Description

Technical Field

[0001] The utility model relates to an electric connector, and in particular to an electric connector capable of switching the conduction state between terminals. Background Art

[0002] Generally speaking, the adjacent terminal pieces of the plug-in connectors currently on the market are mainly constructed in a single stable state. For example, the positions of these terminal pieces are fixed, and the terminal pieces themselves cannot move, and they simply realize the plug-in between components to electrically connect the additional components. However, these terminal pieces that maintain a fixed state will have gaps in the structure between each other. The generation of gaps makes it easy for the plug-in connectors to fall off or peel off due to violent shaking or aging of the components during use. Therefore, the current plug-in connectors have insufficient structural stability. Furthermore, the conduction state between the terminals of the existing plug-in connectors is also fixed and cannot be changed. In summary, there is still room for further improvement in the existing plug-in connectors. Utility Model Content

[0005] According to one embodiment of the utility model, the utility model provides an electrical connector capable of switching the conduction state between terminals, which includes a circuit switching member, a first terminal member and two second terminal members. The circuit switching member has telescopic elasticity. The first terminal member is partially located in the upper part of the circuit switching member. The first terminal member has two extensions. The two extensions extend outward toward the lower part of the circuit switching member. The two second terminal members are arranged on opposite sides of the circuit switching member. Each of the two second terminal members has a main body and an elastic block arranged on the main body. The two second terminal members are separated from each other to define a plug-in opening. The plug-in opening is used to receive the plug-in. When the circuit switching member is driven downward by the plug-in to resist, the circuit switching member changes from the first state to the second state to change the conduction state between the first terminal member and the two second terminal members. In the first state, the two extensions contact the two elastic blocks respectively. In the second state, the two extensions are separated from the two elastic blocks respectively.

[0006] In one embodiment of the utility model, the circuit switching member has an elastic member and a plug-in portion, and the elastic member contacts and surrounds the lower portion of the plug-in portion. The first terminal member is partially located in the plug-in portion of the circuit switching member. The two extensions extend outside the plug-in portion in a vertical direction. The two extensions partially overlap the lower portion of the plug-in portion in a horizontal direction perpendicular to the vertical direction.

[0007] In one embodiment of the present invention, the first length of the elastic member in the first state is greater than the second length of the elastic member in the second state.

[0008] In one embodiment of the utility model, when the plug-in unit passes through the plug-in opening to drive the circuit switching unit to move downward in the vertical direction and resist the circuit switching unit, the two elastic blocks of the two second terminal units are separated from the two extensions of the first terminal unit, and the two second terminal units contact the plug-in unit.

[0009] In one embodiment of the present invention, two opposite sides of the plug-in portion of the circuit switching element are provided with grooves, and the two grooves extend in a vertical direction.

[0010] In one embodiment of the present invention, the first terminal member has a contact portion connecting the two extension portions, a portion of the contact portion connecting the two extension portions is located in the two grooves, and another portion of the contact portion is located on the top surface of the plug-in portion.

[0011] In one embodiment of the present invention, the two extension portions of the first terminal member have bent ends, and the two bent ends are respectively bent toward the adjacent elastic blocks, so that when the circuit switching member is in the first state, the two elastic blocks are respectively in contact with the two bent ends.

[0012] In one embodiment of the utility model, the main body of each of the two second terminal members is divided into a supporting portion and a bending portion connected to the supporting portion, the supporting portion has a hollow opening, and the opposite ends of the elastic block are bent from the hollow opening toward the circuit switching member, and the bending portion of each of the two second terminal members has a first part and a second part adjacent to the first part, and the bending direction of the first part is different from the bending direction of the second part.

[0013] According to another embodiment of the utility model, the utility model provides an electrical connector capable of switching the conduction state between terminals, which includes a circuit switching component and two terminal components. The circuit switching component has an elastic component and a plug-in portion connecting the elastic component. The two terminal components are partially located in the plug-in portion of the circuit switching component. Each of the two terminal components has a main body and an elastic block connecting the main body. The two main bodies are separated from each other to define a plug-in opening. The plug-in opening is used to receive a plug-in plug. When the two elastic blocks of the two terminal components contact each other to form a first circuit, the circuit switching component is in a first state. When the plug-in plug passes through the plug-in opening to abut against the circuit switching component, the plug-in plug drives the circuit switching component to move, so that the two elastic blocks are separated from each other, and the plug-in plug contacts the two main bodies to form a second circuit different from the first circuit, and the circuit switching component is in a second state.

[0014] In one embodiment of the present invention, the plug-in portion comprises a first plate and a second plate extending from the first plate. The first plate and the second plate define a receiving space, and a portion of the terminal is located in the receiving space.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the above-mentioned embodiment of the utility model, the circuit switching element of the electrical connector capable of switching the conduction state between the terminals can be changed from the first state to the second state to change the conduction state between the multiple terminal elements. Similarly, the circuit switching element can also be changed back to the first state from the second state. The configuration of the switchable conduction state between the multiple terminal elements allows the electrical connector capable of switching the conduction state between the terminals to have two states, normally open and normally closed, or, to have two different circuits. Therefore, when the electrical connector capable of switching the conduction state between the terminals is not connected to the plug-in, the multiple terminal elements are in contact with each other to improve the structural stability; and after the electrical connector capable of switching the conduction state between the terminals is connected to the plug-in, the multiple terminal elements do not contact each other, but can be electrically connected to the plug-in to form a path for circuit conduction.

