Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connections, and in particular to a connector for quick identification of ejected PINs. Background Technology
[0002] Connectors are crucial components of new energy equipment, typically consisting of a connector plug and a connector socket. During mating, abnormal mating can cause the terminal pins to come loose, leading to poor terminal contact. Currently, connectors cannot directly identify terminal pin loosening but rather indirectly detect it, such as through partial limiting structures or abnormal distances of the lead wires at the tail. The drawback is that if the lead wires are abnormal, the current structure's recognition response speed is slow and cannot detect it in time, and there is a probability that it cannot be identified at all, which can lead to poor terminal contact, easily causing abnormal problems such as high temperatures, and ultimately resulting in significant economic losses. Utility Model Content
[0003] To address one or more of the aforementioned problems, this invention provides a connector for quickly identifying ejected PINs.
[0004] According to one aspect of the present invention, a connector for quick identification of PIN ejection includes a housing and a plurality of power terminals sleeved within the housing, and also includes a plurality of PIN ejection identification parts;
[0005] The PIN ejection identification unit includes a limiting sleeve, an integrated injection-molded identification ring connected inside the limiting sleeve, two signal detection components, and two lead wires;
[0006] The ring sleeve of the limiting sleeve is inserted into the power tube hole of the housing and its inner hole is sleeved to the power insertion part. The rear end of the power terminal is inserted into the power insertion part and its positioning end plate is attached to the limiting end plate at the front end of the sleeve.
[0007] The identification ring is located inside the limiting end plate and its two ends are electrically connected to the front end of the lead wire; the inner ends of the two signal detection devices are electrically connected to the rear end of the two lead wires and their outer ends are electrically connected to the control unit; when an abnormal insertion occurs beyond the limit, the positioning end plate can be cracked, causing the identification ring to break or the connection between the identification ring and the lead wire to break. The signal detection device quickly detects the PIN withdrawal and provides feedback.
[0008] In some embodiments, the front end of the sleeve is integrally formed into a circular limiting end plate, and the identification ring is vertically positioned and concentrically located on the limiting end plate; the identification ring is close to the edge of the central hole of the limiting end plate.
[0009] In some implementations, the identification ring is a conductive wire or a conductive sheet.
[0010] In some embodiments, the annular positioning shoulder in the middle of the sleeve fits against the positioning surface of the power tube hole, and the anti-rotation lug on the front wall of the positioning shoulder enters the anti-rotation groove of the power tube hole; the inner end of the signal detection element is axially located on the positioning shoulder and a connected anti-rotation lug.
[0011] In some embodiments, the lead wire includes a vertically connected longitudinal wire and a transverse wire. The front end of the longitudinal wire is bent at a right angle to form a transverse end, and the rear end of the transverse wire is bent at a right angle to form a longitudinal end. The longitudinal wire is integrally injection molded to connect to a sleeve. The transverse wire and the longitudinal end are integrally injection molded to connect to an anti-rotation lug. The transverse end is integrally injection molded to connect to a limiting end plate and is electrically connected to both ends of an identification ring. The longitudinal end is electrically connected to the front end of a signal detection component.
[0012] In some implementations, the vertical clearance groove at the rear end of the sleeve accommodates two axial signal detection elements.
[0013] In some embodiments, the signal output line connected to the outer end of the signal detection element passes sequentially through the longitudinal through-hole of the housing, the longitudinal through-hole of the sealing block, and the arc-shaped through-hole of the tail cover.
[0014] In some embodiments, the PIN ejection identification part further includes a metal toothed sleeve, which is interference-connected to the anti-reverse groove on the rear side of the limiting sleeve and has its inner spring piece abutting against the anti-reverse shoulder of the power socket component.
[0015] In some embodiments, a crown spring is interference-fitted into the annular groove of the power socket, and the crown spring is interference-fitted into the rear end of the power terminal.
[0016] In some implementations, the connector is a battery swapping connector, and the connector housing has two power terminals and two PIN ejection identification parts symmetrically arranged inside.
[0017] This connector features a novel PIN ejection identification section with a rapid PIN ejection detection mechanism. Under normal conditions, the PIN ejection identification section is connected and has a signal. When the PIN is ejected and excessive external force is applied, the PIN ejection identification section breaks, thus disconnecting the signal. This allows for direct and rapid identification of abnormal PIN ejection. Its advantages are: First, the structure has a fast response speed, enabling instantaneous identification of abnormal PIN ejection. The identification speed is fast and the reliability is high, facilitating repair and ensuring safe connector use. This reduces the risk of abnormal connector use, avoids problems such as high temperatures caused by poor terminal contact, and minimizes losses. Second, the integrated structure of the PIN ejection identification section results in a small overall size and simple structure, facilitating production and assembly. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, while the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.
[0027] Figures 1 to 5 A connector for quick PIN ejection identification according to one embodiment of the present invention is schematically shown. As shown, the connector for quick PIN ejection identification includes a housing 01 and a plurality of power terminals 02 sleeved within the housing 01, and also includes a plurality of PIN ejection identification parts 00;
[0028] The PIN rejection identification unit 00 includes a limiting sleeve 1 and an identification ring 2 integrally injection molded and connected inside the limiting sleeve 1, two signal detection components 3, and two lead wires 4;
[0029] The annular sleeve 10 of the limiting sleeve 1 is inserted into the power tube hole 010 of the housing 01 and its inner hole is sleeved to the power insertion part 011. The rear end of the power terminal 02 is inserted into the power insertion part 011 and its positioning end plate 021 is attached to the limiting end plate 11 at the front end of the sleeve 10.
