[0063] Reference Figures 1 to 6 As shown, this embodiment provides a contact structure, which includes a contact support 100, a card holder 200, and a normally closed contact assembly 300.

[0064] Specifically, the contact support 100 includes a main body 110 and a first support 120 disposed on the main body 110. The first support 120 is provided with a first mounting groove 121, which penetrates the main body 110 along the height direction of the contact support 100. The card holder 200 is detachably disposed on the main body 110, and at least a portion of the projection of the first mounting groove 121 along the height direction of the contact support 100 is located on the card holder 200. The normally closed contact assembly 300 includes a normally closed contact seat 310 and a normally closed contact 320 disposed on the normally closed contact seat 310. The normally closed contact seat 310 is slidably disposed in the first mounting groove 121 along the height direction of the contact support 100.

[0065] In this embodiment, since the first mounting groove 121 extends through the main body 110 along the height direction of the contact support 100, the normally closed contact seat 310 can be inserted into the first mounting groove 121 on the side of the main body 110 away from the first support 120, facilitating the installation of the normally closed contact seat 310. Furthermore, after the normally closed contact seat 310 is placed in the first mounting groove 121, the retainer 200 is installed on the main body 110 to prevent the normally closed contact seat 310 from detaching from the first mounting groove 121, facilitating the assembly of other components of the normally closed contact assembly 300 within the first mounting groove 121, and facilitating the assembly of the contact structure.

[0066] It can be understood that the first installation slot 121 is provided with a first sliding groove 1211 on both sides along the length direction of the contact support 100, and the normally closed contact seat 310 is in sliding fit with the two first sliding grooves 1211. Due to the limiting of the first sliding groove 1211, the normally closed contact seat 310 cannot be installed into the first installation slot 121 along the width direction of the contact support 100.

[0067] Exemplarily, both ends of the normally closed contact 320 protrude from the first installation slot 121 along the width direction of the contact support 100, and both ends of the normally closed contact 320 are provided with a normally closed contact point 321. The normally closed contact point 321 can be located on the side of the normally closed contact 320 away from the main body part 110. It can be understood that when the coil structure of the contactor provided with the contact structure is not powered, the normally closed contact point 321 is in contact and conduction with the corresponding static contact; when the coil structure of the contactor provided with the contact structure is powered, the normally closed contact point 321 is separated from the corresponding static contact.

[0068] Exemplarily, the part of the normally closed contact 320 located in the first installation slot 121 is provided with an abutting groove 322, the normally closed contact seat 310 extends into the abutting groove 322 and abuts against the groove wall of the abutting groove 322, effectively preventing the normally closed contact 320 from being separated from the normally closed contact seat 310. Exemplarily, the abutting groove 322 can be a V-shaped groove.

[0069] In the embodiment, referring to the normally closed contact assembly 300 shown in Figure 1 and Figure 3 The normally closed contact assembly 300 further includes a spring seat 330 and a first spring 340, the spring seat 330 is arranged in the first installation slot 121, and the first spring 340 is arranged between the normally closed contact seat 310 and the spring seat 330. The spring seat 330 provides stable support for the first spring 340, so that the first spring 340 always presses the normally closed contact seat 310. Exemplarily, when the coil structure of the contactor provided with the contact structure is not powered, a stable conduction is formed between the normally closed contact 320 and the corresponding static contact under the action of the first spring 340, and when the contact support 100 moves due to the opening and closing of the contactor, the first spring 340 can provide good buffering effect for the normally closed contact 320.

[0070] Exemplarily, the side of the spring seat 330 facing the main body part 110 can form a limiting fit along the height direction of the contact support 100 with the main body part 110, so as to realize the positioning assembly of the spring seat 330. Specifically, the spring seat 330 is provided with a limiting reverse buckle 331 on both sides along the width direction of the contact support 100, and the side of the limiting reverse buckle 331 facing the main body part 110 can form a limiting fit along the height direction of the contact support 100 with the main body part 110.

[0071] Exemplarily, the spring seat 330 and the first spring 340 can be assembled in the first mounting groove 121 along the width direction of the contact support 100.

[0072] Exemplarily, the contact support 100 comprises at least one first support part 120, for example, two to eight, and the normally closed contact assembly 300 and the card seat 200 are arranged one by one with the first support part 120.

