Description
Technical Field
[0001] This utility model relates to the field of electrical connector technology, specifically to a test terminal, a test terminal group, and a test terminal assembly. Background Technology
[0002] Insertion conductors and test terminals are generally used together. The test terminal includes a housing with a switching channel suitable for accommodating the insertion conductor. The switching channel has an opening, and the housing contains two conductive components located on opposite sides of the switching channel. The insertion conductor includes a working plug and a test plug (one for operation and one for testing). When the insertion conductor is accommodated in the switching channel, the two conductive components can establish a bridging connection through the insertion conductor.
[0003] However, during long-term use, the insertion conductor will be exposed to the external environment and will often encounter harsh environments (such as high temperature and humidity, low temperature, strong wind, etc.). Due to long-term exposure, the surface of the insertion end of the insertion conductor that contacts the test terminal may be damaged, or the surface may be damaged due to frequent insertion into the test terminal. As a result, the insertion end may not be able to conduct electricity with the electrical strip of the test terminal, and the insertion end may not be able to conduct electricity after entering the test terminal, which will affect the accuracy of automatic calibration. Utility Model Content
[0004] In view of this, the present invention provides a test terminal, a test terminal assembly, and a test terminal component to solve the problem that the plug of the test terminal assembly is damaged due to long-term exposure to the environment, such as damage to the surface of the insertion end in contact with the test terminal or damage to the surface of the insertion end due to frequent insertion into the test terminal. As a result, the insertion end cannot conduct electricity with the conductive strip of the test terminal, and the insertion end cannot conduct electricity when it enters the test terminal, which affects the accuracy of automatic calibration.
[0005] In a first aspect, this utility model provides a test terminal, comprising:
[0006] A housing having a switching channel adapted to accommodate an insertion conductor, the switching channel having an opening;
[0007] Two conductive components are spaced apart within the housing and located on both sides of the switching channel. Each conductive component includes a first electrical conductor.
[0008] A first conductive element is disposed within the switching channel;
[0009] Wherein, the two first electrical conductors have a first conductive state. In the first conductive state, the inserted conductive member enters the switching channel from the opening to contact the first electrical conductors on both sides respectively. Two conductive paths are formed between the two first electrical conductors. The first conductive path is the two first electrical conductors conductively connected through the first conductive member, and the second conductive path is the two first electrical conductors conductively connected through the inserted conductive member.
[0010] By setting up two conductive paths, even if the surface in contact with the first conductor is damaged, meaning the conductive path formed by the two first conductors electrically connected through the inserted conductive path cannot conduct electricity, the conductive path formed by the two first conductors through the first conductive path can still conduct electricity, thus achieving a "backup" of the conductive path and ensuring the accuracy of subsequent automatic verification.
[0011] In one optional embodiment, each of the conductive components further includes a movablely assembled second conductive member. In the first conductive state, the inserted conductive member drives the second conductive member to generate displacement linkage, forcing the corresponding first electrical conductor to form a contact conductive connection with the first conductive member, thereby forming a first conductive path. The two first electrical conductors each establish a bridging conductive connection with the inserted conductive member through the corresponding second conductive member, thereby forming a second conductive path.
[0012] In one optional embodiment, each of the conductive components further includes a second electrical conductor, and the two first electrical conductors have a second conductive state. In the second conductive state, the first electrical conductor establishes a bridging conductivity with the corresponding second electrical conductor through the corresponding second conductive member, thereby forming a third conductive path. In the first conductive state, the inserted conductive member drives the second conductive member to generate displacement linkage to disengage from the second electrical conductor, so that the first electrical conductor is disconnected from the corresponding second electrical conductor.
[0013] In one optional embodiment, two first electrical conductors are symmetrically arranged on both sides of the central axis of the switching channel. Each first electrical conductor includes a connected arc-shaped deformable section and a fixed end. The fixed end is fixed inside the housing and connected to a wiring component inside the housing. The arc-shaped deformable section deforms under force to contact the first conductive element. And / or, the bottom of the switching channel away from the opening is provided with a slot, and the first conductive element is disposed in the slot.
