Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The invention also provides an electric connector structure, as shown in fig. 1 and fig. 2, which comprises a wire holder 1, wire clamps 2, an operating piece 3 and plug pins 4, wherein the number of the plug pins 4 is equal to that of the wire clamps 2, and the plug pins and the wire clamps are in one-to-one correspondence conduction connection.

The wire clamp 2 has two states of a loosening state and a clamping state, and acts on the connected cable in the clamping state so that the connected cable is fixed on the wire holder 1; the operating piece 3 is provided with an operating structure exposed out of the wire holder 1 and can be switched between a first position and a second position relative to the wire holder 1; when the cable clamp 2 is in the first position, the cable clamp 2 is in a loosening state, and the state is shown in figure 2; in its second position, the clamp 2 is in a clamped state, which is shown in fig. 1.

As shown in fig. 3, the operating member 3 is rotatably mounted with respect to the wire holder 1, and has a profile 31, a handle portion 32 and a hinge pillar 34, and the operating member 3 is hinged to the wire holder 1 through the hinge pillar 34; a handle portion 32, i.e., the above-described exposed manipulating structure; as the operating member 31 is rotated relative to the wire holder 1, different positions of the profile 31 are applied to the wire clamp 2, and the distance between the position of the profile 31 applied to the wire clamp 2 and the center of rotation of the operating member 3 is varied, so that the profile 31 exerts a pressing action on the wire clamp 2 to deform the wire clamp 2 when the operating member 3 is rotated. In this embodiment, the profile 31 is a continuous cam profile.

In particular, the clip 2 is an annular closing element formed by bending an elastic sheet; one end of the elastic sheet is formed with a wiring hole 21, the other end is an embedded end 22, and the embedded end 22 is embedded in the wiring hole 21 and can slide in the wiring hole 21. In this embodiment, when the wire clip 2 is in the clamping state, as shown in fig. 4, it is in the weak interference or no interference state, that is, the pressing force of other components (including the wire holder 1 and the operating member 3) is small, and at this time, the embedded end 22 is located at the first end of the wire connecting hole 21, and the elastic force of the wire clip 2 itself will be clamped by the wire connecting cable; when the wire clamp 2 is in a loose state, as shown in fig. 5, the operating member 3 has a strong interference effect on the wire clamp 2, so that the wire clamp 2 is greatly deformed, the embedded end 22 is forced to leave the first end of the wiring hole 21, a gap is formed between the embedded end 22 and the first end, a user can stretch the end of a connected cable into the gap and rotate the operating member 3 to the second position to complete wiring operation, and after wiring is completed, the state is as shown in fig. 6, and the operating member 3 is operated without tools, so that the operation is convenient and fast.

Preferably, the wire holder 1 and the handle portion 32 are fixed to each other by a snap-fit structure, so that the operating member 3 is maintained at the second position, and when the operating member 3 is at the first position, the operating member 3 is maintained at the first position by the backward pressing force of the wire clamp 2. As shown in fig. 7, the wire holder 1 has a fitting groove 14 into which the handle portion 32 is fitted, and the engagement structure includes groove portions 33 formed on both sides of the handle portion 32 and projections 15 formed on both side walls of the fitting groove 14. When the handle portion 32 is pushed by the user to be fitted into the fitting groove 14, the projecting portion 15 enters the groove portion 33 to block the handle portion 32 from rotating in the reverse direction (as shown in fig. 8), and the projecting portion 15 and the groove portion 33 are disengaged from each other only when the handle portion 32 is subjected to a large reverse force.

The plug pins 4 are used for connecting other electrical connectors to realize mutual conduction of cables connected by the two electrical connectors. The plug pins 4 may be male plug pins and female plug pins, the male plug pins are cylindrical, the female plug pins are cylindrical, and the plug pins included in the two mutually opposite-plugged electrical connectors are the male plug pins and the female plug pins respectively, so that when the two are opposite-plugged, the male plug pins and the female plug pins can be oppositely plugged one by one to be conducted.

