[0002] In related technologies, some samples require electrical connection to different test power supplies during testing. Specifically, the positive and negative leads of the sample are connected to the positive and negative leads of the test power supply, respectively. After connection, an electrical test is performed. After the test is completed, the connection is disconnected, and a different test power supply is used to repeat the electrical test.

[0003] However, the wiring method between the sample and the test power supply is cumbersome and poses certain safety hazards. Utility Model Content

[0004] In view of this, the embodiments of this application aim to provide a sample testing wiring fixture and testing device that can improve both safety and the convenience of wiring.

[0005] To achieve the above objectives, this application provides a sample testing wiring fixture, comprising:

[0006] Support components;

[0007] At least two wiring assemblies are disposed on the support member. Each wiring assembly includes a terminal post and an insulating wire fixing member. The terminal post has a first terminal portion and a second terminal portion. The insulating wire fixing member wraps around a portion of the terminal post and avoids the first terminal portion and the second terminal portion. The insulating wire fixing member constrains an external conductor so that the constrained conductor can at least make contact with the second terminal portion to achieve an electrical connection.

[0008] In one embodiment, the insulating wire fastener is sleeved on the terminal block;

[0009] One end of the terminal is located outside the insulating wire fastener to form the first wiring portion; and / or,

[0010] The insulating wire fastener has a clearance opening to avoid the terminal block, and the second wiring portion is exposed at the clearance opening; and / or,

[0011] The insulating wire fastener has two clearance openings to avoid the terminal block, with the first wiring portion exposed at one of the clearance openings and the second wiring portion exposed at the other clearance opening.

[0012] In one embodiment, the support member has through holes corresponding to the wiring assemblies one by one, and each wiring assembly is at least partially accommodated in the corresponding through hole.

[0013] In one embodiment, the insulating wire fastener is sleeved on the terminal post, with one end of the terminal post located outside the insulating wire fastener to form the first wiring portion, which is at least partially accommodated in the through hole.

[0014] In one embodiment, the insulating wire fixing member has a wire fixing groove.

[0015] In one embodiment, the insulating wire fastener is sleeved on the terminal post, and the insulating wire fastener has a clearance opening that avoids the terminal post and communicates with the wire fastening groove, with the second wiring portion exposed at the clearance opening.

[0016] In one embodiment, the second wiring portion has a slot that is exposed at the clearance opening.

[0017] In one embodiment, the number of the wiring components is an even number greater than 2, and the wiring components are arranged in pairs.

[0018] At least a portion of the wiring assemblies have insulating fasteners of a first color, while the insulating fasteners of the remaining wiring assemblies have a second color that is different from the first color.

[0019] This application provides a sample testing device, including the sample testing wiring fixture described above.

[0020] In one embodiment, the support has a sample receiving space, the first wiring portion faces or extends into the sample receiving space, and the second wiring portion is located on the side of the support away from the sample receiving space.

[0021] In one embodiment, the sample testing device further includes a housing with a sample holding space;

[0034] This application provides a sample testing wiring fixture. Please refer to [link / reference]. Figures 1 to 6 The sample test wiring fixture 10 includes a support member 11; at least two wiring assemblies 12 are disposed on the support member 11. The wiring assembly 12 includes a terminal post 121 and an insulating wire fixing member 122. The terminal post 121 has a first wiring portion 121a and a second wiring portion 121b. The insulating wire fixing member 122 wraps around a portion of the terminal post 121 and avoids the first wiring portion 121a and the second wiring portion 121b. The insulating wire fixing member 122 constrains the external wire so that the constrained wire can at least make contact with the second wiring portion 121b to achieve electrical connection.

[0035] The sample test wiring fixture 10 is used to achieve the electrical connection between the sample 30 and the test power supply.

[0036] The support member 11 provides support to the wiring assembly 12. The support member 11 may be... Figure 1 and Figure 5 The plate-shaped component shown can also be Figure 6 The example shown is a box-shaped structure with one side open. In other embodiments, the support member 11 can also be a closed box-shaped structure, an L-shaped member with two walls, or any other structure that can provide mounting walls.