[0065] Please refer to Figures 1 to 3 , Figure 1 This is a three-dimensional diagram of an electrical connector 100 capable of switching the conductive state between terminals according to an embodiment of the present invention and a plug-in 200 connected. Figure 2 1 is a perspective view of an electrical connector 100 capable of switching the conductive state between terminals according to an embodiment of the present invention, wherein the housing 115 is ignored. Figure 3 yes Figure 2 A side view of an electrical connector 100 that can switch the conductive state between terminals. Figures 1 to 3In the figure, an electrical connector 100 capable of switching the conduction state between terminals includes a circuit switching member 110, a first terminal member 120 and two second terminal members 130. The circuit switching member 110 has telescopic elasticity. A base 170 is provided below the circuit switching member 110. The base 170 is used to fix the circuit switching member 110 to move in the housing 160. The first terminal member 120 is partially located in the circuit switching member 110. The first terminal member 120 has two extensions 122. The two extensions 122 extend outwardly toward the circuit switching member 110. The two second terminal members 130 are arranged on opposite sides of the circuit switching member 110, for example, one second terminal member 130 is arranged on the left side of the circuit switching member 110, and the other second terminal member 130 is arranged on the right side of the circuit switching member 110.

[0066] In some embodiments, each second terminal member 130 has a main body 132 and an elastic block 134 disposed on the main body 132. The two second terminal members 130 are separated from each other to define a plug-in opening O1. The plug-in opening O1 can be used to receive the plug-in 200, wherein the plug-in 200 is made of a conductive material, but this is not limited to this and is determined by its application. In addition, the circuit switching member 110 has an elastic member 112 and a plug-in portion 114. For example, the elastic member 112 can be a telescopic spring, but this is not limited to this. The first terminal member 120 is partially located in the plug-in portion 114 of the circuit switching member 110.

[0067] In some embodiments, the two extension portions 122 of the first terminal member 120 have bent ends 123, and the two bent ends 123 are respectively bent toward the elastic blocks 134 adjacent thereto. When the circuit switching member 110 is in the first state, the two elastic blocks 134 of the second terminal member 130 respectively contact the two bent ends 123 of the first terminal member 120. The main body 132 of each second terminal member 130 is divided into a supporting portion 131 and a bent portion 133 connected to the supporting portion 131. The supporting portion 131 has a hollow opening C, and the opposite ends of the elastic block 134 are bent from the hollow opening C toward the circuit switching member 110. In addition, the bent portion 133 of the second terminal member 130 has a first portion 135 and a second portion 137 adjacent to the first portion 135. The bending direction of the first portion 135 is different from the bending direction of the second portion 137. For example, the first portion 135 has elastic characteristics, so when the plug-in 200 contacts the first portion 135 , the first portion 135 can move to two opposite sides, so that the plug-in 200 can pass through the plug-in opening O1 .

[0068] Please refer to Figure 4 and Figure 5 , Figure 4 and Figure 5It is a schematic diagram of an electrical connector 100 with switchable conductive state between terminals according to some embodiments of the utility model during operation. First, the two first elastic blocks 134 of the two second terminal members 130 can contact the two extensions 122 of the first terminal member 120 respectively, so that the two second terminal members 130 are electrically connected to the first terminal member 120, and the first circuit switching member 110 is in the first state at this time. Then, the plug-in 200 can be used to abut against the circuit switching member 110 through the plug-in opening O1, so that the plug-in 200 drives the circuit switching member 110 to move along the vertical direction D1 to resist the circuit switching member 110.

[0069] In some embodiments, when the circuit switching element 110 is driven downward by the plug-in 200 to resist, the circuit switching element 110 changes from the first state to the second state to change the conduction state between the first terminal 120 and the two second terminal 130. In the first state, the two extensions 122 contact the two elastic blocks 134 respectively to form a first circuit. In the second state, the two extensions 122 are separated from the two elastic blocks 134 respectively, and the plug-in 200 contacts the two second terminal 130 to form a second circuit. In addition, after the plug-in 200 is used and the plug-in 200 is withdrawn, the plug-in 200 can be separated from the electrical connector 100 that can switch the conduction state between the terminals to stay away from the plug-in opening O1.

[0070] In some embodiments, the first length H1 of the elastic member 112 in the first state is greater than the second length H2 of the elastic member 112 in the second state. That is, the first length H1 of the elastic member 112 when stretched is greater than the second length H2 of the elastic member 112 when compressed. In addition, when the plug-in 200 drives the circuit switching member 110 to move downward along the vertical direction D1 through the plug-in opening O1 and resists the circuit switching member 110, the two elastic blocks 134 of the two second terminal members 130 are separated from the two extension portions 122 of the first terminal member 120, and the two second terminal members 130 contact the plug-in 200.

