At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship.

It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0024] Reference below Figures 1 to 3 , the utility model is further described as follows:

[0025] A circuit simulation board spring pin clamp device, comprising: an upper clamping part 1, a lower clamping part 2 and a spring part 3, wherein:

[0026] The upper clamping part 1 and the lower clamping part 2 are both provided with a protruding connection part 10, and the upper clamping part 1 and the lower clamping part 2 are rotatably connected together through the protruding connection part 10. A spring part 3 is also provided between the upper clamping part 1 and the lower clamping part 2, and both ends of the spring part 3 are respectively connected to the upper clamping part 1 and the lower clamping part 2;

[0027] A probe mechanism 11 is provided at one end of the upper clamping part 1 away from the spring part 3 , one end of the probe mechanism 11 is connected to one end of a wiring terminal 12 in an electrical connection manner, and the other end of the wiring terminal 12 is connected to a wiring harness.

[0028] In this embodiment, a spring ejector pin 111 is disposed at one end of the probe mechanism 11 away from the wiring terminal 12 .

[0029] During the simulation process, the circuit board to be simulated is clamped between the upper clamping part 1 and the lower frame part 2, so that it is fixed directly below the probe mechanism 11, and the corresponding contacts on the circuit board are made to correspond one to one with the spring ejector pins 111 on the probe mechanism 11. After the circuit board is fixed, the spring ejector pins 111 are pressed down, and the spring ejector pins 111 can be electrically connected to the corresponding contacts on the circuit board while fixing the circuit board. When the simulation is completed or other circuit boards to be simulated are switched, the spring part 3 is directly pressed down to release the circuit board interface, which is convenient, fast and reliable.

[0030] In this embodiment, the tip of the spring ejector pin 111 is designed to be conical, which can be reliably connected to the circuit board hole.

[0031] In an optional implementation, the tip of the spring pin 111 is gold-plated to reduce the resistance at the connection between the spring pin 111 and the circuit board, which is more suitable for situations with larger currents.

[0032] The number of spring pins 111 is consistent with the number of pins of the connection terminal 12, and the number can be set according to actual needs, usually including a power supply terminal, a ground terminal, a simulation interface terminal, a communication interface terminal, etc.

[0033] In this embodiment, a fixing device 13 is provided at one end of the upper clamping part 1 away from the probe mechanism 11. In actual operation, the fixing device 13 can fix the wire harness connected to the wiring terminal 12 to the upper clamping part, so as to prevent the wire harness from moving randomly and affecting the simulation operation, and also to avoid the problem of the wire harness being easily broken due to the frequent movement of the wire harness, thereby increasing the service life of the wire harness.

[0034] In this embodiment, the spring part 3 is a compression spring, and the elastic force of the spring enables one end of the circuit simulation board spring needle clamp device in the present application to tightly clamp the circuit board to be simulated.

[0035] In an optional embodiment, the spring portion 3 is a torsion spring, which can achieve the same technical effect as a compression spring.

[0036] In this embodiment, the fixing device 13 is detachably connected to the upper clamping part 1. When the wiring harness needs to be replaced, the fixing device 13 can be removed. After the wiring harness is replaced, the fixing device 13 can be reinstalled, which provides convenience for adjustment and maintenance of the equipment.

[0037] In this embodiment, a gasket 21 is provided on the side of the lower clamping part 2 away from the spring part 3 and close to the upper clamping part 1. The gasket 21 is detachably connected to the lower clamping part 2. The provision of the gasket 21 can increase the contact area between the lower clamping part 2 and the circuit board, thereby achieving a better fixing effect. Moreover, during long-term use, when the gasket 21 is worn, the gasket 21 can be removed and replaced with a new gasket 21.

[0038] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0039] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0040] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0041] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