[0014] In one optional embodiment, one end of the second conductive member is a rotating end and the other end is a movable end. In the second conductive state, the movable end is electrically connected to the first electrical conductor and the second electrical conductor respectively. In the first conductive state, the inserted conductive member drives the second conductive member to generate displacement linkage, causing the movable end to rotate around the rotating end until the movable end disengages from the second electrical conductor. The rotating end has a receiving space, and the housing has a fixed shaft that passes through the receiving space. An elastic member is sleeved on the outer periphery of the fixed shaft, and the elastic member has a tendency to maintain the movable end electrically connected to the first electrical conductor and the second electrical conductor respectively.
[0015] In one optional embodiment, the second electrical conductor further includes a second contact end, a fixed portion, and a movable portion. The fixed portion is fixedly connected to the second contact end and is fixedly disposed within the housing. The fixed portion is fixedly connected to the end of the movable portion, and a portion of the movable portion extends into the switching channel. In the first conductive state, the movable portion abuts against the inserted conductive member to restrict the inserted conductive member from arbitrarily swaying within the switching channel.
[0016] Secondly, this utility model also provides a test terminal assembly, including the test terminals described above, and further including an insertion conductor, which is detachably accommodated within the switching channel of the test terminals.
[0017] In one optional embodiment, the insertion conductor has a connected conductive part and an insulating part. The conductive part is pointed. In the first conductive state, the two first electrical conductors establish a bridging conductivity through the conductive part, and the two sides of the insulating part are respectively in contact with a second electrical conductor.
[0018] Thirdly, the present invention also provides a test terminal assembly, including at least two of the above-mentioned test terminal groups, wherein at least two adjacent test terminal groups are electrically connected to each other through a bridging member.
[0019] In one optional embodiment, the housing has a first bridging hole on the side of the opening of the switching channel and a second bridging hole on the side of the housing opposite to the opening of the switching channel. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0034] The following is combined Figures 1 to 11 The following describes embodiments of the present invention.
[0035] According to an embodiment of the present invention, in one aspect, a test terminal is provided, comprising:
[0036] The housing 1 has a switching channel 103 adapted to accommodate the insertion conductor 201, and the switching channel 103 has an opening;
[0037] Two conductive components 3 are spaced apart inside the housing 1. The two conductive components 3 are located on both sides of the switching channel 103. Each conductive component 3 includes a first electrical conductor 301.
[0038] The first conductive element 4 is installed in the switching channel 103;
[0039] Among them, the two first electrical conductors 301 have a first conductive state. In the first conductive state, the inserted conductive member 201 enters the switching channel 103 from the opening to contact the first electrical conductors 301 on both sides respectively. Two conductive paths are formed between the two first electrical conductors 301. The first conductive path is that the two first electrical conductors 301 are electrically connected through the first conductive member 4, and the second conductive path is that the two first electrical conductors 301 are electrically connected through the inserted conductive member 201.
[0040] By setting up a first conductive path and a second conductive path, even if the surface of the insert conductive member 201 in contact with the first conductor is damaged, that is, the second conductive path formed by the two first electrical conductors 301 electrically connected through the insert conductive member 201 cannot conduct electricity, the two first electrical conductors 301 can still conduct electricity through the first conductive path formed by the first conductive member 4, thus realizing a "backup" of the conductive path, allowing the insert conductive member 201 to enter the housing 1 to conduct electricity, and ensuring the accuracy of subsequent automatic verification.
[0041] In one embodiment, such as Figure 3 , Figure 5 and Figure 8 As shown, each conductive component 3 also includes a movablely assembled second conductive member 302. In the first conductive state, the inserted conductive member 201 drives the second conductive member 302 to generate displacement linkage, forcing the corresponding first electrical conductor 301 to form contact conduction with the first conductive member 4, thereby forming a first conductive path. The two first electrical conductors 301 each establish bridging conduction with the inserted conductive member 201 through their respective second conductive members 302, thereby forming a second conductive path. By setting the second conductive member 302, the second conductive member 302, driven by the inserted conductive member 201, forms contact conduction between the first electrical conductor 301 and the first conductive member 4, forming a first conductive circuit; and the two first electrical conductors 301 establish bridging conduction with the inserted conductive member 201 through their respective second conductive members 302, forming a second conductive path.
