Description

Anti-misplug device and connector assembly

Technical Field

The utility model relates to a prevent mistake cartridge and put and connector assembly for connector assembly.

Background

An electronic connector is a conductor device for connecting electrical lines. The component can be used as a terminal for connecting different elements in a circuit system, or can be used for providing power and data connection between different circuit systems and devices. It is widely used in various electric lines to connect or disconnect electric circuits. Such connections may be temporary and convenient to plug and unplug, or may be permanent junctions between electrical devices or cables.

As products utilizing connectors, such as the energy storage industry, upgrade, the connectors used have application requirements of over-marshalling (greater than 60). However, due to the increase in the number of connectors, erroneous insertion (including reverse insertion, erroneous insertion, etc. between ferrules, between chassis, and between a ferrule and a chassis) is likely to occur. For example, when the number of connectors to be connected is large, two male terminals and two female terminals that should not be connected may be connected together, which may cause labor waste and increase cost due to the need for reconnection, and even if the connectors and the devices associated therewith may be damaged if they are used without timely finding a wrong insertion, thereby causing a safety hazard.

Hereinafter, an example of the anti-misplug device 110 and the connector assembly 100 for the connector assembly 100 according to the present invention will be described with reference to fig. 1A to 5.

Fig. 1A is a schematic diagram illustrating an assembled state of the connector assembly 100, and fig. 1B is a schematic diagram illustrating an unassembled state of the exemplary connector assembly 100. As shown in fig. 1A and 1B, the connector assembly 100 includes a plug (plug) connector 120, a socket (socket) connector 130, and a mis-insertion prevention device 110. As shown in fig. 1B, the anti-mis-insertion device 110 may include a first anti-mis-insertion portion 111 and a second anti-mis-insertion portion 121, the plug connector 120 may include a first type of ferrule, such as a male-end ferrule 121, and a first housing 122 defining a male-end ferrule installation space 122a, the base connector 130 may include a second type of ferrule, such as a female-end ferrule 131 and a second housing 132 defining a female-end ferrule installation space 132a, and the female-end ferrule 131 may be inserted and mated with the male-end ferrule 121. The connector assembly 100 is assembled by connecting the plug connector 120 and the base connector 130 in the connector assembly 100 shown in fig. 1B (e.g., by mating the male-end ferrule 121 and the female-end ferrule 131), resulting in the state shown in fig. 1A.

It should be noted that fig. 1A and 1B are merely one example of the connector assembly 100. The configuration of the connector assembly 100 and its anti-misplug apparatus 110, plug connector 120, and base connector 130 is not limited to the examples shown in fig. 1A and 1B. For example, the connector assembly 100, the anti-misplug device 110, the plug connector 120, and the receptacle connector 130 may have any other configuration or shape as long as the respective functions (which will be described below) can be achieved. In addition, the types of ferrules contained in the plug connector 120 and the base connector 130 can be interchanged, i.e., the plug connector 120 contains a female-end ferrule and the base connector 130 contains a male-end ferrule mount. Further, the number of ferrules included in each of the plug connector 120 and the base connector 130 is not limited to two in fig. 1A and 1B, and may be any other number, for example, one or three or more. In addition, the plug connector 120 may not only include the male-end ferrule 121, but also include one or more female-end ferrules, and correspondingly, the base connector 130 may not only include the female-end ferrule 131, but also include one or more male-end ferrules. The first anti-mis-insertion portion 113 can be installed into the male-end ferrule installation space 122a of the plug housing 122, and the second anti-mis-insertion portion 114 can be installed into the female-end ferrule installation space 132a of the base housing 132.

Next, referring to fig. 2A to 2C and 3A to 3C, the first erroneous insertion prevention unit 111 and the second erroneous insertion prevention unit 112 of the erroneous insertion prevention device 110 will be described. Wherein fig. 2B is a top view of the plug connector assembly, and fig. 2C is a top view showing the first anti-misinsertion portion in fig. 2B; fig. 3B is a plan view of the cradle connector assembly, and fig. 3C is a plan view showing the second erroneous insertion preventing portion in fig. 3B.

As shown in fig. 2A to 2C, the first anti-misplug portion 111 can be sleeved on the periphery of the male-end ferrule 121 in the plug connector 120 and includes one or more first mating structures 113, and as shown in fig. 3A to 3C, the second anti-misplug portion 112 can be sleeved on the periphery of the female-end ferrule 132 in the base connector 130 and includes one or more second mating structures 114. The one or more second mating structures 114 correspond to the one or more first mating structures 113. For example, as shown in fig. 2A-2C and 3A-3C, the one or more second mating structures 114 are shaped to conform to the one or more first mating structures 113. Alternatively, for example, the one or more second mating structures 114 have a mortise-and-tenon structure, and the one or more first mating structures 113 have a corresponding mortise-and-tenon structure, whereby the one or more second mating structures 114 and the one or more first mating structures 113 can form a mortise-and-tenon fit.

