Description

Technical Field

[0001] This utility model relates to the field of power connectors, and in particular to a connector device with quick locking and unlocking functions. Background Technology

[0002] Connectors are connectors that connect two active devices to transmit current or signals, and are key products for ensuring the correctness and reliability of electrical signal transmission. Quick locking and easy unlocking can greatly improve work efficiency; however, existing connector unlocking structures require tools or manual action on the connector, which cannot be achieved if the tool is loose, making it inconvenient to remove the connector, limiting its application scenarios, and causing inconvenience in operation.

[0003] Therefore, it is necessary to provide a connector device with fast locking and unlocking functions to solve the above-mentioned technical problems. Utility Model Content

[0004] In order to overcome the problems of slow unlocking speed, or even no unlocking at all, limited application scenarios, and inconvenient operation of existing connector locking or unlocking structures, this utility model provides a connector device with fast locking and unlocking functions.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solutions:

[0006] A connector device with quick locking and unlocking functions includes a plug shell, a middle shell, an arc-shaped spring, and a mating shell. The plug shell, middle shell, and mating shell are arranged on the same axis and have cavities inside for installing copper pin mounting seats and copper pins. The outer surface of the plug shell has at least one locking groove. One side of the locking groove has an unlocking slot. One end of the inner wall of the middle shell has a locking part equal in number and position to the locking grooves, and the other end has a spring-supporting post. The outer surface of the mating shell has at least one locking post groove, with a blocking part between each groove. The arc-shaped spring is installed in one of the locking post grooves, and the blocking part can block the spring-supporting post. The arc-shaped spring and the spring-supporting post have the function of positioning and locking the locking part in the locking groove, so that the plug shell can be quickly locked with the middle shell and the mating shell. Rotating the middle shell can rotate the locking part into the unlocking slot, so that the plug shell can be quickly unlocked from the middle shell and the mating shell.

[0007] As a further embodiment of this utility model: the groove wall of the locking post groove is provided with an installation groove for inserting the spring abutment post into the locking post groove. The installation groove facilitates the installation of the spring abutment post into the locking post groove.

[0008] As a further embodiment of this utility model: the spring-supporting column can enter the locking column groove from the mounting groove, and then rotate with the blocking part through an interference fit to enter the locking column groove on another adjacent groove wall that has no mounting groove or a misaligned mounting groove. This helps to prevent the middle shell from easily disengaging from the interlocking shell, and facilitates quick locking and unlocking.

[0009] As a further embodiment of this utility model: the middle shell is provided with at least one locking post on the same circle as the spring abutment post, and there are at least three locking post slots. The number of mounting slots on the groove wall of the locking post slot is less than the number of locking post slots, so that the spring abutment post and the locking post are locked in the locking post slot, ensuring that the middle shell and the interlocking shell do not easily separate, and facilitating the quick locking or unlocking of the interlocking shell with the middle shell and the interlocking shell.

[0010] As a further embodiment of this utility model: the blocking part and the locking post are respectively provided with a guide inclined surface on the same side as the unlocking through groove, so as to facilitate the spring holding post and the locking post to rotate into the adjacent locking post groove.

[0011] As a further embodiment of this utility model: the plug shell is axially provided with an interlocking guide groove having an inclined surface for interlocking guide grooves, the number of which is equal to the number of the locking grooves; at the same time, the locking part is provided with an interlocking guide inclined surface, so that the locking part can be easily inserted into the locking groove.

[0012] As a further embodiment of this utility model: an unlocking guide slope is provided on the side of the latch groove facing the unlocking through groove, and a middle shell unlocking guide slope is provided on the side of the latch part facing the unlocking through groove, so as to facilitate easy unlocking of the latch part.

[0013] As a further embodiment of this utility model: a spring positioning post is provided on the blocking part to facilitate the positioning of the arc-shaped spring.

[0014] As a further embodiment of this utility model: a first spring blocking part and a second spring blocking part are provided at the other end of the same locking groove as the spring positioning post, which are used to block the arc spring, so as to keep the plug shell and the middle shell and the plug shell locked and unlocked.

[0015] As a further embodiment of this utility model: an unlocking guide mark is provided on the outer surface of the middle shell to facilitate indicating the unlocking direction.