[0037] Figure 6 The support member 11 shown is a box-shaped structure with one open side and multiple walls. The wiring assembly 12 is disposed on the same side wall of the support member 11; in other embodiments, the wiring assembly 12 may also be disposed on different walls.

[0038] In one embodiment, the wiring assembly 12 for connecting the positive terminal is disposed on one wall surface, and the wiring assembly 12 for connecting the negative terminal is disposed on another wall surface. Separating the positive and negative terminals helps to reduce the probability of accidental contact or connection.

[0039] The support member 11 is generally made of insulating material. For example, the support member 11 is made of materials such as bakelite.

[0040] A wiring assembly 12 is mounted on the support member 11. At least two wiring assemblies 12 are provided, one for connecting to the positive terminal and the other for connecting to the negative terminal. It can be understood that every two wiring assemblies 12 can be considered a pair, with the two assemblies 12 used to connect to the positive and negative terminals respectively.

[0041] The number of wiring components 12 is not less than two, and the number of wiring components 12 can be odd or even. When the number of wiring components 12 is odd, at least one wiring component 12 will remain as a spare. When the number of wiring components 12 is even, each pair of wiring components 12 can correspond to one sample 30.

[0042] The wiring assembly 12 includes a terminal block 121 and an insulated wire fastener 122. The terminal block 121 is mounted on the support member 11.

[0043] Terminal 121 is used to connect sample 30 and test power supply, and can be made of a conductive material. For example, terminal 121 is made of copper or the like.

[0044] The insulating wire fastener 122 is used to fix external wires and insulate them from the terminal block 121. The insulating wire fastener 122 is made of insulating material. For example, the insulating wire fastener 122 is made of plastic or the like.

[0045] Specifically, the terminal 121 has a first terminal portion 121a and a second terminal portion 121b. One of the first terminal portion 121a and the second terminal portion 121b is used for electrical connection with the wires of the sample 30, and the other of the first terminal portion 121a and the second terminal portion 121b is used for electrical connection with the wires of the test power supply. The insulating wire fastener 122 avoids the first terminal portion 121a and the second terminal portion 121b, that is, the insulating wire fastener 122 does not block the first terminal portion 121a and the second terminal portion 121b.

[0046] For example, the insulating wire fastener 122 may be located between the first wiring portion 121a and the second wiring portion 121b, separating the first wiring portion 121a and the second wiring portion 121b from each other.

[0047] The insulating wire fixing member 122 constrains the external wires so that at least one of the constrained wires can make contact with the second terminal 121b to achieve an electrical connection. This means that after the insulating wire fixing member 122 fixes the wires, at least one wire can make contact with the second terminal 121b and achieve an electrical connection through this contact. The wires electrically connected to the first terminal 121a can be constrained by the insulating wire fixing member 122, or they can be unconstrained by it. For example, Figure 3 The first terminal 121a is located at the end of the terminal 121, and the second terminal 121b is located on the side of the terminal 121. In use, the wires of the sample 30 can be soldered to the first terminal 121a, making the sample 30 conductive with the first terminal 121a. The insulating wire-fixing member 122 constrains the wires of the test power supply, causing the wires of the test power supply to contact the second terminal 121b, thereby achieving conductivity between the test power supply and the second terminal 121b.

[0048] In other embodiments, please refer to Figure 4The first terminal 121a and the second terminal 121b can be located on the side of the terminal 121 respectively. The insulating wire fixing member 122 can constrain the wires of the sample 30 and the wires of the test power supply respectively, so that the wires of the sample 30 are in contact with the first terminal 121a and the wires of the test power supply are in contact with the second terminal 121b, thereby realizing the conduction between the sample 30 and the first terminal 121a, and the conduction between the test power supply and the second terminal 121b.