The one or more first mating structures 113 and the one or more second mating structures 114 may be configured to: each of the one or more first mating structures 113 uniquely mates with a corresponding one of the one or more second mating structures 114 when the male-end ferrule 121 mates with the female-end ferrule 131. "uniquely mate" or "uniquely mate" and the like herein may be implemented in a variety of ways. For example, when the male-end ferrule 121 mates with the female-end ferrule 131, the shape of each of the one or more first mating structures 113 uniquely corresponds to the shape of each of the one or more second mating structures 114. For example, the overall outer or inner contour of the one or more first mating structures 113 uniquely corresponds to the overall inner or outer contour of the one or more second mating structures 114 (e.g., the one or more first mating structures 113 collectively form a plug-type overall outer contour that uniquely corresponds to the socket-type overall inner contour of the one or more second mating structures 114 collectively). For example, the shape or size of the plug or receptacle as the one or more first mating structures 113 uniquely corresponds to the shape or size of the receptacle or plug as the one or more second mating structures 114. Thus, unique mating between each male end ferrule 121 and each female end ferrule 131 can be achieved, that is, each male end ferrule 121 (female end ferrule 131) can be mated only with a specific female end ferrule 131 (male end ferrule 121). The specific female-end ferrule 131 (male-end ferrule 121) is not limited to one, and there may be more than one specific female-end ferrule 131 (male-end ferrule 121) as long as the second mating structure 114 (first mating structure 113) sleeved on the female-end ferrule 131 (male-end ferrule 121) can mate with the first mating structure 113 (second mating structure 114) sleeved on the male-end ferrule 121.

For example, the one or more first mating structures 113 can include M (M is a positive integer greater than or equal to 1) first mating structures 113, and the one or more second mating structures 114 can include M second mating structures 114, with the M first mating structures 113 and the M second mating structures 114 distributed at intervals (360/M) ° around the central axis of the male ferrule 121 and the central axis of the female ferrule 131, respectively. As in the example shown in fig. 2A-2C and 3A-3C, M is equal to 4, and the 4 first mating structures 113 and the 4 second mating structures 114 are distributed at 90 ° intervals around the central axis of the male-end ferrule 121 and the central axis of the female-end ferrule 131, respectively. However, without being limited to this example, M may also be equal to 3, 6 or 8, etc., and accordingly, the first mating structures 113 and the second mating structures 114 are distributed at intervals of 120 °, 60 ° or 45 ° around the central axis of the male-end ferrule 121 and the central axis of the female-end ferrule 131, respectively.

The M first mating structures 113 may include N first mating structures 115 and M-N second mating structures 116, and the M second mating structures 114 may include N second mating structures 116 and M-N first mating structures 115, where N is an integer greater than or equal to 0 and less than or equal to M, the first mating structures 115 may be mated with the second mating structures 116, and an arrangement pattern of the first mating structures 115 and the second mating structures 116 included in the first mating structures 113 corresponds to an arrangement pattern of the second mating structures 116 and the first mating structures 115 included in the second mating structures 114.

As a non-limiting example, as shown in fig. 2B, 3B, the 4 first mating structures 113 located at the four corners of the male end ferrule 121 may include 4 first mating structures 115, and the 4 second mating structures 113 located at the four corners of the female end ferrule 131 may include 4 second mating structures 116. In fig. 2B and 3B, the first mating structure 115 is T-shaped with a radially inward end portion, and the second mating structure 116 is T-shaped with a radially outward end portion, in a top view. A cross-section taken along the connection interface after the plug connector 120 and the base connector 130 are connected via the first mating structure 115 and the second mating structure 116 is shown in fig. 4. Fig. 5 shows a cross-sectional view taken along the line B-B in fig. 4, thereby clearly illustrating the structures of the first and second mating structures 115 and 116. By a first pair of mating knotsThe complementary accordion configuration of the formations 115 and 116 prevents the male ferrule 121 from being inserted into the female ferrule 131 if there are two first mating formations 115 or two second mating formations 116 in corresponding positions. Thus, when the male-end ferrule 121 is to be inserted and mated into the female-end ferrule 131, if one or more of the corresponding positions between the first erroneous insertion prevention portions 111 and the second erroneous insertion prevention portions 112 is not one first mating structure 115 corresponding to one first mating structure 116, connection cannot be performed. Thereby, it can be achieved that each of the one or more first mating structures 113 uniquely mates with a respective one of the one or more second mating structures 13. Hereby, for example, by means of the design shown in the figures, it is possible to realize

