In another embodiment, the easy-lock connector can also achieve the effect of electromagnetic shielding by adding an external shielding iron shell.

Description

[Technical field]

[0001] The invention relates to the technical field of a connector, in particular to an easy-lock connector with a press-to-unlock structure which can automatically latch a flat wire. [Background technology]

[0002] Traditional connectors are intermediate connection components for connecting wires to circuit boards. The advantage is that they do not need to be physically soldered to the circuit board, so that users can easily achieve electrical connection by plugging and unplugging. In order to ensure that the connector and the wire can have a stable contact, a variety of connection methods have been developed, such as the automatic latching method, which allows the automatic latching connector and the wire to be easily connected without falling off.

[0003] As the miniaturization of connectors accompanies the high frequency problem and the difficulty of operation, the present invention proposes an easy-lock connector with a push-to-unlock structure, which is used to solve the defects caused by the traditional automatic lock connector. [Summary of the invention]

[0004] The first object of the present invention is to provide an easy-lock connector with a push-to-unlock structure, comprising an upper shell, a lower shell, a rubber core and a terminal. The multi-component structure not only has the functions of automatic latching and push-to-unlock, but also can resist noise and smoothly transmit signals in a high-frequency environment.

[0005] The second objective of the present invention is to achieve the purpose of unlocking by indirectly driving the lower shell through the upper shell according to the aforementioned easy-lock connector with a push-to-unlock structure.

[0006] The third purpose of the present invention is to form an inclined surface on the rubber core to limit the deformation amount generated by the pressing part of the upper shell acting on the elastic part of the lower shell according to the aforementioned easy-lock connector with a push-to-unlock structure, so as to avoid excessive pressing to damage the elastic part and the pressing part, thereby achieving the purpose of prolonging the service life.

[0007] The fourth object of the present invention is that according to the aforementioned easy-lock connector with a push-to-unlock structure, the elastic part of the lower shell is shaped like a U-shaped body with a large R angle, which can not only provide interference with the pressing part of the upper shell, but also allow the operation to have a feedback feel.

[0008] The fifth object of the present invention is that according to the aforementioned easy-lock connector with a push-to-unlock structure, the lower shell provides a lower shell grounding piece formed in the second accommodating space for contacting the grounding wire of the flat wire, so as to achieve the effect of improving high-frequency crosstalk.

[0009] A sixth objective of the present invention is that according to the aforementioned easy-lock connector with a push-to-unlock structure, the upper shell has a shielding effect to improve the problems of electromagnetic compatibility (EMC) and electromagnetic interference (EMI).

[0010] The seventh objective of the present invention is to provide a shielding iron shell covering the connector based on the aforementioned easy-lock connector with a push-to-unlock structure to improve EMI and EMC problems.

[0011] The eighth purpose of the present invention is to provide a floating structure to improve the welding yield of the connector and the circuit board by setting plug-in, buckle and snap-fit ​​structures on the shielding iron shell, the rubber core and the upper shell according to the aforementioned easy-lock connector with a push-to-unlock structure.

[0012] To achieve the above-mentioned and other purposes, the present invention provides an easy-lock connector with a press-unlock structure, which is applied to a flat wire and a circuit board. The flat wire has a notch and a grounding wire on the two sides of its head end respectively. The easy-lock connector with a press-unlock structure includes an upper shell, a lower shell, a rubber core and a terminal. The upper shell can be arranged on the circuit board. The upper shell forms a first accommodating space, which has an upper body and a pressing member. The pressing member is formed on the two sides of the upper body through a break. The pressing member also includes a first fixing member. The first fixing member is formed on the two sides of the upper body and the first fixing member can be fixed on the circuit board. The lower shell is arranged in the first accommodating space. The lower shell forms a second accommodating space, which has an elastic member, a stopper, an extension arm and a lower body. The elastic members are respectively arranged on the two sides of the lower body and are arranged corresponding to the position of the pressing member. The stopper is arranged with a snap-on notch according to the notch, and the stopper is connected to the elastic member through the extension arm. The rubber core is arranged in the second accommodating space. The rubber core is formed with an insertion port, an action portion and an opening portion. The insertion port allows the flat wire to be inserted and withdrawn. The action portion is combined with the elastic member and the opening portion for setting the elastic member. The terminal is set on the rubber core to be able to electrically connect the flat wire. After the notch of the flat wire is buckled by the stopper, the pressing member is pressed so that the pressing member applies an external force to the elastic member to deform the elastic member, and the elastic member links the extension arm to make the stopper move in one direction to release the state of the notch of the stopper buckling.

[0013] Compared to the prior art, the easy-lock connector with a push-to-unlock structure provided by the present invention is applied to flat wires, so that the flat wires can be automatically locked in the accommodation space of the easy-lock connector through the multi-piece easy-lock connector, and by applying external force to the pressing piece of the easy-lock connector, the elastic piece located in the lower shell can be directly driven to unlock. In one embodiment, during the unlocking process, the pressing piece is limited by the inclined surface of the rubber core so as not to damage the elastic piece or other components. Furthermore, the easy-lock connector of the present invention provides a variety of electromagnetic shielding or electromagnetic shielding structures, which can effectively prevent external noise from affecting signal transmission or high-frequency signals from affecting signal transmission of other external components.

