Description

[0002] A connector terminal is an accessory used to make electrical connections, often found in connectors, to enable electrical connections between electronic devices and external devices.

[0003] In related technologies, in order to make the electrical connection between the two electrical connection protrusions of the connection terminal and the two electronic devices more secure, an elastic section is provided in the middle of the connection terminal. The elastic force of the elastic section allows the two electrical connection protrusions of the connection terminal to float up and down in the vertical direction, so that the electrical connection between the electrical connection protrusions of the connection terminal and the electronic devices can be more secure.

[0004] However, for some connectors, when in use, the two electrical connection protrusions of the connector terminals need to be connected to electronic devices in two different directions. Since the elastic segment in the existing connector terminals can only apply elastic force to the electrical connection protrusions in one direction, it is difficult for the connector terminals to be tightly electrically connected to two electronic devices in two directions at the same time.

[0030] The following is for reference. Figure 1 The connection terminal 100 of the first aspect of this utility model will be described in detail.

[0031] refer to Figure 1 According to a first aspect embodiment of the present invention, the connection terminal 100 includes a transition structure 110, a first elastic connection structure 120, and a second elastic connection structure 130. The first elastic connection structure 120 is connected to one end of the transition structure 110, and a first electrical connection protrusion 122 is formed at the end of the first elastic connection structure 120 away from the transition structure 110. Under the action of the elastic force of the first elastic connection structure 120 itself, the first electrical connection protrusion 122 can abut against the first electrical connector of the circuit board in a first direction. The second elastic connection structure 130 is connected to the other end of the transition structure 110, and a second electrical connection protrusion 132 is formed at the end of the second elastic connection structure 130 away from the transition structure 110. Under the action of the elastic force of the second elastic connection structure 130 itself, the second electrical connection protrusion 132 can abut against the second electrical connector of the socket in a second direction, and the second direction is spaced at a certain angle from the first direction.

[0032] For example, such as Figure 1 As shown, the first direction is vertical, and the second direction is left-right. A first electrical connection protrusion 122 is formed at the lower end of the first elastic connection structure 120, and a second electrical connection protrusion 132 is provided at the right end of the second elastic connection structure 130. When the connection terminal 100 in this embodiment is working, the lower end face of the first electrical connection protrusion 122 abuts against the first electrical connector on the circuit board, and the right end face of the second electrical connection protrusion 132 abuts against the second electrical connector of the socket.

[0033] It is understood that the first elastic connection structure 120 can provide a downward elastic force to the first electrical connection protrusion 122, so that the first electrical connection protrusion 122 can abut against the first electrical connector of the circuit board in the vertical direction, and the second elastic connection structure 130 can provide a rightward elastic force to the second electrical connection protrusion 132, so that the second electrical connection protrusion 132 can abut against the second electrical connector of the socket in the left and right direction; thus, when the connection terminal 100 of this utility model is in use, the two electrical connection protrusions can simultaneously abut against the electrical connectors in two directions respectively.

[0034] In some embodiments of the present invention, the first elastic connection structure 120 further includes a first elastic connection segment 121, which includes a plurality of elastic units 121a. The plurality of elastic units 121a are sequentially connected along the second direction, and the opposite ends of the elastic connection segment are respectively connected to the transition structure 110 and the second electrical connection protrusion 132.

[0035] For example, such as Figure 1As shown, the first elastic connection structure 120 includes a first elastic connection segment 121 and a first electrical connection protrusion 122. The first elastic connection segment 121 includes a plurality of elastic units 121a connected sequentially from left to right. The structure of the elastic unit 121a is roughly U-shaped. The elastic unit 121a located at the leftmost end is connected to the transition structure 110, and the elastic unit 121a located at the rightmost end is connected to the first electrical connection protrusion 122.

[0036] It is understandable that when the first electrical connection protrusion 122 abuts against the first electrical connector on the circuit board, the first electrical connection protrusion 122 pushes the first elastic connection segment 121 upward under the abutment of the first electrical connector, so that the first elastic connection segment 121 deforms and stores a certain elastic potential energy. Then, under the elastic force of the first elastic connection segment 121, the first electrical connection protrusion 122 can firmly abut against the first electrical connector in the vertical direction, thereby improving the stability of the electrical connection between the first electrical connection protrusion 122 and the first electrical connector.

[0037] It is understandable that, since the first elastic connecting segment 121 includes multiple elastic units 121a connected in sequence, when the connecting terminal 100 is installed in the core 200, a deformation space needs to be reserved in the core 200 so that the first elastic connecting segment 121 can deform smoothly. Correspondingly, the setting of the deformation space in the core 200 makes the stability of the connecting terminal 100 installed in the core 200 relatively low.

[0038] Based on the above problems, in some embodiments of this utility model, reference is made to... Figure 1 The transition structure 110 has a receiving groove 110a that opens in the first direction, and the first elastic connecting section 121 is received in the receiving groove 110a. The transition structure 110 is used to abut against the core 200.