[0042] In one embodiment, such as Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, each conductive component 3 also includes a second conductor 303. The two first conductors 301 have a second conductive state. In the second conductive state, the first conductor 301 establishes a bridging connection with the corresponding second conductor 303 through the corresponding second conductive element 302, thereby forming a third conductive path. In the first conductive state, inserting the conductive element 201 drives the second conductive element 302 to generate displacement linkage and disengage from the second conductor 303, causing the first conductor 301 to disconnect from the corresponding second conductor 303. In the first conductive state, the first conductor 301 is separated from the second conductive element 302 and cannot be electrically connected to the second conductor 303; in the second conductive state, the first conductor 301 is electrically connected to the corresponding second conductor 303 through the corresponding second conductive element, forming a third path, so as to realize the electrical connection and disconnection of the first conductor 301 and the second conductor 303 in different states.
[0043] In one embodiment, such as Figure 2 , Figure 3 and Figure 4 As shown, two first conductors 301 are symmetrically arranged on both sides of the central axis of the switching channel 103. Each first conductor 301 includes a connected arc-shaped deformable section 3012 and a fixed end 3011. The fixed end 3011 is fixed inside the housing 1 and connected to the connector 106 inside the housing 1. The arc-shaped deformable section 3012 deforms under force to contact the first conductive element 4. A slot is provided at the bottom of the switching channel 103 away from the opening, and the first conductive element 4 is disposed in the slot. Specifically, the arc-shaped deformable section 3012 is made of a conductive metal material (such as copper, aluminum, silver, etc.) and is elastically deformable. The housing 1 is made of an insulating material. It should be noted that the central axis of the switching channel 103 is also the central axis of the housing 1. Through the deformation of the arc-shaped deformable section 3012 under force, the connection with the first conductive element 4 is achieved, allowing the two first conductors 301 to contact the first conductive element 4 respectively, thus achieving circuit connectivity.
[0044] In this embodiment, as Figure 2 , Figure 3 As shown, the switching channel 103 is U-shaped, and the arc-shaped deformed segment 3012 is in contact with the first conductive element 4 in the first conductive state. Specifically, the first conductive element 4 is made of a metallic conductive material (such as copper, aluminum, silver, etc.), preferably copper. The first conductive element 4 is fixed by a slot, so that the arc-shaped deformed segment 3012 makes contact with the first conductive element 4 after elastic deformation and then connects.
[0045] In one embodiment, such as Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, one end of the second conductive member 302 is a rotating end 3022, and the other end is a movable end 3024. The movable end 3024 is electrically connected to the first electrical conductor 301 and the second electrical conductor 303, respectively. In the first conductive state, inserting the conductive member 201 drives the second conductive member 302 to generate displacement linkage, causing the movable end 3024 to rotate around the rotating end 3022 until the movable end 3024 disengages from the second electrical conductor 303. The rotating end 3022 has a receiving space. The housing 1 has a fixed shaft 104, which passes through the receiving space. An elastic member is sleeved on the outer periphery of the fixed shaft 104. The elastic member has a tendency to keep the movable end 3024 electrically connected to the first electrical conductor 301 and the second electrical conductor 303, respectively. Specifically, the elastic member is a torsion spring, and the second conductive member 302 is made of a metallic conductive material (such as copper, aluminum, silver, etc.), preferably copper. During the specific movement, the movable end 3024 rotates relative to the housing 1 with the rotating end 3022 as the center. The first side surface 3021 of the movable end 3024 is fitted with the first contact end 3013 of the first electrical conductor 301. By placing the elastic element into the receiving space, the rotating end 3022 is subjected to a restoring force during rotation, which facilitates the rotation end 3022 to return to its initial state. The first contact end 3013 and the first side surface 3021 of the movable end 3024 are in surface contact to ensure the stability of the movable end 3024 during rotation.