[0073] In some embodiments, as shown in Figure 1 , Figure 4 and Figure 5 , the body part 110 is provided with a recess 111 on the side away from the first support part 120, the recess 111 is provided with a limiting groove 112 on both sides along the width direction of the contact support 100, the limiting groove 112 is arranged along the length direction of the contact support 100, the card seat 200 is arranged in the recess 111, and the card seat 200 is arranged in the limiting groove 112 on the corresponding side along the width direction of the contact support 100, respectively. The card seat 200 can slide into or out of the limiting groove 112 along the length direction of the contact support 100, facilitating the disassembly and assembly of the card seat 200. The recess 111 is in communication with the first mounting groove 121.

[0074] Exemplarily, the side of the spring seat 330 facing the recess 111 can extend into the recess 111.

[0075] In a feasible implementation, the limiting groove 112 is provided with a first clamping groove 113 on the groove wall, and the card seat 200 is provided with a first undercut 210 on both sides along the width direction of the contact support 100, respectively. The first undercut 210 is clamped with the first clamping groove 113 on the corresponding side, so that the card seat 200 is stably mounted on the body part 110. Exemplarily, the first undercut 210 can be arranged on the side of the card seat 200 away from the first support part 120.

[0076] In a feasible implementation, the side of the card seat 200 facing the first support part 120 is provided with a guide strip 220, the guide strip 220 is arranged along the length direction of the contact support 100, and the body part 110 is provided with a guide groove 114. The guide strip 220 is slidingly matched with the guide groove 114 to guide the sliding of the card seat 200 into the limiting groove 112, facilitating the assembly of the card seat 200. It can be understood that the card seat 200 can slide into the end of the limiting groove 112 facing the guide groove 114. Exemplarily, the guide strip 220 is provided with at least one, and the guide groove 114 is arranged one by one with the guide strip 220. In some embodiments, the guide strip 220 is provided with two and is arranged on both sides of the card seat 200 along the width direction of the contact support 100, respectively.

[0077] In other embodiments, as shown in Figure 1 and Figure 6As shown, the groove 111 has second slots (not shown) on both sides along the width direction of the contact support 100; the card holder 200 has buckles 230 on both sides along the width direction of the contact support 100, and the buckles 230 have second buckles 231. The card holder 200 is disposed in the groove 111, and the second buckles 231 engage with the second slots on the corresponding sides. In this embodiment, the buckles 230 can extend into the groove 111 along the height direction of the contact support 100 and engage with the second slots, which facilitates the installation of the card holder 200.

[0078] In this embodiment, reference is made to Figure 1 , Figure 5 and Figure 6 As shown, the side of the card holder 200 opposite to the first support portion 120 is used to hold the elastic member 201. In this embodiment, when the coil structure of the contactor equipped with the contact structure and the elastic member 201 is not energized, the contact support 100 is held in a high position under the action of the elastic member 201, and the normally closed contact 320 is connected to the corresponding stationary contact; when the coil structure of the contactor equipped with the contact structure and the elastic member 201 is energized, the contact support 100 is held in a low position, and the normally closed contact 320 is separated from the corresponding stationary contact.

[0079] For example, the elastic element 201 can be a spring.

[0080] In some embodiments, such as Figure 5 and Figure 6 As shown, a support post 240 is provided on the side of the card holder 200 opposite to the first support part 120. The support post 240 is used to connect the elastic member 201. Exemplarily, the elastic member 201 is sleeved on the support post 240, which facilitates assembly and ensures a stable and reliable connection.

[0081] In other embodiments, the card holder 200 is provided with a first support groove (not shown) on the side opposite to the first support portion 120. The first support groove is used to accommodate one end of the elastic member 201, which facilitates the assembly of the elastic member 201 and ensures a stable and reliable connection.

[0082] In this embodiment, reference is made to Figure 1 and Figure 4 As shown, the contact support 100 also includes a second support portion 130 provided on the main body portion 110. The second support portion 130 is provided with a second mounting groove 131, which passes through one end of the second support portion 130 away from the main body portion 110.

[0083] Specifically, the contact structure further comprises a normally open contact assembly 400 and a top support 500. The normally open contact assembly 400 comprises a normally open contact seat 410 and a normally open contact 420 arranged on the normally open contact seat 410, and the normally open contact seat 410 is arranged in the second mounting groove 131 in the height direction of the contact support 100. The top support 500 is detachably arranged at one end of the second support portion 130 away from the main body portion 110, and at least part of the projection of the second mounting groove 131 in the height direction of the contact support 100 is located on the top support 500.

