Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a connector with a CPA structure. Background Technology

[0002] Connectors are components frequently encountered by electronic engineers. They are used to allow current to flow through blocked or isolated circuits, enabling the circuit to perform its intended function. Because connectors need to be used continuously for extended periods after connection, and may even require relocation, the stability of the connection after connection is receiving increasing attention.

[0003] Connectors typically have two terminals inserted into the male and female end sleeves respectively, securing the two sleeves to achieve electrical connection. To ensure stability after connection and prevent separation, a CPA (Contact Pointer) is usually slidably mounted on one sleeve to secure the other, serving as a secondary locking mechanism for connector positioning. Traditional CPAs are generally installed parallel to the insertion / removal direction, often using a snap-fit / boss structure. Disassembly requires tools, making operation inconvenient, especially for larger connectors where significant force is required.

[0004] Therefore, those skilled in the art urgently need to design a connector with a CPA structure that is simple in structure, easy to install, and highly stable. Utility Model Content

[0005] One objective of this invention is to provide a new technical solution for a connector with a CPA structure.

[0006] According to a first aspect of the present invention, a connector with a CPA structure is provided, comprising a male end sheath, a female end sheath, and a CPA structure;

[0007] The male end sheath and the female end sheath are inserted together in the insertion / removal direction;

[0008] The female end sheath is provided with a first groove, and the male end sheath is provided with a second groove. When the male end sheath and the female end sheath are inserted, the first groove and the second groove are aligned.

[0009] The CPA structure passes sequentially through the first groove and is at least partially inserted into the second groove to form a lock on the male end sheath and the female end sheath in the plugged-in state.

[0010] Optionally, the CPA structure includes a plug-in post and at least one locking protrusion extending radially from the outer wall of the plug-in post.

[0011] Optionally, the inner wall of either the first groove or the second groove is provided with an annular rib, the annular rib being provided with a notch corresponding to each of the locking protrusions, and the locking protrusion passing through the corresponding notch and then rotating the CPA structure to make the locking protrusion abut against the annular rib.

[0012] Optionally, the CPA structure further includes a limiting cap disposed at one end of the insertion post, and a first annular platform is provided on the inner wall of the first groove. When the limiting cap abuts against the first annular platform, the locking protrusion passes through the notch on the annular rib.

[0013] Optionally, the inner wall of the second groove is provided with a second annular platform. When the CPA structure is in the locked state, the locking protrusion is axially restricted between the annular rib and the second annular platform.

[0014] Optionally, the inner wall of the annular rib abuts against the outer wall of the insertion post.

[0015] Optionally, the outer surface of the limiting cap is provided with an operating part, which is configured to facilitate the application of force to drive the CPA structure to rotate.

[0029] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0031] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0032] According to the present disclosure, a connector with a CPA structure 103 is provided, such as Figures 1 to 3 As shown, it includes a male end sheath 101, a female end sheath 102, and a CPA structure 103;

[0033] The male end sheath 101 and the female end sheath 102 are inserted together in the insertion / removal direction;

[0034] The female end sleeve 102 is provided with a first groove 104, and the male end sleeve 101 is provided with a second groove 105. When the male end sleeve 101 and the female end sleeve 102 are inserted, the first groove 104 and the second groove 105 are aligned.

[0035] The CPA structure 103 passes through the first groove 104 and is at least partially inserted into the second groove 105 to form a lock on the male end sheath 101 and the female end sheath 102 in the plugged state.

[0036] CPA structure 103 is inserted into the first groove 104 and the second groove 105 to lock the male end sheath 101 and the female end sheath 102 in the plugged-in state. This allows the operator to quickly lock the male end sheath 101 and the female end sheath 102. Furthermore, this structure allows the operator to manually remove CPA structure 103 without tools to release the lock between the male end sheath 101 and the female end sheath 102.

[0037] In practice, the insertion direction of the CPA structure 103 is perpendicular to the insertion and removal directions of the male end sheath 101 and the female end sheath 102.

[0038] According to one embodiment of a connector with a CPA structure 103 disclosed herein, the CPA structure 103 includes a plug post 106 and at least one locking protrusion 107 extending radially from the outer wall of the plug post 106.

[0039] The male end sheath 101 and the female end sheath 102 are locked by inserting the plug-in pin 106 into the first groove 104 and the second groove 105, and the locking protrusion 107 locks the male end sheath 101 and the female end sheath 102 into a single structure when plugged in.

