Description

TECHNICAL FIELD

[0001] The utility model relates to a connector and a connector assembly with the same. BACKGROUND

[0002] To achieve electrical connection between different electronic devices, various forms of electrical connectors exist. Electrical connectors can be distinguished by the location in which they are disposed, such as line end connectors and board end connectors. Line end connectors are located at one end of a cable and are used to mate with board end connectors, while board end connectors are disposed on a circuit board. With the continuous progress and constant innovation of various types of electronic products, the performance of new electronic products has been greatly improved, and the types of electrical signals tend to be more diverse and require more bandwidth.

[0003] If a line end connector cannot be properly mated when it is inserted into a board end connector, it may result in transmission failure, or even damage to the device. In addition, multiple modules are generally provided in a communication cabinet, so multiple cooling fan modules may be provided in the cabinet. However, when these fan modules are in operation, the vibrations generated may cause the surrounding connectors to slide, resulting in unstable signal transmission and power supply, and other problems. SUMMARY

[0004] According to some embodiments of the utility model, a connector includes an insulating body and a cable. The insulating body has a downward socket configured to mate with a counterpart connector. The front side of the insulating body includes at least one limiting tongue. The limiting tongue has two downward extensions and a groove between the two extensions. The opening direction of the groove is downward, configured to engage the protrusion of the counterpart connector to position it. The cable extends from the rear side of the insulating body, and the length direction of the cable is perpendicular to the opening direction of the groove.

[0005] In some embodiments, the two extensions of the limiting tongue protrude downward to define the groove.

[0006] In some embodiments, the limiting tongue is in the shape of an inverted U.

[0007] In some embodiments, there is a gap between the two extensions of the limiting tongue and the surface of the front side of the insulating body.

[0008] In some embodiments, the connector further includes a circuit board. The circuit board is located in the socket of the insulating body. The opening direction of the groove of the limiting tongue is perpendicular to the length direction of the circuit board.

[0009] In some embodiments, the connector further includes a pull strap. The pull strap is connected to the front side of the insulating body and extends above the top surface of the insulating body. The length direction of the pull strap is perpendicular to the opening direction of the groove.

[0010] In some embodiments, the front side of the aforementioned insulating body includes two limiting tongues, with one end of the pull strap located between the two limiting tongues.

[0011] In some embodiments, the connector further includes a connecting member. The connecting member is fixed to the front side of the insulating body and connects to one end of the pull strap. The connecting member has protrusions configured to couple to the through holes of the mating connector.

[0012] According to some embodiments of the present invention, a connector assembly includes a connector and a mating connector. The connector includes an insulating body and a cable. The insulating body has a downward-facing insertion port. The front side of the insulating body includes at least one limiting tongue. The limiting tongue has two downward extensions and a groove located between these two extensions. The opening direction of the groove is downward. The cable extends from the rear side of the insulating body, and the length direction of the cable is perpendicular to the opening direction of the groove. The mating connector is configured to mate with the connector. The mating connector has a protrusion configured to engage with the groove of the limiting tongue to position the connector.

[0013] In some embodiments, the inner edge of the groove of the aforementioned limiting tongue directly contacts the protrusion of the mating connector.

[0014] In the above embodiments of this utility model, since the connector has a limiting tongue on its front side, and the limiting tongue has two downward extensions and a groove between the two extensions, when the connector mates with a mating connector, the groove of the limiting tongue of the connector can engage with the protrusion of the mating connector, positioning the connector on the mating connector. This connector can solve the problem of preventing shaking and mating misalignment under limited space conditions by using the limiting tongue. In this way, the connector can avoid slippage due to vibration, thereby providing stable signal transmission and power supply. In addition, the limiting tongue can be formed together with the insulating body during manufacturing, making it compatible with existing products and providing excellent anti-skewing capability.

[0022] Figure 1 Fig. 1 is a perspective view of a connector according to an embodiment of the present application. As shown in the figure, the connector 100 includes an insulating body 110 and a cable 130. In this embodiment, the connector 100 is a wire end connector, which can be mated with a mating connector, such as a board end connector. In addition, the connector 100 is a right angle connector, and the insulating body 110 has a downward facing socket O, which can be mated with the mating connector. The front side 111 of the insulating body 110 includes at least one limiting tongue 120. The limiting tongue 120 has two downward extending portions 122 and a groove 124, and the groove 124 is located between the two extending portions 122. That is, the two extending portions 122 of the limiting tongue 120 protrude downward to define the groove 124. The limiting tongue 120 is in the shape of an inverted U. The opening direction (e.g., direction Z) of the groove 124 of the limiting tongue 120 faces downward, which can be used to engage a protrusion (to be described) of the mating connector to securely position the connector 100 on the mating connector. The cable 130 extends from the rear side 113 of the insulating body 110, and the length direction (e.g., direction X) of the cable 130 is perpendicular to the opening direction of the groove 124 of the limiting tongue 120. Figure 4 Fig. 2 is a front view of the connector of Fig. 1 mated with a mating connector.