[0016] The beneficial effects of the connector device with quick locking and unlocking functions involved in this utility model are as follows:

[0017] Because a spring-loaded retaining post is provided on the inner surface of the middle shell, and a locking part is provided at the other end; at least one locking groove is axially provided on the outer surface of the insert shell, and a blocking part is provided between each groove. An arc-shaped spring is installed in one of the locking grooves, and the blocking part can block the spring-loaded retaining post; a locking groove is provided on the insert shell, and an unlocking through groove is provided on the other side. The middle shell can be pushed to lock the locking part in the locking groove to achieve the locked state; rotating the middle shell can rotate the locking part to the unlocking through groove to achieve the unlocked state; in addition, because the blocking part can block the spring-loaded retaining post, the middle shell can only rotate in the unlocking direction and cannot rotate in the opposite direction. With the action of the arc-shaped spring, the insert shell and the middle shell and the insert shell can be quickly locked and unlocked. Attached Figure Description

[0037] Example 1

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 11 , Figure 13 , Figure 15As shown, a connector device with quick locking and unlocking functions includes a plug shell 100, a middle shell 200, an arc spring 300, and a mating shell 400. The plug shell 100, the middle shell 200, and the mating shell 400 are arranged on the same axis. Specifically, the plug shell 100, the middle shell 200, and the mating shell 400 are all tubular structures with cavities inside for installing copper pin mounting seats 500 and copper pins 600. The outer surface of the plug shell 100 is provided with four locking grooves 132. 2. An unlocking slot 133 is provided on one side; one end of the inner wall of the middle shell 200 is provided with four locking parts 220 corresponding to the position of the locking slot 132, and the other end is provided with a spring-supporting post 250; the outer surface of the interlocking shell 400 is provided with six locking post slots 430 circumferentially, namely the first locking post slot 43a, the second locking post slot 43b, the third locking post slot 43c, the fourth locking post slot 43d, the fifth locking post slot 43e, and the sixth locking post slot 43f. The length of each slot is different, and a blocking part is provided between each one. The components are designated as a first blocking part 43g, a second blocking part 43h, a third blocking part 43i, a fourth blocking part 43j, a fifth blocking part 43k, and a sixth blocking part 43m. The arc-shaped spring 300 is installed within the first locking groove 43a. The outer surface radii of the second blocking part 43h, the fourth blocking part 43j, and the fifth blocking part 43k are larger than the inner surface radius of the spring-supporting post 250, thus restricting the spring-supporting post 250 from rotating within the first locking groove 43a. After assembly, the arc-shaped spring 300... The locking part 220 is abutted and connected with the spring-supporting post 250. When in use, pushing the middle shell 200 can push the locking part 220 into the locking groove 132. Both have the function of positioning and locking the locking part 220 in the locking groove 132, so that the plug shell 100 can be quickly locked with the middle shell 200 and the plug shell 400. Rotating the middle shell 200 can rotate the locking part 220 into the unlocking through groove 133, so that the plug shell 100 can be quickly unlocked from the middle shell 200 and the plug shell 400.

[0039] The plug-in housing 100 sequentially includes a plug-in housing mounting part 110, a plug-in housing isolation part 120, and a plug-in housing body 130. The plug-in housing mounting part 110 has a backstop part 111 on its end face and anti-fouling strip 112 and fixing groove 113 on its inner sidewall for assembling the copper pin mounting seat 500. At the same time, the outer surface is provided with a plug-in housing threaded part 114.

[0040] The middle shell 200 includes a middle shell body 210, and the locking part 220 is provided with a locking mounting groove 240 on the radial outer layer. That is, a cavity is provided between the middle shell body 210 and the locking part 220, which facilitates better locking and unlocking of the locking part 220 and can also ensure the strength of the middle shell 200.

[0041] Because the spring-supporting post 250 is provided on the inner surface of the middle shell 200, and the other end is provided with a locking part 220; the outer surface of the insertion shell 400 is axially provided with 6 locking post grooves 430, and a blocking part is provided between each one. The arc-shaped spring 300 is installed in the first locking post groove 43a, and the second blocking part 43h can block the spring-supporting post 250. The spring-supporting post 250 is restricted to circumferential rotation in the first locking post groove 43a; the insertion shell 100 is provided with the locking groove 132, and the unlocking through groove 133 is provided on the other side. Pushing the middle shell 200 causes the latch 220 to engage in the latch groove 132, achieving a locked state. Rotating the middle shell 200 allows the latch 220 to rotate to the unlocking through groove 133, achieving an unlocked state. Additionally, since the second blocking part 43h can block the spring abutment post 250, the middle shell 200 can only rotate in the unlocking direction and cannot rotate in the opposite direction. Combined with the effect of the arc spring 300, the plug-in shell 100, the middle shell 200, and the plug-in shell 400 can be quickly locked and unlocked.

[0042] like Figure 7 , Figure 8 As shown, the mating shell 400 sequentially includes a mating shell threaded portion 410, a mating isolation portion 420, a locking post groove 430, and a mating shell mounting portion 440. The locking post groove 430 has a first mounting groove 43p on the groove wall near the mating shell mounting portion 440, which allows the spring abutment post 250 to be inserted into the locking post groove 430. The first mounting groove 43p facilitates the installation of the spring abutment post 250 into the locking post groove 430.