[0046] In this embodiment, as Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the second electrical conductor 303 is fixedly disposed within the housing 1, and the second contact end 3031 of the second electrical conductor 303 is fitted against the second side surface 3023 of the movable end 3024. Specifically, the second electrical conductor 303 is made of a metallic conductive material (such as copper, aluminum, silver, etc.), preferably copper. The first side surface 3021 of the second conductive member 302 is connected to the first electrical conductor 301, and the second side surface 3023 is connected to the second electrical conductor 303, thereby achieving bridging conductivity between the first electrical conductor 301 and the second electrical conductor 303, thus forming a third conductive path.
[0047] In one embodiment, such as Figure 2 , Figure 7 and Figure 8As shown, the second conductor 303 further includes a second contact end 3031, a fixing part 3032, and a movable part 3033. The fixing part 3032 is fixedly connected to the second contact end 3031 and is fixedly disposed within the housing 1. The fixing part 3032 is also fixedly connected to the end of the movable part 3033, with a portion of the movable part 3033 extending into the switching channel 103. The fixing part 3032 is fixed by the housing 1, and the portion of the movable part 3033 extending into the switching channel 103 facilitates contact with the insertion conductive member 201. It should be noted that in this embodiment, the second contact end 3031 of the second conductor 303 and the second side surface 3023 of the second conductive member 302 are in surface contact. It should also be noted that the first conductor 301 and the second conductor 303 are integrally formed to reduce processing difficulty.
[0048] According to an embodiment of this utility model, a test terminal assembly is also provided, such as... Figure 1 , Figure 9 , Figure 10 and Figure 11 As shown, the device includes the aforementioned test terminals and also includes an insertion conductor 201. The insertion conductor 201 is detachably housed within the switching channel 103 of the test terminals to enable the insertion conductor 201 to engage and disengage from the test terminals. Furthermore, the insertion conductor 201 is configured in a one-to-one correspondence with each test terminal, and the insertion conductor 201 extends into the switching channel 103 to drive the second conductor 302 to rotate.
[0049] In one embodiment, such as Figure 2 , Figure 8 and Figure 9 As shown, the insertion conductive member 201 has a connected conductive part 2011 and an insulating part 2012. The conductive part 2011 is pointed. In the first conductive state, the two first electrical conductors 301 establish a bridging conductivity through the conductive part 2011. The two sides of the insulating part 2012 are in contact with the movable part 3033 of a second electrical conductor 303. It should be noted that in this embodiment, the surface of the conductive part 2011 is a conductive surface and can conduct electricity, while the surface of the insulating part 2012 is an insulating surface and cannot conduct electricity. In this embodiment, in the first conductive state, the two inclined surfaces of the conductive part 2011 are respectively fitted with the contact surfaces 3025 of the movable ends 3024 of the two second conductive members 302, so as to drive the movable ends 3024 to rotate around the rotating end 3022. The surface-fitting contact ensures a stable electrical connection between the conductive part 2011 and the movable end 3024. In the specific implementation process, the conductive part 2011 and the insulating part 2012 of the inserted conductor 201 extend into the switching channel 103. The conductive part 2011 is in contact with the contact surface 3025 of the second conductor 302 to ensure the stability of the contact, and the insulating part 2012 prevents electrical conduction between the two second conductors 303.
[0050] In this embodiment, as Figure 9 As shown, the surface of the pointed conductive portion 2011 that contacts the second conductive member 302 is a first inclined surface, and the contact surface 3025 of the movable end 3024 of the second conductive member 302 is a second inclined surface, and the first and second inclined surfaces are adapted to each other; the movable portion 3033 of the second electrical conductor 303 is in line contact with the insulating portion 2012. Figure 9 As shown, the insertion conductor 201 also includes a first connecting part 2013, wherein the first connecting part 2013 is disposed outside the housing 1 and is connected to the insulating part 2012 by a first connecting plate.
[0051] According to an embodiment of the present invention, a test terminal assembly is also provided, including at least two test terminal groups, wherein at least two adjacent test terminal groups are electrically connected to each other through a bridging member.