[0040] Specifically, an annular rib 108 is provided on the inner wall of one of the first groove 104 and the second groove 105. The annular rib 108 is provided with a notch 116 corresponding to each of the locking protrusions 107. After the locking protrusion 107 passes through the corresponding notch 116, the CPA structure 103 is rotated so that the locking protrusion 107 abuts against the annular rib 108.

[0041] The annular rib 108 and the locking protrusion 107 abut against each other, preventing the CPA structure 103 from disengaging from the first groove 104 and the second groove 105, so that the male end sheath 101 and the female end sheath 102 remain locked in the plugged state. The plug post 106 passes through the first groove 104 and is at least partially inserted into the second groove 105 to restrict the male end sheath 101 and the female end sheath 102 from shifting relative to each other in the plugging direction. After the plug post 106 passes through the notch 116 with the locking protrusion 107, the plug post 106 rotates so that the locking protrusion 107 and the annular rib 108 abut against each other, completing the locking between the male end sheath 101 and the female end sheath 102.

[0042] More specifically, the CPA structure 103 also includes a limiting cap 109 disposed at one end of the plug-in post 106, and a first annular platform 110 is provided on the inner wall of the first groove 104. When the limiting cap 109 abuts against the first annular platform 110, the locking protrusion 107 passes through the notch 116 on the annular rib 108.

[0043] The first annular platform 110 abuts against the limiting cap 109 to restrict the downward movement of the CPA structure 103, and the annular rib 108 abuts against the locking protrusion 107 to restrict the upward movement of the CPA structure 103. Through the combined action of the first annular platform 110 and the annular rib 108, the CPA structure 103 is prevented from moving up and down relative to the connector.

[0044] More specifically, the inner wall of the second groove 105 is provided with a second annular platform 111. When the CPA structure 103 is in the locked state, the locking protrusion 107 is axially restricted between the annular rib 108 and the second annular platform 111. This enhances the stability of the CPA structure 103 in the locked state. In a specific implementation, the portion of the insertion post 106 away from the locking protrusion 107 and the portion away from the limiting cap 109 has its outer peripheral wall abutting against the inner peripheral wall of the second annular platform 111, restricting the male end sleeve 101 from shifting relative to the female end sleeve 102 in the insertion / removal direction, so that the male end sleeve 101 does not wobble relative to the female end sleeve 102 in the locked state.

[0045] More specifically, the inner wall of the annular rib 108 abuts against the outer wall of the insertion post 106. This restricts the CPA structure 103 from wobbling in the first groove 104 and the second groove 105, keeping the CPA structure 103 stably assembled on the connector to lock the male end sheath 101 and the female end sheath 102.

[0046] More specifically, the surface of the limiting cap body 109 exposed to the outside is provided with an operating portion 112, and the operating portion 112 is configured to facilitate force application to drive the CPA structure 103 to rotate, so that an operator can unlock or lock the male ferrule 101 and the female ferrule 102 in the mated state by using the CPA structure 103 without tools.

[0047] More specifically, the limiting cap body 109 is provided with a pointing mark 113, and the male ferrule 101 is provided with an unlocking mark 114. When the pointing mark 113 is aligned with the unlocking mark 114, the locking protrusion 107 is aligned with the notch 116 on the annular rib 108, so that the CPA structure 103 is in the unlocking position. Through the pointing mark 113 and the unlocking mark 114, the operator can quickly find the unlocking position to pull out the CPA structure 103, and unlock the locking state of the male ferrule 101 mated with the female ferrule 102.

[0048] The unlocking mark 114 may be represented by the English word "UNLOCK", the Chinese characters for unlocking, or a graphic indicating unlocking.

[0049] More specifically, the male ferrule 101 is further provided with a locking mark 115. When the pointing mark 113 is aligned with the locking mark 115, the locking protrusion 107 abuts against the annular rib 108 so that the CPA structure 103 is in the locking position. Through the pointing mark 113 and the locking mark 115, the operator can quickly find the locking position to realize the locking of the CPA structure 102, so as to achieve locking of the male ferrule 101 mated with the female ferrule 102.

[0050] The locking mark 115 may be represented by the English word "LOCK", the Chinese characters for locking, or a graphic indicating locking.

[0051] Specifically, the number of the locking protrusions 107 is two, and the two locking protrusions 107 are arranged at equal intervals along the circumferential direction of the mating post body 106. In the locked state, the CPA structure 103 is kept stable, preventing the limiting cap body 109 from being at a high position on one side and a low position on the other side, which affects the appearance.

[0052] In specific implementation, the number of the notches 116 provided on the annular rib 108 is also two, for the two locking protrusions 107 to enter, and the CPA structure 103 is rotated to make the locking protrusions 107 abut against the annular rib 108.

[0053] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