[0071] In some embodiments, the plug-in portion 114 of the circuit switching member 110 has grooves 116 on opposite sides, and the two grooves 116 extend along the vertical direction D1. The first terminal member 120 has a contact portion 124 connecting the two extension portions 122. A portion of the contact portion 124 connecting the two extension portions 122 is located in the two grooves 116, and another portion of the contact portion 124 is located on the top surface 115 of the plug-in portion 114.

[0072] In some embodiments, the elastic member 112 contacts and surrounds the lower portion 118 of the plug-in portion 114. The first terminal member 120 is partially located in the upper portion 117 of the plug-in portion 114. The two extension portions 122 of the first terminal member 120 extend outward toward the lower portion 118 of the plug-in portion 114. The two extension portions 122 of the first terminal member 120 extend outside the plug-in portion 114 along the vertical direction D1. The two extension portions 122 of the first terminal member 120 partially overlap the lower portion 118 of the plug-in portion 114 in the horizontal direction D2 perpendicular to the vertical direction D1.

[0073] Specifically, the circuit switching element 110 of the electrical connector 100 capable of switching the conductive state between the terminals can be changed from the first state to the second state to change the conductive state between the first terminal 120 and the second terminal 130. Similarly, the circuit switching element 110 can also be changed from the second state back to the first state. The configuration of the switchable conductive state between the first terminal 120 and the second terminal 130 allows the electrical connector 100 capable of switching the conductive state between the terminals to have two states, namely, normally open and normally closed, or, alternatively, to have two different circuits. Therefore, when the electrical connector 100 capable of switching the conductive state between the terminals is not docked with the plug-in 200, the two extensions 122 contact the two elastic blocks 134 respectively to improve the structural stability. After the electrical connector 100 capable of switching the conductive state between the terminals is docked with the plug-in 200, the second terminal 130 can be electrically connected to the plug-in 200 to form a path for circuit conduction.

[0074] In the following description, another form of an electrical connector 100a capable of switching the conductive state between terminals will be described.

[0075] Please refer to Figures 6 to 8 , Figure 6 1 is a three-dimensional diagram of a circuit switching member 140 and a terminal member 150 of an electrical connector 100a capable of switching the conductive state between terminals according to another embodiment of the present invention. Figure 7 and Figure 8 It is a schematic diagram of an electrical connector 100a that can switch the conductive state between terminals according to other embodiments of the utility model during operation. The circuit switching member 140 has an elastic member 142 and a plug-in portion 144 connected to the elastic member 142. The elastic member 142 can be a telescopic spring. The terminal member 150 is partially located in the plug-in portion 144 of the circuit switching member 140. The terminal member 150 has a main body 152 and an elastic block 154 connected to the main body 152. The main bodies 152 are separated from each other to define a plug-in opening O2, which is used to receive the plug-in 300.

[0076] In some embodiments, when the two elastic blocks 154 of the terminal member 150 contact each other to form a circuit, the circuit switching member 140 is in the first state. When the plug-in 300 passes through the plug-in opening O2 to abut against the circuit switching member 140, the plug-in 300 can drive the circuit switching member 140 to move, so that the two elastic blocks 154 are separated from each other. The plug-in 300 contacts the main body 152 to form another circuit and the circuit switching member 140 is in the second state.

[0077] Please refer to Fig. 9 and Fig.10 , Fig. 9 1 is a perspective view of a circuit switching member 140 of an electrical connector 100a capable of switching the conductive state between terminals according to another embodiment of the present invention. Fig.10 It is a three-dimensional view of a terminal member 150 of an electrical connector 100a capable of switching the conductive state between terminals according to another embodiment of the present invention. The plug-in portion 144 of the circuit switching member 140 has a first plate 146 and a second plate 148 extending laterally from the first plate 146. The first plate 146 and the second plate 148 of the circuit switching member 140 define an accommodation space A. A portion of the terminal member 150 is located in the accommodation space A defined by the first plate 146 and the second plate 148.

[0078] Specifically, the circuit switching member 140 of the electrical connector 100a capable of switching the conductive state between terminals can be changed from the first state to the second state, and the circuit switching member 140 can also be changed from the second state back to the first state. When the electrical connector 100a capable of switching the conductive state between terminals is not docked with the plug-in 300, the two extensions 154 are in contact with each other to improve the structural stability. After the electrical connector 100a capable of switching the conductive state between terminals is docked with the plug-in 300, the two extensions 154 of the terminal member 150 are separated from each other, and the extensions 154 are electrically connected to the plug-in 300 to form a path for circuit conduction.

[0079] Please refer to Fig.11 , Fig.11 It is a stereoscopic view of a terminal member 150a according to yet another embodiment of the present invention. Fig.11 The terminal member 150a shown is Fig.10 The terminal 150 shown is different in that Fig.11 The extension portion 154a of the terminal piece 150a is located in the middle of the main body 152a, and Fig.10 The extension portion 154 of the terminal piece 150 is located at the end of the main body 152 .