In the electrical connector shown in fig. 1, namely, the electrical connector includes 6 sets of the above-mentioned fast wiring structures, and the 6 sets of fast wiring structures form a square array of 2 × 3, in a specific use, for this type of electrical connector, there may be a plurality of situations where a plurality of wire clamps 2 are connected to the same power supply or signal, and for this situation, if these wire clamps 2 are connected to the same power supply or signal by cables respectively, it is obvious that the circuit is not indirect, and wastes wires, and the operation efficiency is low. In order to solve the above problem, the electrical connector structure further includes a jumper 5 that can be detached from or attached to the wire holder 1 as needed, the jumper 5 includes a plurality of jumper pins 51 that are in conduction with each other, and when the jumper 5 is attached to the wire holder 1, each jumper pin 51 is in conduction with one of the plug pins 4, so that all the wire clamps 2 connected to the jumper pins 51 of the same jumper 5 are in conduction with each other, and the cables connected to any one of the wire clamps 2 can be in conduction with all the wire clamps 2. The jumper 5 has two forms, as shown in fig. 9, a transverse jumper which can realize the conduction connection of two wire clamps 2 in a transverse row, and the state of being installed on the wire holder 1 is shown in fig. 10; fig. 11 shows a longitudinal jumper which can realize the conduction connection of three vertical-row wire clamps 2, and the installation state of the jumper on a wire holder 1 is shown in fig. 1.

Preferably, each clip 2 is connected with the corresponding plug-in pin 4 through a pin seat 6; the whole outline of the needle seat 6 is concave and is in a shape with an opening at the upper part, and the shape is preferably U-shaped or V-shaped; and it is preferably formed by integrally molding a single metal sheet, and one side of it is provided with an access end 62, and the access end 62 is embedded in the wiring hole 21 of the wire clip 2; the end of the connected cable is pressed on the access end 62 by the elastic restoring force of the wire clamp 2 to realize the conduction between the end of the cable and the access end 62. The other side of the hub 6 is formed with a notch 61 into which the end of the straddle pin 51 fits, as shown in fig. 12. And further, in order to ensure the firmness after the engagement between the bridging needle 51 and the notch 61, two sides of the mouth of the notch 61 are provided with first dead points 63, and two sides of the head of the bridging needle 51 are provided with second dead points 52; as shown in fig. 13, after the end of the jumper pin 51 is inserted into the notch 61, the second pause point 52 is closer to the bottom of the notch 61 than the first pause point 63, so that the first pause point 63 can prevent the end of the jumper pin 51 from being pulled out of the notch 61, and the jumper 5 can be prevented from falling off accidentally, and the end of the jumper pin 51 can be separated from the notch 61 only when the jumper 5 is subjected to a large pulling force. In this embodiment, the needle holder 6 is compact, and since the end of the connected cable is pressed against the access end 62 of the needle holder 6 by the elastic restoring force of the wire clamp 2, the notch 61 and the access end 62 are formed on two sides of the same concave metal sheet, which is beneficial to the compactness of the whole structure of the electric connector.

Preferably, the wire clamps 2 are made of metal and have conductivity, and the wire holder 1 is formed with probe holes 13 leading to each wire clamp 2, so that after wire connection, if a user checks whether each wire is conducted with the wire clamp 2, the end of the probe can be contacted with the wire clamp 2 by inserting the end of the probe into the probe hole 13 (as shown in fig. 2), and whether the equipment connected with the probe indicates that the wire connection is successful is judged.

Further, the wire holder 1 includes two parts, namely a holder body 11 and a cover body 12, which are fixed to each other through a fastening structure, the probe hole 13 is disposed on the cover body 12, and the cover body 1 is further provided with a wire feeding hole 16 for the end of the cable to enter and a pin hole 17 for the cross-over pin 51 to pass through. Specifically, as shown in fig. 14, the fastening structure includes a boss portion 111 disposed on the seat body 11 and a bayonet portion 121 disposed on the cover 12, and after the seat body 11 is fastened to the cover 12, the boss portion 111 is disposed in the bayonet portion 121, so that the seat body 11 and the cover 12 cannot be disengaged.

The invention also provides an electrical connector assembly, as shown in fig. 15, which includes two sets of the above electrical connector structures, the structural compositions of the two sets of electrical connector structures are completely the same, but in order to realize the combined use of the two, the specific structures of part of the two parts are different, and mainly appear as follows: the plug pins 4 in the two groups of electric connector structures are respectively a male plug pin and a female plug pin, partial structures of two wire holders 1 of the other two groups of electric connector structures are different, the holder bodies 11 of the two wire holders 1 are respectively a male holder body 11-1 and a female holder body 11-2, the male holder body 11-1 is provided with a plug boss 11-10, the female holder body 11-2 is provided with a plug groove 11-20, the two groups of electric connector structures can be mutually connected in an opposite plug manner, so that the male plug pins 41 on the two groups of electric connector structures are correspondingly connected with the female plug pins 42 of the female plug pins one by one, and the plug bosses 11-10 are embedded into the plug grooves 11-20.