[0049] The method by which the insulating wire-fixing component 122 constrains the conductor is not limited, for example... Figures 1 to 4 The insulating wire fixing member 122 shown has a wire fixing groove 1222. The wire is fixed by being snapped into the wire fixing groove 1222 to achieve constraint. In other embodiments, the insulating wire fixing member 122 may also be constructed with any other structure that can serve to fix the wire, such as a buckle.

[0050] In related technologies, when testing samples, the sample's leads are typically connected directly to the leads of different test power supplies. For example, the positive lead of the sample is soldered to the positive lead of the test power supply, and the negative lead of the sample is soldered to the negative lead of the test power supply. After connection, an electrical test is performed.

[0051] However, directly connecting the sample's lead wires to the test power supply's lead wires is cumbersome and poses safety hazards such as short circuits and arcing.

[0052] The sample testing wiring fixture 10 of this application embodiment is provided with a terminal 121 having a first terminal 121a and a second terminal 121b. One of the first terminal 121a and the second terminal 121b is used for electrical connection with the wire of the sample 30, and the other of the first terminal 121a and the second terminal 121b is used for electrical connection with the wire of the test power supply. That is, the sample 30 and the test power supply can be connected through the terminal 121. Since the insulating wire fixing member 122 can constrain the external wire and make the external wire electrically connected to the second terminal 121b through contact, compared with the related art where the wire of the test power supply is directly connected to the wire of the sample, the safety hazard of short circuit and arcing can be reduced, and the safety can be improved. In addition, fixing the wire to the insulating wire fixing member 122 can achieve stable conduction between the wire and the second terminal 121b. After the test is completed, it can be removed and replaced, which is convenient and quick to use, thereby improving the convenience of wiring.

[0053] In addition, in related technologies, to improve testing efficiency, multiple samples are tested simultaneously during actual testing. Each sample is connected to a different test power supply. After the test is completed, the connection is disconnected, and the above operation is repeated by replacing the corresponding test power supply.

[0054] However, this testing method can easily lead to multiple wires becoming tangled and intertwined, making it difficult to visually determine the correspondence between the sample and the test power supply. If an anomaly occurs, it is difficult to locate the anomaly immediately.

[0055] In this application, the sample test wiring fixture 10 can test at least two samples 30 by setting at least four wiring components 12. Since each sample 30 is connected to the corresponding test power supply through two corresponding wiring components 12, the correspondence between the sample and the test power supply can be directly determined through the two corresponding wiring components 12. If an abnormality occurs during the test, the abnormal sample 30 and / or test power supply can be directly located from the support 11 through the wiring components 12.

[0056] In one embodiment, the insulating wire fastener 122 is sleeved on the terminal post 121; one end of the terminal post 121 is located outside the insulating wire fastener 122 to form a first wiring portion 121a.

[0057] Specifically, the insulating wire fastener 122 covers a portion of the terminal 121. In the part of the terminal 121 that is not covered by the insulating wire fastener 122 and is exposed, there is an end of the terminal 121, which forms the first wiring portion 121a.

[0058] In one embodiment, the insulating wire fastener 122 has a clearance opening 1221 to avoid the terminal post 121, and the second wiring portion 121b is exposed at the clearance opening 1221.

[0059] Specifically, the insulating wire fastener 122 encloses the terminal 121, and an opening 1221 is provided on the insulating wire fastener 122. The opening 1221 exposes the terminal 121 to the outside, and the part of the terminal 121 exposed through the opening 1221 forms the second wiring portion 121b.

[0060] In one embodiment, the insulating wire fastener 122 is sleeved on the terminal post 121; one end of the terminal post 121 is located outside the insulating wire fastener 122 to form a first wiring portion 121a; the insulating wire fastener 122 has a clearance opening 1221 to avoid the terminal post 121, and a second wiring portion 121b is exposed at the clearance opening 1221.

[0061] Specifically Figure 3 The insulating wire fastener 122 shown is sleeved on one end of the terminal 121, so that one end and part of the side wall of the terminal 121 are covered. The other end of the terminal 121 forms a first connection portion 121a. A clearance opening 1221 is provided on the insulating wire fastener 122, and a second connection portion 121b is formed on the terminal 121 opposite to the clearance opening 1221.

