Description

Electrical connector

The present invention relates to an electrical connector having an electrical connector, more specifically, a guide socket and a guide pin, wherein the guide pin is inserted into the guide socket to determine the engagement position of the pair of housings.

Such connectors of the present invention are widely used in copiers, control panels, industrial equipment, electrical applications and power supplies.

Conventional Technology and Challenges

This type of connector is used in the above-mentioned various devices, facilities and apparatuses, and the detachable frequency of the pair of connectors is high, and therefore, the housing of the pair of connectors has guide sockets and guide pins. It is widely used as a lower connector.

However, the guide socket and the guide pin in the conventional connector are merely provided with a function of guiding the engagement positioning of a pair of housings, and there is a lack of consideration of efficiently using the housings. Moreover, according to the conventional connector, two types of housings, a housing having the above guide socket and a housing having the above guide pin, are required, which is uneconomical and disadvantageous in management.

An object of the present invention is to provide a connector that can solve the above problems at one time by relatively simple means.

An electrical connector comprising a housing having a plurality of contact holders on a joining surface of the housing, a guide socket and a guide pin on one bottom, and a plurality of contacts held at the contact holders of the housing, wherein the electrical connectors have the same structure. Designed to mate with a mating connector of the electrical connector such that when the electrical connectors mate, the guide sockets and the guide pins of the two electrical connectors are coupled to each other, wherein the guide socket and the guide pins are collectively adapted to receive respective contacts. In this case, each of the contacts is characterized by coupling with complementary contacts in a mating electrical connector.

The gist of the present invention is provided with a contactor for connecting to the guide socket and the guide pin.

In a preferred embodiment of the present invention, the guide socket and the guide pin are respectively disposed on both sides of the housing; A front end face of the guide pin protrudes in a forward direction than each front end face of the guide socket and the contact holder; Thus, the pair of housings are formed in exactly the same shape, and one side thereof is arranged to be symmetrical with the other side thereof, whereby the coupling is made.

(Example)

An embodiment of the present invention will be described with reference to the drawings.

In Fig. 1, the housing 10 of the connector is made of an electrically insulating material such as plastic. Guide sockets 11a and 11b are provided at both upper ends of the housing 10, and guide pins 12a and 12b are provided at both lower ends thereof, and they extend in the front and rear directions. The guide pins l2a and 12b are formed hollow, and the front half thereof is tapered to gradually increase from the front side to the rear side. The inside of the front half of the guide sockets 11a and 11b is tapered so that the guide pins 12a and 12b are engaged, respectively (see FIGS. 4 and 5). Between the guide socket 11a and the guide pin 12a, and between the guide socket 11b and the guide pin 12b, the coupling groove 13, the contact holder 14, the coupling groove 15, The contact holder 16 is formed sequentially. The guide pins 12a and 12b slightly protrude forward than the guide sockets 11a and 11b and the contact holders 14 and 16 (including the coupling grooves 13 and 15), which are described later in the housing ( 10) facilitates the coupling operation.

In the present invention, two housings 10 having the same configuration as described above are used as a pair of housings, and in use thereof, one of the two housings 10 as shown in FIGS. 2 and 3 is used. It is arranged to be symmetrical with the other side. In such an arrangement, the guide pins 12a and 12b and the guide sockets 11a and 11b on the left side of Figs. 2 and 3 and the guide sockets 11b and 11a and guide pins on the right side ( 12b and 12a are respectively engaged with the contact holder 16, the coupling groove 15 and the contact holder 14 and the coupling groove 13 on the left side, and the coupling groove 13 on the right side. ), The contact retainer 14, the engaging groove 15, and the contact retainer 16 are respectively engaged (see FIGS. 4 to 7).

As shown in FIGS. 4 to 6, the female contact 18 connected to the electric wire 17 is attached to the guide pins 12a and 12b on the left side, and the guide sockets 11a and 11b are provided on the guide sockets 11a and 11b. The male contactors 20 connected to the electric wires 19 are provided respectively. In addition, the male contactor 24 connected to the electric wire 21 is connected to the guide sockets 11b and 11a on the right side, and the female contactor 24 is connected to the electric wire 23 to the guide pins 12b and 12a. Are installed respectively.

As shown in Fig. 7, male and female contacts 27 and 28 connected to electric wires 25 and 26 are connected to the contact holding portions 14 and 16 on the left and right sides, respectively. Since the contacts 27 and 28 are male and female, the contact surface is in the shape of a leaf spring having elasticity, and thus a reliable contact with each other is achieved with a low contact force.

As can be seen from the above, the guide sockets 11a and 11b, guide pins 12a and 12b and the contact holding portions l4 and 16 of the paired housing 10 are arranged to be symmetrical in the same shape. The contacts 22, 20, 18, 24 and the contacts 27, 28 are respectively provided in the pair, thereby forming a pair of connectors. In such a connector, the engagement is started in the state shown in FIG. 3, and thus the engagement is completed in the state shown in FIG. 6 and FIG. Here, it should be noted that the guide pins 12a and 12b and the contact holders 14 and 16, as can be seen from FIG. 2, and also described above, Since the housing 10 of the pair of connectors is engaged, the guide sockets 11b and 11a and the guide pins 12a, which are opposed to each other, protrude slightly forward of the front (including the coupling grooves 13 and 15). 12b) is engaged, and after the coupling has progressed to some extent, the coupling grooves 13 and 15 and the contact holders 16 and 14 facing each other start to engage. This fact shows that this guide socket and the guide pin have a positioning function while guiding the engagement position prior to engagement of the engagement groove and the contact retainer. Therefore, when the pair of housings 10 are engaged, the collision between the contact holders 14 and 16 of one housing and the contact holders 14 and 16 of the other housing caused by misalignment and the one housing contactor are caused. Deformation and damage due to excessive collisional joining of (27, 28) and the contacts (28, 27) of the other housing can be prevented in advance.

1 and 4 to 6, the housing 10 has a bush 30 fitted in a hole 29 formed at both sides. One of the pair of housings 10 is installed by fixing only the bush 30 to a fixing portion of an apparatus or the like (not shown), and the other of the pair of housings 10 is attached to a movable portion (drawer) that slides in the fixing portion. 30) Only fixed installation. By this, there is a slight error, etc. in the installation position of the housings can be absorbed even if the engagement position of the housing is shifted.

In the present invention, it is not particularly limited what kind of contactors are provided in the guide sockets 11a and 11b, the guide pins 12a and 12b, and the contact holding portions 14 and 16. However, it is preferable to use a relatively large current capacitive contactor for the guide socket and the guide pin and a relatively small contact current capacitive for the contact holder.

According to the present invention, in a connector having a guide socket and a guide pin in a housing, a contactor is also provided in the guide socket and the guide pin to be used as an electrical contact portion of the connector. Thus, for example, when using an apparatus such as a copying machine that requires an electrical connection portion having a relatively large current capacity and an electrical connection portion having a relatively small current capacity, a guide socket and a guide pin are used as the connection portion having a relatively large current capacity. Can be used. In addition, the space for occupying the connector can be reduced as compared with the case of using a conventional connector in which a connection portion having a large current capacity and a connection portion having a small current capacity are separate.

In this case, according to the connector of the present invention, since the guide socket and the guide pin are arranged on both sides of the housing, there is a secondary effect that the temperature rise is small even when a strong current is applied to the contacts provided therein.

In addition, since the guide pin protrudes in the forward direction than the guide socket and the contact holder, the pair of connectors can be easily coupled.

In addition, since the pair of housings are formed in the same exact shape, since there is only one type of housing mold, it is very advantageous in terms of economy and management.
