Description

Technical Field

[0001] The utility model relates to the technical field of instruments and equipment, in particular to a dual-channel output structure. Background Art

[0002] The high-power electrical measuring and testing instruments, power supplies, loads and other equipment currently used in the market usually have a single-channel output function at the output end of a device. Generally, a single-channel output has only one set of positive and negative copper electrodes arranged in parallel vertically from left to right, a set of positive and negative copper electrodes arranged horizontally from left to right, a set of positive and negative copper electrodes arranged horizontally from top to bottom, or a set of positive and negative copper electrodes arranged vertically from top to bottom.

[0003] There are few products on the market that can realize multi-channel output function in one device. Only low-current US standard terminal devices provide such function. However, in the field of high-voltage, high-current, high-power power supply or load equipment, there is no device with dual-channel output function, that is, two sets of positive and negative copper electrodes at the output end of a device. At present, it is usually necessary to use two single-channel devices in parallel to achieve the dual-channel output function.

[0004] In order to fill the gap of multi-channel output in the high-power field and provide users with a more flexible and efficient operation mode, the utility model provides a dual-channel output structure. Utility Model Content

The copper positive and negative electrodes of the dual channels are distributed in two rows, the upper two copper electrodes are the negative electrode of the first channel and the negative electrode of the second channel, and the lower two copper electrodes are the positive electrode of the first channel and the positive electrode of the second channel.

[0009] The copper positive and negative electrodes of the dual channels are staggered.

[0010] The positive electrode of the first channel and the negative electrode of the second channel are close to the middle part of the plastic terminal seat body, and the negative electrode of the first channel and the positive electrode of the second channel are close to the two ends of the plastic terminal seat body.

[0011] The positive electrode of the first channel and the negative electrode of the second channel near the middle part of the plastic terminal seat body are short electrodes, and the negative electrode of the first channel and the positive electrode of the second channel near the two ends of the plastic terminal seat body are long electrodes.

[0012] The parallel electrode is a rectangular sheet with holes at both ends, one end hole is used to lock and connect the positive electrode of the first channel, and the other end hole is used to lock and connect the positive electrode of the second channel, or one end hole is used to lock and connect the negative electrode of the first channel, and the other end hole is used to lock and connect the negative electrode of the second channel.

[0013] The series electrodes are in an overall Z-shape, with holes opened on the upper and lower end faces of the Z-shape, one end hole being used for locking and connecting the positive electrode of the first channel, and the other end hole being used for locking and connecting the negative electrode of the second channel.

[0015] 1. The utility model can realize the dual-channel output function of power supply or load equipment such as large current, high voltage and high power, filling the product gap in the current market where single-machine equipment cannot complete large current, high voltage and high power dual-channel output.

[0016] 2. The utility model designs a dual-channel output structure, which can not only expand the current and increase the power to realize the dual-channel parallel output function; but also increase the voltage and power to realize the dual-channel series output function.

The utility model can conveniently realize the parallel connection of the positive electrodes and the negative electrodes of the dual-channel copper electrodes through the staggered arrangement of the electrodes, and can also easily realize the series connection of the positive electrodes and the negative electrodes of the copper electrodes, which greatly improves the convenience of operation.

[0018] 4. The copper electrodes of the utility model are designed with two shorter ones in the middle and two longer ones near the sides, which is not only conducive to the direct wiring of the dual-channel copper electrodes in parallel and series, but also can avoid mutual interference and interference between the positive and negative electrodes of the copper electrodes, ensuring the stability and accuracy of the operation. At the same time, this design also reduces the risk of electrode deformation during operation, further improving the reliability of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0034] This embodiment provides an output structure for dual-channel parallel connection, which is composed of an output terminal seat, parallel electrodes, and screws. The parallel electrodes are locked to the output terminal seat by screws, and the output terminal seat can be inserted into the device body to achieve electrical connection.

[0035] Specifically, Figure 1 As shown, the output terminal block consists of a plastic terminal block body and two groups of copper positive and negative electrodes. The two groups of copper positive and negative electrodes constitute dual channels, namely the first channel and the second channel, both of which pass through the plastic terminal block body. The two groups of copper positive and negative electrodes are separated into two parts by the plastic terminal block body, one part is inserted into the device body to achieve connection, and the other part is locked and connected to the parallel electrode through screws.

[0036] More specifically, the two groups of copper positive and negative electrodes are divided into two rows, the upper row of two copper electrodes is the negative electrode, and the lower row of two copper electrodes is the positive electrode. Specifically, in the upper arrangement, the negative electrode includes a long electrode, i.e., the negative electrode of the first channel in the dual channel, and a short electrode, i.e., the negative electrode of the second channel in the dual channel, and in the lower arrangement, the positive electrode includes a short electrode, i.e., the positive electrode of the first channel in the dual channel, and a long electrode, i.e., the positive electrode of the second channel in the dual channel, the two long electrodes are close to the edge of the plastic terminal seat body, and the two short electrodes are close to the center of the plastic terminal seat body.

