Specific embodiments

[0024] In order to further understand the characteristics, technical means and the specific purpose reached of the utility model, functions, the utility model is described in further detail below in conjunction with the specific embodiments and the accompanying drawings.

[0025] Refer to Figures 1-7As shown, the utility model provides a kind of control coil, including shell assembly 1, the outside of shell assembly 1 can also detachably set up conducting component 2, the inside of shell assembly 1 is provided with coil assembly 3, shell assembly 1 includes first shell 11 and second shell 12, the cavity capable of accommodating coil assembly 3 is formed between first shell 11 and second shell 12, first shell 11 and second shell 12 can be detachably connected, first shell 11 and second shell 12 are combined together by detachable connection, form a complete shell, protect the coil assembly 3 in inside from outside environment interference.Conducting component 2 is responsible for transmitting external power supply or signal to coil assembly 3, realizes the energization or signal receiving function of coil.Conducting component 2 detachable design is convenient to replace or repair.Limiting piece 13 is respectively arranged at the junction between first shell 11 and second shell 12, and clamping piece 14 for fixing first shell 11 and second shell 12 is slidably arranged on limiting piece 13.Coil assembly 3 is the core part of control coil, when energization, magnetic field or electromagnetic force will be generated, for realizing specific control function, such as driving mechanical parts, generating signal etc.Clamping piece 14 is used for fixing first shell 11 and second shell 12, to prevent first shell 11 and second shell 12 from loosening or separating during use.Through sliding clamping piece 14, the assembly and disassembly of first shell 11 and second shell 12 can be conveniently realized.

[0026] Slip groove 131 is formed on limiting piece 13 along its length direction, and convex strip capable of slidingly cooperating with slip groove 131 is further arranged on clamping piece 14.Slip groove 131 provides sliding track for clamping piece 14, so that clamping piece 14 can slide up and down along the direction of slip groove 131.Convex strip slidingly cooperates with slip groove 131, to ensure that clamping piece 14 remains stable during sliding and does not come off slip groove 131.The shape and size of convex strip should match slip groove 131, to realize close sliding cooperation.Collar bead 15 is movably arranged in the position close to the upper part of slip groove 131, and elastic structure capable of resetting collar bead 15 is further arranged in slip groove 131, which can block clamping piece 14 when collar bead 15 is popped up under the action of elastic structure, and can block further sliding of clamping piece 14 when collar bead 15 is popped up under the action of elastic structure, thereby playing the role of fixing clamping piece 14.The position of collar bead 15 and the arrangement of elastic structure ensure that clamping piece 14 can be firmly fixed at a specific position in slip groove 131 when needed.

[0027] Limiting piece 13 is arranged on first shell 11 and second shell 12, and slip groove 131 is formed on limiting piece 13.Convex block on clamping piece 14 slides in slip groove 131, to realize the stable splicing of first shell 11 and second shell 12.When first shell 11 and second shell 12 need to be disassembled, simply pull out clamping piece 14, and the two can be easily separated, which is convenient for subsequent maintenance and replacement operation.

[0028] When the sliding card 14 is needed, the action of the card 14 causes the card bead 15 to be pressed down, the elastic structure is compressed, and the card 14 can slide along the sliding groove 131. When the card 14 slides to the desired position, the external force disappears, the elastic structure returns to its original shape, pushes the card bead 15 to pop up, and blocks the further sliding of the card 14, thereby fixing it at a specific position in the sliding groove 131. This mechanism facilitates the assembly and disassembly of the card 14.

[0029] Example one: the elastic structure is a spring. The spring provides a continuous elastic force to the card bead 15, enabling the card bead 15 to remain in a popped-up state without external force. When the card bead 15 is pressed down by external force, the spring is compressed; once the external force disappears, the spring returns to its original state, pushing the card bead 15 to pop up.

[0030] Example two: the elastic structure is a spring leaf. The spring leaf has elasticity and can provide a continuous elastic force to the card bead 15, enabling the card bead 15 to remain in a popped-up state without external force. When the card bead 15 is pressed down by external force, the spring leaf will deform; once the external force disappears, the spring leaf will return to its original state, pushing the card bead 15 to pop up.

The conductive assembly 2 cooperates with the connecting piece 121, and the conductive assembly 2 is also provided with a clamping groove 211 corresponding to the buckle 1211. The buckle 1211 can be clamped in the clamping groove 211. The buckle 1211 is usually designed as a protrusion or hook shape with elasticity, which can be clamped into and fixed in the corresponding slot or hole. Here, the buckle 1211 is used to cooperate with the clamping groove 211 on the conductive assembly 2 to realize the tight connection of the two.

[0032] Align the conductive assembly 2 with the connecting piece 121 on the side of the second shell 12. Apply appropriate force so that the buckle 1211 can be clamped into the clamping groove 211 on the conductive assembly 2. The elastic design of the buckle 1211 ensures that it can be tightly clamped in the clamping groove 211, forming a stable connection.

[0033] The coil assembly 3 includes a support frame 31 arranged in the shell assembly 1, and the coil body 32 is clamped in the support frame 31. The coil body 32 is connected with a pin 321 for conducting electricity, and the pin 321 can extend into the plug-in 21.

[0034] The plug-in 21 is provided with at least two cables 22, and one end of the cable 22 is connected with a socket 221. The pin 321 can be inserted into the socket 221 for conducting electricity.

[0035] The connecting piece 121 can be inserted into the plug-in piece 21, and the buckle 1211 on the connecting piece 121 can be firmly buckled in the clamping groove 211 of the plug-in piece 21. Meanwhile, the pin 321 can be accurately inserted into the socket 221, thereby realizing reliable communication of the circuit.