[0039] It is understood that by providing a receiving groove 110a in the transition structure 110 and placing the first elastic connecting segment 121 in the receiving groove 110a, the receiving groove 110a can provide deformation space for the first elastic connecting segment 121. At the same time, since the transition structure 110 can abut against the core 200, the connecting terminal 100 can be stably installed in the core 200.

[0040] In some embodiments of this utility model, the transition structure 110 includes a first transition segment 111, a second transition segment 112, and a third transition segment 113. The two opposite ends of the second transition segment 112 are respectively connected to the same end of the first transition segment 111 and the third transition segment 113 in the second direction. The first transition segment 111, the second transition segment 112, and the third transition segment 113 together define a receiving groove 110a. The first elastic connecting segment 121 is connected to the first transition segment 111, and the second elastic connecting structure 130 is connected to the third transition segment 113.

[0041] For example, such as Figure 1 As shown, the transition structure 110 includes a first transition segment 111, a second transition segment 112, and a third transition segment 113. The first transition segment 111 and the third transition segment 113 both extend in the left-right direction, and the second transition segment 112 extends in the vertical direction. The left end of the first transition segment 111 is connected to the lower end of the second transition segment 112, and the left end of the third transition segment 113 is connected to the upper end of the second transition segment 112, so that the first transition segment 111, the second transition segment 112, and the third transition segment 113 together define a receiving groove 110a with the opening facing to the right. The left end of the first elastic connecting segment 121 is connected to the middle part of the first transition segment 111, and the right end of the first elastic connecting segment 121 is connected to the first electrical connection protrusion 122, and the first electrical connection protrusion 122 extends downward to extend out of the receiving groove 110a.

[0042] It is understood that since the transition structure 110 includes a first transition segment 111, a second transition segment 112 and a third transition segment 113, when the connection terminal 100 of this embodiment is applied in a connector, the end faces of the first transition segment 111, the second transition segment 112 and the third transition segment 113 facing away from the receiving groove 110a can all abut against the core 200, so that the transition structure 110 can be stably installed in the core 200, thereby improving the stability of the connection terminal 100 of this application installed in the core 200.

[0043] In some embodiments of this utility model, along the second direction, the length of the first transition segment 111 is less than the length of the third transition segment 113. A clearance notch 110b is formed on the side of the first transition segment 111 away from the second transition segment 112. The first electrical connection protrusion 122 passes through the clearance notch 110b and extends to the outside of the receiving groove 110a. The second elastic connection structure 130 is connected to the end of the third transition segment 113 away from the second transition segment 112.

[0044] For example, such as Figure 1As shown, the length of the first transition section 111 is less than the length of the third transition section 113, so that a clearance notch 110b is formed on the right side of the first transition section 111. The first electrical connection protrusion 122 passes downward through the clearance notch 110b and extends downward to the lower side of the receiving groove 110a. The second elastic connection structure 130 is connected to the right end of the third transition section 113.

[0045] Understandably, the design of the clearance notch 110b allows the connecting terminal 100 to be smaller in the left-right direction.

[0046] In some embodiments of the present invention, the second elastic connection structure 130 further includes a second elastic connection segment 131 extending along a first direction. The second elastic connection segment 131 is connected to the transition structure 110. The second electrical connection protrusion 132 is disposed at one end of the second elastic connection segment 131 away from the transition structure 110. The second elastic connection segment 131 is used to provide elastic force in a second direction to the second electrical connection protrusion 132.

[0047] For example, such as Figure 1 As shown; the second elastic connection structure 130 includes a second elastic connection segment 131 and a second electrical connection protrusion 132. The second elastic connection segment 131 extends vertically and its lower end is connected to the transition structure 110. The second electrical connection protrusion 132 is connected to the upper right end of the second elastic connection segment 131.

[0048] It is understandable that when the connecting terminal 100 abuts against the second electrical connector of the socket, the second electrical connection protrusion 132 moves to the left under the counter-pushing of the second electrical connector, so that the second elastic connecting segment 131 deflects to the left to store the elastic potential energy of the movement. Then, under the elastic force of the second elastic connecting segment 131, the second electrical connection protrusion 132 can firmly abut against the second electrical connector to the right, so as to improve the stability of the electrical connection between the second electrical connection protrusion 132 of the connecting terminal 100 and the second electrical connector.

[0049] The following is for reference. Figures 1 to 4 The connector of the second aspect embodiment of this utility model will be described in detail.

[0050] refer to Figure 2 The connector provided according to the second aspect of the present invention includes the connection terminal 100 provided in the first aspect of the present invention.

[0051] In some embodiments of this utility model, the connector further includes a core 200, which has an installation channel 210 that extends through the core 200. The two opposite ends of the installation channel 210 form a connection port 210a and a insertion port 210b, respectively. A connection terminal 100 passes through the installation channel 210. A first electrical connection protrusion 122 extends to the connection port 210a, and a second electrical connection protrusion 132 extends to the insertion port 210b.