[0043] like Figure 7 , Figure 8 As shown, the spring-supporting post 250 can enter the locking post groove 430 from the mounting groove, and then rotate with the blocking part after interference fit to enter the locking post groove 430 on the adjacent groove wall where there is no mounting groove or misaligned mounting groove. This helps to prevent the middle shell 200 from easily disengaging from the interlocking shell 400, and facilitates quick locking and unlocking.

[0044] like Figure 7 , Figure 8 , Figure 9As shown, the middle shell 200 is provided with three locking posts 230 on the same circle as the spring abutment post 250. The number of mounting slots on the wall of the locking post slot 430 is four: a first mounting slot 43p, a second mounting slot 43q, a third mounting slot 43r, and a fourth mounting slot 43s. In use, the spring abutment post 250 and the three locking posts 230 are respectively inserted into the second locking post slot 43b, the third locking post slot 43c, the fifth locking post slot 43e, and the sixth locking post slot 43f through the first mounting slot 43p, the second mounting slot 43q, the third mounting slot 43r, and the fourth mounting slot 43s. Then, the middle shell 200 is rotated towards the unlocking through slot 133, positioning the three locking posts 230 against the second blocking part 43h, the fourth blocking part 43j, and the sixth locking post slot 43f, respectively. The five blocking parts 43k are interference-fitted and respectively rotate into the second locking slot 43b, the fourth locking slot 43d, and the fifth locking slot 43e. The spring-supporting post 250 rotates into the first mounting slot 43p. After the initial assembly of the middle shell 200 and the interlocking shell 400, according to the aforementioned interference fit, preferably, the locking post 230 adjacent to the spring-supporting post 250 in the opposite unlocking direction abuts against the second blocking part 43h, thereby ensuring that the middle shell 200 can only rotate in the unlocking direction. Simultaneously, the spring-supporting post 250 and the three locking posts 230 cannot simultaneously emerge from the four mounting slots, ensuring that the middle shell 200 and the interlocking shell 400 do not easily detach, increasing ease of use, and facilitating quick locking or unlocking of the interlocking shell 100 with the middle shell 200 and the interlocking shell 400.

[0045] like Figure 6 , Figure 7 , Figure 12 As shown, the second blocking part 43h, the fourth blocking part 43j, and the fifth blocking part 43k are respectively provided with a second blocking part guide slope 43h0, a fourth blocking part guide slope 43j0, and a fifth blocking part guide slope 43k0 in the direction of the unlocking through groove 133. The locking post 230 is provided with a locking post guide slope 23a on the same side as the unlocking through groove 133, so that the spring holding post 250 and the locking post 230 can rotate into the adjacent locking post groove 430.

[0046] like Figure 2 , Figure 3 , Figure 4 , Figure 10 , Figure 14 As shown, the plug-in housing 100 is axially provided with four interlocking guide grooves 131, which are equal in number to the number of locking grooves 132, and have interlocking guide groove slopes 131a. The locking grooves 132 and the interlocking guide grooves 131 are arranged on the same axis. At the same time, the locking part 220 is provided with an interlocking guide slope 22a, which facilitates the easy insertion of the locking part 220 into the locking groove 132.

[0047] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the latch groove 132 is provided with an unlocking guide slope 132a on the side facing the unlocking through groove 133, and the latch part 220 is provided with a middle shell unlocking guide slope 22b on the side facing the unlocking through groove 133, so that the latch part 220 can be easily unlocked.

[0048] like Figure 2 , Figure 7 , Figure 8 , Figure 10 , Figure 12 As shown, a spring positioning post 43n is provided on the first blocking part 43g facing the inside of the first locking post groove 43a, which facilitates the positioning of the arc spring 300.

[0049] like Figure 7 , Figure 8 , Figure 10 , Figure 12 As shown, at the other end of the same locking groove 430 as the spring positioning post 43n, there are a first spring blocking part 43t and a second spring blocking part 43u, which are used to abut against the arc-shaped spring 300, so as to keep the insertion shell 100 locked and unlocked from the middle shell 200 and the opposite insertion shell 400. Alternatively, the arc-shaped spring 300 can also abut against the sixth blocking part 43m in its thickened state.

[0050] like Figure 15 As shown, an unlocking guide mark 260 is provided on the outer surface of the middle shell 200 to indicate the unlocking direction.

[0051] Example 2

[0052] The difference between Embodiment 2 and Embodiment 1 is that the unlocking through groove 133 is located in the clockwise direction of the latch groove 132, instead of the counterclockwise direction as in Embodiment 1. The corresponding unlocking guide slope 132a, the middle shell unlocking guide slope 22b, the locking post guide slope 23a, the unlocking guide mark 260, the first blocking part guide slope 43g0, the second blocking part guide slope 43h0, the fourth blocking part guide slope 43j0, and the fifth blocking part guide slope 43k0 are all located in the clockwise direction.

[0053] The above description of the utility model is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