[0030] The identification ring 2 is located inside the limiting end plate 11 and its two ends are electrically connected to the front end of the connecting wire 4. The identification ring 2 is preferably a conductive wire or a conductive sheet.
[0031] The inner ends of the two signal detection components 3 are electrically connected to the rear ends of the two lead wires 4, and their outer ends are electrically connected to the control unit. When an abnormal insertion occurs beyond the limit, the limiting end plate 11 can crack the positioning end plate 021, and cause the identification ring 2 to break or the connection between the identification ring 2 and the lead wire 4 to break. The signal detection component 3 quickly detects the PIN withdrawal and provides feedback.
[0032] The connector is preferably a battery swapping connector. The connector housing 01 is symmetrically provided with two power terminals 02 and two opposing pin rejection identification parts 00. The connector housing 01 is also equipped with a signal module and a PE grounding module.
[0033] This connector features a novel pin ejection identification section 00 for rapid pin ejection identification. In normal operation, the pin ejection identification section is connected and has a signal. When the pin is ejected and excessive external force is applied, the pin ejection identification section breaks, thus disconnecting the signal. This allows for direct and rapid identification of abnormal pin ejection. The advantages are: First, this structure has a fast response speed, enabling instantaneous identification of abnormal pin ejection. The identification speed is fast and reliable, facilitating repair and ensuring safe connector use. It reduces the risk of abnormal connector use, avoids problems such as high temperatures caused by poor terminal contact, and minimizes losses. Second, the integrated pin ejection identification section 00 has a small overall size and simple structure, facilitating production and assembly.
[0034] Preferably, the front end of the sleeve 10 is integrally formed into a circular limiting end plate 11, and the identification ring 2 is vertically positioned and concentrically located on the limiting end plate 11.
[0035] The identification ring 2 is located near the edge of the center hole of the limiting end plate 11. Its advantage is that this arrangement further ensures that the limiting end plate 11 and the identification ring 2 break synchronously, improving the reliability of the identification PIN removal.
[0036] Furthermore, a circular positioning shoulder 12 is formed in the middle of the sleeve 10. Several anti-rotation lugs 13 are arranged circumferentially on the front wall of the positioning shoulder 12. The positioning shoulder 12 fits against the positioning surface of the power tube hole 010, and the anti-rotation lugs 13 enter the anti-rotation groove of the power tube hole 010. The inner ends of the two signal detection elements 3 are axially positioned within the positioning shoulder 12 and a connected anti-rotation lug 13. The advantages are: this structure facilitates installation and positioning, and results in high product accuracy.
[0037] Furthermore, the lead wire 4 includes a vertically connected longitudinal wire 40 and a transverse wire 41. The front end of the longitudinal wire 40 is bent at a right angle to form a transverse end 42, and the rear end of the transverse wire 41 is bent at a right angle to form a longitudinal end 43. The longitudinal wire 40 is integrally injection molded to connect to a sleeve 10. The transverse wire 41 and the longitudinal end 43 are integrally injection molded to connect to an anti-rotation lug 13. The transverse end 42 is integrally injection molded to connect to a limiting end plate 11 and is electrically connected to both ends of the identification ring 2. The longitudinal end 43 is electrically connected to the front end of the signal detection component 3. Its advantages are: this arrangement facilitates the layout of various components and is suitable for more product structures.
[0038] Furthermore, the vertical clearance groove 16 at the rear end of the sleeve 10 accommodates two axial signal detection elements 3. Preferably, the rear end of the housing 01 has two opposing longitudinal through-holes for the signal detection elements 3, the sealing block has two opposing longitudinal through-holes, and the tail cover 013 has an arc-shaped through-hole. The signal output lines connected to the outer ends of the signal detection elements 3 pass through the longitudinal through-holes, longitudinal through-holes, and arc-shaped through-holes in sequence. The beneficial effect is that the clearance groove 16 and each through-hole are formed directly on the original components, which can reduce the size of the equipment.
[0039] Furthermore, the PIN ejection identification unit 00 also includes a metal toothed sleeve 5. A large-diameter anti-rejection groove 14 is provided on the rear side of the central hole 15 of the limiting sleeve 1, and the metal toothed sleeve 5 is interference-fitted into the anti-rejection groove 14. The metal toothed sleeve 5 has a circumferential array of feeding springs, and each feeding spring has an inwardly bent inner spring piece 51. The front end of each inner spring piece 51 abuts against the anti-rejection shoulder 012 of the power socket component 011. Its beneficial effect is that this arrangement has a good anti-rejection effect, reducing the probability of PIN ejection.
[0040] Furthermore, anti-rotation bosses 17 are symmetrically provided inside the central hole 15; the power socket component 011 is provided with an anti-rotation cut surface, and the anti-rotation bosses 17 are fitted and connected to the anti-rotation cut surface.
[0041] A crown spring 6 is interference-fitted into the annular groove of the power socket 011, and the crown spring 6 is interference-fitted into the rear end of the power terminal 02. The beneficial effect is that this arrangement can securely fix the power socket 011, reducing the likelihood of pin slippage.
[0042] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