[0037] There are two parallel electrodes, such as Figure 2 , Figure 3 , Figure 4 As shown, they are all rectangular sheets with holes at both ends. The parallel electrodes are screwed to the output terminal block. More specifically, the two ends of one parallel electrode are screwed to the two negative electrodes of the output terminal block, and the two ends of the other parallel electrode are screwed to the two positive electrodes of the output terminal block.

[0038] The specific assembly process is as follows:

[0039] Insert the two sets of copper positive and negative electrodes into the plastic terminal seat, insert the two sets of copper positive and negative electrodes close to the device into the device body, and fix the plastic terminal seat body to the device body with screws to achieve dual-channel output function.

[0040] Use one parallel electrode to lock and connect the two negative electrodes of different lengths in the upper row, and use another parallel electrode to lock and connect the two positive electrodes of different lengths in the lower row.

[0041] In this embodiment, a plastic terminal block and two sets of copper positive and negative electrodes are provided. The two sets of copper positive and negative electrodes adopt an upper and lower staggered structure, so that a dual-channel output function can be realized in one device, satisfying the output function of using one device as two devices. At the same time, two sets of parallel rectangular sheet electrodes are respectively connected and locked with a row of two negative electrodes at the upper end of the output terminal block and a row of two positive electrodes at the lower end. It can meet the different needs of users and realize the function of expanding current and power output. Example 2

[0042] Reference Figure 5 and Figure 6 , which is different from Example 1, in this embodiment, the two groups of copper positive and negative electrodes are divided into two rows, the upper row of two copper electrodes is the negative electrode, and the lower row of two copper electrodes is the positive electrode. In the upper arrangement, the negative electrode includes two short electrodes of the same length, and in the lower arrangement, the positive electrode includes two short electrodes of the same length.

[0043] The rest are the same as in Example 1 and will not be described in detail. Example 3

[0044] This embodiment provides an output structure for dual-channel series connection, which is composed of an output terminal seat, a series electrode, and a screw. The series electrode is locked with the output terminal seat by the screw, and the output terminal seat can be inserted into the device body to realize electrical connection.

[0045] The output terminal block in this embodiment is the same as the output terminal block in Embodiment 1, and will not be described in detail here.

[0046] Different from the parallel electrodes in Example 1, the number of series electrodes in this embodiment is set to 1. Figure 7 As shown, the series electrodes are in a "Z" shape as a whole, with holes opened on the upper and lower ends of the "Z" shape. Figure 8 , Fig. 9 As shown, one end hole is used to lock and connect the positive electrode of the first channel, and the other end hole is used to lock and connect the negative electrode of the second channel. It is fixed by screws.

[0047] The specific assembly process is as follows:

[0048] 1. Insert two sets of copper positive and negative electrodes into the plastic terminal block, insert the two sets of copper positive and negative electrodes close to the device into the device body, and fix the plastic terminal block body to the device body with screws to achieve dual-channel output function.

[0049] 2. One end hole of the series electrode is used to connect the positive electrode of the first channel, and the other end hole is used to connect the negative electrode of the second channel. It is fixed by screws.

[0050] This embodiment provides a plastic terminal seat body and two sets of copper positive and negative electrodes, and the two sets of copper positive and negative electrodes adopt an upper and lower staggered structure, so that a dual-channel output function can be realized in one device, satisfying the output function of using one device as two devices. At the same time, by connecting and locking the "Z"-shaped electrode in series with the positive electrode of the first channel and the negative electrode of the second channel of the output terminal seat, the voltage and power output function can be increased according to the different needs of the user. Example 4

[0051] Reference Fig.10 and Fig.11 , which is different from Example 3, in this embodiment, the two groups of copper positive and negative electrodes are divided into two rows, the upper row of two copper electrodes is the negative electrode, and the lower row of two copper electrodes is the positive electrode. In the upper arrangement, the negative electrode includes two short electrodes of the same length, and in the lower arrangement, the positive electrode includes two short electrodes of the same length.

[0052] The rest are the same as those in Example 3 and will not be described in detail.

[0053] In combination with the above four embodiments, the utility model designs a dual-channel output structure:

[0054] In normal dual-channel mode: the two sets of positive and negative copper electrodes of the terminal block are of equal length or longer on both sides and shorter in the middle, and the object to be tested is normally connected to the two sets of positive and negative copper electrodes of the terminal block.

[0055] When the two groups of positive and negative copper electrodes of the terminal body are long on both sides and short in the middle, the object to be tested is connected to the long positive and negative copper electrodes on both sides of the body; when the two groups of positive and negative copper electrodes of the terminal body are equal in length, the object to be tested is connected to the parallel electrode end surfaces of the positive and negative copper electrodes on both sides of the body.

[0056] When the voltage and power output function is increased by series connection: the two sets of positive and negative copper electrodes of the terminal block are of equal length or longer on both sides and shorter in the middle, and the objects to be tested are normally connected to the positive and negative copper electrode ends on the outside of the two sets of positive and negative copper electrodes of the terminal block.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