[0084] In the embodiment, since the second mounting groove 131 penetrates one end of the second support portion 130 away from the main body portion 110 in the height direction of the contact support 100, the normally open contact seat 410 can be inserted into the second mounting groove 131 at one end of the second support portion 130 away from the main body portion 110, facilitating the installation of the normally open contact seat 410. It can be understood that the second mounting groove 131 is provided with a second sliding groove (not shown) on both sides in the length direction of the contact support 100, and the normally open contact seat 410 is in second sliding fit with the two sliding grooves. Due to the limiting of the second sliding groove, the normally open contact seat 410 cannot be arranged in the second mounting groove 131 in the width direction of the contact support 100.

[0085] Exemplarily, both ends of the normally open contact 420 protrude from the second mounting groove 131 in the width direction of the contact support 100, and both ends of the normally open contact 420 are provided with normally open contacts (not shown). The normally open contacts can be located on the side of the normally open contact 420 facing the main body portion 110. It can be understood that when the coil structure of the contactor provided with the contact structure is not powered, the contact support 100 remains in the high position, and the normally open contacts are separated from the corresponding static contacts. When the coil structure of the contactor provided with the contact structure is powered, the contact support 100 remains in the low position, and the normally open contacts are in contact with the corresponding static contacts.

[0086] Exemplarily, the connection mode of the normally open contact 420 and the normally open contact seat 410 is the same as that of the normally closed contact 320 and the normally closed contact seat 310, and the present application will not be described in detail.

[0087] Specifically, the normally open contact assembly 400 further comprises a second spring (not shown) arranged between the normally open contact seat 410 and the top support 500. The top support 500 provides stable support for the second spring, so that the second spring always presses the normally open contact seat 410. Exemplarily, when the coil structure of the contactor provided with the contact structure is powered, a stable conduction is formed between the normally open contact 420 and the corresponding static contact, and when the contact support 100 moves due to the opening and closing of the contactor, the second spring can provide good buffering effect for the normally open contact 420.

[0088] In an embodiment, the top support 500 is clamped with the second support portion 130. For example, the second mounting slot 131 is provided with a third clamping slot 132 on both sides along the width direction of the contact support 100, and the top support 500 is provided with a third undercut 510 corresponding to the third clamping slot 132, the third undercut 510 extends into the second mounting slot 131 and is clamped with the corresponding third clamping slot 132, facilitating assembly.

[0089] In an embodiment, the top support 500 is not only clamped with the second support portion 130, but also clamped with the first support portion 120, to ensure that the connection between the top support 500 and the contact support 100 is stable and reliable. The clamping mode of the first support portion 120 and the second support portion 130 with the top support 500 can be the same.

[0090] For example, the contact support 100 includes at least one second support portion 130, for example, two to eight, and the normally open contact assembly 400 is provided one by one with the second support portion 130. For example, the top support 500 is provided with one, and it can be understood that the projections of all second mounting slots 131 along the height direction of the contact support 100 are located on the top support 500.

[0091] In an embodiment, the contact support 100 includes two first support portions 120 and two second support portions 130, and the two first support portions 120 are located between the two second support portions 130.

[0092] Referring to Figures 1 to 10 The embodiment also provides a contactor, which includes a base 610, a top cover 620, a coil structure, and the contact structure 800.

[0093] Specifically, the top cover 620 is arranged on the base 610 and forms a receiving cavity with the base 610; the contact structure 800 is arranged in the receiving cavity, and the contact structure 800 is in sliding connection with the top cover 620; the coil structure is arranged in the receiving cavity, and the coil structure is located on the side of the contact structure 800 facing the base 610. In the embodiment, the contact structure 800 is arranged to facilitate assembly of the contactor.

[0094] For example, the base 610 is provided with a second support slot (not shown) capable of accommodating the elastic member 201, facilitating assembly of the elastic member 201.

[0095] For example, the side of the limiting undercut 331 of the spring seat 330 facing the main body portion 110 abuts against the top cover 620 along the height direction of the contact support 100, that is, the spring seat 330 does not move with the contact support 100.

[0096] Exemplarily, the first armature 810 is connected to the side of the main body 110 away from the first support 120, and the coil structure includes a second armature 710, which magnetically attracts the first armature 810 when the coil structure is energized, so as to keep the contact support 100 in the low position. Exemplarily, the side of the second armature 710 facing the first armature 810 is provided with a magnetic separation plate 711.

[0097] Exemplarily, the first armature 810 can be fixed on the main body 110 by screw fastening.
