technical field

The utility model relates to a crystal head and a network cable pliers.

Background technique

The crystal head is a connector used to connect the electronic wiring cable to the network, and is mainly used for signal connection. The existing crystal head includes a plastic shell, and the front end is provided with eight wire slots, and the wire slots are provided with electrical terminals arranged side by side. Each electrical terminal corresponds to one first, and then the network cable clamp is used. Insert the line cores of the network cable into the corresponding slots, put them into the crimping port of the network cable pliers, and then press down the corresponding electric terminal with the pressure bar in the crimping port, so that the electric terminal is connected with the wire , for signal transmission.

When building a new weak current system or troubleshooting the system, it is often necessary to measure whether the network cable is normal. The existing method is that an engineer installs one end of the line measuring instrument at one end of the network cable, and another engineer plugs in the other end of the line measuring instrument at the other end of the network cable for inspection. If the inspection result is that the network cable is abnormal, it is often suspected that the crystal head is faulty, and the crystal head needs to be remade; when remaking the crystal head, there will be a problem, which point of the crystal head should be remade? In general, first make the crystal head that is closer to the engineer, and if the network cable does not return to normal, then make another point.

The above network cable measurement and crystal head production have affected the work efficiency on site. Especially when there are few workers and the distance between the two ends of the network cable is long, the work efficiency is very low.

Utility model content

The purpose of the utility model is to provide a crystal head and a network cable pliers, which can effectively solve the problems that the existing network cable production and crystal head measurement are carried out separately, making troubleshooting difficult and low work efficiency.

In order to solve the above-mentioned technical problems, the utility model is realized through the following technical solutions: a crystal head, including a casing, the front end of the casing is provided with a wire slot, and the wire slot is provided with eight electrical terminals arranged side by side. The terminals all include two mutually insulated contact strips, and the two contact strips are arranged front and rear and located on the same straight line.

Preferably, eight sub-slots are provided in the wire slot, and a piece of electric terminal is provided in each sub-slot; the eight sub-slots correspond to eight sub-lines in a network cable, so that each sub-line can be accurately connected with Corresponding electrical terminal contacts.

Preferably, there is a gap or an insulating spacer between the two contact pieces of the same electric terminal; leaving a gap between the two contact pieces can effectively reduce the manufacturing cost, and between the two contact pieces Installing insulating spacers between them can stabilize the position between the two contact pieces while ensuring insulation.

A network cable pliers, including a pliers body and a crimping port, the crimping port is provided with a bead corresponding to the electric terminal of the crystal head, each bead includes two conductive pressing pieces, and each pressing piece is connected to a The two pressing pieces are insulated from each other. The pliers body is provided with a power supply and LED lights. The number of LED lights is equal to the number of beading bars. Each LED light is connected in series with the power supply and the corresponding bedding bar.

Preferably, there is a gap or an insulating spacer between the two pressing pieces; leaving a gap between the two pressing pieces can effectively reduce manufacturing costs, and setting an insulating spacer between the two pressing pieces can ensure insulation While stabilizing the position between the two contact pieces.

Preferably, a positioning stopper for the crystal head is provided in the crimping port; positioning is performed when the crystal head is inserted into the crimping port, so as to ensure the one-to-one correspondence between the connecting piece and the pressing piece.

Compared with the prior art, the utility model has the advantages that: this proposal improves the electric terminal of the crystal head, changes the original electric terminal into two electric plates, and improves the network cable pliers at the same time, increasing In addition to the monitored power supply and LED lights, the pressure strips of the network cable pliers are also changed to two conductive pressure pieces, so that as long as the two power strips can be in contact with a branch line at the same time during crimping, the LED light will light up. The detection of the crystal head is completed at the same time as the crystal head is connected. If there is a problem, you can directly monitor whether the crystal head at the local end is in poor contact, which greatly improves the detection efficiency and can also ensure the qualified rate of crimping.

detailed description

Referring to Fig. 1 is the embodiment of a kind of crystal head of the present utility model, a kind of crystal head, comprises shell 1, and the front end of shell 1 is provided with wire groove, is provided with eight secondary grooves 4 in the wire groove, and each secondary wire groove is provided with One electric terminal 2 and eight electric terminals 2 are arranged side by side. Each electric terminal 2 includes two mutually insulated electric sheets 3. There is a space between two electric sheets 3 on the same electric terminal 2. There is a gap or an insulating spacer 5 is provided, and the insulating spacer 5 can be plastic or rubber, which can prevent the contact of the two power strips 3 and can well fix the two power strips 3. The sheets 3 are arranged front and back and are located on the same straight line.

As shown in Figures 2 and 3, a network cable pliers includes a pliers body 6 and a crimping port 7, the crimping port 7 is provided with a bead 8 corresponding to the crystal head electric terminal 2, and each bead 8 includes Two conductive pressing pieces 9, each pressing piece 9 corresponds to a piece of contact piece 3, and the two pressing pieces 9 are insulated from each other, by leaving a gap between the two pressing pieces 9 or setting an insulating spacer 5 To achieve mutual insulation, the pliers body 6 is provided with a power supply 10 and an LED lamp 11, the power supply 10 can be a button battery or a dry battery or a rechargeable battery, the number of the LED lamps 11 is equal to the number of the pressure strips 8, and each LED lamp 11 is connected to the power supply 10 and the corresponding The pressure strips 8 are connected in series to form a series circuit.
