Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more specifically, to a socket connector. Background Art

[0002] A signal mechanism is often required in a high-voltage connector to obtain the connection status, temperature data, etc. of the high-voltage connector. For example, in order to determine whether the plug and the socket are correctly plugged in, a short-circuited interlocking pin is provided in the plug, and an interlocking signal mechanism including an interlocking terminal and a signal cable is provided in the socket. After the plug and the socket are plugged in, the interlocking pin connects the interlocking terminal conductively, thereby connecting the interlocking signal line to send an interlocking signal.

[0003] When the terminals in the socket are row terminals, an isolation plate needs to be set at the end of the socket away from the plug to electrically isolate the tail of the terminal. Since an additional position for setting a signal mechanism needs to be reserved on the socket, a more compact structural layout cannot be designed on the plane perpendicular to the plug-in direction at the end of the socket away from the plug, and it cannot be used in installation occasions with smaller spaces.

[0033] Now, various exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention.

[0034] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present invention or its application or use.

[0035] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification.

[0036] In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0037] As Figure 1-8 shown, an embodiment of the present utility model provides a socket connector that is matingly connected to a plug, including a housing 1 and at least two terminals 2 installed in the housing 1. One end of the terminal 2 away from the plug extends to the outside of the housing 1, and a partition plate 3 is provided between the ends of adjacent terminals 2 extending to the outside of the housing 1. The housing 1 is provided with an installation chamber 12 between adjacent terminals 2, and a signal mechanism 4 is installed in the installation chamber 12. The signal mechanism 4 is electrically connected to a signal cable 5. The partition plate 3 is detachably arranged on the outside of the installation chamber 12, and a wire passing channel 33 for the signal cable 5 to pass through is formed on the partition plate 3. Among them, this embodiment schematically shows three terminals 2 and two partition plates 3. Both of the two partition plates 3 are detachably connected to the housing 1. The housing 1 is provided with the above-mentioned installation chamber 12 between two adjacent terminals 2, and the corresponding partition plate 3 is detachably arranged on the outside of the installation chamber 12.

[0038] It can be understood that in the above solution, the partition plate 3 is detachably installed on the outside of the installation chamber 12, and the signal mechanism 4 is arranged in the installation chamber 12, making full use of the space of the housing 1 corresponding to the partition plate 3. Moreover, a wire passing channel 33 for the signal cable 5 electrically connected to the signal mechanism 4 to pass through is formed on the partition plate 3. Thus, there is no need to reserve the installation positions of the signal mechanism 4 and the signal cable 5 on the end face of the housing 1 away from the plug, and the size of the housing 1 can be further reduced, the structural layout is more compact, and it can adapt to installation occasions with smaller spaces.

[0039] Further, considering the connection requirements, wire passing requirements, and electrical isolation requirements, the partition plate 3 includes a base 31 that is snap-fitted with the housing 1 and a body 32 integrally provided with the base 31. At least one wire passing channel 33 for the signal cable 5 to pass through is formed on the base 31, and the body 32 is used for electrically isolating the terminals 2.

[0040] Further, considering the structural rationality, as well as the convenience and stability of connection with the housing 1, as Figure 5-8 shown, in this embodiment, the base 31 includes an anti-vibration block 311 embedded in the installation chamber 12 (specifically, the first chamber 121 described below), and snap plates 312 symmetrically arranged on opposite sides of the anti-vibration block 311 and snap-fitted with the housing 1. The gap between the anti-vibration block 311 and the snap plates 312 forms the wire passing channel 33. In addition, two opposite sides of the anti-vibration block 311 are in contact with two opposite sides of the installation chamber 12 to achieve the purpose of anti-vibration. In this embodiment, there are two wire passing channels 33 formed on the base 31, and either one can be used when wiring.

[0041] Further, in order to ensure the electrical isolation ability, as Figure 1-2 shown, in this embodiment, one end of the main body 32 of the isolation plate 3 away from the base 31 extends out from the adjacent terminal 2 to the end outside the housing 1 and then continues to extend outward.

[0042] Further, for the convenience of installation, wiring, and layout structure, as Figure 2 shown, in this embodiment, the extending directions of the signal cable 5, the main body 32, and the clamping plate 312 are the same, and the extending directions of the three are the same as the plugging direction of the socket connector.

[0043] Further, in order to enable the socket connector to be installed smoothly and prevent the clamping plate 312 from protruding from the outer wall of the housing 1, and also to achieve the clamping fit between the clamping plate 312 and the housing 1, as Figure 2 、 3 shown, in this embodiment, a receiving groove 11 for receiving the clamping plate 312 is recessed inward on the outer wall of the housing 1. A snap structure is provided between the clamping plate 312 and the bottom wall of the receiving groove 11. The snap structure of this embodiment includes a boss 111 on the bottom wall of the receiving groove 11 and a slot 314 on the clamping plate 312. The clamping plate 312 and the receiving groove 11 are clamped through the snap structure to achieve the detachable connection between the isolation plate 3 and the housing 1.

[0044] In other embodiments, the isolation plate and the housing can also be connected by other detachable methods. For example, the clamping plate of the isolation plate can be connected to the housing by conventional connection methods such as riveting, bonding, and interference fitting.

[0045] Further, in order to further stabilize the isolation plate 3 after the isolation plate 3 is installed, and enable the clamping plate 312 to effectively and reliably carry the main body 32, as Figure 2 、 5 、7, and 8 shown, in this embodiment, one end of the clamping plate 312 away from the plug extends inward to form a lapping portion 313 for carrying the main body 32. The housing 1 is provided with a lapping groove 112 for receiving the lapping portion 313 at the entrance of the receiving groove 11. After the clamping plate 312 is inserted into the receiving groove 11, the lapping portion 313 is received in the lapping groove 112, and the end face of the lapping portion 313 away from the plug is flush with the end face of the housing 1 away from the plug to prevent the lapping portion 313 from affecting the neatness of the external structure of the housing 1.

[0046] Further, based on the design requirements of the connector, the above terminal 2 is a row terminal, as Figure 2As shown, in this embodiment, based on connection needs, one end of the terminal 2 away from the plug is at least partially bent in the direction of the main body 32, and a receiving groove 321 for accommodating the bent portion of the terminal 2 is provided on the end surface of the main body 32 facing the terminal 2. The cooperation between the receiving groove 321 and the bent portion of the terminal 2 also enables the isolation plate 3 to obtain a more stable installation effect with the help of the terminal 2.

[0047] Furthermore, based on the interlocking requirements of high voltage connectors, such as Figure 6 , 7 As shown, in this embodiment, the signal mechanism 4 is an interlocking terminal 2, and the installation chamber 12 includes a first chamber 121 for installing the interlocking terminal 2 and a second chamber 122 located at an end of the first chamber 121 away from the plug. The signal cable 5 is bent and passes through the second chamber 122 and then led out from one of the two line-dropping channels 33 mentioned above.

[0048] In other embodiments, the signal mechanism may also be a temperature sensor to monitor the temperature inside the socket connector, or the signal mechanism may also include an interlocking terminal and a temperature sensor. In short, the signal mechanism may be set as needed according to actual conditions and prior art.

[0049] During specific assembly, the terminal 2 can be assembled into the base body 1 first, and then the interlocking terminal 2 connected to the signal cable 5 can be installed into the installation chamber 12, and finally the isolation plate 3 can be installed on the base body 1. At this time, the main body 32 of the isolation plate 3 isolates the adjacent terminals 2, and the signal cable 5 is thrown out from the wire throwing channel 33. After other related auxiliary structures such as the shielding shell are also installed in place, the socket connector can be installed and used.

[0050] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