[0023] In some embodiments, the limiting tongue 120 has the same material as the insulating body 110, such as plastic. The limiting tongue 120 may be formed together with the insulating body 110 during manufacturing, so that the limiting tongue 120 and the insulating body 110 are integrally molded plastic parts.

[0024] Figure 2 For illustration Figure 1 The connector 100 is shown in the bottom view. A gap G exists between the two extensions 122 of the limiting tongue 120 and the surface of the front side 111 of the insulating body 110. The gap G allows the metal shell of the mating connector to be inserted (into the...). Figure 4 describe).

[0025] See also Figure 1 and Figure 2 The connector 100 also includes a circuit board 160. The circuit board 160 is located in the socket O of the insulating body 110 and is electrically connected to the cable 130. The opening direction (e.g., direction Z) of the groove 124 of the limiting tongue 120 is perpendicular to the length direction (e.g., direction Y) of the circuit board 160.

[0026] In addition, connector 100 also includes a pull strap 140. The pull strap 140 connects to the front side 111 of insulating body 110 and extends above the top surface of insulating body 110, for example, extending in direction X. The length direction of pull strap 140 (e.g., direction X) is perpendicular to the opening direction (e.g., direction Z) of the groove 124 of limiting tongue 120. In this embodiment, the front side 111 of insulating body 110 includes two limiting tongues 120, and one end of pull strap 140 is located between the two limiting tongues 120.

[0027] In this embodiment, the connector 100 may further include a connector 150. The connector 150 may be embedded and fixed to the front side 111 of the insulating body 110, and the connector 150 connects to one end of the pull strap 140. Furthermore, the connector 150 has a protrusion 152, which can be used to couple to the through hole of the mating connector (to be...). Figure 4 describe).

[0028] It should be understood that the component connections, materials, and functions already described will not be repeated, but will be stated in the preceding text. The following description will explain the state of the aforementioned connector 100 when it is mated with the mating connector.

[0029] Figure 3 For illustration Figure 1 Front view of connector 100 before mating with connector 300. Figure 4 For illustration Figure 1 The front view of connector 100 after mating with connector 300. See also... Figure 3 and Figure 4The connector assembly 200 includes the mating connector 300 and the aforementioned connector 100. The mating connector 300 is mateable with the connector 100. In the present embodiment, the mating connector 300 is a board end connector. The mating connector 300 includes a housing 310 and a circuit board 320. The housing 310 is located on the circuit board 320. The housing 310 of the mating connector 300 has a protrusion 312 and a through hole 314. For the convenience of description, Figure 3 The protrusion 312 of the housing 310 of the mating connector 300 is represented by a diagonal line area, which protrudes outwardly from the housing 310. Figure 4

[0030] In the assembly, the connector 100 can be moved in the direction D to mate with the mating connector 300. When the connector 100 mates with the mating connector 300, the groove 124 of the limiting tongue 120 of the connector 100 can engage the protrusion 312 of the mating connector 300, so that the connector 100 can be positioned on the mating connector 300. The inner edge of the groove 124 of the limiting tongue 120 can directly contact the protrusion 312 of the mating connector 300, so that the left side, the upper side and the right side of the protrusion 312 are surrounded by the limiting tongue 120. In the present embodiment, the two extending portions 122 of the limiting tongue 120 abut the left side and the right side of the protrusion 312 respectively, which can effectively limit the direction Y.

[0031] In the state that the connector 100 mates with the mating connector 300, the housing 310 of the mating connector 300 is at least partially embedded in the gap G (see Figure 2 ) between the limiting tongue 120 and the front side 111 of the insulating body 110, which can effectively limit the direction X (see Figure 1 ). In addition, the protrusion 152 of the connecting piece 150 of the connector 100 can also couple the through hole 314 of the mating connector 300, which can provide the user with a positioning feeling and further improve the positioning effect of the connector 100.

[0032] The connector assembly 200 with the connector 100 can be applied to a server. When the fan module in the server generates vibration, the connector 100 can still be stably positioned on the mating connector 300 without sliding.

[0033] ​In summary, since the front side 111 of the connector 100 has the limiting tongue 120, and the limiting tongue 120 has two downward extending portions 122 and a groove 124 between the two extending portions 122, when the connector 100 is mated with the mating connector 300, the groove 124 of the limiting tongue 120 of the connector 100 can engage the protrusion 312 of the mating connector 300, so as to position the connector 100 on the mating connector 300. This connector 100 can solve the problems of preventing shaking and deviation from mating by using the limiting tongue 120 under the condition of limited space. In this way, the connector 100 can avoid sliding due to vibration, thereby providing stable signal transmission and power supply. In addition, the limiting tongue 120 can be formed together when manufacturing the insulating body 110, which is compatible with the original product and has excellent anti-deviation ability.