[0052] For example, such as Figure 1 , Figure 3 and Figure 4 As shown, the core 200 has a vertically extending mounting channel 210. The upper end of the mounting channel 210 forms a plug interface 210b, and the lower end of the mounting channel 210 forms a connection port 210a. The connecting terminal 100 passes through the mounting channel 210. The first electrical connection protrusion 122 of the connecting terminal 100 extends downward to the connection port 210a, and the second electrical connection protrusion 132 of the connecting terminal 100 extends upward to the plug interface 210b. When the connector of this application is in operation, the lower end of the first electrical connection protrusion 122 abuts against the first electrical connector of the circuit board, and the horizontal end of the second electrical connection protrusion 132 abuts against the second electrical connector of the socket. Under the elastic force of the first elastic connection structure 120 itself, the first electrical connection protrusion 122 can firmly abut against the first electrical connector downward, and under the elastic force of the second elastic connection structure 130 itself, the second electrical connection protrusion 132 can firmly abut against the second electrical connector in the horizontal direction.

[0053] Understandably, due to the elastic force of the first elastic connection structure 120, the first electrical connection protrusion 122 can firmly abut against the first electrical connector downwards, and due to the elastic force of the second elastic connection structure 130, the second electrical connection protrusion 132 can firmly abut against the second electrical connector in the horizontal direction. Thus, when the connector of this application is installed on the circuit board, the first electrical connection protrusion 122 can be firmly connected to the first electrical connector on the circuit board under the elastic force of the first elastic connection structure 120. The operator does not need to solder the first electrical connection protrusion 122 to the first electrical connector, which makes the installation and removal of the connector of this application on the circuit board more convenient and improves the convenience and flexibility of the connector of this application when installation and removal are required during use.

[0054] In some embodiments of this utility model, reference is made to Figure 1 , Figure 3 and Figure 4The installation channel 210 includes a first through section 211, a second through section 212, and a third through section 213 connected in sequence. The end of the first through section 211 away from the second through section 212 forms a connection port 210a, and the end of the third through section 213 away from the second through section 212 forms a plug-in port 210b. A transition structure 110 is accommodated in the second through section 212 and abuts against the channel wall of the second through section 212. A receiving groove 110a is formed in the transition structure 110. The first elastic connecting section 121 of the first elastic connecting structure 120 is accommodated in the receiving groove 110a. The first electrical connecting protrusion 122 is slidably inserted in the first through section 211 in the vertical direction. The second elastic connecting structure 130 is inserted in the third through section 213, and there is a clearance gap between the second elastic connecting structure 130 and the channel wall of the third through section 213 in the left and right directions.

[0055] Understandably, since the transition structure 110 is accommodated within the second insertion section 212 and abuts against the channel wall of the second insertion section 212, the transition structure 110 can be stably installed within the core 200 under the limiting effect of the channel wall of the second insertion section 212. Since the transition structure 110 has a receiving groove 110a, the first elastic connecting section 121 can deform normally within the receiving groove 110a, so that the first electrical connection protrusion 122 can slide downward relative to the first insertion section 211 and firmly abut against the first electrical connector of the circuit board. Since the second elastic connecting structure 130 is inserted within the third insertion section 213, and there is a clearance between the second elastic connecting structure 130 and the channel wall of the third insertion section 213 in the left and right directions, the second elastic connecting structure 130 can deform smoothly in the left and right directions, so that the second electrical connection protrusion 132 of the second elastic connecting structure 130 can firmly abut against the second electrical connector of the socket in the left and right directions.

[0056] In some embodiments of this utility model, in order to make the transition structure 110 more securely installed within the second intersecting section 212, reference is made to... Figure 1 and Figure 3 The transition structure 110 also includes a snap-fit ​​section 114, which is located at the junction of the first transition section 111 and the second transition section 112. The channel wall of the second insertion section 212 is provided with a snap-fit ​​groove 220, and the snap-fit ​​section 114 snaps into the snap-fit ​​groove 220.

[0057] In some embodiments of this utility model, the core 200 is provided with two rows of mounting channels symmetrically distributed along the second direction. Each mounting channel group includes a plurality of mounting channels 210 spaced apart along the third direction. Each mounting channel 210 is provided with a connecting terminal 100. The third direction is spaced apart from the first direction and the second direction by a certain angle.

[0058] For example, such as Figure 3 and Figure 4 As shown, the core 200 has two rows of mounting channels symmetrically distributed in the left-right direction. Each row of mounting channels includes multiple mounting channels 210 spaced apart in the front-back direction. Each mounting channel 210 has a connecting terminal 100 passing through it.

[0059] It is understandable that, since the mounting channels 210 are symmetrically distributed in the left and right directions, and each mounting channel 210 has a connecting terminal 100, the connector has two rows of second electrical connection protrusions 132 distributed in the left and right directions. The two rows of second electrical connection protrusions 132 can respectively abut against the second electrical connector in the socket in the left and right directions.

[0060] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