The cooperation of group's public end, female end lock pin from this usable encoder's interference volume realizes on-the-spot multi-combination demand. It should be noted that what is shown in fig. 2C, fig. 3C, fig. 4, and fig. 5 is merely an example, and actually the same effect may be achieved by other arrangements or designs. For example, the 4 first mating structures 113 may include 3 first mating structures 115 and 1 second mating structure 116, and the 4 second mating structures 113 may include 3 second mating structures 116 and 1 first mating structure 115; the 4 first mating structures 113 may include 2 first mating structures 115 and 2 second mating structures 116, and the 4 second mating structures 113 may include 2 second mating structures 116 and 2 first mating structures 115, and so on. In addition, the arrangement positions and patterns of the first mating structures 115 and the second mating structures 116 may also be different from those shown in fig. 2B and 3B.

Alternatively, the first anti-misinsertion portion 111 may include a first housing mating structure 117, and the first housing mating structure 117 may be formed on an outer sidewall of the first anti-misinsertion portion 111 for uniquely mating with a corresponding mating structure on an inner wall of the male-end ferrule mounting space 122a when the first anti-misinsertion portion 111 is mounted into the male-end ferrule mounting space 122 a. For example, as shown in fig. 2A, 2B, the first anti-misinsertion preventing portion 111 may include 4 first housing mating structures 117, and the shape and arrangement pattern of the 4 first housing mating structures 117 may correspond to the shape and arrangement pattern of corresponding mating structures on the inner wall of the male-end ferrule mounting space 122A to prevent the first anti-misinsertion preventing portion 111 from being erroneously mounted into a non-corresponding male-end ferrule mounting space 122A. It should be noted that fig. 2A and 2B only show one example, the number, shape and arrangement pattern of the first housing matching structures 117 may have other designs, for example, less than 3 or more than 5 first housing matching structures 117 may be provided, for example, the shape may be zigzag, circular, wave-shaped, etc.

Optionally, the second anti-misinsertion portion 112 can include a second housing mating structure 118, and the second housing mating structure 118 can be formed on an outer sidewall of the second anti-misinsertion portion 112 for uniquely mating with a corresponding mating structure on an inner wall of the female-end ferrule mounting space 132a when the second anti-misinsertion portion 112 is mounted into the female-end ferrule mounting space 132 a. For example, as shown in fig. 3A and 3B, the second anti-misinsertion part 112 may include 4 second housing mating structures 118, and the shape and arrangement pattern of the 4 second housing mating structures 118 may correspond to the shape and arrangement pattern of the corresponding mating structures on the inner wall of the female-end ferrule mounting space 132a to prevent the second anti-misinsertion part 112 from being erroneously mounted into the non-corresponding female-end ferrule mounting space 132 a. It should be noted that fig. 3A and 3B only show one example, and the number, shape and arrangement pattern of the second housing matching structures 118 may have other designs, for example, less than 3 or more than 5 second housing matching structures 118, for example, the shape may be zigzag, circular, wavy, etc. Alternatively, the shape and arrangement pattern of the second housing mating structure 118 included in the second anti-misplug portion 112 may correspond to the first housing mating structure 117 included in the first anti-misplug portion 111.

The plug connector 120 may include a plurality of male-end ferrules 121 arranged in an array, and fig. 2A shows only an example of 1 row and 2 male-end ferrules 121, but the plug connector 120 may include any n × m male-end ferrules 121 (n and m are positive integers and may be identical). Correspondingly, the base connector 130 may include female-end ferrules 131 arranged in an array corresponding to the array of male-end ferrules 121 of the plug connector 120, for example, the base connector 130 may include corresponding n × m female-end ferrules 131 (n, m are positive integers and may be identical).

As shown in fig. 2A and 3A, the anti-misinsertion device 110 may further include positive and negative anti-misinsertion mating structures 119, the positive and negative anti-misinsertion mating structures 119 may include a pair of insertion mating structures 119a and 119b, and the pair of insertion mating structures 119a and 119b may be disposed on the side walls, corresponding to the edges, of the pair of first and second anti-misinsertions 111 and 112 corresponding to the pair of male and female ferrules 121 and 131 located at the edges of the array of ferrules. Therefore, the misplug prevention protection can be provided, and the misplug under the condition of the opposite insertion of the insertion core is avoided.

Alternative embodiments of the present application are described in detail above. It will be appreciated that various embodiments and modifications may be made thereto without departing from the broader spirit and scope of the application. Many modifications and variations will be apparent to those of ordinary skill in the art in light of the teachings of this application without undue experimentation.
