132, a retaining portion 133, a first weld 134, and a second weld 135. The resilient arm 131 is connected near the rear end of the main body 130 and extends substantially in the first direction D1 to below the operating portion 124 of the operating member 12, thereby constantly biasing the operating member 12 toward the locked position. The U-shaped bend 132 extends from the front end of the main body 130 in the direction of removal of the flat connector and then bends back toward the direction of insertion. The U-shaped bend 132 has a contact portion 1321 at its distal end.

[0093] The abutting portion 1321 is positioned in front of the front edge of the latch portion 122 of the operating member 12 in the first direction D1 (eg, Figure 7 ), for preventing the operating member 12 from moving outward in the first direction D1 and preventing the operating member 12 from moving from the locked position to the direction away from the unlocked position (ie Figure 9 (clockwise in the direction of rotation).

[0094] The main body 130 and the U-shaped bend 132 of the metal fitting 13 are respectively formed with a first detent portion 1301 and a second detent portion 1322, which are used to secure the main body 130 and the U-shaped bend 132 of the metal fitting 13 to the insulating housing 11. The first detent portion 1301 and the second detent portion 1322 are formed by punching, tearing and bending portions of the main body 130 and the U-shaped bend 132 relative to the other portions.

[0095] The retaining portion 133 is connected to the lower edge of the main body 130 and extends in the first direction D1. The retaining portion 133 has a barbed structure. The retaining portion 133 is inserted into a corresponding retaining groove or retaining hole formed in the insulating housing 11 in an interference fit, thereby securing the metal fitting 13 to the insulating housing 11.

[0096] The first soldering portion 134 is connected to the main body 130, and the second soldering portion 135 is connected to the retaining portion 133. The first soldering portion 134 and the second soldering portion 135 are positioned in a plane perpendicular to the first direction D1. Surface mount technology (SMT) can be used to solder the first soldering portion 134 and the second soldering portion 135 to pads on a circuit board (not shown), thereby securing the easy-lock connector to the circuit board.

[0097] Reference Figure 13 The structure of the contact element 14 is described, wherein Figure 13 A perspective view of the contact 14 is shown.

[0098] like Figure 13 As shown, the contact 14 has a connection terminal portion 141, a retaining portion 142, a contact arm 143 and a contact portion 144. The contact arm 143 extends from one end of the retaining portion 142, and the connection terminal portion 141 extends from the other end of the retaining portion 142. The retaining portion 142 is formed with a barb structure. The retaining portion 142 is inserted into a corresponding retaining groove or retaining 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 fitting opening 110 of the insulating housing 11 so that when the flat connection object 20 is inserted into the easy-lock connector 10, the contact portion 144 of the contact 14 can contact the electrode portion formed on the flat connection object. The connection terminal portion 141 extends from the insulating housing 11 and extends approximately in the third direction D3. The connection terminal portion 141 can be soldered to a solder pad formed on a circuit board (not shown) by surface mount technology (SMT).

[0099] Although the present invention is described with reference to preferred embodiments, it should be understood that many variations and modifications are possible within the spirit and scope of the present invention for those skilled in the art. Therefore, the present invention is not limited to the embodiments described, but is subject to the text of the claims. In other words, equivalent variations and modifications that do not depart from the scope of the present invention are still within the scope of the present invention.