[0052] In one embodiment, such as Figure 1 , Figure 10 and Figure 11 As shown, a first bridging hole 105 is provided on one side of the opening of the switching channel 103 in the housing 1, and a second bridging hole 101 is provided on the side of the housing 1 opposite to the opening of the switching channel 103. It should be noted that the housings 1 of adjacent test terminal groups are integrally formed, with a first bridging hole 105 on each side of the same housing 1. The first bridging holes 105 of the same housing 1 are connected to the first electrical conductor 301 and the second electrical conductor 303, respectively. The first bridging holes 105 on one side of adjacent housings 1 are interconnected through conductive lines. Figure 1 As shown, the test terminal group in this embodiment consists of four groups, namely, four test terminals and four insertion conductive parts 201. The housings of the four test terminals are integrally formed, and the four insertion conductive parts 201 are integrally formed.
[0053] In this embodiment, as Figure 1 , Figure 10 and Figure 11 As shown, four insertion conductive parts 201 form an insertion conductive assembly 2. Specifically, four first connecting parts 2013 are integrally formed, with the two outermost first connecting parts 2013 respectively connected to the second connecting parts 2022 of the protective part 202. The first connecting parts 2013 and the second connecting parts 2022 are also integrally formed. To achieve the snap-fit connection between the insertion assembly and the housing 1, the first connecting part 2013 is provided with a first latch 2014, and the second connecting part 2022 is provided with a second latch 2021. The first latch 2014 and the second latch 2021 are respectively snap-fitted into the slots within the housing 1. It should be noted that, except for the conductive part 2011, the remaining parts of the insertion conductive parts 201 are made of insulating material.
[0054] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a first bridging hole 105 is provided on each side of the switching channel 103 within the same housing 1. A conductive wire is threaded through each first bridging hole 105 to connect to a bridging component located within the housing 1. The bridging component is connected to the fixing part 3032 of a second electrical conductor 303. A second bridging hole 101 is also provided on each side of the same housing 1. A conductive wire is threaded through each second bridging hole 101 to connect to a connector 106 within the housing 1. The connector 106 is connected to the fixing end 3011 of a first electrical conductor 301. Figure 1 , Figure 2 As shown, each side of the same housing 1 has a wiring hole 102. A conductive wire is threaded through each wiring hole 102 and connected to a corresponding connector 106. It should be noted that both the bridging connector and the connector 106 are made of conductive metal. Figure 1 As shown, the top of the housing 1 is also provided with a marking part 107 so that personnel can attach labels at the marking part 107.
[0055] In the specific implementation process, the test terminal has two conduction states, namely, the first conduction state and the second conduction state.
[0056] In the first conducting state, the inserted conductive member 201 is driven into the switching channel 103. As the conductive part 2011 slowly enters the switching channel 103, its two surfaces come into contact with the contact surfaces 3025 of the movable ends 3024 on both sides of the switching channel 103. This causes the movable end 3024 of the second conductive member 302 to rotate about the rotating end 3022 towards the first conductive member 4, separating the second side 3023 of the second conductive member 302 from the second contact end 3031 of the second conductor 303. Simultaneously, the first contact end 3013 of the first conductor 301 is subjected to the influence of the movable end 3024. The drive causes the arc-shaped deformation segment 3012 to undergo elastic deformation until the arc-shaped deformation segment 3012 contacts the first conductive member 4 (at this time, the two sides of the insulating part 2012 contact the movable part 3033 of the second electrical conductor 303 respectively, and the first buckle 2014 and the second buckle 2021 are respectively connected to the slot in the housing 1), thereby forming two paths. The first conductive path is the two first electrical conductors 301 connected through the first conductive member 4, and the second conductive path is the two first electrical conductors 301 connected through the inserted conductive member 201, that is, a conductive state is formed by the two first electrical conductors 301 connected.