[0062] In one embodiment, the two ends of the terminal 121 may be located outside the insulating wire fastener 122 to form a first wiring portion 121a and a second wiring portion 121b, respectively. That is, the insulating wire fastener 122 wraps around the side wall of the terminal 121, and the two ends of the terminal 121 are located outside the insulating wire fastener 122 to form a first wiring portion 121a and a second wiring portion 121b, respectively.

[0063] The sidewall of terminal 121 refers to the radial outer peripheral wall surface of terminal 121, which is adjacent to the end of terminal 121.

[0064] In one embodiment, the insulating wire fastener 122 has two clearance openings 1221 to avoid the terminal block, with a first terminal portion 121a exposed at one of the clearance openings 1221 and a second terminal portion 121b exposed at the other clearance opening 1221.

[0065] Specifically, please refer to Figure 4 The insulating wire fastener 122 can cover the surface of the terminal 121. Two clearance openings 1221 are provided on the insulating wire fastener 122, which expose the terminal 121 to the outside. The two exposed parts of the terminal 121 through the clearance openings 1221 respectively form a first wiring portion 121a and a second wiring portion 121b. The clearance openings 1221 can be directly opposite the end of the terminal 121 or directly opposite the side wall of the terminal 121.

[0066] In one implementation method, please refer to [link / reference needed]. Figure 3 and Figure 4 The insulating wire fixing component 122 is sleeved on the terminal post 121. The insulating wire fixing component 122 has a clearance opening 1221 that avoids the terminal post 121 and communicates with the wire fixing groove 1222. The second wiring part 121b is exposed at the clearance opening 1221.

[0067] A recess is constructed on the insulating wire fixing member 122 to form a wire fixing groove 1222. An avoidance opening 1221 is provided on the bottom or wall of the wire fixing groove 1222. The avoidance opening 1221 penetrates the insulating wire fixing member 122 to expose the terminal 121 to the outside. The position of the terminal 121 exposed through the avoidance opening 1221 is the second wiring part 121b.

[0068] In use, the test power supply wires are inserted into the wire mounting slot 1222, and the wires contact the second wiring portion 121b through the clearance opening 1221, thus establishing an electrical connection between the wires and the second wiring portion 121b. When replacing the test power supply, the electrical connection is disconnected by pulling the existing test power supply wires out of the wire mounting slot 1222, and the wires of the new test power supply are pressed into the wire mounting slot 1222 to establish an electrical connection between the replaced test power supply wires and the second wiring portion 121b. This convenient and quick installation and removal process improves testing efficiency.

[0069] In one embodiment, please refer to Figure 5 The support member 11 has through holes 111 corresponding to the wiring assemblies 12, and each wiring assembly 12 is at least partially accommodated in the corresponding through hole 111.

[0070] The support member 11 has through holes 111 extending through its own wall. The number of through holes 111 corresponds to the number of wiring assemblies 12. Each through hole 111 accommodates one wiring assembly 12.

[0071] Specifically, the wiring assembly 12 can be interference-fitted with the through hole 111, or it can be bonded to the inner wall of the through hole 111 and / or the outer surface of the support member 11 located around the through hole 111, so that the wiring assembly 12 is fixed inside the through hole 111.

[0072] The wiring assembly 12 may accommodate only a portion of the terminal 121 within the corresponding through hole 111, while the insulating wire fastener 122 is located outside the through hole 111. Alternatively, the wiring assembly 12 may accommodate both a portion of the terminal 121 and a portion of the insulating wire fastener 122 within the corresponding through hole 111. The wiring assembly 12 may also accommodate all the terminals within the corresponding through hole 111, with the insulating wire fastener 122 entirely located within the through hole 111.

[0073] In one implementation method, please refer to [link / reference needed]. Figure 3 and Figure 4 The second wiring portion 121b may also have a slot 1211, which is exposed at the clearance opening 1221.