[0070] Please refer to Figure 1, is a schematic structural diagram of an easy-lock connector with a push-to-unlock structure according to a first embodiment of the present invention. Figure 1 In the embodiment, an easy-lock connector 10 (hereinafter referred to as an easy-lock connector) with a push-to-unlock structure is applied to a flat wire 2 (see Figure 2 ) and a circuit board 4 having a ground terminal 42 (see Fig.12 Schematic diagram of Figure 2 In the figure, the flat wire 2 has a notch 22 and a grounding wire (not shown, formed on the upper and lower surfaces of the flat wire 2) on the two sides of its head end. Figure 2 It is also shown that the terminal 18 mentioned below is disposed on the plastic core 16 to be able to electrically connect the flat wire 2 .

[0071] Back to Figure 1 The easy-lock connector 10 includes an upper housing 12 , a lower housing 14 , a rubber core 16 and terminals 18 .

[0072] For reference Figure 3 , is to illustrate the present invention Figure 1 Schematic diagram of the shell structure. Figure 3 In the embodiment, the upper housing 12 can be disposed (for example, by welding, surface mounting, etc.) on the circuit board 4. The upper housing 12 forms a first accommodation space FSP. The upper housing 12 has an upper body 122 and a pressing member 124. In the present embodiment, the upper housing 12, the upper body 122 and the pressing member 124 are integrally formed and are made of metal.

[0073] For reference Figure 4a and Figure 4b , is to illustrate the present invention Figure 1 Side view of the upper housing. Figure 4a This invention is described Figure 1 Side view of the exterior of the upper housing and Figure 4b This invention is described Figure 1 Side view of the interior of the upper housing. Figure 4a In the embodiment, the pressing member 124 is formed on two sides of the upper body 122 through the opening 126. The reason for having the opening 126 is to allow the pressing member 124 to achieve the pressing function. The pressing member 124 also includes a first fixing member 1210. The first fixing member 1210 is formed on two sides of the upper body 122 and can be fixed to the circuit board 4. Here, the first fixing member 1210 can be connected to the ground terminal 42 of the circuit board 4 by welding or the like.

[0074] In addition, the upper housing 12 also includes a second fixing member 128, which is formed in the first accommodation space FSP of the upper housing 12. The second fixing member 128 is disposed in the opening 164 of the rubber core 16 mentioned later (refer to Figure 8) to limit the rubber core 16 in the first accommodating space FSP.

[0075] In addition, the upper housing 12 also includes a grounding member 1212 extending from the first accommodating space FSP of the upper housing 12 to connect to the grounding terminal 42 of the circuit board 4 or the grounding wire of the flat wire 2 .

[0076] In addition, the upper shell 12 also includes a first buckle 1214 formed on two sides of the upper body 122 to correspond to the second buckle 166 of the rubber core 16 mentioned later (refer to Figure 8 ), the first fastener 1214 acts on the second fastener 166, so that the upper shell 12 limits the rubber core 16 in the first accommodation space FSP, which can be referred to together Fig. 9 , is a side view showing the easy-lock connector with a push-to-unlock structure of the present invention.

[0077] For reference Figure 5 , is to show the present invention Figure 1 Schematic diagram of the structure of the lower shell. Figure 5 The lower housing 14 is disposed in the first accommodation space FSP. The lower housing 14 forms a second accommodation space SSP, which has an elastic member 142 , a stopper 144 , an extension arm 146 and a lower body 148 .

[0078] For reference Figure 6 , is a cross-sectional view showing the upper shell and the lower shell of the present invention. The elastic member 142 is respectively arranged on the two side edges of the lower body 148 and corresponds to the position of the pressing member 124. In the present embodiment, the elastic member 142 is a U-shaped body with an R angle, and one end thereof is arranged on the inner wall of the upper shell 12. For example, the R angle is greater than or equal to R0.1. In other embodiments, the R angle can be any value. The stopper 144 is arranged according to the notch 22 to snap into the notch 22, and the stopper 144 is connected to the elastic member 142 through the extension arm 146. Figure 6 In the embodiment, the upper shell 12 further includes a rib 1242, and the rib 1242 is arranged corresponding to the elastic member 142. The rib 1242 protrudes toward the first accommodation space FSP. When no external force is applied to the pressing member 124, the elastic member 142 and the pressing member 124 are not in contact. In other embodiments, the elastic member 142 and the pressing member 124 may be in contact.

[0079] In addition, the lower housing 14 may further include a grounding member 1410. The grounding member 1410 extends from the lower housing 14 toward the outside of the second accommodating space to connect the grounding terminal 42 of the circuit board 4.

[0080] In addition, the lower housing 14 may further include a second lower housing grounding member 1412 (see Fig.11The second lower housing grounding member 1412 is formed in the second accommodation space SSP. The second lower housing grounding member 1412 extends from the lower housing 14 toward the second accommodation space SSP so as to be able to contact the grounding wire of the flat wire 2.