[0057] In the second conductive state, the inserted conductive member 201 is driven to move in the direction away from the switching channel 103 (the inserted conductive member 201 is pulled out of the housing 1), and the first latch 2014 and the second latch 2021 are separated from the slot respectively. The movable end 3024 of the second conductive member 302 is driven by the restoring force of the elastic member and rotates in the direction away from the first conductive member 4 with the rotating end 3022 as the center. The elastic deformation of the arc-shaped deformation section 3012 slowly disappears until the conductive part 2011 separates from the movable end 3024. At the same time, the second side 3023 of the second conductive member 302 is attached to the second contact end 3031 of the second electrical conductor 303. At this time, a third conductive path is formed on both sides of the housing 1 by the first electrical conductor 301, the second conductive member 302 and the second electrical conductor 303, that is, a conductive state is formed by the first electrical conductor 301 and the second electrical conductor 303.
[0058] It should be noted that in the first and second conductive states, conductive wires are inserted into the first bridging hole 105 and the second bridging hole 101 respectively, while conductive wires are not inserted into the wiring hole 102. Furthermore, the first bridging hole 105 on the same side of adjacent housing 1 is connected to the first bridging hole 105 by conductive wires, and the second bridging hole 101 on the same side of adjacent housing 1 is connected to the second bridging hole 101 by conductive wires. The conductive wires are then connected to external electrical devices so that the test terminal assembly can perform testing or operation.
[0059] The present invention has the following advantages: (1) By setting two conductive paths, even if the surface of the inserted conductive member 201 in contact with the first conductor is damaged, that is, the conductive path formed by the two first conductors 301 electrically connected by the inserted conductive member 201 cannot conduct electricity, the two first conductors 301 can still conduct electricity through the conductive path formed by the first conductive member 4, thus realizing the "backup" of the conductive path and ensuring the accuracy of subsequent automatic verification; (2) The inserted conductive member 201 can be inserted vertically into the switching channel 103, and can also be inserted vertically into the switching channel 103. (2) It can be inserted horizontally into the switching channel 103, and can also be inserted into the switching channel 103 at any angle, which has the advantage of wide applicability; (3) It can be connected to the conductive wire through the wiring hole 102 and the second bridging hole 101 respectively. When the second bridging hole 101 cannot be used, the conductive wire can be inserted through the wiring hole 102 to extend the overall service life; (4) The first buckle 2014 and the second buckle 2021 are provided to ensure the tightness of the connection between the inserted conductive component 2 and the housing 1 in the first conductive state; (5) The elastic element is provided to ensure the first electrical Conductor 301 and the second conductor 303 are connected in the second conducting state; (6) The first conducting element 4 and the second conducting element 302 are respectively located on both sides of the first conductor 301. In the first conducting state, the first conducting element 4 is fixedly set and the second conducting element 302 is fixed by the position restriction of the inserted conducting element 201, so that the first conducting element 4 and the second conducting element 302 apply pressure to the first conductor 301 from both sides, forming a cooperative clamping of the first conductor 301, ensuring that the first conductor 301 forms a connection with the first conducting element 4 and the second conducting element 302. Continuous electrical contact, the above-mentioned electrical contact method is particularly suitable for vibration conditions (such as mechanical equipment vibration, site vibration, etc.). Through the electrical contact method, a dynamic conductive interface with self-compensation function is formed under vibration conditions, thereby maintaining the contact stability of the conductive circuit under vibration conditions; (7) The insertion stroke of the insertion conductive member 201 of this application is relatively short, that is, it can be inserted to the position of the second conductive member 302 (because the distance between the two relatively set second conductive members 302 is shorter as it goes up), and it does not need to be inserted to the position of the first electrical conductor 301 as in the prior art.
[0060] As an alternative implementation, the number of test terminals can be 2, 3, 5 or even more.
[0061] As an alternative implementation, the first contact end 3013 and the first side surface 3021 of the movable end 3024 can also be point contact or line contact.
[0062] As an alternative implementation, the second contact end 3031 and the second side surface 3023 of the movable end 3024 can also be point contact or line contact.
[0063] As an alternative implementation, the insertion conductor 201 and the test terminal may not be configured to correspond one-to-one.
[0064] As an alternative implementation, the arc-shaped deformation segment 3012 is in contact with the first conductive member 4 after being deformed by force; or, the switching channel 103 is provided with a slot at the bottom away from the outlet, and the first conductive member 4 is disposed in the slot.
[0065] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