[0074] The second wiring portion 121b has a recessed structure, forming a slot 1211, which can be used to engage with a conductor. The slot 1211 is exposed at the clearance opening 1221 and communicates with the wire fixing groove 1222. That is to say, the external wire is simultaneously inserted into the wire fixing groove 1222 and the slot 1211, thereby making the external wire more securely engaged.

[0075] In one implementation, please refer to Figure 3 and Figure 4 The number of wiring components 12 can be an even number greater than 2, and the wiring components 12 are arranged in pairs; at least a portion of the wiring components 12 have insulating wire fasteners 122 of a first color, and the insulating wire fasteners 122 of the remaining wiring components 12 have a second color different from the first color.

[0076] The number of wiring assemblies 12 is even, with two wiring assemblies 12 forming a group. In one group of wiring assemblies 12, one assembly connects the positive terminal of the test power supply to the positive terminal of the sample 30, and the other assembly connects the negative terminal of the test power supply to the negative terminal of the sample 30. The two wiring assemblies 12 in a group are arranged in a row or column, making the arrangement of the wiring assemblies 12 more regular and easier to distinguish.

[0077] In each group of wiring assemblies 12, the insulating wire fastener 122 of one wiring assembly 12 is a first color, and the insulating wire fastener 122 of the other wiring assembly 12 is a second color, different from the first color. The wiring assemblies 12 in each group with the first-colored insulating wire fastener 122 are used to connect to either the positive or negative terminal, while the wiring assemblies 12 with the second-colored insulating wire fastener 122 are used to connect to the other positive or negative terminal.

[0078] For example, the first color is red and the second color is black. Generally, the terminal 121 wrapped with the red insulating wire 122 is used to connect to the positive terminal, and the terminal 121 wrapped with the black insulating wire 122 is used to connect to the negative terminal.

[0079] By setting up insulating wire fasteners 122 of different colors to distinguish between positive and negative poles, personnel can clearly identify the corresponding polarity and avoid danger caused by reversing the positive and negative poles.

[0080] In one embodiment, information such as numbers and names can be pasted or sprayed on the support member 11 near each group of wiring components 12 to facilitate recording and identification.

[0081] This application also provides a sample testing device; please refer to [link / reference]. Figure 6 and Figure 7 The sample testing device includes the sample testing wiring fixture 10 as described above.

[0082] In one implementation method, please refer to [link / reference needed].

In other embodiments, the support member 11 is constructed as a closed box-shaped structure. The support member 11 has a sample receiving space, and a through hole 111 is formed in the support member 11, penetrating one side wall of the support member 11. The wiring assembly 12 is inserted into the through hole 111, such that the first wiring portion 121a faces or extends into the sample receiving space, and the second wiring portion 121b faces away from the sample receiving space and protrudes from the through hole 111.

[0084] When the sample 30 is tested, it is placed in the sample holding space, and the support 11 separates the sample 30 from the test power supply.

[0085] In one implementation method, please refer to [link / reference needed]. Figure 7 The sample testing device also includes a housing 20 with a sample holding space; the sample testing wiring fixture 10 is separated from the housing 20, and the housing 20 has an outlet 201 that communicates with the sample holding space; or, the housing 20 has an opening that communicates with the sample holding space, the support member 11 is placed over the opening, the first wiring part 121a faces or extends into the sample holding space, and the second wiring part 121b is located on the side of the support member 11 away from the sample holding space.

[0086] The sample testing device includes a sample testing wiring fixture 10 and a housing 20. The housing 20 has a sample holding space, in which the sample 30 is placed during testing. Figure 7 The housing 20 shown is separate from the sample testing wiring fixture 10. A wire outlet 201 is provided on the housing 20. The sample 30 located in the sample containing space leads the wire out of the housing 20 through the wire outlet 201 and connects to the sample testing wiring fixture 10.

The sample 30 is placed in the sample containing space, and the wires of the sample 30 are connected to the first wiring portion 121a. The wires of the test power supply located outside the housing 20 are in contact with the second wiring portion 121b.