[0081] For reference Figure 7 and Figure 8 . Figure 7 This invention shows Figure 1 The structural diagram of the rubber core and Figure 8 This invention shows Figure 1 A cross-sectional view of the rubber core.

[0082] exist Figure 7 In the embodiment, the rubber core 16 is disposed in the second accommodation space SSP. The rubber core 16 forms an insertion port 162, an action portion 165 and an opening portion 164. The insertion port 162 allows the flat wire 2 to be inserted and withdrawn. The action portion 165 is combined with the elastic member 142 and the opening portion 164 to dispose the elastic member 142. In this embodiment, the action portion 165 is a groove, and a slope 168 is formed in the groove (refer to Fig.11 ), when the upper shell 12 is combined with the rubber core 16, refer to Fig. 9 When the pressing member 124 of the upper housing 12 is subjected to external force, the pressing member 124 will sink into the groove until the pressing member 124 completely touches the inclined surface 168, that is, the pressing member 124 is attached to the inclined surface 168. The inclined surface 168 limits the movement of the pressing member 124, and the pressing depth of the pressing member 124 can be determined.

[0083] Therefore, when the flat wire 2 is introduced into the insertion port 162, the notch 22 touches the stopper 144, causing the extension arm 146 and the elastic member 142 to deform, and finally the stopper 144 locks the notch 22. After the notch 22 of the flat wire 2 is locked by the stopper 144, the pressing member 124 is pressed, so that the pressing member 124 applies an external force to the elastic member 142, thereby generating deformation on the elastic member 142. Since the deformation amount of the elastic member 142 is related to the slope of the inclined surface 168, the elastic member 142 links the extension arm 146 to cause the stopper 144 to move in one direction, so as to release the state where the stopper 144 locks the notch 22, thereby achieving the purpose of unlocking.

[0084] Please refer to Fig.10 , is a schematic structural diagram of an easy-lock connector with a push-to-unlock structure according to a second embodiment of the present invention. Fig.10 In the embodiment, the easy-lock connector 10 ′ with a push-to-unlock structure includes not only the upper housing 12 , the lower housing 14 , the rubber core 16 and the terminal 18 of the first embodiment, but also a shielding iron shell 20 .

[0085] The upper housing 12 , the lower housing 14 , the rubber core 16 and the terminal 18 are described above and will not be repeated herein.

[0086] The shielding iron shell 20 is disposed on the upper shell 12, and its structure can be referred to Fig.11 As stated, Fig.11 This invention shows Fig.10 Schematic diagram of the decomposition of. Fig.11 In the embodiment, the shielding iron shell 20 further includes a first external card 202, a first iron shell grounding 204 and an insert 206. The first external card 202 is formed on two sides of the shielding iron shell 20, and the first iron shell grounding 204 and the insert 206 are disposed adjacent to the insertion port 162 of the rubber core 16. The first iron shell grounding 204 can contact the grounding wire of the flat wire 2.

[0087] Furthermore, the upper shell 12 further includes a second external card 1216 and the plastic core 16 further includes a plug hole 1610 and a grounding opening 1612. The second external card 1216 is arranged corresponding to the first external card 202. The plug hole 1610 is arranged corresponding to the plug 206 and the grounding opening 1612 is arranged corresponding to the first iron shell grounding 204. Through the plug 206, the first external card 202, the second external card 1216 and the plug hole 1610, the shielding iron shell 20 covers the upper shell 12 and the plastic core 16.

[0088] For reference Fig.12 , is a schematic diagram illustrating the connection between the easy-lock connector with a push-to-unlock structure and a circuit board of the present invention. Fig.12 In addition to the upper shell 12, the lower shell 14, the rubber core 16, the terminal 18 and the shielding iron shell 20, the shielding iron shell 20 also includes a second shell grounding 208 and a third shell grounding 2010. The second shell grounding 208 and the third shell grounding 2010 are formed on the side edge of the shielding iron shell 20, and the second shell grounding 208 and the third shell grounding 2010 can contact the grounding terminal 42 of the circuit board 4. It is worth noting that the aforementioned structure of the plug-in 206, the first external card 202, the second external card 1216 and the socket 1610 can produce, for example, a floating effect in the up and down directions, that is, the first external card 202 and the second external card 1216 can be designed to provide, for example, a movable space. For example, the first external card 202 is an opening and the second external card 1216 is a protrusion. When the opening is larger than the protrusion, the protrusion can move in the opening, thereby allowing the second shell grounding 208 and the third shell grounding 2010 of the shielding iron shell 20 to adjust their positions along with the surface of the circuit board 4, so that they can be smoothly soldered to the circuit board 4.

[0089] Although the embodiments of the present invention are disclosed as described above, they are not intended to limit the present invention. Any person skilled in the relevant art may make slight changes to the shapes, structures, features, methods and quantities described in the claims of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the scope of the claims attached to this specification.
